Description

Technical Field

[0002] With the advancement of science and technology and the development of mankind, the development of the chemical industry has also been greatly enhanced, resulting in more and more chemical plants and larger and larger scales. The increase and expansion of chemical plants has brought about a large amount of chemical exhaust gas emissions. Chemical exhaust gas refers to toxic and harmful gases discharged by chemical plants during chemical production. Chemical exhaust gas often contains many types of pollutants with complex physical and chemical properties and different toxicity. It seriously pollutes the environment and affects human health, and then causes diseases and even death of animals, plants and personnel. Therefore, it is necessary to treat the chemical exhaust gas. Only after the exhaust gas meets the standards for external exhaust gas emissions can it be discharged to reduce environmental pollution.

[0004] Although the technical solution in the above patent document fully contacts the chemical exhaust gas with the absorption liquid, and then assists with the adsorption effect of activated carbon particles to achieve the purification of the chemical exhaust gas, in actual use, since the exhaust gas contains a large amount of impurities, the method of directly passing the chemical exhaust gas into the purification cylinder for contact with the absorption liquid is not only difficult to ensure the treatment effect of the chemical exhaust gas, but also when the chemical exhaust gas containing a large amount of impurities passes through the pipeline for a long time, the impurities in the chemical exhaust gas will be deposited on the inner wall of the pipeline, especially at the release port of the chemical exhaust gas, which is very easy to contact with the absorption liquid for treating the chemical exhaust gas, and then the deposition effect of the impurities on the port will be aggravated, causing the port to be blocked, thereby affecting the treatment efficiency of the chemical exhaust gas and wasting the absorption liquid resources.

[0014] The technical solution of the second aspect: a method for using an environmentally friendly tail gas treatment device for chemical production, the method comprising the following steps: Step 1: The equipment is pre-operated. The water pump body is first turned on through the external controller body. The water pump body extracts the absorption liquid stored externally and pumps it into the spray mechanism. The absorption liquid is sprayed from the spray mechanism to the inside of the treatment barrel. Then the motor in the pre-treatment mechanism is started. The motor drives the impeller to move and simultaneously makes the transmission shaft move. The cleaning component reciprocates through the bending rod. The transmission shaft drives the worm to move through the toothed chain part 1 when rotating. The worm and the worm wheel in the jet mechanism are meshed and driven, so that the jet mechanism rotates as a whole. The jet mechanism and the spray mechanism are plugged and assembled, so as to synchronously drive the spray mechanism to rotate; Step 2: exhaust gas pretreatment, connecting the chemical exhaust gas to the air inlet pipe in the pretreatment mechanism, the chemical exhaust gas enters the interior of the shell along the air inlet pipe, and then passes through multiple filter screens, and enters the air guide pipe in the jet mechanism under the action of the rotating impeller; Step 3: Release of tail gas. The tail gas entering the air guide pipe is released from the ports on each branch pipe in the jet component. Since the ports on each branch pipe are located below the liquid surface of the absorption liquid at this time, the tail gas directly contacts the absorption liquid after being released. At this time, the jet mechanism performs a rotating motion to synchronously stir the absorption liquid to ensure uniform contact between the tail gas and the absorption liquid. Step 4: Intermittent discharge of waste liquid. The rotation of the air guide pipe synchronously drives the special-shaped column to move. The special-shaped column intermittently contacts the adjustment rod in the discharge mechanism during the rotation. When the adjustment rod contacts the inclined surface of the special-shaped column, as the special-shaped column rotates, the adjustment rod drives the integration plate to move downward, so that the lifting rod pulls the blocking ring downward. After the blocking ring moves downward, the sealing plug on it cancels the blockage of the discharge hole, so that the absorption liquid stored in the treatment barrel enters the shell cover from the discharge hole. After the blocking ring moves down to the bottom of the sewage pipe, the waste liquid is automatically discharged through the sewage pipe. When the adjustment rod cancels the contact with the special-shaped column, the blocking ring and the integration plate are reset under the action of the reset spring, and the blocking ring realizes the blocking of the discharge hole again. After the integration plate is reset, the multiple knocking rods on it knock on the bottom shell wall of the treatment barrel to make it vibrate. Step 5: Self-cleaning of the jet mechanism. The spray mechanism rotates synchronously with the movement of the jet mechanism, and then performs rotational spraying of the absorption liquid inside the treatment barrel, and sprays the gas that has passed through the absorption liquid again. When the spray mechanism rotates, the L-shaped scraper moves synchronously to scrape the sediment on the bottom inner wall of the treatment barrel, and the movement of the reciprocating screw rod causes the lifting member to drive the base ring to perform longitudinal reciprocating lifting movement. The base ring causes the cleaning component to perform reciprocating lifting movement through the traction rod. When the cleaning component moves upward, each brush roller extends into the corresponding port, and during the upward movement of the cleaning component, each contact rod moves on the round table under the action of the corresponding extrusion spring, and then the corresponding displacement plate drives the second toothed chain member to move, so that each brush roller rotates. When the cleaning component moves downward, each brush roller extends out from the corresponding port in a rotational manner, thereby realizing rotational self-cleaning of each corresponding port. Step 6: Gas discharge. The gas treated by spraying rises and is preheated when passing through the area where the heat conductive wire is located. Then it enters the adsorption plate for filtration and dehumidification, and finally is discharged from the release pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a pretreatment mechanism to pre-filter the chemical exhaust gas to be treated, the content of impurities in the chemical exhaust gas entering the treatment barrel can be reduced, the risk of clogging the pipeline for transporting the chemical exhaust gas can be reduced, the treatment efficiency of the chemical exhaust gas can be guaranteed, and the waste of absorption liquid resources can be avoided.

