Abstract
Description
Technical Field

[0002] In industrial production, a large amount of waste gas will be generated, and there will be unburned substances in the waste gas. It is necessary to burn the unburned substances in the waste gas through combustion to prevent the waste gas from polluting the external environment. Therefore, a waste gas combustion furnace is needed to burn the waste gas. In the process of waste gas combustion, a large amount of heat is generally generated, and the heat is easily dissipated into the air, resulting in a large amount of energy waste, so it is inconvenient to fully utilize the energy generated by the combustion of the waste gas. At the same time, when the waste gas is treated in a low-temperature environment, the temperature of the waste gas is low, which makes it easy for the waste gas to still not burn fully, and it is inconvenient to fully treat the waste gas. There is still a large amount of dust or pollutants in the existing waste gas, which is easy to cause environmental pollution if it is directly discharged into the environment. The existing waste gas combustion furnace lacks an absorption structure for dust and other substances in the waste gas, which makes it inconvenient to use the waste gas combustion furnace and treat the waste gas.

[0031] Specifically, when the exhaust gas is burned, the exhaust gas enters the middle pipe 7 through the air intake block, and enters the combustion box 1 through the air intake port 8 from the middle pipe 7.

[0032] In summary, when used as a whole:
[0033] When the exhaust gas is burned, the exhaust gas enters the middle pipe 7 through the air intake block, and enters the combustion box 1 through the air intake port 8 from the middle pipe 7. The exhaust gas burns inside the combustion box 1. The heat generated during the combustion process is absorbed by the water in the water tank 4, thereby heating the water in the water tank 4. The burned exhaust gas enters the water tank 4 through the exhaust pipe 9. The water in the water tank 4 absorbs the remaining heat in the exhaust gas again. The pollutants in the exhaust gas are absorbed by the water. The exhaust gas after the pollutants are absorbed is discharged from the air outlet 15 opened on the upper cover 3, completing the combustion of the exhaust gas.
[0034] When utilizing the heat generated by combustion, the water in the water storage tank 4 absorbs the energy generated by combustion, so that during the combustion of the exhaust gas, the heat is transferred to the location where the heat is needed through the connection with the external water circulation system.
[0035] When air is taken in under low temperature environment, the exhaust gas is passed into the water in the water storage tank 4 through the exhaust pipe 9. There is still heat in the exhaust gas after combustion, and the remaining heat in the exhaust gas is absorbed by the water. At the same time, through the intermediate pipe 7 provided in the water storage tank 4, when the exhaust gas to be burned enters the intermediate pipe 7 from the intake pipe 6, the heat in the water storage tank 4 heats the exhaust gas entering the intake pipe 6, so that the exhaust gas is heated and can quickly reach the combustion temperature when the external temperature is low, thereby facilitating the full combustion of the exhaust gas.
