An electrostatic precipitator with a comb-toothed plate capable of blocking and diverting flow

Abstract

The invention discloses an electric dust remover with a comb-shaped plate capable of blocking and guiding flow. The electric dust remover comprises a housing, a smoke inlet, a smoke outlet, a plurality of electric fields, an upper comb-shaped plate, a lower comb-shaped plate and a dust hopper, wherein the smoke inlet is formed in the front end of the housing; the smoke outlet is formed in the rear end of the housing; the dust hopper is arranged at the bottom of the housing; the electric fields are hung in the housing; the upper comb-shaped plate and the lower comb-shaped plate are arranged on at least one part between the electric fields; the lower end of the lower comb-shaped plate is fixedly connected with a dust discharging plate of the dust hopper; the upper end of the lower comb-shaped plate is fixedly connected with the inner wall of the housing by virtue of a connection rod; the upper end of the upper comb-shaped plate is fixedly connected with the top surface of the interior of the housing; the lower end of the upper comb-shaped plate is fixedly connected with the inner wall of the housing by virtue of the connection rod. Compared with the prior art, the escape of smoke dust in the blind areas of the electric fields can be avoided; the airflow in the electric fields is relatively uniform; the dust removal efficiency of the dust remover is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of electric precipitators, in particular to the technical field of electric precipitators with comb-toothed plates capable of blocking and guiding flows. [0003] 【Background technique】 [0004] In recent years, the control of air pollution has attracted increasing attention from all over the world. As a country that is poor in oil, low in gas, and relatively rich in coal, China's coal resources account for 70% of the primary energy, and for a long period of time in the future, coal-fired power generation will still be the main source of my country's growing electricity demand. solution. However, coal has long been regarded as a "dirty energy source" globally. Especially in recent years, with the intensification of climate change and the increase of smog weather, public opinion has pointed the finger at coal, especially coal-fired power generation is accused of being the culprit of air pollution.

Problems solved by technology

However, due to the structural limitations of the dust collector itself, there are blind areas from the B.L line to the effective area of ​​the electric field and below the U.S line to the effective area of ​​the electric field.

When the dust-laden flue gas passes through the electric field, the dust in the two blind areas cannot be completely ionized and escapes directly, thus reducing the dust removal efficiency of the dust collector and making the air flow in the electric field more uneven
