Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas purification equipment, in particular to a waste gas emission purification equipment and purification process for automobile shock-resistant expansion adhesive production line. BACKGROUND

[0002] The automobile shock-resistant expansion adhesive production mainly involves processes such as rubber mixing, vulcanization and drying. These production processes will produce waste gas that damages the environment, which needs to be purified by waste gas purification equipment. After the waste gas treatment meets the standards, it can be discharged. The existing waste gas purification equipment includes a spray tower. The tower body of the spray tower is a vertical cylinder. The bottom is provided with a filler support plate. The fillers are placed on the support plate in a random or whole pile manner. A filler pressing plate is installed above the fillers to prevent the fillers from being blown by the rising gas flow. Liquid is sprayed from the spray assembly at the top of the tower to the fillers and flows down along the filler surface. The waste gas is sent from the bottom of the tower and continuously passes through the gaps of the filler layer in countercurrent with the liquid. On the surface of the fillers, the gas-liquid two phases are in close contact for mass transfer. Then the waste gas passes through the spray area and contacts the spray liquid again to complete the purification of the waste gas. The purified gas passes through the demisting layer and is discharged from the top of the tower.

[0003] However, in the process of using the traditional spray tower, the liquid sprayed from the spray assembly flows from one filler to another. For the whole filler layer, the liquid flow direction can be considered random. However, for the fillers close to the tower wall, the liquid flows along the tower wall after passing through the contact point of the filler and the tower wall. This part of the liquid flow returns to the filler layer. Therefore, the liquid near the tower wall flows towards the tower wall, which easily causes the liquid in the filler layer to flow towards the tower wall. After flowing for a distance, the liquid flow at the center of the filler layer decreases relatively. The liquid flow sprayed by the spray assembly tends to converge towards the tower wall, which is called "tower wall effect". At the same time, part of the liquid sprayed by the conical spray assembly directly sprays onto the inner wall of the tower body, causing the liquid flow at the top of the filler layer and the part of the liquid flow passing through the filler layer to flow down along the tower wall. This part of the liquid flow is difficult to effectively contact with the waste gas, which reduces the utilization efficiency of the sprayed liquid and the efficiency of the overall waste gas purification.

[0022] Two connecting plates 26 are fixedly connected to the top of the inner side of the tower body 1, and a fixed cylinder 10 is fixedly connected between the two connecting plates 26, as shown in Figure 6 , One side of the bottom of the fixed cylinder 10 is rotatably provided with a transmission shaft 11, the transmission shaft 11 is rotatably sleeved with the pressing plate 6, the shaft body of the transmission shaft 11 is fixedly sleeved with a rotating seat 18, the rotating frame 7 is composed of vertical plates and annular plates connected longitudinally and transversely, the rotating seat 18 is fixedly installed at the center position corresponding to the rotating frame 7, that is, the axis of the transmission shaft 11 is collinear with the rotating center line of the rotating frame 7, the rotating seat 18 is rotatably sleeved with the corresponding support plate 5, and a driving mechanism is further included.

[0023] The driving mechanism is used for driving the transmission shaft 11 to rotate. Specifically, the driving mechanism includes a rotating shaft 12, as shown in Figure 7 , The rotating shaft 12 is rotatably connected with the fixed cylinder 10, a plurality of blades 13 are fixedly connected to the outer side of the rotating shaft 12, the plurality of blades 13 and the rotating shaft 12 form an impeller, one side of the fixed cylinder 10 is fixedly connected with a liquid inlet pipe 16, the other side of the fixed cylinder 10 is fixedly connected with a connecting pipe 17, the impeller divides the cavity of the fixed cylinder 10 into a plurality of parts, the liquid inlet pipe 16 is in communication with a liquid supply mechanism, the liquid enters the fixed cylinder 10 from the liquid inlet pipe 16 and then flows out through the connecting pipe 17, the liquid flow can drive the impeller to rotate, one end of the connecting pipe 17 is connected with the spraying assembly 4, the bottom of the rotating shaft 12 is fixedly sleeved with a transmission gear 14, the top of the transmission shaft 11 is fixedly sleeved with a connecting gear 15, and the connecting gear 15 and the transmission gear 14 are in meshing relationship.

