Waste gas treatment environment-friendly box

Abstract

The invention discloses an environment-friendly waste gas treatment box, which comprises an environment-friendly box main body, connecting pipes, flange discs and supporting cylinders, wherein the supporting cylinders are fixedly installed at the four corners of the lower surface of the environment-friendly box main body, the connecting pipes are fixedly arranged at the air inlet and the air outlet of the environment-friendly box main body, the flange disc is welded and fixed to the end of the connecting pipe, the outer surface of the connecting pipe is fixedly sleeved with a fixing ring, a round rod is rotatably arranged between the fixing ring and the flange disc through a bearing, a bolt is fixedly arranged at the end of the round rod, and the bolt penetrates through the outer surface of the flange disc. According to the invention, by arranging the round rod and the inner gear ring, the flange disc on the air pipe is aligned with the flange disc at the end of the connecting pipe, the handle rotates, the inner gear ring is in engaged connection with the outer gear ring, and the bolt at the end of the round rod and the flange disc at the end of the air pipe are driven to be screwed and fixed through threads, so that rapid disassembly and assembly of the air pipe are achieved, disassembly and assembly are easy and convenient and efficiency is high compared with the single screwing rotating bolt, and rapid installation of the air pipe and the environment-friendly box is facilitated.

Description

Technical field [0001] The invention belongs to the technical field of waste gas treatment, and specifically relates to an environmental protection box for waste gas treatment. Background technique [0002] The waste gas treatment environmental protection box is a device that pre-treats the waste gas generated in factories, workshops, etc. before being discharged to meet the national waste gas emission standards. The principles of industrial waste gas treatment include activated carbon adsorption, catalytic combustion, catalytic oxidation, and acid Various principles such as alkali neutralization, biological washing, and biological trickling filtration. [0003] The existing waste gas treatment environmental protection box has the problem that the air inlet and exhaust port of the environmental protection box are fixed and installed by flange bolts when connecting the air pipe. This connection method is troublesome to disassemble and assemble, and it is not convenient to disassembl...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an environmental protection box for exhaust gas treatment to solve the existing environmental protection box for waste gas treatment proposed in the above-mentioned background technology. When the air inlet and exhaust port of the environmental protection box are connected to the air pipe, they are fixed and installed by flange bolts. This connection method is more troublesome to disassemble and assemble, and it is not convenient for equipment disassembly and transportation.
