A descaling device for an ion membrane electrochemical water treatment apparatus

Abstract

This utility model relates to a descaling device for an ion-exchange membrane electrochemical water treatment system. This utility model effectively solves the problems of inconvenient operation and inability to guarantee effective removal of impurities in some ion-exchange membrane descaling devices. The descaling device of this ion-exchange membrane electrochemical water treatment system uses a first driving component to move the descaling mechanism and vibration mechanism to corresponding positions on different ion-exchange membranes. A second driving component moves the descaling mechanism along the outer side of the ion-exchange membrane, allowing the descaling mechanism to rinse both sides of the ion-exchange membrane while simultaneously removing the washed-off scale and impurities, preventing impurities from re-adsorbing onto the ion-exchange membrane. The vibration mechanism provides high-frequency vibration to the ion-exchange membrane, dislodging impurities from the membrane and allowing them to be removed by the descaling mechanism. This effectively improves descaling efficiency and thoroughly cleans both sides of the ion-exchange membrane, resulting in better descaling effects. Furthermore, it requires no manual operation, has higher descaling efficiency, and is more convenient for descaling ion-exchange membranes in water treatment equipment.

Description

Technical Field

[0001] This utility model belongs to the technical field of ion membrane cleaning devices, specifically relating to a descaling device for an ion membrane electrochemical water treatment system. Background Technology

[0002] Electrochemical water treatment technology refers to a process in which, under the influence of an external electric field and within specific electrochemical water treatment equipment, a series of designed chemical reactions, electrochemical processes, or physical processes generate a large number of free radicals. These free radicals then utilize their strong oxidizing properties to degrade pollutants in wastewater. As a clean treatment process, electrochemical technology has unparalleled advantages compared to other water treatment technologies and is an important method for addressing the negative problems associated with the use of chemical agents in industrial water treatment. Electrochemical circulating water quality stabilization technology exhibits excellent corrosion inhibition, scale inhibition, and bactericidal and algae-killing effects. Circulating water using this technology does not require the addition of any chemical agents, and the forced discharge of wastewater is minimal, saving on chemical and makeup water costs while also providing significant energy savings, emission reduction, and environmental protection benefits.

[0003] However, during long-term operation, the surface of the ion exchange membrane is prone to clogging due to pollutant deposition, scaling, or microbial growth, leading to decreased treatment efficiency and increased energy consumption. Most existing ion exchange membrane descaling devices use disassembly and cleaning or chemical soaking methods, which are inconvenient to operate and cannot guarantee the effective removal of impurities. They are not conducive to fully removing scale and impurities on both sides of the ion exchange membrane, affecting the filtration effect of the ion exchange membrane and hindering the efficient operation of electrochemical water treatment equipment.

[0015] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The embodiments are described in detail below.

[0016] This embodiment provides a descaling device for an ion-exchange membrane electrochemical water treatment system, as shown in the attached diagram. Figure 1As shown, the device includes a horizontally moving plate 1 and a disassembly plate 2. The lower surface of the horizontally moving plate 1 is provided with a first driving assembly 3, which can drive its horizontal movement. The first driving assembly 3 can be horizontally installed at the top of the water treatment equipment. The first driving assembly 3 can drive the horizontally moving plate 1 to move horizontally back and forth at the top of the water treatment equipment, and the direction of movement of the horizontally moving plate 1 corresponds to the installation state of the ion membrane. When not descaling the ion membrane, the first driving assembly 3 drives the horizontally moving plate 1 to one side of the water treatment equipment without affecting its internal structure. The upper surface of the horizontally moving plate 1 is provided with a second driving assembly 4, and the movable end of the second driving assembly 4 is connected to a horizontally moving frame 5. The second driving assembly 4 can drive the horizontally moving frame 5 to move horizontally back and forth on the horizontally moving plate 1, thereby facilitating the adjustment of the disassembly plate 2 below. The overall structure is positioned as follows: The disassembly plate 2 is fixedly connected to the bottom of the transverse moving frame 5, and a descaling mechanism 6 for efficient rinsing of the ion membrane is provided on one side of its upper surface. The descaling mechanism 6 corresponds to both sides of the ion membrane, and is driven by the second drive component 4 to move along both sides of the ion membrane, which can fully rinse both sides of the ion membrane. The height of the descaling mechanism 6 can be dynamically adjusted to facilitate full rinsing of different height parts of the ion membrane, improve the descaling effect, and clean the ion membrane more thoroughly. On the other side of the upper surface of the disassembly plate 2, a vibration mechanism 7 for high-frequency vibration of the ion membrane is provided. The vibration mechanism 7 can contact the top of the ion membrane and vibrate the ion membrane at high frequency, thereby shaking off the scale and impurities on both sides of the ion membrane, making it easier for the descaling mechanism 6 to rinse and remove the impurities. Among them, such as Figure 4 As shown, the descaling mechanism 6 includes a first electric push rod 601, a vertical plate 602, a flushing pipe 603, and a negative pressure suction pipe 604. The vertical plate 602 is fixedly connected to the movable end of the first electric push rod 601, and the flushing pipe 603 and the negative pressure suction pipe 604 are both vertically fixedly installed on the side of the vertical plate 602. The movable end of the first electric push rod 601 passes through the lower surface of the disassembly plate 2. The bottom ends of the two vertical plates 602 are fixedly connected to the movable end of the first electric push rod 601, and the two vertical plates 602 can be respectively set on both sides of the ion membrane. The first electric push rod 601 drives the two sides... When the vertical plate 602 is raised to its highest position, the second drive assembly 4 can drive the descaling mechanism 6 and the vibration mechanism 7 to move laterally within the water treatment equipment, making it easy to align the descaling mechanism 6 and the vibration mechanism 7 with different ion membranes vertically. When it is necessary to descale the corresponding ion membrane, the first electric push rod 601 can drive the vertical plate 602 to descend, so that the flushing pipes 603 and the negative pressure suction pipes 604 on both sides are fully aligned with the sides of the ion membrane. The flushing pipes 603 and the negative pressure suction pipes 604 can flush and descale both sides of the ion membrane and suck out the scale and impurities that have been flushed away.