[0024] Unlike liquid driving, the driving mechanism can also be provided as a driving motor with an output end in transmission connection with the transmission shaft 11, and the number of filler layers is at least one, as shown in Figure 3 , The inner side of the tower body 1 movably provides the rotating frame 7, the number of the rotating frame 7 is set to be matched with the number of the filler layers, that is, a single filler layer is located between two adjacent rotating frames 7, and the number of the rotating seat 18 is set to be matched with the number of the rotating frame 7, as shown in Figure 5The top surface of the rotating frame 7 is provided with a flow guide groove 8, which is used to collect the wall flow and guide the wall flow to the center of the tower body 1. The inner wall bottom surface of the flow guide groove 8 is provided as a horizontal plane. The bottom of the inner wall of the flow guide groove 8 is provided with a liquid outlet hole 9, which is used to guide the liquid collected in the flow guide groove 8 out from the bottom of the rotating frame 7.

[0025] The number of the liquid outlet holes 9 is set to be several, and the several liquid outlet holes 9 are arranged in a radial manner with uniform intervals. Referring to Figure 3 The top of the rotating frame 7 is provided with a flow guide ring 25, which is fixedly installed on the inner side of the tower body 1 and located at the top of all the filler layers. Referring to Figure 8 The flow guide ring 25 at the bottom of the filler layer is fixedly connected with the support plate 5, and a gap is left between the flow guide ring 25 and the rotating frame 7 to avoid contact friction during the rotation of the rotating frame 7. The flow guide ring 25 is used to guide the wall flow to the flow guide groove 8.

[0026] In use, the liquid for purifying the exhaust gas is pumped into the liquid inlet pipe 16 by the liquid supply mechanism. The liquid flows through the liquid inlet pipe 16, the fixed cylinder 10, enters the connecting pipe 17, and is sprayed out through the spraying assembly 4. The liquid flow drives the impeller in the fixed cylinder 10 to rotate. The rotation of the rotating shaft 12 of the impeller drives the transmission gear 14 to rotate. The rotation of the transmission gear 14 drives the connected gear 15 to rotate at a reduced speed. The connected gear 15 drives the transmission shaft 11 to rotate, and the transmission shaft 11 drives the rotating seat 18 to rotate, thereby driving the corresponding several rotating frames 7 to rotate slowly. The liquid flow on the inner wall of the tower body 1 flows and falls under the action of gravity.

[0027] When passing through the flow guide ring 25, the liquid flows and falls along the top surface and the side wall of the flow guide ring 25 into the flow guide groove 8 of the rotating frame 7. The liquid accumulates in the flow guide groove 8 and flows along the flow guide groove 8 to the center of the rotating frame 7. The liquid flows out of the liquid outlet hole 9 and falls from the liquid outlet hole 9. At the same time, the rotating frame 7 rotates, changing the horizontal position of the liquid outlet hole 9 and increasing the distribution area of the liquid flowing out of the liquid outlet hole 9 on the plane, so that the liquid flow on the inner wall of the tower body 1 can be redistributed to fall near the center of the tower body 1, so that the liquid can effectively contact the exhaust gas, improve the utilization efficiency of the spraying liquid, and at the same time, the redistributed liquid can fall to each position on the radial and circumferential of the bottom filler layer. Compared with the wall flow contacting the edge part of the filler layer, the uniformity of the contact distribution of the redistributed liquid and the filler layer is improved, ensuring that the liquid forming the wall flow part can participate in the flow on the surface of the filler in the filler layer, and ensuring the overall purification efficiency.

[0028] When the wall flow of the tower body 1 is small, the liquid flow on the flow guide groove 8 flows out of the liquid outlet hole 9 near the outer side of the tower body 1, so that the liquid outlet hole 9 on the inner side obtains less or even no liquid flow.

