Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly to an exhaust gas washing spray tower with an anti-corrosion structure. Background Art

[0002] An exhaust gas washing spray tower is a common industrial waste gas treatment device, mainly used to remove pollutants in waste gas, such as particulate matter, acidic gases, and organic compounds, etc. Its working principle is to purify the gas through the contact between the spray liquid and the waste gas, using physical absorption, chemical reaction, or dissolution; an exhaust gas washing spray tower usually consists of a tower body, a spray system, a packing layer, a demister, and inlets and outlets. The waste gas enters from below and flows upward, while the spray liquid of the spray system is sprayed downward and contacts the rising gas reversely. The pollutants in the waste gas are captured by the spray liquid droplets or undergo chemical reactions, and the purified gas is dehydrated by the demister and then discharged upward.

[0003] The packing layer inside the existing exhaust gas washing spray tower usually consists of a grille and packing placed on the grille. After the spray tower is used for a long time, particulate matter and impurities in the waste gas adhere to the surface of the packing and gradually accumulate to cause packing blockage. Therefore, regular cleaning or replacement is required. The existing cleaning and replacement method is to hang a material bag on the observation window and manually take out the packing on the horizontally installed grille from the tower body by hand. However, due to the large internal volume of the spray tower and the large filling amount of the packing, the manual taking-out speed is too slow, and there are problems of inconvenient cleaning and replacement.

[0009] Preferably, a fixed block is installed on the inner wall of the tower body below the connecting block. A turning shaft penetrates between the fixed block and the connecting block. A limiting block is installed on the inner wall of the rear side of the tower body below the rectangular grille. The rectangular grille is rotatably connected to the tower body through the turning shaft.

[0010] Preferably, the traction assembly includes a traction rope at the rear side of the upper rectangular grille and a connecting rope connected between the two packing purification assemblies. The upper end of the traction rope extends out from the rear side wall of the tower body and is connected to a winch. A guide wheel is installed on the rear side wall of the tower body above the winch. The upper end of the connecting rope is connected to the upper rectangular grille, and the lower end of the connecting rope is connected to the rear plate of the lower one.

[0011] Preferably, the material spreading assembly includes a fixed rod installed outside the third pin shaft. Connecting rods are connected to both the left and right sides of the fixed rod.

[0013] Preferably, the spray assembly includes a spray pipe installed on the inner wall of the tower body. A nozzle is connected to the bottom of the spray pipe. A spray valve is installed on the part of the spray pipe extending out of the tower body. One ends of the two spray pipes are jointly connected to a liquid inlet pipe. A circulating pump is connected to the bottom of the liquid inlet pipe. The water inlet of the circulating pump is connected to a circulating pipe. The spray pipe communicates with a circulating water tank through the liquid inlet pipe and the circulating pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. For this waste gas washing spray tower with an anti-corrosion structure, by setting a packing purification assembly, the rectangular grille is rotatably connected to the fixed block through the connecting block and the turning shaft, so that the rectangular grille can drive the blocked packing inside to turn upwards. At this time, the rectangular grille is in an inclined state, and the packing inside flows forward. By applying a forward pulling force to the front plate, the two front plates rotate to form an angle and protrude forward, forming a triangular gap with the rectangular grille. At the same time, the front plate pulls the side plate to rotate relative to the rear plate through the second pin shaft, and the two side plates rotate around the first pin shaft and approach each other, pushing the packing on the rectangular grille to discharge from the gap below the front plate, realizing the effect that the blocked packing can be automatically discharged from the rectangular grille during cleaning, without manual scraping, which not only reduces the labor burden of workers, but also speeds up the speed of removing the packing from the spray tower.

[0015] 2. For this waste gas washing spray tower with an anti-corrosion structure, by setting a traction mechanism, the winch drives the traction rope to wind up, and the traction rope pulls the upper rectangular grille upwards, so that the upper rectangular grille rotates upwards by 15° around the turning shaft. At the same time, the upper rectangular grille pulls the lower rear plate to flip through the connecting rope at the bottom, and the rear plate drives the lower rectangular grille to flip, realizing the effect of synchronously flipping the two packing purification assemblies driven by the traction rope, which is convenient for subsequent discharging of the packing in the two packing purification assemblies at the same time.

[0016] 3. For this waste gas washing spray tower with an anti-corrosion structure, by setting a grille plate, the triangular gap between the front plate and the rectangular grille is in an open state when the packing is discharged. When the washed packing or new packing is poured back into the spray tower, the grille plate is pulled out of the groove through the handle until the grille plate seals the triangular gap. The front plate protrudes forward as a guiding structure for packing feeding, making it more convenient for the packing to be discharged or fed.

