Description

Technical Field

[0001] The invention relates to the technical field of isopropyl alcohol (VOC) treatment, and in particular to an electronic-grade isopropyl alcohol (VOC) environment-friendly circulating washing system and method. Background Art

[0002] In the electronics field, electronic-grade isopropyl alcohol is widely used due to its high purity, low impurity content and high solvency. However, its large-scale use will inevitably produce a large amount of electronic-grade isopropyl alcohol waste liquid, which contains a high level of electronic-grade isopropyl alcohol. Isopropyl alcohol is volatile and will cause environmental pollution if it is not treated and directly discharged into the atmosphere.

[0003] Most of the existing electronic grade isopropyl alcohol waste liquid treatment methods are to store the electronic grade isopropyl alcohol waste liquid in a wastewater pool and cover it with a sealing cover, and at the same time, regularly treat the isopropyl alcohol vapor generated inside the sealing cover.

[0004] In the process of treatment, a washing tower is mostly used to wash the isopropyl alcohol. Specifically, an alkaline solution is used to absorb the isopropyl alcohol to achieve the purpose of green emission. In the washing process, the isopropyl alcohol is mainly absorbed by spraying. However, the absorption of isopropyl alcohol by the alkaline solution is not completed instantly, and a certain amount of time is required. However, when the isopropyl alcohol vapor enters the washing tower, it will maintain a constant circulation state, resulting in a too short reaction time with the alkaline solution. Although the isopropyl alcohol content in the vapor can be reduced during washing, it cannot be completely eliminated. Summary of the invention

[0005] The object of the present invention is to provide an environmentally friendly circulating washing system and method for electronic grade isopropyl alcohol VOC to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: An electronic grade isopropyl alcohol VOC environmentally friendly circulating washing system, comprising: A water washing box, wherein two sets of air supply ends are symmetrically arranged on the side of the water washing box; A plurality of inclined plate groups are rotatably installed in the washing box, and the plurality of inclined plate groups are staggered along the horizontal direction of the space; A driving assembly connected to the inclined plate assembly, wherein the driving assembly can drive the inclined plate assembly to move so that the inclined plate assembly has two symmetrical deflection states; A pump air assembly is connected to the air supply end and is used to pump the electronic grade isopropyl alcohol VOC into the water washing box. A plugging member is provided in the pump air assembly. The plugging member can enable the electronic grade isopropyl alcohol VOC to be pumped alternately toward the two groups of the air supply ends by switching the position; A trigger assembly is connected to the driving assembly and the blocking member, and the trigger assembly can switch the position of the blocking member when the inclined plate group completes the deflection action.

When the deflection plate performs a deflection action, the telescopic plate can perform a telescopic action relative to the deflection plate.

[0008] As a further solution of the present invention: the guide structure includes a first convex shaft connected to the side of the telescopic plate, the first convex shaft passes through a through slot provided on the side of the deflection plate and extends to the outside of the deflection plate; The guide structure also includes a guide plate connected to the inner wall of the water washing box, and the guide plate is provided with a V-shaped groove slidably connected to the first convex shaft.

[0009] As a further solution of the present invention: the driving assembly includes a connecting rod connected to the rotating shaft of the deflection plate, and the end of the connecting rod away from the rotating shaft of the deflection plate is rotatably connected to a driving rod, and a connecting piece is slidably installed on the driving rod, and the connecting piece is connected to an electric telescopic rod fixedly installed on the side wall of the washing box.

[0010] As a further solution of the present invention: an insertion pipe is arranged in the water washing box, a plurality of water inlet holes are arranged on both sides of the insertion pipe, and the insertion pipe is connected to a liquid pump arranged outside the water washing box, and the liquid outlet of the liquid pump is connected to a spray pipe arranged in the water washing box.

[0011] As a further solution of the present invention: the pump air assembly includes a high-pressure air pump installed on the side of the water washing box, the air outlet of the high-pressure air pump is connected to a switching tube body, both sides of the switching tube body are connected to the two groups of air delivery ends, and the inner wall of the switching tube body is sealed and slidably connected to the sealing piece, when the sealing piece moves from one side of the inner wall of the switching tube body to the other side, the pumping direction of the electronic-grade isopropyl alcohol VOC will change.

