Vertical type wet process electric dust collector flow field optimizing device

Abstract

The invention discloses a vertical type wet process electric dust collector flow field optimizing device which comprises a dust collector shell body, a dust collecting pole plate and a venting channel, wherein the dust collector shell body is provided with an air inlet, an air outlet and a water outlet, the dust collecting pole plate is arranged inside the dust collector shell body, the venting channel is connected with the air outlet, an opening direction of an inlet end of the venting channel is downwards, and the central axis of the venting channel is coincident with the central axis of the air inlet. In use, flue gas entering from the air inlet is purified by the dust collecting pole plate, enters the venting channel through an inlet of the venting channel arranged on the same straight line with the air inlet, and then is discharged by the air outlet. By means of the process, the air outlet is connected with the venting channel, and an opening of the inlet end of the venting channel is opposite to the air inlet, namely the air inlet and the inlet of the venting channel are in the same straight line, so that air in the wet type electric dust collector flows in the vertical direction without deviating, thereby preventing air flow from impacting the dust collecting pole plate and preventing air flow from carrying sewage.

Description

technical field [0001] The invention relates to the technical field of electrostatic precipitator, in particular to a flow field optimization device for a vertical wet electrostatic precipitator. Background technique [0002] In cement, metallurgy, papermaking and other industries, there are a large amount of PM2.5 (refers to particles with a diameter less than or equal to 2.5 microns in the atmosphere, also known as inhalable particles) fine dust and some harmful gases in the flue gas generated during the production process. These flue gases are harmful to human health and have a great impact on the quality of the atmospheric environment. Wet electrostatic precipitator is one of the effective means to capture the above-mentioned flue gas. The working principle of the wet electrostatic precipitator is to form a layer of water film on the surface of the dust collecting plate by means of water spray or overflow water, etc., to wash away the dust deposited on the plate, so as ...

Problems solved by technology

However, the gas outlet 3 of the traditional vertical wet electrostatic precipitator is generally arranged on the side of the precipitator, which makes the air flow inside the precipitator deflect to one side during the circulation process, resulting in uneven gas distribution

In addition, when the horizontal air flow at the gas outlet 3 is large, it will impact the dust removal plate 5, causing it to shake, and will also take away the sewage inside the electrostatic precipitator, which will undoubtedly cause secondary pollution to the gas
