[0025] The following will be combined Figure 1-4 , an exhaust system for a tunnel oven involved in the embodiment of the present application is described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application. In order to better illustrate the present application, it is applied to an exhaust system for a tunnel oven for detailed description below.

[0026] Embodiment 1:

[0027] See also Figure 1-4 As shown, an exhaust system for a tunnel oven comprises: a water collection and treatment device 5, a first gas flow control device 9, an exhaust treatment device 8, a Venturi variable air volume device 3, and a clean air supply device 6. The water collection and treatment device 5 is used to collect the hot air from the heating section of the tunnel oven, cool the hot air, and precipitate condensed water; the first gas flow control device 9 is used to collect the exhaust air from the cooling section of the tunnel oven, and merge it with the air coming out of the water collection and treatment device 5 to form a first mixed gas; the exhaust treatment device 8 is used to discharge a part of the first mixture to the outside; the Venturi variable air volume device 3 is used to collect the exhaust air from the preheating section of the tunnel oven, and merge it with the remaining part of the first mixture to form a second mixed gas; the clean air supply device 6 is used to mix the second mixed gas with outdoor fresh air and then enter the heating section of the tunnel oven.

[0028] A second gas flow control device 10 is provided on the pipeline between the water collection treatment device 5 and the heating section of the tunnel oven. A first venturi constant air volume device 4 is provided on the pipeline for conveying the first mixed gas; a second venturi constant air volume device 12 is provided on the pipeline for the clean air supply device 6 to supply air to the tunnel oven. The clean air supply device 6 can be an air conditioning unit, and the exhaust air treatment device 8 can be a fan with a filter. Both are commonly used components in the existing clean fresh air industry.

[0029] The water collection and treatment device 5 includes: a box body, an air inlet 16, an air outlet 13, a gas processing device 14, and a gas-liquid diversion device 15. A penetrating installation cavity is provided in the box body; the air inlet 16 is arranged at one end of the installation cavity; the air outlet 13 is arranged at the other end of the installation cavity; the gas processing device 14 is arranged on the side of the installation cavity close to the air outlet 13, and is used to adsorb impurities in the gas; the top of the gas-liquid diversion device 15 is rotatably connected to the box body through a connecting part; the top of the gas-liquid diversion device 15 is rotatably connected, which is convenient for fine-tuning according to the length of the air inlet 16 during actual installation, so as to facilitate installation.

[0030] The gas-liquid flow separation device 15 is obliquely disposed in the installation cavity and is located below the gas processing device 14 , and is used to separate the condensate flowing back onto the gas-liquid flow separation device 15 from the gas.

[0031] When the tunnel oven is running, the hot air in the heating section enters the water collection and treatment device 5 through the second gas flow control device 10 (with memory function). The hot air enters the water collection and treatment device 5 through the air inlet 16. The temperature of the hot air will be reduced when passing through the gas-liquid diverter 15. When the hot air continues to meet or pass through the gas treatment device 14 upward, the temperature of the hot air will drop rapidly, and condensed water will be precipitated at the same time. After a certain amount of condensed water is accumulated, it will drip into the gas-liquid diverter 15 under the action of gravity, slide down along the gas-liquid diverter 15 and then be collected.

[0032] The exhaust air of the cooling section passes through the first combined return air port 2, passes through the first gas flow control device 9 (with memory function), and merges with the air coming out of the air outlet of the water collection treatment device 5. The air flow rate is controlled by the first Venturi constant air volume device 4. A part of the air is discharged outdoors through the exhaust treatment device 8, and the other part enters the clean air supply device 6 with the air passing through the Venturi variable air volume device 3. The outdoor fresh air enters the clean air supply device 6 and merges with the return air, and then passes through the second Venturi constant air volume device 12 from the negative pressure double-sealed high-efficiency air supply port 1 to enter the heating section. The exhaust air of the preheating section passes through the second combined return air port 11, passes through the Venturi variable air volume device 3, and merges with a part of the exhaust air of the heating section and the cooling section. Enter the clean air supply device 6.

[0033] In order to better realize the system adjustment, the exhaust system also includes a controller 7, which is respectively connected to the exhaust treatment device 8, the first gas flow control device 9, the second gas flow control device 10, the clean air supply device 6, and the venturi variable air volume device 3. The controller 7 captures the temperature and humidity of the tunnel oven, and controls the air volume, temperature, humidity, and pressure difference through the venturi variable air volume device 3, the first gas flow control device 9 (with memory function), the second gas flow control device 10 (with memory function), the exhaust treatment device 8, and the clean air supply device 6.

[0034] The second gas flow control device 10 (with memory function) controls the amount to avoid the temperature in the heating section being too high or too low. The first venturi constant air volume device 4, the second venturi constant air volume device 12 and the venturi variable air volume device 3 adjust the pressure difference to maintain the positive pressure in the oven. The first venturi constant air volume device 4 and the venturi variable air volume device 3 can ensure the stability of the pressure difference in the room.

[0035] In some embodiments, the gas processing device 14 includes an installation slide 18 disposed in the installation cavity and a filter layer 19 slidably installed in the installation slide 18. This structure allows for regular replacement of the filter layer 19. The filter layer 19 is an activated carbon filter layer 19 or a glass fiber filter layer 19, which can remove harmful components in the gas.

[0036] In some embodiments, the gas-liquid diversion device 15 includes a guide plate, which is tilted and has a plurality of through holes 20 that penetrate the guide plate. The through holes 20 are tilted and arranged in a rectangular array. The aperture of the through holes 20 is 1-5 mm, preferably 5 mm. The high end of the through hole 20 is located on the high end side of the guide plate, and the low end of the through hole 20 faces the low end side of the guide plate. In this structure, high-temperature gas with high water content can pass through, and condensed water will not flow away from the through hole 20 when falling, because the through hole 20 is also tilted, thereby achieving diversion and further achieving gas-liquid diversion.

[0037] In some embodiments, the upper surface of the guide plate is provided with a plurality of guide grooves 22, and the cross section of the guide grooves 22 is arc-shaped. The guide grooves 22 are provided between adjacent rows of through holes 20. The arc-shaped guide grooves 22 are provided on the surface of the guide plate to facilitate the condensed water dripping onto the upper surface of the guide plate to flow into the waste liquid collection chamber 21 for collection.

[0038] In some embodiments, a waste liquid collection chamber 21 is formed between the guide plate, the side wall of the box body, and the air inlet 16. The waste liquid collection chamber 21 is used to collect condensed liquid guided from the guide plate, and a waste liquid discharge port 17 is provided at the lower part of the waste liquid collection chamber 21. The collection and discharge of condensed water is realized to prevent it from corroding and polluting the pipeline system.

[0039] The above description is only a preferred embodiment of the present invention and is used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
