Description

Technical Field

[0001] The present invention relates to the field of adsorption of paint waste gas, and particularly to a low-energy consumption paint waste gas adsorption treatment device. Background Art

[0002] The waste gas generated during the paint production process mainly consists of volatile organic compounds, and may also contain other harmful substances. These waste gases pose potential hazards to the environment and human health. Nowadays, with the improvement of environmental protection awareness, it is usually necessary to treat the waste gas discharged during paint production to ensure that the waste gas meets the emission standards.

[0003] In order to avoid excessive emission of harmful gases causing environmental pollution, current paint manufacturers are equipped with catalytic neutralization equipment and activated carbon adsorption devices to purify the discharged waste gas. Although the above-mentioned treatment methods are relatively common, there are still certain drawbacks.

[0004] Firstly, during the activated carbon adsorption of waste gas, due to the limited adsorption capacity of activated carbon for waste gas, after being used for a long time, its adsorption capacity is greatly reduced. Therefore, it is necessary to regularly monitor the adsorption situation and timely replace the saturated activated carbon, which increases the maintenance workload, cannot ensure the continuity of waste gas adsorption work, and the work efficiency still needs to be improved. At the same time, when using catalytic neutralization equipment to purify waste gas, due to the poor fluidity of waste gas, it is easy to accumulate when discharging through pipelines and cannot fully contact and mix with substances such as catalysts. Therefore, the purification quality of existing catalytic neutralization equipment for waste gas still needs to be improved. Summary of the Invention

[0035] Please refer to Figure 1 and Figure 2 The auxiliary mechanism 3 includes an air delivery pipe 31 connected to the two air intake pipes 2, a trapezoidal shell 32 with an internal slope and a heat exchanger 33 installed on the trapezoidal shell 32 is fixedly provided on the outer wall of the air delivery pipe 31, a feed pipe 331 penetrating the heat exchanger 33 is connected to the trapezoidal shell 32, and a lower end face of the other end of the air delivery pipe 31 is connected to a rearward opening shaped frame 34, and a purification mechanism 4 for preliminarily purifying the exhaust gas in the air delivery pipe 31 is provided on the shaped frame 34.

[0036] Please refer to Figure 1 , Figure 4 and Figure 5 The purification mechanism 4 includes a support disc 41 rotatably arranged on the support plate 1, a driving part 42 for driving the support disc 41 to intermittently rotate is installed on the lower end surface of the support disc 41, and three purification parts 43 are arranged in a circular array above the support disc 41.

[0037] Please refer to Figure 1 , Figure 4 and Fig.10 The front end of the T-shaped frame 34 is connected to the rectangular shell 5 through the T-shaped shell 44. The interior of the rectangular shell 5 is equipped with a stirring part 56 for stirring the exhaust gas after the preliminary purification. The interior of the rectangular shell 5 is also equipped with a driving part 57 for driving the stirring part 56. The upper end of the rectangular shell 5 is connected to the heat exchanger 33 through a three-way elbow pipe 58.

[0038] Please refer to Figure 5 , Fig. 9 and Fig.10 The upper end surface of the supporting plate 1 is provided with a circular groove 11 arranged directly below the supporting disc 41. The rectangular shell 5 is fixedly arranged on the upper end surface of the supporting plate 1 by two supporting plates 12 which are symmetrical in the front-to-back direction. The bottom wall inside the rectangular shell 5 is arranged in a slope shape, and the slope height gradually decreases from the back to the front. The front inner wall of the rectangular shell 5 is fixedly provided with a mounting platform 51 in a left-right symmetrical manner. The two mounting platforms 51 are fixedly provided with ultraviolet lamp columns 52 extending in the front-to-back direction. The front inner wall of the rectangular shell 5 is provided with a plurality of mounting platforms 51, each of which is provided with a plurality of ultraviolet lamp columns 52 extending in the front-to-back direction. A rectangular block with a hollow interior is fixedly arranged on the wall and between the two ultraviolet lamp poles 52. The upper end face of the rectangular shell 5 is provided with three mounting grooves corresponding to the three joints of the three-way elbow pipe 58. Atomizing nozzles 54 connected to the joints of the three-way elbow pipe 58 are fixedly arranged inside the three mounting grooves. An air outlet pipe 55 is connected to the lower end face of the rectangular shell 5 near the front side. The upper end of the air outlet pipe 55 passes through the rectangular shell 5 and is located inside the rectangular shell 5, and the lower end of the air outlet pipe 55 passes through the supporting plate 1.