[0016] 2. In the pretreatment mechanism, a motor is set to drive the impeller to run, thereby accelerating the gas passing through multiple filters into the treatment barrel, further improving the treatment efficiency of chemical exhaust gas, and the impeller movement will simultaneously drive the cleaning component to realize automatic cleaning of the multiple filters, thereby extending the service life of the filters and reducing the burden of manual maintenance of the filters. In the process of movement, the impeller drives the worm to rotate through the toothed chain, thereby making the jet mechanism equipped with a worm gear move synchronously.

[0017] 3. The jet mechanism installed in the treatment barrel rotates and discharges the filtered chemical exhaust gas during its activity. The chemical exhaust gas discharged from the jet mechanism directly enters the absorption liquid stored in the treatment barrel, realizing direct contact with the absorption liquid, ensuring the uniformity of the treatment of the chemical exhaust gas, and the rotating movement of the jet mechanism will stir the absorption liquid in the storage state, further ensuring the uniformity of the contact between the chemical exhaust gas and the absorption liquid, and improving the utilization rate of the absorption liquid.

[0018] 4. The spray mechanism arranged above the jet mechanism is plugged and assembled with the jet mechanism, and then moves synchronously when the jet mechanism moves, so as to realize the second absorption liquid spraying treatment of the exhaust gas that has passed through the absorption liquid, on the one hand to realize the replenishment of the absorption liquid in the treatment barrel, on the other hand to further treat the exhaust gas.

[0019] 5. When the jet mechanism rotates, the unloading mechanism will make intermittent movement, and then the absorption liquid stored in the treatment barrel will be discharged intermittently, so as to avoid the absorption liquid being stored too high and affecting the spraying mechanism. The absorption liquid always reaches a dynamic balance in the treatment barrel under the discharge action of the unloading mechanism and the supplementary action of the spraying mechanism, thus avoiding the waste of resources while ensuring the treatment effect of chemical exhaust gas.

[0020] 6. The cooperation between the jet mechanism and the spray mechanism can achieve deep self-cleaning of the port for releasing gas in the spray mechanism, avoiding the blockage of the port caused by the deposition of impurities in the chemical exhaust gas, and further ensuring the efficiency of chemical exhaust gas treatment.

[0021] 7. By setting up the heat-conducting wire, the waste heat in the chemical tail gas can be utilized, so as to preheat the gas after spraying, and then through the combination of adsorption plates, the dehumidification effect of the discharged gas can be achieved.

