Abstract

The invention relates to a high temperature resistant dust collector, which comprises a heat insulation shell, a dust hopper, a pulse blowing device, a metal filter cartridge, a filter chamber, a purified gas outlet, a dust containing gas inlet and a dust conveying device. The dust hopper is connected to the bottom of a tank body of the filter chamber; one side of the dust hopper is provided with the dust containing gas inlet which is communicated with the filter chamber; one side of the top of the heat insulation shell is provided with the purified gas outlet which is communicated with a clean chamber; the metal filter cartridge is arranged in the filter chamber, and is made of a high temperature resistant metal material; a nozzle of a blowing pipe in the pulse blowing device aligns to the metal filter cartridge; and the dust conveying device is connected to the lower part of the dust hopper. The filter material of the high temperature resistant dust collector is special metal fiber, and can be applied to a flue-gas at 300 to 1,000 DEG C to replace multiple cooling devices such as a water-cooling flue, an air cooler and the like in a dust removing system; and the high temperature resistant dust collector has high collection efficiency, low energy consumption, and safe and stable operation of the system, and realizes the dust removing of high temperature flue gas of equipment such as electric stoves, oxygen argon decarbonization converters and the like.

Description

technical field [0001] The invention relates to metallurgical dedusting equipment, in particular to a high-temperature resistant deduster applicable to flue gas temperatures ranging from 300°C to 1000°C. Background technique [0002] At present, in the field of high-temperature flue gas dust removal in China, there is no high-temperature-resistant dust collector that operates continuously at 300°C to 1000°C. Therefore, the range of design and equipment selection for high-temperature flue gas dust removal is limited, and for this reason, multiple cooling devices are used to cool the dust removal system or a large amount of cold air is mixed in, which wastes energy and increases the investment and maintenance of cooling equipment. Work. [0003] Chinese Patent Literature Announcement No.: CN201041360 discloses a boiler flue gas dust collector, which includes a pool and a housing mounted on it, the housing is provided with a smoke inlet and a smoke outlet, and the housing is p...
