Referring to fig. 1 to 4, the present application provides a deodorizing device 100, which can be applied to a kitchen garbage disposer. The kitchen garbage disposer can crush, heat and decompose and ferment kitchen garbage to generate fertilizer, and the deodorizing device 100 can purify tail gas generated by garbage disposal of the kitchen garbage disposer to eliminate peculiar smell.

Referring to fig. 1 to 3, the deodorizing device 100 includes an airflow channel through which the exhaust gas flows, so as to purify and deodorize the exhaust gas during the exhaust gas flowing through the airflow channel. Wherein the deodorizing device 100 comprises an ozone generator 7 and an ozone catalyst 9. The ozone generator 7 has an ozone generating electrode 71, and the ozone generating electrode 71 is disposed on a flow path of the exhaust gas in the gas flow path to ionize oxygen in the exhaust gas to generate ozone. The ozone catalyst 9 is disposed in the airflow passage downstream of the ozone generating electrode 71. Wherein the exhaust gas flowing through the ozone generating electrode 71 to generate ozone flows to the ozone catalyst 9 to perform an ozone catalytic oxidation reaction to purify and remove odor.

In this embodiment, the air flow channel is formed by splicing a plurality of pipelines. Specifically, the deodorizing device 100 includes an air inlet pipe 1, a catalytic reaction pipe 2, an activated carbon filling pipe 3, a first connecting pipe 4, a second connecting pipe 5, and an air outlet pipe 6. The air inlet pipe 1, the catalytic reaction pipe 2, the activated carbon filling pipe 3, the first connecting pipe 4, the second connecting pipe 5 and the exhaust pipe 6 are communicated, and the air flow channel is formed in the air inlet pipe. The ozone generator 7 is connected to the air inlet pipe 1. The mouth of the exhaust pipe 6 is connected with an air draft device 8 to draft air flow in the air flow channel.

Referring to fig. 1 to 3, a mounting plate 11 is formed on the air inlet pipe 1, and the ozone generator 7 is fixed on the mounting plate 11. An electrode mounting opening 101 is formed in the air inlet pipe 1, a base 72 of the ozone generator 7 is located outside the air inlet pipe 1, and the electrode mounting opening 101 is shielded by the ozone generating electrode 71. In an embodiment, the ozone generator 7 is a ceramic-plate ozone generator, that is, the ozone generating electrode 71 is a ceramic-plate electrode, and is disposed near the electrode mounting opening 101, and the tail gas in the air flow channel is ionized by the ceramic-plate electrode to form ozone and flows continuously. In this embodiment, the substrate 72 of the ozone generator 7 is disposed outside the air inlet pipe 1, which is convenient for installation and is not easy to pollute and damage; the shielding of the electrode mounting port 101 by the ozone generating electrode 71 prevents the reduction of the exhaust gas suction efficiency caused by the suction of outside air from the electrode mounting port 101. In other embodiments, the ozone generating electrode 71 may also extend into the air inlet pipe 1 and avoid air intake by providing a sealing structure between the air inlet pipe 1 and the base 72. In other embodiments, the ozone generator 7 may also employ other types of ozone generating devices.

Oxygen in the exhaust gas flowing through the electrode mounting port 101 is ionized by the ozone generating electrode 71 to generate ozone, and the exhaust gas mixed with ozone flows to the catalytic reaction tube 2 through the first connection tube 4. The air inlet pipe 1 and the catalytic reaction pipe 2 are connected through the first connecting pipe 4, and the first connecting pipe 4 is an elbow. The bent pipe can be bent in an L shape, a U shape or an S shape. The first connecting pipe 4 is arranged in a bent pipe, can play a certain role in blocking airflow, and can enable ozone and tail gas to be mixed and reacted to a certain degree before entering the catalytic reaction pipe 2 to perform ozone catalytic reaction, so that ozone and tail gas are mixed for primary sterilization, disinfection and deodorization.