[0012] As a further solution of the present invention: the trigger component includes: A follower frame connected to the action end of the electric telescopic rod, and the follower frame is provided with a transverse groove; A transverse frame is slidably arranged through the switching tube body, the transverse frame is connected to the blocking member, and the transverse frame is provided with a connecting groove along its length direction; A trigger structure is connected to the washing box and the connecting groove. The trigger structure is provided with a second convex shaft that can slide in the transverse groove. When the follower frame moves to the end of the stroke, the trigger structure can actively drive the blocking member to perform a position switching action.

[0013] As a further solution of the present invention: the trigger structure includes a vertical plate connected to the second convex shaft, a sliding connection portion is installed on the vertical plate, and the sliding connection portion is slidably connected to the connection groove; The vertical plate is also provided with a slide groove along its length direction, a slider is slidably installed in the slide groove, the slider is connected to the side wall of the slide groove through a columnar spring, and an abutment shaft is rotatably installed on one side of the slider toward the washing box; The trigger structure further includes an abutment member connected to the water washing box, wherein the abutment member is adapted to the abutment shaft.

[0014] As a further solution of the present invention: two groups of inclined surfaces are provided on the side of the abutment member facing the abutment shaft, and an upwardly protruding protrusion is formed at the connection between the two groups of inclined surfaces. When the abutment shaft moves along one group of the inclined surfaces toward the protrusion, the cylindrical spring can be stretched.

[0015] A method for using the electronic grade isopropyl alcohol VOC environmentally friendly circulating washing system as described above comprises the following steps: Step 1: Connect the sealing cover on the electronic grade isopropyl alcohol VOC wastewater pool to the pump gas assembly through pipelines; Step 2: Start the pump gas component, which can pump the gas generated in the electronic grade isopropyl alcohol VOC wastewater pool into the water washing box; Step 3: The gas entering the water washing box has a high speed and can move along multiple groups of inclined plates and be absorbed by the alkaline solution in the water washing box; Step 4: The gas is decelerated until, under the action of buoyancy, it moves above the surface of the alkaline solution, completing the water washing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By setting the inclined plate group, when the gas acts on the inclined plate group, it can move downwardly under the guidance of the inclined plate group, thereby suppressing the tendency of the gas to move upward due to the buoyancy, thereby increasing the retention time of the gas in the alkaline solution, and when the horizontal speed of the gas drops to zero, the gas can also move in the opposite direction along the inclined plate group, so that the gas can have a horizontal reverse movement process, during which the retention time of the gas in the alkaline solution is further increased, so that the alkaline solution has a longer time to absorb the electronic-grade isopropyl alcohol VOC, thereby ensuring the absorption effect of the electronic-grade isopropyl alcohol VOC, reducing the content of the electronic-grade isopropyl alcohol VOC escaping from the gas in the alkaline solution, and achieving the effect of green emission; By setting the insertion pipe, liquid pump and spray pipe, not only can the atomized alkaline solution be fully contacted with the gas of the alkaline solution, but also the electronic grade isopropyl alcohol VOC that may remain in the gas can be treated again, further reducing the electronic grade isopropyl alcohol VOC content in the exhaust gas, and the alkaline solution can have a tendency to move toward the middle in the water washing box. Under this tendency, the alkaline solution has a process of moving from the air supply end toward the insertion pipe, and the movement of the alkaline solution can actively drive the movement of the gas entering the water washing box from the air supply end, so that the gas can make a longer lateral displacement distance in the water washing box, further increasing the retention time of the gas in the water washing box and improving the treatment effect; By setting up the trigger component and the pump air component, by changing the position of the blocking piece, the gas containing electronic-grade isopropyl alcohol VOC can be alternately fed into the water washing box from the two groups of air supply ends, so that the alkaline solutions on both sides of the water washing box can be relatively evenly saturated. On the one hand, the absorption effect of the electronic-grade isopropyl alcohol VOC can be ensured, and on the other hand, the alkaline solution can be fully utilized. At the same time, by quickly switching the position of the blocking piece, the overlap time of the blocking piece and the air inlet end can be shortened, which effectively prevents the compressed gas from entering the water washing box from the two groups of air supply ends when the blocking piece overlaps with the air inlet end, causing a drop in the injection pressure, and causing the lateral movement distance of the gas in the water washing box to be too short, so that the electronic-grade isopropyl alcohol VOC cannot be completely absorbed.

