Description

Technical Field

[0001] This invention relates to the field of isopropanol VOC treatment technology, specifically to an electronic-grade isopropanol VOC environmentally friendly circulating washing system and method. Background Technology

[0002] In the electronics field, electronic-grade isopropanol is widely used due to its high purity, low impurity content, and high solubility. However, its extensive use inevitably generates a large amount of electronic-grade isopropanol waste liquid. This waste liquid contains high levels of electronic-grade isopropanol, which is volatile. If it is directly discharged into the atmosphere without treatment, it will cause environmental pollution.

[0003] The existing methods for treating electronic-grade isopropanol waste liquid mostly involve storing the waste liquid in a wastewater tank and covering it with a sealed cover, while periodically treating the isopropanol vapor generated inside the sealed cover.

[0004] In the treatment process, washing towers are mostly used to wash isopropanol. Specifically, alkaline solutions are used to absorb isopropanol to achieve the goal of green emissions. During the washing process, isopropanol is mainly absorbed by spraying. However, the absorption of isopropanol by alkaline solutions is not completed instantaneously and requires a certain amount of time. When isopropanol vapor enters the washing tower, it maintains a constant flow state, resulting in a short reaction time with the alkaline solution. Therefore, although the isopropanol content in the vapor can be reduced during washing, it cannot be completely eliminated. Summary of the Invention

[0005] The purpose of this invention is to provide an electronic-grade isopropanol VOC-based environmentally friendly circulating washing system and method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An electronic-grade isopropanol VOC-free circulating washing system includes:

[0008] A washing tank, wherein two sets of air supply ends are symmetrically arranged on the side of the washing tank;

[0009] Multiple sets of inclined plates are rotatably installed inside the washing tank, and the multiple sets of inclined plates are staggered along the horizontal direction in space.

[0010] A drive assembly is connected to the tilting plate group, which can drive the tilting plate group to move, so that the tilting plate group has two symmetrical deflection states.

[0011] The pump assembly is connected to the gas delivery end and is used to pump electronic grade isopropanol VOC into the water washing tank. The pump assembly is provided with a sealing element. The sealing element can be switched in position to allow electronic grade isopropanol VOC to be pumped alternately toward the two sets of gas delivery ends.

[0012] A trigger component is connected to the drive component and the sealing component. The trigger component can switch the position of the sealing component when the tilting plate group has completed the deflection action.

[0013] As a further aspect of the present invention: the inclined plate assembly includes a deflector plate rotatably installed inside the washing tank, the interior of the deflector plate is a hollow structure, and telescopic plates are slidably and sealed at both ends of the deflector plate;

[0014] The inclined plate assembly also includes a guide structure connecting the telescopic plate and the washing tank. When the deflection plate performs a deflection action, the telescopic plate can perform a telescopic action relative to the deflection plate.

[0015] As a further embodiment of the present invention: the guide structure includes a first convex shaft connected to the side of the telescopic plate, the first convex shaft passing through a through slot opened on the side of the deflection plate and extending to the outside of the deflection plate;

[0016] The guiding structure also includes a guide plate connected to the inner wall of the washing tank, and the guide plate is provided with a V-shaped groove that is slidably connected to the first convex shaft.

[0017] As a further embodiment of the present invention: the driving assembly includes a connecting rod connected to the rotating shaft of the deflection plate, a driving rod rotatably connected to one end of the connecting rod away from the rotating shaft of the deflection plate, a connecting member slidably mounted on the driving rod, and the connecting member being connected to an electric telescopic rod fixedly mounted on the side wall of the washing tank.

[0018] As a further embodiment of the present invention: an insertion tube is provided inside the washing tank, and multiple water inlets are provided on both sides of the insertion tube. The insertion tube is connected to a liquid pump located outside the washing tank, and the outlet of the liquid pump is connected to a spray pipe located inside the washing tank.

[0019] As a further embodiment of the present invention: the pumping assembly includes a high-pressure air pump installed on the side of the washing tank, the outlet of the high-pressure air pump is connected to a switching pipe, the two sides of the switching pipe are connected to two sets of air delivery ends, and the inner wall of the switching pipe is slidably connected to the sealing member. When the sealing member moves from one side of the inner wall of the switching pipe to the other side, the pumping direction of electronic grade isopropanol VOC will change.

