6, new wind strong compensation fresh air is finished by fresh wind tube road 10.The exhaust piping combustion gas.

7, be provided with first high efficiency

particulate air filter

21 and 22, two high efficiency particulate air filters of second high efficiency particulate air filter are worked jointly, first high efficiency particulate air filter 21 is from the positive air-out of main frame, and second high efficiency particulate air filter 22 is from the back side air-out of main frame.In the design of air outlet, air-out Bian gets two-way air-out, both in the positive air-out of main frame, again simultaneously in the air-out of the back side of main frame, the air quantity of positive air-out and back side air-out is identical, the identical wind of wind speed, direction are opposite, back side wind and metope bump refraction back, building and move the while to the center diffusion along metope, and positive air-out and back side air-out form one fast one 180 slow degree horizontal plane air-out because of refraction.Make in the room fast wind draw at a slow speed wind and spread wind at a slow speed simultaneously and promote quick wind again, make the eddy current that is about to form be subjected to drawing co-flow and not produce vortex wind, thereby realize being sterilized the nothing sterilization dead angle circulated air of the single flow direction in room.Fig. 4 is the Mathematical Modeling schematic diagram that novel laminar flow dynamic air of the present utility model purifies sterilizing machine air draught histokinesis rule, and it is as follows to Figure 4 shows that the novel laminar flow dynamic air of the air-out presentation graphs that is parallel to ground purifies sterilizing machine air draught histokinesis rule: purify high efficiency particulate air filter that wind purifies sterilizing machine from novel laminar flow dynamic air and flow out and enter big space and form flowing of continuous diffusion.The fluid micellar that flows produces strong random pulsation, realizes forming the Turbulence Flow air-flow with momentum-exchange and the mass exchange of surrounding medium air.This air-flow is owing to be from the outlet of high efficiency particulate air filter ejection, and air inlet also is the exchange of carrying out in the same space.The purpose of exchange is mass exchange, and the air-flow that namely enters is subjected to the obstruction of filter, and other materials that adsorbing on the particle in the air-flow and the particle are filtered simultaneously, stop, are deposited on the interface of filter.When air-flow sees through the interface and enters big space, the physical dimension standard of filter the motion of air-flow be to flow in the plane.And constant based on rotation speed of fan, the plane flowing gas is with even speed V.Flow out the plane fluid motion mode that forms from air outlet, the place forms the tangent discontinuity face in the outlet, developing into horizonally projected jet along discontinuity surface flows, when effluxvelocity not too hour, tangent discontinuity face instability, vortex appears, these vortexs are done irregular movement in flowing, produce momentum and the mass exchange of gas micelle thus, form the boundary layer of turbulent jet, because the momentum of air mass and mass exchange are constantly aspirated ambient air and are flowed forward by jet, the width of purifying gas flow constantly increases, and the purifying gas flow of ejection itself then constantly slows down, on disappearance or bumping against face wall, as shown in Figure 4, purifying gas flow is considered as in section speed uniformly.Because purifying gas flow mixes with the continuous of surrounding air, forming the zone with very big velocity gradient at the exit streamwise is the boundary layer of purifying gas flow and air.This regional inner boundary is that speed equals muzzle velocity V.The boundary line, external boundary then is that speed is close to zero boundary line, obviously purifying gas flow boundary layer streamwise is constantly expanded to both sides, external boundary is outwards expanded, drive air dielectric and enter the boundary layer, become vortex, inner boundary is expanded to the center, the zone that makes speed equal to export the initial velocity value reduces gradually, streamwise purification by diffusion flow boundary layer air is more and more wideer, to the 8-8 section, intersect in border in the boundary layer and purifying gas flow axle center, at this moment have only the fluid of purifying gas flow central spot to keep initial velocity amplitude, central speed from outlet A-A to purifying gas flow the B-B cross section equals initial velocity, regional B ' the AA that keeps velocity amplitude to equal the initial velocity value is core potential energy district, this regional length changes according to physical dimension shape and the initial purge air flow state of the design of air outlet, the length of calculating its potential energy district as the wind speed in measurement core potential energy district under the plane jet situation is 10b, the wind speed that is high efficiency particulate air filter length of side 40cm is 0.3m-0.4m/s, the length in core potential energy district is 30-40, this zone is the required field of operation clean-up effect of operating table deposit position optimum position, and the plane air-flow is the horizontal laminar flow air-flow.Particle along continuous straight runs in the air current composition move its effect of inertia can vertically not fall the motion and drop to above the wound.This horizontal laminar flow motion mode has thoroughly been replaced the vertical laminar flow mode, greatly reduces secondary pollution, and it is very clear and definite to purify purpose.

Yet prior art has only an air outlet, during moving, air mass can form the cyclone eddy current owing to momentum-exchange very soon in the external world, equally just change the direction of motion and make the barrier choke face back side form the dead angle that air-flow can't arrive because the obstacle in the air-flow running route and diffusion breadth run into collision along the air-flow of interfacial diffusion, cause momentum-exchange and mass exchange to move, more can not form the air current composition of the single flow direction and cause the sterilization not thorough.

Therefore, the utility model is in the design of air outlet, and air-out Bian gets two-way air-out, namely 180 °.Outlet on the contrary on the straight angle, air quantity is constant, wind speed is constant, and the angle of ingenious application wall reaches the purpose that relay promotes air-flow, has simplified the difficult point that how the relay field produces in the equipment design.Air outlet is simultaneously faced than large space, another side is apart from closely 40-60 centimetre when being 45 of room metope, metope has become the reflecting wall that facings the wind, air-flow is divided into along angle direction distributary phenomenon by 45 ° of angles, and air-flow is done along the body of wall interface when moving along the body of wall interface to making diffusion motion than large space, when the air mass of making diffusion motion along metope when doing horizontal movement outer boundary diffusion air-flow and cross, the horizontal movement air-flow drives and advances in the same direction along wall diffusion motion air-flow, the air-flow of making diffusion motion along wall also plays a driving role to the air-flow that moves horizontally on the other hand, the air-flow of this moment, horizontal movement speed is greater than along body of wall interface movement velocity, form speed wind, horizontal gas flow drives along body of wall interfacial diffusion air-flow, do compressional movement to the center along body of wall interfacial diffusion air-flow promotion horizontal gas flow outer boundary and can not form the cyclone eddy current, make its cyclone eddy current in soon forming, be pushed air-flow and push horizontal gas flow, make the cyclone eddy current be difficult to form, reduce and be difficult to because of eddy current in the air current composition motion in the space and form, reduce at the dead angle in the space, air current composition has formed the single flow direction, owing to be air-flow momentum-exchange and the mass exchange in the confined space, air current composition becomes the closed loop air motion in the confined space, momentum-exchange and mass exchange reached 997 at 60 minutes with interior.The exchange effect, particle and be attached to material on the particle by rapidly filtering reaches design effect.

Function of the present utility model: 1, man-machine coenecium, 2, program control control, remote control control, manually control all can, 3, uitraviolet intensity shows automatically, 4, reported to the police automatically when screen pack loses efficacy, 5, new fetch control compensation, 7, the program control eliminating of waste gas.