DETAILED DESCRIPTION

[0027] 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.

[0028] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0029] See also Figure 1 to Figure 9 In an embodiment of the present invention, an electronic grade isopropyl alcohol VOC environmentally friendly circulating washing system includes: a water washing box 1, a plurality of inclined plate groups, a driving component, a pump air component and a trigger component.

[0030] Two groups of air supply ends 12 are symmetrically arranged on the side of the water washing box 1. The water washing box 1 contains an alkaline solution, which can absorb the isopropyl alcohol VOC in the gas generated in the electronic grade isopropyl alcohol VOC wastewater pool to ensure that the discharged gas does not contain isopropyl alcohol VOC during discharge, thereby achieving the purpose of green discharge; A plurality of inclined plate groups are rotatably installed in the water washing box 1, wherein the alkaline solution in the water washing box 1 should completely immerse the inclined plate groups, the plurality of inclined plate groups are staggered in the horizontal direction of space, and the rotating axes of the plurality of inclined plate groups are in the same horizontal plane.

[0031] In the initial state, the multiple sets of inclined plates are parallel and inclined (see Figure 5 ), at this time, the gas containing electronic grade isopropyl alcohol VOC pressurized by the pump gas assembly enters the water washing box 1 and moves rapidly in the horizontal direction. Specifically, we take the upper end of the inclined plate group as end a and the lower end as end b, then the gas moves from end a to end b. At the same time, when the gas moves horizontally, the gas is also affected by buoyancy and moves upward, so that when the gas acts on the inclined plate group, it can move downward obliquely under the guidance of the inclined plate group, thereby suppressing the upward movement of the gas due to buoyancy, thereby increasing the retention time of the gas in the alkaline solution, and under the action of the alkaline solution Under this condition, the horizontal movement speed of the gas will decrease, and when the horizontal speed of the gas drops to zero, the gas can also 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 retention time of the gas in the alkaline solution is further increased, so that the alkaline solution has a longer time to absorb the electronic-grade isopropyl alcohol VOC, thereby ensuring the absorption effect of the electronic-grade isopropyl alcohol VOC, reducing the content of electronic-grade isopropyl alcohol VOC in the gas escaping from the alkaline solution, and achieving the effect of green emission.

[0032] See also Figure 3~Figure 5The inclined plate group includes a deflection plate 2 rotatably mounted in the washing box 1, the interior of the deflection plate 2 is a hollow structure, and telescopic plates 3 are sealed and slidably mounted at both ends of the deflection plate 2; The inclined plate group further includes a guide structure connecting the telescopic plate 3 and the washing box 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 penetrates the through slot 201 provided on the side of the deflection plate 2 and extends to the outside of the deflection plate 2. The guide structure also includes a guide plate 4 connected to the inner wall of the washing box 1, and a V-shaped groove 401 is provided on the guide plate 4 for sliding connection with 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.

[0033] In the initial state, the deflection plate 2 is in an inclined state. At this time, the first protruding shaft 301 on the telescopic plate 3 at one end of the deflection plate 2 is at the end of one end of the V-shaped groove 401 matched therewith, and the first protruding shaft 301 on the other set of telescopic plates 3 is at the end of the other end of the V-shaped groove 401 matched therewith. In this state, it can be ensured that the deflection plate 2 can form a maximum length with the two sets of telescopic plates 3, so that the two adjacent sets of inclined plate groups can have an overlapping area along the horizontal plane, so as to ensure that when the gas moves laterally, it can have the effect of suppressing the rise under the guidance of the inclined plate group. When the driving component is activated to switch the inclined plate group to the inclined state, the deflection plate 2 will actively deflect, and the two sets of telescopic plates 3 connected thereto will make a circular motion. The corresponding first convex shaft 301 will move along the V-shaped 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 groups of deflection plates 2 are deflected to a 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-shaped groove 401, so that the telescopic plate 3 can extend outward toward the deflection plate 2 to the maximum amount, thereby maintaining the state of the two adjacent groups of inclined plate groups having an overlapping area along the horizontal plane, so that when the gas containing electronic grade isopropyl alcohol VOC is ejected through the other group of gas delivery ends 12, the gas can also have a longer retention time in the alkaline solution.

