[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] See also Figure 1-4As shown, a three-way catalytic purification device for moxa smoke comprises a catalytic purification device 6, an air duct 5, a heat dissipation pipe 3, a purification box 2 and an induced draft fan 1 connected in sequence, the catalytic purification device 6 comprises a purification cylinder 15, the interior of the purification cylinder 15 is fixedly provided with a combustion cylinder 12 and a three-way catalytic converter 16 in sequence along its axial direction, an electric heating core 13 is fixedly connected to the inner side of the combustion cylinder 12, a heat preservation layer 14 is provided between the combustion cylinder 12 and the purification cylinder 15, and a first air intake pipe 7 is fixedly connected to the outer side of one end of the purification cylinder 15 corresponding to the combustion cylinder 12;

[0034] The purification box 2 includes a box body 11, and the air inlet and air outlet of the box body 11 are connected to the limit frame 20 through an elastic telescopic tube 21. A plurality of exhaust gas filter modules 25 are clamped and fixed between the two limit frames 20, and a sealing frame 18 is fixedly connected to the edge of the exhaust gas filter module 25 at a position corresponding to the limit frame 20.

[0035] Start the induced draft fan 1, and the moxa smoke enters the catalytic purification device 6 through the first air intake pipe 7. The components that are not completely burned are fully burned under the heating of the electric heating core 13. Then the exhaust gas passes through the three-way catalytic converter 16 at high temperature, and the harmful gas components are oxidized, reduced and decomposed into harmless carbon dioxide, water and nitrogen. The exhaust gas enters the heat dissipation pipe 3 through the air duct 5, and enters the purification box 2 after being cooled by the heat dissipation pipe 3. The exhaust gas is filtered and purified by the exhaust gas filter module 25 in the purification box 2 so that the exhaust gas meets the emission standards.

[0036] By arranging a thermal insulation layer 14 on the outside of the combustion tube 12, the heat loss of the electric heating core 13 can be reduced, thereby reducing energy consumption; under the action of the elastic elastic tube 21 itself, the limit frame 20 is pushed to clamp and fix the exhaust gas filter module 25, thereby making it easier to disassemble, assemble and replace the exhaust gas filter module 25.

[0044] The high-temperature exhaust gas treated by the catalytic purification device 6 exchanges heat with the untreated moxa smoke under the action of the heat exchange plate 24, increasing the initial temperature of the moxa smoke, thereby reducing energy consumption. Preferably, the high-temperature exhaust gas and the untreated moxa smoke flow in opposite directions when passing through the air duct 5.
