Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of waste gas treatment, and specifically relates to an exhaust gas purification device for a real stone paint production line. Background Art
[0002] Real stone paint is a thick paint with a decorative effect similar to natural stone. It is made of natural stone powder of various colors, different polymer emulsion and other additives. This kind of paint is widely used for the decoration of building facades, and can provide the appearance effect similar to natural stones such as granite and marble. Therefore, it is also called liquid stone. During its production, certain waste gas will be generated, and these waste gases mainly come from the steps such as the mixing and dispersion of raw materials and the volatilization of solvents. The main component is volatile organic compound (VOCs) waste gas.
[0003] In order to reduce the pollution of air by volatile organic compound (VOCs) waste gas, waste gas purification equipment is installed on the real stone paint production line to purify the VOCs waste gas. During the use of the purification equipment, it is found that the catalyst for purifying waste gas basically remains stationary. This will cause the side of the catalyst facing the waste gas to efficiently purify the waste gas, while the side facing away from the waste gas cannot efficiently complete the waste gas purification function. This will cause the catalyst not to be fully utilized, thus affecting the purification effect of VOCs waste gas. Summary of the Invention

[0011] Furthermore, a lower short pipe is fixedly connected to the inner bottom of the purification pipe. Multiple circumferentially distributed V-shaped pipes are fixedly connected to the lower end of the lower short pipe. The turning points of the V-shaped pipes face towards the inside of the annular pool. A recovery pipe extending into the annular pool is fixedly connected to the outer wall of the lower pipe. A circulation part connected to the lower short pipe and the V-shaped pipes is provided in the upper pipe.
[0012] Furthermore, the circulation part includes an upper short pipe fixedly connected in the upper pipe. Multiple heat dissipation pipes communicated with the upper short pipe are fixedly connected to the outer wall of the upper end of the upper short pipe. The multiple heat dissipation pipes are respectively fixedly connected to the ends of the multiple V-shaped pipes through connecting pipes. The lower end of the upper short pipe is fixedly connected to the top end of the lower short pipe through a return pipe. A circulation component is arranged in the middle of the return pipe.
[0013] Furthermore, the circulation component includes a rotating pipe rotatably connected in the middle of the return pipe. An impeller is fixedly installed in the rotating pipe. A fifth gear is fixedly installed on the outer wall of the rotating pipe. A second annular gear meshed with the fifth gear is fixedly connected to the inner wall of the annular platform.
[0014] Furthermore, a dust filtering pipe is fixedly connected to the frame body. A cylindrical filter screen is rotatably installed at the upper end of the dust filtering pipe.

[0016] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art:
[0017] 1. In the present invention, the first motor drives the heating element and the horizontal pipe to rotate synchronously. Thus, the heating element and the horizontal pipe can stir the waste gas in the purification pipe. On the one hand, it makes the waste gas heated more fully. On the other hand, it can make the waste gas contact the surface of the purification particles more fully, so as to improve the effect of the purification particles in purifying the waste gas.
[0018] 2. In the present invention, the horizontal pipe drives the fourth gear to roll along the first annular gear. Thus, the fourth gear will drive the horizontal pipe to rotate self - sufficiently. The horizontal pipe will continuously turn the purification particles inside. In this way, the waste gas can contact the surface of the purification particles more fully, further improving the effect of purifying the waste gas. At the same time, it can also prevent some floating dust in the waste gas from always adhering to the surface of the purification particles.
[0019] 3. In the present invention, the continuously rotating horizontal pipe will continuously change the function of the air - permeable grooves on its outer wall. When the air - permeable groove is used as the air inlet, some remaining floating dust in the waste gas may block the air - permeable groove. When the air - permeable groove is used as the air outlet, the discharged air flow will dredge the air - permeable groove. In this way, it can effectively ensure the ventilation efficiency of the air - permeable groove and indirectly ensure the purification efficiency of the waste gas.
