[0003] Industrial waste gas contains a large amount of impurity particles and other substances, which need to be subjected to a series of purification treatments to meet the emission standards.

[0030] A purification method for a penetrating filter type gas purification system comprises the following steps:

[0031] S1. Connect the air intake pipe to the exhaust outlet, start the drive motor and the one-way valve through the PLC controller, and start to let the exhaust gas in. The drive motor controls the rotation of the rotating ring, thereby indirectly controlling the output of the gear, and the gear drives the circular motion of the rotating core in the compression mechanism;

[0032] S2, the exhaust gas enters the compression mechanism, and the exhaust gas is compressed in the compression mechanism through the action of the guide component, and then discharged from the exhaust pipe;

[0033] S3. During the compression process, the position of the filter element in the purification component is changed in real time according to the rotation speed of the gear, that is, the compression speed, to match the exhaust gas purification process under different conditions. The exhaust gas is discharged from the external pipe after being purified by the filter element. When the filter element is saturated, it can be replaced by replacing it from the cover plate.

[0034] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0035] 1. By sequentially arranging an air inlet pipe, a compression mechanism, an air outlet pipe, a purification component and an external pipe, the exhaust gas is allowed to enter the purification system in a unidirectional manner. After passing through the compression mechanism, the exhaust gas is compressed in volume, so that the average distance between the impurity particles contained in the exhaust gas is reduced, so that these impurity particles can be distributed more concentratedly, and then when the exhaust gas passes through the filter element, the impurity particles therein can be filtered and purified more quickly to improve the purification effect.

[0036] 2. By additionally arranging a purification adjustment component below and on one side of the purification component, the purification adjustment component is synchronously adjusted according to the speed of the exhaust gas entering the exhaust pipe, and at the same time drives the filter element to move and adjust in the connecting pipe, so that the position of the filter element can purify the exhaust gas in time.

[0037] In summary, the present invention effectively improves the self-adjustment adaptability of the purification system and ensures the purification effect of the exhaust gas. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0050] like Figure 1-2 As shown, the present invention provides a technical solution: a penetration filtering gas purification system, including a support component, a compression mechanism, a purification component 5, a purification adjustment component 7 and a driving mechanism 8;

[0051] The support assembly includes a base plate and two support frames 1 vertically installed on the base plate. The support frames 1 are connected to the base plate by welding or bolting. A PLC controller 11 is installed on the side wall of one of the support frames 1 by screws, and a horizontally arranged guide member 12 and a fixed shaft 13 are installed on the side wall of the other support frame 1. The guide member 12 is a rectangular structure, and a vertically penetrating fixing hole is opened on the guide member 12. The fixing hole is arranged along the length direction of the guide member 12. The guide member 12 is located above the fixed shaft 13. The fixed shaft 13 and the side wall of the support frame 1 are fixed by a threaded connection, and the guide member 12 and the side wall of the support frame 1 are fixed by screws.

[0052] The compression mechanism is horizontally arranged between the support frames 1 on both sides, and is externally connected with an air inlet pipe 3 and an air outlet pipe 4 which are arranged relatively oppositely. The exhaust gas enters the compression mechanism through the air inlet pipe 3. After compression, the distance between gas molecules decreases, but the size and properties of the impurity particles contained in the gas do not change due to the compression of the gas. However, due to the reduction in gas volume, the relative position of the impurity particles in the gas will become closer, that is, the average distance between them will decrease, so that the impurity particles in the exhaust gas discharged from the air outlet pipe 4 can be more concentratedly adsorbed and purified.

[0053] like Figure 3-4 As shown, the compression mechanism includes a fixed box 2, a connecting seat 21, an adjustment plate 23, a rotating core 24 and a flow guide assembly;

[0054] The fixed box 2 is a circular structure with a hollow structure inside. Guide grooves 22 are provided on the inner top surface and the inner bottom surface of the fixed box 2. The guide grooves 22 are annular.

