Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a water washing tower used for sludge treatment. Background Art

[0002] The water scrubber is a necessary equipment in the oily sludge treatment process. Its main function is to desulfurize the gas produced after oxidizing, cracking and drying the oily sludge, and then use the water scrubber to wash and purify it, and finally discharge it into the atmosphere after deodorization.

[0003] The existing water scrubber is directly connected to the spray liquid recovery device, but in actual operation, reflux often occurs, which will cause incomplete replacement reaction when the spray liquid is replaced. At the same time, since a demister is often installed in the water scrubber, the existing demisters are mostly in the shape of wire mesh. If there is too much water vapor, the water droplets on the mesh will be connected into pieces, thus affecting the demisting effect.

[0004] For example, Chinese patent CN211936332U discloses a water washing tower for the treatment of oily sludge. A sealing section is added to the liquid outlet pipe of the spray liquid collector, and the U-tube principle is used to better isolate the inside of the shell from the spray liquid circulation system. At the same time, its demister is designed as a reasonable combination of an orifice plate, an upper fin plate and a lower fin plate. Water vapor will first touch the lower fin plate, part of the water vapor will directly condense and fall in contact with the back of the lower fin plate, and the other part will rise along the through holes on the orifice plate, contact with the upper fin plate, and then condense and fall along the upper fin plate, through the through holes, and finally along the lower fin plate into the collection hood.

[0005] However, when the device is in use, after the spray liquid flushes the waste gas, the impurities in the waste gas will circulate with the spray liquid, causing blockage of the pump body, thereby affecting the sludge waste gas treatment efficiency.

[0006] For this reason, we urgently need to provide a water washing tower for sludge treatment. Utility Model Content
