[0002] The regenerative catalytic incinerator is an advanced organic waste gas treatment equipment. It combines low-temperature catalytic oxidation with heat storage technology. It is used to treat various places and industries that produce organic waste gas. The regenerative catalytic incinerator uses a special ceramic heat storage body to recover and reuse heat energy. When the exhaust gas passes through the heat storage body, the exhaust gas is preheated to a temperature close to the thermal oxidation temperature, and the ceramic body heats up by absorbing the heat energy in the exhaust gas. Subsequently, the preheated exhaust gas enters the combustion chamber for catalytic oxidation. Under the action of a specific catalyst, the organic matter is oxidized and decomposed at a lower temperature to generate CO2 and H2O, and release a large amount of heat energy. The catalyst reduces the activation energy required for the reaction, thereby accelerating the oxidation reaction;

[0029] Embodiment 1, in order to solve the problem that the existing regenerative catalytic incinerator has poor heat recovery effect on the heat energy generated by its use, resulting in low utilization rate of the furnace body 1, discloses:

[0030] The furnace body 1 has a mounting seat 2 sealed on the top, and an air supply pipe 3 is sealed and installed in the internal groove of the mounting seat 2, and the outer end of the air supply pipe 3 extends through and extends to the outside of the mounting seat 2;

[0031] It also includes: a mounting seat 2, the top ends of which are respectively grooved and sealed to penetrate and install a first feed pipe 5 and a second feed pipe 6, and the first feed pipe 5 and the second feed pipe 6 are symmetrically arranged about the vertical center line of the mounting seat 2, and the bottoms of the first feed pipe 5 and the second feed pipe 6 extend through and extend to both sides of the top of the furnace body 1, the furnace body 1, the internal grooves of which are connected with a main heat exchange pipe 9, and the main heat exchange pipe 9 is spiral, and the main heat exchange pipe 9 and the furnace body 1 are fitted, and a catalyst chamber 10 is arranged inside the furnace body 1.

[0033] like Figure 1-Figure 2 As shown, when the furnace body 1 incinerates domestic waste and generates a large amount of high-temperature exhaust gas, the external water source is transported to the main heat exchange pipe 9 through the water inlet pipe 7. The heat generated by the furnace body 1 can be recovered through the main heat exchange pipe 9 to avoid the waste of heat energy generated and improve the utilization rate of the furnace body 1.

[0034] Embodiment 2 is different from Embodiment 1 in that the catalyst required for the furnace body 1 can be fed intermittently and quantitatively to avoid the phenomenon of material waste caused by excessive catalyst feeding, and discloses:

[0035] The mounting base 2 has a driving motor 4 screwed on its top, and the output end of the driving motor 4 is connected to a rotating shaft 16, and the outer side of the rotating shaft 16 is penetrated and connected with a second half gear 15. The furnace body 1 has a moving base 13 slidably mounted on the top slot, and two rows of tooth blocks 14 are arranged on the front and rear sides of the interior of the moving base 13, and the two rows of tooth blocks 14 are arranged at equal intervals, and the inner sides of the two rows of tooth blocks 14 are meshed and connected with the second half gear 15.