[0039] During specific operation, firstly, the two air inlet pipes 2 are connected to the exhaust pipe of the coating equipment. At the same time, a certain amount of gaseous chlorine dioxide is injected into the interior of the trapezoidal shell 32 through the feed pipe 331. As the coating equipment gradually works, the exhaust gas generated will continue to move along the air pipe 31 after entering the air pipe 31. During the movement, the heat in the exhaust gas is recovered through the heat exchanger 33. The chlorine dioxide gas is heated by the recovered heat to increase the diffusion rate of chlorine dioxide. When the exhaust gas moves to the mold frame 34, the preliminary filtration of the exhaust gas is completed through the work of the purification unit 43.

[0040] After the exhaust gas has completed the preliminary filtration, it continues to move along the T-shaped shell 44 and enters the interior of the rectangular shell 5. At this time, the stirring part 56 is started to disperse the exhaust gas inside the rectangular shell 5 to the left and right sides respectively, and while the exhaust gas is dispersed, the valve of the three-way elbow pipe 58 is opened to allow the chlorine dioxide in the heat exchanger 33 to be sprayed out through the atomizing nozzle 54. The sprayed chlorine dioxide is fully in contact with the dispersed exhaust gas, and cooperates with the ultraviolet lamp column 52 to complete further purification and disinfection of the exhaust gas. Finally, the disinfected exhaust gas is guided along the exhaust pipe 55 to the outdoor neutralization tank, and the chlorine dioxide gas is neutralized with a reducing agent such as sodium sulfite.

[0041] It should be noted that chlorine dioxide is a powerful oxidant in the form of gas, which can effectively kill bacteria, viruses and fungi. By atomizing it and bringing it into contact with waste, it can effectively disinfect harmful components in the waste gas, and heating can accelerate its diffusion, thereby improving the disinfection effect.

[0042] Please refer to Figure 1 , Figure 2 and Figure 3 The trapezoidal shell 32 is divided into a trapezoidal connecting section and an annular mounting section. The heat exchanger 33 is arranged on the outer wall of the mounting section. The trapezoidal shell 32 is provided with a stirring portion 322 for stirring the chlorine dioxide gas therein. The stirring portion 322 includes an adjusting gear 3221 rotatably arranged between the mounting section and the connecting section. The end face of the adjusting gear 3221 is provided with a plurality of air-permeable grooves along the circumferential direction. The lower end face of the adjusting gear 3221 is located inside the trapezoidal shell 32 and is fixed with two blades 3222 through a circular column along the circumferential direction. The two blades 3222 are close to the inner wall of the trapezoidal shell 32. The lower end face of the gas delivery pipe 31 is fixed with a No. 1 motor 3223 through a motor seat. The output shaft of the No. 1 motor 3223 is fixed with a driving gear 3224 that is always meshed with the adjusting gear 3221. The driving gear 3224 is rotatably connected to the trapezoidal shell 32 through a strip plate.

[0043] Please refer to Figure 4 and Figure 8The purification section 43 includes a mounting frame 432 fixedly arranged on the upper end surface of the support disc 41 through an L-shaped base 431, and an arc-shaped slider 4321 is fixedly arranged on the upper end surface and the lower end surface of the mounting frame 432. A plurality of T-shaped slide grooves 4322 are provided on the two side walls inside the mounting frame 432 along the up and down directions, and an adsorption carbon plate 433 is slidably arranged between two T-shaped slide grooves 4322 at the same height through the T-shaped slider, and an avoidance groove 434 is provided on one side of the T-shaped slide groove 4322 close to the center of the support disc 41, and a limit group 435 for limiting the movement of the adsorption carbon plate 433 is also provided between the adsorption carbon plate 433 and the mounting frame 432.

[0044] Please refer to Figure 8 The limit group 435 includes a connecting rod 4351 fixedly set on one end of the two T-shaped sliding blocks near the center of the supporting disk 41, and two adjusting plugs 4352 are installed on the outer wall of the connecting rod 4351 at the position corresponding to the avoidance groove 434, wherein the adjusting plug 4352 close to the avoidance groove 434 is fixedly connected to the connecting rod 4351, and the adjusting plug 4352 away from the avoidance groove 434 is slidably set on the outer wall of the connecting rod 4351, and a limit ring is also fixedly set on the outer wall of the connecting rod 4351, and the limit ring prevents the sliding adjusting plug 4352 from sliding out of the avoidance groove 434, and the interior of the avoidance groove 434 is symmetrically arranged with a telescopic top rod 4353 through a spring sliding manner, and the end close to the two telescopic top rods 4353 is set as a triangle and the hypotenuse is set on the side close to the adjusting plug 4352.

