103 new air-return mixing section 129 is to treat repeatedly to utilize.So design is to employ horizontal single-headed air current composition pattern, horizontal
Air is blown out from high efficiency particulate air filter one direction, and by the air return system return air of opposite side wall, the discharge of dust box haul is outdoor.Construction letter
It is single, stabilization is become after operating in the short time.
Specifically, Fig. 3, the second wall 123 are provided with return air interlayer 125, return air interlayer 125 and backwind tube
119 connections.Return air interlayer 125 can enter row buffering and storage to the air of return air.
As preferable scheme, referring to Fig. 4, high efficiency particulate air filter is arranged at the top plate 111 of factory building body 101, factory building sheet
The side wall 107 of body 101 is provided with the return air inlet 117 connected with backwind tube 119.So design is to employ non-one-way gas flow tissue
Pattern, air-flow nonlinear type move and are in irregular sinuous flow or turbulent state.Suitable for 6~9 grades of proper clean room grade, air-flow with
Nonuniform speed is not parallel to be flowed, with backflow or vortex.Turbulent flow clean room is to be taken a breath by multiple to realize clean and clean level
Not.Rate of ventilation determines the purification rank in definition (rate of ventilation is more, and purification rank is higher).Simple structure, system building
Cost, clean room 100, which expands, to be easier, in some specific use places, can and with dust-free workstation, raising clean room
The grade of 100 purification and filtering.
As preferable scheme, referring to Fig. 5, high efficiency particulate air filter is arranged at the side wall 107 of factory building body 101, factory building sheet
The floor 109 of body 101 is provided with the return air inlet 117 connected with backwind tube 119.So design is equally to employ non-one-way gas flow
Enterprise schema, air-flow nonlinear type move and are in irregular sinuous flow or turbulent state.Suitable for 6~9 grades of proper clean room grade, gas
Stream flows, with backflow or vortex so that nonuniform speed is not parallel.Turbulent flow clean room be by repeatedly ventilation come realize it is clean with it is clean
Net rank.Rate of ventilation determines the purification rank in definition (rate of ventilation is more, and purification rank is higher).Simple structure, system
Construction cost, clean room 100, which expands, to be easier, in some specific use places, can and with dust-free workstation, improve cleaning
The grade of the purification and filtering of factory building 100.
As preferable scheme, refering to Fig. 6, the side wall 107 and top plate 111 of factory building body 101 are provided with efficiently mistake
Filter, the floor 109 of factory building body 101 are provided with the return air inlet 117 connected with backwind tube 119.So design is equally to use
Liao Fei one-way gas flows enterprise schema, air-flow nonlinear type move and are in irregular sinuous flow or turbulent state.Suitable for toilet
Class 6~9 grade, air-flow flow, with backflow or vortex so that nonuniform speed is not parallel.Turbulent flow clean room is come by repeatedly ventilation
Realize clean and clean rank.Rate of ventilation determines the purification rank in definition (rate of ventilation is more, and purification rank is higher).Structure
Make simple, system building cost, clean room 100, which expands, to be easier, in some specific use places, can and with dustless work
Platform, improve the grade of the purification and filtering of clean room 100.
In the present embodiment, referring to Fig. 1 and Fig. 3 can also set wind to drench to Fig. 6, clean room 100 according to demand
Room 127, Airshower chamber 127 are arranged at the porch of clean room 100.Airshower chamber 127 is led to necessary into factory building body 101
Road, it is possible to reduce pollution problem caused by disengaging factory building body 101.Airshower chamber 127 is that a kind of stronger part of versatility is net
Change equipment, be installed between clean room 100 and non-toilet.Need to be through Airshower chamber 127 when people and goods will enter clean area
Blow leaching, its pure air blown out can remove the dust entrained by people and goods, can be effectively blocked or reduce dirt source enter it is clean
Net area.Front and rear two sect of the goods of Airshower chamber 127/ leaching room is electronic interlocking, can play a part of air-lock again, prevent non-purified sky
Gas enters clean area.Because Airshower chamber 127 is known to the skilled person technology, therefore embodiment of the present utility model is not
Do excessive introduction.
Certainly, in other embodiment of the present utility model, combined type enterprise schema can also be used, the utility model is not
Limit.Combined type is to carry out compound by turbulent flow and laminar-flow type or be used in combination, it is possible to provide local ultra-clean air.Such as it can select
It is selected as：
(1) clean tunnel：Process zone or the covering of working region 100% are made by cleanliness factor etc. with HEPA or ulpa filter
Level is improved to more than 4 grades, can save installation running expense.
This pattern need to be isolated the workspace of operating personnel with product and machine maintenance, shadow during avoiding machine maintenance
Work and quality are rung, ULSI processing procedures mostly use such a pattern.
Clean tunnel separately has binomial advantage：A. elasticity expands easy；B. can be easily carried out during maintenance of equipment in maintenance area.
(2) cleaning piping：By goods batch pass through automatic assembly line surround and purified treatment, by cleaniliness classs carry to
More than 100 grades.Because product and operator and hair dirt environment are mutually isolated, a small amount of air-supply can obtain good cleanliness factor, can save
The energy is saved, is used using being not required to artificial automatic production line as optimum.Medicine, food industry and semiconductor industry are applicable.
(3) and local toilet is filled：By the cleaning in the product processing procedure area in the turbulent flow clean room of 7~8 grades of proper clean room grade
Degree grade rises to more than 4~6 grades, thinks that production is used；Clean bench, clean working shed, clean air cabinet belong to such.
Clean bench：Grade Class3~5 grade.
Clean working shed：To surround a small space in the clean room space of turbulent flow with the transparent plastic cloth of antistatic,
Using independent HEPA or ULPA and air-conditioning unit, turn into higher clean room, its grade is 4~6 grades, is highly existed
2.5 meters or so, area coverage about below 10m2, four pillars simultaneously install castor additional, can be that elasticity is used.
The present embodiment additionally provides a kind of cleaning system (not shown), including this clean room 100.
The clean room 100 of embodiment offer of the present utility model and the operation principle of cleaning system are：
After air carries out primarily efficient filter and medium air filtration by clean air conditioner 103, by blast pipe 113 and clean room
The air outlet of high efficiency particulate air filter in 100 enters clean room 100.By clean air conditioner 103 filtering after air again by
High efficiency particulate air filter carries out secondary filter so that the pollutant such as particulate, noxious air, bacterium in air is effectively excluded.
After the air outlet 115 of high efficiency particulate air filter connects with the inside of factory building body 101, the air after sufficiently cleaned up is passed into cleaning
Factory building 100 so that the air purity in clean room 100 is improved.Meanwhile the side wall 107 of factory building body 101 or floor
109 are provided with return air inlet 117, and return air inlet 117 reclaims to the air being cleaned being passed through, and using the different paths of arrangement
Way of recycling carries out return air to air so that pure air completely covers this clean room 100, and clean room 100 is interior originally
Existing air is sufficiently discharged, and is ensured that the cleanliness factor of the every nook and cranny of clean room 100 is up to standard, is improved the effect of purification
Rate and speed.Also, return air inlet 117 is connected by backwind tube 119 with clean air conditioner 103 so that air can recycle, and save
Air resource, and the air after purification purifies again can make full use of purification resource, improves purification efficiency.