[0029] In example two, as Figures 1-9On the basis of the first embodiment, the bottom of the inner wall of the flow guide groove 8 is slidably provided with a plurality of movable plates 20 for closing the liquid outlet holes 9. The plurality of movable plates 20 are arranged in a radial manner, and the movable plates 20 can slide in the radial direction relative to the rotating frame 7. The top surface of the movable plate 20 is flush with the bottom surface of the inner wall of the flow guide groove 8. The movable plate 20 is provided with a plurality of communication holes 21. The plurality of communication holes 21 are arranged in a uniform manner at intervals. The number of communication holes 21 is matched with the number of liquid outlet holes 9 closed by the corresponding movable plate 20. Referring to Figure 8 One side of the movable plate 20 is fixedly connected with an adjusting spring 24.

[0030] The adjusting spring 24 is used to push the movable plate 20 towards the center of rotation of the rotating frame 7, so that the position of the communication hole 21 is staggered with the horizontal position of the liquid outlet hole 9. When the adjusting spring 24 is in a contracted state, the position of the communication hole 21 corresponds to the position of the liquid outlet hole 9, so that the communication hole 21 connects the flow guide groove 8 and the liquid outlet hole 9. Referring to Figure 9 The bottom of the rotating seat 18 is fixedly provided with an adjusting plate 19. Referring to Figure 10 The outer wall surface of the adjusting plate 19 changes in a wave shape, so that the distance between the outer wall of the adjusting plate 19 and the axis of the transmission shaft 11 changes in a reciprocating manner. One side of the movable plate 20 is fixedly connected with a connecting rod 22. One side of the bottom of the connecting rod 22 is rotatably provided with an adjusting wheel 23. The adjusting wheel 23 is used to abut against the side wall of the adjusting plate 19 in a rolling contact manner. The distance from the center of the rotating frame 7 to the liquid outlet hole 9 corresponding to a single rotating frame 7 is different, so that the radii of rotation of different liquid outlet holes 9 are different.

[0031] During the rotation of the rotating frame 7, the rotating frame 7 drives the movable plate 20 to rotate around the axis of the transmission shaft 11. The movable plate 20 drives the connecting rod 22 to rotate. The adjusting spring 24 pushes the movable plate 20. The connecting rod 22 drives the adjusting wheel 23 to keep abutting against the outer wall of the adjusting plate 19 while the adjusting wheel 23 rotates along the adjusting plate 19. The distance between the adjusting wheel 23 and the axis of the transmission shaft 11 changes in an alternating manner. The elastic force of the adjusting spring 24 drives the adjusting wheel 23 to move the connecting rod 22 in the radial direction of the rotating frame 7, and the connecting rod 22 drives the movable plate 20 to move reciprocally.

[0032] When the movable plate 20 is close to the adjusting plate 19, the movable plate 20 drives the communication hole 21 to move away from the top of the liquid outlet hole 9, and the movable plate 20 keeps closing the liquid outlet hole 9. At this time, the wall flow falls into the guide groove 8 and accumulates in the guide groove 8, so that the liquid in the guide groove 8 at the top of the liquid outlet hole 9 is accumulated. When the movable plate 20 moves relatively far away from the adjusting plate 19, the communication hole 21 moves to the position corresponding to the liquid outlet hole 9, and the liquid in the guide groove 8 flows out of the liquid outlet hole 9 through the communication hole 21 while the rotating frame 7 rotates, completing the redistribution of the wall flow after collection, avoiding the concentration of the wall flow received by the filler layer from the liquid outlet hole 9 on the outside, and further improving the uniformity of the wall flow redistributed by the liquid outlet hole 9. In combination with the different rotating radii corresponding to different liquid outlet holes 9, the uniformity of the liquid flow distributed in the radial direction of the liquid outlet hole 9 can be improved in the case of small flow of wall flow.