[0045] When the exhaust gas enters the gas pipeline 31 and recovers heat through the heat exchanger 33, the No. 1 motor 3223 is started to drive the driving gear 1 3224 to engage the adjusting gear 3221 to rotate. At the same time, a certain amount of chlorine dioxide is injected into the trapezoidal shell 32 through the feed pipe 331. When the adjusting gear 3221 rotates, it drives the two blades 3222 set on its lower end surface to rotate along the inside of the trapezoidal shell 32 and complete the stirring of the chlorine dioxide, so that the chlorine dioxide enters the connecting section of the trapezoidal shell 32 along the air permeable groove. The heat recovered by the heat exchanger 33 and the reciprocating rotating blades 3222 accelerate the diffusion of chlorine dioxide, thereby reducing the aggregation of molecules between chlorine dioxide, which is beneficial to the full contact between chlorine dioxide and exhaust gas in the later stage.

[0046] While the blade 3222 agitates chlorine dioxide inside the trapezoidal housing 32, several adsorption carbon plates 433 are manually slid into the T-shaped chutes 4322 on both sides of the mounting frame 432. At this time, the adjusting plugs 4352 provided on the adsorption carbon plates 433 first come into contact with the two telescopic push rods 4353. By pushing the two telescopic push rods 4353 respectively through the pushing of the adjusting plugs 4352, they move away from each other. When the adjusting plugs 4352 fixedly arranged on the connecting rod 4351 completely enter the avoidance groove 434, the pushing forces of the upper and lower telescopic push rods 4353 disappear and then they quickly rebound and reset to complete the limiting work of the adsorption carbon plate 433.

[0047] It should be noted that when the adsorption carbon plate 433 needs to be replaced, the adsorption carbon plate 433 is continuously pushed along the T-shaped chute 4322. At this time, the upper and lower telescopic push rods 4353 continue to push and move away from each other through the cooperation with the adjusting plugs 4352 sliding on the connecting rod 4351. After pushing the adsorption carbon plate 433 to the bottom end of the avoidance groove 434, the adsorption carbon plate 433 is pulled outwards. The upper and lower telescopic push rods 4353 drive the adjusting plugs 4352 to slide and make the two adjusting plugs 4352 close to each other. By continuing to pull the adsorption carbon plate 433, the two adjusting plugs 4352 with the same height will continuously push the corresponding telescopic push rods 4353 inside the avoidance groove 434 upwards and downwards respectively until the adsorption carbon plate 433 is pulled out of the T-shaped chute 4322.

[0048] Please refer to Figure 5 and Figure 6 As shown in the figure, on the side close to each other of the upper and lower horizontal sections of the C-shaped frame 34, arc-shaped chutes 341 are respectively provided. On the side wall of the vertical section of the C-shaped frame 34 close to the arc-shaped chute 341, a strip-shaped chute 342 is provided in the up and down direction. A pressing part 343 is slidably arranged on the strip-shaped chute 342. On the side wall of the vertical section of the C-shaped frame 34 close to the arc-shaped chute 341 and below the strip-shaped chute 342, two strip-shaped through grooves distributed in the up and down direction are also provided. Both of the two strip-shaped through grooves are communicated with the T-shaped housing 44.

[0049] Please refer to Figure 5 and Figure 6 As shown in the figure, the first driving part 42 includes a second motor 421 fixedly arranged at the bottom of the supporting plate 1 and the output shaft of which rotates through the supporting plate 1. The output shaft of the second motor 421 is rotationally connected with the C-shaped frame 34. An incomplete gear 422 is fixedly arranged on the outer wall of the output shaft of the second motor 421. A driven gear one 423 which is rotationally connected with the supporting plate 1 and meshes with the incomplete gear 422 is fixedly arranged on the lower end surface of the supporting disc 41. A ratchet 424 is fixedly arranged on the lower end surface of the driven gear one 423. In the circular groove 11, a ratchet pawl 425 which abuts against the ratchet 424 is rotatably arranged through a circular rod and a torsion spring.

[0050] Please refer to Figure 6 and Figure 7 The pressing part 343 includes an electric push rod 3431 fixedly arranged on the horizontal section above the C-shaped frame 34. The telescopic section of the electric push rod 3431 slides through the C-shaped frame 34. Inside the C-shaped frame 34 and below the electric push rod 3431, a rectangular pressing plate 3432 with a telescopic round rod on the upper end face is installed through two springs. The telescopic section of the electric push rod 3431 is fixedly connected to the telescopic round rod through a connecting plate. The rectangular pressing plate 3432 is slidably arranged in the strip-shaped chute 342 through a sliding block. The pressing part 343 further includes a sealing plug 3433 fixedly arranged inside the air delivery pipe 31 and having a tapered groove 34331 on the end face. A tapered plug 3434 that abuts against the tapered plug 3434 slides inside the tapered groove 34331. The other end of the tapered plug 3434 is fixedly connected to the telescopic round rod.