[0034] See also Figure 1~Figure 4The driving assembly is connected to the deflection plate 2, and the driving assembly can drive the inclined plate group to move, so that the inclined plate group has two symmetrical deflection states. The driving assembly includes a connecting rod 5 connected to the rotating shaft of the deflection plate 2, and the end of the connecting rod 5 away from the rotating shaft of the deflection plate 2 is rotatably connected to a driving rod 6, and a connecting piece 7 is slidably installed on the driving rod 6, and the connecting piece 7 is connected to an electric telescopic rod 8 fixedly installed on the side wall of the washing box 1.

[0035] Among them, for two adjacent groups of deflection plates 2, the distance between the corresponding connecting rods 5 on the driving rod 6 is equal to the distance between the rotation axes of the two groups of deflection plates 2, so that the connecting line of the two groups of connecting rods 5, the driving rod 6 and the rotation axes of the two groups of deflection plates 2 forms a parallelogram, so that when the driving rod 6 moves, multiple groups of deflection plates 2 can be driven to deflect synchronously, so that multiple groups of inclined plate groups can maintain a parallel state during the static and deflection processes, thereby improving the guiding effect on the gas and avoiding excessive resistance to the gas movement due to the excessive inclination angle of a certain group of inclined plate groups, causing the gas to be forced to stop moving and rise under the action of buoyancy.

[0036] It should be noted that a strip-shaped hollow groove is formed at the end of the driving rod 6, and the connecting member 7 passes through the strip-shaped hollow groove, and multiple sets of rollers are rotatably installed on both sides of the connecting member 7, and the rollers are in a rolling fit with both sides of the driving rod 6. The significance of such a setting is that when the electric telescopic rod 8 drives the driving rod 6 to move, the connecting rod 5 makes a circular motion, which has the process of supporting the driving rod 6 to move upward and pulling the driving rod 6 to move downward. At this time, the connecting member 7 can make way by sliding in the strip-shaped hollow groove to avoid interference.

[0037] See also Figure 2 , Figure 6 An insertion pipe 9 is provided in the water washing box 1, and a plurality of water inlet holes are provided on both sides of the insertion pipe 9. The insertion pipe 9 is connected to a liquid pump 10 provided outside the water washing box 1, and the liquid outlet of the liquid pump 10 is connected to a spray pipe 11 provided in the water washing box 1.

[0038] When the gas containing electronic-grade isopropyl alcohol VOC is pumped into the water washing tank 1, the liquid pump 10 will also start working synchronously. At this time, the liquid pump 10 can extract the alkaline solution in the water washing tank 1 through the insertion tube 9 and pump it into the spray pipe 11. The alkaline solution can produce atomized gas through the spray pipe 11. The part of the atomized gas can collide with the gas escaping from the alkaline solution and mix. At this time, the atomized gas is in full contact with the gas escaping from the alkaline solution, and the electronic-grade isopropyl alcohol VOC that may remain in the gas can be processed again, thereby further reducing the electronic-grade isopropyl alcohol VOC content in the exhaust gas.

[0039] It should also be noted that since the water inlet holes are arranged on both sides of the insertion tube 9, when the liquid pump 10 extracts the alkaline solution through the insertion tube 9, the alkaline solution has a tendency to move toward the middle of the water washing box 1. Under this tendency, the alkaline solution has a process of moving from the air supply end 12 toward the insertion tube 9, and the movement of the alkaline solution can actively drive the movement of the gas entering the water washing box 1 from the air supply end 12, so that the gas can make a longer lateral displacement distance in the water washing box 1, further increasing the retention time of the gas in the water washing box 1 and improving the treatment effect.

[0040] Furthermore, by arranging the insertion tube 9 in the middle of the water washing box 1, the insertion tube 9 has a suction force on the alkaline solution on both sides thereof, thereby being able to ensure the movement speed of the alkaline solution. Compared with the position arranged on one side inside the water washing box 1, the movement speed of the alkaline solution can be ensured, thereby making the lateral movement distance of the gas containing electronic grade isopropyl alcohol VOC longer.

