Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0036] To facilitate understanding of this embodiment, the following is a brief introduction to the technologies involved in this application.

[0037] Pulsed plasma refers to a highly ionized, overall neutral gaseous substance composed of free electrons, free ions, free radicals, and central particles produced when atoms and atomic groups in the gas are deprived of some electrons and ionized under the action of high-voltage narrow pulses.

[0038] The generation of plasma mainly relies on the continuous collision reaction of species inside the plasma, and also on the acceleration of electrons in the electric field to obtain extremely high kinetic energy, so as to transfer energy through collision and dissociate gas molecules.

[0039] After introducing the technical terms involved in this application, the application scenarios and design concepts of the embodiments of this application are briefly introduced.

[0040] Pulse plasma deodorization technology and oxidation spray technology are two common deodorization technologies. Ordinary water spray technology has low deodorization efficiency, while pulse plasma deodorization technology has high deodorization efficiency, but the treated gas will contain some residual oxidative free radicals and small molecular odor components that have not fully reacted, resulting in incomplete deodorization and unsatisfactory results.

[0041] Based on this, an embodiment of the present application provides an integrated deodorization device and system.

[0042] Example 1

[0043] The present application provides an integrated deodorizing device, combined with Figure 1 As shown, the device includes: a device body 1, a pulse plasma deodorization mechanism 2 and a spray deodorization mechanism 3.

[0044] An air inlet 11 is provided at the bottom of the device body 1 , and an air outlet 12 is provided at the top.

[0045] The pulse plasma deodorization mechanism 2 is disposed above the air inlet 11 of the device body 1 and is used for deodorizing the gas entering the device body 1 .

[0046] The spray deodorization mechanism 3 is arranged above the pulse plasma deodorization mechanism 2, and is used for re-deodorizing the gas after the deodorization treatment by the pulse plasma deodorization mechanism.

[0047] The integrated deodorization device provided in the present application integrates a pulse plasma deodorization mechanism 2 and a spray deodorization mechanism 3. The pulse plasma deodorization mechanism 2 performs a first deodorization treatment on the body 1 entering the device, and then performs a second deodorization treatment through the spray deodorization mechanism 3. The unreacted oxidative free radicals and small molecular odors generated by the first deodorization treatment can be further oxidized and decomposed to improve the odor treatment effect and efficiency.

[0048] The air inlet 11 is connected to the output end of the fan 10 , and the fan 10 is used to extract external odor and output it to the device body 1 from the output end.

[0049] In combination with the first aspect, the pulse plasma deodorization mechanism 2 includes: a pulse plasma module 21 and a narrow pulse power supply 22 .

[0050] The pulse plasma module 21 is disposed above the air inlet 11 in the device body 1 .

[0051] The narrow pulse power supply 22 is disposed outside the device body 1 and is electrically connected to the pulse plasma module 21 .

[0052] The narrow pulse power supply 22 provides energy for the pulse plasma module 21, and a strong pulse plasma reaction area is formed in the area where the pulse plasma deodorization mechanism 2 is located. Under the action of the strong electric field, high-energy electrons are generated in the reaction area. The high-energy electrons bombard 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 odor molecules, causing them to undergo chain dissociation and lose their odor characteristics. In this way, after being processed by the pulse plasma deodorization mechanism 2, the gas entering the device body 1 becomes odorless molecules, remaining unreacted oxidative free radicals and incompletely reacted small molecular odors.

[0053] In combination with the first aspect, the spray deodorization mechanism 3 includes a spray pipe 31 and a spray head 32. The spray pipe 31 is arranged above the pulse plasma deodorization mechanism 2. Figure 2 As shown, a spray head 32 is connected to the spray pipe 31, and an input end of the spray pipe 31 is connected to a spray liquid source.

[0054] The input end of the spray pipe 31 is connected to the spray liquid source, so that the spray liquid enters the spray pipe 31 and is sprayed out by the nozzle 32. The spray liquid contacts the gas that has been treated for the first time and runs upward, so as to absorb the unreacted oxidative free radicals in the first deodorization treatment, thereby improving the oxidizing property of the spray liquid, and further oxidizing and decomposing the unreacted small molecular odor in the first deodorization treatment. In this way, the deodorization efficiency and deodorization effect are improved through two deodorization treatments.

[0055] In combination with the first aspect, the device further comprises a packing layer 4. The packing layer 4 is arranged between the pulse plasma deodorization mechanism 2 and the spray deodorization mechanism 3, and the packing layer 4 is filled with packing 41, and there are gaps between adjacent packings 41 for gas flow.