[0017] 4. For this waste gas washing spray tower with an anti-corrosion structure, by setting a spreading component, when the washed packing or new packing is poured back into the spray tower, to avoid a large amount of packing accumulating in front of the rectangular grille, by pushing the front plate to expand backward, the front plate drives the third pin shaft to move backward, the third pin shaft drives the fixed rod to move backward, and the fixed rod drives a plurality of material pushing rods to move backward, pushing the packing accumulated in the front to move backward, so that the packing is evenly spread on the rectangular grille, realizing the effect of assisting in spreading the packing.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "equipped with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] As Figures 1 to 6 shown, the exhaust gas washing spray tower with an anti-corrosion structure in this embodiment includes a tower body 1, a liquid storage tank 2 opened inside the tower body 1, an air inlet pipe 3 installed on one side wall of the tower body 1, and an air outlet pipe 7 installed on the top of the tower body 1. The cross-section of the tower body 1 is rectangular. Inside the tower body 1 above the liquid storage tank 2, two packing purification components 4 are installed for purifying exhaust gas. Above the two packing purification components 4, spray components 5 are installed inside the tower body 1 to enable the sprayed droplets to fully mix and contact with the exhaust gas and then undergo a chemical reaction. Inside the inner wall of the tower body 1 below the air outlet pipe 7, a demister 6 is installed to remove the spray liquid entrained in the purified gas. An anti-corrosion lining 8 is laid on the inner wall of the tower body 1. The material of the anti-corrosion lining plate is polytetrafluoroethylene, which is an anti-corrosion structure inside the tower body 1 for anti-corrosion of the inner wall of the tower body 1. One side of the tower body 1 away from the air inlet pipe 3 is connected to a circulation water tank 9. The inner cavity of the circulation water tank 9 is communicated with the liquid storage tank 2. The spray liquid sprayed by the spray system falls into the liquid storage tank 2 after reacting with the exhaust gas, and then the spray liquid flows into the circulation water tank 9. A medicine adding cylinder is installed on one side of the circulation water tank 9 for reconfiguring the pH value of the spray liquid, and a sewage discharge pipe is provided. A detection port 10 is penetrated and opened on the side wall of the tower body 1 in front of the packing purification component 4. A sealing window 11 is movably inserted into the detection port 10. Both the detection port 10 and the sealing window 11 are rectangular, and the width dimension of the detection port 10 needs to meet the requirement that the front plate 45 of the packing purification component 4 extends in when it is flipped. When the sealing window 11 is in the closed state, the inner wall of it presses the front side wall of the front plate 45 of the packing purification component 4 to maintain the stability of the rectangular frame and prevent the packing from piling up towards the front and pushing the front plate 45 to protrude forward; The filler purification component 4 includes a rectangular grille 41. At the rear edge of the upper surface of the rectangular grille 41, a rear plate 42 is vertically connected. On both the left and right sides of the rear plate 42, side plates 43 are vertically connected. On the front sides of both side plates 43, front plates 45 are vertically connected. A first pin shaft 44 is penetrated between the rear sides of the two side plates 43 and the rear plate 42 for connecting the side plates 43 and the rear plate 42. A second pin shaft 46 is penetrated between the front sides of the two side plates 43 and the two front plates 45 respectively for connecting the side plates 43 and the front plates 45. Torsion springs 47 are sleeved outside the first pin shaft 44 and the second pin shaft 46. When an included angle is formed between the two front plates 45 and protrudes forward, the torsion springs 47 generate a resilience force. When the pulling force of the staff on the front plates 45 is lost, the front plates 45 are pulled back to their original positions by the rebound of the torsion springs 47. A third pin shaft 48 is penetrated between the two front plates 45, and a feeding component 49 is installed outside the third pin shaft 48 between the two front plates 45 for spreading the added filler.

[0024] Specifically, the rear plate 42 is connected to the two side plates 43 and the two front plates 45 to form a rectangular frame. The rectangular frame cooperates with the rectangular grille 41 to provide a stable filling area for the filler. When the rectangular grille 41 is flipped, the filler filled inside it can be driven to move. The filler is filled between the rectangular frame and the rectangular grille 41. The rear plate 42 is fixedly connected to the rectangular grille 41. The bottoms of the side plates 43 and the front plates 45 are slidably connected to the rectangular grille 41. The two side plates 43 can approach each other relative to the rectangular grille 41. The approaching here means that the side plates 43 make an arc movement around the first pin shaft 44. The two front plates 45 can move forward relative to the rectangular grille 41. The movement here means that the two front plates 45 rotate relative to the third pin shaft 48 to form an included angle.

