Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and in particular is a combined treatment system suitable for waste gas in the natural rubber industry. Background Art

[0002] Natural rubber is natural latex collected from rubber trees. Natural rubber is a natural high molecular compound with cis-1, 4-polyisoprene as the main component, and its rubber hydrocarbon (cis-1, 4-polyisoprene) content is more than 90%. The collected natural rubber is usually processed through centralized aging, thinning, sheeting, granulation, packaging, and drying. The process from collection to processing of natural rubber is always accompanied by VOCs pollution, including alcohols, aldehydes, esters, fatty acids, as well as amines, ketones, ethers, aromatic hydrocarbons and other VOCs.

[0003] In the prior art, the waste gas after natural rubber treatment is centrally treated through a combined treatment system, including a washing and cooling tower, an integrated biological treatment equipment, a dehydration adsorption box, an activated carbon adsorption and desorption section, etc., wherein the washing tower can absorb or dissolve the particulate matter and some gaseous pollutants in the waste gas. However, with the recycling of washing water, the particulate matter, gaseous pollutants, etc. in the waste gas will gradually accumulate in the washing water, resulting in a gradual decrease in the purification capacity of the washing water. When the pollutant concentration in the washing water reaches a certain level, the washing water will reach a saturated state, thereby reducing the waste gas treatment capacity.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1: Figures 1 to 8 As shown, a combined treatment system for waste gas in the natural rubber industry according to an embodiment of the present invention comprises a spray tower 1, an integrated biological treatment device 2, an activated carbon adsorption device 3, a catalytic oxidation furnace 4 and an exhaust pipe 5, and a water pipe 7 and a waste gas inlet pipe 6 are provided on the spray tower 1;

[0038] The waste gas enters the spray tower 1 through the waste gas inlet pipe 6 and is first cooled. After entering the spray tower 1, the washing liquid cools the waste gas from bottom to top from top to bottom. During the cooling process, the harmful substances are absorbed by the gas-liquid contact to produce water reaction, so that the harmful gaseous components are converted into liquid or harmless gas (the necessary pipes, valves, pressure gauges, thermometers, and continuous water inlet and outlet pipelines for washing are required).

[0039] The cooled exhaust gas enters the integrated biological treatment equipment 2, the interior of which is filled with a proportioned filler specially used in the natural rubber industry (this is a technical means well known to those skilled in the art and will not be elaborated on here). After passing through the filler, the exhaust gas is discharged from the integrated biological treatment equipment 2 and the demister tower to the activated carbon adsorption equipment 3 at the rear end.

[0040] The activated carbon adsorption equipment 3 is mainly used to adsorb and treat hydrocarbon odorous substances that cannot be completely treated by the integrated biological treatment equipment 2. There are multiple activated carbon adsorption equipment 3, and multiple activated carbon adsorption equipment 3 share a collective pipeline system, which is equipped with valves required for system operation. They can be switched with each other during operation. In normal operating state, there are multiple activated carbon adsorption equipment 3, and another activated carbon adsorption equipment 3 is in regeneration or static. When one of the activated carbon adsorption equipment 3 is saturated with adsorption, it needs to be regenerated and cooled.

[0041] After the activated carbon adsorption device 3 is saturated with adsorption, it needs to be desorbed and regenerated before it can be reused (this is a technical means well known to those skilled in the art and will not be elaborated on here).

[0042] The catalytic oxidation furnace 4 heats the gas to about 250-350°C, and the organic matter in the gas is decomposed into and The purification efficiency of the combustion and decomposition process can reach more than 98%, and a large amount of heat is released at the same time. The gas after combustion and decomposition is discharged into the atmosphere through the exhaust pipe 5. The whole set of adsorption and combustion and decomposition processes are automatically controlled by PLC (all of which are well-known technical means for those skilled in the art, so I will not go into details here).

