[0002] As is well known, in the process of processing liquid-phase ammonia-containing mixtures, how to efficiently and reliably separate pure ammonia and its by-products is a key technical challenge. Traditional separation methods usually rely on a combination of physical filtration and chemical treatment. However, these methods have many shortcomings in practical applications.

[0003] Traditional filtration systems often lack effective automatic cleaning mechanisms. As operating time increases, impurities gradually accumulate on the surface of the filter screen, leading to a significant decrease in filtration efficiency. This may require frequent shutdowns for manual cleaning or filter screen replacement, which not only increases operating costs but also seriously affects production efficiency. Furthermore, cleaning the filter screen often requires the use of large amounts of water or other cleaning agents, which is not only wasteful of resources but also prone to secondary pollution.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4 A separation device for ammonia-containing liquid-phase mixtures includes a separation chamber 1, a filter chamber 2, a filter screen 3, a moving device, and a filter screen cleaning device. A connecting pipe 4 is installed at the top of the separation chamber 1, and a pump body 5 is installed on the outer wall of the connecting pipe 4. The filter chamber 2 is installed at the top of the connecting pipe 4, and an inlet pipe 6 is installed at the top of the filter chamber 2. The filter screen 3 is installed inside the filter chamber 2, and a collection hood 7 is installed on the side wall of the filter chamber 2 via the moving device. A fan 8 is installed at the top of the separation chamber 1, and the fan 8 and the collection hood 7 are connected via the filter screen cleaning device. A nanofiltration membrane assembly is installed inside the separation chamber 1, and an outlet pipe 9 is installed on the side wall of the separation chamber 1. In this embodiment, during use, the ammonia-containing liquid-phase mixture enters the filter chamber 2 through the inlet pipe 6 and mixes... The material first enters the filter box 2 equipped with filter screen 3 for preliminary filtration to remove large particulate impurities. After preliminary filtration, the liquid flows into the separation box 1 through the connecting pipe 4 and is pressurized by the pump body 5 to drive the liquid flow. Here, it is further processed by the nanofiltration membrane module. The nanofiltration membrane can effectively remove divalent or polyvalent ions and large molecular weight organic matter, while allowing monovalent ions and water to pass through, thereby achieving effective separation of ammonia. The liquid is discharged through the outlet pipe 9. As the operating time increases, impurities may accumulate on the filter screen 3, affecting permeability and efficiency. At this time, the filter screen cleaning device is activated, using the negative pressure created by the fan 8 or adsorption on the surface of the filter screen 3 to achieve online automatic cleaning. The moving device drives the collection hood 7 to move synchronously to clean all aspects of the filter screen. The "filter screen 3 + nanofiltration membrane" two-stage separation mechanism, coarse first and then fine, improves the overall separation efficiency. The filter screen cleaning device and the moving collection hood 7 work together to achieve online automatic cleaning, reducing manual intervention. The design of the filter screen cleaning device keeps the filter screen 3 clean, extends its service life, reduces downtime, and improves the reliability of the overall equipment.

[0021] Preferably, in this embodiment, the filter cleaning device includes a telescopic pipe 10, a transmission pipe 11, a collection box 12, and a filter plate 13. The collection box 12 is installed at the end of the top wall of the separation box 1 away from the fan 8. The filter plate 13 is installed inside the collection box 12. The transmission pipe 11 is installed on the side wall of the collection box 12. The telescopic pipe 10 is installed at the end of the transmission pipe 11 away from the collection box 12, penetrating the side wall of the filter box 2. The output end of the telescopic pipe 10 is connected to the collection cover 7. During the filtration process, as the liquid mixture continuously flows through the filter screen 3, some impurities will gradually adhere to the surface of the filter screen 3, causing blockage. The fan 8 is started by the control system, and the high-pressure air generated by the fan 8... The high-speed airflow enters the filter cleaning device through the collection hood 7. Loose impurities are sucked into the collection hood 7 and enter the telescopic pipe 10, forming a directional airflow. At the same time, under the negative pressure of the fan 8, the airflow is transported to the collection box 12 through the transmission pipe 11. After the impurities enter the collection box 12 with the airflow, they first come into contact with the filter plate 13 installed in the box. The filter plate 13 is a porous metal mesh used to intercept larger particles of impurities and prevent them from entering subsequent equipment. Through the airflow cleaning system composed of the fan 8, telescopic pipe 10, collection hood 7 and collection box 12, the filter screen 3 is cleaned efficiently and continuously, improving the overall automation level of the equipment. The negative pressure adsorption can effectively remove various types of impurities attached to the filter screen.

