Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a plasma aeration sewage deep treatment device. Background Art

[0002] Sewage refers to polluted water discharged from domestic and industrial sources. Water that has lost its original function is simply called sewage. It primarily refers to water used in daily life, contains a high concentration of organic matter, and is relatively easy to treat. During sewage treatment, specific methods and equipment are used to force air into the sewage, allowing the water in the tank to come into contact with the air and oxygenate it. This agitation accelerates the transfer of oxygen from the air into the liquid, preventing suspended matter from sinking and enhancing contact between organic matter and microorganisms and dissolved oxygen, leading to the oxidation and decomposition of organic matter in the sewage. This forced oxygenation of the sewage is called aeration.

[0003] The use of plasma for sewage treatment is an emerging organic sewage treatment and disinfection technology. Generally, high-energy plasma is used to ionize water bodies, producing a large number of strong oxidizing particles in the water, such as hydroxyl free radicals, which can undergo advanced oxidation reactions on organic matter in the water; or the air is directly ionized to produce ozone ions, oxygen cations and other strong oxidizing substances, which effectively increase the dissolved oxygen in the water after entering the water body.

[0004] However, in the prior art, a plasma generator is usually located in an aeration treatment tank. As the working time of the plasma generator increases, it needs to be regularly maintained. During the maintenance, the overall sewage treatment process needs to be in a temporary state, which in turn affects the overall sewage treatment efficiency.

DETAILED DESCRIPTION

[0024] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0025] according to Figure 1-Figure 7 As shown, this embodiment proposes a plasma aeration sewage deep treatment device, including an aeration treatment tank 1, an aeration fan 2 and a plasma generator 3. The aeration treatment tank 1 is connected to the plasma generator 3 through the aeration fan 2. An aeration pipe 26 is installed on the inner side of the aeration treatment tank 1, and the input end of the aeration pipe 26 is connected to the output end of the aeration fan 2 through a pipeline. The specific aeration treatment tank 1 itself is designed separately from the aeration fan 2 and the plasma generator 3, so that corresponding repairs and maintenance can be performed when other situations occur in the plasma generator 3. At the same time, the shape of the aeration pipe 26 is adapted to the shape of the aeration treatment tank 1. An aeration nozzle 27 is installed on the aeration pipe 26, and the aeration nozzles 27 are evenly arranged in several groups. A fixed shaft 28 is provided above the aeration pipe 26, and one end of the fixed shaft 28 is connected to the aeration treatment tank 1 through a bearing. There are several groups of fixed shafts 28, and stirring plates 29 are installed on the outside of the several groups of fixed shafts 28. There are several groups of stirring plates 29, such as Figure 1 As shown, in this embodiment, three groups of fixed shafts 22 are provided, and each group of fixed shafts 22 corresponds to five groups of stirring plates 23. Therefore, when the gas in the aeration pipe 26 is ejected through the aeration nozzle 21, the gas will rise in the aeration treatment tank 1 (the aeration pipe 26 is arranged in the lower part of the aeration treatment tank 1, close to the bottom), and when the aeration nozzle 21 ejects the gas, a certain impact force is generated, and then in the process of its rising, it contacts the stirring plate 23, which is then in an active state, thereby achieving the effect of disturbing the sewage, which is conducive to full contact between the sewage and the gas.

[0026] A support shell 4 is installed below the plasma generator 3, and a maintenance chamber 5 is provided on the inner side of the support shell 4. Protective doors 6 are installed on the support shell 4 at both ends of the maintenance chamber 5. The corresponding plasma generator 3 itself is protected by an insulating shell, and a support shell 4 is provided below it, so that the plasma generator 3 is at a high place and is not easy to collide with other equipment or components. At the same time, a maintenance channel is provided in the inner cavity of the support shell 4 (maintenance chamber 5). When performing maintenance, the staff enters the maintenance chamber 5 by opening the protective door 6. Furthermore, in this embodiment, the plasma generating component in the plasma generator 3 can be transferred to the maintenance chamber 5 for maintenance, without affecting the working state of other plasma generating components. Then, the plasma generator 3 can be kept in working state while the plasma generating component is being maintained, thereby not affecting the efficiency of the deep treatment of sewage.

[0027] Further, an insulating assembly frame 7 is provided on the inner side of the plasma generator 3, and the insulating assembly frame 7 is provided with several groups. In this embodiment, there are five groups of insulating assembly frames 7, and a plasma generating assembly is installed on the inner side of each of the five groups of insulating assembly frames 7, wherein the plasma generating assembly includes an outer assembly frame 10 and an inner assembly frame 11. The outer side of the inner assembly frame 11 is connected to the outer assembly frame 10 through an insulating connector 12, and the insulating connector 12 is provided with several groups. In this embodiment, ten groups of insulating connectors 12 are installed on the outer side of each group of inner assembly frames 8, and serrated inner electrodes 13 are installed on both sides of the inner assembly frame 11, and the serrated inner electrodes 13 are provided with several groups. One side of each group of serrated inner electrodes 13 is provided with a plate-shaped outer electrode 14 on the outer assembly frame 10, and a plasma generating power supply is installed at the lower end of the corresponding insulating assembly frame 7. 31, and the plasma generating power supply 31 is connected to the insulating assembly frame 7 by bolts, and the plasma generating power supply 31 is electrically connected to the serrated inner electrode 13 and the plate-shaped outer electrode 14. Therefore, when working, the plasma generating power supply 31 works to provide a power source (high voltage in this embodiment) for the serrated inner electrode 10 and the plate-shaped outer electrode 11, and then uses air as a medium and high voltage to generate plasma between the inner and outer electrodes (the serrated inner electrode 10 and the plate-shaped outer electrode 11). Accompanied by the action of the aeration fan 2, the plasma enters the aeration pipe 26 and is then ejected by the aeration nozzle 21, thereby performing aeration deep treatment on the sewage in the aeration treatment tank 1, and then using plasma to degrade the pollutants into non-toxic and harmless substances. At the same time, when treating sewage, no other chemicals need to be added.

