As an important cleaning equipment of the clean room, the exhaust system has been playing a core role.So, do you know all of the following 8 exhaust systems?

1. General exhaust system: general waste gas discharged from production auxiliary rooms and living rooms is generally not required to be treated and directly discharged into the atmosphere.

2. Organic gas exhaust system: when all kinds of organic materials are used as raw and auxiliary materials in production, organic gases will be distributed in relevant places or equipment. Air exhaust devices should be installed in such places or equipment.The organic gas in the exhaust system should be treated accordingly and then discharged into the atmosphere.

3. Acid gas exhaust system: acid gas is discharged during production. In this type of exhaust system, wet scrubbing and gas absorption tower is usually set up, and the processed gas enters the atmosphere at the back.

4. Alkaline gas exhaust system: acid gas is discharged during production. In this kind of exhaust system, a wet scrubbing and gas absorption tower is usually set, which is processed and put into the atmosphere at the back.

5. Hot gas exhaust system: hot gas is discharged from various furnaces and high-temperature sterilization equipment in the production process. Due to high exhaust temperature, it can sometimes be treated by means of heat recovery.

6. Exhaust air system containing dust: the nature and concentration of dust in exhaust are different in different production processes.When the concentration of some dust is high, dust removal equipment should be used to filter the exhaust air to meet the requirements of back entry into the atmosphere.

7. Special gas exhaust system: for the generation of special gases (which are inflammable, explosive, poisonous, even highly poisonous or corrosive gases), chemical reactions shall be prevented in the exhaust system. The exhaust system shall be divided, and the special waste gas treatment device shall be selected to enter the atmosphere after reaching the emission standard.

8. Harmful and toxic exhaust system in the production of drugs: in the air outlet of some special drugs (such as strong sensitization drugs, certain steroid drugs and high activity and toxic drugs), high efficiency filters should be installed to reduce the pollution back to the atmosphere
