Abstract

The present invention discloses waste gas separation and treatment equipment and methods for use in rubber chemical production, and relates to the technical field of waste gas separation and treatment. The waste gas separation and treatment method for use in rubber chemical production utilizes the interaction between a driving gear, an impeller, a first heat exchange tube assembly, and a second heat exchange tube assembly. Water flowing into a left disc cover impacts the impeller, causing it to rotate, which in turn drives the first and second heat exchange tube assemblies to operate, enabling the first and second heat exchange tube assemblies to achieve self-cleaning, thereby preventing the heat exchange efficiency from being affected by deposited particulate matter. During operation, the first and second heat exchange tube assemblies can also promptly disturb the waste gas within the insulation tube, allowing the waste gas within the insulation tube to fully contact the outer walls of the first and second heat exchange tube assemblies, further improving the heat exchange efficiency.

[0016] The present invention also provides a waste gas separation and treatment method for the production of rubber chemicals, which uses waste gas separation and treatment equipment for the production of rubber chemicals. The specific method includes the following steps:

[0017] Step 1: The high-temperature exhaust gas generated during the production of rubber chemicals is introduced into the insulation cylinder through the air inlet pipe. At the same time, an external pump body is used to pass external cold water into each first heat exchange tube assembly and each second heat exchange tube assembly through the water injection pipe and the left disc cover. In the process of water flowing into the left disc cover, it impacts the impeller to rotate, and the driving gear rotates accordingly. Then, the cold water flows to the right through the interior of the first heat exchange tube assembly and the second heat exchange tube assembly. At the same time, the high-temperature exhaust gas entering the insulation cylinder contacts the outer walls of the first heat exchange tube assembly and the second heat exchange tube assembly. The high-temperature exhaust gas transfers heat to the water in the first heat exchange tube assembly and the second heat exchange tube assembly through the first heat exchange tube assembly and the second heat exchange tube assembly, thereby increasing the water temperature and reducing the exhaust gas temperature, thereby performing heat exchange.

[0018] Step 2: After the particulate matter in the exhaust gas is cooled, it is deposited on the outer walls of the first heat exchange tube assembly and the second heat exchange tube assembly under the action of gravity. As the driving gear rotates, the first heat exchange tube assembly and the second heat exchange tube assembly are driven to scrape their own outer walls, so that the particulate matter deposited on the outer walls of the first heat exchange tube assembly and the second heat exchange tube assembly are scraped off in time, and the scraped particulate matter falls into the slag collecting box;

[0019] Step three: under the action of the second upper heat exchange tube assembly, the interior of the air outlet elbow assembly is intermittently opened, so that the exhaust gas completes sufficient heat exchange and then enters the treatment barrel through the air outlet elbow assembly. The exhaust gas passes through the two packing filter layers from bottom to top in the treatment barrel. During the process, due to the operation of the water pump, the external spray liquid is sucked into the drain pipe, branch pipe and annular pipe through the suction pipe, and finally sprayed downward onto the corresponding packing filter layer through each nozzle. When the exhaust gas passes through the packing filter layer, the harmful substances in the exhaust gas contact and react with the spray liquid in the packing filter layer, thereby removing the harmful substances in the exhaust gas. The purified gas is finally discharged through the exhaust pipe, and the sewage in the treatment barrel is discharged through the sewage pipe. Beneficial effects

[0020] The present invention provides waste gas separation and treatment equipment and methods for use in rubber additive production. Compared with the prior art, it has the following advantages:

[0021] 1. The waste gas separation and treatment equipment and method used in the production of rubber additives, through the mutual cooperation between the insulation tube, the first heat exchange tube assembly, the second heat exchange tube assembly and the air outlet elbow assembly, allows the high-temperature waste gas to enter the insulation tube before entering the treatment barrel, and exchange heat with the cold water in the first heat exchange tube assembly and the second heat exchange tube assembly. At the same time, under the action of the upper second heat exchange tube assembly, the interior of the air outlet elbow assembly is intermittently opened, extending the time the waste gas stays in the insulation tube, improving the heat exchange efficiency, and allowing the waste gas to complete sufficient heat exchange before entering the treatment barrel through the air outlet elbow assembly, thereby fully recovering and reusing the heat in the high-temperature waste gas, and then removing harmful substances in the waste gas.

[0022] 2. Waste gas separation and treatment equipment and method for the production of rubber additives. Through the mutual cooperation between the driving gear, impeller, first gear ring, first spiral scraper, second gear ring and second spiral scraper, water flow entering the left disc cover will impact the impeller to rotate, and the driving gear will rotate accordingly, thereby driving the first gear ring, the first spiral scraper, the second gear ring and the second spiral scraper to rotate. During the rotation process, the first spiral scraper and the second spiral scraper can automatically and timely clean the outer wall of the copper tube, and promptly scrape off the particles in the exhaust gas that fall on the outer wall of the copper tube due to cold, so as to prevent the outer wall of the copper tube from affecting the heat exchange efficiency due to the deposition of particles. Through the arrangement of the first spoiler blade and the second spoiler blade, as the first spiral scraper and the second spiral scraper rotate, the first spoiler blades and the second spoiler blades also rotate. During the rotation of the first spoiler blade and the second spoiler blade, the exhaust gas in the insulation tube is disturbed, so that the exhaust gas in the insulation tube fully contacts the outer wall of the copper tube, further improving the heat exchange efficiency.