[0020] As a further embodiment of the present invention: the triggering component includes:

[0021] A follower frame is connected to the actuating end of the electric telescopic rod, and a horizontal slot is provided on the follower frame;

[0022] A transverse sliding frame is slidably disposed through the switching tube body. The transverse sliding frame is connected to the sealing component, and a connecting groove is provided along the length of the transverse sliding frame.

[0023] A trigger structure is provided, which connects the washing tank and the connecting groove. The trigger structure is provided with a second convex shaft that can slide in the horizontal groove. When the follower frame moves to the end of its stroke, the trigger structure can actively drive the sealing component to perform a position switching action.

[0024] As a further embodiment of the present invention: the triggering structure includes a vertical plate connected to the second convex shaft, and a sliding connecting part is installed on the vertical plate, the sliding connecting part being slidably connected to the connecting groove;

[0025] The upright plate is also provided with a sliding groove along its length, and a slider is slidably installed in the sliding groove. The slider is connected to the side wall of the sliding groove by a cylindrical spring, and the slider is rotatably installed with an abutment shaft facing the side of the washing tank.

[0026] The triggering structure also includes an abutment member connected to the washing tank, the abutment member being adapted to the abutment shaft.

[0027] As a further embodiment of the present invention: the abutting member is provided with two sets of inclined surfaces on the side facing the abutting shaft, and an upwardly protruding part is formed at the connection of the two sets of inclined surfaces. When the abutting shaft moves along one of the sets of inclined surfaces toward the protruding part, the cylindrical spring can be stretched.

[0028] A method of using the electronic-grade isopropanol VOC-friendly circulating washing system as described above includes the following steps:

[0029] Step 1: Connect the sealing cover on the electronic grade isopropanol VOC wastewater tank to the pump assembly via pipeline;

[0030] Step 2: Start the air pumping unit, which can draw the gas generated in the electronic grade isopropanol VOC wastewater tank into the water washing tank.

[0031] Step 3: The gas entering the washing tank has a high velocity and can move along multiple sets of inclined plates, and is absorbed by the alkaline solution in the washing tank;

[0032] Step 4: The gas slows down until it moves above the surface of the alkaline solution under the action of buoyancy, thus completing the water washing.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] By using an inclined plate assembly, when gas acts on the assembly, it moves downwards under the guidance of the assembly, thus suppressing the upward movement of the gas due to buoyancy. This increases the residence time of the gas in the alkaline solution. When the horizontal velocity of the gas drops to zero, it can also move in the opposite direction along the inclined plate assembly, allowing for a horizontal reverse movement process. During this process, the residence time of the gas in the alkaline solution is further increased, giving the alkaline solution a longer time to absorb electronic-grade isopropanol VOCs. This ensures the absorption effect of electronic-grade isopropanol VOCs, reduces the content of electronic-grade isopropanol VOCs escaping from the alkaline solution, and achieves the effect of green emissions.

[0035] By using the installed inlet pipe, liquid pump, and spray pipe, not only can the atomized alkaline solution and the alkaline solution gas be fully contacted, thus further treating any residual electronic-grade isopropanol VOCs in the gas and reducing the content of electronic-grade isopropanol VOCs in the exhaust gas, but the alkaline solution also tends to move towards the center of the washing tank. Under this tendency, the alkaline solution moves from the gas supply end towards the inlet pipe, and the movement of the alkaline solution actively drives the movement of the gas entering the washing tank from the gas supply end. This results in a longer lateral displacement distance of the gas in the washing tank, further increasing the residence time of the gas in the washing tank and improving the treatment effect.

[0036] By adjusting the position of the sealing component through the triggering and pumping components, the gas containing electronic-grade isopropanol VOCs can be alternately introduced into the washing tank from both sets of gas delivery ends. This ensures that the alkaline solution on both sides of the washing tank is relatively uniformly saturated, guaranteeing the absorption effect of electronic-grade isopropanol VOCs and making full use of the alkaline solution. At the same time, by rapidly switching the position of the sealing component, the overlap time between the sealing component and the gas inlet is shortened, effectively preventing the compressed gas from entering the washing tank from both sets of gas delivery ends when the sealing component overlaps with the gas inlet, which would cause a drop in injection pressure and result in the gas having too short a lateral movement distance in the washing tank, thus preventing the electronic-grade isopropanol VOCs from being completely absorbed.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0049] Please see Figures 1-9 In this embodiment of the invention, an electronic-grade isopropanol VOC-environmentally friendly circulating washing system includes: a washing tank 1, multiple sets of inclined plates, a drive assembly, a pump assembly, and a trigger assembly.

