Maintenance and maintenance of wet scrubber
Maintenance and maintenance of the scrubber: firstly check whether the packing layer and nozzles are blocked, secondly check whether the liquid level of the water tank is high enough to meet the liquid level requirements of the circulating pump, prevent the circulating pump from idling, and finally check the thickness of the sediment at the bottom of the spray tower water tank. The maintenance and maintenance of the leaching tower need to be cleaned in time This article mainly explains the maintenance and maintenance methods of the spray tower. The PP scrubber is a kind of wet waste gas treatment device. It adopts the counter-current principle. The waste gas passes through the spray tower and is dosed into the bottom water tank. The circulating fluid is sprayed on the packing layer. In contact with exhaust gas, neutralization and absorption reaction occurs to achieve the purpose of purifying exhaust gas. Then a complete set of wet scrubbers includes the tower body, water tank, packing layer, nozzle, demister layer, circulating pump, pipeline, pressure gauge, and feeder. Drainage pipes and the spray tower system are relatively negative pressure. During the operation, the maintenance and maintenance of the wet scrubber are equally important, which is directly related to the efficiency of waste gas treatment and the stability of the system. So what does the environmental protection engineering company need to do after the factory takes over a set of stable running spray tower systems? Xicheng Environmental Protection gives the following suggestions: The following items of the spray tower should be checked regularly during use. Whether the appearance of the PP scrubber has serious dirt, debris, etc.; Whether the multi-faceted hollow ball packing and nozzles in the PP scrubber are blocked; Whether the circulating spray pump is operating normally, observe the pressure gauge parameters; Whether the inside of the circulating water tank is blocked, observe the water level inside and outside the filter; Whether the sediment at the bottom of the water tank is too thick; Whether the screw fixing parts are loose or abnormal noise during operation; Regularly check and record the above content. If problems are found, it is recommended to enter the spray tower for maintenance and repair operations according to the following methods. Maintenance of PP scrubber Clean the surface of the wet scrubber and the surface of the water pump, fan, and ventilation pipe to prevent accumulation of debris; If it is found that the packing layer and nozzles in the wet scrubber are clogged, it is recommended to close the water supply ball valve of one spray layer to make the water pressure of the circulating water pump all pressurize the spray layer of the other layer. The ball is flushed and cleaned. After clearing the blockage, replace it with another spray layer for scouring and cleaning. If the blockage is serious and cannot be cleaned by its own water pressure, it can be solved by replacing the blocked spiral nozzle; If the water pump appears idling, abnormal noise, etc., it should be shut down for maintenance in time. The idling of the water pump is generally because the water level of the water tank is too low, and the water inlet ball valve should be opened to supplement the circulating water. For abnormal noise, loosening, etc., the specific cause should be found and repaired, and normal operation can be performed after recovery; Open the circulating water tank cover, you can see multiple filter orifice plates in the water tank. If you find that there are many stains on the top and the mesh is blocked, please take it out and scrub it with a brush, and then put it back in the tower. The too serious blockage should be cleaned with warm water or with chemicals; The sediment at the bottom of the spray tower should be cleaned regularly. Drain the sewage in the wet scrubber, open the transparent inspection hole, and enter the tower to clear the sediment out of the tower with tools, and then rinse the bottom and walls of the tower with clean water. If there are serious stains in the tower and the circulating water tank, use the corresponding agent to clean it; If the wet scrubber is loose, abnormal noise, etc. during the operation, the cause should be found in time, reinforced, or replaced by the corresponding parts.