[0023] 3. The waste gas separation and treatment equipment and method used in the production of rubber additives, through the mutual cooperation between the trapezoidal protrusion, the containing tube, the support rod, the stopper, the second semicircular block and the third spring, the corresponding ring and the corresponding trapezoidal protrusion are driven to rotate during the rotation of the upper second spiral scraper. During the rotation of the trapezoidal protrusion, it will contact the bottom of the second semicircular block, and then intermittently push the stopper to move upward, so that the waste gas in the insulation cylinder is discharged upward through the gap between the stopper and the containing tube and enters the treatment barrel. Since the interior of the air outlet elbow assembly is intermittently opened, the time the waste gas stays in the insulation cylinder is extended, so that the high-temperature waste gas and water can fully exchange heat.

[0024] 4. Waste gas separation and treatment equipment and method used in the production of rubber additives. Through the mutual cooperation between the trapezoidal protrusion, the first semicircular block, the first wedge block, the second wedge block and the push plate, the corresponding collar and the corresponding trapezoidal protrusion are driven to rotate during the rotation of the lower second spiral scraper. During the rotation of the trapezoidal protrusion, it will contact the top of the first semicircular 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 the left, realizing intermittent pushing of the push plate. Under the action of the intermittent pushing, the push plate pushes the particles that fall into the collection bin to the left, so that the originally dispersed particles gradually accumulate together, providing convenience for subsequent rapid cleaning work.

Through the mutual cooperation between the trapezoidal protrusion 587, the accommodating tube 592, the support rod 595, the stopper 596, the second semicircular block 597 and the third spring 598, the upper During the rotation of the second spiral scraper 584, the corresponding collar 586 and the corresponding trapezoidal protrusion 587 are driven to rotate. During the rotation of the trapezoidal protrusion 587, it will contact the bottom of the second semicircular block 597, and then intermittently push the stopper 596 to move upward, so that the exhaust gas in the insulation cylinder 51 is discharged upward through the gap between the stopper 596 and the receiving tube 592 and enters the treatment barrel 1. Since the interior of the air outlet elbow assembly 59 is intermittently opened, the time the exhaust gas stays in the insulation cylinder 51 is prolonged, so that the high-temperature exhaust gas and water can fully exchange heat. Through the trapezoidal protrusion 587, the first semicircular block 520, the first wedge block 521, the second wedge block 524 and the push The plates 525 cooperate with each other, and the second spiral scraper rod 584 at the bottom rotates, which drives the corresponding collar 586 and the corresponding trapezoidal protrusion 587 to rotate. During the rotation of the trapezoidal protrusion 587, it will contact the top of the first semicircular 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 to the left, realizing the intermittent push of the push plate 525. Under the action of the intermittent push, the push plate 525 pushes the particles that fall into the collection bin 515 to the left, so that the originally scattered particles gradually accumulate together, providing convenience for subsequent rapid cleaning work.

[0047] The embodiment of the present invention further provides a method for separating and treating waste gas used in the production of rubber additives, using waste gas separation and treatment equipment used in the production of rubber additives. The specific method includes the following steps:

[0048] Step 1: The high-temperature exhaust gas generated during the production of rubber chemicals is introduced into the insulation cylinder 51 through the air inlet pipe 510. At the same time, an external pump body is used to pass external cold water into each first copper tube 571 and each second copper tube 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 rotate, and the driving gear 55 rotates accordingly. Then, the cold water flows to the right through the inside of the first copper tube 571 and the second copper tube 581. At the same time, the high-temperature exhaust gas entering the insulation cylinder 51 contacts the outer walls of the first copper tube 571 and the second copper tube 581. The high-temperature exhaust gas transfers heat to the water in the first copper tube 571 and the second copper tube 581 through the first copper tube 571 and the second copper tube 581, thereby increasing the water temperature and reducing the exhaust gas temperature. Heat exchange is performed, and the heated water flows out from each copper tube through the right water inlet 52, and finally passes through the inside of the right disc cover 513 and the outlet pipe 514 and flows to a designated location outside.

[0049] Step 2: After the particulate matter in the exhaust gas is cooled, it is deposited on the outer walls of the first copper tube 571 and the second copper tube 581 under the action of gravity. Since the driving gear 55 rotates and drives the first gear ring 573, the first spiral scraper 574, the second gear ring 583 and the second spiral scraper 584 to rotate, the first spiral scraper 574 and the second spiral scraper 584 automatically and timely scrape the outer walls of the copper tubes during the rotation process, and promptly scrape off the particulate matter in the exhaust gas that has fallen on the outer walls of the copper tubes due to the cooling. The scraped particles fall into the slag collecting box 515;

[0050] Step three, under the action of the upper second heat exchange tube assembly 58, the interior of the air outlet elbow assembly 59 is intermittently opened, so that the exhaust gas completes sufficient heat exchange and then enters the treatment barrel 1 through the air outlet elbow assembly 59. The exhaust gas passes through the two packing filter layers 12 from bottom to top in the treatment barrel 1. During the process, due to the operation of the water pump 7, the external spray liquid is sucked into the drain pipe 8, the branch pipe 9 and the annular pipe 10 through the suction pipe 13, wherein the spray liquid is a liquid that can react with harmful substances in the exhaust gas, and is finally sprayed downward onto the corresponding packing filter layer 12 through each nozzle 11. When the exhaust gas passes through the packing filter layer 12, the harmful substances in the exhaust gas contact and react with the spray liquid in the packing filter layer 12, thereby removing the harmful substances in the exhaust 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 pipe 15.
