DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-9 This application is described in further detail.

[0027] The embodiment of the present application discloses a gas mixing box for an exhaust gas combustion chamber.

[0028] See also Figure 1 and Figure 2 The gas mixing box includes a gas mixing box body 1, which is a cylindrical structure. A gas mixing tank 11 is formed in the gas mixing box body 1. The high-temperature gas generated during the combustion of the exhaust gas and the external low-temperature air are mixed in the gas mixing tank 11 to reduce the problem of high-temperature gas.

[0029] The gas mixing box also includes a partition 2, which is fixedly connected to the gas mixing box body 1. There are multiple partitions 2 and they are evenly spaced up and down. The partitions 2 divide the gas mixing tank 11 into multiple closed mixing chambers 111 adjacent to each other up and down. In the embodiment of the present application, there are two partitions 2.

[0030] The mixing box 1 is rotatably connected with a rotating shaft 3, which is coaxially arranged with the mixing box 1 and extends in the vertical direction. The rotating shaft 3 passes through the partition 2 and is rotatably connected with the partition 2. Multiple groups of mixing plates 31 are fixedly connected to the peripheral side wall of the rotating shaft 3, each group of mixing plates 31 is located in a mixing chamber 111, and each group of mixing plates 31 has multiple people and is evenly spaced along the circumferential direction. The top wall, bottom wall and side wall of the mixing plate 31 away from the rotating shaft 3 are respectively slidably connected with the partition 2 and the peripheral side wall of the mixing chamber 111, and the mixing chamber 111 is further divided into multiple closed mixing chambers 1111 by the mixing plates 31.

[0031] A hot air pipe 12 and an air pipe 13 are fixedly connected to the gas mixing box 1, and the hot air pipe 12 and the air pipe 13 are connected to the top mixing chamber 111 at the same time. The hot air pipe 12 is connected to the gas outlet of the combustion furnace, and the high-temperature gas generated by the combustion exhaust gas of the combustion furnace is passed into the mixing chamber 111 through the hot air pipe 12. The air pipe 13 is connected to the external air supply system, such as an air pump, and the low-temperature air from the outside is passed into the mixing chamber 111 through the air pipe 13. The hot air pipe 12 is located directly above the air pipe 13, and the hot air pipe 12 and the air pipe 13 are directly facing the position of the mixing plate 31 away from the rotating shaft 3. When in use, the high-temperature gas introduced by the hot air pipe 12 and the low-temperature air introduced by the air pipe 13 impact on the mixing plate 31, driving the rotating shaft 3 to rotate; at the same time, due to the introduction of high-temperature gas and low-temperature air, the air pressure in the mixing chamber 1111 rises.

[0032] A vent hole 21 is formed on the partition 2, and an outlet pipe 14 is fixedly connected to the bottom of the mixing box 1. The outlet pipe 14 is connected to the mixing chamber 111. The vent holes 21 of the upper and lower adjacent partitions 2 and the outlet pipe 14 are staggered along a spiral track. For the same vertically upward mixing plate 31, when the rotating shaft 3 rotates, the mixing plate 31 located at the bottom first passes through the outlet pipe 14, and the mixed and cooled mixed gas in the mixing chamber 1111 of the mixing plate 31 facing away from the forward direction is discharged through the outlet pipe 14, and then when the upper adjacent mixing plate 31 passes through the vent hole 21 on the lower partition 2, the mixing chamber 1111 from which the mixed gas is discharged moves to below the vent hole 21 and is connected. At this time, the mixed gas in the mixing chamber 1111 facing away from the forward direction is passed into the mixing chamber 1111 from which the mixed gas is discharged below, and so on, until the uppermost mixing plate 31 passes through the vent hole 21 of the lower adjacent partition 2, the mixed gas in the uppermost mixing chamber 1111 is discharged into the lower adjacent mixing chamber 1111 through the lower adjacent vent hole 21. The hot air pipe 12 and the air pipe 13 pass the high-temperature gas and the low-temperature air into the uppermost mixing chamber 1111 one by one, and drive the rotation of the rotating shaft 3 to make the mixing chamber 1111 move in the circumferential direction. Under the action of the vent hole 21, it can be continuously transmitted to the lower mixing chamber 1111, and finally discharged through the outlet pipe 14, so that the residence time of the mixed gas in the mixing box 1 is greatly increased, the mixing uniformity of the gas is improved, and the problem of exhausting the gas is reduced.

[0050] The implementation principle of a gas mixing box for an exhaust gas combustion chamber in the embodiment of the present application is: The high-temperature gas generated by the combustion of the exhaust gas in the combustion furnace is introduced into the mixing chamber 1111 through the hot gas pipe 12, and at the same time, the low-temperature air from the outside is introduced into the mixing chamber 1111 through the air pipe 13 to mix with the high-temperature gas and reduce the temperature of the high-temperature gas. When the high-temperature gas and the low-temperature air are introduced, they impact the mixing blades, driving the rotating shaft 3 to rotate, so that the mixed gas is continuously transferred to the mixing chamber 1111 below, and finally discharged through the outlet pipe 14. At the same time, during the rotation of the rotating shaft 3, the stirring blade 41 stirs the mixed gas to improve the mixing uniformity of the mixed gas and reduce the temperature of the high-temperature gas, and the atomizing nozzle 312 sprays water mist to absorb the heat in the mixed gas and further reduce the temperature of the discharged mixed gas.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