[0055] An inlet and an outlet that are relatively arranged are provided in the fixed box 2. Connecting seats 21 are installed on the outer wall of the fixed box 2 corresponding to the positions of the inlet and the outlet by bolts. The air inlet pipe 3 and the air outlet pipe 4 are respectively installed between the inner walls of the two connecting seats 21. A one-way valve (not shown in the figure) is installed between the inner walls of the inlet and the outlet to control the flow direction of the exhaust gas and prevent backflow.

[0056] The adjustment plate 23 is arranged in an "L"-shaped structure. The adjustment plate 23 is arranged between the inner walls of the fixed box 2 near the side of the air outlet pipe 4. An inner groove along the arc structure is also opened between the inner walls of the fixed box 2 (near the position of the air outlet pipe 4). An arc-shaped guide rod 27 is welded between the inner walls of the inner groove. An adjustment spring 1 is arranged on the guide rod 27. One end of the adjustment spring 1 is fixed to the inner wall of one end of the inner groove. One end of the adjustment plate 23 slides on the outer wall of the guide rod 27, and the other end of the adjustment spring 1 is connected to the side wall of the adjustment handle. The other end of the adjustment plate 23 elastically slides along the arc trajectory, and a magnetic attraction sheet 231 is installed on the surface of the side of the adjustment plate 23 facing the center of the fixed box 2.

[0057] When the force applied to the adjusting spring by the adjusting plate 23 is the smallest, one end of the adjusting plate 23 contacts the inner wall of the outlet in the fixed box 2, thereby blocking the outlet.

[0058] The cross section of the rotating core 24 is a regular hexagon, and it is arranged between the inner top wall and the inner bottom wall of the fixed box 2 in an eccentrically rotating manner. A mounting seat 241 is installed at three end corners of the rotating core 24 by screws, and a bayonet is opened on the mounting seat 241, which matches the movable range of the adjustment plate 23, and a flow guide component is arranged on one side of each mounting seat 241 by an axial connection, wherein the mounting seat 241 and the flow guide component are in seamless contact, and the flow guide component and the inner top wall (or inner bottom wall) of the fixed box 2 are also in seamless contact, thereby ensuring that there is no gas overflow problem between adjacent compression spaces.

[0059] The flow guide assembly includes a connecting plate 1 25 and a connecting plate 2 26, one end of the connecting plate 1 25 is rotatably connected to the mounting seat 241 through an axis, and an open fixing groove 1 is provided on the connecting plate 1 25, and at least two adjusting springs 2 are fixedly installed on the inner wall of one end of the fixing groove 1, and one end of the connecting plate 2 26 is a cylindrical structure and the end is always in sliding contact with the inner wall of the fixed box 2 (wherein, the outer surface of the cylindrical end of the connecting plate 2 26 can be connected and fixed to the magnetic suction sheet 231 through suction, and there is no connection between the outer surface of the cylindrical end and the inner wall of the fixed box 2 Suction exists), a guide shaft 261 is provided through the end of the connecting plate 26, and the guide shaft 261 and the connecting plate 26 are also in rotational contact, and the guide shaft 261 slides between the guide grooves 22 on the inner top surface and the inner bottom surface, and a convex plate 262 connected to the connecting plate 1 25 is provided on one end of the connecting plate 26 facing the connecting plate 1 25, and the convex plate 262 is in a "T"-shaped structure and one end of the convex plate 262 slides between the inner walls of the fixed groove 1, and the other end of the adjusting spring 2 is connected and fixed to the end face of the convex plate 262, and there is a seamless sliding contact between the convex plate 262 and the fixed groove 1.

[0060] It should be further explained that the rotating core 24 is pressed Figure 4As shown, it performs circular motion in the clockwise direction. As the rotating core 24 rotates, the guide component moves synchronously with the mounting seat 241 on the rotating core 24. Due to the eccentric setting structure of the rotating core 24, the guide component will produce elastic conditions when rotating due to the distance from the inner wall of the fixed box 2, wherein the interval formed between the adjacent guide components and the inner top wall and inner bottom wall of the fixed box 2, and the outer surface of the rotating core 24 is represented as a compression interval, and the volume of the corresponding compression interval at the inlet of the fixed box 2 is greater than the volume of the corresponding compression interval at the outlet of the fixed box 2, so that the exhaust gas entering the fixed box 2 from the intake pipe 3 can be compressed when it reaches the outlet pipe 4, thereby changing the average distance between the impurity particles in the exhaust gas, making it easier to be purified in a concentrated manner.

