Filter cartridge a duster Not only as a kind of high-efficiency dust removal system equipment, but also we have a kind of development of energy-saving and environmental protection equipment Cartridge filter To carry out a comprehensive maintenance and management, it is necessary to analyze and check the internal control of the dust remover, and check whether the reducer is flexible and lubricated. 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. It can be divided into fiber filter, filter cartridge, filter cartridge, etc. A device that separates dust from flue gas. The performance of the dust remover is expressed by the amount of gas that can be treated, the resistance loss of gas passing through the dust collector and the dust removal efficiency. The dust removal company introduces the maintenance steps before the operation of the dust remover

As shown in Fig. 1, check that the ash discharge device and the dust device of the drum type dust collector are in normal operation as required;

2. The work management personnel must carry out a comprehensive inspection on the internal control of the filter cartridge dust collector, whether the reducer can rotate flexibly and lubricate, and check the operation of the ash hopper unloading equipment. These enterprise accessories must be in normal operation;

3. The installation of industrial filter cartridge dust remover, the site is clean, the road is smooth, the operation inspection platform, aisle handrails are complete, the lighting is sufficient, there are shields or baffles outside the rotating mechanism, the control room should have effective cooling, dust and fire prevention measures; (consult the dust collector hotline: 400-636859)

4. After checking the dust remover body, close and lock the manhole door of all work; (how to choose as a good technical equipment of mine dust collector? In the new year, we can consult the limited company and help you design the dust control scheme for free.)

As shown in Fig. 5, the dust collector is installed, and in response to the storage bag, bag and partition, check that there is no contact between the bottom of the bag;

6. The compressed air system management staff must pass normally, the switch positions of ash cleaning system are correct, and the pressure gauge and differential pressure gauge display normally;

As shown in Figure 7, in the first 4 hours, the system is started or in the furnace, heat is input into the hopper and hopper to prevent moisture condensation caused by bypass or gray or ash blockage;

8. Check the tightness of the air path of the ash cleaning control system, and ensure that there is no leakage. The development of the electromagnetic pulse valve must be uniform and flexible;

Before the new bag is put into operation for the first time, or before the boiler is cooled, the cloth bag must be pre coated for protection. A device that separates dust from flue gas. The performance of the dust remover is expressed by the amount of gas that can be treated, the resistance loss of gas passing through the dust collector and the dust removal efficiency. The coating method and parameters are detailed in the technical requirements. The precoating must be completed on the day when the main engine ignites the furnace. When the main engine can't catch fire again after the bag is pre dusted, the ash cleaning system should be opened to clean the bag ash layer, and pre ash should be carried out before the next host machine, so as to prevent the ash layer on the surface of the bag from being damped and pasted;

Figure 10. For circulating fluidized bed boiler, due to the long combustion time of fuel oil, in order to prevent the influence of oil fume on cloth bag, it is necessary to prepare ash tank and other equipment which eject dust during the combustion process;

11. Diesel fuel, not heavy;

12. Pre coating operation method
