As shown in fig. 1-3The invention provides a closed air filtering type efficient ultraviolet disinfection and sterilization device, which comprises a shell 1, an ultraviolet germicidal lamp 2, a wind barrier turbulence component 3 and a coanda effect diversion generation component 4, wherein the shell 1 comprises a cavity forming a closed space, an air supply outlet 5 and an air outlet 6 communicated with the cavity, the ultraviolet germicidal lamp 2 is fixed at the bottom of the cavity, the wind barrier turbulence component 3 comprises a plurality of T-shaped wind barrier plates, and the heights of the T-shaped wind barrier plates are increased in a stepped manner along the air inlet-air outlet direction; the height of the T-shaped wind baffle is according to the formula x2＝2py，p<And (4) calculating 0. The coanda effect flow guide generation assembly 4 is fixed at one end close to the air outlet 6; the dominant wavelengths of the ultraviolet germicidal lamp 2 are 253.7nm for destroying microorganism DNA structures and 184.9nm for generating ozone; the air generates cyclone in the cavity through the air barrier turbulence component 3 and the coanda effect flow guide generation component 4, and the cyclone generates cyclone through UVC/O3And the sterilized gas is output from the gas outlet 6.
The invention relates to an ultraviolet ray disinfection and sterilization device which can efficiently kill or reduce various microorganisms in indoor air, including various bacteria and spores thereof, viruses, fungi and spores thereof, rickettsia, mycoplasma and the like. After the process of preheating the lamp tube for 3-5 min, when the device works, the UVC ultraviolet germicidal lamp 2 emits lethal chemical rays (lambda is 253.7nm) which radiate out ultra-high dose sterilization and disinfection wave bands (UVC, lambda is 200 nm-280 nm), and ozone O is generated at the same time3(λ＝184.9nm)。
The T-structure stepped progressive air barrier and the coanda effect (coanda effect) enable airflow at an air supply outlet of the air-conditioning equipment to generate primary cyclone (turbulent flow) → secondary cyclone (turbulent flow), so that the airflow of the air-conditioning equipment has enough buffering time, microorganisms and bacteria can receive lethal radiation of 4.63s Ultraviolet (UVC) and ozone (O) in a closed small-volume space3) The biochemical oxidation reaction of (1).
The flow velocity is the flow velocity of the fluid, when the flow velocity is very small, the fluid flows in layers and is not mixed with each other, and the laminar flow (laminar flow) is called; when the flow velocity is gradually increased or the air flow is affected by a wind barrier in the vertical direction, the flow lines of the fluid are no longer clearly identifiable, and a plurality of small eddies, called turbulence (turbulent flow, turbulent flow or turbulent flow), are formed in the flow field. This change is quantified by the Reynolds number (Reynolds number): where, v, ρ, μ: flow rate, density and viscosity coefficient of the fluid, d: a characteristic length. E.g., fluid flowing through a circular pipe, then d is the equivalent diameter of the pipe. The reynolds number can be used to distinguish whether the flow of the fluid is laminar or turbulent and can also be used to determine the resistance to flow of the object in the fluid. The main principle of the windbreak spoiler assembly 3 is as follows: after the wind barrier is arranged in the direction perpendicular to the incoming wind, the wind is blocked, the flowing speed of the air is reduced, small changes of the flow speed are easy to develop and strengthen, and a turbulent and irregular turbulent flow field is formed.
The air conditioner is delivered with a certain pressure P0And a propagation velocity v0Is directed perpendicular to the wind barrier. If no wind barrier exists, the airflow can directly reach the ground, and after reflection, cyclone is formed at the air return opening, so that the purposes of cold/heat and heat/cold exchange with indoor air are achieved; after the wind barrier is arranged, the edge of the wind barrier causes the transmission path of the airflow to deform and twist, the pressure of the airflow is reduced, and P is1＜P0Thereby reducing the propagation velocity of the gas flow, v1＜υ0. Moreover, due to the reflection action of the windbreak supports, a plurality of cyclones are formed on the ground between the windbreak and the ground, so that the airflow is disturbed.
At the tail end of the wind barrier of the device, the coanda effect is used for forcing the airflow to leave the original flow direction again, and the airflow tends to flow along the surface of the protrusion at the tail end of the wind barrier; when surface friction exists between the air flow of the air supply outlet of the air conditioning equipment and the tail end surface of the wind barrier of the device through which the air flow flows, the air flow of the air supply outlet of the air conditioning equipment can flow along the tail end surface of the wind barrier as long as the curvature is not large; according to Newton's third law, a body exerts a force on a fluid that deflects, and the fluid must also exert a force on the body that deflects in the opposite direction. Because of the coanda effect of the device, the air flow at the outlet of the device belongs to directional air flow, so the distance can be far transferred, and the purified air flow floats on the upper space and gradually moves downwards. The airflow directly reaches the ground and forms a cyclone at the air return opening after being reflected. The device can be prevented from repeatedly disinfecting the indoor air in a labor mode.
The air supply opening 5 comprises a plurality of parallel inclined air inlet holes, air enters one end far away from the air outlet 6 through the air inlet holes, the air outlet 6 comprises a plurality of parallel inclined air outlet holes, and the air flows to the outside from the air outlet holes from top to bottom. Specifically, the air supply outlet 5 is in butt joint with an air outlet of an air conditioner shutter, and the air outlet 6 is an air outlet of a sterilizer shutter.
The invention also comprises a quartz water pipe which can transmit ultraviolet rays, the quartz water pipe is fixed in the cavity, and the water inlet and the water outlet both penetrate through the shell 1. As long as a quartz water pipe which can transmit ultraviolet light is added in the device, the sterilization and disinfection of the circulating water can be completed while the air is purified and disinfected.
The device is a wall-mounted/ceiling-mounted or mobile structure. Relative to the wind source, the wall-mounted or ceiling-mounted air conditioner utilizes the wind sent by the air supply outlet of the air conditioner, and the object carries out closed air filtration type instant purification and disinfection on the air conditioner wind; the indoor air is formed into airflow in a movable mode, and the object performs airflow circulating type purification and disinfection on the indoor air. The shell 1 is fixed on a ceiling or a wall through a hinge 7 in a wall hanging type/ceiling hanging type, and sealing rubber 8 is arranged at the joint of the shell 1 and the ceiling or the wall. The mobile device needs a 20-30W electric power direct current vortex fan with 12-24 VDC, the installation direction of the structure is changed by changing the direction of an air outlet, and the principle structure is consistent with that of a wall-mounted type or a ceiling type.
The ultraviolet germicidal lamp 2 comprises a ballast 201 and a lamp holder 202 which are in a discrete structure, the ballast 201 supplies power to the lamp holder 202, and the ballast 201 and the lamp holder 202 are detachably fixed inside the shell 1, so that the lamp can be replaced conveniently and the lamp can be wiped regularly.
A closed air filtration type high-efficiency ultraviolet disinfection and sterilization method comprises the following steps:
step 1, processing a shell, wherein an air supply outlet and an air outlet are arranged on two adjacent side surfaces of the shell, and sealing components are fixed on the side edges of the air supply outlet and the air outlet; the housing (of a light aluminum alloy,

If the distance between the two electrodes of the air purifier is too close, electric sparks can be excited, and dust cannot be charged. Therefore, an appropriate distance is required between the electrodes, and the two electrodes do not generate sparks even when they are close to each other.
