Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning system for an aeration device. Background Technology
[0002] After long-term operation, large molecular particles and activated sludge in membrane bioreactors tend to accumulate in the aeration pipes. This buildup clogs the pores of the aeration pipes, affecting aeration efficiency and significantly reducing oxygenation capacity and purging performance, leading to membrane fouling. Furthermore, obstructed airflow can increase the pressure differential of the blower, increasing its load. Prolonged operation of the blower under high load and high energy consumption reduces equipment lifespan, creates potential safety hazards, and increases operating costs. Traditional cleaning methods are time-consuming, expensive, and disrupt normal operation. Summary of the Invention
[0003] The present invention aims to address the shortcomings of the prior art by providing an aeration device cleaning system.
[0004] To achieve the above objectives, this utility model adopts the following technical solution:
[0005] A cleaning system for an aeration device includes a wastewater treatment tank, a ceramic flat sheet membrane, aeration pipes, a reagent tank, a blower, and an atomizer. A drain outlet is located at the lower part of one side wall of the wastewater treatment tank, and a wastewater inlet is located at the upper part of the side wall. The ceramic flat sheet membrane is installed inside the wastewater treatment tank, and an outlet pipe is connected to the ceramic flat sheet membrane. Several aeration pipes are located below the ceramic flat sheet membrane and are connected via gas pipes. A drain pipe is connected to the aeration pipes and extends to the drain outlet. The gas pipes are connected to the blower outside the wastewater treatment tank via an air inlet pipe. The reagent tank and the atomizer are connected via reagent pipelines, and the atomizer is connected to the air inlet pipe via an atomizer outlet pipe.
[0006] One end of the aeration pipe is connected to the gas pipe, and the other end of the aeration pipe is connected to the sewage pipe.
[0007] A liquid pump is connected to the aforementioned pharmaceutical pipeline.
[0008] The atomizer outlet pipe is connected to a first solenoid valve, and the atomizer outlet pipe is connected to the inlet pipe via a quick-connect fitting.
[0009] The portion of the sewage pipe extending from the sewage outlet is connected to a second solenoid valve.
[0010] The beneficial effects of this utility model are: after sludge is deposited on the aeration pipe, the liquid pump controls the addition of cleaning agent to assist the gas in cleaning the sludge in the aeration pipe. The cleaning agent is evenly atomized by the atomizer and carried into the aeration pipe by the gas, so as to fully contact the sludge in the aeration pipe and achieve high-efficiency decontamination.