[0045] A worm 79 is provided above the housing 71, and two support frames are sleeved on the worm 79, and the bottom of the support frame is fixedly connected to the outer wall of the housing 71 by bolts. The worm 79 is meshed with the worm wheel 54 to drive the jet mechanism 5 to rotate synchronously. The transmission shaft 76 and the worm 79 are linked by a toothed chain member 78. The toothed chain member 78 is composed of a sprocket wheel 1 and a chain 1, wherein the sprocket wheel 1 includes two, which are respectively mounted on the transmission shaft 76 and the worm 79, and the two sprocket wheels 1 are connected by a chain 1.

[0046] The filter screen 73 includes a plurality of filters which are linearly arranged inside the housing 71, and the top of the filter screen 73 passes through the top shell wall of the housing 71, and the filter screen 73 is disassembled and maintained. The cleaning assembly 74 includes a plurality of slide bars 741 located inside the housing 71, and the two ends of the slide bars 741 respectively penetrate the corresponding shell walls of the housing 71. The front and rear ends of the plurality of slide bars 741 are respectively installed with end plates 742, and each slide bar 741 is linearly distributed with a plurality of cleaning plates 743 for wiping the corresponding filter screen 73.

Before using the pretreatment mechanism 7, a certain amount of water resources can be poured into the storage chamber, so that the cleaned impurities are not easily blown up again by the airflow after falling into the storage chamber, which is also convenient for subsequent cleaning of the storage chamber.

[0047] The outer surface of the transmission shaft 76 is provided with an arc-shaped closed groove, in which a convex rod is slidably connected, and a moving ring is also sleeved on the transmission shaft 76. The end of the convex rod away from the arc-shaped closed groove is fixedly connected to the inner shell wall of the moving ring, and then when the transmission shaft 76 rotates, the movement of the convex rod in the arc-shaped closed groove causes the moving ring to perform reciprocating displacement adjustment.

The setting of the bent rod 77 allows the movement of the moving ring to drive the cleaning assembly 74 to move, and also ensures the stability of the linear movement of the moving ring.

[0048] The heat conducting wire 8 includes a small coiled portion, a conduction portion and a large coiled portion. The small coiled portion is located on the air intake pipe, thereby utilizing the heat of the chemical exhaust gas entering the air intake pipe. The large coiled portion is located on the inner wall of the barrel 11 and between the adsorption disk 3 and the object carrier 14. The small coiled portion and the large coiled portion are connected by the conduction portion. The waste heat of the chemical exhaust gas is utilized by the setting of the heat conducting wire 8 to achieve preheating of the gas after the spraying treatment.

[0049] The present invention provides a method for using an environmentally friendly tail gas treatment device for chemical production, the method comprising the following steps: Step 1: The equipment is pre-operated. The water pump body 9 is first turned on through the external controller body. The water pump body 9 extracts the externally stored absorption liquid and pumps it into the spray mechanism 6. The absorption liquid is sprayed from the spray mechanism 6 into the processing barrel 1 for storage. When the control program in the controller body is running, the motor 75 in the pre-treatment mechanism 7 is started again when the absorption liquid is stored in the processing barrel 1 to a certain depth.

[0050] The motor 75 drives the impeller 72 to move, and synchronously moves the transmission shaft 76. When the transmission shaft 76 rotates, the movable ring movably connected thereto moves back and forth under the action of the protruding rod, and then the cleaning assembly 74 moves back and forth through the bent rod 77. The cleaning assembly 74 wipes and cleans the corresponding filter screen 73 in the pretreatment mechanism 7 under the reciprocating motion. When the transmission shaft 76 rotates, the worm 79 is driven to move through the toothed chain member 1 78, and the worm 79 is meshed with the worm wheel 54 in the jet mechanism 5, so that the jet mechanism 5 rotates as a whole. The jet mechanism 5 is plugged and assembled with the spray mechanism 6, so as to synchronously drive the spray mechanism 6 to rotate.

