What is the standard of 0.1 million purification workshop? The 0.1 million-level purification workshop standard is the number of ventilation times in clean rooms.1. the number of ventilation times in the 100,000 clean room is not less than 15 times/h.2. the number of ventilation times in the 10 th grade clean room is not less than 25 times/h.3. the number of ventilation times in the thousand clean room is not less than 50 times/h.Purification,Mainly by the clean air flow, the indoor air is constantly diluted,Gradually discharge the indoor pollution,To achieve the clean effect.1. the material of the purification workshop is to purify the factory wall and the top plate. generally, it is made of 50mm thick sandwich color steel plate,It is characterized by beautiful appearance, strong rigidity, good insulation performance and easy construction.2. epoxy self-flowing flat floor or advanced wear-resistant plastic floor can be used on the floor of the purification workshop,There are anti-static requireme
How to determine the flow rate of the multi-media filter backwashing pump? 1. the backwashing strength of anthracite is 10 L/m2 * s, quartz sand is 15 L/m2 * s, and 12L/m2 * s is taken in multiple media.2. multiply the counter-washing strength q by the filter area of the equipment to get the counter-washing flow. the counter-washing head is generally> 15mH2O. Considering the pipe resistance and pressure loss, it is recommended to choose a 25 m head pump.The strength of the reverse wash is 10L/m2 * s, which is expressed by q. The backwashing flow is equal to the backwashing strength q multiplied by the filter area of the equipment, so that the pump flow can be obtained. 1. multi-media filters use one or more filter media to pass water with high turbidity through granular or non-granular materials of a certain thickness at a certain pressure, in order to effectively remove suspended impurities and clarify the water, the commonly used filter materials include quartz sand, anthracite coal, manganese sand, etc.,
