Pipe is delivered in required laboratory, then by dividing return-air duct and return-air duct to feed gas into air return section, is passed through successively again
Medium effeciency filter, air-conditioner set section, dehumidifying section and primary air fan enter in laboratory, and this design need not increase aspiration pump
Realize, but the gas out of laboratory out is very clean, then the sky after air return section with coming through low efficient filter
Gas mixes, but air can not only filter clean by low efficient filter, and impurity in air is still also a lot, pollutes
The pure air that return-air duct comes out, eventually enter into the gas in laboratory and be unsatisfactory for wanting for Superclean Lab cleaning gas degree
Ask, and this section of medium effeciency filter, air-conditioner set section, dehumidifying section and primary air fan unit need to carry out work according to air intake size
Make, increase energy consumption, this design method is unfavorable for environmental protection.
Utility model content
The technical problems to be solved in the utility model, which is to provide one kind, can reduce energy consumption, and enter with the passage of usage time
Enter the Superclean Lab purifying air-feeding air return system that the cleaning gas degree in Superclean Lab is higher, meets environment protection requirement.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of Superclean Lab purifying air-feeding returns
Wind system, including be sequentially connected fresh air section, low efficient filter, medium effeciency filter, preposition high efficiency particulate air filter, air-conditioner set section,
The section that dehumidifies and primary air fan；The gas outlet of the primary air fan connects main intake stack；The main intake stack connects multiple points
Intake stack；Described point of intake stack is communicated in laboratory；Each the air outlet of intake stack is divided to be equipped with high efficiency particulate air filter,
It is provided with the laboratory and divides return air duct；Described point of return air duct connects main return air duct, and the main return air duct is efficient
The main intake stack is connected before filter, air extractor is provided with the main return air duct.
Preferably, the return air inlet inner side for dividing return air duct is provided with filter.
Preferably, the filter is middle effect or high efficiency particulate air filter.
Preferably, it is additionally provided with silencer on the main return air duct.
Preferably, the air extractor is air exhauster or aspiration pump.
Preferably, the entrance for dividing return air duct is provided with air door.
The beneficial effects of the utility model are：Because main return air duct is provided with air extractor；Air extractor passes through pipeline
Main intake stack is connected, the clean gas out of Superclean Lab out, is just directly taken out through the air extractor on main return air duct
Intake stack is become owner of, is again introduced into according to a certain percentage with the new gas mixing after purification of air in laboratory, it is generally main
Return air duct gas：Primary air fan=80-90%：10-20% ratio is matched, and is so accounted for by the gas in main backwind tube
According to major part, avoid return air and slightly imitated or the pollution again of medium effeciency filter so that indoor air iterative cycles filtering, greatly
The big energy for reducing low efficient filter, medium effeciency filter, preposition high efficiency particulate air filter, air-conditioner set section, dehumidifying section and primary air fan
Consumption, and as the time of system work operation is more long, it is purer into the gas in laboratory, reach and lower air background
It is required that meet environment protection requirement.