[0051] Step 2: Pretreatment of tail gas: connect the chemical tail gas to the air inlet pipe in the pretreatment mechanism 7, and the chemical tail gas enters the interior of the housing 71 along the air inlet pipe. The chemical tail gas entering the housing 71 needs to pass through the multiple filter screens 73, so as to filter the large particles of impurities mixed in the chemical tail gas. The impeller 72 rotates under the drive of the motor 75, and its rotating blasting function realizes the transportation of the preliminarily filtered tail gas, so that the tail gas can quickly enter the air guide pipe 52 in the jet mechanism 5.

[0052] Step 3: Release of tail gas: the tail gas entering the air guide pipe 52 is released from the ports on each branch pipe in the jet member 51. Since the ports on each branch pipe are all located below the liquid surface of the absorption liquid, the tail gas directly contacts the absorption liquid after being released. At this time, the jet mechanism 5 performs a rotational motion, synchronously stirring the absorption liquid to ensure uniform contact between the tail gas and the absorption liquid.

[0053] Step 4: Intermittent discharge of waste liquid, the rotation of the air guide pipe 52 synchronously drives the special-shaped column 53 to move. The special-shaped column 53 intermittently contacts the adjustment rod 46 in the discharge mechanism 4 during the rotation process. When the adjustment rod 46 contacts the inclined surface of the special-shaped column 53, as the special-shaped column 53 rotates, the adjustment rod 46 drives the integration plate 44 to move downward, so that the lifting rod 43 pulls the blocking ring 42 to move downward.

[0054] After the blocking ring 42 moves down, the sealing plug on it cancels the blockage of the discharge hole, so that the absorption liquid stored in the treatment barrel 1 enters the shell cover 41 from the discharge hole. After the blocking ring 42 moves down to the bottom of the sewage pipe, the waste liquid is automatically discharged through the sewage pipe. When the adjustment rod 46 and the special-shaped column 53 are no longer in contact, the blocking ring 42 and the integration plate 44 are reset under the action of the reset spring. The blocking ring 42 blocks the discharge hole again, and after the integration plate 44 is reset, the multiple knocking rods 45 on it knock the bottom shell wall of the treatment barrel 1, causing it to vibrate, thereby loosening the sediment on the bottom inner wall of the treatment barrel 1 for subsequent discharge and cleaning.

[0055] Step 5: Self-cleaning of the jet mechanism 5. The spray mechanism 6 rotates synchronously with the movement of the jet mechanism 5, and then performs a rotary spray of the absorption liquid inside the treatment barrel 1, and performs a second spray treatment on the gas that has passed through the absorption liquid. When the spray mechanism 6 rotates, the L-shaped scraper 66 moves synchronously to scrape the sediment on the bottom inner wall of the treatment barrel 1, thereby further improving the self-cleaning effect inside the treatment barrel 1 when the waste liquid is discharged.

[0056] The movement of the reciprocating screw 64 enables the lifting member 65 to drive the base ring 57 to perform longitudinal reciprocating lifting movement. The base ring 57 enables the cleaning assembly 55 to perform reciprocating lifting movement through the traction rod 56. When the cleaning assembly 55 moves upward, each brush roller 552 extends into the corresponding port, and during the upward movement of the cleaning assembly 55, each contact rod 556 moves on the round table 2 under the action of the corresponding extrusion spring. Then the corresponding displacement plate 554 drives the toothed chain member 2 553 to move, so that each brush roller 552 rotates. When the cleaning assembly 55 moves downward, each brush roller 552 extends out from the corresponding port in a rotational manner, thereby realizing the rotational self-cleaning of each corresponding port.

[0057] Step 6: Gas discharge. The gas treated by spraying rises and is preheated when passing through the area where the heat conducting wire 8 is located. Then, it enters the adsorption disk 3 for filtration and dehumidification, and finally is discharged from the release pipe.