[0020] 4. In the present invention, through the setting of the rollers and the arch plates, the continuously rotating purification pipe will also move up and down reciprocally. In this way, the movement trajectories of the heating element and the purification particles can be more diverse. Furthermore, it can further improve the efficiency of heating the waste gas and the effect of purifying the waste gas. Moreover, it can also make the floating dust in the waste gas not easily adhere to the horizontal pipe, the purification particles and the heating element, ensuring the effect of purifying the waste gas.
[0021] The following further describes in detail the specific implementation manners of the present invention with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0033] Embodiment 1: Refer to Figures 1-8, A processing device for a four-way elastic washable fabric that is convenient for ironing, including a frame 1 for supporting the entire device, and further including: an upper pipe 2 and a lower pipe 3 symmetrically distributed up and down, both fixedly connected to the frame 1. Among them, a purification pipe 4 that is interconnected is sleeved between the upper pipe 2 and the lower pipe 3. A plurality of hollow horizontal pipes 5 are rotatably installed in the purification pipe 4. Purification particles 7 are arranged in the horizontal pipes 5. The purification particles 7 are catalysts, and the catalysts are used to oxidize and convert waste gas into water and carbon dioxide. The outer wall of the horizontal pipe 5 is provided with air permeable grooves 6. A driving part for driving the purification pipe 4 to rotate is provided on the frame 1. The driving part includes a first motor 10 fixedly installed on the frame 1. The output end of the first motor 10 is fixedly installed with a first gear 11. The outer wall of the purification pipe 4 is fixedly installed with a second gear 12 meshed with the first gear 11; a heating element 13 fixedly installed in the purification pipe 4, and the heating element 13 is close to the air inlet end of the purification pipe 4. The heating element 13 can be an electric heating wire for heating.
[0034] Specifically, during use, the waste gas generated during the production of real stone paint is conveyed into the upper pipe 2. Immediately afterwards, the waste gas will successively enter the purification pipe 4 and the lower pipe 3, and finally be discharged from the lower port of the lower pipe 3. When the waste gas passes through the purification pipe 4, the heating element 13 will first heat the waste gas, and the temperature of the waste gas is raised to between 200°C and 400°C. The heated waste gas will pass through the inside of the horizontal pipe 5 through the air permeable grooves 6, and the purification particles 7 inside the horizontal pipe 5 will undergo an oxidation reaction to be converted into carbon dioxide and water, thus completing the purification work of the waste gas. During this period, the first motor 10 will drive the first gear 11 to rotate, the first gear 11 will drive the second gear 12 to rotate, the second gear 12 will drive the purification pipe 4 to rotate, and the purification pipe 4 will drive the heating element 13 and the horizontal pipe 5 to rotate synchronously. Therefore, the heating element 13 and the horizontal pipe 5 can stir the waste gas in the purification pipe 4. On the one hand, the waste gas can be heated more fully, and on the other hand, the waste gas can be more fully in contact with the surface of the purification particles 7 to improve the effect of the purification particles 7 in purifying the waste gas.
[0035] In practice, in order to prevent the purification particles 7 in the same horizontal pipe 5 from accumulating with each other, the cavity in the horizontal pipe 5 can be provided with multiple groups and separated from each other. Only one purification particle 7 can be placed in each cavity, and the shape is preferably long strip or spherical.
[0036] In order to enable the waste gas to better contact the surface of the purification particles 7, a spherical convex block 8 is fixedly connected in the horizontal pipe 5, which can reduce the contact area between the purification particles 7 and the inner wall of the horizontal pipe 5. The partition plate 9 can block the gap between adjacent horizontal pipes 5, which can reduce the escape of waste gas from the gap between adjacent horizontal pipes 5.
[0037] Example 2: Refer to Figures 1-7 , A processing device for a four-way elastic washable fabric that is convenient for ironing, which is basically the same as Example 1. Further:
[0038] Third gears 14 are fixedly installed at the axial ends of the multiple horizontal pipes 5. The two adjacent third gears 14 are meshed and connected. A fourth gear 15 is fixedly installed at the axial end of one of the horizontal pipes 5. An annular plate 16 is connected to the frame 1, and a first annular gear 17 meshed with the fourth gear 15 is fixedly installed on the annular plate 16.
