Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0038] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0039] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0040] Embodiment 1:

[0041] like Figure 1 As shown, an embodiment of the present application provides an electromagnetic heating catalytic combustion device, including a heat exchanger 1, a catalytic burner 2, and also includes: an electromagnetic heater 3, which is fixedly connected between the heat exchanger 1 and the catalytic burner 2 through a transport pipe; an electromagnetic heating coil 301, which is arranged in the electromagnetic heater 3; wherein the electromagnetic heating coil 301 is wound with a high temperature and high pressure resistant cable; and also includes an intelligent temperature control meter 302, which is fixedly connected to the electromagnetic heater 3 and is used to control the heating temperature.

[0042] Furthermore, it also includes a cold end inlet 4, which is arranged at the front end of the heat exchanger 1; a first air outlet 5, which is arranged at the rear end of the heat exchanger 1 and connected to the electromagnetic heater 3 through a transport pipe; a fan 6, which is fixedly connected to the cold end inlet 4 through a transport pipe; a hot end inlet 7, which is arranged at the upper end of the heat exchanger 1 and connected to the catalytic burner 2 through a transport pipe; a second air outlet 8, which is arranged at the upper end of the heat exchanger 1, located on one side of the hot end inlet 7.

[0043] Furthermore, the catalytic burner 2 includes a catalytic chamber 201; an inlet flame arrester 202, which is arranged at the connection end between the catalytic chamber 201 and the electromagnetic heater 3; an outlet flame arrester 203, which is arranged at the connection end between the catalytic chamber 201 and the hot end inlet 7; a safety valve 204, which is arranged at the upper end of the catalytic chamber 201; and a catalyst 205, which is arranged inside the catalytic chamber 201.

[0044] Furthermore, it also includes a temperature sensor 9 which is arranged on the catalyst chamber 201 ; and a PLC controller 10 which is fixedly connected to the catalyst chamber 201 .

[0045] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the exhaust gas needs to be catalytically burned, the exhaust gas first enters the cold end inlet 4 of the heat exchanger 1 under the action of the fan 6, and the heat exchanger 1 can increase the exhaust gas temperature to 200°C, and then the 200°C exhaust gas is discharged from the first air outlet 5 and enters the electromagnetic heater 3 through the transport pipe. Through the heating of the electromagnetic heating coil 301, the exhaust gas is automatically controlled to the set heating temperature of 350°C-420°C. The temperature setting is detected and adjusted by the intelligent temperature control meter 302. The heated exhaust gas enters the catalyst chamber 201 through the transport pipe. Under the action of the catalyst 205, the exhaust gas is catalytically oxidized and decomposed into carbon dioxide and oxygen. The gas at the outlet end of the catalyst chamber 201 is 420°C and reaches the hot end inlet 7 of the heat exchanger 1 through the transport pipe. This part of the heat source is recovered for exhaust gas preheating, and the 420°C hot air is cooled to 200°C through the exchanger, thereby achieving the effect of exhaust gas circulation and desorption.

[0046] Furthermore, electromagnetic heating can make the heat conversion efficiency as high as 98%, and adopts frequency conversion technology, which saves more than 30% energy compared with traditional electric heating and gas heating equipment, and the electromagnetic heating coil 301 is wound with special cables resistant to high temperature and high pressure, with good insulation, and the surface temperature is only about 60 degrees, which effectively prevents human body burns, and the practical life is more than 10 years, effectively reducing maintenance costs. The catalyst chamber 201 is provided with an inlet flame arrester 202, an outlet flame arrester 203, a safety valve 204 and a temperature sensor 9, which can further protect the catalyst chamber 201 and improve the overall safety.

[0048] In this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: an electric cooling valve 11, which is arranged on the transport pipe in the front section of the fan 6; wherein the electric cooling valve 11 is electrically connected to the PLC controller 10.

[0049] In this embodiment of the present application, due to the use of the above-mentioned structure, before shutdown, the electric cooling valve 11 can be opened to blow cold the catalytic combustion chamber 201 for 30 minutes to achieve the cooling effect on the catalytic combustion chamber 201, and the electric cooling valve 11 is electrically connected to the PLC controller 10, which is convenient for manual automatic adjustment and is more convenient and intelligent.
