Efficiency Improvement Device of Vertical Flow Wet Electrostatic Precipitator

Abstract

The invention provides a device for improving the efficiency of a vertical-flow wet electrostatic dust remover. The device is used for improving the distribution uniforming effect of a flow field in the body of the electrostatic dust remover, reducing the number of short flue gas flow regions and enhancing the dust removal efficiency of the electrostatic dust remover. A gas flow distribution uniforming plate is adopted according to the distribution characteristic of the gas flow at the entrance of an electric field so that the gas flow can be distributed uniformly in the electric field and the flow field can be optimized. In addition, due to the additional arrangement of internal components including a flow stop ring plate, a flow stop plate, a flow guide ring plate and a flow collection tank, the number of short flue gas flow regions in the electric field can be reduced. The device provided by the invention has the advantages that the additionally arranged internal components are easy to manufacture and are easy to install, increase of resistance to a system is small, the flow filed in the electric field can be distributed uniformly, the number of short flue gas flow regions can be reduced, the flue gas can be charged uniformly, a small amount of flue gas can escape, and the purpose of removing dust efficiently can be achieved.

Description

technical field [0001] The invention relates to the field of electric dust removal, in particular to an efficiency raising device for a vertical flow wet electric dust collector. Background technique [0002] The rapid development of modern industry not only brings convenience to human beings, but also brings serious environmental pollution. Air pollution is the main issue in various environmental pollution, and the pollutants produced by coal-fired power plants and industrial boilers are atmospheric environmental pollution. main source of . As the country pays more and more attention to environmental protection, fine dust, SO 3 The emission reduction of acid mist, mercury and other pollutants in the form of aerosols has been put on the agenda. At the same time, the new national "Ambient Air Quality Standards" includes PM2.5 into the ambient air quality standards. Therefore, how to effectively reduce fly ash fine particles, gypsum fine particles and SO 3 The impact on the...

Problems solved by technology

In the electric field section, due to the discharge of the cathode line, the PM2.5 fine dust and aerosols contained in the flue gas are charged and captured by the anode plate under the action of the electric field; but the conventional vertical flow wet electrostatic precipitator (such as Figure 4 , 9 ) In order to ensure the discharge safety of the cathode line and the tower wall, the cathode line and the anode plate are not installed near the tower wall and the electric field partition channel. It is inevitable that there will be a small area near the tower wall and the area in the electric field partition channel. However, in order to ensure and improve the dust removal efficiency, it is necessary to reduce the amount of flue gas escaping from this part of the area.
