2, the sewage dish is set in the filter-press storehouse, after sewage is filtered, delivers to again Recycling in water tank, in the time of water saving, reduced the frequency that adds water.
The accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, window formula air filtration exhaust fan, mainly be comprised of shell 1 and main frame, is arranged in installing hole reserved on wall and uses, and shell 1 is positioned at the outer one side of wall and is provided with protective cover, and protective cover is provided with air-inlet grille; The one side perforate that shell 1 faces toward within the walls, main frame passes in and out shell from perforate.Shell is fixed in installing hole, and protective cover, facing to outside wall, during host work, just can, from the air-inlet grille air amount, blow into indoor after filtration, humidification and cooling again.
In the time of need to be safeguarded main frame, only need to just main frame can be pulled out in shell from indoor, safeguard completely to push back in shell again.When window formula air filtration exhaust fan being arranged on skyscraper while using, carry out maintenance difficulties large from wall, and also dangerous, so main frame and shell adopt the mode of socket, just can be safeguarded main frame from indoor, have reduced maintenance cost and danger.
Main frame mainly comprises cabinet and is placed in dry type filter screen 2, water tank 3, air blast 4 and the controller in cabinet; Cabinet is towards an end opening of dry type filter screen, and dry type filter screen 2 seals opening, under the suction of air at air blast, from air-inlet grille, enters, and at first through the dry type filter screen, is filtered, and dust-filtering large in air is fallen.
The air inlet end of described air blast 4 is provided with kuppe 41, and the edge of kuppe is connected with the interior bore edges of cabinet, forms the filter-press storehouse of a sealing between dry type filter screen and air blast, and the air of process dry type strainer filtering enters the filter-press storehouse.
The diapire in filter-press storehouse is provided with sewage dish 5, be provided with successively wet type filter screen 6 parallel with the dry type filter screen more than on the sewage dish, leave between these wet type filter screens in ，Zai space, space and be provided with high-pressure spraying pipe 7, be provided with intensive micro-shape spray orifice on high-pressure spraying pipe 7.Water tank 3 is placed in the space between air blast kuppe and main frame front, is provided with high-pressure hydraulic pump in water tank, and high-pressure hydraulic pump is connected with flow pipe, and flow pipe enters the filter-press storehouse and is connected with high-pressure spraying pipe 7 through the kuppe 41 of air blast.
Before use, add water in water tank, during work, the air intake filter pressurization storehouse that air blast is outer by wall, high-pressure hydraulic pump is delivered to each high-pressure spraying pipe by the water in water tank through flow pipe, and the miniature spray orifice ejection of water from the high-pressure spraying pipe, form fine and closely woven water smoke.
Miniature spray orifice spreads all over the wall of high-pressure spraying pipe, forms the spray angle of 360 degree.The water mist sprinkling sprayed, to the wet type filter screen that is positioned at high-pressure spraying pipe both sides, makes its maintenance moistening.Water smoke can be combined with airborne dust and be formed larger dust granules, because particle is large, more easily by the wet type filter screen, is intercepted.
The water smoke gathered in the wet type screen surface and dust granules, the water smoke of being come by follow-up spray further supplements, and particle is increasing, finally under the effect of gravity, drips and pours in the sewage dish downwards.After also having part water smoke to cling dust, directly fall downwards in the sewage dish.
Enter the air in filter-press storehouse, while passing the space in wet type filter screen and filter-press storehouse, dust wherein and PM2.5 major part are filtered out and splash into the sewage dish or be bonded on the wet type filter screen by wet type filter screen and water smoke, through become more clean, moistening and temperature of filtered air, reduce, sucked after pressurization and to blow out main frame from air outlet 42 and enter indoorly by air blast again, to room, provide fresh air endlessly.
Described all wet type filter screens 6, bottom all is positioned at sewage dish 5, and top and another two sides prop up the main frame inwall, make to enter the air in main frame, must, through the filtration of every one deck wet type filter screen, just can enter kuppe 41.
The sizing grid difference of every one deck wet type filter screen, direction from the air intake to the air-out, grid is more and more less, and every one deck wet type filter screen not only can filter out all dust that size is larger than its grid, under the help of water smoke, can also filter out the dust less than its grid.
Every one deck wet type filter screen, be unfit to do blocked uply, in order to avoid reduce air inflow.
The air outlet 42 of air blast communicates with the air outlet of main frame, the high-pressure spraying pipe is in ejection water smoke, also can produce a large amount of anions, these anions are indoor along with the Air blowing main frame through filtration, humidification, cooling enters, and make indoor air keep fresh.
For making the sewage can Recycling, be provided with latticed demarcation strip in sewage dish 5, the sewage dish is divided into to upper water pond and lower water pond, lay sewage filtering net 51 on upper water pond diapire, the water droplet filtered through sewage filtering net advances in lower water pond.Be provided with tube connector 52 between lower water pond and water tank, be provided with check valve and booster water pump on tube connector.Water through filtering in lower water pond in tube connector 52 adds to water tank, then is delivered to the Recycling of high-pressure spraying pipe under the effect of booster water pump after pressurized.Not only can economize on water like this, can also reduce to the frequency of moisturizing in water tank.
The water pond outer wall is provided with blowoff valve on described.When main frame is safeguarded, main frame is pulled out in shell, take out dry type filter screen, wet type filter screen and sewage filtering net and cleaned, open blowoff valve, the sewage in upper water pond is drained.
Be provided with water level switch in lower water pond.Instantly the water level in water pond lower than under predefined water level in limited time, controller just can not opened booster water pump on tube connector to moisturizing in water tank.Only have and surpass the water level lower limit when water level, controller just can be opened booster water pump to moisturizing in water tank.Accordingly, also be provided with water level switch in water tank, the water level in water tank lower than under cistern water level in limited time, controller sends the warning that need to add water, and allows the high-pressure hydraulic pump in air blast and water tank quit work.
Want to allow cooling-down effect more obvious, realize by add ice cube or ice hockey in water tank.
Above-described embodiment is only for interpretation purposes of the present utility model; and be not to restriction of the present utility model, those skilled in the art, in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
