With the continuous development of science and technology, the continuous improvement of people's living standards, environmental awareness is more and more popular, whether in urban or rural areas, people's environmental awareness is constantly enhanced, so what is the development prospect of stand-alone pulse precipitator manufacturers? The quality of our living environment affects our health, and environmental protection issues also have corresponding influence on the development of enterprises. In this case, the single pulse bag dust collector has gradually become widely used, and its excellent performance has won the attention of the majority of users and enterprises.
The intake manifold specification of the air bag of the dust removal equipment should be selected as large as possible to consider the rate of replenishment of qi and blood. For large space air bag, several air bags can be connected into a gas storage control loop with 3 inch pipe. The gate valve is installed on the upper end or side of the air bag of the dust removal equipment to prevent the oil and water in the air bag from blowing into the filter bag through the pulse solenoid valve gas generator, which harms the actual effect of dust removal and the dust removal rate of the cloth bag type dust collector. The bottom of each air bag needs to contain automatic or manual water and oil filter valves, which are conducive to periodically discharging the residue inside the vessel. If the air bag of the dust removal equipment is designed according to the standard of the pressure vessel, and has sufficient large capacity, it means a reduced gas pressure stabilizer tank itself, without another installation. When there is another pressure regulating tank in front of the air bag, it is necessary to install the pressure regulating tank as close as possible to the air bag, so as to avoid reducing the working pressure of the gas through the long and thin pipeline in the whole process of transportation. It is important to note that the air bag of the dust removal equipment is completed after the production, processing and manufacturing. It is necessary to apply compressed air to clean the internal welding of the gas producer first, and then install the gate valve.

high vacuum fume extractor supplier should prevent the gas from cooling below the dew point in the bag room, especially the use of pulse dust collector equipment under negative pressure. Because the shell often has air leakage, so that the gas temperature in the bag room is lower than the dew point, the filter bag will be damp, resulting in dust is not loose, but sticky attached to the filter bag, the fabric hole is blocked, resulting in dust removal failure, so that the dust collector pressure drop is too large, can not continue to run, some paste bag can not dust.
high vacuum fume extractor supplier close a chamber lifting valve, cut off the filter air flow, and then open the electromagnetic pulse valve, compressed air in a short time to expand in the upper box, into the filter bag, so that the bag expansion deformation vibration, and under the effect of reverse airflow scour, Dust attached to the outer surface of the filter bag is stripped and dropped into the ash hopper. After the cleaning is completed, the electromagnetic pulse valve is closed, the lifting valve is opened, and the chamber is restored to the filtering state. Cleaning each room in turn, from the beginning of room cleaning to the next cleaning for a cleaning cycle. After filtration and dust removal work is intercepted into the ash hopper, and then by the ash hopper mouth of the ash discharge device.

