Description
Technical Field
The invention relates to a filter plate, in particular to an oil fume filter plate capable of separating oil fume from gas.
Background
The oil smoke filter used at present is generally of a net structure, namely a filter screen made of a metal net or other materials is placed on a channel through which oil smoke gas flows, when the oil smoke gas passes, oil smoke in the gas is in contact with the filter screen, heat of the oil smoke is absorbed by the filter screen, and the oil smoke is condensed into liquid oil drops to be attached to the filter screen, so that the purpose of separating the oil smoke is achieved. However, because the filter screen is composed of a plurality of small holes, most of the oil smoke directly passes through the filter screen without contacting with the filter screen, the oil smoke separation effect and efficiency are poor; meanwhile, the separated oil drops are attached to the filter screen, so that the small holes of the filter screen are blocked as long as time passes, the air resistance is increased, the oil smoke separation effect is reduced, and meanwhile, the oil smoke separation device is not beneficial to cleaning and further improving the oil smoke separation effect.
Disclosure of Invention
In order to overcome the defects of poor oil-smoke separation effect and large air resistance of the existing oil-smoke filter, the invention provides an oil-smoke filter plate with good separation effect and small air resistance, and the technical scheme adopted for solving the technical problems is as follows: an oil smoke filter, characterized by: the novel air conditioner comprises a front plate and a rear plate, wherein the front plate and the rear plate are oppositely arranged and spaced, an air inlet is formed in the front plate, an air outlet is formed in the rear plate, and the air inlet and the air outlet are arranged in a staggered and spaced mode.
The oil fume separation device has the beneficial effects of simple structure, low manufacturing cost, good oil fume separation effect, small air resistance, and convenience in cleaning, and can further improve the oil fume separation effect by adopting a method of superposing a plurality of groups of oil fume filter plates in front and back according to different use occasions, and experiments prove that the purification rate of passing oil fume is more than 80%.

Detailed Description
As shown in figures 1 and 2, the lampblack filter plate comprises a front plate 1 and a rear plate 2, wherein the front plate 1
The air inlet and the rear plate 2 are oppositely arranged and spaced, the front plate 1 is provided with an air inlet 3, the rear plate 2 is provided with an air outlet 4, and the air inlet 3 and the air outlet 4 are arranged at intervals in a staggered mode. The front plate 1 and the rear plate 2 are made of metal plates, and the aluminum plate has a better manufacturing effect. Air containing oil smoke forms air circumfluence and vortex due to factors such as volume space change when entering the air inlet 3, oil smoke in the air is thrown to the oil smoke filter plate under the action of inertia force and centrifugal force due to the flow velocity of the air and the dual functions of the circumfluence and the vortex, the heat of the oil smoke is absorbed by the oil smoke filter plate, the oil smoke is condensed into fine oil drops to be separated out and attached to the oil smoke filter plate, and the first oil smoke separation is completed; meanwhile, because the air inlet 3 and the air outlet 4 are arranged at intervals, the air changes the flow direction and turns back in the process of passing through the oil fume filter plate,
the formed air circumfluence and vortex are strengthened, under the double action of inertia force and centrifugal force, the oil smoke in the air is thrown to the oil smoke filter plate again, and the second oil smoke separation is completed.
Example (b): as shown in fig. 1 and 2, the lampblack filter plate comprises a front plate 1 and a rear plate 2, wherein the front plate 1 and the rear plate 2 are oppositely arranged and spaced at a certain distance, an air inlet 3 is formed in the front plate 1, an air outlet 4 is formed in the rear plate 2, and the air inlet 3 and the air outlet 4 are arranged in a staggered and spaced manner. The edge of the air inlet 3 is also provided with a front wing plate 5, the edge of the air outlet 4 of the back plate 2 is also provided with a back wing plate 6, an air inlet channel 7 with air suddenly turning is formed between the air inlet 3, the front wing plate 5, the back wing plate 6 and the air outlet 4, the structure of the air inlet channel 7 can ensure and increase the turning angle of the air flow direction, so that the air streaming and the vortex are more fully formed, meanwhile, the distance between the front wing plate 5 and the back wing plate 6 can be changed to adjust the flow rate of the air, so that the oil smoke is more easily thrown by inertia force and centrifugal force when the air flow direction is changed
Towards oil smoke filter plate. The top 8 of preceding pterygoid lamina 5 and the top 9 of back pterygoid lamina 6 are sharp edge for the air is through the streaming and the swirl intensity that this department formed bigger, thereby greatly increased the probability of oil smoke and oil smoke filter contact, very big improvement the separation efficiency of oil smoke. The included angle a between the front wing panel 5 and the front panel 1 is 30-150 °, the included angle B between the rear wing panel and the rear panel is 30-150 °, preferably the included angle a and B are equal and are both 60-120 °. The air inlet 3 and the air outlet 4 of the oil smoke filter plate are strip-shaped, the front wing plate 5 is arranged at the edge of the long edge of the strip-shaped air inlet 3, and the rear wing plate is arranged at the edge of the long edge of the strip-shaped air outlet 4. The air inlet 3 and the air outlet 4 may also be circular holes, elliptical holes or square holes with mutually adapted shapes and sizes, as shown in fig. 3, at this time, the front wing plate 5 is arranged at the peripheral edge of the air inlet 3, and the rear wing plate 6 is arranged at the peripheral edge of the air outlet 4. As shown in fig. 1 and 4, each of the elongated air inlets 3 is composed of
The outer contour of the air inlet surface can be rectangle, square, round or oval, etc. Similarly, the outer contour of the air inlet surface formed by the circular, elliptical or square air inlets 3 may be rectangular, square, circular or elliptical.
In order to further improve the separation effect of the oil fume, a plurality of groups of oil fume filter plates can be used in a front-back overlapping mode or combined into a whole according to different use occasions or environment requirements, so that the structure of the oil fume filter plate is more compact, the oil fume content of the filtered air is greatly reduced, the oil fume purification rate of the air is more than 80%, and the oil fume filter plate can be applied to various oil fume purification occasions such as family kitchens, restaurants and the like.
