Description
Technical field
The invention is related to laminar flow hood, and in particular to a kind of high efficiency fluid groove pond effect laminar flow hood.
Background technology
Purification is a kind of air cleaning unit for providing local clean environment with laminar flow hood, can neatly be placed in needs
Above the process island of high-cleanness, high, on sick bed or produce.Existing laminar flow hood includes case shell, blower fan, filter（Just
Imitate filter and high efficiency particulate air filter）, pressure chamber, macromolecule flow film and transparent weather screen etc..Laminar flow hood can be formed straight down
Laminar winds, with the purification air of streamlined flow（Hereinafter referred to as purified gas）The non-purification air of many dust is driven downwards under weather screen
The outlet on edge is continuously discharged, to reach the cleanliness factor for improving air in weather screen space.But, because its straight air stream is by equal
Stream film and inertia force promote to be formed, and are also easy to produce vortex by the effect of viscous force, cause the mixing of purified gas and non-purified gas, reduce
Clean-up effect, increases the manufacture difficulty of equipment.In addition, the pressure of pressure intracavitary is to ensure that in weather screen each particle on same plane
Can the premise that flows downward of constant speed, but have in gas under there is the current intelligence that, voltage equalizing can by structural member form and
The interference of wind-force change, can also increase the manufacture difficulty and cost of equipment.
The content of the invention
The invention technical problem to be solved is how to improve the clean-up effect of laminar flow hood, and makes the letter of its structure
Single, efficiency is stable, it is easy to manufacture.
In order to solve the above technical problems, the invention is adopted the technical scheme that：A kind of high efficiency fluid groove pond effect
Laminar flow hood, including case shell, downwards, the top of case shell is provided with air admission hole to the case shell opener, and at least one is set in case shell internal upper part
Filter is set below blower fan, case shell inner blower（In order to which blower fan is cleaned, roughing efficiency air filter can also be located at blower fan top）, case
Set below shell internal filter set on dividing plate, dividing plate it is multiple go out gas bar hole, below dividing plate along go out gas bar hole correspondence set it is multiple go out gas bar
Blast fence, multiple thermal elements are set going out below gas bar blast fence；Set up defences in thermal element bottom protecting wire net（Rather than flow film）,
Case shell bottom surrounding in protection network bottom sets reflective transparent weather screen.
Fluid mechanics principle and fluid motion rule have dexterously been used in the invention.Fluid is all from Gao Shi areas flow direction
Di Shi areas, in a groove pond Inner, fluid water just can be from groove pond along spilling only after tank is filled；The Gao Shi areas of current exist
On, Di Shi areas are under, and Water seeks its own level, flow to following bottom land；And the Gao Shi areas of hot-air are under, Di Shi areas upper, hot gas to
Upstream, flows to top bottom land.
To dissolve abstractness, by taking an opening up vertical shape tank pond as an example.If from tank bottom of pond position（Low gesture
Position）With small flow velocity, the horizontal water filling into pond, during water filling, has following effect（Phenomenon）Occur:
(1) the interface of water and airs, can grow steadily without the spray, naturally immediately can spread one out under gravity
Individual seamless desirable level face；All spaces below horizontal interface can all be tamped by water, and air is extruded more than interface；Boundary
More than face air is powerless to be flowed downwards into the deep for being mixed into water（Refer to " bubble state " it is mixed into, rather than " molecular state "
Dissolve in, water inherently dissolved with）.
(2) each particle can be linear motion in water levels uphill process, form preferable laminar flow.
Due to water inlet flow velocity it is low, it is low to inertia force be less than viscous force, transverse flow speed is decayed to zero, do not form vortex,
Interface air above is not entered in whirlpool.
Each effect is the sports rule or effect that fluid occurs in groove pond under given conditions above, is referred to as to call herein
" fluid slot pond effect ".These effects, it is static, isolate, it is superficial see very common, still, if system is dynamic micro-
That sees deeply goes to probe into and can just learn, they are that the fluid motion for creating value with very precious invention is regular！
The invention is that laminar flow hood hardware and weather screen software are synthesized an air groove pond（Hereinafter referred to as air drain pond）, with tank
It is open unlike pond（Weather screen it is lower along exhaust outlet）Down, upper example tank pond is opening up.This air drain pond is from top
The case shell of low gesture position（Bottom land）Purification hot-air is poured into weather screen, during pouring into, the thermal purification gas in weather screen is in buoyancy
Equally can naturally be pulled up a horse under effect and form a level " interface "（Thermal purification gas is upper, and cold non-purified gas is under）, one
The interface flowed downwards for tamping air drain pond periphery of the individual nothing " spray "；The powerless rising of non-purification cold air below interface, nothing
Power enters more than interface；Flow downwards to more than interface thermal purification makings point meeting " neat and tidy ", form linear motion rail
Mark, forms preferable laminar flow；The transverse flow speed for pouring into the thermal purification gas of weather screen decays to zero, does not form vortex, and whirlpool is not entered cold non-
Purified gas, clean-up effect is greatly promoted！
The invention is simple in construction, and efficiency is stable, through Hydrodynamics Laboratory simulation assembling it is demonstrated experimentally that this laminar flow hood is work(
The stronger purification air laminar flow hood of effect.In addition, if this laminar flow hood is with the systemic large-scale photo-thermal spoke being widely used at present
Class skin disease burn and scald therapy apparatus is penetrated to be combined as a whole machine（The dissipativeness convection current used heat of radiating element has been borrowed to carry out for purified gas
Heating）, kill two birds with one stone.
The present invention saves expense save space for hospital, is social resource-saving, must Cheng Gangxu！
The transparent of existing laminar flow hood weather screen is easy for observation, and weather screen of the invention is also reflective, is to reflect thermal element to weather screen
Radiant heat, reduction weather screen temperature rise interference（For weather screen high more than one meter, process island is all in bottom, and incidence angle very little, radiation is inhaled
Receive heat noiseless, but in order to more perfect in upper end, so adding the reflective of weather screen）.Can as radiant heat
Temperature rise interference is produced to cold non-purified gas, because air is too thin, heat absorption is few, ignores.
Brief description of the drawings
Fig. 1 represents the cross section structure schematic diagram of the invention high efficiency fluid groove pond effect laminar flow hood.
Embodiment
