Technical Field

[0001] The utility model relates to an inorganic-organic combined tubular ultrafiltration device, belonging to the technical field of water treatment. Background Art

[0002] At present, tubular ultrafiltration devices have shown great potential in many fields with their unique filtering mechanism and high filtering efficiency. In the field of water treatment, the application of ultrafiltration equipment will continue to expand, which can effectively remove tiny particles and organic matter in the water and ensure the water quality of the effluent. In the fields of food, medicine, etc., ultrafiltration equipment can be used for the clarification and sterilization of beverages such as juice and beer, as well as the concentration, purification and pyrogen removal of drugs, to improve the quality and safety of products. In addition, with the strengthening of environmental protection policies and the improvement of people's environmental awareness, the application of ultrafiltration equipment in the field of environmental protection will also be further promoted, effectively removing harmful substances in wastewater, reducing pollution to the environment, and realizing the resource utilization of wastewater.

[0003] Conventional tubular ultrafiltration equipment mainly includes inorganic ceramic tubular ultrafiltration and organic tubular ultrafiltration, which are two independent treatment devices. When faced with different treatment process conditions, the initial investment cost of enterprises will be greatly increased;

[0004] The conventional flushing method of existing tubular ultrafiltration equipment is positive flushing. Due to the complexity and diversity of the water quality to be treated, pollutants with high viscosity often adhere to the inner wall of the membrane tube. Conventional positive flushing cannot meet the cleaning effect, which greatly affects the production efficiency and increases the operating cost.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create an inorganic and organic combined tubular ultrafiltration equipment to make it more valuable for industrial use. Summary of the invention

[0008] Furthermore, two pipelines are provided on the top of the backwash system, one of which is provided with an exhaust valve, and the other is provided with an air intake valve and a pressure reducing valve, and a water production outlet valve is provided on the pipeline between the backwash system and the water production barrel.

[0009] Furthermore, the raw water inlet pipeline and the inorganic tubular membrane group are connected through an inorganic water inlet pipeline, a valve a is provided on the inorganic water inlet pipeline, and a valve b is provided between the raw water inlet pipeline and the organic tubular membrane group.

[0010] Furthermore, the bottom of the inorganic tubular membrane group is connected to the cleaning bucket through an inorganic water production pipeline and an inorganic flushing return water pipeline.

[0011] Furthermore, the end of the organic tubular membrane group is connected to the cleaning bucket through an organic concentrated water return pipe and an organic flushing water return pipe.

[0012] Furthermore, the bottom of the inorganic tubular membrane group is connected to the raw water tank through a concentrated water return pipe.

[0013] Furthermore, the end of the organic tubular membrane group is connected to the raw water tank through a concentrated water return pipe.

[0014] Furthermore, the inorganic water production pipeline is provided with a valve c, and the organic water production pipeline is provided with a valve d.

[0015] By means of the above scheme, the present invention has at least the following advantages:

[0016] (1) The present invention combines inorganic ceramic tubular ultrafiltration with organic tubular ultrafiltration. In view of the complexity and diversity of current water quality treatment, the present invention improves the dynamism of the equipment to a greater extent, while also reducing the investment cost of the enterprise.

[0017] (2) The present invention is provided with a tubular ultrafiltration backwashing device, which can use the "gas-cap-water" method to thoroughly remove the pollutants remaining on the inner surface of the tubular membrane when conventional forward flushing cannot effectively clean the tubular membrane.

The pipeline between the backwash system 6 and the water production bucket 7 is provided with a water production outlet valve 64;

[0034] The working principle of the utility model is as follows:

[0035] In actual use of the utility model, due to the complexity and diversity of the wastewater to be treated, it is necessary to select an appropriate process for treatment according to water quality conditions. The specific means are: switching is achieved by adjusting valves a, b, c and d. When inorganic tubular ultrafiltration is required, valves a and c are opened, and valves b and d are closed; if organic tubular ultrafiltration is required, valves b and d are opened, and valves a and c are closed.

[0036] When the backwash system 6 is in use, the produced water delivery pipeline 12 is connected to the bottom of the backwash system 6 through a sanitary clamp. In the normal operating mode, the ultrafiltration produced water enters from the bottom of the backwash tank through the produced water delivery pipeline 12, and is exhausted by opening the exhaust valve 61. After the exhaust is completed, the exhaust valve 61 is closed, and the produced water enters the rear end water production barrel through the pipeline after passing through the produced water outlet valve 64; in the tubular ultrafiltration cleaning mode, first close the produced water outlet valve 64 and the exhaust valve 61, open the air intake valve 62, and connect compressed air to the air intake end of the pressure reducing valve 63. By adjusting the pressure reducing valve 63, the air intake pressure is controlled at 15-25KPa. The clear liquid in the backwash storage tank enters the membrane module tube side from the membrane module shell side under the pressure of the gas, and at the same time, the pollutants adhering to the inner wall of the membrane tube are washed away, thereby achieving the cleaning of the tubular ultrafiltration.
