Among all kinds of dust removal devices, the bag dust collector in the chemical factory has excellent dust removal performance, and the air volume is handled from hundreds of cubic meters to millions of cubic meters per hour. Moreover, maintenance and management are relatively simple and easy, so all kinds of bag dust collectors in chemical plants are widely used. However, whether it is the design or operation of bag dust collectors, there is a big gap between practical experience and theoretical experience.

Dust removal equipment evaluation index Dust removal equipment evaluation mainly includes the following contents.
(1) The main technical performance of the dust collector meets the design index. Including treatment air volume, air leakage rate, dust removal efficiency, emission concentration and special technical indicators.
(2) The dust collector achieves stable performance and long-term reliable continuous operation. The dust removal rate meets the design requirements, and the equipment is intact and synchronous operation rate are relatively high.
(3) The operating cost indicators of various dust removal equipment are clear, and the operating cost indicators are included in the production cost management.
(4) Establish a regular dust removal equipment operation and management system. When there are problems with the operation of the dust collector, necessary improvement measures are easily taken.
After construction and adjustment, when the bag dust collector is operated normally, in addition to setting up a dedicated person to manage and maintain, employees need to be mobilized to carry out management and maintenance, and a combination of dedicated person management and employee maintenance is implemented. Strictly implement the operation management system and give full play to the effectiveness of the dust collector. Practice has proved that if the dust collector is not managed properly, even a good dust collector will not achieve the expected results. As for bag dust collectors, if the management is not good, the dust removal efficiency cannot be guaranteed during operation, and the bag dust removal efficiency will be greatly reduced, resulting in the bag dust collector failing. Therefore, when the bag dust collector is put into production, it is necessary to explain to the operator the importance of the maintenance and management of the dust collector. Only by mobilizing employees to do a good job in maintaining and managing the dust collectors and give full play to the effectiveness of the equipment. If you choose a suitable dust collector, if you do not carry out scientific maintenance and management, it will not be possible for the dust collector to operate normally for a long time. Only by carefully maintaining and managing the dust collector can the dust collector be in good operation and extend its service life.

The main performance indicator of the dust collector, the pulse air flow is directly sprayed into the filter cartridge without passing through Venturi. This will cause one end (upper part) of the filter cartridge to bear negative pressure near one end (upper part) of the pulse valve, and the other end (lower part) of the filter cartridge to bear pressure. This will cause different cleaning of the upper and lower parts of the filter cartridge, which may shorten the service life and prevent the equipment from achieving effective cleaning.
For this purpose, a venturi nozzle for filter cartridges can be installed at the pulse valve outlet or pulse blowing pipe. The distribution of the blowing pressure is improved to a relatively uniform full-filter cartridge height positive pressure spray.
Dust accumulation in the folding joints of the filter cartridge will make cleaning difficult. Therefore, filter cartridges with large folding area (the filter area of ​​each filter cartridge reaches 20~22m2) are generally only suitable for use in situations with lower inlet concentrations.
The air distribution box of the pulse injection device of the filter cartridge dust collector shall comply with the provisions of JB/T 10191-2000. The clean air flow should be water-free, oil-free, and dust-free. Under the specified conditions, the injection valve and interface should have no air leakage, and can be opened and closed normally, and work reliably.
The pulse controller should work accurately and reliably, and its spraying time and interval can be adjusted within a certain range. When the induction blowing device is installed in conjunction with the blowing pipe. The nozzle of the inducing blowing device should be coaxial with the nozzle hole on the blowing tube and maintain a perpendicularity consistent with the nozzle, with a deviation of less than 2mm.
