A bag type dust collector for industrial environmental protection dust removal

Abstract

The invention discloses a bag-type dust collector for industrial environment-friendly dust removal. Its structure includes an air suction port, an upper cover, a filter cylinder, and a dust collector. The filter cartridge is docked with the dust collector, and the two are connected internally. The bundle sleeve is threaded and locked with the dust bag through the ring top plate, and is stretched under the action of the expansion part to elastically lock the dust bag. It can prevent the dust bag from stretching and shaking due to the impact force of the dust when the exhaust gas that impacts downward is ejected from the support and guide device to the expansion part. The structure of the dust collection bucket is The upper and lower conical shapes are convenient for ash discharge, and through the cooperation of the dispersion structure and the dispersion pipe, the wind direction is more dispersed, and the exhaust gas and dust in the dust collection bucket are more evenly distributed, and the dispersion structure can play a certain buffer function, so that the impact on itself will be reduced.

Description

technical field [0001] The invention relates to the field of industrial environmental protection, in particular to a bag-type dust collector for industrial environmental protection dust removal. Background technique [0002] The existing bag-type dust collector bag cage is usually made of rigid material, including vertical ribs and ring ribs. The vertical ribs and ring ribs form a cylindrical keel, and the dust bag is fixed on the keel by fixing means. [0003] After using for a period of time, a large amount of dust will be stained on the mouth of the dust bag. Since the bag cage is made of rigid material, high-pressure air is generally used to blow the dust into the dust bag at high speed in a short period of time to remove dust, resulting in dust bag The fiber gap of the bag mouth is frequently stressed, which increases the damage and replacement rate of the filter bag, and if the temperature drops to condensation, a large amount of acid, alkali and hygroscopic dust will...

Problems solved by technology

[0003] After using for a period of time, the bag opening of the dust bag will be stained with a lot of dust. Since the bag cage is made of rigid material, high-pressure air is generally used to blow the dust into the dust bag at a high speed in a short period of time to remove dust, resulting in dust bags The fiber gap of the bag mouth is frequently stressed, which increases the damage and replacement rate of the filter bag, and if the temperature drops and condensation occurs, a large amount of acid, alkali substances and hygroscopic dust will adhere to the bag mouth, and the long-term connection between the dust bag and the bag cage Rust or corrosion and bonding will occur, which not only affects the service life of the dust bag, increases production costs and production safety, but also limits the filter effect of the bag dust collector on dusty gas
