Environmental-protection treatment equipment

Abstract

The invention discloses environmental-protection treatment equipment. The environmental-protection treatment equipment comprises a rotary furnace, a cooling screener connected with a furnace port of the rotary furnace, and dust removing equipment connected with an exhaust port of the rotary furnace; the rotary furnace is arranged in a closed building; the closed building is provided with an opening; a connecting pipe is arranged between the rotary furnace and the cooling screener; the connecting pipe comprises a feed pipe and a discharge pipe laminated and layered up and down; the bottom of the discharge pipe is of a netty structure; the feed pipe and the discharge pipe both adopt downward inclined structures; feed ports of the feed pipe and the discharge pipe are downwards inclined to discharge ports; the discharge port of the feed pipe is arranged at the end near the rotary furnace; the feed port of the feed pipe extends outside the closed building; the feed port of the discharge pipe is arranged at the end near the rotary furnace; the discharge port of the discharge pipe is arranged at the end near the cooling screener; and a molten aluminum collecting box is arranged at the bottom of the discharge pipe.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an environmental protection treatment equipment. Background technique [0002] Due to the relative lack of high-quality aluminum ore resources in my country, only Shanxi, Guangxi, Guizhou, Henan and Jiangxi have relatively rich bauxite ore. The production of aluminum metal from alumina consumes a lot of energy and the process is complicated, and the production of electrolytic aluminum metal is still slow It cannot meet the ever-growing construction and development requirements, so aluminum resources in some places are mainly obtained from recycled waste aluminum, which includes pure aluminum scraps from aluminum processing enterprises, deformed aluminum alloys from old buildings on construction sites, casting Aluminum alloys, aluminum core wires and waste aluminum products, etc. In the process of refining pure aluminum or aluminum alloys from waste aluminum, alumin...

[0002] Due to the relative lack of high-quality aluminum ore resources in my country, only Shanxi, Guangxi, Guizhou, Henan and Jiangxi have relatively rich bauxite ore. The production of aluminum metal from alumina consumes a lot of energy and the process is complicated, and the production of electrolytic aluminum metal is still slow It cannot meet the ever-growing construction and development requirements, so aluminum resources in some places are mainly obtained from recycled waste aluminum, which includes pure aluminum scraps from aluminum processing enterprises, deformed aluminum alloys from old buildings on construction sites, casting Aluminum alloys, aluminum core wires and waste aluminum products, etc. In the process of refining pure aluminum or aluminum alloys from waste aluminum, aluminum ash and waste gas containing dust particles will be generated, and this part of aluminum ash and waste gas containing dust particles needs to be treated for environmental protection Only after treatment can it be discharged into nature. There are various deficiencies in the existing environmental protection treatment equipment, such as failure to meet emission standards or low degree of equipment automation.
