Description

Technical Field

[0001] The present invention relates to the technical field of waste gas separation and treatment, and specifically to an apparatus and method for separating and treating waste gas in the production of rubber additives. Background Art

[0002] Rubber additives are indispensable raw materials in the rubber industry and are widely used in the production of rubber products such as tires, hoses, tapes, and rubber shoes. However, during the production process of rubber additives, high-temperature and toxic waste gas is generated. Before these waste gases are allowed to be discharged into the atmosphere, they must be treated to remove harmful substances therein to ensure that irreversible damage is not caused to the surrounding environment and the health of residents.

[0003] In the existing apparatus and method for separating and treating waste gas in the production of rubber additives, before treating the high-temperature and toxic waste gas, multiple copper tubes filled with cold water inside are usually used to contact the waste gas to recover the heat in the high-temperature waste gas. However, the particulate matter in the waste gas is likely to condense and deposit on the outer wall of the copper tubes after being cooled, resulting in a reduction in the effective contact area between the copper tubes and the waste gas, thereby weakening the heat exchange efficiency and causing the heat in the high-temperature waste gas not to be fully recovered and utilized. Therefore, it is necessary to provide an apparatus and method for separating and treating waste gas in the production of rubber additives to solve the above technical problems.

[0014] The present invention also provides a method for separating and treating waste gas in the production of rubber auxiliaries. Using the waste gas separation and treatment equipment for the production of rubber auxiliaries, the specific method includes the following steps: Step 1: Pass the high-temperature waste gas generated during the production of rubber auxiliaries into the heat preservation cylinder through the air inlet pipe. At the same time, use an external pump body to pass external cool water into each first heat exchange pipe assembly and each second heat exchange pipe assembly through the water injection pipe and the left disc cover. During the process of the water flow entering the left disc cover, it impacts the impeller to make it rotate, and the driving gear rotates accordingly. Then the cool water flows to the right through the interiors of the first heat exchange pipe assembly and the second heat exchange pipe assembly. At the same time, the high-temperature waste gas entering the heat preservation cylinder comes into contact with the outer walls of the first heat exchange pipe assembly and the second heat exchange pipe assembly. The high-temperature waste gas transfers heat to the water in the first heat exchange pipe assembly and the second heat exchange pipe assembly through the first heat exchange pipe assembly and the second heat exchange pipe assembly, causing the water temperature to rise and the waste gas temperature to drop, for heat exchange. Step 2: After the particulate matter in the waste gas is cooled, under the action of gravity, it deposits on the outer walls of the first heat exchange pipe assembly and the second heat exchange pipe assembly. Since the driving gear rotates while driving the first heat exchange pipe assembly and the second heat exchange pipe assembly to scrape their own outer walls, the particulate matter deposited on the outer walls of the first heat exchange pipe assembly and the second heat exchange pipe assembly is scraped off in time, and the scraped-off particulate matter falls into the slag collection box. Step 3: Under the action of the upper second heat exchange pipe assembly, the interior of the gas outlet elbow assembly is intermittently opened, so that after the waste gas completes sufficient heat exchange, it enters the treatment barrel through the gas outlet elbow assembly. The waste gas passes through two packing filter layers from bottom to top in the treatment barrel. During this process, due to the operation of the water pump, the external spraying liquid is suctioned into the drain pipe, the branch pipe, and the annular pipe through the water suction pipe, and finally sprayed downward through each nozzle onto the corresponding packing filter layer. When the waste gas passes through the packing filter layer, the harmful substances in the waste gas contact and react with the spraying liquid in the packing filter layer, thereby removing the harmful substances in the waste gas. The purified gas is finally discharged through the exhaust pipe, and the sewage in the treatment barrel is discharged through the sewage discharge pipe. Beneficial effects

[0015] The present invention provides an exhaust gas separation and treatment device and method for rubber auxiliary production. Compared with the prior art, it has the following beneficial effects: 1. For the exhaust gas separation and treatment device and method in rubber auxiliary production, through the mutual cooperation among the heat preservation cylinder, the first heat exchange pipe assembly, the second heat exchange pipe assembly and the air outlet elbow assembly, before the high-temperature exhaust gas enters the treatment barrel, it first enters the heat preservation cylinder, exchanges heat with the cold water in the first heat exchange pipe assembly and the second heat exchange pipe assembly. At the same time, under the action of the upper second heat exchange pipe assembly, the inside of the air outlet elbow assembly is intermittently opened, prolonging the time of the exhaust gas in the heat preservation cylinder, improving the heat exchange efficiency, enabling the exhaust gas to complete sufficient heat exchange and then enter the treatment barrel through the air outlet elbow assembly, realizing the full recovery and reuse of the heat in the high-temperature exhaust gas, and then removing the harmful substances in the exhaust gas.

