Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, in particular to waste gas treatment equipment, a method for treating waste gas from plastic processing, and a method for preparing an umbrella. Background Art

[0002] The processing of umbrellas involves the processing of umbrella head and tail beads, plastic waterproof coatings on ordinary umbrella surfaces, or plastic umbrella surfaces. Therefore, waste gas is easily generated during the processing of plastic-containing parts. The main components of the waste gas vary depending on the material of the plastic. The main components include volatile organic compounds (VOCs), dust, acidic gases, and harmful gases produced by the thermal decomposition of plastics. When treating such waste gas, a composite process is generally adopted. Among them, the spray tower is often used as an important equipment for waste gas treatment. Its main purpose is to neutralize the pH value in the gas and can simultaneously remove particulate matter and some water-soluble VOCs. In actual application, the spray tower still has certain problems. For example, the environment inside the spray tower is often characterized by high temperature and high humidity. Therefore, bacteria are easily bred on the packing inside the spray tower and the inner wall of the tower, resulting in the formation of dirt formed by algae or bacterial metabolites, which reduces the effectiveness of the packing and produces odor. If treated with a fungicide, it is easy to affect the pH adjustment and reduce the subsequent waste gas treatment effect of the spray tower. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a waste gas treatment equipment, a plastic processing waste gas treatment method and an umbrella preparation method.

[0020] Example 1: Please refer to Figure 1-Figure 2, an exhaust gas treatment equipment, including a spray tower 1, a demister 2 and a spray pipe 3 installed inside the spray tower 1, and a water storage area 4 arranged at the bottom of the spray tower 1, the spray tower 1 is further provided with a storage cylinder 5 for accommodating fillers, the storage cylinder 5 is located between the spray pipe 3 and the water storage area 4, the side wall of the spray tower 1 is installed with an adjustment component 6 for driving the storage cylinder 5 to move vertically, an annular airbag 7 is fixedly installed on the edge of the storage cylinder 5, an agitator 8 is movably installed inside the storage cylinder 5, and a driving component 9 is further installed on the storage cylinder 5, the driving component 9 is connected to the agitator 8 and the annular airbag 7, the driving component 9 is used to drive the agitator 8 to rotate, and the driving component 9 is also used to inject gas into the annular airbag 7; When dirt appears on the surface of the filler and the inner wall of the spray tower 1, the adjusting component 6 and the driving component 9 operate. When the adjusting component 6 operates, the storage cylinder 5 is driven to move up close to the spray pipe 3. When the driving component 9 operates, the agitator 8 is driven to rotate, forcing the fillers inside the storage cylinder 5 to rub against each other and clean the dirt. At the same time, the driving component 9 also injects air into the annular airbag 7, forcing the annular airbag 7 to expand and fit the inner wall of the spray tower 1. Then the adjusting component 6 operates again, forcing the storage cylinder 5 and the annular airbag 7 to move down, thereby scraping off the dirt on the inner wall of the spray tower 1. Finally, the adjusting component 6 forces the storage cylinder 5 to move back and forth vertically in the water storage area 4, so that the dirt in the filler settles in the water storage area 4.

[0021] Among them, in the initial state, the annular airbag 7 is in a contracted state. At this time, there is a gap between the outer wall of the annular airbag 7 and the inner wall of the spray tower 1. When in use, the filler is placed inside the storage tube 5. When the spray tower 1 is in operation, the exhaust gas passes through the filler from the bottom of the storage tube 5 upward, and the spray pipe 3 sprays water mist onto the storage tube 5. When algae or dirt appears on the inner wall of the spray tower 1 and the filler, the driving component 9 and the adjusting component 6 are started first. After the adjusting component 6 is operated, the storage tube 5 is driven to move up close to the spray pipe 3. When the driving component 9 is in operation, the agitator 8 is driven to rotate. When the agitator 8 rotates, the filler is stirred. The vibration of the filler and the mutual friction between the fillers loosen the dirt adhering to the filler. At the same time, when the driving component 9 is running, air is also injected into the annular airbag 7. After the annular airbag 7 expands, the outer wall of the annular airbag 7 is close to the inner wall of the spray tower 1. Then the adjusting component 6 is started again. The adjusting component 6 forces the storage cylinder 5 to move downward, thereby driving the annular airbag 7 to move downward. The annular airbag 7 scrapes the dirt on the inner wall of the spray tower 1, causing the dirt to fall into the water storage area 4. Finally, the storage cylinder 5 moves down into the water storage area 4. Then the adjusting component 6 drives the storage cylinder 5 to reciprocate vertically, so that the storage cylinder 5 is reciprocally immersed in the liquid in the water storage area 4. The dirt previously loosened on the filler settles with the liquid and falls into the water storage area 4, finally cleaning the filler and the dirt on the inner wall of the spray tower 1. By arranging a storage cylinder 5, an annular airbag 7, an agitator 8, an adjustment component 6 and a drive component 9 inside the spray tower 1, for the dirt on the filler, it is first stirred by the agitator 8 and then the storage cylinder 5 is placed in the water storage area 4 for rinsing. For the dirt on the inner wall of the spray tower 1, the annular airbag 7 is first expanded and then pressed against the inner wall of the spray tower 1, and then the storage cylinder 5 and the annular airbag 7 are driven to move and then the dirt is scraped off. Therefore, the dirt or algae on the filler and the inner wall of the spray tower 1 can be cleaned at the same time, which facilitates maintenance and avoids the adverse effects of dirt on waste gas treatment, which is beneficial to the continuous waste gas treatment work of the spray tower 1.

