Description

Technical Field

It has a very small vapor pressure, a high flash point, and a high ignition point. The reactor will produce a large amount of harmful gas during the production of silicone oil. The waste gas generated during the production of silicone oil needs to be treated.

Since the gas outlet end of the injection pipe is located at the bottom of the purification tank, the waste gas will move from low to high in the purification tank. During the movement, the waste gas is fully contacted with the solution for purifying the waste gas, so that the waste gas is better purified. After the waste gas is discharged from the purification tank, it flows along the passage formed by the plurality of partitions, and contacts with the atomized solution sprayed from the plurality of atomizing nozzles during the flow, and is purified again, thereby improving the purification treatment effect of the waste gas. However, the atomizing nozzle of the device is arranged on one side of the inner wall of the purification tower, and the spraying range is limited, and the waste gas purification treatment effect is general.
