Abstract

The invention provides an oil fume filter plate which can separate the oil fume from gases. The oil fume filter plate is formed by the deformation of a corrugated plate, a plurality of long and narrow rectangular openings are dug on the corrugated plate according to certain intervals and are used as air inlets (air outlets) of the oil fume filtering plate, the part which is not dug becomes an arc-shaped surface and the rectangular surface and the arc-shaped surface form a certain included angle by folding the plate along the long and narrow side of the rectangle. The oil fume filter plate has simple structure and high oil fume separation efficiency; the oil fume separation effect can be improved via superposing a plurality of oil fume filter plates at the front and the back according to different using conditions.

Description

Cooking fume filtering plate

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; Simultaneously because separated oil droplet attached on the screen pack, has just blocked the aperture of screen pack in the course of time, thereby need cleaning and filtering net continually, and the screen pack of matter time used usually to change in one, two year.

Summary of the invention

In order to overcome existing cooking fume filter oil smoke inferior separating effect, short-life deficiency the invention provides a kind of good separating effect, makes simple and durable cooking fume filtering plate.

1, 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: this filter is formed by a corrugated plating deformation, dig out the air inlet of long narrow rectangle hole 2 by certain apart from dashing at interval on the corrugated plating as cooking fume filtering plate, it also is the gas outlet, do not dig partial deformation camber face 1, make rectangle face and arcwall face constitute certain included angle along the long narrow edge contraction of rectangle.

The invention has the beneficial effects as follows: simple in structure, make simple and cost not high, durable, the oil smoke good separating effect and can adopt according to different operating positions before and after the methods of stacked many group cooking fume filtering plates improve the oil smoke separating effect.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 corrugated plating figure of Fig. 1.

Fig. 3 is the local amplification view along the A-A direction of Fig. 1.

The specific embodiment

As Fig. 1, shown in Figure 2, cooking fume filtering plate of the present invention is formed by a corrugated plating deformation, dig out the air inlet of long narrow rectangle hole 2 by certain apart from dashing at interval on the corrugated plating as cooking fume filtering plate, it also is the gas outlet, do not dig partial deformation camber face 1, make rectangle face and arcwall face constitute certain included angle along the long narrow edge contraction of rectangle.Corrugated plating adopts metallic plate to make, and makes better effects if with aluminium sheet, and the front is plated one deck titanium or titanium silver again.

The air that contains oil smoke collides with arcwall face before entering air inlet, the part heat of oil smoke is absorbed by arcwall face, the part oil smoke is frozen into promptly that little oil droplet is separated and attached on the arcwall face, because arcwall face is uneven, all the other oil smoke scattering collisions, and some oil smoke and follow-up oil smoke also will collide; Air streams air and eddy current because the factors such as variation of volume space form before by air inlet, owing to the flow velocity of air, stream the effect with eddy current, make the oil smoke that collides under inertia force and action of centrifugal force, repeatedly thrown on the arcwall face, the heat of oil smoke is repeatedly absorbed by arcwall face, and the effect that oil smoke separates is quite remarkable.

Air is by behind the air inlet (gas outlet), finishes and the separating of above-mentioned same principle, and the efficient that oil smoke separates further improves.

Here hydrodynamics-collision effect method principle and aerodynamic principle are organically combined, make probability that oil smoke contacts with arcwall face near 100%.

Embodiment: as Fig. 1, shown in Figure 2, cooking fume filtering plate of the present invention is formed by a corrugated plating deformation, dig out the air inlet of long narrow rectangle hole 2 by certain apart from dashing at interval on the corrugated plating as cooking fume filtering plate, it also is the gas outlet, do not dig partial deformation camber face 1, make rectangle face and arcwall face constitute certain included angle along the long narrow edge contraction of rectangle.The angle here can guarantee and strengthen the air angle of turnover suddenly less than 30 °, and it is more abundant that air is streamed with the formation of eddy current, improved the separative efficiency of oil smoke greatly.

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.
