The space in the main body 1 is divided into three areas from bottom to top, namely an air flow area 11, a heat exchange area 12 and a combustion area 13, wherein the air flow area 11 is used for inflow of external air and exhaust of burnt air, the heat exchange area 12 is used for recovering heat in the burnt air and preheating the inflow air, and the combustion area 13 is used for fully burning the preheated air.
The intake and exhaust module 2 is located in the airflow zone 11, the heat exchange module 3 is located in the heat exchange zone 12, and the burner 41 is fixedly mounted on the main body 1 and located in the combustion zone 13, which will be further described with reference to specific structures.
Referring to fig. 2, the intake and exhaust module 2 mainly comprises an intake chamber 21, an intake pipe 22, an exhaust chamber 23, and an exhaust pipe 24, wherein the intake chamber 21 and the exhaust chamber 23 are both located in the airflow zone 11, one end of the intake pipe 22 enters the main body 1 and is connected with the intake chamber 21 for guiding the gas to be treated into the intake chamber 21, and one end of the exhaust pipe 24 enters the main body 1 and is connected with the exhaust chamber 23 for guiding the gas burned in the exhaust chamber 23 out of the main body 1.
Referring to fig. 1, the heat exchange module 3 mainly comprises a heat exchange device 31 and a driving device 32, wherein the driving device 32 is located outside the main body 1, one end of the driving device 32 extends into the main body 1 and is connected with the heat exchange device 31, the driving device is configured to drive the heat exchange device 31 to rotate, and the heat exchange device 31 is fixedly installed on one end of the driving device 32 extending into the main body 1 or is rotationally connected to the inner wall of the main body 1, and can rotate under the driving of the driving device 32.
In some possible implementations, the driving device 32 is composed of a rotating shaft, a motor, a speed reducer, and the like, one end of the rotating shaft extends into the main body 1, the motor and the speed reducer are located below the main body and are used for driving the rotating shaft to rotate, an output end of the motor is connected to an input end of the speed reducer, and an output end of the speed reducer transmits power output by the motor to the rotating shaft in a coupling or gear transmission mode.
In some possible implementations, the heat exchange device 31 may be composed of a bracket and a heat accumulator, where the bracket is fixedly mounted on the rotating shaft, and the heat accumulator is placed on the bracket, and when the rotating shaft rotates, the bracket and the heat accumulator can be driven to rotate together.
Referring to fig. 1, the first sealing air tap 51, the second sealing air tap 52 and the third sealing air tap 53 are fixedly installed on the main body 1, and the air injecting ends of the three sealing air taps are located in the main body 1 to form three air barriers for sealing, and the three sealing air taps are described below with reference to the actual structure and function.
The number of first sealing air nozzles 51 is plural, and the first sealing air nozzles 51 are circularly arrayed on the main body 1 around the axis of the main body 1 and are used for forming a first air seal, and a gas barrier is formed between the heat exchange area 12 and the combustion area 13.
It will be appreciated that the combustion zone 13 is subjected to an oxidation reaction which releases a significant amount of heat during the reaction, while the heat exchange zone 12 is mainly subjected to heat storage and heating, and that these two zones are not subject to mutual interference, the heat generated during the combustion process should be concentrated into the heat storage zone and then transferred to the heat exchange zone by the heat exchange means 31.
The air source needed by the first sealing air tap 51 is provided by a first air supply unit 54, the first air supply unit 54 is fixedly arranged on the main body 1, the input end of the first air supply unit 54 is connected with the air inlet part of the air inlet and outlet module 2, and the output end of the first air supply unit is connected with the first sealing air tap 51 and is used for providing the air to be combusted to the first sealing air tap 51 so that the first sealing air tap 51 forms a first air barrier.
Since most of the gas emitted from the first sealing nozzle 51 enters the combustion zone 13, it is necessary to use gas which has not undergone combustion treatment, because if burned gas is used, flameout due to a decrease in the concentration of volatile organic compounds in the combustion zone 13 may be caused.
The number of second sealing air nozzles 52 is plural, and the second sealing air nozzles 52 are circularly arrayed on the main body 1 around the axis of the main body 1 and are used for forming a second air seal, and a gas barrier is formed between the first air seal and the heat exchange area 12.
