Bag dust removal system for hazardous waste industry

Abstract

The invention discloses a bag dust removal system for the hazardous waste industry. The bag dust removal system comprises a compressed air storage tank, an air filter, a pressure regulating device, apulse dust cleaning device, gas pipelines, a shell, filter bags and double-cover-plate heat-insulation devices. The compressed air storage tank, the air filter, the pressure regulating device and thepulse dust cleaning device are sequentially connected with one another by the gas pipelines, the pulse dust cleaning device is arranged in the shell, a perforated plate is arranged inside the shell, perforated plate holes are formed in the perforated plate, and openings of the filter bags are fixed to the perforated plate holes. The bag dust removal system has the advantages that the filter bags are made of PTFE (polytetrafluoroethylene) materials and are difficult to break, and accordingly dust removal medium requirements of the hazardous waste industry can be met; the pulse dust cleaning device comprises gas distribution tanks, pulse valves and blowing pipes, the pulse valves are submerged pulse valves and are high in gas output and low in resistance, and accordingly dust can be effectively cleaned for the filter bags; the double-cover-plate heat-insulation devices are arranged on the top of the shell and can effectively resist rain and snow scouring, and accordingly internal heat-insulation effects of the shell can be improved.

Description

technical field [0001] The invention relates to the technical field of dust removal systems, in particular to a bag dust removal system for the hazardous waste industry. Background technique [0002] Bag dust removal is the most widely used dust removal equipment. It is widely used in industrial dust removal, chimney dust removal and other places. It is also the most important equipment in dust removal engineering. Reach the pollutant discharge limit value promulgated by the State Environmental Protection Administration. With the stricter domestic smoke and dust emission standards, the European Union has promulgated the European Union (1992) standard and the European Union (2000 / 76 / EC) standard. The new standard is for particulate matter, acid gas and The control of heavy metal pollutants puts forward more stringent requirements. [0003] However, there are some problems in the use of bag filter in the hazardous waste industry, for example: 1. Most of the filter bags are ma...
