[0034] Specifically, the second air inlet 10 has a square-round joint 2 installed inside, and the end of the square-round joint 2 is connected to a high-temperature valve 3 with a mixing device 7.
[0035] The high-temperature valve 3 is located at the end of the square section 2. The high-temperature valve 3 is located on the air duct of the first air inlet 8, which directly cools the high-temperature regulating valve (i.e., the high-temperature valve 3), extends the service life of the high-temperature valve, and effectively ensures that the valve is maintained at a low leakage index. The opening and closing of the high-temperature valve is related to the furnace temperature.
[0036] The air mixing device 7 is installed on the high-temperature valve 3. The air mixing device 7 has several through holes, such as a perforated plate with a certain air permeability. When the high-temperature gas from the incinerator is discharged (e.g., entering the housing 1 from the second air inlet 10), the high-temperature gas mixes with the low-temperature gas and impacts the air mixing device 7, causing the mixed gas to form turbulence, thereby achieving uniform mixing. This also effectively reduces the overall resistance drop of the mixer.

[0040] Specifically, the low-temperature gas enters from the first air inlet 8, and the high-temperature gas enters from the second air inlet 10, since the high-temperature valve 3 is located in the air duct of the first air inlet 8, the low-temperature gas can effectively reduce the temperature of the high-temperature valve 3, and effectively prolong the service life of the valve.
[0041] The mixing device is square or close to square, the overall size is small, the mixer can be installed vertically or horizontally, the position height of the high-temperature valve is effectively reduced, the maintenance is facilitated, and the resistance drop of the whole high-low temperature mixer is small; the gas of the high-temperature discharge port of the incinerator system can be uniformly mixed with the low-temperature discharge port gas, the damage of high temperature to subsequent equipment is reduced; the high-temperature regulating valve (high-temperature discharge) is arranged in the mixer, that is, the high-temperature valve is located in the air duct of the first air inlet, the low-temperature port gas of the incinerator directly cools the high-temperature regulating valve, the service life of the high-temperature valve is prolonged, and the valve is effectively ensured to maintain a small leakage index. The high-temperature valve is arranged in the mixer, the service life of the valve is effectively prolonged, the internal structure of the mixer is adjusted, the high-temperature tail gas is fully mixed with the low-temperature tail gas, and the influence of the high-temperature tail gas on subsequent equipment is reduced.