It will be appreciated that some of the gas emitted from the first sealing nozzle 51 may enter the heat exchange zone 12, which is obviously not permissible, as it may result in an off-specification exhaust. The use of the second sealing tap 52 to form a gas barrier serves to prevent gas from the first sealing tap 51 from entering the heat exchange zone 12.
The number of the third sealing air nozzles 53 is plural, and the third sealing air nozzles 53 are circularly arrayed on the main body 1 around the axis of the main body 1 and are used for forming a third air seal, and a gas barrier is formed between the second air seal and the air inlet and outlet module 2.
The gas used by the second sealing air tap 52 and the third sealing air tap 53 is provided by a second gas supply unit 55, the input end of the second gas supply unit 55 is connected with the gas exhaust part of the gas inlet and exhaust module 2, and the output end is connected with the second sealing air tap 52 and the third sealing air tap 53.
It should be understood that the gas emitted from the second sealing nozzle 52 and the third sealing nozzle 53 does not enter the combustion zone 13 for combustion, and thus the gas subjected to the combustion process should be used.
Referring to fig. 3, as a specific embodiment of the rotary thermal oxidation system provided by the application, the first sealing air tap 51 is composed of a main body 511 and an air channel 512 located in the main body 511, a first end of the air channel 512 is located in the main body 1, and a second end of the air channel 512 is located outside the main body 1.
In the direction of the flow velocity of the gas in the gas passage 512, the flow area of the gas passage 512 tends to increase, that is, the coverage of the gas ejected from the first sealing gas nozzles 51 tends to increase, which helps to reduce the empty area between the adjacent first sealing gas nozzles 51.
The structures of the second sealing air tap 52 and the third sealing air tap 53 are the same as those of the first sealing air tap 51, and will not be described here again.
Further, the two sides of the first sealing air tap 51 are abutted against the adjacent first sealing air tap 51, that is, for the first sealing air tap 51 distributed on the main body 1, the first sealing air tap 51 forms a physical seal first, and then forms a gas barrier by means of the sprayed gas.
Further, the two sides of the second sealing air tap 52 are abutted against the adjacent second sealing air tap 52, that is, for the second sealing air tap 52 distributed on the main body 1, the second sealing air tap 52 forms a physical seal first, and then forms a gas barrier by means of the sprayed gas.
Further, the two sides of the third sealing air tap 53 are abutted against the adjacent third sealing air tap 53, that is, for the third sealing air tap 53 distributed on the main body 1, the third sealing air tap 53 forms a physical seal first, and then forms a gas barrier by means of the sprayed gas.
As a specific embodiment of the rotary regenerative thermal oxidation system provided in the application, the air injection end of the first sealing air tap 51 is inclined towards the direction close to the combustion area 13, so that the air injected by the first sealing air tap 51 can enter the combustion area 13 for combustion, and the full utilization of the air is realized.
As an embodiment of the rotary regenerative thermal oxidizer system provided herein, the air injection end of the second sealing air cap 52 is inclined in a direction away from the combustion zone 13. At this time, the gas ejected from the second sealing nozzle 52 does not affect the gas barrier formed by the first sealing nozzle 51.
As a specific embodiment of the rotary heat storage oxidation system provided in the application, the air injection end of the third sealing air tap 53 is inclined towards the direction close to the combustion area 13, so as to form a third gas seal, and intercept the gas possibly escaping between the air inlet and outlet module 2 and the heat exchange module 3.
It should be understood that, as the gas between the air inlet and outlet module 2 and the heat exchange module 3 escapes, the air pressure between the second air seal and the third air seal gradually increases, and when the air pressure is leveled, the gas between the air inlet and outlet module 2 and the heat exchange module 3 cannot escape.
Referring to fig. 1, the gas ejected from the second sealing nozzle 52 and the third sealing nozzle 53 is discharged from the main body 1 through a pipe and then fed into the exhaust pipe 24.
The embodiments of the present application are all preferred embodiments of the present application, and are not limited in scope by the present application, so that all equivalent changes according to the structure, shape and principle of the present application are covered by the scope of the present application.