[0039] Specifically, during the rotation of the purification pipe 4, the purification pipe 4 drives the horizontal pipe 5 to rotate, and the horizontal pipe 5 drives the fourth gear 15 to roll along the first annular gear 17. Then the fourth gear 15 drives the horizontal pipe 5 to rotate self - sufficiently, and the horizontal pipe 5 makes the purification particles 7 inside continuously turn over. In this way, the exhaust gas can be more fully in contact with the surface of the purification particles 7, further improving the effect of purifying the exhaust gas. At the same time, it can also prevent some floating dust in the exhaust gas from always adhering to the surface of the purification particles 7. The continuously rotating horizontal pipe 5 makes the air - permeable grooves 6 on its outer wall constantly change functions. That is, when the air - permeable grooves 6 face the exhaust gas, the air - permeable grooves 6 serve as the air inlet of the horizontal pipe 5. On the contrary, when the air - permeable grooves 6 deviate from the exhaust gas, the air - permeable grooves 6 serve as the exhaust port of the horizontal pipe 5. When the air - permeable grooves 6 serve as the air inlet, some remaining floating dust in the exhaust gas may block the air - permeable grooves 6. When the air - permeable grooves 6 serve as the exhaust port, the discharged air flow will dredge the air - permeable grooves 6. In this way, the ventilation efficiency of the air - permeable grooves 6 can be effectively guaranteed, indirectly guaranteeing the purification efficiency of the exhaust gas.
[0040] An annular pool 18 is fixedly connected to the inner wall of the lower pipe 3. The lower end of the purification pipe 4 is located in the annular pool 18. The annular pool 18 is used to limit the further downward sliding of the purification pipe 4. A plurality of circumferentially distributed arch plates 19 are fixedly connected in the annular pool 18. A roller 20 located in the annular pool 18 is rotatably installed at the lower end of the purification pipe 4.
[0041] Specifically, when the purification pipe 4 rotates, the purification pipe 4 drives the roller 20 to roll in the annular pool 18. When the roller 20 presses on the arch plate 19, the arch plate 19 makes the roller 20 lift upward and makes the purification pipe 4 lift upward. When the roller 20 passes over the arch plate 19, the purification pipe 4 and the roller 20 move downward and reset. Therefore, the continuously rotating purification pipe 4 will also move up and down reciprocally. In this way, the movement trajectories of the heating element 13 and the purification particles 7 can be more diverse, further improving the efficiency of heating the exhaust gas and the effect of purifying the exhaust gas. Moreover, it can also prevent the floating dust in the exhaust gas from easily adhering to the horizontal pipe 5, the purification particles 7 and the heating element 13, guaranteeing the effect of purifying the exhaust gas.
[0042] An annular platform 29 is fixedly connected to the frame 1. A vertical rod 30 is fixedly connected to the lower end of the annular plate 16. The vertical rod 30 is longitudinally slidably installed on the annular platform 29. A spring 31 is installed between the annular plate 16 and the annular platform 29.
[0043] Specifically, when the purification pipe 4 drives the fourth gear 15 to move up and down, the spring 31 can keep the first annular gear 17 on the annular plate 16 always meshed with the fourth gear 15.
