8 kinds of exhaust purification system of clean room engineering

This article gives detailed introduction to the classification of exhaust air system in clean room. As an important purification equipment for clean rooms, exhaust system has been playing a central role. So, what do you know about the following 8 exhaust systems?
1, general exhaust system: the production of auxiliary rooms, living rooms and other general exhaust emissions, generally do not need to deal with, directly into the atmosphere.
2, the organic gas exhaust system: the use of various organic substances as raw materials in the production, will emit gas organic matter in relevant premises or equipment, for this type of site or equipment shall be arranged exhaust device. The organic gas in the exhaust system should be treated accordingly and discharged into the atmosphere.
3, acid gas exhaust system: in the production of acid gas discharge, in this type of exhaust system is usually equipped with wet scrubber absorption tower, after treatment into the atmosphere.
4. Alkaline gas exhaust system: when the product is in production, there is acid gas discharged. In this type of exhaust system, a wet scrubber is usually installed and discharged into the atmosphere after treatment.
5, the hot gas exhaust system: the discharge of various stoves, in the production process of high temperature sterilization equipment with heat, due to high exhaust temperature, sometimes with heat recovery manner, if a small amount of exhaust or inconvenience when processing in taking the necessary measures after application of heat directly into the atmosphere.
6, dust exhaust system: different production process, the exhaust dust properties and concentrations are different. For some dust concentration is very high, then use dust removal equipment for exhaust filtration, meet the requirements into the atmosphere.
7, special gas exhaust system for special gas (flammable or toxic or belong to toxic or corrosive gases) to prevent chemical reaction to divide the exhaust system, exhaust system, exhaust gas treatment device for selection, to meet emission standards back into the atmosphere.
8, the production of drugs, toxic harmful exhaust system: in some special drugs (such as strong allergenic drugs, some steroidal drugs and high activity, toxic drugs) outlet of the room should be installed HEPA filter, reduce pollution into the atmosphere.
