Abstract
The present invention provides an oily fume filtering plate capable of separating oily fume from gas. Said oily fume filtering plate includes front plate and two curved tiles which are oppositely overlapped. On the front plate a gas inlet is set, between two curved tiles a transition gas hole and a gas outlet are set; the front plate and upper curved tile are formed into front cavity, between curved tiles a rear cavity is formed, between the gas inlet, transition gas hole and gas outlet a zigzag gas-feeding channel is formed, said front plate can be used as carrier of national and folk custom culture and art.
Description
Technical field
The present invention relates to a kind of filter, be meant the cooking fume filtering plate that the oil smoke in the gas can be separated especially.
Background technology
The cooking fume filter that uses generally all is a network structure at present, the screen pack that promptly adopts wire netting or other material to make is placed on the passage of soot gas circulation, when soot gas passes through, oil smoke in the gas contacts with screen pack, its heat is filtered net and absorbs, oil smoke promptly condenses into liquid oil droplet attached on the screen pack, reaches the purpose of separating oil smoke.But because screen pack is made up of many apertures, most of oil smoke does not contact promptly with screen pack and directly passes through, thereby oil smoke separating effect and efficient are all relatively poor; Because separated oil droplet attached on the screen pack, has promptly blocked the aperture of screen pack in the course of time, make air drag become big simultaneously, the oil smoke separating effect reduces, and also is unfavorable for further improving the separating effect of oil smoke.
Summary of the invention
In order to overcome existing cooking fume filter oil smoke inferior separating effect, the deficiency that air drag is big the invention provides a kind of good separating effect, the cooking fume filtering plate that air drag is little.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cooking fume filtering plate, it is characterized in that: it comprises that header board and two tiles are overlapping in opposite directions, resemble the cover tile mode of ancient rural area when building a house and place, header board is provided with air inlet, leaves transition gas port and gas outlet between two tiles; Header board and last tile constitute ante-chamber, constitute back cavity between the tile, form the inlet channel of turnover between air inlet, transition gas port and the gas outlet.
The invention has the beneficial effects as follows: simple in structure, cost of manufacture is not high, air drag is little, and the method for stacked many group cooking fume filtering plates improves the oil smoke separating effect before and after can adopting according to different, and the oil smoke clean absorption rate that passes through be can be applicable to the various occasions that need carry out isolation of purified to airborne oil smoke greater than 90%.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the front view of cooking fume filtering plate of the present invention.
Fig. 2 is the local amplification view of Fig. 1 along the A-A direction.
Fig. 3 is the front view of the another kind of embodiment of cooking fume filtering plate of the present invention.
The specific embodiment
As Fig. 1, shown in Figure 2, cooking fume filtering plate of the present invention comprises header board 1, goes up tile 2 and following tile 3, header board is provided with air inlet 4, is reserved with transition gas port 5 between the last tile, is reserved with gas outlet 6 between the following tile, header board and last tile constitute ante-chamber 7, constitute back cavity 8 up and down between the tile.Header board 1, upward tile 2 and the 3 employing metallic plates making of following tile are made better effects if with the alloy aluminium sheet, and header board 1 plates one deck titanium or titanium silver again.The air that contains oil smoke forms air and streams before entering air inlet 4, because the flow velocity of air and the effect of streaming, make airborne oil smoke under the effect of inertia force, thrown to header board, the heat of oil smoke is absorbed by header board, oil smoke is frozen into promptly that little oil droplet is separated and attached on the header board, finishing for the first time, oil smoke separates; Air streams air and eddy current because the variation factors such as (expansions) of volume space forms by ante-chamber 7 time, the flow velocity of air, the double action and the two air inlet air-flows that stream with eddy current collide in opposite directions, make airborne oil smoke under inertia force and action of centrifugal force, thrown on the ante-chamber wall, the heat of oil smoke is absorbed by the ante-chamber wall, oil smoke is frozen into promptly that little oil droplet is separated and attached on the ante-chamber wall, finishing for the second time, oil smoke separates; Stronger air streams transition gas port place (compression) air and stronger eddy current (turbulent flow) because the variation factors such as (expansions) of volume space forms by back cavity 8 time, because the flow velocity of air and stream double action with turbulent flow, make airborne oil smoke under inertia force and action of centrifugal force, thrown on the back cavity wall, the heat of oil smoke is absorbed by the back cavity wall, oil smoke is frozen into promptly that little oil droplet is separated and attached on the back cavity wall, finishing for the third time, oil smoke separates.
Embodiment: shown in Figure 2 as Fig. 1, cooking fume filtering plate of the present invention comprises header board 1, goes up tile 2 and following tile 3, and header board is provided with air inlet 4, is reserved with transition gas port 5 between the last tile, is reserved with gas outlet 6 between the following tile; Header board and last tile constitute ante-chamber 7, and last tile and following tile constitute back cavity 8, form the inlet channel of turnover between air inlet 4, transition gas port 5 and the gas outlet 6.Air inlet 4, transition gas port 5 and gas outlet 6 constitute near 0 ° can guarantee and strengthen the air angle of turnover suddenly, it is more abundant that air is streamed with the formation of eddy current, the probability that oil smoke contacts with cooking fume filtering plate has improved the separative efficiency of oil smoke greatly near 100%.
The air inlet 3 of above-mentioned cooking fume filtering plate is a star, and transition gas port 5 and gas outlet 6 are strip.As shown in Figure 3, the outline of the air intake surface that each air inlet 3 is formed can be the outline of Chinese character, also can be the foreign steamer of various art patterns.As Fig. 1, shown in Figure 3, the outline of header board 1 can be the outline of Chinese character, expresses cultural traits national, folk custom.
In order further to improve the separating effect of oil smoke, can be according to different use occasions or environmental requirement, employing will be organized the cooking fume filtering plate stacked use in front and back or the use that is combined into one more, make its structure compact more, thereby containing the oil smoke amount, reduces greatly the air that makes the process filter, to satisfy different use occasions or environmental requirement, as family kitchen, restaurant, restaurant etc.