[0043] A first processing ring 17 is slidably installed inside the spray tower 1, a first filter screen 18 is arranged at the top of the first processing ring 17, a second processing ring 20 is detachably installed at the bottom of the first processing ring 17, and a second filter screen 25 is arranged on the second processing ring 20;

[0044] The outer wall of the first processing ring 17 is in contact with the inner wall of the spray tower 1 , and the second processing ring 20 is located below the first processing ring 17 . A certain space is left between the first processing ring 17 and the second processing ring 20 .

[0045] The first processing ring 17 is provided with a cavity, and an atomizing nozzle 36 is provided in the direction of the first processing ring 17 toward the first filter screen 18, and the atomizing nozzle 36 is located between the first filter screen 18 and the second filter screen 25. A water circulation component is provided on one side of the spray tower 1, which is used to collect the water sprayed by the atomizing nozzle 36 and transport it to the inner cavity of the first processing ring 17;

[0046] The atomizing nozzle 36 is arranged above the space between the first processing ring 17 and the second processing ring 20. There are multiple atomizing nozzles 36, and the atomizing nozzles 36 are arranged obliquely downward. There are multiple atomizing nozzles 36, and they are arranged in a ring shape. The washing liquid is transported toward the interior of the spray tower 1 through the water pipe 7. At this time, the washing liquid is transported to the interior of the first processing ring 17 through the water circulation component, and is sprayed out through the atomizing nozzle 36. The sprayed washing liquid will pass through the second filter 25 and flow to the bottom end of the interior of the spray tower 1, and continue to circulate through the water circulation component.

[0047] An exhaust gas guide pipe 35 is provided on the first processing ring 17. One end of the exhaust gas guide pipe 35 extends between the first filter screen 18 and the second filter screen 25 and is located below the atomizing nozzle 36. The other end of the exhaust gas guide pipe 35 is connected to the exhaust gas inlet pipe 6 through the first telescopic pipe 12.

[0048] The waste gas generated by the production of rubber is transported to the first telescopic tube 12 through the waste gas inlet pipe 6, and then transported to the space retained between the first treatment ring 17 and the second treatment ring 20 through the waste gas guide pipe 35. At this time, the particles of the waste gas will be blocked by the first filter 18 and the second filter 25. At the same time, the multiple atomizing nozzles 36 can be set to spray the waste gas downward directly at a close distance to cool the waste gas. At the same time, the gas-liquid contact causes the harmful substances to be absorbed and react with water, so that the harmful gaseous components are converted into liquid or harmless gas. At this time, the particles of the sprayed detergent will fall on the surface of the second filter 25. The first telescopic tube 12 can slide inside the spray tower 1 following the first treatment ring 17. By spraying the waste gas at a close distance, the cooling effect and the effect of the absorbed water reaction of the harmful substances can be improved.

[0049] The spray tower 1 is internally provided with a rotatable air supply blade 15;

[0050] The air supply blades 15 can transport the gas inside the spray tower 1 downward, and by contacting the exhaust gas moving upstream, turbulence can be precipitated inside the spray tower 1, thereby increasing the resistance of the exhaust gas moving upstream, further increasing the time for the atomizing nozzle 36 to spray the exhaust gas, thereby improving efficiency.

[0051] A transmission assembly is provided inside the spray tower 1 to provide power for the sliding of the first processing ring 17 and the rotation of the air supply blades 15 .

[0052] The transmission assembly can be used to control the sliding of the first processing ring 17 inside the spray tower 1 , and can also drive the air supply blades 15 to rotate inside the spray tower 1 .

[0053] The water circulation assembly includes a circulation pump 13, a water supply pipe 14, a water inlet pipe 21 and a second telescopic pipe 16. The circulation pump 13 is arranged on one side of the spray tower 1. One end of the water supply pipe 14 is connected to the output end of the circulation pump 13, and the other end extends to the spray tower 1 and is connected to the inner cavity of the first treatment ring 17 through the second telescopic pipe 16. One end of the water inlet pipe 21 extends to the bottom end of the inner cavity of the spray tower 1, and the other end is connected to the input end of the circulation pump 13.