[0022] Example 2: See Figure 3 , different from the above embodiment, the storage tube 5 is configured as a cylindrical shell with an opening at the top, an assembly frame 51 is fixedly connected to the top of the storage tube 5, a storage cavity 52 is provided inside the storage tube 5, and the bottom wall of the storage tube 5 is provided with evenly distributed grille holes 53, the grille holes 53 are used for ventilation and drainage, and an annular groove 54 is fixed to the bottom edge of the storage tube 5, and the annular airbag 7 is fixed in the annular groove 54; The diameter of the storage tube 5 is smaller than the inner diameter of the spray tower 1. The annular groove 54 includes an inner tube, an upper ring body arranged at the top edge of the inner tube, and a lower ring body arranged at the bottom edge of the inner ring. The annular airbag 7 is exposed on the side close to the inner wall of the spray tower 1, and the thickness of the annular airbag 7 on the side close to the inner wall of the spray tower 1 is greater than that at other positions, so that this part has a better wear resistance and life. When in use, the fillers are placed inside the storage tube 5, the exhaust gas passes through the grille holes 53 from bottom to top, and the liquid inside the storage tube 5 passes through the grille holes 53 and drips into the water storage area 4 below.

[0023] Example 3, see Figure 3 and Figure 4 , different from the above embodiment, the agitator 8 includes a vertical tube 81, the top of the vertical tube 81 is rotatably connected to the assembly frame 51, the bottom end of the vertical tube 81 is rotatably connected to the bottom wall of the storage tube 5, the side wall of the vertical tube 81 is fixed with a plurality of stirring rods 82 distributed in a ring array, the stirring rods 82 are located in the storage tube 5, the top of the vertical tube 81 is fixed with a driven bevel gear 83, the bottom end of the vertical tube 81 extends to the bottom of the storage tube 5 and is fixed with a driving gear 84, the driving assembly 9 includes a main motor 901 fixed to the top of the assembly frame 51, the output shaft of the main motor 901 is fixed with a driving bevel gear 902, and the driving bevel gear 902 is meshed with the driven bevel gear 83.

[0024] When in use, the main motor 901 is started. When the main motor 901 is running, it drives the active bevel gear 902 to rotate. When the active bevel gear 902 rotates, it drives the driven bevel gear 83 to rotate, and then drives the vertical tube 81 to rotate. When the vertical tube 81 rotates, it drives the multiple stirring rods 82 to rotate. When the stirring rods 82 rotate, the filler is stirred, causing the filler to vibrate and rub against each other, loosening the dirt on the surface, and the driving gear 84 at the bottom end of the vertical tube 81 also rotates accordingly; By arranging the agitator 8 and the main motor 901 on the storage cylinder 5, the agitator 8 can be driven to rotate when the main motor 901 is started, which is conducive to stirring the filler in the storage cylinder 5, forcing the filler to vibrate and rub, thereby loosening the dirt for subsequent cleaning.

[0025] Example 4, see Figure 6 and Figure 7 , different from the above embodiment, the adjusting component 6 is arranged in multiple groups and distributed in a circular array on the side wall of the spray tower 1, the adjusting component 6 includes an auxiliary motor 61 fixed on the side wall of the spray tower 1, the output shaft of the auxiliary motor 61 extends to the interior of the spray tower 1 and is fixed with a reel 62, a steel wire rope 63 is fixed and wound on the reel 62, the bottom end of the steel wire rope 63 is fixedly connected to the top edge of the storage tube 5, the adjusting component 6 also includes a spring 64, the top end of the spring 64 is fixed to the bottom of the storage tube 5, and the bottom end of the spring 64 is fixedly connected to the inner bottom wall of the spray tower 1.

[0026] Among them, the number of springs 64 is set to be multiple, and multiple springs 64 are distributed in a circular array. In the initial state, the springs 64 are in a stretched state. When in use, multiple auxiliary motors 61 are started. When the auxiliary motor 61 is running, it drives the reel 62 to rotate. When the reel 62 rotates, it pulls the wire rope 63, thereby pulling the storage drum 5 up, and the storage drum 5 further pulls the spring 64 when it moves up. When the auxiliary motor 61 drives the reel 62 to rotate in the opposite direction, the storage drum 5 is forced to move downward under the gravity of the storage drum 5 and the tension of the spring 64. If the annular airbag 7 on the edge of the storage drum 5 is in contact with the inner wall of the spray pipe 3 at this time, the annular airbag 7 can be used to scrape and clean the inner wall of the spray pipe 3 during the downward movement of the storage drum 5. In addition, when the storage drum 5 is immersed in the water storage area 4, the adjustment component 6 controls the vertical reciprocating motion of the storage drum 5, which can rinse the storage drum 5, so that the dirt on the filler in the storage drum 5 is settled in the liquid in the water storage area 4, and then separated from the filler.