[0058] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

9. A method for using an environmentally friendly tail gas treatment device for chemical production according to any one of claims 1 to 8, characterized in that: The method comprises the following steps: Step 1: The equipment is pre-operated. The water pump body (9) is first turned on through the external controller body. The water pump body (9) extracts the absorption liquid stored externally and pumps it into the spray mechanism (6). The absorption liquid is sprayed from the spray mechanism (6) into the interior of the treatment barrel (1). Then, the motor (75) in the pre-treatment mechanism (7) is started. The motor (75) drives the impeller (72) to move and simultaneously moves the transmission shaft (76). The cleaning component (74) is reciprocated through the bent rod (77). The transmission shaft (76) drives the worm (79) to move through the toothed chain member (78) in the case of rotation. The worm (79) and the worm wheel (54) in the jet mechanism (5) are meshed and driven, thereby causing the jet mechanism (5) to rotate as a whole. The jet mechanism (5) and the spray mechanism (6) are plugged and assembled, thereby synchronously driving the spray mechanism (6) to rotate. Step 2: pre-treatment of the exhaust gas, connecting the chemical exhaust gas to the air inlet pipe in the pre-treatment mechanism (7), the chemical exhaust gas enters the interior of the housing (71) along the air inlet pipe, and then passes through the multiple filter screens (73), and then enters the air guide pipe (52) in the jet mechanism (5) under the action of the rotating blast of the impeller (72); Step 3: releasing the tail gas. The tail gas entering the air guide pipe (52) is released from the ports on each branch pipe in the jetting member (51). Since the ports on each branch pipe are located below the liquid surface of the absorption liquid at this time, the tail gas directly contacts the absorption liquid after being released. At this time, the jetting mechanism (5) performs a rotational motion to synchronously stir the absorption liquid, thereby ensuring uniform contact between the tail gas and the absorption liquid. Step 4: Intermittent discharge of waste liquid. The rotation of the air guide pipe (52) synchronously drives the special-shaped column (53) to move. The special-shaped column (53) intermittently contacts the adjustment rod (46) in the discharge mechanism (4) during the rotation process. When the adjustment rod (46) contacts the inclined surface of the special-shaped column (53), as the special-shaped column (53) rotates, the adjustment rod (46) drives the integration plate (44) to move downward, so that the lifting rod (43) pulls the blocking ring (42) downward. After the blocking ring (42) moves downward, the sealing plug on it cancels the discharge hole. The blockage allows the absorption liquid stored in the treatment barrel (1) to enter the shell cover (41) from the discharge hole. After the blocking ring (42) moves down to the bottom of the sewage pipe, the waste liquid is automatically discharged through the sewage pipe. When the adjustment rod (46) and the special-shaped column (53) are no longer in contact, the blocking ring (42) and the integration plate (44) are reset under the action of the reset spring, and the blocking ring (42) blocks the discharge hole again. After the integration plate (44) is reset, the multiple knocking rods (45) on it knock on the bottom shell wall of the treatment barrel (1), causing it to vibrate. Step 5: The jet mechanism (5) is self-cleaned. The spray mechanism (6) rotates synchronously with the movement of the jet mechanism (5), and then performs a rotational spray of the absorption liquid inside the treatment barrel (1), and the gas that has passed through the absorption liquid is sprayed again. When the spray mechanism (6) rotates, the L-shaped scraper (66) moves synchronously to scrape the sediment on the bottom inner wall of the treatment barrel (1). The movement of the reciprocating screw (64) causes the lifting member (65) to drive the base ring (57) to perform a longitudinal reciprocating lifting movement. The base ring (57) is driven by the traction rod (56). The cleaning assembly (55) performs reciprocating lifting motion. When the cleaning assembly (55) moves upward, each brush roller (552) extends into the corresponding port. In the process of the cleaning assembly (55) moving upward, each contact rod (556) moves on the round table (2) under the action of the corresponding extrusion spring, and then the corresponding displacement plate (554) drives the second toothed chain member (553) to move, so that each brush roller (552) rotates. When the cleaning assembly (55) moves downward, each brush roller (552) extends out from the corresponding port in a rotational manner, thereby realizing rotational self-cleaning of each corresponding port. Step 6: Gas discharge. The gas treated by spraying rises and is preheated when passing through the area where the heat conducting wire (8) is located. It then enters the adsorption disk (3) for filtration and dehumidification, and is finally discharged from the release pipe.
