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.
