The specific embodiment
See Fig. 1-4, it comprises casing 1, the sidepiece of casing 1 is provided with the low cleanliness factor side door 2 of at least one fan, at least one fan high-cleanness, high side door 3, the top of casing 1 is provided with plenum chamber 4, the upper surface of plenum chamber 4 is furnished with blower fan 5, the entrance of blower fan 5 is specially clean air port 6, the outlet of blower fan 5 is towards plenum chamber 4, the outlet of ozone carrier pipe 7 is communicated to the inside of plenum chamber 4, the import of ozone carrier pipe 7 is communicated with outside ozone generator 8, plenum chamber 4 internal placement have high efficiency particulate air filter 9, the arranged beneath of plenum chamber 4 has current-sharing zone 10, and 10 belows, current-sharing zone are specially air lock inner chamber 11, and the bottom of air lock inner chamber 11 is provided with discharge filter 12, discharge filter 12 is communicated with air outlet 14 by pipeline 13, and air outlet 14 is positioned at the top of casing 1.Low cleanliness factor side door 2, high-cleanness, high side door 3 have been connected respectively gate inhibition 15; Gate inhibition 15 positions of casing 1 are provided with differential pressure pickup 16, and differential pressure pickup 16 connects outside PLC system 17, but PLC system 17 connects the adjusting air valve of air outlet 14; Be provided with electric control valve 18 on the ozone carrier pipe 7; The inside of air lock inner chamber 11 is provided with ozone sensor 19, and ozone sensor 19 connects outside PLC system 17, and PLC system 17 connects electric control valve 18; Be provided with homogenizing plate 21 in the current-sharing zone 10 or/and current-sharing film 20; Discharge filter 12 is specially medium effeciency filter 22, roughing efficiency air filter 23 two-stage filters, and PLC system 17 can fasteningly be installed on the outer wall of casing 1.
Its operating principle is as follows:
For preventing pollution and the cross pollution between two independent clean zone materials, the personnel, low cleanliness factor side door 2, interconnect between the gate inhibition 15 between the high-cleanness, high side door 3 and (not shown in FIG. by gate control system, belong to existing mature technology) coordinate control, guarantee that low cleanliness factor side door 2 and high-cleanness, high side door 3 can not open simultaneously.
Transport material by low cleanliness factor side direction high-cleanness, high side: low cleanliness factor side personnel swipe the card by gate inhibition 15 and open low cleanliness factor side door 2, close after people and material enter material enter with material take off bag, outer clearly; Then swipe the card and open low cleanliness factor side door 2, close low cleanliness factor side door 2 after personnel withdraw from, low cleanliness factor side personnel open disinfectant program; Air lock self-cleaning after sterilization finishes, door must not be opened during self-cleaning, is swiped the card by high-cleanness, high side personnel after self-cleaning finishes and opens high-cleanness, high side door 3, and personnel close high-cleanness, high side door 3 after entering material being transported, and air lock is stand-by.
Transport material by the low cleanliness factor side of high-cleanness, high side direction: high-cleanness, high side personnel swipe the card and open high-cleanness, high side door 3, material is transported into air lock inner chamber 11 rear personnel to be withdrawed from air lock inner chamber 11 and closes high-cleanness, high side door 3, swiped the card by low cleanliness factor side people again and open low cleanliness factor side door 2, close low cleanliness factor side door 2 after material transported, air lock is stand-by.
Under the normal toilet of the air lock state, outdoor clean air enters from clean air port 6, behind plenum chamber 4 interior high efficiency particulate air filters 9 by even flow plate 20 Vertical Uniforms enter in the air lock inner chamber 11, and then through discharging outdoor by air outlet 14 behind the discharge filter 12.Resh air requirement and exhaust air rate are to be input to PLC system 17 by differential pressure pickup 16 digitlizations, dynamically keep room pressure but automatically regulate afterwards air outlet adjusting air valve opening angle.Facilitate so real air lock inner chamber 11 interior relative malleation or negative pressure state.Because the self-loopa air quantity of whole air lock inner chamber 11 (ventilation rate can be set according to toilet's lustration class) and blower fan 5 pressure (greater than 400Pa) are far longer than the toilet of both sides; so air lock inner chamber 11 keeps relative barotropic state with respect to the both sides clean area in the whole course of work; thereby prevent pollution and cross pollution between two independent clean zone materials, the personnel, the safety of protection personnel and surrounding environment.
Be an airtight self-circulation system during air lock sterilization state, the air of air lock when work working region is filtered by discharge filter 12 first, and air-flow enters plenum chamber 4 by blower fan is laggard; Plenum chamber 4 interior air filter through high efficiency particulate air filter 9 and enter uniform flow zone 10, and after ozone mixed, vertical current was in the working region of air lock inner chamber 11.Can be higher owing to ozone concentration in the disinfecting process; the people is known from experience formation to be threatened; therefore also the long-living pollution of surrounding environment is kept relative negative pressure state at this Process Gas lock chamber inner chamber 11 with respect to other clean area; thereby prevent pollution and cross pollution between two independent clean zone materials, the personnel, the safety of protection personnel and surrounding environment.
Air lock is in the ozonization process, concentrate generation ozone by ozone generator 8, be transported to plenum chamber 4 by ozone carrier pipe 7, with mix through the air circulation of high efficiency particulate air filter 9, then through homogenizing plate 21 or/and current-sharing film 20 is sent to the working region of air lock inner chamber 11 that air lock inner chamber 11 and materials inside are carried out disinfection.Ozone concentration can be mediated through 18 pairs of delivery of ozone concentration of electric control valve in the disinfecting process, to satisfy the demands.
After this air lock was finished in the sterilization process time, system entered the sterilization exhaust condition, and this moment, clean air port 6 and air outlet 14 were opened, indoor remaining ozone is discharged air lock inner chamber 11, greatly shorten the sterilization stand-by period, and detected with ozone concentration, improved Security of the system.
