Description

Technical Field

[0001] The utility model belongs to the technical field of purifiers, and in particular relates to a dual-medium low-temperature plasma combined high-efficiency ozone catalytic filler coordinated integrated machine. Background Art

[0002] The fermentation tanks in the workshop produce a lot of waste gas. Although after two-stage washing + two-stage water removal, there is still a certain odor. In order to avoid the odor disturbing the public and the health of employees, the waste gas needs to be treated. In the prior art, there are some devices for treating organic odorous waste gas with coupled dielectric barrier discharge plasma, such as the Chinese invention patent with application number 201210055932.7. Therefore, although the existing plasma equipment can meet the needs of waste gas deodorization, the dual-medium discharge plasma has high energy. Although it can thoroughly purify the air, remove odors, and kill bacteria and viruses, in order to ensure the treatment effect, the plasma discharge will be excessive, and excessive ozone will be produced, affecting the indoor environment, thereby affecting human health; and the existing deozonation methods generally have high-temperature cracking methods or decomposing ozone by a longer residence time, but this method has the defects of incomplete deozonation or taking a long time.

[0003] For example, the Chinese utility model patent with application number 202110048229.2 discloses an online real-time disinfection, sterilization and deodorization device for the exhaust of a hospital central suction system, which uses low-temperature plasma to kill bacteria, viruses and other microorganisms in the exhaust of a vacuum pump in real time online. The plasma is generated by dual-medium barrier discharge. The high-energy electrons not only kill microorganisms, but also crack and oxidize odor molecules, thereby completing the three-in-one treatment of exhaust sterilization, disinfection and deodorization; but its shortcomings are: the filling amount of the deozonation and elimination filler is insufficient, and at the same time, due to higher requirements for the treatment effect, the filler life is short, so the catalytic material is frequently replaced. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a dual-medium low-temperature plasma combined high-efficiency ozone catalytic filler coordinated integrated machine.

[0005] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0006] A dual-medium low-temperature plasma combined high-efficiency ozone catalytic filler coordinated integrated machine comprises a chassis, wherein the chassis is provided with an air inlet for air intake, an air distribution cylinder, a deozonation filler drawer for installing a deozonation filler and an air outlet for air outlet from right to left, a plasma generating disk for sterilization and deodorization is installed on the air distribution cylinder, a flushing port for flushing the outer side wall of the plasma generating disk is also provided on the chassis, and a drainage port for discharging waste water is provided at the bottom.

[0007] Preferably, the deozonating filler drawer comprises a drawer panel and a drawer bottom plate net for installing the deozonating filler, and the drawer panel is connected to the drawer bottom plate net.

[0008] Preferably, a deozonizing catalytic filler is installed in the deozonizing filler drawer, and the deozonizing catalytic filler is a coal-based carbon or ceramic-based filler.

[0009] Preferably, the air inlet is connected to the water remover through a first flexible connection.

[0010] Preferably, the air outlet is connected to the induced draft fan through a second flexible connection, and the outlet of the induced draft fan is connected to the chimney.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Since the surface of the plasma generating disk will be stained with dirt after working for a long time, the surface of the plasma generating disk is rinsed through the nozzle on the rinse port connected to the water pipe to ensure that the plasma generating disk is always in a clean state to avoid affecting the discharge effect. The rinsed water flows out from the drain port;

[0013] 2. Since the waste gas contains a lot of water vapor, it has a great impact on the subsequent equipment processing load. Therefore, a dehumidifier is added before deozonation to further remove liquid water in the waste gas and ensure the treatment effect of low-temperature plasma;

[0014] 3. The deozonation filler drawer is equipped with honeycomb deozonation filler. The deozonation catalytic filler is one of coal-based carbon, ceramic-based filler or honeycomb zeolite, which is used to decompose ozone. The air passes through the filler for filtration and deozonation. It has a long service life (0.5-1.5 years under working conditions), less filler, stable deozonation effect and short reaction time.

