a duster The work can be divided into trial operation and normal operation. The efficiency of the dust collector can be expressed by the gas loss of the dust remover. Cartridge filter The dust collector is composed of filter element or pulse injection. According to the installation methods, the cartridge dust remover can be divided into inclined plug-in type, side mounted type, hoisting type and top mounted type. According to the material of the filter cartridge, the filter cartridge dust remover can be divided into long fiber polyester filter cartridge dust collector, composite fiber cartridge dust collector, anti-static cartridge dust collector, flame retardant cartridge dust collector, membrane filter cartridge dust collector, nano cartridge dust collector, etc. First of all, it is necessary to check the single component of the system, and then carry out adaptive work and functional test of the components. The dust collector is composed of filter element or pulse jet. According to the installation methods, the cartridge dust remover can be divided into inclined plug-in type, side mounted type, hoisting type and top mounted type. According to the material of the filter cartridge, the filter cartridge dust remover can be divided into long fiber polyester filter cartridge dust collector, composite fiber cartridge dust collector, anti-static cartridge dust collector, flame retardant cartridge dust collector, membrane filter cartridge dust collector, nano cartridge dust collector, etc. In normal operation, necessary inspection should be carried out, especially the function of filter cartridge dust collector, and the influence of load change of main equipment on the function of dust collector should be paid attention to. After starting the machine, pay close attention to the working condition of bag filter. You should pay attention to the test of the filter cartridge dust removal device

As shown in Figure 1, the direction of fan rotation, rotation speed, vibration and bearing temperature.

2. Whether the air volume of the treatment system and the pressure and temperature changes of each test point are consistent with the design requirements.

3. Adjust the cleaning cycle and cleaning period.

4. What's the situation of the filter mouth, the use of the filter bag, and whether it's a loose bag,

5. Pay attention to the non-existent dewing in bag room and unsmooth ash removal system.

You should pay attention to your work

1. Work related records, the development of each ventilation and dust removal technology system must be equipped with necessary test appearance, whether it is necessary to analyze and measure the timing information in normal operation, and accurately record it.

Figure 2. Air flow resistance. The u-meter can be used to determine the operating conditions: if the pressure difference increases, it means that the filter bag is blocked, water vapor condenses on the filter bag, the ash cleaning mechanism fails, the ash content in the ash hopper is too much, which causes the filter bag to be blocked, and the gas flow rate increases.

3. It should be safe. Special attention should be paid to the use of bag filter to prevent combustion, explosion and fire.
