AI Technical Summary
Traditional heating devices suffer from problems such as ammonia and nitrogen pollution, low heat conversion rate, difficulty in control, and poor safety. Furthermore, microwave heating is harmful to the human body and is not suitable for ductwork spaces.
The system employs an electric heating method using honeycomb thermal storage conductors and thermally conductive resistors. The heat generated by the resistors is absorbed by the honeycomb thermal storage conductors and combined with a heat exchanger for preheating and combustion of exhaust gas. High-temperature combustion is achieved through the efficient electric heating of the thermally conductive resistors.
It achieves efficient and safe exhaust gas combustion, with temperatures reaching 800℃-1000℃, no ammonia or nitrogen emissions, rapid heating, safety and reliability, and is suitable for pipeline spaces with a wide range of applications.

[0015] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0016] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.
[0017] A waste gas combustion device, reference Figure 1 , including a hollow shell 1. The shell 1 is made of a heat-insulating material, such as a heat-insulating board, a foam board, etc. An exhaust gas inlet 2 and an exhaust gas outlet 3 are provided at the lower end of the shell 1. Two heat exchangers 6 and a ceramic heat storage component are sequentially arranged inside the shell 1 from top to bottom. For those skilled in the art, the number of heat exchangers 6 can be one, three, four, etc., and can be set according to actual conditions.
[0018] The heat exchanger 6 is provided with a first inlet connected to the exhaust gas inlet 2, a first outlet connected to the air inlet of the honeycomb heat storage conductor assembly, a second inlet connected to the air outlet of the honeycomb heat storage conductor assembly, and a second outlet connected to the exhaust gas outlet 3. The first inlet is connected to the first outlet, and the second inlet is connected to the second outlet.
[0019] The ceramic heat storage component includes a plurality of heat-generating media 5 and a plurality of honeycomb heat storage conductors 4. The heat-generating media 5 are thermally conductive resistors. The plurality of heat-generating media 5 are evenly distributed from top to bottom. Figure 2, and is arranged in a winding manner to form a plurality of placement openings 7. The cross-sectional dimensions of the placement openings 7 match the cross-sectional dimensions of the honeycomb heat storage conductor 4. A plurality of honeycomb heat storage conductors 4 are installed at the placement openings 7, and the outer wall of the honeycomb heat storage conductor 4 is closely fitted with the heat-generating medium 5. The heat-generating medium 5 is arranged through the housing 1.
[0020] When the exhaust gas needs to be burned, the heating medium 5 is electrically conductive to achieve resistance heating, and the honeycomb heat storage conductor 4 absorbs the heat generated by the resistance. The exhaust gas enters the shell from the exhaust gas inlet 2, and exchanges heat with the exhaust gas after combustion in the heat exchanger 6 to complete preheating. After preheating, it enters the honeycomb heat storage conductor assembly for heating and combustion. The exhaust gas after combustion is discharged from the exhaust gas outlet 3 through the heat exchanger 6. When the exhaust gas after combustion passes through the heat exchanger 6, the unburned exhaust gas is preheated to reduce heat loss, thereby maximizing the use of the heating medium to generate heat.