[0017] In one alternative implementation, such as Figure 4As shown, there are two of each of the following components: the first electric push rod 601, the vertical plate 602, the rinsing pipe 603, and the negative pressure suction pipe 604. These components are symmetrically arranged about the vertical centerline of the disassembly plate 2. The fixed ends of both first electric push rods 601 are vertically fixed to the upper surface of the disassembly plate 2. Rinsing heads are vertically and equidistantly connected to the side of the rinsing pipe 603, allowing water to be sprayed out under high pressure from the rinsing heads, thus rinsing the side of the ion exchange membrane. Suction pipe heads are vertically and equidistantly connected to the side of the negative pressure suction pipe 604, allowing the suction pipe heads to rinse the rinsing head. The water around the membrane is drawn away to quickly remove the scale and impurities that have been rinsed off, preventing them from being re-adsorbed onto the ion exchange membrane and affecting the descaling effect. The rinsing head and the suction pipe head are both horizontally inserted through the side of the corresponding vertical plate 602. The rinsing head and the suction pipe head on both sides are symmetrically arranged. The first electric push rod 601 can drive the vertical plate 602 to move up and down, making it easy to adjust the rinsing pipe 603 and the negative pressure suction pipe 604 to the corresponding positions according to the height of the ion exchange membrane. At the same time, when cleaning the ion exchange membrane, the first electric push rod 601 can drive the vertical plate 602 to move up and down in a small range, which can fully rinse and descale all parts of the ion exchange membrane, making the cleaning more thorough.

[0018] In one optional embodiment, the vibration mechanism 7 includes a second electric push rod 701, a connecting plate 702, a spring 703, a bracket 704, a vibration motor 705, and a vibration wheel 706. The fixed end of the second electric push rod 701 is fixedly installed on the upper surface of the disassembly plate 2 on the side away from the descaling mechanism 6. The connecting plate 702 is fixedly connected to the movable end of the second electric push rod 701, and springs 703 are fixedly connected to the four corners of its lower surface. The springs 703 can buffer the vibration transmitted to the connecting plate 702 and the second electric push rod 701 when the vibration motor 705 vibrates. The vibration bracket 704 is fixedly connected to the bottom end of the spring 703 and the vibration motor 705 is fixedly installed inside it. Vibration wheels 706 are rotatably connected to both sides of the bottom end of the bracket 704. The operation of the vibration motor 705 can cause the vibration wheels 706 on both sides of the bottom to generate high-frequency vibration. The second electric push rod 701 can adjust the height of the vibration wheels 706, so that the vibration wheels 706 on both sides can be pressed tightly against the top of the ion membrane. This allows the vibration wheels 706 to conduct high-frequency vibration to the ion membrane, shaking off the scale and impurities adsorbed on the ion membrane, making it easier to remove scale and impurities.