[0044] Embodiment 3: Refer to Figures 3-6 , a processing device for a four-way stretch washable and wearable fabric that is convenient for ironing, which is basically the same as Embodiment 2. Further:
[0045] The inner bottom of the above-mentioned purification pipe 4 is fixedly connected with a lower short pipe 22. The lower end of the lower short pipe 22 is fixedly connected with a plurality of circumferentially distributed V-shaped pipes 21. The turning part of the V-shaped pipe 21 faces the inside of the annular pool 18. The outer wall of the lower pipe 3 is fixedly connected with a recovery pipe 37 extending into the annular pool 18. A circulation part connected to the lower short pipe 22 and the V-shaped pipe 21 is arranged in the upper pipe 2. The circulation part includes an upper short pipe 23 fixedly connected in the upper pipe 2. The outer wall of the upper end of the upper short pipe 23 is fixedly connected with a plurality of heat dissipation pipes 25 communicated with it. The plurality of heat dissipation pipes 25 are respectively fixedly connected with the ends of the plurality of V-shaped pipes 21 through connecting pipes 24. The lower end of the upper short pipe 23 is fixedly connected with the top end of the lower short pipe 22 through a return pipe 26. A circulation component is arranged in the middle of the return pipe 26. Coolant is provided in the return pipe 26, the V-shaped pipe 21, the lower short pipe 22, the upper short pipe 23, the connecting pipe 24 and the heat dissipation pipe 25.
[0046] Specifically, during the rotation of the purification pipe 4, the purification pipe 4 will make the coolant in the return pipe 26, the V-shaped pipe 21, the lower short pipe 22, the upper short pipe 23, the connecting pipe 24 and the heat dissipation pipe 25 circulate through the circulation component. When the coolant enters the V-shaped pipe 21, the V-shaped pipe 21 will condense the purified gas. The water generated by condensation will flow along the outer wall of the V-shaped pipe 21 towards the turning part below it, and finally will flow back into the annular pool 18, thus completing the recovery work of part of the waste gas after purification. During the recovery period, the moving up and down and rotating purification pipe 4 will make the condensation and recovery efficiency of the waste gas higher. After the coolant passes through the V-shaped pipe 21, it will be heated. After the heated coolant enters the heat dissipation pipe 25, the heat dissipation pipe 25 will heat the unheated waste gas, preheating the waste gas and reducing waste of resources. Moreover, the rotating and lifting purification pipe 4 will make the heat dissipation pipe 25 rotate and lift synchronously, thereby improving the preheating effect on the waste gas.
[0047] The above-mentioned circulation component includes a rotating pipe 27 rotatably connected to the middle of the return pipe 26. An impeller is fixedly installed in the rotating pipe 27 for pushing the coolant to flow. The outer wall of the rotating pipe 27 is fixedly installed with a fifth gear 42. The inner wall of the annular platform 29 is fixedly connected with a second annular gear 28 meshed with the fifth gear 42.
[0048] Specifically, during the rotation of the purification pipe 4, the purification pipe 4 drives the fifth gear 42 to roll along the second annular gear 28. The fifth gear 42 drives the rotating pipe 27 to rotate, the rotating pipe 27 drives the internal impeller to rotate, and the impeller pushes the coolant in the return pipe 26 to flow.
[0049] Example 4: Refer to Figure 1 , Figure 2 , Figure 4 and Figure 8 , a processing device for a four-way stretch washable fabric that is convenient for ironing, which is basically the same as Example 3. Furthermore:
[0050] A dust filter pipe 32 is fixedly connected to the above-mentioned frame body 1. The upper end of the dust filter pipe 32 is rotatably installed with a cylindrical filter screen 33 for filtering the dust remaining in the waste gas. The lower half of the cylindrical filter screen 33 is located inside the dust filter pipe 32. The upper port of the cylindrical filter screen 33 is fixedly connected to the top of the upper pipe 2 through a delivery pipe 34. Among them, an annular cover 35 that shields the cylindrical filter screen 33 is fixedly connected to the upper end of the dust filter pipe 32. A second motor 39 is fixedly installed on the outer wall of the annular cover 35. Transmission gears 40 are fixedly installed on the output shaft of the second motor 39 and the outer wall of the cylindrical filter screen 33, and the two transmission gears 40 are meshed and connected. A flushing part facing the cylindrical filter screen 33 is provided at the upper end of the annular cover 35; the flushing part includes a water storage tank 36 fixedly installed on the annular cover 35. The lower end of the water storage tank 36 is fixedly connected to a spray pipe 38 communicated with it. Nozzles facing the outer wall of the top of the cylindrical filter screen 33 are fixedly installed on the spray pipe 38 for spraying water to flush the cylindrical filter screen 33. An electromagnetic valve is fixedly installed in the spray pipe 38. The end of the recovery pipe 37 extends into the water storage tank 36. A sewage pool 41 is fixedly connected inside the annular cover 35. The sewage pool 41 and the spray pipe 38 are located on both sides of the cylindrical filter screen 33 respectively.