[0033] In example three, as Figures 1-10 On the basis of example one, the inner side of the transmission shaft 11 is sleeved with a limiting rod 27, the top surface of the limiting rod 27 is in communication with the cavity of the fixed cylinder 10, the cross section of the limiting rod 27 is T-shaped, the limiting rod 27 can axially slide without being separated from the transmission shaft 11, the one end of the rod body of the limiting rod 27 is movably sleeved with a return spring 28, the return spring 28 is used to push the limiting rod 27 to extend out of the transmission shaft 11, the water pressure in the fixed cylinder 10 acts on the top surface of the limiting rod 27, the elastic force of the return spring 28 acts on the bottom surface of the wide part of the limiting rod 27, a through hole is formed in one side of the top of the shaft body of the transmission shaft 11, the through hole is used to satisfy that the pressure in the movable cavity of the bottom of the limiting rod 27 can change, the rod body of the limiting rod 27 is fixedly sleeved with a limiting block 29, the number of the limiting block 29 is matched with the number of the rotating frame 7, and reference can be made to Figure 9 The one side of the rod body of the connecting rod 22 is fixedly connected with a moving rod 31, the outer side of the moving rod 31 is movably sleeved with a fixed block 30, and the fixed block 30 is fixedly connected with the transmission shaft 11.

[0034] When the purification equipment needs to process a large amount of waste gas in a short time, the amount of liquid pumped into the liquid inlet pipe 16 is increased, so that the amount of liquid sprayed by the spraying assembly 4 of the purification equipment remains in a large flow state. At this time, the liquid pressure in the fixed cylinder 10 increases, and the liquid flow along the tower wall also increases, and the rotating frame 7 keeps rotating. The connecting rod 22 moves back and forth in the radial direction of the rotating frame 7 to drive the moving rod 31 to move relative to the fixed block 30. The liquid pressure in the fixed cylinder 10 pushes the limiting rod 27 to retract into the transmission shaft 11 against the elastic force of the return spring 28.

[0035] When the connecting rod 22 drives the moving rod 31 away from the transmission shaft 11, the moving rod 31 moves horizontally away from the bottom of the limiting block 29, the limiting rod 27 moves to drive the limiting block 29 to move to one end of the moving rod 31, and the adjusting spring 24 is driven to push the moving rod 31 to move close to the transmission shaft 11, so as to limit the moving plate 20 to move close to the center of the rotating frame 7, and the communication hole 21 and the liquid outlet hole 9 always keep the corresponding state, so that the opening degree of the liquid outlet hole 9 is kept maximum, the wall flow flowing into the guide groove 8 under the large flow state is discharged through each liquid outlet hole 9, the average opening degree of the liquid outlet hole 9 in a period of time is increased to be able to meet the increased wall flow, and the liquid accumulation in the guide groove 8 is avoided to overflow from the top, so as to further improve the reliability and adaptability of the use of the purification equipment.

[0036] The automobile anti-seismic expansion adhesive production line waste gas emission purification process comprises the following steps: S1: the waste gas is introduced from the bottom of the tower body 1, and liquid is supplied to the spray assembly 4, so that the spray assembly 4 sprays the liquid for purifying the waste gas to the bottom of the tower body 1; S2: the driving mechanism drives the transmission shaft 11 to rotate, and the transmission shaft 11 drives the corresponding rotating frame 7 to rotate, and at the same time, the liquid flow on the inner wall of the tower body 1 falls into the guide groove 8 through the outer wall of the guide ring 25; S3: the liquid flows along the guide groove 8 to the center of the rotating frame 7, and the liquid is discharged from the liquid outlet hole 9 when flowing through the liquid outlet hole 9, and the rotating frame 7 rotates to change the horizontal position of the liquid outlet hole 9, so that the liquid discharged from the liquid outlet hole 9 falls along the corresponding annular distribution in the horizontal plane; S4: the waste gas passes through the cavity of the tower body 1, contacts the liquid on the surface of the filler after the liquid is distributed by the liquid outlet hole 9 and the spray assembly 4, and the waste gas contacts the liquid discharged from the liquid outlet hole 9 and the spray assembly 4, so as to purify the waste gas; S5: the purified gas is discharged from the top of the tower body 1 after demisting, and the liquid used for purification is recycled from the bottom of the tower body 1.