[0054] When the circulation pump 13 is started, the washing liquid at the bottom of the spray tower 1 can be extracted through the water inlet pipe 21, and then the water is transported to the inside of the second telescopic tube 16 through the water supply pipe 14, and finally enters the inside of the first processing ring 17. At this time, the washing liquid can be sprayed out through the atomizing nozzle 36. The second telescopic tube 16 is set up so that the normal use of the function will not be affected when the first processing ring 17 moves.

[0055] The transmission assembly includes a reciprocating screw rod 11 and a transmission block 19. The reciprocating screw rod 11 is rotatably mounted inside the spray tower 1. The transmission block 19 is fixedly mounted on the first filter screen 18, and the axes coincide with each other. The transmission block 19 is connected to the reciprocating screw rod 11 through threads.

[0056] The air supply blades 15 are fixedly mounted on the outer wall of the reciprocating screw rod 11 .

[0057] Since the first filter 18 is fixedly connected to the first processing ring 17, and the first filter 18 is fixedly connected to the transmission block 19, when the reciprocating screw 11 rotates, it can drive the transmission block 19 to slide back and forth on the outer wall of the reciprocating screw 11, and at the same time drive the second processing ring 20 to move together. At the same time, the reciprocating screw 11 will also drive the air supply blades 15 to rotate, causing turbulence inside the spray tower 1, increasing the resistance of the exhaust gas to float, thereby increasing the exhaust gas spraying time, and further improving the exhaust gas purification and cooling effect.

[0058] A driving motor 8 is fixedly installed at the top of the spray tower 1, and a driving wheel 9 is fixedly installed on the output shaft of the driving motor 8. One end of the reciprocating screw rod 11 extends out of the top of the spray tower 1 and is fixedly installed with a driven wheel 10. The driving wheel 9 and the driven wheel 10 are connected by a belt.

[0059] The driving motor 8 is started to drive the driving wheel 9 to rotate, and the driven wheel 10 is driven to rotate at the same time under the action of the belt, so the reciprocating screw 11 can be controlled to rotate, thereby realizing the control of the sliding of the first processing ring 17.

[0060] An electromagnetic ring 37 is fixedly installed inside the first processing ring 17 , and a bump is provided on the top of the second processing ring 20 and extends to the inside of the first processing ring 17 . The bump can be attracted by the electromagnetic ring 37 through magnetism.

[0061] When the bump on the second processing ring 20 extends to the inside of the first processing ring 17, the bump can be adsorbed by energizing the electromagnetic ring 37, and the second processing ring 20 will be combined with the first processing ring 17. When the electromagnetic ring 37 is powered off, the first processing ring 17 can be separated from the second processing ring 20 by applying a friction force greater than the friction force between the first processing ring 17 and the bump to the second processing ring 20.

[0062] A circulation ring 26 set in the cavity is fixedly installed on the second filter screen 25, and the axis of the circulation ring 26 coincides with the axis of the second filter screen 25. A conducting pipe 29 is fixedly installed at the bottom end of the inner cavity of the spray tower 1. The inner wall of the circulation ring 26 and the outer wall of the conducting pipe 29 are slidably plugged. A drain port 38 is opened on the inner wall of the circulation ring 26, and a water inlet 39 is opened on the outer wall of the conducting pipe 29. A retaining ring 28 is elastically installed on the outer wall of the conducting pipe 29.

[0063] A hole is provided in the center of the circulation ring 26 for the reciprocating screw 11 to enter, so that the sliding of the first processing ring 17 will not be affected. When the first processing ring 17 is combined with the second processing ring 20, the first processing ring 17 and the second processing ring 20 are controlled by the reciprocating screw 11 to slide to the bottom end of the inner cavity of the spray tower 1 until the circulation ring 26 is plugged into the conducting tube 29 (the friction between the circulation ring 26 and the conducting tube 29 is greater than the friction between the first processing ring 17 and the protrusion). At this time, the electromagnetic ring 37 is powered off, so that the first processing ring 17 and the second processing ring 20 can be separated.