[0027] Example 5, see Figure 3-Figure 5, different from the above embodiment, the driving assembly 9 further includes a vertical shaft 903 and a piston cylinder 904, the vertical shaft 903 is rotatably connected to the bottom wall of the storage cylinder 5, a transmission gear 905 is fixed on the vertical shaft 903, the transmission gear 905 is meshed with the driving gear 84, a push rod 906 is provided at the bottom of the transmission gear 905, one end of the push rod 906 is rotatably connected to the bottom of the transmission gear 905 through a rotating shaft, and the other end of the push rod 906 extends to the piston cylinder 904 A piston 907 is hinged inside, and an intake pipe 908 and an exhaust pipe 909 are fixed on the piston cylinder 904. A one-way valve is provided at the connection between the intake pipe 908 and the piston cylinder 904, and at the connection between the exhaust pipe 909 and the piston cylinder 904. The top end of the intake pipe 908 passes through the interior of the vertical pipe 81 and extends to the top of the vertical pipe 81. The exhaust pipe 909 is fixed to the bottom wall of the storage tube 5. One end of the exhaust pipe 909 passes through the annular groove 54 and is fixed to the annular airbag 7.

[0028] The distance between the connection point between the push rod 906 and the transmission gear 905 and the bottom center of the transmission gear 905 is greater than 0. The one-way valve on the intake pipe 908 only allows gas to enter the piston cylinder 904. The one-way valve on the exhaust pipe 909 only allows gas to enter the exhaust pipe 909 from the piston cylinder 904. A support rod is welded between the exhaust pipe 909 and the bottom wall of the storage tube 5 to achieve fixation. When the main motor 901 is running, it can drive the vertical pipe 81, the agitator 8 on the vertical pipe 81 and the driving gear 84 at the bottom of the vertical pipe 81 to rotate. When the driving gear 84 rotates, it drives the driving gear 84 to rotate. When the driving gear 84 rotates, it drives the transmission gear 905 and the vertical shaft 903 to rotate. When the transmission gear 905 rotates, it drives one end of the push rod 906 to make a reciprocating circular motion, thereby causing the other end of the push rod 906 to push the piston 907 to move back and forth. When the piston 907 moves back and forth, it first sucks gas from the air inlet pipe 908 into the piston cylinder 904, and then discharges it into the annular airbag 7 through the exhaust pipe 909, thereby inflating the annular airbag 7. The inflated annular airbag 7 expands and clings to the inner wall of the spray tower 1; By setting up the driving component 9 and utilizing the driving gear 84, piston cylinder 904 and other structures, the annular airbag 7 can be inflated while stirring the filler, so that the annular airbag 7 is close to the inner wall of the spray tower 1, which is conducive to cooperating with the adjusting component 6 to clean the dirt on the inner wall of the spray tower 1.

[0029] Example 6, see Figure 3 , different from the above embodiment, a branch pipe 10 is fixed on the exhaust pipe 909, the top of the branch pipe 10 passes through the storage tube 5 and extends to the top of the assembly frame 51, an air bag 11 is fixed on the top of the branch pipe 10, a filter 12 is fixed on the top of the intake pipe 908, an output pipe 13 is fixed on the air bag 11, one end of the output pipe 13 is connected to the filter 12, and a pulse valve 14 is provided on the output pipe 13.

[0030] Among them, the filter 12 is a prior art, which is used to filter the gas entering the intake pipe 908. The exhaust pipe 909 is provided with a first valve, and the branch pipe 10 is provided with a second valve. When the annular airbag 7 is inflated, if the internal pressure of the annular airbag 7 reaches a specified value, the first valve is closed and the second valve is opened. At this time, the gas in the exhaust pipe 909 no longer enters the annular airbag 7, but enters the air bag 11 through the branch pipe 10. The air pressure in the air bag 11 continues to increase. Thereafter, the pulse valve 14 is activated at regular intervals. The pulse valve 14 allows the high-pressure gas in the air bag 11 to be discharged in the form of a pulsed airflow, which passes through the output pipe 13 and enters the filter 12 to clean the dust attached to the outside of the filter 12. Among them, by setting up the branch pipe 10 and the air bag 11, the air bag 11 can store excess gas, which is beneficial to avoid the annular airbag 7 being damaged after the driving component 9 over-inflates the annular airbag 7. At the same time, the high-pressure airflow stored in the air bag 11 can also be injected into the filter 12 in the form of pulse airflow, thereby cleaning the filter 12 and preventing the filter 12 at the end of the intake pipe 908 from being blocked.
