In developed countries, purification engineering is widely used in hospitals, laboratories, factories, schools, substations, and computer rooms. Some residential buildings with high environmental requirements also have applications. In China, due to the accelerated pace of modernization, purification equipment is commonly installed in operating rooms of top three hospitals. A thousand level purification operating room is essential for brain surgery. Many hospitals in China can now perform surgeries that were previously feared or impossible due to the high purification environment. In electronic factories, due to the high purification environment, tens of millions of electronic components can be integrated in a very small volume. The electronic products we commonly use, such as mobile phones, must have a good purification environment in order to be produced. Only then can we become more refined and functional. In a purified environment, our computer room will not malfunction due to dust. In the laboratory, our experiments will not be disturbed by dust. In the factory, we can produce reassuring food with a long shelf life. The widespread application of environmental purification benefits society and humanity.
Purification standards Purification engineering generally adopts the US Federal 209 standard. It is specifically divided into levels of 100000, 10000, 1000, 100, 10, and 1. The most common application is the 10000 level. In a level 100 purification environment, it can meet the most advanced experimental requirements in China, produce precision electronic components, and perform complex craniotomy surgeries. But the construction is difficult and the cost is high. Let's take a thousand level purification room as an example and discuss the construction methods and specific process design requirements. Purification pipeline requirements The purification level of the purification room is determined based on its purpose, and the temperature, humidity, and ventilation frequency of the purification room are adjusted as needed. The temperature can be adjusted by stainless steel pipes or by dedicated air conditioning in the purification room. The humidity is adjusted using specialized equipment according to specific process requirements. According to different purification requirements, we use different construction materials and techniques. A thousand level purification room must be insulated and isolated with stainless steel plates. There should be no slight deformation at the joint of the steel plate. The isolation steel plates for the thousand level purification room currently need to be purchased from places such as Beijing and Shanghai. Purification pipelines can be made of stainless steel or galvanized. The exterior of the pipeline needs to be insulated. Before pipeline construction, it is very important to clean the inside of the pipeline, and it cannot be done until all pipelines are installed. This is the key to construction. Many projects that cannot pass acceptance are related to this, and special attention should be paid. The design of pipelines is related to the size of the purification room, the air supply volume, and the purification requirements. The size and air volume of the purification air conditioner can be adjusted as needed during the specific construction process. Due to different environments, geographical locations, and construction techniques. Design according to actual requirements. For example, if there are 50 workers and 100 workers in the same 900 square meter purification plant, the ventilation duct design needs to be adjusted. When designing, comprehensive considerations should be taken into account. Adjust the design based on experience and specific environment. Purification and filtration requirements Ventilation ducts generally adopt three-stage filtration, namely ordinary filtration device, medium efficiency filtration device, and high-efficiency filtration device. The quality of the filter needs to be carefully monitored. Poor quality filters have a short usage time and poor filtering effect. Especially due to excessive wind resistance, the air output is low. According to my investigation, the high-efficiency filter for the thousand level purification room needs to be purchased from Shanghai. The reconnection part of the ventilation duct should use high-quality sealing rings. Using sealant to compensate for the quality issue of the sealing ring can cause problems with the pipeline seal over time, which can be very troublesome to solve. It will cause unexpected losses. If there is a problem with the quality of the air supply pipeline, it is equivalent to starting over the entire project. The quality of the purification project is problematic, mostly due to pipeline installation issues. Re applying sealant can only temporarily solve the problem. Some units often replace high-efficiency filters frequently, usually due to problems with the air supply pipeline, so the installation of purification pipelines must be done carefully. The engineering supervisor cannot leave for a minute. Selection of purification fans The number of fans installed in the purification room is determined based on the usage time. If used 24 hours a day, at least two or more fans should be installed. If used for eight hours a day, install no more than two fans. If used intermittently, install a fan.
