Compartmental static normal-pressure type pulse bag type dust remover

Abstract

The invention relates to a compartmental static normal-pressure type pulse bag type dust remover with high utilization rate of energy resources and low production and operation cost, which comprises a plurality of dust removal box bodies, wherein each dust removal box body comprises an upper box body, a middle box body and a lower box body, the upper parts of the upper box bodies are provided with air outlets, each upper box body and each middle box body are separated by a partition plate, the joints of the upper box bodies and the middle box bodies are fixedly connected with porous plates, filter bag frameworks are arranged at the position of the open holes of the porous plates, the outsides of the filter bag frameworks are sleeved and connected with filter bags, spraying and blowing pipes are arranged above the porous plates, gas bags are connected on the spraying and blowing pipes, the end parts of the spraying and blowing pipes are connected with pulse valves, the outer sides of the dust removal box bodies are provided with air inlet pipelines, the joints of the air inlet pipelines and the lower box bodies of all dust removal box bodies are provided with air inlet valves, the bottom end of each lower box body is provided with an ash discharging valve, the lower parts of the external surfaces of the lower box bodies are fixedly connected with brackets, and intelligent control instruments are connected on the dust removal box bodies and respectively control the air inlet valve, the pulse valve and the ash discharging valve in each dust removal box body.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to a chamber-divided static and normal-pressure pulse bag dust collector. Background technique [0002] The cleaning and blowing of the currently used blowing bag filter is to blow the positive pressure air, back pressure blowing and spray each filter bag in the same dust removal box, while the filter bag is still filtering. That is to say, dust cleaning and filtration are mixed in the same dust removal box at the same time. The cleaned dust will fly up again, and some of it will be collected by the adjacent filter bag, causing the filter bag to absorb dust for the second time. The dust is not completely removed, and the filter bag The reduction of the ventilation volume leads to low dust removal efficiency. The blowing and dust cleaning is to supply air under positive pressure. In the case of reverse pressure blowing, the blowing air pressure is high. If the blowing air pressur...
