[0021] The present utility model provides a tunnel drying furnace for treating high-concentration organic waste gas as Figures 1-4 shown, which includes a drying box body 1. A heating component is arranged inside the drying box body 1. A conveying member for material conveying is arranged on the top of the heating component. A recovery component for waste gas recovery is arranged on the top of the drying box body 1. The recovery component includes a recovery pipe 7 inserted and connected to the top of the drying box body 1. One end of the recovery pipe 7 is provided with a first fan 8. The output end of the first fan 8 is provided with a conveying pipe 14 for conveying the waste gas to the heating component. An exhaust cylinder 10 for exhausting gas is inserted and connected to the top of the drying box body 1. A baffle 9 for blocking gas is arranged between the recovery pipe 7 and the exhaust cylinder 10. The baffle 9 is fixedly connected to the inner wall of the top end of the drying box body 1.

[0022] It should be noted that holes for material inlet and outlet are respectively formed on both sides of the set drying box body 1. The set conveying member is inserted and connected in the holes. During use, the product is driven by the conveying member to enter and exit the drying box body 1 through the holes. The set first fan 8 is a centrifugal fan, which sucks air from the air inlet and accelerates and rotates in the centrifugal impeller, and finally sprays the high-speed air out of the centrifuge to form a wind direction. The set first fan 8 is fixedly connected to the top of the drying box body 1. When it is necessary to exhaust the waste gas in the drying box body 1, the first fan 8 is turned on. The first fan 8 extracts the waste gas located in the drying box body 1 through the recovery pipe 7 and conveys the extracted waste gas to the heating component through the conveying pipe 14. The set baffle 9 is used to block the movement of the waste gas to the side of the exhaust cylinder 10. During use, the movement of the waste gas to the side of the exhaust cylinder 10 is reduced. The set exhaust cylinder 10 is used to exhaust the waste gas from the drying box body 1.

[0023] Specifically, the conveying member includes a conveying structure 2 inserted and connected to the middle of the drying box body 1.

[0024] It should be noted that the set conveying structure 2 can be a belt conveyor or the like, which is used to convey the product into the drying box body 1 during use, dry the product through the heating component, and convey the dried product out of the drying box body 1 through the conveying structure 2.

[0025] Specifically, the heating component includes a combustion chamber 3 fixedly connected to the inner wall of the bottom end of the drying box body 1. A burner 11 is arranged on one side of the drying box body 1. A hot gas transmission member is arranged on the other side of the combustion chamber 3. The hot gas transmission member includes an air outlet pipe 12 arranged on one side of the combustion chamber 3. One end of the air outlet pipe 12 far away from the combustion chamber 3 is provided with a second blower 13. The second blower 13 is fixedly connected to the inner wall of the bottom end of the drying box body 1. The output end of the second blower 13 is provided with a heat delivery pipe 4. A plurality of first uniform air distribution plates 5 are arranged at the bottom of the conveying structure 2. The front and back of the first uniform air distribution plate 5 are respectively fixedly connected to the inner walls of the front and back of the drying box body 1. A plurality of second uniform air distribution plates 6 are arranged between the recovery pipe 7 and the conveying structure 2. The front and back of the second uniform air distribution plate 6 are respectively fixedly connected to the inner walls of the front and back of the drying box body 1.

[0026] It should be noted that the arranged combustion chamber 3 is fixed inside the drying box body 1. One end of the conveying pipe 14 far away from the first blower 8 is inserted and fixedly connected to the front of the combustion chamber 3, which is used to convey the high-concentration organic waste gas extracted from the drying box body 1 into the interior of the combustion chamber 3. The burner 11 arranged on one side of the combustion chamber 3 is a natural gas burner. A natural gas burner is a device that converts natural gas into available heat energy. Its working principle is mainly based on the combustion reaction. Natural gas is mixed with air and ignited to release a large amount of heat energy. High-concentration organic waste gas is conveyed through the conveying pipe 14 at the flame outlet of the burner 11. By using the high-concentration organic waste gas as a combustion aid, the organic waste gas can be effectively treated, the waste gas emission can be reduced, the energy in the waste gas can be fully utilized, the combustion efficiency can be improved, and the use of fossil fuels such as natural gas can be reduced; the working principle of the arranged second blower 13 is the same as that of the first blower 8. The hot gas in the combustion chamber 3 is exhausted through the air outlet pipe 12 at its input end, and then the hot gas is conveyed to the bottom of the first uniform air distribution plate 5 through the heat delivery pipe 4 at the output end of the second blower 13; the first uniform air distribution plate 5 evenly distributes the input air or gas to the target area. The uniform air distribution plate has one or more air inlets for receiving gas from the outside. Channels are designed inside the plate, and the channels can be evenly arranged holes to ensure that the gas can pass through evenly.
