Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a spray flushing structure for a wet electrostatic precipitator. Background Art

[0002] During the operation of the wet electrostatic precipitator, the nozzles in the spray flushing system are used to generate atomized water to form a water film on the surface of the anode tube. The sediment is removed by the downstream of the water film and the intermittent water flushing to achieve the purpose of dust removal and keep the anode tube and cathode line clean. During wet electrostatic flushing, the wet electrostatic power supply needs to be reduced or withdrawn to ensure the safety of the power supply and the inside of the wet electrostatic precipitator. In the existing wet electrostatic spray flushing system, the nozzle is directly connected to the bottom of the spray pipe. When the power supply is pressurized or shut down for flushing, the flushing water remaining in the spray main pipe will drip freely along the nozzle. The dripping water droplets are linear, forming a current between the spray pipe and the cathode hanging beam, which will not only cause the nozzle to burn out, but also cause the power supply to fail to start or boost quickly after flushing, resulting in substandard emission data.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN209452036U in the prior art discloses a spray flushing structure for a wet electrostatic precipitator, including a spray main pipe, a water outlet, a spray branch pipe and a high-pressure atomizing nozzle: the spray branch pipe is divided into a connecting section and a water spraying section, the connecting section of the spray branch pipe is connected to the spray main pipe through the water outlet, and the end of the water spraying section of the spray branch pipe is connected to the high-pressure atomizing nozzle: the angle between the axis of the connecting section of the spray branch pipe and the horizontal section of the spray main pipe is greater than 0 degree and less than 180 degrees.

[0004] Although the above-mentioned prior art solution can avoid the phenomenon of nozzle burning caused by short circuit, the end of the spray branch pipe is connected to the high-pressure atomizing nozzle, and the existing high-pressure atomizing nozzle is installed at the port of the pipe by bolts, nuts and gaskets. When disassembling and assembling, the staff needs to circle the nuts and bolts one by one to combine or separate the high-pressure atomizing nozzle, which makes it more cumbersome for the staff to inspect and maintain the high-pressure atomizing nozzle after a period of use. Disassembly and assembly are time-consuming, which increases the workload of the staff and affects the work efficiency. Utility Model Content
