Online unblocking device for wet electrostatic precipitator nozzle

Abstract

The invention discloses an online unblocking device for a wet electrostatic precipitator nozzle. The online unblocking device comprises a pipeline, a first valve, a second valve and a venturi, wherein the first valve, the second valve and the venturi are arranged on the pipeline. The pipeline has a main and three branches; the free ends of the first and second branches gather and extend to form a nozzle opening used for mounting the nozzle; the free end of the third branch is provided with an unblocking outlet; the venturi is disposed at the connection of the first branch and the main; the first valve and the second valve are arranged on the second branch and the third branch respectively; the online unblocking device further comprises a pressure control system used for detecting pressure of the nozzle opening to control opening and closing of the valves. Automatic transition of the interior pressure and the operating statuses of the valves is controlled without stopping a furnace, thus the nozzle is automatically unblocked; meanwhile, after unblocking, adjusting is automatically performed to allow the nozzle to continue to run. Compared with the traditional unblocking methods, the online unblocking device has the advantages that the performance of a wet electrostatic precipitator is enhanced and the benefit of the wet electrostatic precipitator is greatly improved.

Description

technical field [0001] The invention relates to a device for cleaning nozzles, in particular to an online cleaning device for wet electrostatic precipitator nozzles. Background technique [0002] At present, the wet electrostatic precipitator is a new dust removal equipment used to deal with trace dust and fine particles. It is mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM2.5 and other harmful It is an ideal equipment for controlling air dust pollution. However, at present, the spray nozzles of some wet electrostatic precipitators are all installed inside the wet electrostatic precipitator. When the furnace is not in operation, the interior is full of flue gas, which cannot be entered manually, so the furnace can only be shut down for manual cleaning, which affects production efficiency; and There are problems such as time-consuming and labor-intensive, low efficiency, and unsatisfactory cleaning by manual cleaning.