[0022] Preferably, in this embodiment, the moving device includes an electric telescopic rod 14. The electric telescopic rod 14 is installed on the outer wall of the filter box 2. The output end of the electric telescopic rod 14 passes through the outer wall of the filter box 2 and is connected to the side wall of the collection cover 7. When the control system needs to clean the filter screen 3, it will issue a command to start the electric telescopic rod 14. After receiving the signal, the electric telescopic rod 14 begins to extend outward, pushing the collection cover 7, whose output end is connected to it, to move in a straight line along the surface of the filter screen 3. As the electric telescopic rod 14 gradually extends, the collection cover 7 is smoothly pushed towards the other side of the filter screen 3. During this process, the airflow generated by the blower 8 enters the telescopic pipe 10 through the collection hood 7 and acts on the surface of the filter screen 3. Under negative pressure, these impurities are sucked into the collection hood 7 and transported to the collection box 12 through the transmission pipe 11. When the collection hood 7 reaches the other end of the filter screen 3, the electric telescopic rod 14 begins to retract, driving the collection hood 7 back to the starting position in the opposite direction, completing a complete cleaning cycle. According to actual needs, a single round trip or multiple round trip cleaning mode can be set. The telescopic pipe can extend and retract according to the movement of the collection hood 7 to ensure that the surface of the filter screen 3 is thoroughly cleaned.

[0023] Preferably, in this embodiment, a moisture-absorbing cotton 15 is installed inside the air outlet of the fan 8. Since there will be residual moisture in the collected residue, the moisture-absorbing cotton 15 can absorb this moisture, as well as other residual gases inside, reducing the moisture and other substances content of the exhaust air.

[0024] Preferably, in this embodiment, the moisture-absorbing cotton 15 is made of activated carbon composite moisture-absorbing material. Activated carbon is known for its highly developed pore structure and huge specific surface area, which can effectively adsorb a variety of gas molecules, including ammonia, volatile organic compounds (VOCs), etc. The composite moisture-absorbing material not only retains the advantages of activated carbon, but also enhances its ability to absorb moisture, so that it can control humidity while removing harmful gases.

[0025] Preferably, in this embodiment, a one-way valve 16 is provided in the air duct between the fan 8 and the collection hood 7. The one-way valve 16 can ensure that the airflow flows in only one direction (i.e. from the fan 8 to the collection hood 7), preventing untreated air or gas from entering the system in reverse. This helps to maintain the system's sealing and cleanliness, and ensures that the filtration efficiency is not affected by external factors.

[0026] Preferably, in this embodiment, the side wall of the collection box 12 is provided with a slag discharge port 17, and a cap 18 is threadedly installed at the slag discharge port 17. The collection box 12 is used to receive impurity particles adsorbed from the filter screen 3. After long-term operation, a certain amount of waste slag will accumulate. The slag discharge port 17 can conveniently discharge these impurities periodically, preventing blockage of the transmission channel or affecting subsequent airflow circulation. The slag discharge port 17 adopts a threaded connection to the cap 18, which has stronger sealing performance and can effectively prevent the cap 18 from loosening due to vibration or pressure changes during equipment operation, thereby causing gas leakage or impurity overflow, ensuring the cleanliness and safety of the operating environment.

[0027] Preferably, in this embodiment, support legs 19 are installed at the four corners of the bottom of the separation box 1. The support legs 19 provide a stable foundation to ensure that the separation box 1 remains level and stable even on uneven ground, preventing tilting or tipping due to slight collisions or uneven ground.
