Abstract
The utility model relates to a fume-filtering layer for filtering and purifying cooking fume in kitchens, being a thin ventilating and adsorbing layer made of natural fiber, synthetic fiber, etc. The fume-filtering layer can firstly filter and purify fume before the fume enters a fume exhausting device so as to avoid the inner part of the fume exhausting device and the outdoor atmosphere being polluted by the fume, having good ventilation and adsorption, low price, convenient replacement and convenient use.
Description
The present invention relates to a kind of filtration, purification layer material, the filtration, purification layer material of cooking fume in particularly a kind of kitchen.
Existing oily fume exhauster all can only aspirate and discharge oil-containing flue gas body, and this oil-containing flue gas body is not purified, therefore, the inside of oily fume exhauster can get off to form grease contaminated because of the volatilization composition condensation in institute's mist extractor gas, and the oil-containing flue gas body that the filtered of being discharged purifies also causes serious pollution to surrounding environment.
The filtration, purification thin layer that the purpose of this invention is to provide cooking fume in a kind of kitchen.
The present invention is achieved in that and adopts good permeability and the strong thin layer of adsorptivity, be installed on the inlet and outlet mouth of oily fume exhausters such as cooking fume sucking filter, the cooking fume that enters and discharge is carried out filtration, purification, thereby alleviate the pollution of cooking fume greatly oily fume exhausters such as cooking fume sucking filter and outside atmosphere.
Oil smoke suction strainer layer of the present invention is the porous absorption thin layer made from materials such as natural fiber and synthetic fibers, as thin porous layers such as porous filter paper, silk flosssilk wadding paper, adhesive-bonded fabric, gauze, silk screen, mineral fibres layers, also can make composite filter above-mentioned gas permeability absorption thin layer and composite filter are made big slightly sheet by the shape of oily fume exhauster inlet and outlet mouths such as cooking fume sucking filter with two or more gas permeability absorption thin layer, fix and cover in the inlet and outlet mouth with holder, with the filtration, purification cooking fume.This filtering oil smoke layer, gas permeability and excellent adsorption, cheap can be changed after pollution at any time.
The present invention will be further described referring now to accompanying drawing.
Accompanying drawing is one of embodiments of the invention, and the filtering oil smoke layer is formed by two kinds of different thin layer composite.Thin layer 3 is a gauze layer, and thin layer 2 is a non-woven cloth layer, and the existing air permeability and good adsorptivity of gauze layer has better heat-resisting again, can protect non-woven cloth layer thereafter, prevents to damage because of spattering the high temperature oil droplet.The gas permeability of filtering oil smoke layer and adsorptivity can be controlled by the thickness and the density of non-woven cloth layer, to adapt to different operating positions.This filtering oil smoke layer is made the disk than the big 20-30mm of cooking fume sucking filter air inlet 1 diameter, and is fixed on the air inlet of cooking fume sucking filter with cover circle 4, in order to filter oil-containing flue gas body.
Filtering oil smoke layer of the present invention, make simple, the gas permeability adsorptivity is good, cheap, easy to use, can significantly reduce the pollution of cooking fume to oily fume exhauster such as cooking fume sucking filter and outside atmosphere, to improving, purify living environment significant effect is arranged.
Claims (4)
1. one kind is installed on the oily fume exhauster such as cooking fume sucking filter, is used for the filtering oil smoke layer of filtration, purification kitchen cooking fume, it is characterized in that said filtering oil smoke layer is the gas permeability absorption thin layer of being made by materials such as natural fiber and synthetic fibers.
2. according to the described filtering oil smoke layer of claim 1, it is characterized in that said gas permeability absorption thin layer can be thin layers such as porous filter paper, silk flosssilk wadding paper, adhesive-bonded fabric, gauze, silk screen, mineral fibres layer.
