Biohazard Safety Equipment is the safety for operating personnel and its surrounding people, what is occurred when handling dangerous microbes Pollution aerosol is isolated in the defence installation in operating area.It isolates pollution air effect, is mainly circulated by air filtration System is completed, and the air-flow that the charge air flow, sedimentation air-flow and workspace in cabinet constantly purify is promoted by blower fan, the gas of formation Curtain can be avoided by microorganism infection with Protection room operator, while sample/product can also be protected to avoid by Interior Space Entrained Institute of Micro-biology pollution in gas.But the isolation air curtain of the Biohazard Safety Equipment 70% used at present comes from circulated air, 30% is discharged, and the filtering of circulated air is completed by high efficiency particle air-flow HEPA filters, and filter uses a period of time Afterwards because grit deposits blocking action, its resistance increases therewith, the flow velocity of clean gas flow is not reached requirement, so that the peace of complete machine Full isolation performance weakens, and such laboratory operation person is by sample/product in microorganism infection, and cabinet by entrained in air The probability of microorganism pollution will increase.Therefore, develop it is a kind of isolated using fresh air, avoid in cabinet contaminated air because following The security isolation impaired performance of ring wind and make operator or sample/product by the Biohazard Safety Equipment of cross-infection are desirability 's.
Utility model content
The purpose of this utility model be to provide it is a kind of isolated using fresh air, avoid in cabinet contaminated air because of circulated air Security isolation impaired performance and make the Biohazard Safety Equipment of operator or sample by cross-infection.
The purpose of this utility model is achieved in that including chassis and cabinet, wherein:Fresh air channel is provided with cabinet And return air channel, fresh air channel connection air blower, return air channel connection air-introduced machine, fresh air channel lower section is operating room, and return air leads to Road includes the horizontal duct below operating room and the vertical air plenums on rear side of operating room;Operating room front end is provided with glass door, rear end It is separated by with vertical air plenums, bottom is turned on by Turbogrid plates with horizontal duct, and horizontal duct connects air-introduced machine, air blast through vertical air plenums Machine entrance is provided with filter, and ultraviolet germicidal lamp is provided with fresh air channel;High efficiency particulate air is provided with vertical air plenums And ultraviolet germicidal lamp, horizontal duct bottom are additionally provided with discard solution discharge port.
Further, air blower is adapted with the air quantity and blast of air-introduced machine, guarantee induction air flow ratio be 0.52m/s ± 0.025, down current flow velocity is 0.30m/s ± 0.025.
Further, ultraviolet germicidal lamp radiation intensity >=30uw/cm2
Further, pressure difference monitoring meter is provided with cabinet.
Further, air monitoring meter is additionally provided with cabinet.
The beneficial effects of the utility model are:Isolation air curtain in Biohazard Safety Equipment uses fresh air completely, avoids use from following Ring wind, when preventing that filter from using to the security isolation impaired performance of later stage complete machine, in cabinet contaminated air make operator and Sample/product is by cross-infection;The present apparatus, as isolation air curtain, can effectively reduce operation using the VMC after purification The probability that person or sample/product are infected or polluted.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
In figure:1- chassis, 2- horizontal ducts, 3- cabinets, 4- vertical air plenums, 5- high efficiency particulate airs, 6- ultraviolet germicidal lamps, 7- air-introduced machines, 8- filters, 9- air blowers, 10- fresh air channels, 11- operating rooms, 12- glass doors, 13- Turbogrid plates, 14- waste liquids Floss hole.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model is not subject in any way Limitation, any changes and modifications made based on the utility model training centre, belongs to the scope of protection of the utility model.
As shown in figure 1, the utility model includes chassis 1 and cabinet 3, wherein:Fresh air channel 10 is provided with cabinet 3 and is returned Wind passage, fresh air channel 10 connect air blower 9, and return air channel connection air-introduced machine 7, the lower section of fresh air channel 10 is operating room 11, is returned Wind passage includes the horizontal duct 2 of the lower section of operating room 11 and the vertical air plenums 4 of the rear side of operating room 11;The front end of operating room 11 is provided with Glass door 12, rear end are separated by with vertical air plenums 4, and bottom is turned on by Turbogrid plates 13 and horizontal duct 2, and horizontal duct 2 is through vertical Air channel 4 connects air-introduced machine 7, and the entrance of air blower 9 is provided with filter 8, ultraviolet germicidal lamp 6 is provided with fresh air channel 10; High efficiency particulate air 5 and ultraviolet germicidal lamp 6 are provided with vertical air plenums 4, the bottom of horizontal duct 2 is additionally provided with discard solution discharge port 14。
