DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0039] like Figure 1-Figure 2 As shown, a metal membrane filter separation device includes a shell component 1 for bearing and protection, a working chamber 1011 for fixing components used for liquid purification is opened in the shell component 1, a plurality of metal membrane filters 6 and agglomeration plates 12 are connected in the working chamber 1011, the agglomeration plate 12 is located on one side of the metal membrane filter 6, impurities dropped from the metal membrane filter 6 can fall to the bottom of the separation device through the agglomeration plate 12, a working component 10 is connected to the shell component 1, a cleaning component 11 is connected to the peripheral side of the metal membrane filter 6, the cleaning component 11 includes an ultrasonic vibration plate 1101 for removing impurities from the metal membrane filter 6, a cable port 1102 is connected to one side of the ultrasonic vibration plate 1101, and the cable port 1102 is connected to the field control component and the DCS control component outside the shell component 1.

[0040] The working component 10 includes a material outlet 1001 and a backwash port 1002, wherein the material outlet 1001 is located on the upper side of the shell component 1, wherein one side of the shell component 1 is also respectively connected with a liquid level meter 1003 and an interface meter 1004, wherein one end of the interface meter 1004 is connected with a material inlet (not marked in the figure), and the material inlet is connected with the inside of the shell component 1, and the end of the shell component 1 away from the material outlet 1001 is connected with a sewage outlet 13.

[0041] When it is necessary to clean the impurities inside the metal membrane filter 6, first open the bypass valve (or reduce the load), gradually close the inlet and outlet valves of the metal membrane filter 6, cut the process material into the cleaning component 11 to ensure that normal production is not affected, and then open the valves of the cooling water inlet and outlet of the equipment, and pass the circulating water to quickly cool the equipment to below the boiling point of the material, and then slightly open the backwash port 1002 on the top of the shell component 1, and at the same time, install the liquid level gauge 1003 on the top of the equipment. Under the premise of ensuring that the liquid level is not lower than the minimum liquid level (that is, ensuring that the filter element is always immersed in the liquid environment), as the pressure relief port is opened, the reading of the pressure gauge at the P port continues to decrease until the pressure is reduced to the optimal "0".

[0042] After the pressure relief operation, close the backwash port 1002 and start operating the control component. When the power indicator light is on and shows that the power is normal, turn the knobs of the control component to the "on" state one by one, and observe whether the operating indicator light of the ultrasonic vibration plate 1101 is normal, and then start the power cleaning operation.

[0043] After the ultrasonic cleaning operation begins, focus on observing the ammeter above each control button. Under normal circumstances, the ammeter reading should be 2~4A. If the current is too small, it means that the power wave device is not operating at the best state (when the pressure relief is insufficient, the ultrasonic wave will affect the operating state when it is running under pressure). The entire ultrasonic vibration plate 1101 cleaning lasts about 10~20 minutes per time.

[0044] At the same time, during the cleaning process, it is divided into two times. After the first cleaning, wait for 20 minutes, and then perform the second cleaning after the catalyst particles are settled. The specific details can be adjusted and determined according to the on-site cleaning situation.

[0045] After the ultrasonic cleaning is completed, the equipment is left to stand for more than 30 minutes so that the cleaned catalyst particles can gradually settle to the bottom of the equipment. Then, according to the accumulation of solid particles at the bottom, the drain port 13 is opened. After discharging part of the turbid liquid, the drain port 13 is closed, the inlet and outlet valves of the equipment are gradually opened, the bypass valve is closed, and the process material is cut into the equipment. At this time, the cleaning component 11 can be deactivated.

[0046] If the cleaning effect is weak during the cleaning process, you can add desalted water before cleaning to improve the cleaning effect. At the same time, when the metal membrane filter needs to be cleaned, there is no need for frequent disassembly and cleaning, low loss, closed and pollution-free, short cleaning cycle, and efficient and convenient regeneration effect. Example 2

[0047] like Figure 3-Figure 8 As shown, multiple metal membrane filters 6 are evenly distributed in a ring shape in the working chamber 1011, and one end of the multiple metal membrane filters 6 is connected to a circulation component 7, through which the filtered water is discharged, wherein the circulation component 7 is a sealed cavity, and one end of the multiple metal membrane filters 6 away from the circulation component 7 is connected to an air pressure component 8, and the air pressure value in the metal membrane filter 6 is regulated by the air pressure component 8 to ensure that the metal membrane filter 6 can effectively discharge waste water. At the same time, the change of the air pressure value of the air pressure component 8 is used to judge the purification rate in the metal membrane filter 6 to ensure that the metal membrane filter 6 is always in a high working state. The shell component 1 is connected to a flow component 4 for water intake and drainage, and the flow component 4 is connected to the circulation component 7.

