Detailed description of the invention
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 to the inside of plenum chamber 4, the ozone generator 8 of the inlet communication outside of ozone carrier pipe 7, plenum chamber 4 internal placement has high efficiency particulate air filter 9, the arranged beneath of plenum chamber 4 has current-sharing region 10, air lock inner chamber 11 is specially below current-sharing region 10, 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, 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 position of casing 1 is provided with differential pressure pickup 16, and differential pressure pickup 16 connects outside PLC system 17, and PLC system 17 connects the adjustable air-valve of air outlet 14; Ozone carrier pipe 7 is provided with electric control valve 18; 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; Homogenizing plate 21 is provided with or/and current-sharing film 20 in current-sharing region 10; Discharge filter 12 is specially medium effeciency filter 22, roughing efficiency air filter 23 two-stage filter, and PLC system 17 fasteningly can be installed on the outer wall of casing 1.
Its operating principle is as follows:
For preventing pollution between two independent clean region materials, personnel and cross pollution, low cleanliness factor side door 2, to be interconnected between gate inhibition 15 between high-cleanness, high side door 3 and (not shown in FIG. by gate control system, belong to existing mature technology) cooperation control, guarantee that low cleanliness factor side door 2 and high-cleanness, high side door 3 can not be opened simultaneously.
Transport material by low cleanliness factor side direction high-cleanness, high side: low cleanliness factor side personnel are swiped the card by gate inhibition 15 and open low cleanliness factor side door 2, people and material enter rear closedown material enter material carried out taking off wrap, clearly outer; Then swipe the card and open low cleanliness factor side door 2, after personnel exit, close low cleanliness factor side door 2, low cleanliness factor side personnel open disinfectant program; Sterilization terminates rear air lock self-cleaning, and during self-cleaning, door must not be opened, and swiped the card by high-cleanness, high side personnel after self-cleaning terminates and open high-cleanness, high side door 3, after personnel enter and transported by material, close high-cleanness, high side door 3, air lock is stand-by.
Material is transported: high-cleanness, high side personnel swipe the card and open high-cleanness, high side door 3 by the low cleanliness factor side of high-cleanness, high side direction, after material being transported into air lock inner chamber 11, personnel exit air lock inner chamber 11 and close high-cleanness, high side door 3, swiped the card by low cleanliness factor side people again and open low cleanliness factor side door 2, material is transported the low cleanliness factor side door 2 of rear closedown, air lock is stand-by.
Under air lock normal toilet state, outdoor clean air enters from clean air port 6, entered in air lock inner chamber 11 by even flow plate 20 Vertical Uniform after high efficiency particulate air filter 9 in plenum chamber 4, and then by outside air outlet 14 discharge chamber after discharge filter 12.Resh air requirement and exhaust air rate are input to PLC system 17 by differential pressure pickup 16 digitlization, automatically regulates the adjustable air-valve opening angle of air outlet dynamically to maintain room pressure afterwards.Facilitate relative malleation or negative pressure state in real air lock inner chamber 11 like this.Because the self-loopa air quantity (ventilation rate can set according to toilet's lustration class) of whole air lock inner chamber 11 and blower fan 5 pressure (being greater than 400Pa) are far longer than the toilet of both sides; therefore air lock inner chamber 11 keeps relative barotropic state relative to both sides clean area in the whole course of work; thus prevent the pollution between two independent clean region materials, personnel and cross pollution, the safety of protection personnel and surrounding environment.
Be an airtight self-circulation system during air lock sterilization state, during air lock work, the air of working region is first filtered by discharge filter 12, air-flow by blower fan laggard enter plenum chamber 4; In plenum chamber 4, air filters through high efficiency particulate air filter 9 and enters uniform flow region 10, after mixing, flows vertically in the working region of air lock inner chamber 11 with ozone.Because ozone concentration can be higher in disinfecting process; know from experience to be formed to people and threaten; also therefore relative to other clean area, negative relative state is kept at this Process Gas lock chamber inner chamber 11 to the long-living pollution of surrounding environment; thus prevent the pollution between two independent clean region materials, personnel and cross pollution, the safety of protection personnel and surrounding environment.
Air lock is in ozonization process, concentrated by ozone generator 8 and produce ozone, plenum chamber 4 is transported to by ozone carrier pipe 7, mix with the air circulation through high efficiency particulate air filter 9, then through homogenizing plate 21 or/and the working region that current-sharing film 20 is sent to air lock inner chamber 11 carries out disinfection to air lock inner chamber 11 and materials inside.In disinfecting process, ozone concentration can be passed through electric control valve 18 pairs of delivery of ozone concentration and mediates, to satisfy the demands.
This air lock is after the sterilization process time completes, and system enters sterilization exhaust condition, and now clean air port 6 and air outlet 14 are opened, remaining for indoor ozone is discharged air lock inner chamber 11, substantially reduce the sterilization stand-by period, and detect with ozone concentration, improve the safety of system.
