Description

Soot filter plate

Technical field

The invention relates to a filter plate, particularly an oil fume filter plate capable of separating oil fume in a gas. Background technique

One of the currently used oil fume filters is a mesh structure, that is, a filter made of a metal mesh or other material is placed on the passage of the oil fume gas. When the oil fume gas passes, the oil fume in the gas contacts the filter screen. The heat is absorbed by the filter, and the oil fume is condensed into liquid oil droplets and attached to the filter, thereby achieving the purpose of separating the oil fume. However, because the filter is composed of many small holes, most of the oil fume passes directly without contacting the filter, so the oil fume separation effect and efficiency are poor; meanwhile, the separated oil droplets adhere to the filter and block the filter over time. The small holes of the mesh increase the air resistance and reduce the oil fume separation effect. At the same time, it is also not conducive to cleaning and further improves the oil fume separation effect. Summary of the Invention

The present invention will be further illustrated by the following description of preferred embodiments of the present invention with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the oil fume filter plate of the present invention includes a front plate 1 and a rear plate 2, the front plate 1 and the rear plate 2 are oppositely disposed and spaced apart from each other, and the air inlet 3 is provided on the front plate 1, and the rear The plate 2 is provided with air outlets 4, and the air inlets 3 and the air outlets 4 are arranged alternately and spaced. The front plate 1 and the rear plate 2 are made of a metal plate, and an aluminum plate is more effective. When the air containing oil fume enters the air inlet 3 due to changes in volume and space, air swirls and vortexes are formed. Due to the dual effects of the air velocity and the swirl and vortex, the oil fume in the air is affected by inertia and centrifugal force. Under action Oil fume filter plate, the heat of the oil fume is absorbed by the oil fume filter plate, the oil fume is condensed into fine oil droplets, is separated out and attached to the oil fume filter plate, and the first oil fume separation is completed; meanwhile, because the air inlet 3 and the air outlet 4 adopt Arranged at intervals, the air changes its flow direction during the process of passing through the fume filter plate and turns back, so that the formed air flows around and strengthens the vortex. Under the dual effects of inertial force and centrifugal force, the oil fume in the air is thrown to the fume filter plate again. To complete the second soot separation.

1 and 2 show a preferred embodiment of the present invention. The oil fume filter plate of the present invention includes a front plate 1 and a rear plate 2. The front plate 1 and the rear plate 2 are oppositely disposed and spaced apart from each other. The front plate 1 An air inlet 3 is provided on the upper side, and an air outlet 4 is provided on the rear plate 2. The air inlet 3 and the air outlet 4 are arranged alternately at intervals. A front wing plate 5 is also provided at the edge of the air inlet 3, and a rear wing plate 6 is provided at the edge of the air outlet 4 of the rear plate 2. The air inlet 3, the front wing plate 5, the rear wing plate 6, and the air outlet The air intake channel 7 where air suddenly turns is formed between 4, and the structure of the above air intake channel 7 can ensure and increase the angle of the air flow to the turn, so that the formation of air circulation and vortices is more sufficient. The distance between the wing plate 5 and the rear wing plate 6 adjusts the air flow rate, so that the oil fume is more easily thrown to the oil fume filter plate by the inertial force and the centrifugal force when the air flow direction changes. The top end 8 of the front wing plate 5 and the top end 9 of the rear wing plate 6 are sharp edges, so that the flow and vortices formed by the air passing there are stronger, thereby greatly increasing the probability of the oil fume contacting the oil fume filter plate. Greatly improved the separation efficiency of oil fume. The included angle o between the front wing plate 5 and the front plate 1 is 30 to 150 °, and the included angle β between the rear wing plate and the rear plate is 30 150 °. Preferably, the included angle a and the included angle β are equal and equal. It is 60 ~ 120 ^Q.

In the above embodiment, the air inlet 3 and the air outlet 4 of the soot filter plate are elongated, the front wing plate 5 is disposed at the edge of the long side of the elongated air inlet 3, and the rear wing plate is disposed at the long Shape the edge of the long side of the air outlet 4.

The air inlet 3 and the air outlet 4 of the present invention may also be round holes, elliptical holes or square holes with matching shapes and sizes. As shown in another embodiment shown in FIG. 3, the front wing plate 5 is provided at this time. At the peripheral edge of the air inlet 3, a rear wing plate 6 is provided at the peripheral edge of the air outlet 4.

As shown in Fig. 1 and Fig. 4, the outer contour of the air inlet surface formed by each of the strip-shaped air inlets 3 may be rectangular, square, circular, or oval. Similarly, the outer contour of the air inlet surface formed by each circular hole, oval hole, or square hole shaped air inlet 3 may also be rectangular, square, circular, or oval.

In order to further improve the separation effect of oil fume, multiple groups of oil fume filter plates can be stacked on top of each other or combined into one according to different application occasions or environmental requirements, making the structure more compact, so that the filtered air contains a large amount of oil fume. Reduced to meet different use occasions Or environmental requirements, actual risk proves that the purification rate of oil fume passing through the air is greater than _80% , which can be applied to various oil fume purification occasions, such as home kitchens, restaurants, restaurants, etc.

It can be known from technical common sense that the present invention can be implemented by other embodiments that do not depart from its spiritual essence or necessary features. Therefore, the above-disclosed implementations are, for all aspects, merely examples, and are not the only ones.