[0048] The unfiltered liquid is injected into the metal membrane filter 6 through the circulation component 4, and the liquid is purified by the metal membrane filter 6 and then introduced into the circulation component 7. The circulation component 4 is then used to discharge the treated water in the circulation component 7. In this process, the air pressure component 8 can identify and determine the air pressure value in the metal membrane filter 6 to ensure that the liquid can maintain the purification rate.

[0049] In order to prevent the metal membrane filter 6 from being clogged and affecting the efficiency of liquid purification, a plurality of separation components 9 for cleaning the blockages in the metal membrane filter 6 are provided in the circulation component 7. The number of separation components 9 is the same as the number of metal membrane filters 6, that is, each metal membrane filter 6 corresponds to a separation component 9.

[0050] The separation component 9 includes a dirt storage box 901 for placing the cleaned debris, and a dirt storage cavity 9011 is opened in the dirt storage box 901, wherein the dirt storage cavity 9011 is connected with a boost pipe 906, and the end of the boost pipe 906 away from the dirt storage box 901 is connected with a ventilation plate 905, that is, the boost pipe 906 inflates the metal membrane filter 6 through the ventilation plate 905, thereby changing the air pressure value in the metal membrane filter 6, and a dirt collection pipe 904 is penetrated through the ventilation plate 905, and the length of the dirt collection pipe 904 can be adjusted telescopically, and during the normal operation of the metal membrane filter 6, the dirt collection pipe 904 is in a closed state to prevent unpurified liquid from entering the dirt storage cavity 9011 through the dirt collection pipe 904, but at the same time, in order to prevent impurities from Impurities accumulate in the purification pipe 604, and then the sewage collecting pipe 904 is controlled to open intermittently, so as to transfer the impurities in the purification pipe 604. The end of the sewage collecting pipe 904 away from the sewage storage box 901 is connected with a detection disk 903, and the end of the detection disk 903 away from the water inlet 605 is concave. After the metal membrane filter 6 separates the impurities, they can fall on the detection disk 903 and move to the sewage storage cavity 9011 through the sewage collecting pipe 904. The detection disk 903 can be used to identify the water flow rate in the metal membrane filter 6. When the metal membrane filter 6 is in a normal working state, the water flow rate detected by the detection disk 903 is in a normal working state. When the metal membrane filter 6 is blocked, the water flow rate passing through the detection disk 903 decreases.

[0051] The outer circumference of the boost pipe 906 is connected with a connecting portion 902, and the connecting portion 902 can be connected to the dirt storage box 901 to avoid leakage at the connection.

[0052] It should be noted that in order to prevent the liquid in the dirt storage chamber 9011 from accumulating and being unable to be discharged, and to prevent the impurities in the dirt storage chamber 9011 from entering the circulation component 7 again, activated carbon or other filter layers that meet the filtering standards are set in the box body of the dirt storage box 901, so that the water entering the dirt storage chamber 9011 can be discharged into the circulation component 7 through the filter layer. At the same time, in order to ensure that the water in the circulation component 7 does not enter the dirt storage chamber 9011, the liquid in the dirt storage chamber 9011 is only allowed to pass through the filter layer in one direction.

[0053] Furthermore, the metal membrane filter 6 includes a circulation tube 601, that is, the circulation tube 601 can allow purified water to pass through, and the two ends of the circulation tube 601 distributed along the length direction are respectively connected with a water outlet 602 and an exhaust port 603, wherein the exhaust port 603 is used to adjust the air pressure value in the metal membrane filter 6 to ensure that the water outlet 602 can normally discharge the filtered water, and a purification tube 604 is connected in the circulation tube 601, and a water inlet 605 is opened at one end of the purification tube 604, and the water inlet 605 and the water outlet 602 are located on the same side, and the diameter of the water inlet 605 is smaller than the diameter of the water outlet 602, the exhaust port 603 is connected to the air pressure component 8, and the water outlet 602 is connected to the circulation component 7, when the unfiltered water enters the purification tube 604 after passing through the water inlet 605, and the liquid can enter the circulation tube 601 through the purification tube 604, and be introduced into the circulation component 7 through the water outlet 602.

[0054] At the same time, in order to ensure that the separation component 9 can be in a normal working state, the diameter of the sewage collection pipe 904 is smaller than the diameter of the water inlet 605, and the diameter of the booster pipe 906 is smaller than the diameter of the water outlet 602, thereby ensuring that the water before and after purification can flow in the metal membrane filter 6.

