Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a high-efficiency, energy-saving, reciprocating integrated ultrafiltration equipment. Background Technology

[0002] Ultrafiltration technology, as an advanced membrane separation technology, has been widely used in water treatment in recent years. Its basic principle is to use the pressure difference across the ultrafiltration membrane as the driving force to remove large molecular impurities such as suspended solids, colloids, bacteria, and viruses from the water, while allowing water molecules, inorganic salts, and small organic molecules to permeate, thereby purifying the water. Traditional ultrafiltration equipment often suffers from high energy consumption, large footprint, and difficult operation and maintenance. Furthermore, the ultrafiltration membrane in traditional equipment is often stationary, while research shows that static ultrafiltration membranes are less effective than those that are constantly in motion. Therefore, improving the ultrafiltration membrane from static purification to dynamic purification is a current need.

[0003] Among existing research findings, utility model patent CN218393119U discloses a circulating filtration device for pullulan production based on an ultrafiltration membrane. This device includes a filter box, an internal piston plate, and a detachably mounted ultrafiltration membrane plate. Multiple L-shaped fixing plates are fixedly connected to the side walls of the filter box, and a top plate is fixedly connected to the top of these L-shaped plates. An electric cylinder is installed at the bottom of the top plate, and its extension / retraction end is fixed to the top of the piston plate. Two reciprocating screws are rotatably inserted through the filter box, with gear plates fixedly connected to both ends. A gear plate is fixedly connected to the top of the piston plate, and the gear plate and gear plates mesh for transmission. A screw sleeve is rotatably connected to the periphery of the reciprocating screws. This device effectively prevents impurities from clogging the ultrafiltration membrane, reducing the probability of membrane damage. However, in actual use, it still cannot achieve multi-directional dynamic movement of the ultrafiltration membrane. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a highly efficient and energy-saving reciprocating integrated ultrafiltration device.

[0005] The technical solution of this invention is:

[0006] A high-efficiency and energy-saving reciprocating integrated ultrafiltration equipment includes an ultrafiltration membrane module housing and a circulation pipeline;

[0007] The ultrafiltration membrane module housing includes several membrane module collection frames inside. Each of the two rear sides of the top of the ultrafiltration membrane module housing is provided with a drive component for driving the membrane module collection frames to reciprocate synchronously.

[0008] The membrane module collection frame contains several membrane modules, each containing ultrafiltration membrane fibers made of hydrophilic PTFE. The top of the membrane module collection frame has a crossbeam with a slider at each end. The top of the ultrafiltration membrane module housing has a support beam on each side, with a slide rail on the support beam. The slider is slidably connected to the slide rail.

[0009] The drive assembly includes an electric cylinder and a drive motor for moving the electric cylinder, the electric cylinder being fixedly connected to each of the sliders located on one side of the support beam.

[0010] Furthermore, the circulation pipeline includes two sets, with the end of the circulation pipeline connected to the flow pump, and several butterfly valves are installed on the circulation pipeline.

[0011] Note: The inlet and outlet of water for each membrane module in the circulation pipeline is controlled by the butterfly valve.

[0012] Furthermore, an overflow pipe is provided on the upper part of one side of the ultrafiltration membrane module box, an air drain valve is provided on the bottom side of one side of the ultrafiltration membrane module box, a level gauge and a pH meter are provided on the top of the ultrafiltration membrane module box, and an inlet pipe is provided on one side of the top of the ultrafiltration membrane module box.

[0013] Note: The purified water is collected through the overflow pipe, and the top water in the ultrafiltration membrane module tank is monitored by a level gauge and a pH meter.

[0014] Furthermore, an equipment room is provided on the side opposite to the membrane assembly frame of the ultrafiltration membrane module housing. A control cabinet is provided in the equipment room, and a dosing tank and a cleaning water tank are also provided side by side in the equipment room. A sludge return pump, a product water pump, a backwash pump and a filter are also provided in sequence in the equipment room.

[0015] Note: The equipment room controls operations such as adding chemicals and replenishing water.

[0016] Furthermore, rollers are provided on both sides of the bottom of the membrane module collection frame, and a lifting component is provided at the bottom of the ultrafiltration membrane module housing in front of the rollers. The lifting component includes a rotating motor located at the bottom of the ultrafiltration membrane module housing. An approximately semi-cylindrical limiting block is provided at the end of the output shaft above the rotating motor. A groove is provided in the middle of the limiting block, and a wave-shaped limiting protrusion is provided inside the groove. An arc-shaped transition plate is provided on one side of the limiting protrusion. A sliding groove is provided on each side of the middle of the groove, and a sliding plate is provided inside the sliding groove. The top of the sliding plate is connected to the two sides of the limiting block and forms a continuous arc transition. The top of the membrane module collection frame is connected to the crossbeam through several telescopic rods.

