Description

Technical Field

[0001] This utility model relates to the field of acetylene production technology and is a filter device for clearing and filtering overflow liquid from an acetylene generator. Background Technology

[0002] In the wet acetylene production process, the overflow liquid from the acetylene generator plays a crucial role. It is not only key to maintaining production continuity and safety but also directly affects the purity and production efficiency of the acetylene. This liquid is responsible for removing solid impurities and residues generated during the reaction, ensuring that the output acetylene gas is pure and free of impurities. Simultaneously, it also serves a cooling function, absorbing the heat released during the reaction and preventing temperature runaway within the reactor, thereby ensuring the stability and safety of the reaction.

[0003] To maintain liquid level balance within the generator and ensure uninterrupted reaction, the overflow liquid is recycled. This process not only improves resource utilization but also reduces raw material waste. Furthermore, the overflow liquid neutralizes any acidic substances that may be generated during the reaction, effectively reducing their corrosive effects on the equipment. Simultaneously, it recovers incompletely reacted raw materials and other useful substances, further enhancing the overall utilization rate of raw materials.

[0004] In terms of environmental protection, the treatment of overflow liquid can significantly reduce pollution. After treatment, the content of harmful substances in the overflow liquid is reduced, meeting emission standards and environmental protection requirements, thus embodying the concept of green production. Therefore, the treatment and recycling of overflow liquid is not only a necessary step in the acetylene production process but also a key measure for achieving environmental protection and sustainable development.

[0005] However, current methods rely on transfer pumps and piping systems to transport the overflow to the treatment point, which poses certain risks in large-scale production plants. Since production plants require continuous operation, a blockage in the transfer pump can severely impact the entire production process. Therefore, measures must be taken to intercept large impurities in the overflow before it enters the transfer pump to prevent blockage.

[0006] In traditional filtration processes, basket filters are widely used to intercept large impurities due to their simple structure and low cost. However, this type of filter has certain limitations in practical applications. Large impurities easily accumulate and clog basket filters, which not only affects the overflow effect of the generator but also requires regular cleaning during production to ensure the normal operation of the filter. This cleaning work not only increases labor intensity but also poses safety risks due to acetylene gas leakage. Therefore, improving existing filtration processes and developing more efficient filtration equipment is particularly important. Summary of the Invention

[0007] This utility model provides an acetylene generator overflow liquid cleaning and filtration device, which overcomes the shortcomings of the prior art and can effectively solve the problem that impurities in the overflow liquid of existing acetylene generators are prone to accumulate and clog in basket filters.

The end cap 3 is fixedly installed at the upper end of the filter body 1, and the gate valve 4 is fixedly installed at the lower end of the filter body 1. The collection cylinder 5 is fixedly installed at the lower end of the gate valve 4. An inlet pipe 20 that can communicate with the inside of the filter body 1 is provided on the upper outer side, and an inlet pipe 20 that can communicate with the inside of the filter body 1 is provided on the lower outer side. The filter body 1 has a filter cartridge 2 installed inside the filter body 1 with its lower end located on the upper side of the valve plate of the slide valve 4. The filter cartridge 2 is cylindrical with its upper and lower ends connected. The upper end of the filter cartridge 2 is located below the inlet pipe 20.

During use, the cylindrical filter body 1, which runs vertically through the filter, is equipped with a slide valve 4, which facilitates the direct discharge of impurities accumulated in the filter cartridge 2 into the collection cartridge 5. The lifting cylinder 6 drives the lifting rod 8 to move up and down within the filter body 1, allowing the cleaning component to clean the inner wall of the filter cartridge 2, thus avoiding the removal of impurities adhering to or clogging the filter cartridge 2.

[0024] The above-mentioned acetylene generator overflow liquid cleaning and filtration device can be further optimized and / or improved according to actual needs:

[0025] Example 2: As shown in the attached document Figure 1 , 2 As shown in Figure 3, the cleaning assembly includes a cleaning brush 9, a fixing ring 10, and fixing rods 11.

The lifting cylinder 6 completes the up-and-down lifting action, quickly removing accumulated impurities and residues inside the filter cartridge 2, thereby improving cleaning efficiency. Furthermore, traditional cleaning methods often require manual operation by workers, resulting in high labor intensity. Using a lifting cylinder 6 to drive the cleaning brush 9 for automated cleaning significantly reduces worker labor intensity, improves the working environment, and reduces the frequency of equipment downtime for manual cleaning due to increased cleaning efficiency, thus reducing downtime during production and improving production efficiency.

In addition, by using a known controller, the spray pipeline is fixedly connected to the liquid inlet hole on the upper outer side of the lifting rod 8, and a solenoid valve is installed on the spray pipeline. By controlling the solenoid valve and the lifting cylinder 6 through the controller, the cleaning brush 9 and the annular pipe 12 can be moved up and down and the spray can be automatically started and stopped, reducing manual intervention and improving the level of production automation. The automatic spraying and cleaning system reduces the workload of manual cleaning, and lowers labor intensity and labor costs.