[0019] In one optional embodiment, the first drive assembly 3 includes a first motor 301, a first lead screw 302, and a guide rod 303. The first lead screw 302 is connected to the output end of the first motor 301 via a spline. The guide rod 303 is parallel to the first lead screw 302 and passes through both sides of the lower surface of the horizontal moving plate 1. The first lead screw 302 is connected to the horizontal moving plate 1 via a threaded transmission. The first motor 301 can be fixedly installed outside the water treatment equipment, while the first lead screw 302 and the guide rod 303 can pass through the top of the inside of the water treatment equipment. The first motor 301 drives the first lead screw 302 to rotate, which can drive the horizontal moving plate 1 to move laterally back and forth along the direction of the guide rod 303. This allows the descaling mechanism 6 and the vibration mechanism 7 to correspond to different parts of the side of the ion membrane, so that the descaling mechanism 6 can fully descale both sides of the ion membrane.

[0020] In one optional embodiment, the second drive assembly 4 includes a second motor 401 and a second lead screw 402. The second lead screw 402 is splined to the output end of the second motor 401 and rotatably connected to the upper surface of the horizontal moving plate 1. The transverse moving frame 5 is threaded to the outside of the second lead screw 402 and passes through the middle of the horizontal moving plate 1. The transverse moving frame 5 can only move laterally back and forth along the direction of the horizontal moving plate 1. The second motor 401 drives the second lead screw 402 to rotate, which can drive the transverse moving frame 5 to move back and forth along the direction of the second lead screw 402. This facilitates the adjustment of the transverse position of the lower descaling mechanism 6 and the vibration mechanism 7, so that the descaling mechanism 6 and the vibration mechanism 7 can correspond to the ion membranes in different parts, which is convenient for descaling different ion membranes.

[0021] In one optional embodiment, the inlet ends of the two flushing pipes 603 are interconnected and connected to an external water supply pipe, and the top ends of the two negative pressure suction pipes 604 are interconnected and connected to an external suction pipe. The external water supply pipe supplies water into the flushing pipes 603 on both sides and sprays it out from the flushing heads on both sides, which can flush both sides of the ion membrane. Under the suction of the external suction pipe, the negative pressure suction pipes 604 on both sides can draw the water from the flushing area outward, thereby directly drawing out the scale and impurities washed off by the flushing heads, avoiding re-adsorption onto the ion membrane and affecting the descaling effect.

[0022] The first motor 301, the second motor 401, the first electric push rod 601, the second electric push rod 701, and the vibration motor 705 are all connected to an external control unit and are electrically connected to an external circuit via wires.

[0023] In summary, the descaling device of this ion-exchange membrane electrochemical water treatment equipment operates as follows: 1. When it is necessary to descale the ion membrane, keep the water in the water treatment equipment still, pause the water treatment process, and start the first drive assembly 3. The first motor 301 drives the first lead screw 302 to rotate, which drives the horizontal moving plate 1 to move along the direction of the guide rod 303. Position the horizontal moving plate 1 directly above the selected ion membrane unit. Then, the second motor 401 drives the second lead screw 402 to rotate, which drives the transverse moving frame 5 and the disassembly plate 2 at its bottom to make transverse fine adjustments, so that the descaling mechanism 6 and the vibration mechanism 7 are precisely aligned with the target ion membrane directly above it. 2. Activate the second electric push rod 701 to push the connecting plate 702 downward, and use the spring 703 and bracket 704 to press the two vibrating wheels 706 at the bottom end smoothly against the edge of the top of the target ion membrane or the designated vibration part; at the same time, activate the two first electric push rods 601 to push the vertical plate 602 downward, which will drive the flushing pipe 603 and the negative pressure suction pipe 604 installed on its side to descend, and adjust the flushing head on the flushing pipe 603 and the suction pipe head on the negative pressure suction pipe 604 to the position corresponding to the side of the ion membrane; 3. Start the vibration motor 705. The high-frequency vibration generated by the vibration motor 705 is transmitted to the ion membrane through the bracket 704 and the vibration wheel 706, which loosens and removes the scale and impurities attached to both sides of the ion membrane. Turn on the external water supply. The water flows into the interconnected flushing pipe 603 and is sprayed out at high pressure from the vertically arranged flushing heads to flush both sides of the ion membrane. At the same time, turn on the external negative pressure suction pipe. The scale, impurities and sewage washed off are quickly sucked away through the interconnected negative pressure suction pipe 604 and the suction head to prevent them from re-adhering to the membrane surface. 4. While continuously rinsing and adsorbing, the first electric push rod 601 is activated to perform a slow and continuous up-and-down reciprocating motion, driving the vertical plate 602 and all the rinsing heads and suction pipe heads on it to move along the height direction of the ion membrane, ensuring that the entire side of the ion membrane is thoroughly rinsed and impurities are sucked up without dead angles; at the same time, the second drive component 4 can drive the descaling mechanism 6 and the vibration mechanism 7 below to move slowly along the length direction of the ion membrane, so as to clean the entire ion membrane more thoroughly.

[0024] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
