The working mechanism of dust collector precautions for use is that the dust particles are filtered down by the dust collector precautions for use. The coarse dust is captured by the filter materials mainly by inertial collision, and the fine dust is captured by diffusion and screening. The dust layer of the filter material also has a filtering effect. Air leakage rate is required to be less than 3%. If the dust collector precautions for use are air leakage, the dust removal rate will be affected, and the service life of the equipment will be affected to a corresponding extent. Generally, dust collector precautions are in negative pressure operation. If the equipment is not tightly sealed or there are other air leakage conditions, a small loop will be formed inside the equipment, and it may also reduce the system temperature, which is easy to cause the paste bag situation, affecting the dust collection effect. Heat preservation is to determine the temperature of the filter gas to avoid damage to the filter material caused by high temperature, or too low temperature, so that the humidity increases resulting in the occurrence of filter bag paste bag.
dust collector precautions for use in the filter bag storage and installation requirements are as follows:
First, the installation of filter bag requirements: it is recommended to be installed by two people, one person will fold the cloth bag lengthwise into the flower plate hole, and the other person will grasp and open the filter bag into a roll. The cage frame should be aligned with the center, placed gently, and installed vertically.
Second, the installation personnel should be dressed in concise, clean pockets, can not carry cigarettes, matches, lighters, keys, knives and other objects, so as not to fall into the filter bag. (If the filter bag falls into the debris need to remove). Do not wear shoes with nails or hard soles for installation.
Third, the flower plate after the installation should be gradually covered with canvas to avoid debris falling into the filter bag. When installing the spray pipe, cover the flower plate with canvas to prevent damage to the filter bag mouth.
Fourth, installation environment requirements: the installation site lighting is sufficient, the site is not allowed to store unrelated to the installation of equipment, debris, etc.
Fifth, filter bag installation inspection: after installing a filter bag, check whether the joint joint is sealed and whether the sealing position is correct. Check whether it is vertical from the ash hopper. If it is found that the bottom of the filter bag meets or is incorrect, it is necessary to make a record and adjust it in time under the guidance of a special person.
6, the filter bag installation process, no smoking, any form, any part of the welding and cutting work, power is strictly prohibited with lighters, matches and other lighting, every day after the installation of the work to check the installation tools, so as not to miss into the filter bag damage filter bag.
7. When storing filter bags, attention should be paid to keeping them away from fire, avoiding direct sunlight and other strong light, and preventing heavy objects from being squeezed. Each filter bag should be inspected before installation to prevent mechanical damage.

The operating mechanism of a dust extraction arm supplier is that dust particles are filtered after the dust-containing gas is filtered through the filtering data. The coarse dust collected by the filtering data mainly depends on the effect of inertia bumping, while the fine dust collected mainly depends on the effect of dispersion and screening. The dust layer of filter material also has filtering effect. With the accumulation of dust on the surface of the filter material, the power and resistance of the dust extraction arm supplier will increase accordingly. When the pressure difference between the two sides of the filter material is very large, some fine dust particles attached to the filter material will be kneaded to reduce the power of the dust extraction arm supplier.
How does a dust extraction arm supplier deal with hot and humid gases? Below, give you a detailed introduction:
1. The dust removal function of the dust collector producing paste bag fails, the resistance is too large, and the operation condition is good. To prevent the dust extraction arm supplier from forming dew paste bags, it is necessary to keep the body temperature 25~35℃ above its dew point.
2. When the dust collector is used to deal with high temperature and high humidity gas, a temperature detection and alarm device shall be installed at the entrance for monitoring, and rock wool and other insulation materials shall be installed outside the shell for insulation.
3. The dust collector should be strictly sealed and the air leakage rate should be less than 3%. Welding quality is important during equipment installation. All welding shall be carried out in accordance with the corresponding codes and standards. After welding, kerosene and phosphor shall be used for leakage inspection, and the air leakage shall be re-welded.
4. When a dust extraction arm supplier deals with high temperature and humidity gas, if the gas temperature is lower than the dew point during operation, the water vapor will condense and make the filter bag damp. A large amount of dust will adhere to the surface of the filter bag and block the pores of the filter bag.
V. The dust extraction arm supplier usually works under negative pressure. If the equipment leaks, it will inhale a large amount of external air and rain, which will cause the filter bag to be damp and harden and increase the operation resistance.
Six, before the dust removal system stops running, it is necessary to discharge all the wet gas in the dust collector and replace it with dry air to prevent condensation. That is to say, after the production equipment stops running, the dust removal fan should be extended for a period of time before stopping.
The dust extraction arm supplier's compressed air device includes gas tank, air compressor station, pneumatic triplet of pipeline, etc. For the dust extraction arm supplier, there is also air separator, spray pipe, etc. The dust extraction arm supplier's dust removal power source comes from compressed air. The compressed air equipment usually uses oil-free compressors or ordinary compressors for refueling and dehydrating. However, in order to determine the quality of the compressed air, the design of the compressed air station should be as close to the dust collector as possible to avoid condensation in the pipeline. In addition, compressed air station is used as far as possible to determine the stability of compressed air pressure for large pulse precipitator.
If it is not possible to design the air compressor station or the air compressor station is not near the dust collector, the compressed air tank should be set near the dust collector equipment, so that the pressure of the compressed air source can be stable. On the other hand, the condensed water generated on the compressed air pipeline can also be discharged regularly through the valve at the bottom of the compressed air tank, so as to determine the quality of the ash source of the pulse dust collector.
dust extraction arm supplier is suitable for all kinds of vertical dust generation points, flexible and convenient, local dust collection, local treatment, can achieve air cleanliness. The basic structure is composed of dust removal box, centrifugal fan, filter bag (filter cylinder), dust collector and microcomputer controller, etc. The dust is sucked into the dust collector box by the negative pressure of the fan through the suction pipe, and the coarse dust is initially filtered by the filter and directly drops to the dust collector by gravity. The fine dust is captured by the filter on the outer surface. The clean gas flows into the clean room after filtration, decomposition and purification through the filter element, and is discharged from the outlet by the fan.