[0064] A pressure spring is arranged between the bottom end of the retaining ring 28 and the bottom end of the spray tower 1. When the circulation ring 26 is plugged into the conducting pipe 29, the retaining ring 28 will be pressed downward. At this time, the retaining ring 28 will slide downward and press the pressure spring to deform it and store elastic potential energy. When the retaining ring 28 slides downward, the obstruction to the water inlet 39 will also be released. At the same time, the drain port 38 opened on the circulation ring 26 will correspond to the water inlet 39. When the first processing ring 17 and the second processing ring 20 need to be combined, when the protrusions on the first processing ring 17 and the second processing ring 20 are plugged in, the electromagnetic ring 37 can be energized to adsorb the protrusions, thereby separating the second processing ring 20 from the conducting pipe 29. At this time, the pressure spring releases the elastic potential energy to reset the retaining ring 28 and block the water inlet 39 again.

[0065] A water pump 22 is provided inside the spray tower 1, and the output end of the water pump 22 is fixedly connected to a drain pipe 24, one end of the drain pipe 24 extends out of the outer wall of the spray tower 1, and the input end of the water pump 22 is fixedly connected to a water suction pipe 23, one end of the water suction pipe 23 extends to the inside of the conducting pipe 29.

[0066] The water pump 22 is connected to the inner cavity of the conducting pipe 29 through the water suction pipe 23, so that the interior of the conducting pipe 29 can be under negative pressure. The other end of the drain pipe 24 can discharge the pumped water. The start of the water pump 22 can be linked with the electromagnetic ring 37. When the electromagnetic ring 37 is powered off, the water pump 22 is started. This technology is well known to those skilled in the art and will not be elaborated on here.

[0067] When the first processing ring 17 drives the second processing ring 20 to approach the conducting tube 29, the electromagnetic ring 37 can be powered off (because the retaining ring 28 has not completely blocked the water inlet 39 during the resetting process, some washing liquid will enter the inner cavity of the conducting tube 29, and even if the water pump 22 is started, there will be no problem of idling and damage). When the electromagnetic ring 37 is powered on, the water pump 22 is powered off.

[0068] A suction pipe 27 is provided on the circulation ring 26 . The suction pipe 27 is L-shaped. One end of the suction pipe 27 opens toward the second filter screen 25 . There are multiple suction pipes 27 . The multiple suction pipes 27 are arranged in an annular shape on the outer wall of the circulation ring 26 .

[0069] The suction pipe 27 is bent downward to reduce the amount of washing liquid entering the interior of the suction pipe 27 when in use. A liquid level gauge is required to be provided inside the spray tower 1 to control the liquid level of the washing liquid in the spray tower 1. The liquid level must not exceed the height of the protrusion on the second processing ring 20 after the second processing ring 20 is connected to the conducting pipe 29. If it exceeds the height, the water supply pipe 7 can be closed.

[0070] Since the first filter 18 and the second filter 25 block the exhaust gas, and the atomizing nozzle 36 sprays toward the second filter 25, the particles in the exhaust gas are retained on the surface of the second filter 25. If they are not processed for a long time, it will affect the passage of water. Therefore, when the second filter 25 needs to be cleaned, the first processing ring 17 is controlled to drive the second processing ring 20 to plug into the conducting pipe 29, and then the first processing ring 17 and the second processing ring 20 can be separated by separating the electromagnetic ring 37 from the protrusion. At this time, the second filter 25 will be located below the liquid surface, and the particles on the second filter 25 can be floated by the buoyancy of the washing liquid. At this time, the start-up of the water pump 22 can make the inner cavity of the conducting pipe 29 present a negative pressure, and cooperate with the suction pipe 27 to suck the washing liquid above the second filter 25, and finally discharge it through the drain pipe 24, which can effectively remove the particles on the second filter 25, while ensuring the filtering effect, reducing the impact of the particles on the water circulation components.

