Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0021] Please refer to Figures 1-4 The waste gas device of the present application comprises a heat storage device 1 and an incineration device 2, and the left side of the incineration device 2 is provided with an auxiliary mechanism 4.

[0022] The heat storage device 1 is internally provided with three heat storage cavities 3, the bottom of each of the three heat storage cavities 3 is provided with a connecting pipe 8, the bottom of each of the three connecting pipes 8 is provided with a main pipe 7, one end of the main pipe 7 is provided with a fan 6, and each of the three heat storage cavities 3 is provided with an installation pipe between the heat storage cavity 3 and the incineration device 2, and each of the three installation pipes is provided with a valve. The waste gas enters the remaining connected heat storage cavities 3 from the main pipe 7 through one of the connecting pipes 8 by the fan 6, the heat storage cavities 3 are filled with heat storage materials such as ceramic heat storage bodies, and these heat storage materials can absorb and store the heat energy in the waste gas. When the waste gas passes through the heat storage cavities 3, the heat energy is absorbed by the heat storage materials, and the waste gas itself is preheated. The preheated waste gas enters the incineration device 2 from the installation pipe, mixes with the combustion air in the incineration device 2, and is fully combusted. The heat generated during the combustion process enters another heat storage cavity 3 of the heat storage device 1, and the process is repeated to realize waste gas treatment and utilization.

[0023] The auxiliary mechanism 4 comprises an installation box 401, the left side of the incineration device 2 is fixedly provided with the installation box 401, the left side of the installation box 401 is fixedly provided with a motor 402, the output shaft of the motor 402 is fixedly provided with a driving gear 403, the outer surface of the driving gear 403 is engaged with a driven gear 404, the inside of the driven gear 404 is fixedly provided with a rotating rod 405 extending into the inside of the incineration device 2, the outer surface of the rotating rod 405 is fixedly provided with a blade 406, the inside of the rotating rod 405 is provided with a water storage cavity 407, the outer surface of the water storage cavity 407 is provided with a water spraying hole 408, and the inside of the water spraying hole 408 is provided with a filter screen 409.

[0024] The motor 402 drives the rotating rod 405 to rotate, and the rotation of the rotating rod 405 drives the blade 406 to rotate. The rotation of the blade 406 can increase the flow speed of the exhaust gas, so that the exhaust gas can be quickly and uniformly diffused, which is helpful for the full combustion and mixing of the exhaust gas. At the same time, the rotation of the rotating rod 405 can spray water from the water injection hole 408 in the water storage cavity 407, increase the humidity of the exhaust gas, prevent the generation of pollutants such as nitrogen oxides, and cause secondary pollution to the environment. The filter screen 409 inside the water injection hole 408 is used to prevent impurities from blocking the water injection hole 408, and to ensure the normal operation of the water injection function. The top of the incineration equipment 2 is provided with a humidity sensor, and the probe of the humidity sensor extends into the inside of the incineration equipment 2. When the humidity sensor detects that the humidity in the incineration equipment 2 is too high or too low, the water pump 502 can be controlled to humidify or cool, so as to keep the humidity in the equipment within a suitable range. This not only helps to improve the stability and efficiency of the incineration process, but also effectively prevents equipment failure or safety problems caused by excessive or insufficient humidity.

[0025] The left side of the auxiliary mechanism 4 is provided with a water supply device 5, which includes a water storage tank 501. The top of the water storage tank 501 is provided with a water pump 502. The input end of the water pump 502 is connected with a water suction pipe between the water storage tank 501. The output end of the water pump 502 is connected with a water supply pipe. One end of the rotating rod 405 is rotatably connected with the right inner wall of the incineration equipment 2, and the other end of the rotating rod 405 is provided with a rotary joint 503. The rotating rod 405 is connected with the water supply pipe through the rotary joint 503. The water pump 502 introduces the water source in the water storage tank 501 into the water storage cavity 407 of the rotating rod 405 through the water suction pipe and the water supply pipe. The rotary joint 503 is arranged to facilitate the rotation of the rotating rod 405.

[0026] In implementation, the following steps are taken:

[0027] 1) Start the fan 6, introduce the exhaust gas into one of the connecting pipes 8 through the main pipe 7, and then into the heat storage cavity 3 connected with the connecting pipe 8. The exhaust gas is heated by the heat storage material in the heat storage cavity 3 and is preheated. The preheated exhaust gas enters the incineration equipment 2 through the installation pipe;

[0028] 2) Then in the incineration equipment 2, the preheated exhaust gas is mixed with the combustion air and fully combusted. At the same time, the motor 402 is started to drive the driving gear 403 to rotate, and then drive the driven gear 404 and the rotating rod 405 to rotate. The blades 406 on the outer surface of the rotating rod 405 stir the gas in the incineration equipment 2 with the rotation of the rotating rod 405, so that the exhaust gas can be quickly and uniformly diffused, and the combustion efficiency is improved;

[0029] 3) When the humidity sensor monitors that the humidity needs to be reduced, the water pump 502 is started, the water source in the water storage tank 501 is sent into the water storage cavity 407 of the rotating rod 405 through the water suction pipe and the water delivery pipe and sprayed out through the water spraying hole 408, the humidity in the incineration equipment 2 is increased, and the generation of pollutants such as nitrogen oxides is prevented;

[0030] 4) The heat generated in the last combustion process is partially used to maintain the incineration process, and partially enters another heat storage cavity 3 through another connecting pipe 8 to realize heat recovery and reuse.

[0031] In summary, the device for treating multi-specification waste gas by using heat accumulation type combustion can drive the rotating rod 405 and the blade 406 to rotate through the motor 402, and under the rotation of the blade 406, the flow speed and diffusion uniformity of the waste gas in the incineration equipment 2 are increased, so that the waste gas can be more fully mixed with the combustion air and burned, thereby improving the efficiency of waste gas treatment.

[0032] Further, the water is sprayed into the incineration equipment 2 through the water spraying hole 408, the humidity of the waste gas is increased, the generation of nitrogen oxides in the combustion process is effectively prevented, and secondary pollution to the environment is reduced.
