Manufacturers of dust removal equipment introduce dust collectors . A. Air volume: Air volume refers to the amount of gas that can be purified per unit of time. Units are cubic meters per hour (m3 / h (ibid.) Or standard cubic meters per hour (nm3 / h). It is one of the important contents of the design of the bag filter. When designing or selecting a bag filter based on the air volume, it is usually impossible for the filter to exceed the specified air volume. Otherwise, the filter bag will be randomly blocked and used. The life will be shortened, the pressure loss will be greatly increased, and the dust removal efficiency will be reduced. But the air volume cannot be selected too much, otherwise it will increase the equipment investment and air volume. The reasonable selection and treatment of air volume is often determined according to process conditions and experience.
Manufacturer of dust removal equipment introduces dust collector, b. Working temperature: For bag dust collector, its working temperature depends on two factors, one is the high bearing temperature of the filter material, and the other is the temperature of the gas must be higher than the dew point temperature. Currently, Due to the selection of a large number of glass fiber filter materials, the operating temperature can reach 280 ° C. Gases higher than this temperature must be cooled, and gases lower than the dew point temperature must be heated. PPS filter materials are usually used more. The temperature is 170 degrees. For bag filters, the relationship between temperature and dust removal efficiency is not obvious, unlike electric dust collectors. For electric dust collectors, temperature changes will affect the specific resistance of dust Factors affecting dust removal efficiency.

Pressure loss: The pressure loss of bag dust collector refers to the pressure drop or resistance of gas from the inlet to the outlet of the dust collector. The pressure loss of bag dust removal mainly depends on the following three factors:
1. Pressure loss of equipment structure.
2. Filter material pressure loss. It is related to the properties of the filter material (such as porosity, etc.).
3. Pressure loss of ash layer on filter material.
Dust removal equipment manufacturer introduces dust collector d. Dust concentration at the outlet: Dust concentration at the outlet refers to the emission concentration of the dust collector, which is the same as the inlet. The dust concentration at the outlet should be determined according to local environmental protection requirements or user requirements. Up to 50g / nm3.
和处理风量选择自己的型号或并联组合，并可根据需要提供碳钢或不锈钢制的除尘器. The manufacturer of Yuchen dust removal equipment has a simple and reasonable structure, with a small air volume, and can be installed indoors or outdoors. Users can choose their own model or parallel combination according to their own needs and air volume, and can provide carbon steel or stainless steel dust collectors as required. .
Working principle: Dust-containing gas enters the bag filter from the air inlet, stops filtering through the surface of the filter bag, and the purified gas flows from the inside of the filter bag to the cavity, and is discharged from the air outlet through the venturi tube. When adsorbed in the filter bag When the dust on the surface reaches a certain value, the program will stop the pulse spraying at regular intervals, that is, while the purified gas is blown back into the filter bag, high pressure air is sprayed into the venturi tube to form a large pressure difference, which will dust Clean it down to achieve the purpose of dust removal. The resistance of the entire equipment and system remains stable. The blown back dust falls to the bottom of the lower box and is discharged by the screw conveyor for recycling.