[0025] Furthermore, the rear sides of the side plates 43 are rotationally connected to the rear plate 42 via the first pin shaft 44, and the front sides of the side plates 43 are rotationally connected to the front plates 45 via the second pin shaft 46. When the front plates 45 rotate and drive the two side plates 43 to approach each other via the second pin shaft 46, at this time, the side plates 43 extrude the filler on the rectangular grille 41, and push the filler on the rectangular grille 41 to discharge from the gap below the front plates 45. The side plates 43 are used to block the left and right sides during the filling of the filler and also play a positive promoting role during the discharging of the filler.

[0026] Furthermore, a groove 411 is provided on the front side of the rectangular grille 41, and a grille plate 412 is slidably connected inside the groove 411. A handle 413 is connected to the front side wall of the grille plate 412, which serves as a fulcrum for the front side wall of the grille plate 412, so that a manual hand can be inserted into the groove 411 and the grille plate 412 can be pulled out via the handle 413. A connecting block 414 is connected to the front edge of the lower surface of the rectangular grille 41, and a traction assembly 15 is commonly connected to the rear sides of the two rectangular grilles 41 for traction driving the filler purification assembly 4 to flip. A groove corresponding to the rectangular grille 41 is provided on the grille plate 412, and the groove is an existing structure of the rectangular grille 41, so as to facilitate the exhaust gas and spray liquid to pass through the rectangular grille 41. The grille plate 412 is movably connected to the rectangular grille 41 through the groove 41. After the grille plate 412 is fully inserted into the groove 411, the groove inside it coincides with the groove on the rectangular grille 41, so as to ensure that the rectangular grille 41 will not be blocked.

[0027] Furthermore, a fixed block 12 is installed on the inner wall of the tower body 1 below the connecting block 414 for installing the connecting block 414, and a flip shaft 13 is provided between the fixed block 12 and the connecting block 414. A limit block 14 is installed on the inner wall of the rear side of the tower body 1 below the rectangular grid 41. The limit block 14 is located on the inner wall of the tower body 1 on the opposite side of the fixed block 12, and is used for bottom support when the rectangular grid 41 is in a horizontal state. The rectangular grid 41 is rotatably connected to the tower body 1 via the flip shaft 13. After the rectangular grid 41 is flipped relative to the tower body 1 via the flip shaft 13, the rectangular grid 41 drives the blocked filler inside it to move. At this time, the rectangular grid 41 is in an inclined state, so that the filler inside has a tendency to flow toward the front.

[0028] Furthermore, the traction assembly 15 includes a traction rope 152 at the rear side of the upper rectangular grid 41 and a connecting rope 151 connected between the two packing purification assemblies 4. The upper end of the traction rope 152 extends from the rear side wall of the tower body 1 and is connected to a winch 154. A detachable rubber seal can be installed at the gap between the traction rope 152 and the tower body 1 to prevent exhaust gas leakage. When the traction rope 152 is used later, the seal needs to be removed. The winch 154 is installed on the rear side wall of the tower body 1. The winch 154 is an existing structure, including a winch frame, a rope winding roller, a motor and a limit assembly. The upper end of the traction rope 152 is guided by the guide wheel 153 and then wound on the rope winding roller. The traction rope 152 is driven by a winch 154 to reel in or unreel. A guide wheel 153 is installed on the rear side wall of the tower body 1 above the winch 154 for guiding the traction rope 152. The upper end of the connecting rope 151 is connected to the upper rectangular grid 41, and the lower end of the connecting rope 151 is connected to the lower rear plate 42. When the winch 154 drives the traction rope 152 to reel in, the traction rope 152 pulls the upper rectangular grid 41 to rotate upward 15° around the flip axis 13. At the same time, the upper rectangular grid 41 pulls the lower rear plate 42 to flip through the bottom connecting rope 151, and the two filler purification components 4 are driven to flip synchronously by the traction of the traction rope 152.

[0029] Further, the material spreading assembly 49 includes a fixing rod 491 installed outside the third pin shaft 48. The fixing rod 491 is in the shape of a rectangular rod, and the front side of the fixing rod 491 is annularly installed outside the third pin shaft 48. Connecting rods 492 are connected to both the left and right sides of the fixing rod 491. Pushing rods 493 are perpendicularly connected to both the connecting rod 492 and the bottom of the fixing rod 491. The fixing rod 491 and the connecting rods 492 are connected to form a "soil" shape, increasing the coverage range of the pushing rods 493. The pushing rods 493 are inserted into the filler. When the front plate 45 moves backward, it drives the fixing rod 491 to move backward. The fixing rod 491 drives a plurality of pushing rods 493 to move backward, pushing the filler piled up on the front side to move backward, so that the filler is evenly spread on the rectangular grid 41, achieving the effect of assisting in spreading the filler and avoiding manual spreading.

