Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further explained with reference to the accompanying drawings. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1 to fig. 4, the present embodiment provides an oil smoke purification apparatus, which includes a first flue, an oil smoke purifier, and a second flue that are sequentially communicated; the first flue is also communicated with the air outlet of the public flue;

the second flue comprises a pipeline body and a plurality of guide vanes; the bottom ends of the guide vanes are fixedly connected with the inner wall of the pipeline body, the guide vanes are uniformly distributed in a plurality of layers of circumferences along the axial direction of the pipeline body, and the guide direction is anticlockwise arranged along the radial direction of the pipeline body; the height of the guide vane is gradually reduced along the oil smoke discharge direction; the symmetrical center line of the cross section of the guide vane is a sine curve. When a plurality of air outlets of the public flue are arranged, only one air outlet can be left and other air outlets can be blocked; and when the outlet is too small, the opening of the outlet needs to be enlarged. In some preferred embodiments, the outlet is 400mm by 400mm in size and is in communication with the first conduit via a transition conduit. The oil fume purifier is oil fume purifying equipment commonly used in the field, such as an electrostatic oil fume purifier with the specification model of a pioneer brand JH-DD 301-4A.

The cross-sectional shape of the pipe body is preferably circular. The number of the distribution layers of the guide vanes in the axial direction of the pipeline body is determined by the length of the pipeline body, and in some preferred embodiments, in order to reduce the number of the arrangement layers of the guide vanes on the basis of ensuring a better smoke exhaust effect, the interval between the guide vanes in multiple layers is 400-600mm, preferably 500mm; every layer the quantity of guide vane is 8, and evenly respectively on the circumference, and the contained angle of two adjacent guide vane and pipeline body axle center on same layer is 45 promptly.

When the oil smoke purifier is used, the oil smoke purifier extracts oil smoke in the public flue through the first flue, the treated oil smoke purifier is discharged into the second flue, when smoke flows through the section of pipeline, the air close to the guide vanes on the outer side rotates in the anticlockwise direction due to the guide effect of the vanes, the air closer to the center is gradually driven to form cyclone with certain centrifugal force, and the multilayer guide vanes arranged at intervals can strengthen and maintain the cyclone. Therefore, the oil smoke particles in the smoke have higher density than air, and gradually separate from the center of the pipeline under the action of centrifugal force, are thrown to the periphery of the cyclone, are captured by the inner wall of the pipeline and are condensed into liquid oil drops. Finally, the separation of oil smoke particles is realized, and the oil smoke purifier and the flue are matched to ensure that the system can obtain higher oil smoke purification rate.

In some preferred embodiments, in order to reduce wind noise and wind resistance as much as possible, the height variation of the blade is considered to be set to be a smooth curve, and specifically, the curve equation of the height variation line of the guide blade is as follows: { x =100 × t; z =50 × sin (t × 90-90) +50}; wherein t is from [0,1]. In other preferred embodiments, in order to enhance the flow guiding effect and make the cyclone centrifugal force generated when the oil fume passes through stronger, the curve equation of the symmetrical central line of the cross section of the flow guiding vane is as follows: { x =100 × t; z =50 × sin (t × 90-90) +50}. It should be understood that the flow guiding directions of all the guide vanes are the same, and the number and the positions of the two adjacent layers of guide vanes are in corresponding relation, preferably, the two adjacent layers of guide vanes are respectively on the same straight line which is axially parallel to the pipeline body. In order to achieve better flow guiding effect, the height of the highest point of the flow guiding blade is 1/20-1/30 of the inner diameter of the pipeline body.

In other preferred embodiments, consideration needs to be given to more conveniently collecting the liquid grease condensed on the inner wall surface of the pipeline body, and when the oil fume purification device is placed horizontally, an oil collecting hole can be formed in the lower side of the pipeline body, so that the liquid grease condensed on the inner wall surface of the pipeline body automatically collects at the oil collecting hole and flows out of the oil fume purification device under the action of gravity, and then is further processed by other purification equipment; when the oil smoke pipeline is vertically arranged, an unpowered hood can be arranged at the tail end of the pipeline body, and the rotation direction of the unpowered hood is matched with the flow guide direction of the flow guide blades, so that the discharge wind resistance is further reduced.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
