[0002] In recent years, with the popularization of environmental protection concepts and the development of technology, the application of filter cartridge dust collectors has become more and more extensive. Market demand continues to grow, and the future development prospects are broad. With the development of science and technology, the technology of filter cartridge dust collectors is also constantly innovating to improve its performance and efficiency and meet more stringent environmental protection standards. At present, most of the filter cartridge dust collectors are horizontally mounted / obliquely mounted filter cartridge structures. Affected by gravity, the dust on the upper surface of the filter cartridge will be adsorbed on the surface of the filter element for the second time during backblowing, resulting in incomplete backblowing and cleaning of the filter element.

[0029] An air outlet component is arranged on the top of the fan chamber 1, and the air outlet component is an air outlet or an air outlet duct, and can be arranged according to specific working conditions.

[0030] The fan chamber 1 comprises a fan chamber housing, and a fan 10 is arranged inside the fan chamber housing. The fan 10 is arranged on a fan mounting plate, and the fan mounting plate is fixed on the fan chamber housing.

[0031] The back-blowing chamber 2 comprises a back-blowing chamber shell, in which a back-blowing assembly 7 is arranged, and a blowing port of the back-blowing assembly 7 is arranged toward the top of the filter cartridge.

[0032] The back-blowing assembly 7 includes an air bag, which is connected to a compressed air pipeline. A plurality of compressed air branch pipelines are arranged above and below the air bag. A blowing port is arranged at the end of the compressed air branch pipeline, and the blowing port is arranged directly opposite the top of the filter cartridge. The number of the blowing ports is the same as that of the filter cartridge, and a solenoid valve is arranged on each compressed air branch pipeline, and a pressure reducing valve is arranged at the outlet of the air bag.

[0033] Pressure tapping ports are arranged at the upper and lower end surfaces of the filter chamber, and the pressure tapping ports are connected to the pressure sensor through pipelines.

[0034] The back-blowing chamber 2 is also provided with an electric control box, which includes a PLC control system, and the solenoid valve, the pressure reducing valve, the fan 10, and the pressure sensor are respectively connected to the PLC control system. The specific model is not limited, as long as the working components and parts function are realized.

[0035] The air bag is connected and fixed to the wall plate of the back-blowing chamber shell by bolts.

[0036] The filter chamber 3 comprises a filter chamber shell, and a plurality of filter cartridges are vertically arranged inside the filter chamber shell. The top of the filter cartridge is fixed on the top wall plate of the filter chamber shell, and the number of the filter cartridges can be set according to the working condition requirements.

[0037] A through hole is arranged on one side of the filter chamber housing adjacent to the back-blowing chamber 2, and the through hole is arranged corresponding to the top size of the filter cartridge. The number of the through holes is the same as the number of the filter cartridges, and the back-blowing assembly 7 can blow toward the filter cartridge.

[0038] The filter cartridge is a filter element, and the filter element is preferably a filter element of F9 or above.

[0039] The ash cleaning chamber 4 includes an ash cleaning chamber shell, which is connected to the bottom surface of the filter chamber shell. An ash hopper is arranged on the ash cleaning chamber shell, and an ash car 9 is arranged below the ash hopper. The ash hopper is welded to the ash cleaning chamber shell.