[0028] Further, the insulating assembly frame 7 is connected to the plasma generator 3 and the support shell 4 through a lifting assembly. An opening 8 is provided on the plasma generator 3 directly below the insulating assembly frame 7, and the opening 8 is connected to the maintenance cavity 5. Therefore, when the lifting assembly drives the insulating assembly frame 7 to move, it can pass through the opening 8. Specifically, a first connecting plate 15 is installed on the upper end of the insulating assembly frame 7, and a second connecting plate 16 is installed on the lower end of the insulating assembly frame 7 through a bracket. The size of the first connecting plate 15 is consistent with the size of the second connecting plate 16. The first connecting plate 15 and the second connecting plate 16 of the chess game are both connected to the lifting assembly. A slot 17 is provided, and the slots 17 are provided in several groups. In this embodiment, the slots 17 are evenly provided in six groups. The inner sides of the six groups of slots 17 are provided with an insert 18, and the insert 18 is connected to the external assembly frame 10. The slot 17 itself does not penetrate the insulating assembly frame 7. In this embodiment, the right end thereof is in a blocked state, while the left end is in a state of communication with the outside. When separating the external assembly frame 10, the staff only needs to use a tool or hand to apply a rightward force to the external assembly frame 10 to separate the external assembly frame 10 from the insulating assembly frame 7. Disassembly is convenient while installation is also convenient, thereby providing convenience for maintenance of the plasma generating assembly.

[0029] The specific lifting assembly includes two groups of symmetrically arranged threaded screws 21, the two ends of the threaded screw 21 are respectively connected to the plasma generator 3 and the support shell 4 through bearings, and the threaded screw 21 is driven by a motor 22. The motor 22 is located at the upper end of the plasma generator 3 and is fixedly connected to the plasma generator 3 through a bracket. At the same time, the threaded screw 21 passes through the first connecting plate 15 and the second connecting plate 16, and is connected to the first connecting plate 15 and the second connecting plate 16 through threads. A motor control end 23 is installed on the inner wall of the support shell 4. The motor control end 23 is electrically connected to the motor 22. Then, when the staff operates through the motor control end 23, the motor 22 driving the threaded screw 21 will simultaneously receive the corresponding electrical signal, and then start to drive the threaded screw 21 to rotate. Under the action of the threaded connection, the first connecting plate 15 and the second connecting plate 16 are driven to move up and down, thereby achieving the effect of driving the insulating assembly frame 7 to move.

[0030] A pad 19 is installed on the support shell 4 directly below the opening 8. Proximity switches 20 are installed at both ends of the pad 19. The output end of the proximity switch 20 is electrically connected to the lifting assembly, that is, the proximity switch 20 is electrically connected to the motor control terminal 23. The corresponding lower end of the second connecting plate 16 is installed with metal contacts, and the number and position of the metal contacts correspond to the proximity switch 20. When the insulating assembly frame 7 moves downward, the second connecting plate 16 also moves downward. When it contacts the pad 19, the metal contact contacts the proximity switch 20. The proximity switch 20 generates an electrical signal and sends it to the motor control terminal 23. The motor control terminal 23 then controls the motor 22 to stop. At this time, the insulating assembly frame 7 is in the preset position, and then subsequent work is carried out. Correspondingly, when a group of plasma generating components needs to be maintained, the corresponding plasma generating power supply 31 is first turned off, and then the corresponding lifting operation is performed.

[0031] An air inlet 9 is provided at one end of the plasma generator 3 away from the aeration fan 2, and the air inlet 9 is provided in several groups. A gas guide port 24 is installed on the inner side of the plasma generator 3, and the output end of the gas guide port 24 is connected to the input end of the aeration fan 2 through a pipe. An air guide cover 25 is also provided on the inner side of the plasma generator 3. The air guide covers 25 are evenly provided in several groups and are connected to the plasma generator 3 through a bracket. Several groups of air guide covers 25 are distributed between several groups of insulating assembly frames 7. When there are five groups of insulating assembly frames 7, there are four groups of air guide covers 25, which are distributed as follows: Figure 1 As shown, it mainly plays the role of air guidance.

[0032] A sealing layer 30 is provided between the opening 8 and the second connecting plate 16. The sealing layer 30 is elastic and has an arc-shaped end close to the second connecting plate 16. When the second connecting plate 16 contacts the pad 19, the first connecting plate 15 is located in the opening 8 and contacts the sealing layer 30. This mainly provides a certain sealing effect, so that the air intake direction of the plasma generator 3 is mainly concentrated at the air inlet 9.

[0033] A fill light is also installed in the supporting shell 4 to illuminate the supporting shell 4.

[0034] The left side below the opening 8 is provided with a hinge 32 on the plasma generator 3, and a support plate 33 is hinged on the hinge 32. The right side below the corresponding opening 8 is provided with a fixing member 34 on the plasma generator 3, and the fixing member 34 is provided with a slot 35, and one end of the support plate 33 is located in the slot 35, and one end of the support plate 33 can be moved out of the slot 35, so that the support plate 33 has a locking effect. In this device, it mainly plays a protective role. Since the first connecting plate 15 and the second connecting plate 16 are connected by a threaded screw 21, when an accident occurs and causes the connection to fail, the first connecting plate 15 and the second connecting plate 16 both fall downward, and the support plate 33 at this time plays an intercepting role to reduce the loss of the equipment. Correspondingly, when maintenance is required, the staff needs to manually move the corresponding support plate 33 so that it cannot play a blocking effect.