[0056] It can be understood that the packing layer 4 is filled with a packing 41, which serves as a contact medium between the gas phase and the liquid phase. The gas enters the device body 1 through the air inlet 11 and undergoes the first deodorization treatment, and then it countercurrents with the liquid phase and needs to continue to move through the gaps between adjacent packings 41. In this process, the gas phase and the liquid phase are in close contact on the surface of the packing 41 for mass transfer, which can increase the contact area and contact time of the gas phase and the liquid phase, and is conducive to a full reaction.

[0057] In combination with the first aspect, the filler 41 is a sphere.

[0058] The outer edge of the sphere is arc-shaped, and two adjacent spherical fillers 41 can increase the contact area and duration of the gas phase and the liquid phase without affecting the gas movement and liquid flow.

[0059] In combination with the first aspect, the device further includes:

[0060] The cyclone 5 is arranged below the spray deodorization mechanism 3 and is used to divert the spray liquid in the upper layer;

[0061] The collecting tank 6 is arranged on the inner wall of the device body 1 and is located below the cyclone 5 . The opening of the collecting tank 6 faces upward and is used to collect the spray liquid diverted by the cyclone 5 .

[0062] The cyclone 5 diverts the spray liquid to prevent the spray liquid from dripping into the pulse plasma module 21, and the diverted spray liquid flows into the collecting tank 6 to recover the spray liquid.

[0063] In combination with the first aspect, the collecting tank 6 is communicated with a liquid storage tank 7 disposed outside the device body 1 , and is used to direct the collected spray liquid to the liquid storage tank 7 .

[0064] In this way, the recovered spray liquid flows into the liquid storage tank 7 for unified recovery. At the same time, it can also prevent excessive overflow of the spray liquid in the collection tank 6 from dripping onto the pulse plasma module 21 below, which is beneficial to improving the service life of the equipment.

[0065] In the present application, the spray liquid is water.

[0066] In combination with the first aspect, the liquid storage tank 7 is connected to the input end pipeline of the spray pipe 31; and a booster pump 8 is arranged on the pipeline.

[0067] In this way, the spray liquid in the liquid storage tank 7 is re-input into the spray pipe 31 to realize the recycling of the spray liquid, which can reduce the resources required for deodorization and reduce the cost of equipment use and odor treatment.

[0068] The booster pump 8 is turned on to pressurize the liquid flow in the pipeline, so as to quickly transport the liquid in the liquid storage tank 7 to the spray pipe 31 to improve efficiency.

[0069] In combination with the first aspect, the device further includes: a defogger mechanism 9.

[0070] The demisting mechanism 9 is arranged above the spray deodorizing mechanism 3, and is used to perform demisting treatment on the gas that has been deodorized again by the spray deodorizing mechanism. In this way, the deodorized gas is discharged from the air outlet 12 on the device body 1 after being demisted.

[0071] As an implementable manner, the demisting mechanism 9 is an activated carbon layer filled with activated carbon particles. After the demisting effect of the activated carbon, the odorless gas continues to move upward and is discharged from the air outlet 12 to the external environment.

[0072] The integrated deodorization device provided in this application combines pulse plasma deodorization technology and oxidation spray deodorization technology to improve the treatment effect of malodorous gas. The actual application process is as follows:

[0073] First, the odor is collected by the fan 10 and sent into the device body 1.

[0074] After that, the odor passes through the high-energy pulse plasma module 21 from bottom to top. The pulse plasma module 21 is provided with energy by the narrow pulse power supply 22, forming a strong pulse plasma reaction area in this area. Under the action of the strong electric field, high-energy electrons are generated in the reaction area. The high-energy electrons bombard 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 odor molecules, causing them to undergo chain dissociation and lose their odor characteristics. After this deodorization treatment, the gas components become odorless molecules, remaining unreacted oxidative free radicals and incompletely reacted small molecular odors.

[0075] The odor passes through the cyclone 5 and the collecting tank 6, and the upper layer of the oxidizing spray liquid is diverted and collected to prevent the spray liquid from dripping into the pulse plasma module 21. The collected oxidizing spray liquid enters the circulating water tank for storage and is sent to the spray deodorization mechanism 3 for spraying by the booster pump 8, and the cycle is repeated.

[0076] Finally, the gas passes through the demisting mechanism 9, removes the water mist, and is discharged into the external environment through the air outlet 12.

[0077] In a second aspect, the present application provides an integrated deodorization system, which includes the integrated deodorization device as described above.
