Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] like figure 1 As shown, the wet electrostatic precipitator of the present invention includes a tower body 1 and a pole plate area in the tower body 1. An insulator chamber 12 is arranged above the pole plate area to fix the broken end of the cathode wire suspension frame. A smoke uniform distribution plate 3 is arranged at the entrance of the smoke gas, and a plurality of through holes are arranged on the smoke gas uniform distribution plate 3. It is installed on the inner wall of the tower, which includes a pair of sub-ring plates that support each other, which can be welded on the inner wall of the tower to concentrate the airflow to the middle, increase the turbulence of the flue gas, optimize the flow field, promote local micro-mixing, and promote the flow of smoke. The fine particles carried by the air collide and condense to impr...

Abstract

The invention discloses a wet electric dust remover. The wet electric dust remover comprises a tower body and a polar plate area arranged in the tower body. An insulator chamber is arranged above thepolar plate area and used for fixing the broken end of a cathode wire suspension framework. The wet electric dust remover is characterized in that a flue gas even distribution plate is arranged at a flue gas inlet in the tower body, multiple penetrating through holes are formed in the flue gas even distribution plate, and a flue gas contraction ring is arranged above the flue gas even distributionplate; a spraying layer is arranged between the polar plate area and the flue gas even distribution plate; the polar plate area comprises anode plates and cathode wires; the anode plates and the cathode wires are wavy; and barbs are arranged on the crests and the troughs of the cathode wires and are located on the outward-protruding sides of the crests and the troughs. By means of the wavy polarplates, the turbulence degree of air flow between the plates is increased, a larger specific value area is achieved, a high dust removal effect can be achieved under the lower discharge voltage, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal, in particular to a wet electrostatic precipitator. Background technique [0002] my country's coal-based energy structure will not change for a long time. So far, the basic methods of pollutant control in thermal power plants in my country mainly include: low-nitrogen combustion + SCR denitrification + dry dust removal + wet desulfurization. The existing control methods have low capture efficiency for PM2. For GGH units, the phenomenon of "gypsum rain" or "blue / yellow smoke" often appears at the chimney outlet, causing secondary pollution to the environment. [0003] In order to solve these problems, under the current conditions of my country's electric power environmental protection, it is necessary to adopt the deep purification technology of smoke and dust to improve the efficiency of dust removal, so as to effectively remove fine particles, SO 3 and other pollutants.