[0061] A driving mechanism 8 is installed at the bottom of the compression mechanism. The setting of the driving mechanism 8 can drive the operation of the compression mechanism and change the compression speed.

[0062] like Figure 5 As shown, the driving mechanism 8 includes a bottom cover 81, a rotating ring 82, a gear 83, a worm 84, a driving motor 85 and an external shaft 86;

[0063] An external shaft 86 of a "⊥"-shaped structure is fixed in the middle of the bottom wall of the fixed box 2 by screws, and two shaft seats are also installed on the bottom wall of the fixed box 2 by screws, and a driving motor 85 is installed on the side wall of one of the shaft seats by screws. The driving motor 85 is a rotating motor, and a worm 84 is installed on the output end of the driving motor 85, and the worm 84 is rotatably set between the two shaft seats.

[0064] A bottom cover 81 fixed to the bottom wall of the rotating ring 82 is installed by screws, and its top surface is in rotational contact with the bottom wall of the fixed box 2. The bottom cover 81 is a circular structure. A connecting sleeve is installed in the middle of the top surface of the bottom cover 81 by screws. The connecting sleeve is adapted to be connected to the circumscribed shaft 86 and is rotatably arranged therewith. Worm gear teeth connected to the rotating ring 82 are evenly distributed on the outer ring surface, and the worm gear teeth are meshed with the worm 84 for transmission, and tooth grooves are evenly opened on the inner ring surface of the rotating ring 82.

[0065] One side of the rotating core 24 is connected to a gear 83 on the bottom wall of the fixed box 2 through the same output shaft. The gear 83 is meshed between the tooth grooves. The output shaft, the rotating core 24 and the gear 83 are fixed together through a key connection. The output shaft is also rotatably set between the inner walls of the fixed box 2, and the bottom end of the output shaft is rotatably set between the inner walls of the bottom cover 81.

[0066] It should be further explained that the driving motor 85 is started by the PLC controller 11, so that it drives the worm 84 to rotate and output, so that the worm 84 controls the rotation of the rotating ring 82 through the meshing transmission. During the rotation of the rotating ring 82, the gear 83 is also driven to rotate and output through the meshing transmission, so that the rotating core 24 rotates synchronously with the gear 83 through the output shaft.

[0067] However, a purification component 5 is installed at the end of the outlet pipe 4, and an external pipe 6 is also installed at the tail of the purification component 5. The inner diameter and outer diameter of the outlet pipe 4 and the external pipe 6 are the same, and the inner diameter of the connecting pipe 51 is equal to the outer diameter of the outlet pipe 4. When the exhaust gas enters the purification component 5 through the outlet pipe 4, the impurity particles therein are adsorbed and purified, and finally the purified exhaust gas is discharged from the external pipe 6.

[0068] In addition, a purification adjustment component 7 is provided below and on one side of the purification component 5. The flow rate of the exhaust gas in the exhaust pipe 4 is used to control the purification adjustment component 7 to adjust the position of the filter element 53 of the purification component 5 in real time to match the purification position under different compression speeds.

[0069] like Figure 6-8 As shown, the purification assembly 5 includes a connecting pipe 51, a cover plate 52, a filter element 53 and an adjustment plate 23;

[0070] The connecting pipe 51 is installed between the air outlet pipe 4 and the external pipe 6 by means of a threaded connection. A limiting seat 41 is installed on the outer wall of the air outlet pipe 4 by means of screws, and a limiting seat 61 is installed on the outer wall of the external pipe 6 by means of screws. The limiting seat 41 and the limiting seat 61 are arranged opposite to each other and are both arranged in a "U"-shaped structure.

