[0023] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0024] like Figure 1-2 As shown, the present application provides an energy-saving and efficiency-improving device suitable for pulse plasma deodorization, comprising:

[0025] A device housing 1, wherein a plurality of functional areas for treating odor are arranged inside the device housing 1, and a heat exchange area 2 is arranged on the top of the functional areas;

[0026] The device housing 1 is an external housing of the functional area, which is used to surround and protect the functional area. It usually has heat insulating materials or heat-insulating materials to reduce heat loss.

[0027] A pulse power supply 3 is provided on one side outside the device housing 1 .

[0028] The model of the pulse power supply 3 is DLZ-52, the power supply output voltage is 0-35 kV, the output frequency is 2000-5000 Hz, and the pulse width is 1.5 μm; the power supply output parameters in the deodorization process are mainly adjusted by the conduction angle and the output frequency.

[0029] The functional area includes a filtration pretreatment area 4 , a high-energy plasma area 5 and an adsorption reaction area 6 . The high-energy plasma area 5 is arranged on the top of the filtration pretreatment area 4 , and the adsorption reaction area 6 is arranged on the top of the high-energy plasma area 5 .

[0030] The pulse power supply 3 is arranged on one side of the high-energy plasma zone 5 .

[0031] Hot air circulation ducts 8 and cold air circulation ducts 9 are respectively provided on both sides of the device shell 1. The high-energy plasma zone 5 and the heat exchange zone 2 are connected through the hot air circulation duct 8, and the high-energy plasma zone 5 and the heat exchange zone 2 are also connected through the cold air circulation duct 9.

[0032] The adsorption reaction zone 6 is also filled with activated carbon 12 .

[0033] like Figure 4 As shown, the filtering pretreatment area 4 is provided with a filter mesh 13 and filter cotton 14 , and the filter cotton 14 is arranged between two filter meshes 13 .

[0034] The filtering pretreatment zone 4 filters the fine mist droplets in the odor, which may carry odorous substances, and adsorbs the residual substances in the reaction.

[0035] An air inlet 15 is disposed on one side of the filtration pretreatment zone 4 , and the air inlet 15 is communicated with the filtration pretreatment zone 4 .

[0036] An exhaust port 16 is also provided at the top of the heat exchange area 2 .

[0037] like Figure 2 As shown, when the pulse power supply 3 is running continuously, the general temperature can reach 70°C, and a large amount of heat will be emitted. Generally, air is used to cool it, and the cold air is sucked into the high-energy plasma zone 5 from the cold air circulation duct 9 through the axial flow fan. After flowing through the pulse power supply 3, a large amount of heat is taken away, and the cold air becomes hot air. The hot air enters the heat exchange zone 2 from the hot air circulation duct 8 by the axial flow fan.

[0038] In the heat exchange zone 2 , the exhaust gas temperature increases, the ozone in the gas is accelerated to decompose, the hot air temperature decreases, and is sent into the high-energy plasma zone 5 by the axial flow fan to cool the pulse power supply 3 .

[0039] The odor enters the filtration pretreatment zone 4 from the air inlet 15, and the fine droplets in the odor, which carry odorous substances, are removed. After the residual substances in the adsorption reaction, it enters the high-energy plasma zone 5. The pulse power supply 3 discharges the high-energy plasma zone 5. The high-energy plasma zone 5 bombards water molecules, oxygen molecules and other substances in the odor to produce a large number of free radicals. These free radicals can produce redox reactions with odor characteristic substances. High-energy electrons can also directly act on the odor molecules, causing them to undergo chain dissociation and lose their odor characteristics, thereby obtaining treated gas. The treated gas is adsorbed or filtered by the activated carbon 12 in the adsorption reaction zone 6, and a small amount of remaining odor droplets and odor are captured to prevent the odor molecules from escaping after the odor droplets are gasified, thereby achieving a good deodorization purpose.

[0040] The heat generated by the pulse power supply 3 is directed to the heat exchange area 2 through the axial flow fan to heat the gas. After the temperature is increased, the decomposition rate of ozone can be effectively increased, which is beneficial to the waste heat to achieve energy saving effect and accelerate the decomposition of ozone to increase the deodorization efficiency.

[0041] like Figure 3 As shown, an air circulation duct 10 and a plate 11 are arranged in the high-energy plasma zone 5, and the air circulation duct 10 and the plate 11 are arranged vertically.

[0042] Hot air flows from the hot air circulation duct 8 into the air circulation duct 10 to heat the odor in the heat exchange area 2, and flows back to the high-energy plasma area 5 from the cold air circulation duct 9 to serve as the pulse power supply 3. The odor flows freely between the plates 11 and 11. When the treated odor meets the emission standards, it is discharged from the exhaust port 15.

[0043] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