[0050] The side of the washing tank 1 is symmetrically provided with two sets of air supply ends 12. The washing tank 1 is filled with an alkaline solution. The alkaline solution can absorb the isopropanol VOC in the gas generated in the electronic grade isopropanol VOC wastewater pool, so as to ensure that the gas discharged does not contain isopropanol VOC, thereby achieving the purpose of green emission.

[0051] Multiple sets of inclined plates are rotatably installed inside the washing tank 1. The alkaline solution in the washing tank 1 should completely immerse the inclined plates. The multiple sets of inclined plates are staggered along the horizontal direction in space, and the rotation axes of the multiple sets of inclined plates are on the same horizontal plane.

[0052] In the initial state, the multiple sets of inclined plates are parallel and tilted (see...). Figure 5 At this point, the gas containing electronic-grade isopropanol VOC, pressurized by the pump assembly, enters the washing tank 1 and moves rapidly horizontally. Specifically, taking the upper end of the inclined plate assembly as end a and the lower end as end b, the gas moves from end a towards end b. Simultaneously, during this horizontal movement, the gas is also subject to buoyancy and will move upwards. This allows the gas to move downwards under the guidance of the inclined plate assembly, thus suppressing the upward tendency of the gas due to buoyancy, thereby increasing the residence time of the gas in the alkaline solution. Furthermore, under the influence of the alkaline solution... Under these conditions, the horizontal velocity of the gas will decrease, and when the horizontal velocity of the gas drops to zero, the gas can still move in the opposite direction along the inclined plate group. That is, at this time, the gas can move from end b to end a, so that the gas can have a horizontal reverse movement process. During this process, the residence time of the gas in the alkaline solution is further increased, so that the alkaline solution has a longer time to absorb electronic grade isopropanol VOCs, thus ensuring the absorption effect of electronic grade isopropanol VOCs, reducing the content of electronic grade isopropanol VOCs escaping from the alkaline solution, and achieving the effect of green emission.

[0053] Please see Figures 3-5The inclined plate assembly includes a deflection plate 2 rotatably installed inside the washing tank 1. The interior of the deflection plate 2 is hollow, and telescopic plates 3 are slidably and sealed at both ends of the deflection plate 2.

[0054] The inclined plate assembly also includes a guide structure connecting the telescopic plate 3 and the washing tank 1. When the deflection plate 2 performs a deflection action, the telescopic plate 3 can perform a telescopic action relative to the deflection plate 2. The guide structure includes a first convex shaft 301 connected to the side of the telescopic plate 3. The first convex shaft 301 passes through the through groove 201 opened on the side of the deflection plate 2 and extends to the outside of the deflection plate 2.

[0055] The guiding structure also includes a guide plate 4 connected to the inner wall of the washing tank 1. The guide plate 4 is provided with a V-shaped groove 401 that is slidably connected to the first convex shaft 301. Specifically, the V-shaped groove 401 is horizontally arranged, that is, the V-shaped opening of the V-shaped groove 401 faces the horizontal direction.

[0056] In the initial state, the deflector plate 2 is tilted. At this time, the first convex shaft 301 on one end of the telescopic plate 3 of the deflector plate 2 is at the end of one end of the V-groove 401 that it mates with, while the first convex shaft 301 on the other set of telescopic plates 3 is at the end of the other end of the V-groove 401 that it mates with. This state ensures that the deflector plate 2 can form its maximum length with the two sets of telescopic plates 3, allowing adjacent sets of tilting plates to have an overlapping area along the horizontal plane. This ensures that when the gas moves laterally, the tilting plates can suppress upward movement under their guidance. When the drive assembly actuates to switch the tilting plates to their tilted state, the deflector plate 2 will actively deflect, and the two sets of telescopic plates 3 connected to it will perform circular motion. The corresponding first convex shaft 301 will move along the V-groove 401, so that during the deflection of the deflection plate 2, the telescopic plate 3 can move toward the inside of the deflection plate 2, so that when the two adjacent sets of deflection plates 2 are deflected to the horizontal position, the telescopic plates 3 at the opposite ends of the two will not interfere with each other. At the same time, when the deflection plate 2 completes the reverse deflection, the corresponding first convex shaft 301 will move to the other end of the V-groove 401, so that the telescopic plate 3 can extend outward toward the deflection plate 2 to the maximum extent, thereby maintaining the state in which the two adjacent sets of inclined plates have overlapping areas along the horizontal plane, so that when the gas containing electronic grade isopropanol VOC is ejected through another set of gas delivery ends 12, the gas can also have a longer residence time in the alkaline solution.

