Cleaning device and method for cleaning cooler of desulfurization system
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. 1.