[0017] Explanation: The lifting component can assist in controlling the movement direction of the membrane module's collection frame, enabling it to move in multiple directions during reciprocating motion. This results in a larger movement coverage area and a continuous vibration reciprocating motion mode, increasing the equipment's versatility and further improving the wastewater treatment effect.

[0018] Furthermore, a magnetic chuck is provided at the bottom of the membrane assembly frame at the front end of the roller, and the magnetic chuck engages with the slide plate to reset the slide plate.

[0019] Explanation: By using magnetic chucks to connect with the slide plate and reset it, the slide plate is automatically reset, thus enabling automatic switching between the two modes of the lifting component.

[0020] Furthermore, there are 3 membrane module collection frames, and the membrane modules in each collection frame are arranged in a pattern of 5 × 8, with a total of 120 membrane modules in the 3 collection frames.

[0021] This invention also provides a high-efficiency and energy-saving reciprocating integrated ultrafiltration method, based on the above-mentioned high-efficiency and energy-saving reciprocating integrated ultrafiltration equipment, comprising the following steps:

[0022] S1. Inlet and outlet water regulation: The wastewater to be treated is injected into the ultrafiltration membrane module tank, and the inlet water flow rate is adjusted to maintain the balance of inlet and outlet water;

[0023] S2. Stable and continuous processing: Turn on the drive component to make the drive motor drive the electric cylinder to reciprocate, thereby driving the slider to slide inside the slide rail, making the crossbeam and the entire membrane module collection frame reciprocate. The water output time of each membrane module collection frame is 9-10 minutes, and the rest time is 1-2 minutes. When one membrane module collection frame stops, the other membrane module collection frames continue to output water.

[0024] S3. Dynamic adjustment: Real-time monitoring of the outlet water pressure. If the outlet water pressure increases at a rate greater than 0.5 kPa / day, the frequency of the membrane module collector frame reciprocating motion is increased by 10-20%. If the outlet water pressure decreases at a rate greater than 0.5 kPa / day, the frequency of the membrane module collector frame reciprocating motion is decreased by 10-20%.

[0025] Furthermore, the reciprocating motion cycle of the membrane assembly frame is 2-3 seconds, and the reciprocating motion distance is 10-15 cm.

[0026] Explanation: By optimizing the cycle and distance of the reciprocating motion, the operating energy consumption is effectively reduced, while the high-quality ultrafiltration membrane material gives it a high filtration efficiency.

[0027] The beneficial effects of this invention are:

[0028] (1) The high-efficiency and energy-saving reciprocating integrated ultrafiltration equipment of the present invention uses the reciprocating motion of a low-power motor as an anti-fouling measure for the ultrafiltration membrane, which effectively reduces the operating energy consumption.

The equipment is compact in design, occupies a small area, and is easy to install and maintain. Users only need to follow the operation manual to complete the installation, debugging and operation of the equipment. In addition, the reciprocating design simplifies the internal mechanical structure and further reduces the difficulty of operation.

It can be used for small-scale domestic wastewater and kitchen leachate to large-scale industrial and municipal water treatment. It can be used for small household water purifiers to large-scale industrial water treatment equipment. At the same time, it can also be customized according to user needs to meet the water treatment needs of different occasions.

[0031] (4) The high-efficiency and energy-saving reciprocating integrated ultrafiltration equipment of the present invention increases the diversity of direction angles during reciprocating motion by setting up lifting components. It can realize single-direction reciprocating motion, synchronous lifting two-stage reciprocating motion, and continuous vibration reciprocating motion.

[0048] Example 2

[0049] The difference between this embodiment and Embodiment 1 is that:

[0050] The ultrafiltration membrane module housing 1 includes 4 membrane module collection racks 3 inside, and 8 butterfly valves 22 are provided on the circulation pipeline 2, with two corresponding to each membrane module collection rack 3.

[0051] Example 3

[0052] The difference between this embodiment and Embodiment 1 is that:

[0053] The ultrafiltration membrane module housing 1 includes 5 membrane module collection racks 3 inside, and 10 butterfly valves 22 are installed on the circulation pipeline 2, with two corresponding to each membrane module collection rack 3.

[0054] Example 4

[0055] The difference between this embodiment and Embodiment 1 is that:

[0056] The ultrafiltration membrane module housing 1 includes 6 membrane module collection racks 3 inside, and 12 butterfly valves 22 are provided on the circulation pipeline 2, with two corresponding to each membrane module collection rack 3.

