Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a portable self-shielded electron accelerator irradiation device for wastewater treatment. Background Technology

[0002] Currently, there are various methods for water pollution treatment, such as chemical methods like oxidation-reduction and physical methods like adsorption and precipitation. Among these, electron beam irradiation for wastewater treatment is gaining increasing attention due to its cleanliness, high efficiency, lack of secondary pollution, and ability to decompose and treat various pollutants. However, most electron beam irradiation devices for wastewater treatment currently use a tower-like structure, which means the equipment cannot be moved after it is put into use, thus limiting its application range.

[0003] Currently, most wastewater is discharged centrally, requiring the laying of long-distance pipelines or the establishment of nearby wastewater treatment plants for treatment. However, some wastewater is generated in scattered locations that are inconvenient to collect and are far from traditional fixed wastewater treatment facilities. Because these facilities cannot be put into use on-site in a timely manner, wastewater discharge cannot be effectively treated, which can easily lead to further pollution.

[0004] Therefore, designing a new type of wastewater treatment device that is mobile and has a wide range of applications is an urgent problem to be solved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a portable, self-shielded electron accelerator irradiation device for wastewater treatment, comprising:

[0006] The main body is a movable container.

[0007] An electron accelerator, housed within the movable enclosure, is used to provide an irradiated electron beam;

[0008] A wastewater processor, housed within the movable enclosure and located below the irradiation window of the electron accelerator, is used to receive irradiated electron beams and treat wastewater.

[0009] A lower water tank is connected to the wastewater processor and located below the electron accelerator for receiving treated wastewater;

[0010] A control system, located within the movable housing and connected to the electron accelerator, is used to control the operation of the electron accelerator.

[0011] A shielding body that at least covers the irradiation window and the wastewater processor, and is used to at least shield the irradiation energy of the irradiation window and the wastewater processor.

Detailed Implementation

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figure 1As shown, this application provides a mobile self-shielded electron accelerator irradiation device for wastewater treatment. The main body of the device is a mobile box with a movable structure, which can be wheels or tracks. The mobile box also has a connecting component 7, which can be used to connect power equipment, such as various types of powered vehicles (cars, forklifts, etc.). The device can be moved to the area requiring wastewater treatment by means of the power equipment. The model and size of the power equipment can be selected according to the geographical environmental conditions of the wastewater area. A power unit can also be directly installed inside the mobile box for direct control of the device's movement.

[0032] An electron accelerator 5 is housed within a movable enclosure. The electron beam generator of the electron accelerator 5 can be a resonant type or another type. The electron accelerator 5 is fixed to the top of the enclosure, and the electron beam irradiation window 9 faces downwards. Figure 2 As shown, a wastewater processor 10 is positioned below the electron beam irradiation window 9. After receiving wastewater, the wastewater processor 10 sprays the wastewater out as a water film. The electron beam generated by the electron accelerator 5 irradiates the water film after reaching a preset width through the electron beam irradiation window 9. Under the irradiation of the electron beam, wastewater molecules generate strong oxidizing particles such as hydroxyl radicals (·OH) and hydrogen peroxide (H2O2), and also generate almost an equal amount of hydrated electrons (electrons). aq - Strong reducing particles such as free radicals and hydrogen atoms (H·) can react with organic matter in wastewater that is difficult to degrade naturally, mineralizing or destroying the structure of organic matter, improving biochemical properties or sedimentation performance, thereby achieving the purpose of removing pollutants. The treated wastewater is received and temporarily stored in the downflow tank 8, which can be connected to the outside of the device through an inlet pipe.

[0033] Because the electron accelerator 5 emits significant radiation during operation, a shielding enclosure 4 is installed within the movable housing to ensure the safety of surrounding personnel. The shielding enclosure 4 can be made of iron and lead and is assembled using a stepped interface. The protection requirements of the shielding enclosure 4 are designed according to the HJ 979-2018 standard, whereby the radiation dose equivalent rate around the equipment is calculated using the formula... The measured dose equivalent rate was less than 1 μSv / h, and the dose equivalent rate in the area accessible to personnel outside the electron accelerator irradiation device, at least 30 cm above the outer surface of the shield and beyond, was required to not exceed 2.5 μSv / h. To meet safety requirements, the shield 4 should at least cover the electron beam irradiation window 9, the wastewater treatment unit 10, and the under-beam water tank 8. In further improvements, to prevent irradiation leakage, the shield 4 should also cover part of the inlet pipe of the wastewater treatment unit 10 and part of the outlet pipe of the under-beam water tank 8. The shield 4 is equipped with a movable shielding door 11 for easy maintenance and inspection of the internal components. The shield 4 is equipped with a lighting system that automatically activates when the shielding door 11 is opened.

[0034] In some specific embodiments, an ozone processor 6 is also installed inside the movable housing to promptly treat the small amount of ozone generated during the electron beam irradiation treatment of wastewater. The input end of the ozone processor 6 is connected to the interior of the shield 4, continuously drawing in ozone-containing air generated during the irradiation process. The output end of the ozone processor 6 is connected to the outside of the movable housing, and the treated ozone is directly discharged into the atmosphere.

[0035] In some specific embodiments, a control system is also installed inside the movable enclosure. The control system includes a control cabinet 1, a starter cabinet 2, and an intermediate frequency power supply 3. Specifically, as shown in patent CN222674152U, the intermediate frequency power supply 3 includes a three-phase power input module, a rectifier module, and an inverter module connected in sequence. The output terminal of the inverter module is connected to the primary coil of the electron accelerator. A matching capacitor and a matching inductor are provided between the inverter module and the primary coil. The matching capacitor, matching inductor, and primary coil together form an LLC series resonant circuit. This design allows the entire circuit to operate near the series resonant point, improving overall efficiency.

[0036] In some specific embodiments, to improve the utilization of the internal space of the device, the control system is located above the movable structure, and the electron accelerator 5 is located on the side away from the movable structure. A side door is also provided at the location corresponding to the control system in the movable enclosure, for manual setup or maintenance of the control system.

[0037] In some specific embodiments, a temperature sensor and a cooling system are also installed within the movable enclosure. The temperature sensor is used to sense the temperature of various components inside the device in a timely manner. The cooling system includes a control system cooling module for cooling the control system and an electron accelerator cooling module for cooling the electron accelerator 5. The cooling system can be an air cooling system or a liquid cooling system.

[0038] Traditional wastewater treatment plants are constructed by casting concrete after site selection, and once completed, they are fixed and cannot be moved. Fixed plants are effective for treating centralized wastewater, but they are inconvenient for treating decentralized wastewater. If corresponding wastewater treatment plants are built for each decentralized wastewater source, or if long-distance transportation pipelines are laid, the operating costs for customers will be greatly increased.

[0039] To address the aforementioned deficiencies, the mobile self-shielded electron accelerator irradiation device designed in this application integrates an electron accelerator, a wastewater treatment device, a shield, and a control system into a mobile housing. When wastewater in a certain area needs to be treated, this application can be directly driven to that area by a power source, and the wastewater can be pumped into the wastewater treatment unit by a wastewater pump. After being treated by electron beam irradiation, the wastewater can be temporarily stored in an internal under-beam water tank or directly discharged to a designated location.

[0040] This application offers significant convenience and efficiency for wastewater treatment. The device innovatively employs a resonant transformer instead of a high-frequency, high-voltage transformer as the electron beam generator, improving the equipment's energy conversion efficiency. Simultaneously, it uses lead and iron as the shielding material instead of the traditional concrete shielding structure, effectively reducing the equipment's size and improving space utilization.

[0041] The embodiments of this utility model have been described in detail above, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
