Problems solved by technology

[0005] The cathode flushing layer and the anode flushing layer are arranged alternately, and both of them have several partitions, resulting in cumbersome pipeline layout; more importantly, when the number and layers of pipelines increase, it is easy to interfere with the high-voltage power supply of the cathode line , thus causing potential safety hazards of discharge and short circuit
[0006] In addition, when the cathode flushing layer and the anode flushing layer are arranged staggered up and down, it is not conducive to the full use of spray water. Most of the spray water sprayed by the upper nozzle will be blocked by the lower spray pipe, which reduces the spray pressure and is not conducive to cleaning. Ash

Embodiment Construction

[0028] The core of the present invention is to provide a spraying system of a wet electrostatic precipitator, which can realize a reasonable arrangement of spraying pipelines, ensure efficient dust removal, and ensure a safe discharge distance.

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can accurately understand the technical solution of the present invention.

[0030] The up and down in the present invention are defined with reference to the use state of the wet electrostatic precipitator: when the wet electrostatic precipitator is placed normally, the vertical direction is the direction perpendicular to the ground, and in the vertical direction, the direction close to the ground is the downward direction, away from The direction of the ground is upward; a plane parallel to the ground is defined as a horizontal plane; in the horizontal plane, the direction in which each spray ...

Abstract

The invention provides a wet electrostatic precipitator and a spray system thereof, which can realize reasonable arrangement of spray pipelines and ensure a safe discharge distance. The wet electrostatic precipitator includes several electric field partitions, and the spray system includes several spray devices corresponding to the electric field partitions. The spray devices include a spray main pipe and several spray branch pipes connected thereto. A plurality of anode tubes are arranged in the electric field partition, and a cathode line runs through each of the anode tubes, and each of the spray branch tubes is arranged at intervals from left to right on the top of each of the anode tubes, and is spaced apart in the respective extension directions. Several nozzles are provided, and the spraying areas of adjacent nozzles partially overlap to fully cover the top surface of the anode tube. The present invention adopts the anode tube and connects the cathode line through the anode tube, so that the anode tube and the cathode line can be sprayed synchronously, the arrangement of the spray pipeline is simplified, the safe discharge distance is sufficient, and the spray area can be fully covered The top surface of the anode tube has high spray reliability.

Description

technical field [0001] The invention relates to the technical field of wet electrostatic precipitators, in particular to a wet electrostatic precipitator and a spraying system thereof. Background technique [0002] Wet electrostatic precipitator is a kind of dust removal equipment used to deal with trace dust and fine particles. It can be divided into cross flow type (horizontal type) and vertical flow type (vertical type). The cross flow type is mostly plate structure, and the gas flow direction is horizontal direction. In and out; the vertical flow type is mostly a tubular structure, and the gas flow direction is vertical in and out. [0003] Patent No. 201410482256.0 discloses an intermittent spray flushing system and method for a vertical flow wet electrostatic precipitator, including a cathode flushing layer and an anode flushing layer arranged staggered up and down, and the anode flushing layer and the cathode flushing layer respectively include multiple partitions , ...