[0057] Example 5

[0058] This embodiment provides a high-efficiency and energy-saving reciprocating integrated ultrafiltration method, based on a high-efficiency and energy-saving reciprocating integrated ultrafiltration equipment of Embodiment 1, including the following steps:

[0059] S1. Inlet and outlet water regulation: The wastewater to be treated is injected into the ultrafiltration membrane module tank 1. The liquid level is monitored by the liquid level gauge 15. The inlet water flow rate is regulated by the sludge return pump 54 and the inlet water pipe 17 to maintain the balance of inlet and outlet water. During operation under this balanced condition, the inlet water valve will close the inlet water when the liquid level is high and open the inlet water valve when the liquid level is low to ensure sufficient liquid level for continuous water production.

[0060] S2. Stable and continuous processing: The drive component 4 is turned on, and the drive motor 42 drives the electric cylinder 41 to reciprocate, thereby driving the slider 32 to slide inside the slide rail 12, so that the crossbeam 31 and the entire membrane module collector 3 reciprocate. The water output time of each membrane module collector 3 is 9.5 minutes and the rest time is 1.5 minutes. When one membrane module collector 3 stops, the other membrane module collector 3 continues to output water. Therefore, water production is continuous for 24 hours. The reciprocating motion cycle of the membrane module collector 3 is 2.5 seconds and the reciprocating motion distance is 12 cm.

[0061] S3. Dynamic Adjustment: The outlet water pressure is monitored in real time by the negative pressure sensor installed inside the ultrafiltration membrane module housing 1. If the outlet water pressure increases at a rate greater than 0.5 kPa / day, the frequency of the reciprocating motion of the membrane module collector 3 is increased by 10-20%. If the outlet water pressure decreases at a rate greater than 0.5 kPa / day, the frequency of the reciprocating motion of the membrane module collector 3 is decreased by 10-20%. This saves energy and allows the equipment to operate at low power, extending its lifespan. By adjusting the reciprocating motion frequency, the increase of the negative pressure in the outlet water is ensured to be within a suitable range.

[0062] In addition, the ultrafiltration membrane module housing 1 is also equipped with a pressure gauge, a permeate float flow meter, and a permeate turbidity meter to monitor the changes in values ​​in real time. During the gradual operation, if the turbidity value increases significantly in a short period of time, it is necessary to observe the working status of the sludge return pump 15, or appropriately increase the sludge return flow rate to accelerate the sludge return in the ultrafiltration membrane module housing 1 and avoid sludge deposition; conversely, the sludge return flow rate can be reduced to control the sludge concentration in the ultrafiltration membrane module housing 1 within a low range.

[0063] Example 6

[0064] The difference between this embodiment and Embodiment 1 is that:

[0065] S2. Stable and continuous processing: The drive component 4 is turned on, and the drive motor 42 drives the electric cylinder 41 to reciprocate, thereby driving the slider 32 to slide inside the slide rail 12, so that the crossbeam 31 and the entire membrane module collector 3 reciprocate. The water output time of each membrane module collector 3 is 9 minutes and the rest time is 1 minute. When one membrane module collector 3 stops, the other membrane module collector 3 continues to output water. Therefore, water production is continuous for 24 hours. The reciprocating motion cycle of the membrane module collector 3 is 2 seconds and the reciprocating motion distance is 10 cm.

[0066] Example 7

[0067] The difference between this embodiment and Embodiment 1 is that:

[0068] S2. Stable and continuous processing: The drive component 4 is turned on, so that the drive motor 42 drives the electric cylinder 41 to reciprocate, thereby driving the slider 32 to slide inside the slide rail 12, so that the crossbeam 31 and the entire membrane module collector 3 reciprocate. The water output time of each membrane module collector 3 is 10 minutes and the rest time is 2 minutes. When one membrane module collector 3 stops, the other membrane module collector 3 continues to output water. Therefore, water production is continuous for 24 hours. The reciprocating motion cycle of the membrane module collector 3 is 3 seconds and the reciprocating motion distance is 15 cm.

[0069] Example 8

[0070] The difference between this embodiment and Embodiment 1 is that:

[0071] S3. Dynamic adjustment: The outlet water pressure is monitored in real time by the negative pressure sensor installed inside the ultrafiltration membrane module housing 1. If the outlet water pressure increases at a rate greater than 0.5 kPa / day, the frequency of the reciprocating motion of the membrane module collector 3 is increased by 10-20%. If the outlet water pressure decreases at a rate greater than 0.5 kPa / day, the frequency of the reciprocating motion of the membrane module collector 3 is decreased by 10-20%.

