Description

Technical Field

[0001] This utility model relates to the field of circuit board incineration waste gas purification technology, specifically a multi-stage filtration circuit board incineration waste gas purification device. Background Technology

[0002] As is well known, circuit board incineration is a common disposal method in modern electronic waste treatment. However, this process generates a large amount of waste gas, which often contains complex pollutants, including but not limited to heavy metal particles, organic matter, and acidic gases. If these gases are directly released into the atmosphere without effective treatment, they will not only cause serious environmental pollution but may also have adverse effects on human health. To effectively remove these harmful substances, multi-stage filtration technology is usually required to gradually reduce the content of various pollutants in the waste gas. Although traditional waste gas purification equipment can meet certain purification requirements, its purification efficiency is gradually becoming insufficient as environmental standards become increasingly stringent. After long-term operation, impurities in the waste gas will gradually accumulate on the filter components, leading to a decrease in filtration efficiency. The efficiency of waste gas purification systems declines, especially when dealing with exhaust gases containing large amounts of fine particulate matter. This not only reduces equipment efficiency but also increases energy consumption and maintenance costs. Existing waste gas purification devices often require shutdown for cleaning or replacing filter components, which poses a significant challenge for continuous industrial processes. Furthermore, manual cleaning is not only labor-intensive but also difficult to thoroughly remove all impurities, posing a risk of secondary pollution. Most waste gas purification systems on the market currently lack efficient automatic cleaning mechanisms, requiring frequent manual intervention from users for cleaning operations. This places high demands on the professional skills of operators and increases management costs. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a multi-stage filter circuit board incineration waste gas purification device, which has the following beneficial effects:

[0015] This multi-stage filtration circuit board incineration exhaust gas purification device removes solid particles of different sizes and some harmful gas components from the incineration exhaust gas through multi-stage filtration components. Two symmetrically arranged filter tanks control the exhaust gas flow direction via a three-way valve. While one filter tank is being flushed or maintained, the other can continue its filtration task, enabling online cleaning without shutting down the machine. This significantly improves the continuity and stability of equipment operation, making it suitable for continuous industrial production scenarios. The nozzles in the flushing mechanism are mounted on a rotatable turntable, and with the help of a drive motor and gear ring transmission system, the nozzles can rotate during the flushing process, ensuring comprehensive coverage of the filtration system. The component surface enhances rinsing efficiency and cleanliness. After the rinsing pipe is connected to high-pressure liquid, the water flow can automatically remove impurities from its own channels through the nozzle, avoiding nozzle clogging and reducing the workload of manually clearing the nozzles periodically, thus improving the reliability of system operation. The rinsing pipe and the turntable are connected by a sealed bearing, which ensures smooth liquid transmission and prevents leakage. After rinsing, the sewage and residual impurities can be quickly discharged through the sewage discharge mechanism to avoid pollution residue. The entire rinsing and sewage discharge process can be automated through the control system, eliminating the need for frequent manual intervention, significantly reducing labor intensity and improving the intelligence level of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model relates to a multi-stage filter circuit board incineration waste gas purification device, comprising a filter box 1, wherein the filter box 1 has a filter groove inside, and the filter groove is provided with a flushing mechanism, a sewage discharge mechanism, and a multi-stage filtration assembly. An installation pipe 2 is provided between the filter groove and both sides of the filter box 1. There are two filter grooves arranged symmetrically. A three-way valve 3 is provided between the two installation pipes 2 located on one side of the filter box 1. The three-way valve 3 is provided with an external connecting pipe 4. The flushing mechanism includes a sealing cover 5, and a flushing pipe 6 and a drive motor 7 are provided at the top of the sealing cover 5. A flushing groove is provided between the inside of the sealing cover 5 and the filter groove. The inside of the sealing cover 5 is provided with... A bearing housing 8 is provided with a turntable 9. A nozzle 10 is located at the bottom of the turntable 9 and connects to the interior of the turntable 9. A flushing pipe 6 extends into the interior of the turntable 9 and is equipped with a sealed bearing 11. A gear ring 12 is located at the top of the turntable 9. The output end of the drive motor 7 extends into the interior of the sealing cover 5 and is equipped with a gear 13, which meshes with the gear ring 12. In this embodiment, one of the two external pipes 4 is connected to the exhaust gas discharge pipe, and the other external pipe 4 is connected to a pipe for subsequent processing, such as a desulfurization tower. Through the three-way valves 3 on the two external pipes 4, the exhaust gas can pass through only one of the two filter tanks. The waste gas is filtered through a multi-stage filtration system in a filter tank to remove impurities before being discharged into the next process. However, over time, excessive impurities can clog the multi-stage filtration system, reducing its effectiveness. By controlling two three-way valves 3, the waste gas can be filtered through another multi-stage filtration system in a separate filter tank. The flushing pipe 6 in the flushing mechanism of the filter tank with accumulated impurities is connected to the liquid supply system, allowing liquid to enter the turntable 9 through the flushing pipe 6. The liquid then flushes the multi-stage filtration system through the nozzle 10. The output of the drive motor 7 is controlled to rotate the gear 13, which in turn rotates the gear ring 12. The friction between the gear ring 12 and the bearing seat 8 and the turntable 9 is then applied to the flushing system. The sealed bearing 11 between the washing pipes 6 enables the turntable 9 to rotate at a stable angle, thereby rotating the nozzle 10. This allows for more efficient rinsing of impurities and particles from the multi-stage filter assembly. The flushing liquid and impurities can then be discharged directly by opening the drain mechanism, achieving automatic and efficient rinsing. When rinsing another filter tank, the flushed filter tank can be used for filtration again. This ensures that the rinsing process does not affect the filtration of incineration exhaust gas. During filtration, exhaust gas impurities and dust enter the nozzle 10, requiring no manual cleaning. After the flushing liquid is connected to the washing pipe 6, the water pressure can flush away the impurities and dust clogging the nozzle 10.