[0051] After the adsorption carbon plate 433 is installed, first start the second motor 421 to drive the incomplete gear 422 to rotate. The support disc 41 intermittently rotates through the meshing of the incomplete gear 422 and the first driven gear 423. At this time, two arc-shaped sliders 4321 on the mounting frame 432 respectively slide into two arc-shaped chutes 341 on the C-shaped frame 34, and then the C-shaped frame 34 is sealed into a whole through the mounting frame 432.

[0052] After the C-shaped frame 34 is sealed, first control the electric push rod 3431 to retract. The rectangular pressing plate 3432 slides upward along the strip-shaped chute 342 driven by the connecting plate. At this time, the tapered plug 3434 is pushed upward by the telescopic round rod and thus disengages from the sealing plug 3433. Then the waste gas enters the inside of the C-shaped frame 34 along the gap between the tapered plug 3434 and the sealing plug 3433. After a period of time, control the electric push rod 3431 to extend. The connecting plate first pulls the tapered plug 3434 downward through the telescopic round rod to complete the sealing work of the sealing plug 3433. Subsequently, continue to control the electric push rod 3431 to extend. At this time, the rectangular pressing plate 3432 slides downward along the strip-shaped chute 342 and gradually stretches the telescopic round rod. The waste gas inside the C-shaped frame 34 is pressed into the adsorption carbon plate 433 by the gradual downward pressure of the rectangular pressing plate 3432. Repeating this process can complete the intermittent release and pressing of the waste gas.

[0053] It should be noted that a ratchet 424 is arranged on the lower end face of the first driven gear 423. By the abutment of the pawl 425 and the ratchet 424, the support disc 41 can be prevented from rotating back when rotating 120 degrees, thus ensuring the stability of the rotation work.

[0054] Please refer to Fig.10The driving part 57 includes a driving gear 571 rotatably arranged inside the rectangular block, a driving shaft rotatably penetrating the rectangular block and the rectangular shell 5 is fixedly arranged on the front side wall of the driving gear 571, and the driving shaft is fixedly connected to the output shaft of the external motor. A driven gear 572 is rotatably arranged inside the rectangular block and on the left and right sides of the driving gear 571. The two driven gears 572 are arranged in an up-and-down staggered manner and are respectively meshed with the driving gear 571 for transmission.

[0055] Please refer to Fig. 9 and Fig.10 The stirring portion 56 includes a mounting rod 561 fixedly arranged on the rear side walls of a driving gear 2 571 and two driven gear 2s 572, and a plurality of mounting rings 562 distributed in the front-to-back direction are fixedly arranged on the outer wall of the mounting rod 561. The mounting rings 562 on the left and right mounting rods 561 and the mounting ring 562 on the middle mounting rod 561 are alternately arranged front to back, and a plurality of stirring blades 1 563 with the tip facing forward are fixedly arranged on the outer wall of the mounting ring 562 in a circular array, and a stirring blade 2 564 with the tip facing backward is also fixedly arranged on the outer wall of the mounting ring 562 and located between two adjacent stirring blades 1 563.

[0056] After the exhaust gas has completed the preliminary filtration, it continues to enter the interior of the rectangular shell 5 along the T-shaped shell 44, and then the external motor is started to drive the driving gear 2 571 to rotate. The driving gear 2 571 engages with the driven gear 2 572 on both sides when rotating. The two driven gears 2 572 drive the mounting rod 561 to rotate when rotating. The exhaust gas in the rectangular shell 5 is dispersed and moves to the left and right sides respectively through the centrifugal rotation of the stirring blade 1 563 and the stirring blade 2 564. At the same time, the valves of the ultraviolet lamp column 52 and the three-way elbow pipe 58 are opened, so that the chlorine dioxide in the trapezoidal shell 32 is sprayed out along the three atomizing nozzles 54, and the chlorine dioxide is fully contacted with the exhaust gas through the centrifugal rotation of the stirring blade 1 563 and the stirring blade 2 564. Subsequently, the ultraviolet lamp column 52 completes the last step of disinfection of the mixture of chlorine dioxide and exhaust gas. Finally, the disinfected exhaust gas is guided to the outdoor neutralization tank along the outlet pipe 55, and the chlorine dioxide gas is neutralized with a reducing agent such as sodium sulfite.

[0057] At the same time, when the mounting rod 561 drives the mounting ring 562 to rotate, the exhaust gas inside the rectangular shell 5 is sucked into the center position of the mounting ring 562 under the rotation of the stirring blade 1 563 and the stirring blade 2 564. The exhaust gas is dispersed by the two blades in different directions and fully contacts with the chlorine dioxide, thereby improving the disinfection quality.