[0055] The diameter of the detection disk 903 is larger than the caliber of the water inlet 605. On the one hand, the caliber of the detection disk 903 is used to identify the size of the water flow passing through the water inlet 605. On the other hand, when blockage occurs in the purification tube 604 and the liquid flow rate decreases, the detection disk 903 blocks the water inlet 605 to facilitate rapid adjustment of the air pressure in the metal membrane filter 6 through the ventilation plate 905. The diameter of the ventilation plate 905 is larger than the caliber of the water outlet 602, ensuring that while maintaining the normal passage of water, the gas can be prevented from being discharged through the water outlet 602 when the metal membrane filter 6 is pressurized.

[0056] It should be noted that the diameter of the detection disk 903 is smaller than the diameter of the purification tube 604 , and the diameter of the ventilation plate 905 is smaller than the diameter of the flow tube 601 .

[0057] When the purification rate of the purification tube 604 maintains a normal working state, the water flow through the water inlet 605 can drive the detection disk 903 to move, so that the detection disk 903 will not block the water inlet 605, and the water after passing through the purification tube 604 can be discharged through the water outlet 602. When the purification rate of the purification tube 604 is significantly reduced, the water at the water inlet 605 cannot lift the detection disk 903, which will cause the detection disk 903 to block the water inlet 605 under its own gravity, and control the closure of the sewage collection tube 904 to adjust the air pressure inside the metal membrane filter 6.

[0058] The materials and principles used in the filtering process of the metal membrane filter 6 are prior art and will not be elaborated herein.

[0059] In order to facilitate the identification of the use of the metal membrane filter 6, further, a detection plate 908 for identifying blockages is provided in the dirt storage chamber 9011, and a plurality of elastic rods 907 are connected to one end face of the detection plate 908. When impurities accumulate on the detection plate 908, the weight of the detection plate 908 will increase, which will increase the pressure on the elastic rod 907, thereby realizing the identification and detection of the content of impurities on the detection plate 908. The end of the elastic rod 907 away from the detection plate 908 is connected to the dirt collection pipe 904 to ensure that the impurities dropped on the detection plate 908 can be directly moved to the dirt storage chamber 9011, and the dirt storage box 901 is located in the circulation component 7, the detection disk 903 is located in the purification pipe 604, and the ventilation plate 905 is located in the circulation pipe 601. In order to effectively identify the impurities passing through the dirt collection pipe 904, the detection plate 905 is further 908 is arranged at one end of the dirt collecting pipe 904 located in the dirt storage chamber 9011. When the impurities pass through the dirt collecting pipe 904, they first fall on the detection plate 908, and the detection plate 908 is used to identify the weight of the impurities. At the same time, the filtration life of the metal membrane filter 6 is identified according to the weight detected by the detection plate 908. When the air pressure component 8 detects that the pressure value in the metal membrane filter 6 is abnormal, the separation component 9 is used to clean the inside of the metal membrane filter 6. When the cleaned impurities fall on the detection plate 908 through the dirt collecting pipe 904, the foreign matter on the detection plate 908 is identified. When the detection plate 908 detects that the weight of the impurities is small, it means that the metal membrane filter 6 is still in normal working condition. When the detection plate 908 detects that the weight of the impurities is large, it means that the working condition of the metal membrane filter 6 is reduced and needs to be repaired or replaced in time.

[0060] In order to facilitate the circulation of the liquid in the metal membrane filter 6, the circulation component 4 further includes a cluster tube 401, that is, it includes pipes used for water inlet and water outlet. The pipes on the cluster tube 401 are connected to the outside world respectively, and the cluster tube 401 is connected with multiple water inlet pipes 402 and water outlet pipes 403. The multiple water outlet pipes 403 are connected to the circulation component 7 at one end away from the cluster tube 401, and the water inlet pipe 402 passes through the circulation component 7 and is directly connected to the water inlet 605.

[0061] Furthermore, the shell assembly 1 includes a supporting shell 101, one end of which is connected to a base 102 for stabilizing the device, a maintenance opening 103 for people to enter and exit is opened on the supporting shell 101, and a maintenance plate 5 for people to climb is connected to the supporting shell 101, and the maintenance plate 5 is located on the side of the maintenance opening 103 close to the base 102, ensuring that the components in the working chamber 1011 can be repaired and protected.

[0062] In order to facilitate the identification and adjustment of the working air pressure of the metal membrane filter 6, further, an air pressure detection gauge 3 and an air outlet 2 are respectively connected to the side of the supporting shell 101 away from the base 102, one end of the air pressure detection gauge 3 is connected to the air pressure component 8, and one end of the air outlet 2 passes through the supporting shell 101 and is connected to the air pressure component 8. The air pressure value of the metal membrane filter 6 is identified by the air pressure detection gauge 3, and the air pressure inside it is regulated by using the air outlet 2.

