One end of the connecting pipe 24 is fixedly connected to a connecting water tank 5, and a circulation pump 6 is arranged on one side of the connecting water tank 5;
[0021] When in use, the waste gas to be treated enters the gas collecting box 1 through the tail gas branch pipe, and enters the slurry tank 2 from the lower part of the gas collecting box 1. The waste gas is deflected 180° in the gas phase space of the slurry tank 2, and the gas turns upward and enters the bottom of the cyclone spray tower 3. The liquid is captured downward in the liquid phase of the slurry tank 2. In the cyclone spray tower 3, the gas flows from bottom to top, and the alkali liquid droplets and the waste gas are countercurrently transferred. Most of the chlorosilane, trichlorosilane, and tetrachlorosilane in the waste gas are removed. Components such as silicon dioxide and hydrogen chloride are hydrolyzed and neutralized by alkali solution, releasing hydrogen chloride and hydrogen. Part of the hydrogen chloride is neutralized by alkali solution. The empty tower gas velocity of swirl spray tower 3 is controlled at 1-3m / s, and the spray density of swirl spray tower 3 is controlled at 15-25m3 / m2 / h. The residual gas enters the adjacent venturi swirl spray tower 4 from the top of swirl spray tower 3 through the air duct. In the venturi swirl spray tower 4, all chlorosilane, trichlorosilane, Silicon tetrachloride is hydrolyzed by the circulating alkali solution, and part of the hydrogen chloride is absorbed by the alkali solution. The droplets sprayed down from the swirl spray tower 3 and the Venturi swirl spray tower 4 contain chlorosilane, trichlorosilane and silicon tetrachloride that are not fully hydrolyzed, and enter the slurry tank 2 at the bottom for further hydrolysis and neutralization.

The liquid droplets are atomized and accelerated by the high-speed air flow. During the acceleration process of the liquid droplets, due to the inertial collision between the liquid droplets and the particles, the capture of fine particles is realized. The gas re-enters the slurry tank 2 from the lower part of the Venturi cyclone spray tower 4. After a 180° turning and baffle, the liquid is captured downward into the liquid phase of the slurry tank 2, and the gas turns upward and is discharged from the air outlet 46.