[0016] 2. For the exhaust gas separation and treatment device and method in rubber auxiliary production, through the mutual cooperation among the driving gear, the impeller, the first toothed ring, the first spiral scraping rod, the second toothed ring and the second spiral scraping rod, when the water flow enters the left disc cover, it will impact the impeller to make it rotate, and the driving gear rotates accordingly, thereby driving the first toothed ring, the first spiral scraping rod, the second toothed ring and the second spiral scraping rod to rotate. During the rotation of the first spiral scraping rod and the second spiral scraping rod, the outer wall of the copper pipe can be automatically and timely scraped, and the particulate matter that falls on the outer wall of the copper pipe due to cooling in the exhaust gas can be scraped off in time, avoiding the influence of the deposition of particulate matter on the outer wall of the copper pipe on the heat exchange efficiency. Through the arrangement of the first flow disturbing blades and the second flow disturbing blades, as the first spiral scraping rod and the second spiral scraping rod rotate, several first flow disturbing blades and several second flow disturbing blades also rotate. During the rotation of the first flow disturbing blades and the second flow disturbing blades, the exhaust gas in the heat preservation cylinder is disturbed, enabling the exhaust gas in the heat preservation cylinder to fully contact the outer wall of the copper pipe, further improving the heat exchange efficiency.

[0017] 3. For the exhaust gas separation and treatment device and method in rubber auxiliary production, through the mutual cooperation among the trapezoidal convex block, the receiving pipe, the support rod, the stop block, the second semi-circular block and the third spring, during the rotation of the upper second spiral scraping rod, the corresponding sleeve ring and the corresponding trapezoidal convex block are driven to rotate. During the rotation of the trapezoidal convex block, it will contact the bottom of the second semi-circular block, and then intermittently push the stop block to move upward, enabling the exhaust gas in the heat preservation cylinder to be discharged upward through the gap between the stop block and the receiving pipe and enter the treatment barrel. Since the inside of the air outlet elbow assembly is intermittently opened, the time of the exhaust gas in the heat preservation cylinder is prolonged, enabling the high-temperature exhaust gas to fully exchange heat with water.

[0018] 4. Exhaust gas separation and treatment equipment and method for rubber auxiliaries production. Through the mutual cooperation among the trapezoidal convex block, the first semi-circular block, the first wedge block, the second wedge block and the push plate, during the rotation of the lower second spiral scraping rod, the corresponding collar and the corresponding trapezoidal convex block are driven to rotate. During the rotation of the trapezoidal convex block, it will contact the top of the first semi-circular block, and then intermittently push the first wedge block downward. During the downward movement of the first wedge block, it can push the second wedge block and the push plate to move leftward, realizing the intermittent pushing of the push plate. Under the action of the intermittent pushing, the push plate pushes the particulate matter falling into the collection bin to the left, making the originally scattered particulate matter gradually accumulate together, facilitating the subsequent rapid cleaning work.

Through the mutual cooperation among the trapezoidal convex block 587, the receiving pipe 592, the support rod 595, the stop block 596, the second semi-circular block 597 and the third spring 598, during the rotation of the upper second spiral scraping rod 584, the corresponding collar 586 and the corresponding trapezoidal convex block 587 are driven to rotate. During the rotation of the trapezoidal convex block 587, it will contact the bottom of the second semi-circular block 597, and then intermittently push the stop block 596 upward, so that the waste gas in the heat preservation cylinder 51 is discharged upward through the gap between the stop block 596 and the receiving pipe 592 and enters the treatment barrel 1. Since the inside of the air outlet elbow assembly 59 is intermittently opened, the time of the waste gas in the heat preservation cylinder 51 is prolonged, enabling the high-temperature waste gas to fully exchange heat with water. Through the mutual cooperation among the trapezoidal convex block 587, the first semi-circular block 520, the first wedge block 521, the second wedge block 524 and the push plate 525, during the rotation of the lower second spiral scraping rod 584, the corresponding collar 586 and the corresponding trapezoidal convex block 587 are driven to rotate. During the rotation of the trapezoidal convex block 587, it will contact the top of the first semi-circular block 520, and then intermittently push the first wedge block 521 downward. During the downward movement of the first wedge block 521, it can push the second wedge block 524 and the push plate 525 to move leftward, realizing the intermittent pushing of the push plate 525. Under the action of the intermittent pushing, the push plate 525 pushes the particulate matter that has fallen into the collection bin 515 to the left, making the originally scattered particulate matter gradually accumulate together, providing convenience for subsequent rapid cleaning work.

