DETAILED DESCRIPTION

[0020] To make the above features and advantages of the present utility model more understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings. However, the present utility model is not limited thereto.

[0021] Reference Figures 1 to 5

[0022] A swirl spray flue gas treatment device includes a tower body 20. An air inlet pipe 21 connected to a flue gas suction device 10 in the workshop is provided on the lower side wall of the tower body. At least two layers of swirl plates 30 are arranged at intervals from bottom to top in the tower body. A spray mechanism is provided above each swirl plate in the tower body. A funnel-shaped liquid outlet pipe 22 is provided at the lower part of the tower body. A barrel-shaped liquid collecting tank 23 located below the liquid outlet pipe is provided at the bottom of the tower body. An air outlet pipe 24 is provided at the top of the tower body, and the air outlet pipe is connected to an air extraction device. The flue gas generated by cooking items in the workshop is discharged into the tower body through the flue gas suction device, and the air is extracted outward through the air extraction device. The flue gas passes through the swirl plates layer by layer and is sprayed by the spray mechanism to eliminate oil and other substances in the flue gas. The liquid mixed with the oil after spraying enters the barrel-shaped liquid collecting tank through the liquid outlet pipe for collection.

[0023] In this embodiment, in order to better extract the flue gas in the workshop, the flue gas suction device includes a cylindrical suction hood 11 hoisted on the workshop ceiling. A rotating blade 12 driven by a motor is provided at the top of the inner cavity of the suction hood. A smoke outlet 13 is provided on one side of the top of the suction hood. A truncated cone-shaped mesh cover 14 is provided below the rotating blade in the suction hood. So that the flue gas can be sent from the smoke outlet through the rotating blade and enter the tower body through the pipeline.

[0024] In this embodiment, since part of the oil or liquid in the flue gas will slide down through the mesh cover after the rotating blade stops working, in order to collect this part of the liquid or oil, an oil collecting port 15 is provided at the center of the bottom of the mesh cover, and a detachable oil collecting box 16 is screwed on the oil collecting port. Thus, the oil is prevented from falling into the lower cooking mechanism.

[0025] In this embodiment, since some water droplets will condense on the inner wall of the suction hood after the rotating blade stops working, in order to prevent the water droplets from falling, a circular L-shaped flange 17 is provided on the lower inner wall of the suction hood. An annular liquid collecting tank 18 with a U-shaped cross-section is formed by the cooperation between the L-shaped flange and the inner wall of the suction hood. A drain pipe 19 with a valve is provided at the bottom surface of the annular liquid collecting tank. Thus, the condensed water droplets are collected for centralized discharge.

[0026] In this embodiment, the swirl plate includes a plurality of inclined blades 31 uniformly arranged along the circumferential direction. An angle is formed between the inclined blades and the horizontal plane, and a swirl channel 32 is formed between adjacent two blades, which helps to uniformly spray the flue gas inside the tower body.

[0027] In this embodiment, the spray mechanism includes spray heads 41 arranged at intervals on the side wall of the tower body along the circumferential direction, and the spray heads are connected to the liquid inlet pipe 42 via a pipeline.

[0028] In this embodiment, a liquid storage tank 40 connected to the lower side wall of the barrel-shaped liquid collecting tank is provided on one side of the tower body, a circulating pump 43 is installed on the liquid storage tank, the liquid outlet of the circulating pump is connected to the liquid inlet pipe of the spray mechanism through a pipeline, and a sewage pipe 44 is provided on the side wall of the liquid storage tank and the bottom side wall of the barrel-shaped liquid collecting tank. After a period of use, the liquid in the liquid storage tank and the barrel-shaped liquid collecting tank is discharged through the sewage pipe, and the barrel-shaped liquid collecting tank and the inner wall of the tower body can be cleaned, and the impurities in the barrel-shaped liquid collecting tank need to be fished out every day.

[0029] In this embodiment, a screen 25 is installed in the air outlet pipe, and a plurality of multi-faceted hollow balls 26 are placed on the upper side of the screen to achieve demisting. A plurality of observation windows 27 covered with transparent plates are arranged from top to bottom on the tower body, and a hollow portion 28 is arranged at the connection between the lower part of the tower body and the barrel-shaped liquid collecting tank to observe the collection situation of the barrel-shaped liquid collecting tank.
