Clean room exhaust gas treatment steps
The clean room is also called the clean room. The clean room generally includes the industrial clean room and the biological clean room. The industrial clean room, especially the electronic industry clean room, discharges the main waste components: general exhaust gas, hot exhaust gas, organic waste gas, acid and alkali waste gas, Special exhaust gas such as phosphorus, dust-containing exhaust gas, etc., different industries, different products, and the exhaust gas emitted by the different components, but must be processed to meet the national emission standards before being discharged to the outside.
1. The general exhaust gas discharged from the general living room, duty room and bathroom can be directly discharged to the outside.
2. When the organic waste gas discharged exceeds the standard, it must be treated by the organic waste gas treatment equipment to discharge the organic waste gas. The treatment methods include activated carbon adsorption method and liquid absorption method.
3. If the acid-base exhaust gas is discharged in the production process, it is discharged through the wet scrubbing absorption tower for neutralization and treatment.
4. The exhausted hot exhaust gas can be directly discharged under normal conditions. If the temperature is high, heat insulation measures must be taken to avoid injury.
5. The dusty exhaust gas must be discharged to the atmosphere after being dusted by a suitable dust removal device.
6. Special exhaust gases such as phosphorus and arsenic are first prevented from generating chemical reactions in the exhaust system and discharged through standard exhaust gas treatment equipment. The general treatment methods are dilution method, absorption method, adsorption method, catalytic combustion method and the like.
The exhaust of biological clean rooms, especially biosafety laboratories, generally contains active microorganisms such as toxic and harmful germs. Therefore, such exhaust air must be filtered and sterilized before being discharged. For example, the exhaust of the operating room must be filtered through the medium-efficiency filter before being discharged to the outside; the exhaust of the P3 laboratory must be filtered through the high-efficiency filter before being discharged to the outside; the exhaust of the P4 laboratory must be filtered by the two-stage high-efficiency filter. Can be discharged outdoors. Consider the safety of Zui, the efficient filtration of the bag into the bag
