[0002] In the process of waste gas treatment, the corresponding desulfurization washing tower is generally used to spray and reduce dust on the waste gas, so as to quickly remove impurities in the waste gas. When the washing tower is in use, the corresponding drainage pump is required to discharge excess liquid.

[0003] At present, the drainage pump used in the desulfurization washing tower is usually composed of a drainage pump body, a suction pipe fixedly connected to the water inlet end of the drainage pump body, and a connecting pipe fixedly connected to the water outlet end of the drainage pump body. That is, the drainage pump body is installed on the desulfurization washing tower, and the suction pipe is inserted into the tower body of the desulfurization washing tower. The drainage pump body can be started to absorb water and discharge it through the connecting pipe.

[0004] The suction pipe is usually fixedly inserted into the body of the desulfurization washing tower and has a fixed inner diameter. The inner diameter of the washing tower is large and the water suction range is fixed. This will cause a lot of residue to remain when the drainage pump extracts the liquid in the washing tower. If too much residue remains inside the washing tower, it will affect the subsequent desulfurization. Therefore, a desulfurization washing tower drainage pump is proposed to address the above problems. Utility Model Content
