Low-pressure online long-bag pulse bag dust collector

Abstract

The invention discloses a low-pressure online long-bag pulse bag dust collector. The dust collector is formed by a shell, an ash hopper assembly, a filter bag assembly and a pulse jetting assembly, flue gas enters the shell from an air inlet in the left sidewall of the shell, large particles first fall into the ash hopper assembly, small particles and the flue gas are deacidified by a high temperature generated by the ash hopper assembly, and then upwards flow into the filter bag assembly, are filtered by the filter bag assembly, and are accumulated on the inner wall of the filter bag assembly, the pulse jetting assembly is turned on, the pulse jetting assembly is formed by a gas storage tank, a blowing tube, nozzles and a pulse valve, and the pulse valve is turned on to make compressed air in the gas storage tank released into the blowing tube and jetted into the filter bag assembly through the nozzles, so vibration generated by the expansion of the filter bag assembly and reverse airflow make dusts adhered to the surface of a filter bag disengage from the filter bag assembly and fall into the ash hopper assembly in order to prevent secondary adsorption and reduce the resistance of the dust collector, thereby the service life of the filter bag is prolonged.

Description

Technical field [0001] The invention relates to the technical field of waste incineration, in particular to a low-voltage online long bag pulse bag type dust removal device. Background technique [0002] After the solid waste is incinerated in the incinerator, the toxic and harmful substances are decomposed into non-toxic and harmless compounds, so as to quickly realize the harmless treatment of the fixed waste, but the incineration of the solid waste will produce tail gas with a large number of particles. [0003] In the existing stationary waste incineration system, an exhaust dust removal device is installed at the tail to collect dust. However, after the bag filter is used for a period of time, due to the effects of filtering, collision, and static electricity, the surface of the filter bag will be affected. Accumulation of powder layers, these powder layers are highly corrosive, and block the filter bag, which will cause the problem of shortening the life of the filter bag. S...

Problems solved by technology

[0003] In the existing fixed waste incineration treatment system, the tail gas dedusting device is installed at the end to collect dust. However, after the bag filter is used for a period of time, due to the effects of screening, collision and static electricity, the surface of the filter bag will be damaged. Accumulation of dust layers, which are highly corrosive, as well as clogging of filter bags, can cause problems in shortening the life cycle of filter bags