[0057] Please see Figures 1-4The drive assembly is connected to the deflection plate 2. The drive assembly can drive the tilting plate group to move, so that the tilting plate group has two symmetrical deflection states. The drive assembly includes a connecting rod 5 connected to the rotation axis of the deflection plate 2. A drive rod 6 is rotatably connected to one end of the connecting rod 5 away from the rotation axis of the deflection plate 2. A connecting piece 7 is slidably installed on the drive rod 6. The connecting piece 7 is connected to an electric telescopic rod 8 fixedly installed on the side wall of the washing tank 1.

[0058] Specifically, for two adjacent sets of deflecting plates 2, the distance between the corresponding connecting rod 5 and the drive rod 6 is equal to the distance between the rotation axes of the two sets of deflecting plates 2. This makes the line connecting the two sets of connecting rods 5, the drive rod 6, and the rotation axes of the two sets of deflecting plates 2 form a parallelogram. Thus, when the drive rod 6 moves, it can synchronously drive multiple sets of deflecting plates 2 to deflect. This allows multiple sets of inclined plates to maintain a parallel state during both stationary and deflection processes, thereby improving the guiding effect on the gas and preventing excessive resistance to gas movement caused by an excessively large tilt angle of a certain set of inclined plates, which would force the gas to stop moving and rise under the action of buoyancy.

[0059] It should be noted that the end of the drive rod 6 has a strip-shaped hollow groove, and the connecting piece 7 passes through the strip-shaped hollow groove. Multiple sets of rollers are rotatably installed on both sides of the connecting piece 7. The rollers are in a rolling contact with both sides of the drive rod 6. The significance of this arrangement is that when the electric telescopic rod 8 drives the drive rod 6 to move, the connecting rod 5 performs a circular motion, which supports the drive rod 6 to move upward and pulls the drive rod 6 to move downward. At this time, by allowing the connecting piece 7 to slide in the strip-shaped hollow groove, it can make way and avoid interference.

[0060] Please see Figure 2 , Figure 6 The washing tank 1 is provided with an insertion tube 9, and multiple water inlets are provided on both sides of the insertion tube 9. The insertion tube 9 is connected to a liquid pump 10 located outside the washing tank 1, and the liquid outlet of the liquid pump 10 is connected to a spray pipe 11 located in the washing tank 1.

[0061] When the gas containing electronic grade isopropanol VOC is pumped into the washing tank 1, the liquid pump 10 will also start working simultaneously. At this time, the liquid pump 10 can extract the alkaline solution in the washing tank 1 through the insertion pipe 9 and pump it into the spray pipe 11. The alkaline solution can generate atomized gas through the spray pipe 11. This atomized gas can collide with the gas escaping from the alkaline solution and mix. At this time, the atomized gas and the gas escaping from the alkaline solution are in full contact, which can further treat the electronic grade isopropanol VOC that may remain in the gas, and further reduce the electronic grade isopropanol VOC content in the emission gas.

[0062] It should also be noted that, since the water inlet holes are located on both sides of the insertion pipe 9, when the liquid pump 10 draws alkaline solution through the insertion pipe 9, the alkaline solution tends to move towards the center in the washing tank 1. Under this tendency, the alkaline solution moves from the gas delivery end 12 towards the insertion pipe 9. This movement of the alkaline solution can actively drive the movement of the gas entering the washing tank 1 from the gas delivery end 12, thereby making the gas move a longer distance laterally in the washing tank 1, further increasing the residence time of the gas in the washing tank 1 and improving the treatment effect.