[0063] During operation, the water to be purified is passed into the cluster tube 401 and introduced into the water inlet 605 through the water inlet pipe 402, so that the liquid enters the purification pipe 604 for filtration, and the filtered water enters the circulation pipe 601, and then is discharged into the circulation component 7 through the water outlet 602, and the purified water in the circulation component 7 is discharged using the water outlet pipe 403.

[0064] When the purification rate of the purification tube 604 maintains a normal working state, the water flow through the water inlet 605 can drive the detection plate 903 to move, so that the water inlet 605 is opened, so that the detection plate 903 does not block the water inlet 605, ensuring that the air intake rate in the water inlet 605 is stable, and the water after passing through the purification tube 604 can be discharged through the water outlet 602. When the purification rate of the purification tube 604 decreases significantly, the water in the water inlet 605 cannot lift the detection plate 903, which will cause the detection plate 903 to block the water inlet 605 under its own gravity, thereby closing the sewage collection pipe 904 and the exhaust port 603, The internal space of the metal membrane filter 6 forms a relatively closed space, so as to adjust the air pressure inside the metal membrane filter 6, and then control the boost pipe 906 to pressurize the flow pipe 601 through the ventilation plate 905, so as to increase the pressure value in the flow pipe 601, and because there are air holes on the purification pipe 604, when the air pressure value in the flow pipe 601 increases, the air pressure value in the purification pipe 604 will be caused to rise slowly and synchronously, and the air pressure value in the purification pipe 604 is always less than the air pressure value in the flow pipe 601, and in the process of pressurization, the impurities that are not stuck on the purification pipe 604 are removed and fall onto the detection plate 903 to wait for processing.

[0065] When the purification tube 604 is in a normal working state, the air pressure detection meter 3 maintains the normal detection pressure unchanged. When the purification tube 604 is blocked and the purification efficiency is reduced, the pressure detected by the air pressure detection meter 3 will increase.

[0066] When the air pressure detection meter 3 recognizes that the metal membrane filter 6 has a significant increase, the sewage collection pipe 904 is opened, causing the pressure value in the purification pipe 604 to decrease instantly, causing the pressure in the circulation pipe 601 to quickly impact the pipe wall of the purification pipe 604, thereby achieving the purpose of separating impurities.

[0067] The impurities separated by the purification tube 604 fall onto the detection plate 908 through the sewage collecting tube 904. After passing through the sewage collecting tube 904, the impurities first fall onto the detection plate 908, and the detection plate 908 is used to identify the weight of the impurities. At the same time, the filtration life of the metal membrane filter 6 is identified according to the weight detected by the detection plate 908. When the air pressure component 8 detects that the pressure value in the metal membrane filter 6 is abnormal, the separation component 9 is used to clean the metal membrane filter 6. When the cleaned impurities fall onto the detection plate 908 through the sewage collecting tube 904, the foreign matter on the detection plate 908 is identified. When the detection board 908 detects that the weight of the impurities is small, it means that the metal membrane filter 6 is still in normal working condition. When the detection board 908 detects that the weight of the impurities is large, it means that the working condition of the metal membrane filter 6 is reduced and needs to be repaired or replaced in time to ensure the working efficiency of the metal membrane filter 6.

[0068] The present invention also includes a separation method, which is performed using the separation device described in Example 1 and specifically includes the following steps:

[0069] Step 1: When the purification pipe 604 is clogged, the air pressure value of the air pressure detection meter 3 will increase, and the detection plate 903 will close the water inlet 605, the ventilation plate 905 will close the water outlet 602, and the exhaust port 603 and the sewage collection pipe 904 will be closed;

[0070] Step 2: Use the booster pipe 906 and the ventilation plate 905 to inflate the metal membrane filter 6, so that the pressure in the flow pipe 601 moves to the purification pipe 604;

[0071] Step 3: When the air pressure detection meter 3 recognizes that the pressure value in the metal membrane filter 6 reaches the preset value, the sewage collecting pipe 904 is controlled to open, so that the pressure in the purification pipe 604 is quickly released, and the gas in the flow pipe 601 is driven to move quickly into the purification pipe 604;

[0072] Step 4: After using air pressure to remove impurities from the purification tube 604, the impurities are moved to the detection plate 908 through the waste collection tube 904, and the quality on the detection plate 908 is identified using the elastic rod 907;

[0073] Step 5: The liquid entering the sewage collecting pipe 904 is purified by the sewage storage tank 901 and then discharged into the circulation component 7.
