Improved structure of alkaline washing tower equipment and alkaline washing process thereof

The invention discloses an improved structure of alkaline washing tower equipment, which comprises an alkaline washing tower, the upper end of the alkaline washing tower is provided with an upper cover; the invention also discloses an alkaline washing process of the alkaline washing tower equipment, which comprises the following steps: S1, the vinyl chloride gas with the alkaline liquor enters the alkaline washing tower through the gas inlet pipe, and the water pump is started. The invention aims to add a layer of pure water spraying device and a wire mesh demister on the basis of the original alkaline washing tower, and the chloroethylene gas subjected to alkaline washing is washed once again by the pure water spraying device and filtered once by the wire mesh demister before going out of the alkaline washing tower, so that the content of alkali liquor entrained in the chloroethylene gas subjected to alkaline washing can be greatly reduced; after most alkali liquor entrained in the vinyl chloride gas is remo