[0030] Further, the length dimension of the front plate 45 is half of that of the side plate 43. One front plate 45 is fixedly connected to the third pin shaft 48, and the other front plate 45 is rotatably connected to the third pin shaft 48. When the front plate 45 is subjected to a forward pulling force, the two front plates 45 move forward and form an angle. The third pin shaft 48 drives the fixing rod 491 to move. The front side of the fixing rod 491 is fixedly connected to the third pin shaft 48, ensuring that the fixing rod 491 only moves in a straight line back and forth and will not be skewed due to relative rotation with the third pin shaft 48.

[0031] Furthermore, the spraying assembly 5 includes a spraying pipe 51 installed on the inner wall of the tower body 1. Nozzles 52 are connected to the bottom of the spraying pipe 51. The spraying pipes 51 are evenly distributed in the tower body 1, and the spraying liquid sprayed by the nozzles 52 covers the whole circumference. A spraying valve 53 is installed on the part of the spraying pipe 51 extending out of the tower body 1. One ends of two spraying pipes 51 are commonly connected to a liquid inlet pipe 54. A circulating pump 55 is connected to the bottom of the liquid inlet pipe 54. The water inlet of the circulating pump 55 is connected to a circulating pipe 56. The spraying pipe 51 communicates with the circulating water tank 9 through the liquid inlet pipe 54 and the circulating pipe 56. The circulating pump 55 feeds the spraying liquid in the circulating water tank 9 into the liquid inlet pipe 54 through the circulating pipe 56. After the spraying valve 53 is opened, the spraying liquid enters the spraying pipe 51 and finally sprays out from the nozzles 52, forming a spraying layer for spraying and purifying the waste gas.

[0032] The usage method of this embodiment is as follows: When the user actually uses the waste gas washing spray tower to purify waste gas, first, the waste gas is introduced into the tower body 1 from the air inlet pipe 3 by borrowing a fan. At the same time, the circulating pump 55 introduces the spray liquid in the circulating water tank 9 into the liquid inlet pipe 54 from the circulating pipe 56. After the spray valve 53 is opened, the spray liquid enters the spray pipe 51 and finally sprays out from the spray head 52. The spray liquid drops on the packing, and the spray liquid adheres to the surface of the packing in a thin film state. Then the waste gas enters the tower body 1 and rises, passes through the rectangular grid 41 and enters the packing layer. The waste gas fully contacts the spray liquid on the surface of the packing and undergoes a large amount of mass exchange. The reacted waste gas continues to rise and contacts the spray liquid sprayed by the spray pipe 51 in a reverse direction. The spray liquid forms droplets and is fully mixed and contacted with the waste gas, and a chemical reaction continues to occur. The treated gas rises, and after the entrained spray liquid is absorbed by the demister 6, it is discharged from the air outlet pipe 7. After the packing has been treating waste gas for a long time, the particulate matter and impurities in the waste gas adhere to the surface of the packing. After gradually accumulating, the packing becomes blocked. At this time, the circulating pump 55 is turned off to stop spraying, and the air inlet pipe 3 is closed. Then, the staff opens the two sealing windows 11 and starts the winch 154. The winch 154 drives the traction rope 152 to wind up. The traction rope 152 pulls the upper rectangular grid 41 upward, causing the upper rectangular grid 41 to rotate upward by 15° around the turning shaft 13. At the same time, the upper rectangular grid 41 pulls the rear plate 42 below to flip through the connecting rope 151 at the bottom. The rear plate 42 drives the lower rectangular grid 41 to flip. At this time, both rectangular grids 41 are in an inclined state, and the front plate 45 extends out from the detection port 10. The internal packing flows forward. Then, the staff places a material bag below the detection port 10 and applies a forward pulling force to the front plate 45, causing the two front plates 45 to rotate to form an angle and protrude forward. A triangular gap is formed between the front plate 45 and the rectangular grid 41. At the same time, the front plate 45 pulls the side plate 43 to rotate relative to the rear plate 42 through the second pin shaft 46. The two side plates 43 rotate around the first pin shaft 44 and approach each other, pushing the packing on the rectangular grid 41 to discharge from the gap below the front plate 45 and fall into the material bag. After cleaning or replacing the packing, the winch 154 unwinds the rope to make the rectangular grid 41 rotate back to its original position. Then, the grid plate 412 is pulled out from the groove 411 through the handle 413 until the grid plate 412 blocks the triangular gap below the front plate 45. Then, the cleaned or new packing is poured into the front plate 45. The front plate 45 protrudes forward as a guiding structure for packing feeding. At this time, a large amount of packing accumulates in front of the rectangular grid 41. Then, the front plate 45 is pushed backward to expand. The front plate 45 drives the third pin shaft 48 to move backward. The third pin shaft 48 drives the fixed rod 491 to move backward. The fixed rod 491 drives a plurality of material pushing rods 493 to move backward, pushing the packing accumulated in the front to move backward, which is conducive to the packing being evenly spread on the rectangular grid 41. After the packing is filled.