[0072] Example 9

[0073] The difference between this embodiment and Embodiment 1 is that:

[0074] S3. Dynamic adjustment: The outlet water pressure is monitored in real time by the negative pressure sensor installed inside the ultrafiltration membrane module box 1. If the outlet water pressure increases at a rate greater than 0.5 kPa / day, the frequency of the reciprocating motion of the membrane module collector 3 is increased by 15%. If the outlet water pressure decreases at a rate greater than 0.5 kPa / day, the frequency of the reciprocating motion of the membrane module collector 3 is decreased by 15%.

[0075] Working principle:

[0076] The working principle of a high-efficiency and energy-saving reciprocating integrated ultrafiltration equipment of the present invention will be briefly explained below.

[0077] During wastewater treatment, the feed liquid is pretreated and then enters the ultrafiltration membrane module chamber 1. Under pressure, small molecules pass through the ultrafiltration membrane to become permeate, while large molecules are retained to form concentrate. The membrane module is backwashed and chemically cleaned regularly to maintain membrane performance and achieve efficient separation and purification.

[0078] The reciprocating motion of the membrane module frame 3 has three modes: unidirectional reciprocating motion, synchronous lifting two-stage reciprocating motion, and continuous vibration reciprocating motion.

[0079] Unidirectional reciprocating motion: At this time, the lifting component 6 is not set, or the lifting component 6 is also equipped with a lifting motor at the bottom, which drives the top of the limit block 62 to be below the bottom of the membrane assembly frame 3. At this time, the drive motor 42 is turned on, so that it drives each slider 32 to reciprocate through the electric cylinder 41, thereby driving each membrane assembly frame 3 to reciprocate synchronously through the crossbeam 31.

[0080] In the ultrafiltration process of the membrane module frame 3, the ultrafiltration membrane fibers inside the membrane module frame 3 play a core role. They can selectively permeate, allowing small molecules and water molecules in the liquid to be treated to pass through the membrane pores, while impurities larger than the membrane pore size, such as suspended particles, colloids, bacteria, viruses, and large organic molecules, are effectively retained.

[0081] Therefore, suction separation is completed by suction, purified permeate is formed inside the membrane, and concentrate is generated outside the membrane. The concentrate is periodically returned to the front end of the treatment liquid by sludge return pump 54 to ensure that the concentrate in the ultrafiltration membrane module box 1 is not too high, so as not to cause excessive fouling of the ultrafiltration membrane fibers, resulting in a surge in transmembrane pressure difference, which would affect permeate and cleaning and maintenance.

[0082] By connecting to the backwash pump 56 and the cleaning water tank 53, the control cabinet 51 programmatically controls the periodic backwashing after a fixed water production cycle. The entire system is intelligently controlled by the control cabinet 51 inside the equipment. With a fixed water production and backwashing cycle, and under the liquid level monitoring feedback of the level gauge 15, the system continuously feeds water into the ultrafiltration membrane module tank 1 and returns sludge, achieving automated, efficient, energy-saving, continuous, and stable water production.

[0083] Synchronous lifting and lowering two-stage reciprocating motion: At this time, the side of the limiting block 62 of the lifting component 6 corresponds to the position of the roller 33. At this time, the drive motor 42 is turned on, so that it drives each slider 32 to reciprocate through the electric cylinder 41. In turn, the crossbeam 31 drives each membrane component collection frame 3 to reciprocate synchronously. While the membrane component collection frame 3 moves forward, the roller 33 contacts the side of the limiting block 62, thereby achieving upward rolling and driving the membrane component collection frame 3 to move up. When it moves past the position of the slide plate 67, it then descends, realizing up and down floating. At the same time, the telescopic rod 34 extends and retracts to counteract the up and down movement.

[0084] Continuous vibration reciprocating motion: At this time, the rotating motor 61 is turned on, causing the lifting component 6 to rotate 90°, and the front of the limiting block 62 corresponds to the position of the roller 33. At this time, the drive motor 42 is turned on, causing it to drive each slider 32 to reciprocate through the electric cylinder 41. This, in turn, drives each membrane component assembly frame 3 to reciprocate synchronously through the crossbeam 31. While the membrane component assembly frame 3 moves forward, the roller 33 contacts the transition plate 65. After continuing to move, the magnetic suction plate 35 contacts the slide plate 67 and pushes the slide plate 67 to slide in the slide groove 66. At the same time, the roller 33 rolls on the upper surface of the limiting protrusion 64, thereby achieving high-frequency up and down vibration, driving the membrane component assembly frame 3 to perform high-frequency up and down vibration synchronously. The magnetic suction plate 35 always maintains magnetic connection with the slide plate 67 during the up and down movement. When it is necessary to reset, the magnetic suction plate 35 drives the slide plate 67 to reset, thus facilitating the next synchronous lifting and lowering two-stage reciprocating motion.