[0071] A swivel 30 is rotatably mounted inside the circulation ring 26 , a plurality of blades 31 are fixedly mounted on the outer wall of the swivel 30 , a water blocking block 32 for blocking the suction pipe 27 is fixedly mounted on the outer wall of the swivel 30 , and a plurality of suction pipes 27 are obliquely arranged on the outer wall of the circulation ring 26 .

[0072] A blocking sheet 33 is elastically installed inside the suction pipe 27 , and the other end of the blocking sheet 33 is fixedly connected to a gravity ball 34 via a connecting rope.

[0073] The blocking piece 33 is installed inside the suction pipe 27 through a torsion spring. The setting of the torsion spring can keep the blocking piece 33 blocking the inner cavity of the suction pipe 27. When the suction pipe 27 sucks the washing liquid, the blocking piece 33 rotates inside the suction pipe 27 under the action of negative pressure to release the blocking of the inner cavity of the suction pipe 27. At the same time, the gravity ball 34 is pulled up by the connecting rope. The inclined suction pipe 27 can guide the flowing washing liquid when sucking the washing liquid, so that the washing liquid is tilted and impacted on the blade 31, so that the rotating ring 30 is The internal rotation of the circulation ring 26, along with the rotation of the rotating ring 30, can drive the water blocking block 32 to rotate, and block the suction pipe 27 in turn. When the water blocking block 32 blocks the opening of one of the suction pipes 27, the suction pipe 27 cannot perform suction at this time. Therefore, the blocking sheet 33 inside the suction pipe 27 is no longer subjected to negative pressure and is reset under the action of the torsion spring. At this time, the gravity ball 34 will fall and hammer the second filter screen 25. The swing of the second filter screen 25 can improve the floating effect of the particles of the second filter screen 25.

[0074] Working principle: the exhaust gas is transported to between the first treatment ring 17 and the second treatment ring 20 through the first telescopic tube 12, and then the circulating pump 13 is started, the water inlet pipe 21 draws the washing liquid at the bottom of the spray tower 1, and the water is transported to the inside of the second telescopic tube 16 through the water supply pipe 14, and finally the washing liquid is sprayed out through the atomizing nozzle 36. The exhaust gas can be sprayed downward directly at a close distance to cool the exhaust gas. At the same time, the gas-liquid contact causes the harmful substances to be absorbed and react with water, so that the harmful gaseous components are converted into liquid or harmless gas, which can improve the exhaust gas purification and cooling effect.

[0075] The first processing ring 17 and the second processing ring 20 are controlled by the reciprocating screw 11 to slide to the bottom end of the inner cavity of the spray tower 1, so that the circulation ring 26 is plugged into the conducting pipe 29, and the first processing ring 17 and the second processing ring 20 are separated by cutting off the power of the electromagnetic ring 37. The particles on the second filter screen 25 can be floated by the buoyancy of the washing liquid. At this time, the start of the water pump 22 can make the inner cavity of the conducting pipe 29 present a negative pressure, and cooperate with the suction pipe 27 to suck the washing liquid above the second filter screen 25, and finally discharge it through the drain pipe 24, which can effectively remove the particles on the second filter screen 25, while ensuring the filtering effect, reducing the impact of the particles on the spray tower 1.

[0076] When the washing liquid is sucked through the suction pipe 27, the blocking piece 33 rotates inside the suction pipe 27 under the action of negative pressure, and the blocking of the inner cavity of the suction pipe 27 is released. At the same time, the gravity ball 34 is pulled up by the connecting rope, and the washing liquid impacts on the blade 31, so that the rotating ring 30 rotates inside the circulation ring 26, which can drive the water blocking block 32 to rotate and block the suction pipe 27 in turn. When the water blocking block 32 blocks the opening of one of the suction pipes 27, the suction pipe 27 cannot be sucked at this time. Therefore, the blocking piece 33 inside the suction pipe 27 is no longer subjected to negative pressure and is reset under the action of the torsion spring. At this time, the gravity ball 34 will fall and hammer the second filter screen 25. The swing of the second filter screen 25 can improve the floating effect of the particles of the second filter screen 25, thereby improving the effect of particle discharge.