[0071] A through hole 1 is provided in the middle of the outer surface of the connecting tube 51, and the through hole 1 is arranged vertically upward. Fixing seats 511 are installed on the outer walls of the connecting tube 51 on both sides of the through hole 1 by screws. A cover plate 52 is installed between the inner walls of the through hole 1 and is sealed therewith. The curvature of the cover plate 52 is consistent with the curvature of the tube wall of the connecting tube 51, and ridges 521 are installed on the outer surfaces of the two ends of the cover plate 52 by screws. The ridge 521 is fixed between the two fixing seats 511 on the same side by fastening screws.

[0072] The filter element 53 is a cylindrical structure, and the filter element 53 can be disassembled and installed from one through hole, and a movable column 531 that moves and adjusts synchronously with the filter element 53 is connected to the middle of the bottom of the filter element 53 by plugging, and the other end of the movable column 531 slides between the inner walls of the fixed hole, and a limit plate 54 is slidably arranged between the limit seat 1 41 and the limit seat 2 61, and the curvature of the limit plate 54 is consistent with the curvature of the tube wall of the connecting tube 51, and the curvature of the limit plate 54 is consistent with the curvature of the air outlet pipe 4 and the external tube 6, and the limit plate 54 slides between the inner walls of the tube wall of the connecting tube 51 (that is, a through hole 2 that is compatible with the adjusting plate 23 is opened on the connecting tube 51 on the movement path of the adjusting plate 23, and the through hole 2 is vertically downwardly arranged, and the through hole 2 is not shown in the figure), and a sealing strip is embedded on the inner wall of the connecting tube 51 that contacts the adjusting plate 23, so as to ensure the sealing at the sliding contact position.

[0073] It should be further explained that by unscrewing the fastening screws on both sides, removing the cover plate 52 from the connecting pipe 51, and then moving the filter element 53 to a position of the through hole, it can be taken out vertically upward, and then the new filter element 53 can be installed on the movable column 531 by plugging, and then the cover plate 52 is covered and the fastening screws are tightened.

[0074] The purification adjustment component 7 includes an adjustment arm 71, an external seat 72, a movable seat 73, a fixed pulley 74 and a guide plate 75;

[0075] A movable seat 73 is slidably arranged between the opposite side walls of the guide member 12. A fixing groove 2 is opened on the side walls of the guide member 12 along its length direction. The side walls of the movable seat 73 are provided with integrated protrusions. The protrusions slide between the inner walls of the fixing groove 2. One end of the movable seat 73 also slides on the outer wall of the fixed shaft 13. A side shaft 731 is installed between the side walls of the movable seat 73 by threaded connection.

[0076] On one side of the fixed hole, two fixed pulleys 74 are rotatably connected by an axis between the inner walls of the guide member 12. The two fixed pulleys 74 are distributed up and down, and a pull rope is arranged between the two fixed pulleys 74. One end of the pull rope is fixed to the outer surface of the movable column 531, and the other end is fixed to the side wall of the movable seat 73. On the other side of the fixed hole, a "T"-shaped connecting bolt 121 is fixed by welding on the top surface of the guide member 12. A tension spring 9 is connected between the connecting bolt 121 and the connecting column. A cavity is opened on the connecting column and is arranged toward the connecting bolt 121. A connecting shaft (not shown in the figure) is welded in the cavity, and one end of the tension spring 9 is connected to the connecting shaft.

[0077] External seats 72 are installed at two opposite positions on the outer wall of the exhaust pipe 4 by screws, and a synchronous shaft 721 is rotatably arranged between the two external seats 72. The synchronous shaft 721 passes through the exhaust pipe 4 and a guide plate 75 that rotates synchronously therewith is connected in the middle of the synchronous shaft 721. When the pulling force of the tension spring 9 on the movable column 531 exceeds the sum of the pulling force of the pull rope on the movable column 531 and the thrust of the exhaust gas on the guide plate 75, the guide plate 75 is reset and adjusted under the action of the tension spring 9. When the movable column 531 is reset to contact the inner wall of one end of the fixing hole close to the connecting bolt 121, the guide plate 75 is set in a vertical downward state. Adjustment arms 71 that rotate and adjust synchronously therewith are connected at both ends of the synchronous shaft 721. A through hole three is opened on the adjusting arm 71 along its length direction, and the side shaft 731 slides between the inner walls of the through hole three.

