Automatically-rotating flusher for wet desulfurization demister

Abstract

The invention discloses an automatically-rotating flusher for a wet desulfurization demister. The flusher comprises a vertical shaft tube and a rotary sprinkler, wherein the rotary sprinkler comprises a middle round driving box body and spray tubes symmetrically connected around the driving box body; at least two spray tubes are arranged; spray holes or spraying devices are uniformly distributed below the spray tubes; the free ends of the spray tubes are enclosed; the vertical shaft tube is arranged in the middle of the lower wall of the driving box body through a bearing; the inner surface of the upper wall or lower wall of the driving box body is provided with a certain number of projecting rotary raised lines which rotate leftwards or rightwards; and the spray tubes are tangentially arranged along the cylindrical surface of the round driving box body and the rotation directions of the spray tubes are matched with those of the rotary raised lines in the box body. The device has the advantages of simple structure, clean flushing and automatic rotation function. If roller guide rail supports and auxiliary driving mechanisms are arranged at the two ends of the spray tubes, rotation of the flusher can be further ensured.

Description

1. Technical field [0001] The invention relates to an auxiliary part of a power plant flue gas wet desulfurization demister, in particular to an automatic rotary flushing device for a wet desulfurization demister. 2. Background technology [0002] At present, most of the flushing devices in the wet desulfurization demisters of power plants are fixed pipe network spraying structures. By setting a flat pipe network above and below the demister, and opening spray holes or installing spray Spray water directly on the demister through the pipe network on a regular basis to wash away the adhered objects on the demister. [0003] This type of flushing is prone to flushing blind areas during long-term use. The flushing position is basically determined, and other areas that are not in the spray hole or the corresponding part of the sprinkler cannot be flushed. When flushing, a large impact force will be generated, and part of the pipe network will be broken due to the impact force, ...

Problems solved by technology

[0003] This type of flushing is prone to flushing blind areas during long-term use, and its flushing position is basically determined, and other areas that are not in the spray hole or the corresponding part of the sprinkler cannot be flushed clean, and due to the need for relatively high water pressure, when it is opened regularly When flushing, a large impact force will be generated, and part of the pipe network will be broken due to the impact force, which will affect the use of the entire equipment, waste a lot of maintenance time, and affect the entire power generation process
