Multipoint centralized dedusting desulphurization denitration apparatus

Abstract

The invention relates to a multipoint centralized dedusting desulphurization denitration apparatus. According to the invention, a cylindrical shell is arranged, a cover plate is arranged at the top of the cylindrical shell, a dust discharging port is arranged at the bottom of the cylindrical shell, a loop of air inlets is arranged on the upper part of the cylindrical shell, an air inlet pipe which is tangent to the cylinder wall of the cylindrical shell is arranged at the air inlets, the air inlet pipe is connected with a tail gas discharge pipe through a bend pipe arranged towards, a spray nozzle I for sprinkling desulphurization denitration liquid is arranged on the upper part of the bend pipe, a guide shell is arranged at the bottom of the cover plate, a lower end of the guide shell is arranged in the cylindrical shell which keeps 40-60 cm from the lower part of the air inlet to the air inlet, several air outlets communicated to the guide shell are arranged on the cover plate, and the caliber of the air outlet is greater than the caliber of the air inlet. According to the invention, the bend pipe is arranged at the outboard of the air inlet of the cylindrical shell, desulphurization and denitration are carried out in the bend pipe, waste water after desulphurization and denitration is discharged from the dust discharging port along the side wall of the cylindrical shell, then desulphurization and denitration are carried out on the tail gas, dust accumulated on the inner wall of the cylindrical shell is cleaned, several air inlets and air outlets are arranged, spraying resistance is overcome, and the air inlet speed is accelerated.

Description

technical field [0001] The invention relates to a tail gas treatment device, in particular to a multi-point centralized dust removal, desulfurization and denitrification device. Background technique [0002] In the existing industrial production process, dust collectors are mainly used to remove dust and some coarse particles in the tail gas, but since the main pollutants in the tail gas also include nitrogen oxides, sulfur dioxide and hydrocarbons, these gases cannot be collected The dust collector is separated from the air, and it is easy to discharge into the atmosphere with the exhaust gas after dust removal, causing photochemical smog and causing sulfur and nitrogen pollution in the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-point centralized dust removal, desulfurization and denitrification device with reasonable design and convenient use for the deficiencies of the prior art.