[0015] 4. The waste gas treatment of the fermentation tank is based on the treatment process of adding "dehydrator + dual-medium low-temperature plasma + catalytic oxidation reactor" as the core. The designed waste gas treatment air volume is 30,000m 3 / h, the waste gas is transported to the chimney through the induced draft fan for discharge after being treated, which meets the emission standards, has good deodorization and ozone removal effects, and the plasma and ozone elimination catalyst are integrated into one device, which occupies a small area, has low resistance and is easy to install and construct.

DETAILED DESCRIPTION

[0022] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] like Figure 1-2 As shown, a dual-medium low-temperature plasma combined high-efficiency ozone catalytic filler coordinated integrated machine includes a chassis 1, and the chassis 1 is provided with an air inlet 3 for air intake, an air distribution cylinder 4, a deozonation filler drawer 11 for installing the deozonation filler and an air outlet 12 for air outlet from right to left, a plasma generating disk 7 for sterilization and deodorization is installed on the air distribution cylinder 4, and a flushing port 5 for flushing the outer wall of the plasma generating disk 7 is also provided on the chassis 1, and a drain port 10 for discharging waste water is provided at the bottom.

[0025] In this embodiment, after the exhaust gas enters the inner tank of the air distribution tube 4 and the middle area of ​​the plasma generator disk 7, it goes up or down respectively (the pretreated gas is evenly distributed through the gas distributor and enters the row plasma generator disk 7, so that the amount of gas passing through each plasma reaction tube is equal, and at the same time, the exhaust gas from different work sections is fully mixed to achieve the purpose of homogenization), and then enters the deozonizing filler on the deozonizing filler drawer 11, and then goes from top to bottom and from bottom to top respectively, and finally comes out from the air outlet 12.

[0026] Since the surface of the plasma generating disk 7 will be stained with dirt after working for a long time, the surface of the plasma generating disk 7 is rinsed through a nozzle connected to a water pipe on the rinse port 5 to ensure that the plasma generating disk 7 is always in a clean state to avoid affecting the discharge effect. The rinsed water flows out from the drain port 10.

[0027] Embodiment 2:

[0028] A dual-medium low-temperature plasma combined high-efficiency ozone catalytic filler coordinated integrated machine, which is different from Example 1 in that, Figure 1-2 As shown, the deozonating filler drawer 11 includes a drawer panel 15 and a drawer bottom plate net 14 for installing the deozonating filler, and the drawer panel 15 is connected to the drawer bottom plate net 14.

[0029] like Figure 1-2 As shown, the air inlet 3 is connected to the water eliminator 6 through the first flexible connection 2; the air outlet 12 is connected to the induced draft fan 13 through the second flexible connection 8, and the outlet of the induced draft fan 13 is connected to the chimney 9.

[0030] In this embodiment, the deozonation filler drawer 11 is equipped with a deozonation catalytic filler, which is one of coal-based carbon-based, ceramic-based filler or honeycomb zeolite. The multiphase ozone catalyst mainly uses a variety of high-efficiency metal oxides and metal elements as active catalytic materials, and uses honeycomb zeolite as a substrate to effectively increase the number and distribution uniformity of micropores, obtain a higher specific surface area, and maximize the ozone oxidation efficiency; in addition, honeycomb zeolite has good hydrophobicity and still has a high reaction efficiency under relatively high relative humidity.

[0031] The working principle of the utility model is:

[0032] Under the suction of the induced draft fan 13, the fermentation waste gas first undergoes the original two-stage washing and dewatering and demisting pretreatment, and then the waste gas passes through the dehydrator 6 to remove liquid water to ensure that the waste gas dust entering the plasma is effectively removed, and then enters the plasma combination high-efficiency ozone catalytic filler coordinated integrated machine through the first flexible connection 2 to carry out the main treatment of odorous substances. After passing through the air inlet 3, the fermentation waste gas first passes through the plasma generating disk 7 to achieve the effect of sterilization and deodorization, and then passes through the deozonation filler on the deozonation filler drawer 11, the air outlet 12, and the second flexible connection 8 in turn, and is finally transported from the induced draft fan 13 to the chimney 9 to meet the emission standards. While sterilizing and deodorizing, ozone is also removed, and most of the pollutants are removed in the plasma link.