The important role of the manufacturer of welding and cutting dust products in cooling: Because the temperature of the flue gas is as high as 550° at some times, the manufacturer of welding and cutting dust products can not be used to this environment, so we should choose three cooling methods for the dust collector. Set a gas cooler in the manufacturer of welding and cutting dust products, it can assist in lowering the temperature of the air, air and water, some cool wind and water cooling occur. These cool breezes and cold water are able to assist in cooling the smoke and then decrease the warmth of the bag dust collector. Cloth bag dust collector is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. manufacturer of welding and cutting dust products at high temperature, you can install a cool air valve, the cool air valve is mainly to avoid some high temperature flue gas into the dust collector, it is to play the function of conditioning, its one end is connected with high temperature pipe, And the other end is connected to the atmosphere. Therefore, before using the manufacturer of welding and cutting dust products, it is better to install these devices. In this way, the function of the dust collector can be carried forward, and the dust collector will not be damaged due to unacceptable high temperature. Some low-temperature flue gas can be properly mixed. If the temperature of the gas in the dust collector is not the same, the best way is to mix a part of the low-temperature gas into the high-temperature flue gas first, so that the gas can be mixed and the temperature in the dust collector is not so high.
There are many kinds of manufacturer of welding and cutting dust products, so its selection accounting is very important. Improper selection, such as equipment is too large, will not form the flow cost; Equipment selection will affect production, difficult to satisfy the environmental requirements. The manufacturer of welding and cutting dust products resistance value is a problem that can not be ignored, it is directly related to the type selection and numerical determination of dust precipitator. The resistance of the manufacturer of welding and cutting dust products consists of the following 3 parts:
First, the resistance of the dust removal equipment body structure refers to the resistance of gas from the dust collector to the dust collector inlet;
Two, the resistance of the dust bag, refers to the resistance of the filter material to filter dust, about 50~150Pa;
Three, the resistance of the dust layer on the surface of the dust bag, the resistance of the dust layer is about 1~10 times that of the clean press cloth.
manufacturer of welding and cutting dust products off-line pulse cleaning. It is a kind of unit combination dust collector with large air volume, good dust removal effect, good dust removal rate, convenient operation, maintenance and small footprint. The body of pulse dust collector adopts special treatment and has good service life. Foundry is more suitable for the use of bag dust collector, bag dust collector body structure is mainly through the upper part of the box into the middle box through the air inlet pipe, later by the lower box (ash bucket), dust cleaning system and exhaust mechanism and other parts. Pulse dust collector dust removal rate is good, can capture particle size of more than 0.3 micron fine dust, dust removal rate is good, and the structure is relatively simple, stable operation, less initial investment, convenient maintenance. In addition to the correct selection of bag material, the dust cleaning system plays a decisive role in the performance of bag dust collector. Therefore, the cleaning method is one of the characteristics to distinguish the bag dust collector, but also an important link in the operation of the bag dust collector.
manufacturer of welding and cutting dust products Dust properties include specific resistance, particle size, true density, bailing property, hydrophobicity and hydrohardness, flammability, explosion, etc. Dust with too large or too small specific resistance is not suitable for electrostatic precipitator, bag type dust collector is not affected by the specific resistance of dust; The concentration and particle size of dust have a significant effect on the rate of electrostatic precipitator, but not on the bag precipitator. When the dust concentration of the gas is good, the pre-dust removal device should be set up before the electrostatic precipitator. The type of bag dust collector, the way of cleaning dust and the filtering wind speed depend on the nature of dust (particle size, scoop); Wet dust collector is not suitable for purifying hydrophobic and hydraulic dust: the true density of dust has significant influence on gravity dust collector, inertia dust collector and cyclone dust collector. For the new adhesion of large dust, easy to lead to dust collector working face cat knot or blockage, therefore, it is not suitable to use dry dust removal; When the dust can produce combustible or explosive dangerous mixture after water purification, wet dust collector can not be used.

With the accumulation of dust on the surface of the filter material, the rate and resistance of the function of cyclone separator are increased accordingly. When the pressure difference on both sides of the filter material is very large, some of the fine dust particles have been attached to the filter material will be squeezed in the past. The rate of function of cyclone separator decreases. In addition, the function of cyclone separator resistance is too high will make the air volume of the dust removal system decreased significantly. Therefore, after the resistance of the function of cyclone separator reaches the value, the ash should be cleaned in time. Do not destroy the initial layer when cleaning, so as not to decrease the rate. General new filter material dust removal rate is not high enough. Filter material used for a period of time, due to screening, collision, retention, diffusion, electrostatic and other effects, the surface of the bag accumulated a layer of dust, this layer of dust is called the first layer, in the process of movement after this, the first layer became the main filter layer of the filter material, relying on the role of the first layer, large mesh filter material can also obtain a better filtration rate.
function of cyclone separator is a dry dust removal device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and the dust containing gas is filtered by the filtration effect of fiber fabric. When the dust containing gas enters the function of cyclone separator, the dust with large particles and heavy ratio will settle down due to the action of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified. function of cyclone separator The working mechanism of cyclone separator is that the dust particles are filtered down by the dust-containing gas through the filter material. The coarse dust is mainly captured by the filter material by inertial collision, and the fine dust is mainly captured by diffusion and screening. The dust layer of filter material also has filtering effect.
Features of function of cyclone separator:
1, fine dust, generally up to more than, can be used in the purification requirements of the occasion.
2, strong adaptability, can capture all kinds of nature of dust, and does not affect the dust removal rate due to the specific resistance properties of dust, adapt to a wide range of dust concentration, and when the inlet concentration or smoke volume changes, will not affect the purification rate and operation resistance.
3, easy to recycle materials, no pollution, waste water and other secondary pollution.
4. Various specifications and flexible use. The treated air volume can range from several hundred to several million cubic meters per hour.
5, by the filter media is not afraid of temperature, such as performance restrictions, the use of temperature can not be too high, some corrosive gases can not be selected.
6. When collecting dust with strong viscosity and hygroscopic property or dealing with flue gas with high dew point, it is easy to block the filter bag and affect the normal work.
7. function of cyclone separator has the problems of large area, easy damage of filter bag and high maintenance cost.

