Description

Technical Field

[0001] The present invention relates to the field of paint waste gas adsorption, 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 emissions of harmful gases causing environmental pollution, today's paint production plants will set up catalytic neutralization equipment and activated carbon adsorption devices to purify the discharged waste gas. Although the above several 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

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-10 This application is described in further detail.

[0034] Please refer to Figure 1 A low-energy paint waste gas adsorption treatment device includes a support plate 1, on which are mounted two air intake pipes 2 connected to the exhaust pipes of external paint equipment, and the two air intake pipes 2 are provided with auxiliary mechanisms 3 for cooperating with the air intake pipes 2 to transport the waste gas.

[0035] Please refer to Figure 1 and Figure 2 , the auxiliary mechanism 3 includes an air delivery pipe 31 connected to two intake pipes 2. A trapezoidal housing 32 with an internal slope is fixedly arranged on the outer wall of the air delivery pipe 31, and a heat exchanger 33 is installed on the trapezoidal housing 32. A feed pipe 331 penetrating through the heat exchanger 33 is connected to the trapezoidal housing 32. The lower end surface of the other end of the air delivery pipe 31 is connected with a U-shaped frame 34 with an opening facing backward. A purification mechanism 4 for preliminarily purifying the waste gas in the air delivery pipe 31 is cooperatively arranged on the U-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 one 42 for driving the support disc 41 to rotate intermittently is installed on the lower end surface of the support disc 41. Three purification parts 43 are arranged in a circumferential array above the support disc 41.

[0037] Please refer to Figure 1 , Figure 4 and Figure 10 , the front end of the U-shaped frame 34 is connected with a rectangular housing 5 through a T-shaped housing 44. An agitating part 56 for dispersing the waste gas after preliminary purification is installed inside the rectangular housing 5. A driving part two 57 for driving the agitating part 56 to work is also installed inside the rectangular housing 5. The upper end of the rectangular housing 5 is connected to the heat exchanger 33 through a three-way elbow pipe 58.

[0038] Please refer to Figure 5 , Figure 9 and Figure 10 , a circular groove 11 is formed on the upper end surface of the support plate 1 and is located directly below the support disc 41. The rectangular housing 5 is fixedly arranged on the upper end surface of the support plate 1 through two symmetrically arranged front and rear support plates 12. The bottom wall inside the rectangular housing 5 is in a slope shape, and the slope height gradually decreases from back to front. The front side inner wall of the rectangular housing 5 is fixedly arranged with mounting platforms 51 in a left-right symmetric manner. Ultraviolet lamp columns 52 extending in the front and rear directions are fixedly arranged on both of the mounting platforms 51. A rectangular block with a cavity inside is also fixedly arranged on the front side wall inside the rectangular housing 5 and is located between the two ultraviolet lamp columns 52. Three installation through grooves corresponding to the three joints of the three-way elbow pipe 58 are formed on the upper end surface of the rectangular housing 5. Atomizing nozzles 54 connected to the joints of the three-way elbow pipe 58 are respectively fixedly arranged inside the three installation through grooves. An air outlet pipe 55 is connected to the lower end surface of the rectangular housing 5 near the front side. The upper end of the air outlet pipe 55 penetrates through the rectangular housing 5 and is located inside the rectangular housing 5, and the lower end of the air outlet pipe 55 penetrates through the support plate 1.

[0039] During specific operation, the two air inlet pipes 2 are first 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 recovered heat is used to heat the chlorine dioxide gas to increase the diffusion rate of chlorine dioxide. When the exhaust gas moves to the mold frame 34, the purification unit 43 completes the preliminary filtration of the exhaust gas.

[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 that can effectively kill bacteria, viruses, fungi, etc. By atomizing it and bringing it into contact with waste, it can effectively eliminate 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 along the circumferential direction through a circular column. The two blades 3222 are close to the inner wall of the trapezoidal shell 32. The lower end face of the gas 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 bracket 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 and lower end surfaces of the mounting bracket 432. A plurality of T-shaped slots 4322 are provided on the two side walls inside the mounting bracket 432 along the up and down directions. An adsorption carbon plate 433 is slidingly arranged between the two T-shaped slots 4322 at the same height through the T-shaped slider, and an avoidance groove 434 is provided on the side of the T-shaped slot 4322 close to the center of the support disc 41. 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 bracket 432.

[0044] Please refer to Figure 8 The limit group 435 includes a connecting rod 4351 fixedly arranged on two T-shaped sliders near one end of the center of the supporting disc 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. 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 slidingly arranged on the outer wall of the connecting rod 4351. A limit ring is also fixedly arranged 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. The interior of the avoidance groove 434 is symmetrically arranged with a telescopic top rod 4353 in a spring sliding manner. The close end of 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 pipe 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 chlorine dioxide molecules, which is conducive 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 ejector rods 4353. By pushing the adjusting plugs 4352 respectively, the two telescopic ejector rods 4353 are pushed and 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 ejector rods 4353 disappear and then 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 ejector 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 ejector rods 4353 drive the adjusting plugs 4352 to slide and make the two adjusting plugs 4352 close to each other. Continuing to pull the adsorption carbon plate 433, the two adjusting plugs 4352 with the same height will continuously push the corresponding telescopic ejector 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 [reference figure number], the inner side wall of the vertical part of the U-shaped frame 34 is an arc surface. Arc-shaped chutes 341 are provided on the sides close to each other of the upper and lower horizontal sections of the U-shaped frame 34. A strip-shaped chute 342 is provided on the side wall of the vertical section of the U-shaped frame 34 close to the arc-shaped chute 341 along the up-down direction. A pressing part 343 is slidably arranged on the strip-shaped chute 342. Two strip-shaped through grooves distributed along the up-down direction are further provided on the side wall of the vertical section of the U-shaped frame 34 close to the arc-shaped chute 341 and below the strip-shaped chute 342. 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 ​

[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 slidably penetrates 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 arranged 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 conical groove 34331 opened on the end face. A conical plug 3434 that abuts against the conical plug 3434 slides inside the conical groove 34331. The other end of the conical 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. Through the incomplete gear 422 meshing with the driven gear one 423, the support disc 41 rotates intermittently. At this time, the two arc-shaped sliders 4321 on the mounting frame 432 respectively slide into the 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 under the drive of the connecting plate. At this time, the conical 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 conical 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 conical 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. By gradually pressing down the rectangular pressing plate 3432, the waste gas inside the C-shaped frame 34 is pressed into the adsorption carbon plate 433. 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 driven gear one 423. By the pawl 425 abutting against the ratchet 424, it can prevent the support disc 41 from rotating back when rotating 120 degrees, and then ensure the stability of the rotation work.

[0054] Please refer to Figure 10The driving part 57 includes a driving gear 571 rotatably arranged inside the rectangular block. A driving shaft that rotates through the rectangular block and the rectangular shell 5 is fixedly arranged on the front side wall of the driving gear 571. 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 upper and lower staggered manner and are respectively engaged with the driving gear 571 for transmission.

[0055] Please refer to Figure 9 and Figure 10 The stirring portion 56 includes a mounting rod 561 fixedly arranged on the rear side wall of the driving gear 2 571 and the two driven gear 2 572. The outer wall of the mounting rod 561 is fixedly provided with a plurality of mounting rings 562 distributed along the front-to-back direction. 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. The outer wall of the mounting ring 562 is fixedly provided with a plurality of stirring blades 1 563 with the tip facing forward in a circular array. A stirring blade 2 564 with the tip facing backward is also fixedly provided 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 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 stirred and moved 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 inside 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 chlorine dioxide and exhaust gas mixture. 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.