Referring to fig. 3, the cross-sectional area of the catalytic reaction tube 2 is larger than that of the first connecting tube 4, so that the exhaust gas mixed with ozone can permeate the catalytic reaction tube 2 to facilitate the ozone catalytic oxidation reaction. The ozone catalyst 9 is disposed in the catalytic reaction tube 2. Specifically, a heating element 23 and a carrier 24 are disposed in the catalytic reaction tube 2, the heating element 23 is configured to heat the internal space of the catalytic reaction tube 2, and the carrier 24 is configured to carry the ozone catalyst 9. The carrier 24 is located downstream of the heating element 23, and the ozone catalyst 9 is placed on the carrier 24 also downstream of the heating element 23. In this way, the exhaust gas flows through the heating element 23 to be heated and then flows to the ozone catalytic converter 9, which is more favorable for the ozone catalytic oxidation reaction. In this embodiment, the heating element 23 is a heating tube; in other embodiments, the heating element 23 may be a heating wire, a heating sheet, or the like. The carrier 24 is a partition plate provided with a plurality of meshes, and the partition plate is fixed on the inner wall surface of the catalytic reaction tube 2. The carrier 24 is provided with a partition board with meshes, which can allow air flow to pass through and is beneficial to uniformly distributing the ozone catalyst 9 on the carrier 24 so as to improve the reaction efficiency. In other embodiments, the carrier 24 may be configured as a hook, a support rod, or other structures, so long as the carrier can carry the ozone catalyst 9. The ozone catalyst 9 may be a metal oxide catalyst such as titanium dioxide, aluminum oxide, manganese dioxide, etc., or a metal catalyst such as titanium, copper, zinc, iron, nickel, manganese, etc.

The lower end of the catalytic reaction tube 2 is connected to the first connection tube 4 through a first bottom cover 21. The upper end of the catalytic reaction tube 2 is connected to the second connection tube 5 through the first upper cover 22, so as to discharge the gas after the catalytic reaction out of the catalytic reaction tube 2 for the next process. The catalytic reaction tube 2 has a discharge port for discharging exhaust gas out of the catalytic reaction tube 2, the area of the discharge port is smaller than the cross-sectional area of the catalytic reaction tube 2, and a baffle 221 provided with a plurality of meshes is disposed at the discharge port. In this embodiment, the middle area of the first upper cover 22 forms the baffle plate 221 with a plurality of meshes, and the air flow in the catalytic reaction tube 2 enters the second connecting tube 5 through the meshes on the baffle plate 221. The area of the exhaust port is smaller than the cross-sectional area of the catalytic reaction tube 2, and the baffle 221 is arranged at the exhaust port, so that a certain blocking effect can be achieved on the air flow, and the exhaust gas can be fully reacted in the catalytic reaction tube 2. The baffle 221 with meshes can also play a role in filtering, so that dust and the like can be reduced from entering the activated carbon filling pipe 3 through the second connecting pipe 5, and the replacement frequency of the activated carbon can be reduced.

The gas flow passing through the second connection pipe 5 enters the activated carbon filling pipe 3 disposed downstream of the catalytic reaction pipe 2 to be further purified by the activated carbon filled in the activated carbon filling pipe 3. The second connecting pipe 5 is an elbow pipe, and the elbow pipe can be bent in an L shape, a U shape or an S shape. In this embodiment, the shape of the activated carbon filling pipe 3 is substantially the same as that of the catalytic reaction pipe 2, the upper end of the activated carbon filling pipe 3 is provided with a second upper cover 21, the lower end is provided with a second bottom cover 32, and the middle areas of the second upper cover 21 and the second bottom cover 32 are provided with meshes, so that the filtering effect can be achieved. Because the air flow entering the activated carbon filling pipe 3 is subjected to primary purification and ozone catalytic oxidation and secondary purification in the mixing stage of ozone and tail gas, the air entering the activated carbon filling pipe 3 is relatively clean, and the replacement frequency of the activated carbon is reduced. The activated carbon particles in the activated carbon filling pipe 3 further perform purification treatment such as adsorption and oxidation of the gas, and are oxidized into carbon dioxide and steam, and then discharged through the exhaust pipe 6. One end of the exhaust pipe 6 is connected to the second bottom cover 32, and the other end is communicated with the exhaust device 8.
