Wet electric precipitator flushing system and method

Abstract

The invention belongs to the field of wet electric precipitator flushing, and provides a wet electric precipitator flushing system and method. In order to solve the problems of high cost and poor flushing effect of the existing wet electric dust collector flushing system, the flushing system provided by the invention only comprises one set of flushing pipe network and is arranged in a wet electricdust collector, wherein the flushing pipe network is arranged below a wet type electric precipitation cathode support beam and above a wet type electric precipitation anode support beam, and is composed of a main flushing pipe and a plurality of branch flushing pipes communicated with the main flushing pipe, flushing nozzles are evenly arranged on each branch flushing pipe at intervals, the flushing main pipe is arranged along the anode supporting beam, the branch flushing pipes are horizontally arranged along a flower plate on an anode, and the flushing nozzles are vertically and upwards mounted and are used for uniformly spraying flushing water on the wet-removing cross section. During formal operation, dripping holes of the anode washing pipe cannot be blocked, so that the waste of maintenance cost and operation cost is avoided.

Description

technical field [0001] The invention belongs to the field of wet electrostatic precipitator flushing, in particular to a wet electric dust collector flushing system and method thereof. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The high-efficiency water-free wet electrostatic precipitator cleans the dust by washing the surface of the dust collection electrode and discharge electrode with water film. The high-efficiency anhydrous wet electrostatic precipitator is equipped with two layers of flushing pipe network: cathode flushing pipe network and anode flushing pipe network. The flushing pipe network is mainly used for flushing before starting up and after shutting down, and regularly flushing during normal operation, and the flushing frequency is once every two weeks. Both cathode and anode flushing are carried out by setting electr...

AI Technical Summary

Problems solved by technology

[0004] The inventor found through the actual operation of several projects that have been put into operation and the actual investigation that the cathode and anode flushing system of the high-efficiency anhydrous wet electrostatic precipitator has a good effect when it is first put into operation, but with the extension of the operation time, the self-wet absorption Adhesive liquid droplets entrained in the flue gas from the tower will slowly accumulate on the anode pipe network and solidify and precipitate, resulting in the blockage of the drip hole of the anode pipe network and the loss of the flushing effect and the setting significance of the anode flushing pipe network, resulting in equipment investment , Operation and maintenance investment waste