[0063] Furthermore, by placing the insertion tube 9 in the middle of the washing tank 1, the insertion tube 9 has a suction force on both sides of the alkaline solution, which can ensure the movement speed of the alkaline solution. Compared with the position placed on one side inside the washing tank 1, the movement speed of the alkaline solution can be guaranteed, thereby making the gas containing electronic grade isopropanol VOC move a longer distance laterally.

[0064] Please see Figure 1 , Figures 7-8 The pumping assembly is connected to the gas delivery end 12 and is used to pump electronic grade isopropanol VOC into the water washing tank 1. The pumping assembly is provided with a sealing element 18. The sealing element 18 can be switched in position to allow electronic grade isopropanol VOC to be pumped alternately toward the two sets of gas delivery ends 12.

[0065] The pump assembly includes a high-pressure air pump 24 installed on the side of the washing tank 1. The outlet of the high-pressure air pump 24 is connected to a switching pipe 17. Both sides of the switching pipe 17 are connected to two sets of air delivery ends 12, and the inner wall of the switching pipe 17 is slidably connected to the sealing member 18. When the sealing member 18 moves from one side of the inner wall of the switching pipe 17 to the other side, the pumping direction of electronic grade isopropanol VOC will change.

[0066] In this embodiment, by changing the position of the sealing member 18, the sealing member 18 can block one set of gas delivery ends 12. When the high-pressure gas pump 24 pumps the gas containing electronic grade isopropanol VOC into the switching tube 17, the gas can escape through the other set of gas delivery ends 12 and enter the washing tank 1. At this time, the gas containing electronic grade isopropanol VOC is absorbed by the alkaline solution on one side of the washing tank 1, and the alkaline solution on that side is slowly saturated. At this time, the alkaline solution on the other side of the washing tank 1 has a lower saturation than this side. By changing the position of the sealing member 18, the gas containing electronic grade isopropanol VOC can alternately enter the washing tank 1 through the two sets of gas delivery ends 12, thereby making the alkaline solutions on both sides of the washing tank 1 relatively uniformly saturated. On the one hand, it can ensure the absorption effect of electronic grade isopropanol VOC, and on the other hand, it can make full use of the alkaline solution.

[0067] When the liquid pump 10 is activated, it can draw alkaline solutions from both sides of the insertion pipe 9, so that the alkaline solutions on both sides of the washing tank 1 can move towards the center of the washing tank 1. When the pumping direction of the gas changes, the movement of the alkaline solution tends to drive the movement of the gas, thus ensuring that the gas can have a longer residence time in the alkaline solution under different pumping conditions.

[0068] Please see Figures 7-9 The triggering component is connected to the driving component and the blocking component 18. The triggering component can switch the position of the blocking component 18 when the tilting plate group has completed the deflection action. It includes: follower frame 13, transverse frame 16 and triggering structure.

[0069] The follower frame 13 is connected to the actuating end of the electric telescopic rod 8, and a horizontal groove 1301 is provided on the follower frame 13;

[0070] The transverse frame 16 is slidably disposed through the switching tube 17, the transverse frame 16 is connected to the sealing member 18, and the transverse frame 16 is provided with a connecting groove 1601 along its length direction;

[0071] In the initial state, the triggering structure acts on the side wall of the connecting groove 1601, causing the sealing member 18 to be in contact with the inner wall of one side of the switching pipe 17. At this time, one side of the switching pipe 17 is in a conductive state, and the other side is in a blocked state, allowing the gas pumped into the switching pipe 17 to enter the washing tank 1 through one of the air supply ends 12. When the electric telescopic rod 8 is activated to drive the tilting plate assembly to switch the deflection state, the follower frame 13 will follow suit and move when the horizontal groove 1301 abuts against the triggering structure. When connected, the trigger structure can passively store elastic potential energy. When the tilting plate group completes the deflection action, the trigger structure actively releases the elastic potential energy, which quickly switches the position of the sealing component 18 to change the gas pumping direction. That is, the gas pumping direction only changes when the tilting plate group completes the deflection action, so that when the gas pumping direction changes, the tilting plate group has already deflected to the predetermined position and can guide the gas entering the washing tank 1 in the opposite direction to ensure the residence time of the gas in the washing tank 1 when it moves in the opposite direction.