[0041] See also Figure 1 , Figure 7~Figure 8 The pump air assembly is connected to the air supply end 12 and is used to pump the electronic grade isopropyl alcohol VOC into the water washing box 1. A plugging member 18 is provided in the pump air assembly. The plugging member 18 can enable the electronic grade isopropyl alcohol VOC to be pumped alternately toward the two groups of the air supply ends 12 by switching the position; The pump air assembly includes a high-pressure air pump 24 installed on the side of the washing box 1, and the air outlet of the high-pressure air pump 24 is connected to the switching tube body 17. The two sides of the switching tube body 17 are connected to the two groups of the air delivery ends 12, and the inner wall of the switching tube body 17 is sealed and slidably connected to the blocking member 18. When the blocking member 18 moves from one side of the inner wall of the switching tube body 17 to the other side, the pumping direction of the electronic-grade isopropyl alcohol VOC will change.

[0042] In this embodiment, by changing the position of the blocking member 18, the blocking member 18 can block one of the groups of air supply ends 12, so that when the high-pressure air pump 24 pumps the gas containing electronic-grade isopropyl alcohol VOC into the switching tube body 17, the gas can escape through the other group of air supply ends 12 and enter the water washing box 1. At this time, the gas containing electronic-grade isopropyl alcohol VOC is absorbed by the alkaline solution on one side of the water washing box 1, and the alkaline solution on this side is slowly saturated. At this time, the alkaline solution on the other side of the water washing box 1 has a lower saturation than this side. By changing the position of the blocking member 18, the gas containing electronic-grade isopropyl alcohol VOC can be alternately entered into the water washing box 1 from the two groups of air supply ends 12, so that the alkaline solutions on both sides of the water washing box 1 can be relatively evenly saturated. On the one hand, it can ensure the absorption effect of electronic-grade isopropyl alcohol VOC, and on the other hand, it can make full use of the alkaline solution.

[0043] Among them, when the liquid pump 10 is in operation, the alkaline solution on both sides of the injection tube 9 can be extracted, and the alkaline solution on both sides of the water washing tank 1 can move relatively toward the middle of the water washing tank 1. When the pumping direction of the gas changes, the movement of the alkaline solution has a tendency to drive the movement of the gas, thereby ensuring that the gas can have a longer retention time in the alkaline solution in different pumping states.

[0044] See also Figure 7~Figure 9 The trigger assembly is connected to the driving assembly and the blocking member 18. The trigger assembly can switch the position of the blocking member 18 when the tilting plate group completes the deflection action, and includes: a follower frame 13, a transverse frame 16 and a trigger structure.

[0045] The follower frame 13 is connected to the action end of the electric telescopic rod 8, and a transverse groove 1301 is provided on the follower frame 13; The transverse frame 16 is slidably arranged to penetrate the switching tube body 17, the transverse frame 16 is connected to the blocking member 18, and the transverse frame 16 is provided with a connecting groove 1601 along its length direction; In the initial state, the trigger structure acts on the side wall of the connecting groove 1601, so that the blocking member 18 is in a state of being in contact with the inner wall of one side of the switching tube body 17. At this time, one side of the switching tube body 17 is in a conducting state, and the other side is in a blocking state, so that the gas pumped into the switching tube body 17 can enter the washing box 1 through one of the gas supply ends 12. When the electric telescopic rod 8 moves to drive the tilting plate group to switch the deflection state, the follower frame 13 will follow the action, and when the transverse groove 1301 contacts the trigger structure, the follower frame 13 will follow the action. When connected, the trigger structure can passively store elastic potential energy. When the inclined plate group completes the deflection action, the trigger structure actively releases the elastic potential energy, and quickly switches the position of the blocking member 18 to change the pumping direction of the gas, that is, the pumping direction of the gas is changed when the inclined plate group completes the deflection action, so that when the gas pumping direction changes, the inclined plate group has deflected to a predetermined position and can guide the gas entering the water washing box 1 in the opposite direction to ensure the retention time of the gas in the water washing box 1 when it moves in the opposite direction.

[0046] Specifically, when the transverse groove 1301 abuts against the trigger structure and the trigger structure is 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 body 17 is in a pressurized state, so that the blocking member 18 is in a state of being in contact with the inner wall of the switching tube body 17. In this state, the blocking member 18 and the transverse frame 16 can remain stationary.

