Purification and dust removal device

Abstract

The invention provides a purification and dust removal device. A plurality of dust suction pipes are vertically distributed in a box body of the purification and dust removal device; cathode lines penetrate through the dust suction pipes respectively and are fixed by an upper frame and a lower frame; the upper end parts of the cathode lines are fixed on the upper frame, and the lower end parts of the cathode lines are fixed on the lower frame; the upper frame and the lower frame are both fixed on the box body; the upper frame or the lower frame is connected with a high-voltage power supply system through a wire. The dust suction pipes are arranged to greatly enlarge the dust collection area; the cathode lines penetrate through the centers of the dust suction pipes, so that the internal part of each dust suction pipe forms a high electric field which is uniform in strength, large in onset area, and capable of rectifying the exhaust gas when the exhaust gas passes through each of the dust suction pipes; the cathode lines are fixed through elastic elements, so that the cathode lines can be tensioned tightly; the elastic elements are low in wind resistance and low in possibility of swing, so that the cathode lines are better in stability.

Description

【Technical field】 [0001] The invention relates to the field of printing and dyeing industry, in particular to a purification and dust removal device for treating waste gas. 【Background technique】 [0002] The printing and dyeing industry will produce a large amount of waste gas during the production process. If these waste gases are directly discharged into the atmosphere, they will cause serious pollution to the atmospheric environment, especially the waste gas from the setting machine, which contains oil mist, fibers, water vapor, dust and SO 2 , N 2 o X and other harmful gases, therefore, the waste gas must be purified. [0003] The invention patent with the publication number of 103817005A and the publication date of 2014-05-28 "A Plate-Tube Vertical Flow Wet High-Efficiency Electrostatic Precipitator" discloses a plate-tube vertical flow wet-type high-efficiency electrostatic precipitator, including the shell, which is characterized in that The housing is provided wi...