[0072] Specifically, during the process of the horizontal groove 1301 abutting against the trigger structure and the trigger structure being able to passively store elastic potential energy, the trigger structure is in a state of sliding in the connecting groove 1601. At this time, the switching tube 17 is under pressure, which causes the sealing member 18 to be in a state of contact with the inner wall of the switching tube 17, so that the sealing member 18 and the horizontal moving frame 16 can remain stationary in this state.

[0073] Please see Figure 7 , Figure 9The triggering structure connects the washing tank 1 and the connecting groove 1601. The triggering structure is provided with a second convex shaft 1401 that can slide in the horizontal groove 1301. When the follower frame 13 moves to the end of its stroke, the triggering structure can actively drive the sealing member 18 to perform a position switching action. The triggering structure includes a vertical plate 14 connected to the second convex shaft 1401. The vertical plate 14 is slidably connected to the guide member 23 provided on the washing tank 1, and a sliding connecting part 15 is installed on the vertical plate 14. The sliding connecting part 15 is slidably connected to the connecting groove 1601.

[0074] The upright plate 14 is also provided with a sliding groove 1402 along its length direction. A slider 19 is slidably installed in the sliding groove 1402. The slider 19 is connected to the side wall of the sliding groove 1402 by a column spring 21, and the slider 19 is rotatably installed with an abutment shaft 20 on the side facing the washing tank 1.

[0075] The triggering structure also includes an abutment 22 connected to the washing tank 1. The abutment 22 is adapted to the abutment shaft 20. The abutment 22 has two sets of inclined surfaces 2201 on one side facing the abutment shaft 20. The connection between the two sets of inclined surfaces 2201 forms an upwardly protruding part 2202. When the abutment shaft 20 moves along one set of inclined surfaces 2201 toward the protruding part 2202, the cylindrical spring 21 can be stretched.

[0076] In the initial state, the cylindrical spring 21 is stretched, which causes the slider 19 to have a downward pulling force. Under the action of this force, the abutment shaft 20 is in contact with one of the inclined surfaces 2201, so that the sliding connection part 15 can apply pressure to the side wall of the connecting groove 1601. At the same time, the sealing member 18 abuts against the inner wall of the switching tube 17, so that the sealing member 18 has high stability in this state, improving the sealing and fitting effect between it and the switching tube 17.

[0077] During the switching process, the electric telescopic rod 8 actuates, driving the follower frame 13 and drive rod 6 to move, allowing the inclined plate assembly to deflect in the opposite direction. Simultaneously, when the second convex shaft 1401 abuts against the end of the transverse groove 1301, the follower frame 13 drives the vertical plate 14 to move, causing the sliding connection 15 to move along the length of the connecting groove 1601. At this time, the abutment shaft 20 moves along the inclined surface 2201 towards the protrusion 2202, further stretching the cylindrical spring 21. When the drive rod 6 moves to the end of its stroke... When the abutment shaft 20 just moves past the protrusion 2202, the cylindrical spring 21 will release its elastic potential energy, driving the upright plate 14 to move actively. At the same time, the sliding connection part 15 moves to abut against the other side wall of the connecting groove 1601, so that the upright plate 14 can quickly drive the sealing part 18 to switch positions through the transverse frame 16, thereby changing the direction of gas pumping. This ensures that the gas can remain in a high compression state during the switching process, so that the gas enters the washing tank 1 with a faster transverse speed.

[0078] Specifically, the switching tube 17 has a T-shaped structure, with its inlet end perpendicular to the two sets of outlet ends. By quickly switching the position of the sealing element 18, the overlap time between the sealing element 18 and the inlet end can be shortened, effectively preventing the compressed gas from entering the water washing tank 1 from the two sets of air supply ends 12 when the sealing element 18 overlaps with the inlet end, causing a drop in injection pressure and resulting in the gas having too short a lateral movement distance in the water washing tank 1, which would prevent the electronic grade isopropanol VOC from being completely absorbed.

[0079] As an embodiment of the present invention, a method for using the electronic-grade isopropanol VOC-environmentally friendly circulating washing system as described above is also proposed, comprising the following steps:

[0080] Step 1: Connect the sealing cover on the electronic grade isopropanol VOC wastewater tank to the pump assembly via pipeline;