[0047] See also Figure 7 , Fig. 9, the trigger structure connects the washing box 1 and the connecting groove 1601, and is provided with a second convex shaft 1401 that can slide in the transverse groove 1301. When the follower frame 13 moves to the end of the stroke, the trigger structure can actively drive the blocking member 18 to perform a position switching action. The trigger structure includes a vertical plate 14 connected to the second convex shaft 1401, and the vertical plate 14 is slidably connected to the guide member 23 provided on the washing box 1, and a sliding connection part 15 is installed on the vertical plate 14, and the sliding connection part 15 is slidably connected to the connecting groove 1601; The vertical plate 14 is also provided with a slide groove 1402 along its length direction, and a slider 19 is slidably installed in the slide groove 1402. The slider 19 is connected to the side wall of the slide groove 1402 through a columnar spring 21, and the slider 19 is rotatably installed with an abutment shaft 20 toward one side of the washing box 1; The trigger structure also includes an abutment member 22 connected to the washing box 1, and the abutment member 22 is adapted to the abutment shaft 20. Two groups of inclined surfaces 2201 are provided on the side of the abutment member 22 facing the abutment shaft 20, and an upwardly protruding protrusion 2202 is formed at the connection between the two groups of inclined surfaces 2201. When the abutment shaft 20 moves along one group of the inclined surfaces 2201 toward the protrusion 2202, the cylindrical spring 21 can be stretched.

[0048] In the initial state, the cylindrical spring 21 is in a stretched state, so that in this state, the slider 19 has a force pulling it downward. Under the action of this force, the abutment shaft 20 is in an abutment state 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 body 17, so that in this state, the sealing member 18 has higher stability, thereby improving the sealing and fitting effect between it and the switching tube body 17.

[0049] During the switching process, the electric telescopic rod 8 moves, and drives the follower frame 13 and the driving rod 6 to move, so that the inclined plate group can deflect in the opposite direction. At the same time, when the second convex shaft 1401 abuts against the end of the transverse groove 1301, the follower frame 13 can drive the vertical plate 14 to move, and make the sliding connection part 15 move along the length direction of the connecting groove 1601. At this time, the abutting shaft 20 moves along the inclined surface 2201 toward the protruding part 2202, so that the cylindrical spring 21 is further stretched, and when the driving rod 6 moves to the end of the stroke, the cylindrical spring 21 is further stretched. At this time, the abutment shaft 20 just moves over the protrusion 2202. At this time, the columnar spring 21 will release its elastic potential energy and drive the vertical plate 14 to actively move. 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 vertical plate 14 can quickly drive the sealing member 18 to switch position through the transverse frame 16, thereby changing the direction in which the gas is pumped, ensuring that during the switching process, the gas can remain in a high compression state, and the gas has a faster transverse speed when it enters the washing box 1.

[0050] Specifically, the switching tube body 17 is a T-shaped structure, and its air inlet end is in a vertical state with the two sets of air outlet ends. By quickly switching the position of the blocking member 18, the overlap time of the blocking member 18 and the air inlet end can be shortened, thereby effectively preventing the compressed gas from entering the water washing box 1 from the two sets of air supply ends 12 when the blocking member 18 overlaps with the air inlet end, causing the injection pressure to drop, and causing the lateral movement distance of the gas in the water washing box 1 to be too short, so that the electronic-grade isopropyl alcohol VOC cannot be completely absorbed.

[0051] As an embodiment of the present invention, a method for using the electronic grade isopropyl alcohol VOC environmentally friendly circulating washing system as described above is also proposed, comprising the following steps: Step 1: Connect the sealing cover on the electronic grade isopropyl alcohol VOC wastewater pool to the pump gas assembly through pipelines; Step 2: Start the pump gas component, which can pump the gas generated in the electronic grade isopropyl alcohol VOC wastewater pool into the water washing box 1; Step 3: The gas entering the water washing box 1 has a relatively high velocity and can move along the multiple groups of inclined plates and be absorbed by the alkaline solution in the water washing box 1; Step 4: The gas is decelerated until, under the action of buoyancy, it moves above the surface of the alkaline solution, completing the water washing.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0053] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
