Abstract: An air filter device and an operating method thereof. The air filter device comprises an air filter system and a powder distribution system. The air filter system comprises an air filter chamber (1), a clean air chamber (2), and a high-pressure jet pulse powder cleaning device (3). An entrance of the air filter chamber (1) is in communication with an air inlet pipe (4); an exit of the clean air chamber (2) is in communication with an air outlet pipe (6), and the air outlet pipe (6) is in communication with an exhaust fan (9). A plurality of bag filters or filter cartridges (10) are disposed in the air filter chamber (1). An opening end of each of the bag filters or filter cartridges (10) is in communication with the clean air chamber (2), and high-pressure jet pulse powder cleaning devices (3) are disposed above the opening end of the corresponding bag filters or filter cartridges (10).

Abstract: The present invention belongs to the field of environmentally dust removing equipment apparatus, and specifically relates to a dust remover with a thickness-controllable, sorted and continuous accumulation shelf layer, and an operation method thereof. The dust remover comprises a gas purification chamber, a dust filtration chamber, an ash bucket and a high-pressure gas pulse-jet deashing device. A valve is provided on the exhaust gas inlet pipe and/or the purified gas outlet pipe. The distance L from the inlet pipe valve to the exhaust gas inlet of the filtration chamber is 0-1.0 m or 1.0-10 m. Two or more dust removers are communicated with the dust source separately or in parallel, so as to form a group of dust removers. When the dust remover performs off-line deashing, the valve on the exhaust gas inlet pipe and/or the purified gas outlet pipe is closed, and the pulse-jet deashing device is started up to perform jet deashing.