fume extractor carbon filter elements form electric currents due to the movement of ions. To begin with, there are fewer free ions in the air and less current. When the voltage rises to the corresponding value. After the power is switched on, the ions near the discharge get a good energy and speed. When they hit the neutral atoms in the air, the neutral atoms will break down into positive and negative ions. This phenomenon is called air ionization. Basically, it is widely used in cement or non-ferrous metals and garbage incineration, as well as in various industries such as mechanical and chemical engineering. Moreover, it can also see dust removal equipment in some serious places. Most of the dust is deposited on the corona and accumulates for a long time to reach the corresponding weight. Due to the gravity, the dust falls into the collection tank to complete the dust removal function.
fume extractor carbon filter element gas bag after processing and production what are the problems?
1. If the dust collector air bag is designed according to the pressure window standard and has a large enough cellar, the basic body is a compressed gas stabilized gas tank. When there is a stabilizing tank in front of the dust collector's air bag, it is necessary to install the stabilizing tank near the dust collector's air bag in the day to prevent the compressed gas from losing pressure through the slender pipe in the conveying process.
Second, fume extractor carbon filter element gas bag after processing and production, continuous injection with compressed gas to clean the internal welding slag, and then install the valve. When testing the pulse valve in the workshop, especially the 76mm diameter submerged valve, determine the pressure of the dust collector's bag compressed gas and the replenisher gas flow, otherwise the pulse valve will not be able to open or leak.
Three, if after installation on site, it is found that the upper air outlet of the valve leaks. That is because the dust collector air bag contains impurities, resulting in the accumulation of rust on the small diaphragm can not close the valve, the need to remove the small diaphragm cleaning.
Four, dust collector air bag is a pressure vessel, after manufacturing should be done not afraid of pressure test, test pressure is 1.5 times of the working pressure is appropriate. Consider and quality requirements when designing air bag of circular or square cross-sectional dust collector.
5. The bottom of each dust collector's air bag is equipped with automatic (i.e., two-position two-way solenoid valve) or manual oil-water blowdown valve, periodically discharging the impurities in the container.
fume extractor carbon filter element can cause dripping in the pipe during processing, making the lower part of the tank also collect water, this problem can cause moist compressed air blown in into the bag filter, bags will increase. In severe cases, corrosion of the cage can cause damage to the filter bag, which will affect the normal use of fume extractor carbon filter element.
The impurities in the compressed air should be filtered at first, and then the pressure difference should be adjusted to clean the fume extractor carbon filter element without affecting the normal use of the fume extractor carbon filter element. It is reported that fume extractor carbon filter element's resistance will increase after being used for a long time. I don't know why. In practice, this problem can occur due to long intervals between blowing periods. As the fume extractor carbon filter element types used by different industrial enterprises are different, the parameter Settings are not different. fume extractor carbon filter element has a long blowing interval, which on the one hand can extend the service life of the filter bag, but on the other hand, it will increase resistance. The setting of blower parameters should be based on the actual application.

What are the precautions for the environmental conditions when using purchase welding fume collector.
1. Pay attention to the ambient temperature in order to correctly determine the material of construction. Acidic or alkaline gas requires anti-corrosion treatment on the purchase welding fume collector air duct. In humid air environment, the purchase welding fume collector needs to be strengthened with anti-rust treatment or made of anti-rust materials. If there are high-temperature particles in the dust-laden air, add a fire-proof pre-filtering device before the purchase welding fume collector, such as a fire-proof filter box, a water spray cooling system, or a metal blocking filter.
2. For the purchase welding fume collector installed outdoors, the influence of climate and wind direction on it should be considered. It is better to install a canopy above the purchase welding fume collector; the air outlet should avoid facing the residential area, office area or human and animal activity area. If the outlet air needs to be discharged at a high altitude, a chimney should be installed.
3. For the purchase welding fume collector installed indoors, its weight, size and support should be considered. Where there is a potential for explosion, consider installing sprinklers. It is also necessary to consider the noise of the fan during operation, which should generally be lower than 75dB. If it is higher than this data, a muffler should be installed to reduce noise.
