As an important purification equipment in a clean room, the exhaust system has always played a core role in it. The following editor will give you a detailed introduction to 8 types of exhaust systems in clean rooms:  1. General exhaust system: General exhaust gas from production auxiliary rooms, living rooms, etc., generally does not need to be treated and directly discharged into the atmosphere.  

2. Organic gas exhaust system: When various organic substances are used as raw and auxiliary materials in production, organic substances will be emitted in related places or equipment. Exhaust devices should be installed for such places or equipment. The organic gas in the exhaust system must be treated accordingly before being discharged into the atmosphere.   

3. Acid gas exhaust system: acid gas is exhausted during the production of the product. In this type of exhaust system, a wet scrubbing absorption tower is usually installed, and the exhaust gas is discharged into the atmosphere after treatment.   

4. Alkaline gas exhaust system: acidic gas is exhausted during the production of the product. In this type of exhaust system, a wet scrubbing absorption tower is usually set up, and it is discharged into the atmosphere after treatment. 

5. Hot gas exhaust system: all kinds of furnaces and high-temperature sterilization equipment in the production process are exhausted with hot gas. Due to the high exhaust temperature, heat recovery and other methods can sometimes be used for treatment. If the exhaust volume is small Or when it is inconvenient to deal with, it should be discharged directly into the atmosphere after taking necessary heat insulation measures.   

6. Dust-containing exhaust system: In different production processes, the nature and concentration of dust in the exhaust are different. For some high dust concentrations, dust removal equipment should be used to filter the exhaust gas and discharge into the atmosphere after meeting the requirements. 

7. Special gas exhaust system: For the production of special gas (inflammable, explosive or toxic or even highly toxic or corrosive gas) to prevent chemical reactions in the exhaust system, it is necessary to divide the exhaust system and select special exhaust gas The treatment device is discharged into the atmosphere after reaching the emission standard. 

8. Harmful and toxic exhaust system in the production of pharmaceuticals industry: In the exhaust vents of some special drugs (such as highly allergenic drugs, certain steroid drugs and highly active and toxic drugs) rooms, high efficiency filters should be installed to reduce Discharge into the atmosphere after pollution.
