Description

A kind of waste gas treatment device for pharmaceutical intermediates

technical field

The utility model relates to the technical field of waste gas treatment devices, in particular to a waste gas treatment device for pharmaceutical intermediates.

Background technique

Pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the pharmaceutical synthesis process. This chemical product does not require a production license for pharmaceuticals and can be produced in ordinary chemical plants. The production process of pharmaceutical intermediates Due to the chemical reaction involved, a certain amount of waste gas will be generated during the processing process. Therefore, a special waste gas treatment system is required to treat and purify the waste gas before it can be discharged into the atmosphere. The waste gas purification mainly refers to industrial waste gas such as dust generated in industrial places. Particulate matter, smoke and dust, odorous gases, toxic and harmful gases are treated. Common waste gas purification includes factory dust and waste gas purification, workshop dust and waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc.

At present, most of the existing waste gas treatment devices use a spray tower to purify the waste gas, and the purified water is sprayed to the waste gas. The device often blocks the air inlet due to impurities such as fluff and large particles in the air, which is relatively troublesome to clean. Therefore, the existing waste gas treatment device has the disadvantages of high waste gas purification cost and easy blockage of the air inlet.