[0026] The embodiment of the present invention also provides a waste gas separation and treatment method for rubber auxiliary production, which adopts the waste gas separation and treatment equipment for rubber auxiliary production. The specific method includes the following steps: Step 1: Pass the high-temperature waste gas generated during the production of rubber auxiliaries into the heat preservation cylinder 51 through the air inlet pipe 510. At the same time, use an external pump to pass external cold water into each first copper pipe 571 and each second copper pipe 581 through the water injection pipe 512 and the left disc cover 511. When the water flows into the left disc cover 511, it impacts the impeller 56 to make it rotate, and the driving gear 55 rotates accordingly. Then, the cold water flows to the right through the interiors of the first copper pipe 571 and the second copper pipe 581. At the same time, the high-temperature waste gas entering the heat preservation cylinder 51 comes into contact with the outer walls of the first copper pipe 571 and the second copper pipe 581. The high-temperature waste gas transfers heat to the water in the first copper pipe 571 and the second copper pipe 581 through the first copper pipe 571 and the second copper pipe 581, causing the water temperature to rise and the waste gas temperature to drop, and performing heat exchange. The water with the increased temperature flows out from each copper pipe through the right water inlet 52, and finally flows through the interiors of the right disc cover 513 and the water outlet pipe 514 to a specified external location; Step 2: After the particulate matter in the waste gas cools down, under the action of gravity, it deposits on the outer walls of the first copper pipe 571 and the second copper pipe 581. Since the driving gear 55 rotates while driving the first tooth ring 573, the first spiral scraping rod 574, the second tooth ring 583, and the second spiral scraping rod 584 to rotate, during the rotation of the first spiral scraping rod 574 and the second spiral scraping rod 584, the outer walls of the copper pipes are automatically and timely scraped, and the particulate matter that has fallen onto the outer walls of the copper pipes due to cooling in the waste gas is timely scraped off. The scraped particulate matter falls into the slag collection box 515; Step 3: Under the action of the upper second heat exchange pipe assembly 58, the interior of the air outlet elbow assembly 59 is intermittently opened, so that after the waste gas completes sufficient heat exchange, it enters the treatment barrel 1 through the air outlet elbow assembly 59. The waste gas passes through the two packing filter layers 12 from bottom to top in the treatment barrel 1. During this process, due to the operation of the water pump 7, the external spraying liquid is suctioned into the drain pipe 8, the branch pipe 9, and the annular pipe 10 through the water suction pipe 13. The spraying liquid is a liquid that can react with the harmful substances in the waste gas. Finally, it is sprayed downward onto the corresponding packing filter layer 12 through each spray head 11. When the waste gas passes through the packing filter layer 12, the harmful substances in the waste gas come into contact and react with the spraying liquid in the packing filter layer 12, thereby removing the harmful substances in the waste gas. The purified gas finally discharges through the exhaust pipe 14, and the sewage in the treatment barrel 1 discharges through the sewage discharge pipe 15.

10. An exhaust gas separation and treatment method for rubber auxiliaries production, characterized in that: Adopt the waste gas separation and treatment equipment for rubber auxiliary production as described in claim 4. The method includes the following steps: Step 1: Pass the high-temperature waste gas generated in the rubber auxiliary production process into the heat preservation cylinder (51) through the air inlet pipe (510). At the same time, use an external pump to pass external cold water into each first heat exchange tube assembly (57) and each second heat exchange tube assembly (58) through the water injection pipe (512) and the left disc cover (511). During the process of the water flow entering the left disc cover (511), it impacts the impeller (56) to make it rotate, and the driving gear (55) rotates accordingly. Then the cold water flows to the right through the inside of the first heat exchange tube assembly (57) and the second heat exchange tube assembly (58). At the same time, the high-temperature waste gas entering the heat preservation cylinder (51) is in contact with the outer walls of the first heat exchange tube assembly (57) and the second heat exchange tube assembly (58). The high-temperature waste gas transfers heat to the water in the first heat exchange tube assembly (57) and the second heat exchange tube assembly (58) through the first heat exchange tube assembly (57) and the second heat exchange tube assembly (58), increasing the water temperature and decreasing the waste gas temperature for heat exchange; Step 2: After the particulate matter in the waste gas is cooled, under the action of gravity, it deposits on the outer walls of the first heat exchange tube assembly (57) and the second heat exchange tube assembly (58). Since the driving gear (55) rotates and drives the first heat exchange tube assembly (57) and the second heat exchange tube assembly (58) to scrape their own outer walls, the particulate matter deposited on the outer walls of the first heat exchange tube assembly (57) and the second heat exchange tube assembly (58) is scraped off in time, and the scraped particulate matter falls into the slag collection box (515); Step 3: Under the action of the upper second heat exchange tube assembly (58), the inside of the air outlet elbow assembly (59) is intermittently opened, so that the waste gas enters the treatment barrel (1) through the air outlet elbow assembly (59) after sufficient heat exchange. The waste gas passes through the two packing filter layers (12) from bottom to top in the treatment barrel (1). During this process, due to the operation of the water pump (7), the external spraying liquid is sucked into the drain pipe (8), the branch pipe (9) and the annular pipe (10) through the water suction pipe (13), and finally sprayed downward onto the corresponding packing filter layer (12) through each nozzle (11). When the waste gas passes through the packing filter layer (12), the harmful substances in the waste gas contact and react with the spraying liquid in the packing filter layer (12), thereby removing the harmful substances in the waste gas. The purified gas is finally discharged through the exhaust pipe (14), and the sewage in the treatment barrel (1) is discharged through the sewage discharge pipe (15).
