Cleaning device and method for cleaning cooler of desulfurization system

Abstract

The invention discloses a cleaning device and method for cleaning a cooler of a desulfurization system. The cleaning device comprises an upper covering plate, a lower covering plate, a liquid storing groove, a cleaning pump, a first cleaning pipeline, a second cleaning pipeline, a steam heating device, a steam pipeline, and a sewage pipeline. The upper covering plate and the lower covering plate are used for sealing the upper and lower ends of the cooler to be cleaned; a cleaning liquid inlet, a cleaning liquid outlet and a steam inlet are formed in the upper covering plate, and a sewage outlet is formed in the lower covering plate. The liquid storing groove is used for storing the cleaning liquid. The cleaning pump is used for pumping the cleaning liquid and is connected to the liquid storing groove. The first cleaning pipeline and the second cleaning pipeline are respectively used for connecting the cleaning pump and the cleaning liquid inlet, and the cleaning liquid outlet and the liquid storing groove so as to form a cleaning liquid circulating loop. The steam heating device is used for producing steam. The steam pipeline is used for connecting the steam heating device and the steam inlet. The sewage pipeline is connected to the sewage outlet and is provided with a switching valve. The cleaning device has the advantages that labor investment in the cleaning process is reduced, and fine cleaning effect can be achieved.

Description

technical field [0001] The invention relates to a cleaning process for a desulfurization system, in particular to a cleaning device and method for cleaning a cooler of a desulfurization system. Background technique [0002] In the "ionic liquid" type desulfurization system, due to the characteristics of the production process and absorbent, powdery solid sulfur will be produced in the desulfurization system, and these powdery sulfur will adhere to the screen of the cooler of the desulfurization system, causing cooler Blockage, thereby reducing the cooling effect of the cooler. Therefore, the cooler needs to be cleaned regularly to remove the sulfur stuck in the cooler screen to ensure the cooling effect. [0003] At present, the usual cleaning method is to remove the top head of the cooler, then take out the screen inside it, and place it on the ground for manual cleaning. Because the mesh of the screen is thin and the gaps between the mesh are dense, if the water pressure...

AI Technical Summary

Problems solved by technology

Because the mesh of the screen is thin and the gaps between the mesh are dense, if the water pressure is not properly controlled during manual cleaning, it will easily cause the mesh to be washed and deformed, which will affect the cooling effect and service life of the cooler, and affect the normal production.

In addition, manual cleaning takes a long time to clean, requires a lot of labor, and the cleaning effect is relatively poor, which not only increases the workload, but also makes it difficult to guarantee the cleaning effect, which may reduce the cooling effect of the cooler.