[0078] It should be further explained that the compressed exhaust gas is discharged from the exhaust pipe 4, and when passing through the guide plate 75, the flow of the exhaust gas drives it to be deflected and adjusted. When the guide plate 75 rotates, the adjustment arms 71 on both sides are synchronously driven to swing, so that the adjustment arms 71 control the movement and adjustment of the moving seat 73 on the guide member 12, and then the position of the filter element 53 is synchronously adjusted by driving the horizontal movement of the moving column 531 to meet the purification needs under different conditions.

[0079] When the rotation speed of the rotating core 24 is accelerated, the speed at which the exhaust gas in the compression area enters the exhaust pipe 4 is also accelerated, so that the swing amplitude of the guide plate 75 becomes larger, and the adjusting arm 71 increases with the swing angle of the guide plate 75, and the movable seat 73 moves and adjusts along with the adjusting arm 71 to the side close to the position of the connecting bolt 121 (at this time, the sum of the thrust of the exhaust gas on the guide plate 75 and the pulling force of the pull rope on the movable column 531 is greater than the pulling force of the tension spring 9 on the movable column 531). At the same time, in addition to the fast flow rate, the fast rotation speed leads to a reduction in the amount of exhaust gas entering the exhaust pipe 4, so that the movable column 531 follows the adjustment of the movable seat 73 and synchronously drives the filter element 53 to move and adjust to the side close to the exhaust pipe 4, so as to reduce the contact distance between the exhaust gas and the filter element 53, so that the exhaust gas can be purified in time;

[0080] On the contrary, when the rotation speed of the rotating core 24 slows down, the speed at which the exhaust gas in the compression area enters the exhaust pipe 4 decreases, thereby reducing the swing amplitude of the guide vane 75. The adjusting arm 71 decreases with the swing angle of the guide vane 75, and the movable seat 73 moves and adjusts to the side away from the position of the connecting bolt 121 (at this time, the pulling force of the tension spring 9 on the movable column 531 is greater than the sum of the thrust of the exhaust gas on the guide vane 75 and the pulling force of the pull rope on the movable column 531). In addition, due to the slow rotation speed, the amount of exhaust gas entering the exhaust pipe 4 increases, so that the movable column 531 drives the filter element 53 to move and adjust to the side close to the external pipe 6, so as to meet the exhaust gas capacity entering the exhaust pipe 4 per unit time, so that the exhaust gas can contact the filter element 53 and be purified.

[0081] Working principle:

[0082] First, the air intake pipe 3 is connected to the exhaust outlet, and the drive motor 85 and the one-way valve are started through the PLC controller 11 to start the exhaust gas. The drive motor 85 controls the rotation of the rotating ring 82, thereby indirectly controlling the output of the gear 83, and the gear 83 drives the circular motion of the rotating core 24 in the compression mechanism. During the purification process, the compression speed can be changed by changing the output speed of the drive motor 85;

[0083] Next, the exhaust gas enters the compression mechanism. As the rotating core 24 rotates, the flow guide assembly continuously moves and adjusts between the inner walls of the fixed box 2 along with the rotating core 24. The exhaust gas enters the space between adjacent flow guide assemblies and is gradually compressed as the flow guide assemblies rotate. When passing through the outlet position, the exhaust gas flows out from the exhaust pipe 4, and then the exhaust gas is discharged from the exhaust pipe 4.

[0084] Then, during the compression process, the position of the filter element 53 in the connecting pipe 51 is changed in real time according to the rotation speed of the gear 83, that is, the compression speed, so as to cooperate with the purification process of the exhaust gas under different conditions. When the compression speed decreases, the filter element 53 is moved and adjusted to the side close to the external pipe 6. When the compression speed increases, the filter element 53 is moved and adjusted to the side close to the outlet pipe 4. The position of the filter element 53 is changed to purify the exhaust gas entering the outlet pipe 4. The exhaust gas is purified by the filter element 53 and discharged from the external pipe 6. When the filter element 53 is saturated, the filter element 53 can be replaced by replacing it from the cover plate 52.
