Abstract

The invention belongs to dust collecting equipment, and particularly relates to a bag type dust collector. A middle box (3) is fixedly arranged above a frame (12); an ash removing mechanism chassis (6) is fixed to the top end of the middle box (3); an ash removing mechanism (4) is arranged on the ash removing mechanism chassis (6); a plurality of vibrating mechanisms consisting of vertical shaft upper brackets (4-4) and vertical shaft lower brackets (4-5) are arranged on the ash removing mechanism (4); the ash removing mechanism (4) among the vibrating mechanisms is connected with a filter unit framework (7) in the middle box (3) through an upper hanging rod (17); a plurality of independent cloth bags (9) are connected below the filter unit framework (7) through cloth bag hanging chains (18); a filter head plate (15) is arranged below the connecting cloth bags (9); a plurality of filter head plate holes (15-1) are formed in the filter head plate (15) at equal intervals; the lower end of each independent cloth bag (9) is fixed in the filter head plate holes (15-1) through spring expansion rings; an ash hopper (1) is arranged on a frame (12) connected below the filter head plate (15). By adopting the bag type dust collector, the defects of short service lives of the cloth bags and high damage rate due to repeated curling of the cloth bags in mechanical vibrating ash removing are overcome.

Description

technical field [0001] The invention belongs to dust removal equipment, in particular to a bag type dust collector. Background technique [0002] With the rapid increase of industrial activities, smoke and dust pollution is becoming more and more serious. Particles with a diameter of less than 2.5 microns and more than 2.5 microns caused by industrial smoke and construction dust have become the main pollutants in my country at this stage. The haze weather is affecting people's lives. The large-scale smog weather has caused many consecutive traffic accidents. In major hospitals in the city, the number of patients admitted to departments of respiratory medicine and allergen testing has also soared several times. Therefore, in addition to large-scale pollution projects such as steelmaking and power generation that need to be treated, some Dust control in small steel kilns, non-ferrous metal smelting, special metal smelting, transfer stations, etc. is imminent. [0003] Most of t...

AI Technical Summary

Problems solved by technology

The dust cleaning method of mechanical vibration has the following disadvantages: (1) mechanical vibration dust removal makes the bag repeatedly twist and fold, resulting in shortened bag life and high damage rate; (2) mechanical vibration dust removal is a weak cleaning method. dust, which cannot be applied to the dust removal industry with small dust particle size and complicated working conditions; (3) The repeated bending and folding of the bag requires a large space between the bags, so the filter area of ​​the bag per unit volume is too small