[0051] Specifically, the water recovered in the annular pool 18 enters the water storage tank 36 through the recovery pipe 37. After the cylindrical filter screen 33 is used for a period of time, the second motor 39 is started and the electromagnetic valve in the spray pipe 38 is opened. The second motor 39 drives the cylindrical filter screen 33 to rotate through two meshing transmission gears 40, and the spray pipe 38 sprays the water recovered in the water storage tank 36 onto the surface of the cylindrical filter screen 33 through the nozzles. Thus, backwashing of the cylindrical filter screen 33 can be realized, and the wastewater generated by the flushing is discharged through the sewage pool 41. Thus, the recovered water can be effectively utilized.
[0052] In the use of the present invention, the waste gas generated during the production of real stone paint is conveyed into the dust filter pipe 32. After the waste gas is filtered by the cylindrical filter screen 33, it is conveyed into the upper pipe 2 through the conveying pipe 34. Then, it will successively enter the purification pipe 4 and the lower pipe 3, and finally be discharged from the lower port of the lower pipe 3. When the waste gas passes through the purification pipe 4, the heating element 13 will first heat the waste gas, and the temperature of the waste gas is raised to between 200°C and 400°C. The heated waste gas will pass through the ventilation slots 6 and pass through the inside of the horizontal pipe 5. The purification particles 7 inside the horizontal pipe 5 will undergo an oxidation reaction to be converted into carbon dioxide and water, thus completing the purification of the waste gas. During this period, the first motor 10 will drive the first gear 11 to rotate, the first gear 11 will drive the second gear 12 to rotate, the second gear 12 will drive the purification pipe 4 to rotate, and the purification pipe 4 will drive the heating element 13 and the horizontal pipe 5 to rotate synchronously. Therefore, the heating element 13 and the horizontal pipe 5 can stir the waste gas in the purification pipe 4. On the one hand, it can make the waste gas be heated more fully, and on the other hand, it can make the waste gas contact the surface of the purification particles 7 more fully, so as to improve the effect of the purification particles 7 in purifying the waste gas.
[0053] During the rotation of the purification pipe 4, the purification pipe 4 will drive the horizontal pipe 5 to rotate, and the horizontal pipe 5 will drive the fourth gear 15 to roll along the first annular gear 17. Then, the fourth gear 15 will drive the horizontal pipe 5 to rotate itself, and the horizontal pipe 5 will continuously turn the purification particles 7 inside. This can make the waste gas contact the surface of the purification particles 7 more fully, further improving the effect of purifying the waste gas. At the same time, it can also prevent some floating dust in the waste gas from always adhering to the surface of the purification particles 7. The continuously rotating horizontal pipe 5 will continuously change the function of the ventilation slots 6 on its outer wall. That is, when the ventilation slots 6 face the waste gas, the ventilation slots 6 will serve as the air inlet of the horizontal pipe 5. On the contrary, when the ventilation slots 6 face away from the waste gas, the ventilation slots 6 will serve as the exhaust port of the horizontal pipe 5. When the ventilation slots 6 serve as the air inlet, some remaining floating dust in the waste gas may block the ventilation slots 6. When the ventilation slots 6 serve as the exhaust port, the discharged air flow will dredge the ventilation slots 6. This can effectively ensure the ventilation efficiency of the ventilation slots 6 and indirectly ensure the purification efficiency of the waste gas.
