[0002] In the field of catalytic combustion of waste gas, traditional gas-to-gas heat exchangers have low heat exchange efficiency, usually only between 40% and 60%. This results in a large amount of energy being consumed during the catalytic combustion process to maintain the ignition temperature of the catalyst, which increases operating costs and is not conducive to energy conservation and environmental protection.

A partition is vertically arranged inside the furnace body, dividing the furnace body into a first chamber and a second chamber. A communication port is provided on the partition. The first chamber contains, from top to bottom, a first regenerator chamber, a first catalytic chamber, a heating chamber, a second catalytic chamber, and a second regenerator chamber, which are connected in sequence. The second chamber contains a third regenerator chamber. A heating device is provided in the heating chamber. A switching mechanism is provided on the furnace body. The switching mechanism is used to switch the flow path of the waste gas, so that the waste gas first flows through the first regenerator chamber to release heat, then flows through the first regenerator chamber to absorb heat and the second regenerator chamber to release heat, and finally flows through the second regenerator chamber to absorb heat and the third regenerator chamber to release heat before being discharged.
[0005] Preferably, the switching mechanism includes a first switching valve, a second switching valve, a third switching valve, and a fourth switching valve. The first switching valve is located on one side of the heating chamber, the second switching valve is located at the top of the first heat storage chamber, the third switching valve is located at the bottom of the second heat storage chamber, and the fourth switching valve is located at the bottom of the second chamber.

[0008] In summary, this application includes the following beneficial technical effects: This utility model provides an energy-saving catalytic combustion device that improves heat exchange efficiency compared to traditional gas-to-gas heat exchangers by repeatedly storing and releasing heat in the waste gas. The efficient heat recovery and utilization reduces the energy consumption of the heating device, achieving the goal of energy saving. The combination of multiple catalytic chambers and heat storage chambers ensures that the waste gas is fully decomposed at the catalyst ignition temperature, resulting in stable treatment efficiency. This achieves the effect of improving the heat exchange efficiency and energy saving of the catalytic combustion device. Attached Figure Description

[0013] This application discloses an energy-saving catalytic combustion device. (Refer to...) Figure 1 The energy-saving catalytic combustion device includes a furnace body 1. A partition 11 is vertically arranged inside the furnace body 1, dividing the furnace body 1 into a first chamber 12 and a second chamber 13. A connecting port 111 is provided on the partition 11. The first chamber 12 is arranged from top to bottom as a first heat storage chamber 121, a first catalytic chamber 122, a heating chamber 123, a second catalytic chamber 124, and a second heat storage chamber 125. The second chamber 13 is arranged as a third heat storage chamber 131. A heating device 2 is arranged in the heating chamber 123. The heating device 2 can be gas-fired or electric-fired. A switching mechanism is provided on the furnace body 1. The switching mechanism is used to switch the flow path of the exhaust gas, so that the exhaust gas first flows through the first heat storage chamber 121 to release heat, then flows through the first heat storage chamber 121 to absorb heat and the second heat storage chamber 125 to release heat, and finally flows through the second heat storage chamber 125 to absorb heat and the third heat storage chamber 131 to release heat before being discharged.
[0014] The switching mechanism includes a first switching valve 3, a second switching valve 4, a third switching valve 5, and a fourth switching valve 6. The first switching valve 3 is located on one side of the heating chamber 123, the second switching valve 4 is located at the top of the first heat storage chamber 121, the third switching valve 5 is located at the bottom of the second heat storage chamber 125, and the fourth switching valve 6 is located at the bottom of the second chamber 13.
[0015] Catalyst layers are provided in the first catalytic chamber 122 and the second catalytic chamber 124.
[0016] The first heat storage chamber 121, the second heat storage chamber 125 and the third heat storage chamber 131 are equipped with heat storage structures.
[0017] The implementation principle of an energy-saving catalytic combustion device according to an embodiment of this application is as follows: In the initial state, the first switching valve 3, the second switching valve 4, the third switching valve 5 and the fourth switching valve 6 are all closed, and the device is heated to the preset temperature by the heating device 2; First cycle: Open the first switching valve 3 and the second switching valve 4 to let the exhaust gas into the heating chamber 123. The exhaust gas flows into the first catalytic chamber 122. After being degraded by the catalyst, the tail gas enters the first heat storage chamber 121, transfers energy to the internal heat storage structure, and then is discharged through the second switching valve 4. Second cycle: Open the second switching valve 4 and the third switching valve 5, close the first switching valve 3, and let the exhaust gas enter the first heat storage chamber 121. After absorbing the heat stored in the first cycle, it flows into the first catalytic chamber 122. If the heat is insufficient, the heating device 2 will supplement the heat so that the exhaust gas reaches the ignition temperature and is catalytically degraded. The degraded tail gas flows into the second catalytic chamber 124 for further catalytic treatment, and then enters the second heat storage chamber 125 to release heat. Then it is discharged through the third switching valve 5. Third cycle: Open the third switching valve 5 and the fourth switching valve 6, close the second switching valve 4, and let the exhaust gas enter the second heat storage chamber 125 to absorb heat. It is degraded in the heating chamber 123, and then flows into the third heat storage chamber 131 through the baffle 11 to release heat and is discharged through the fourth switching valve 6. At the same time, the exhaust gas remaining in the first heat storage chamber 121 in the second cycle flows through the heating chamber 123 due to the negative pressure and is degraded. It also passes through the third heat storage chamber 131 and is discharged through the fourth switching valve 6.
[0018] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