[0023] To facilitate efficient filtration of incineration exhaust gas, in this solution, the multi-stage filtration assembly includes a filter layer 14, which is installed inside the filter tank and multiple layers are provided. By displacing the multiple filter layers 14 in the filter tank, exhaust gas impurities can be filtered efficiently and multiple times.

[0024] In order to efficiently rinse the multi-stage filter components, in this solution, the nozzle 10 is provided in multiple and arrayed configurations. By using multiple and arrayed nozzles 10, the multi-stage filter components can be rinsed more efficiently.

[0025] To facilitate the discharge of rinsing liquid and impurities, the sewage discharge mechanism in this solution includes a sewage discharge pipe 15. The sewage discharge pipe 15 is installed at the bottom of the filter box 1 and connected to the filter tank. The sewage discharge pipe 15 is equipped with a sewage discharge valve 16. During rinsing, the sewage discharge valve 16 is opened to allow the rinsing liquid and impurities to be discharged through the sewage discharge pipe 15. After rinsing is completed, the sewage discharge valve 16 is closed, thereby facilitating the filtration operation of the multi-stage filtration components in the filter tank.

[0026] In order to facilitate the operation of the drain valve 16, in this solution, the drain valve 16 is an electric valve, which makes it easy to operate the valve.

[0027] To facilitate the connection of the four external pipes, in this design, both the external pipe 4 and the sewage pipe 15 are equipped with flanges 17. The flanges 17 facilitate the connection of the four external pipes, and the flange connection method has the characteristics of good connection stability and good sealing, thereby ensuring a stable and reliable connection of the four external pipes.

[0028] In order to ensure the control accuracy of turntable 9, in this solution, the drive motor 7 is a servo motor. The high rotational accuracy of the servo motor can improve the control accuracy of turntable 9.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
