High-pressure wet-type demisting dust remover

Abstract

The invention discloses a high-pressure wet type demisting dust remover, which comprises a box, a flushing mechanism, an electric dust removal mechanism and an air uniformizing structure, wherein theflushing mechanism and the electric dust removal mechanism are arranged in the box, the air uniformizing structure comprises a fixed air uniformizing plate and a floating air uniformizing plate whichis arranged above the fixed air uniformizing plate and floats up and down along with airflow to adjust the height of a flow uniformizing layer, the numbers of air holes in unit area on the floating air uniformizing plate are the same, the density of the air holes formed in the first plate surface of the fixed air uniformizing plate is greater than that of the second plate surface, the first platesurface is located on one side of the center line of the fixed air uniformizing plate and close to an air inlet, the second plate surface is located on the other side of the center line of the fixed air uniformizing plate and away from the air inlet, the an air uniformizing structure is arranged in a lower air chamber, air is uniformized twice through the fixed air uniformizing plate and the floating air uniformizing plate of the air uniformizing structure, in order to guarantee the air uniformizing effect, the density of the air holes in the first plate surface is larger than that of the airholes in the second plate surface, and in order to further guarantee the air uniformizing effect, inclined air holes are further formed in the first and second plate surfaces.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a high-pressure wet mist and dust remover. Background technique [0002] The working principle of the electrostatic precipitator is to use the high-voltage DC uneven electric field to ionize the gas molecules in the flue gas, generate a large number of electrons and ions, move to the poles under the action of the electric field force, and encounter the dust particles in the air flow during the movement. It is charged, and the charged dust is separated from the airflow under the action of the electric field force and moves to the polar plate or polar line with the opposite polarity. When the charged dust reaches the polar plate or polar line, it is adsorbed on the polar plate or polar line by electrostatic force, thus To purify the gas. [0003] The existing high-pressure wet demister dust collector has incomplete dust removal and mist removal, and excessive sedime...

AI Technical Summary

Problems solved by technology

[0003] The existing high-pressure wet demister dust collector has incomplete dust removal and mist removal, and excessive sedimentation inside some sedimentation pole tubes and only a small amount of sedimentation inside some sedimentation pole tubes, which increases the frequency of cleaning the sedimentation pole tubes. The reason lies in the exhaust gas When it is passed through, it is not evenly flowed, so that part of the sedimentation pole tube passes too much exhaust gas per unit time, while the other part of the sedimentation pole tube passes too little exhaust gas, such as a wet dust collector disclosed by the publication number: CN109772586A, There is no corresponding solution to the above problems, and because the exhaust gas purification time is not extended, the purification effect is not ideal
