Double-rotation dust mist purification device

Abstract

The invention discloses a double-rotation dust mist purification device. The double-rotation dust mist purification device comprises a housing and absorption cylinders, an upper patterned plate and alower patterned plate are arranged in the shell up and down at a certain interval; a flue communicating with the interior of the shell is arranged at the lower part of the shell; the absorption cylinder is of a cylindrical shell structure. A plurality of absorption cylinders are fixed between the upper patterned plate and the lower patterned plate; air outlet holes communicating with the absorption cylinders are formed in the upper patterned plate; a plurality of rotational flow holes tangent to the side wall of each absorption cylinder are formed in the lower part of the side wall of the absorption cylinder; air inlet holes communicating with the rotational flow holes are formed in the lower patterned plate, a rotational flow column with the upper end and the lower end fixed to the upperpatterned plate and the lower patterned plate respectively is arranged in each absorption cylinder, flow guide blades are fixed to the outer surface of each rotational flow column, the spiral mode ofthe flow guide blades is an Archimedes spiral from bottom to top, and an atomization nozzle is arranged below the lower patterned plate. The invention aims to provide the double-rotation dust mist purification device, a double-rotation mode is adopted, supersaturated flue gas forms strong external rotation ascending gas flow in the absorption cylinders through the rotational flow holes and the rotational flow columns, and centrifugal purification is carried out.

Description

technical field [0001] The invention relates to the technical field of dust mist purification, in particular to a double-rotation dust mist purification device. Background technique [0002] Wet dust removal is a method of cleaning the gas by fully contacting the cleaning liquid (usually water) with the dust-containing gas to wash down the dust particles. This dust removal method has a simple structure and low cost, and is especially suitable for handling high-temperature, high-humidity, flammable, and explosive dust-containing gases. It is widely used in air pollution control and gas purification in various departments of industrial production. [0003] Compared with high-efficiency dust collectors such as bag filter and electrostatic precipitator (including wet electrostatic precipitator), the dust removal efficiency of existing wet dust removal (mist removal) equipment is relatively low. [0004] In order to overcome the above-mentioned technical defects, Shi Ling, Xiang...
