Desulfurization-denitration purification tower for flue gas

Abstract

The invention provides a desulfurization-denitration purification tower for flue gas. The desulfurization-denitration purification tower for flue gas comprises a purification tower. The outer side surface of the bottom of the purification tower is connected with a discharge pipe; the part, close to a central position, of the outer side surface of the purification tower communicates with two L-shaped tubes arranged in parallel; the other end of one of the L-shaped tubes is connected with a liquid feeding funnel; two parallel filter screens are arranged inside the purification tower at a position near the center of the tower; the two filter screens are rotatably connected to the inner side surface of the purification tower through a rotating shaft; one end of the rotating shaft penetrates the side surface of the purification tower and is connected with belt pulleys; the two belt pulleys are in transmission connection via a belt; the outer side walls of one of the filter screens is equipped with a rotary snapping mechanism; and the rotary snapping mechanism includes a U-shaped snapping bar, a spring and a rotating tube. The desulfurization-denitration purification tower for flue gas provided by the invention has improved safety, does not need manual disassembling of the filter screens for regular cleaning, realizes the rotation operation of the filter screens via rotary snapping mechanism, and is simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of desulfurization and denitration purification towers, in particular to a flue gas desulfurization and denitration purification tower. Background technique [0002] The exhaust gas purification tower is a device that is equipped with different chemicals according to different exhaust gases and uses wet treatment to purify a variety of toxic and harmful exhaust gases. It is designed by absorbing the essence of purification technologies such as foam tower, spray tower, packing tower, etc., and has the effect of dust removal. [0003] The flue gas discharged from production and processing contains not only sulfur compounds, nitrate compounds, but also dust. The dust needs to be treated inside the desulfurization and denitrification purification tower. The dust can also be treated by spraying the reaction solution of sulfur compounds and nitrate compounds, so that the dust Accumulated on the filter screen inst...

Problems solved by technology

[0003] The flue gas discharged from production and processing contains not only sulfur compounds, nitrate compounds, but also dust. The dust needs to be treated inside the desulfurization and denitrification purification tower. The dust can also be treated by spraying the reaction solution of sulfur compounds and nitrate compounds, so that the dust Accumulated on the filter screen installed inside the purification tower, the dust connected to the filter screen needs to be disassembled regularly. Since the purification tower contains some harmful gases, manual operation is required for disassembly, which is safe and the disassembly process is cumbersome
