Description

Technical Field

[0001] The invention relates to the technical field of chlorinated paraffin tail gas treatment, and in particular to a chlorinated paraffin tail gas treatment device through absorption. Background Art

[0002] Hydrogen chloride is a colorless gas with a pungent odor. In humid air, it will form white mist. This is because hydrogen chloride is highly soluble in water and combines with water vapor in the air to form small droplets of hydrochloric acid. It is highly corrosive and can irritate and harm the human respiratory tract, eyes and other parts. The production process of chlorinated paraffin will produce tail gas containing harmful components such as hydrogen chloride and chlorine. If these tail gases are discharged directly, they will cause serious harm to the environment and human health. For example, hydrogen chloride gas forms hydrochloric acid when it meets water, which is corrosive, and chlorine is a toxic gas. Therefore, an effective tail gas treatment device is needed to purify the tail gas.

[0003] When the absorption liquid is sprayed on the exhaust gas entering the tower body, the absorption liquid itself may contain some impurities, such as undissolved solid particles, dust, etc. During the spraying process, these impurities will gradually deposit on the inside of the connecting pipe, thereby interfering with the absorption liquid spraying work and further affecting the exhaust gas treatment work.

[0005] The beneficial effects of the present invention are as follows: 1. The present invention sets a connecting mechanism, and uses a water pump to extract the absorption liquid and move it in the connecting pipe, so that the absorption liquid drives the moving frame to move on the guide rod, and pulls the first spring at the same time, so that the moving frame drives the scraper to clean the inner side of the connecting pipe, thereby avoiding the absorption liquid from passing through the connecting pipe for a long time. The absorption liquid itself may contain some impurities, such as undissolved solid particles, dust, etc., and some components in the absorption liquid may remain in the connecting pipe. For example, when using alkaline solution to absorb sulfur dioxide, if the reaction is incomplete, the unreacted alkaline solution will remain in the connecting pipe. During the spraying process, these impurities will gradually deposit on the inner side of the connecting pipe, resulting in the phenomenon that the effective flow aperture of the connecting pipe becomes smaller.

[0006] 2. The present invention arranges a recovery component, and the absorption liquid that absorbs the acid gas enters the recovery shell through the top plate.

At the same time, the impurities mixed in the absorption liquid are collected by the collecting mechanism.

[0007] 3. The present invention sets a collecting mechanism, and drives the rotating frame through the output end of the motor to rotate on the top of the base. When the absorption liquid in the recovery shell rotates and impacts with the baffle, the baffle is subjected to the squeezing impact force of the absorption liquid, thereby driving the sliding rod to slide on the inner side of the connecting plate through the bent plate, so that the absorption liquid mixed with impurities enters the collection shell, and the recovery shell is driven to rotate continuously by the rotating frame, so as to collect the particulate impurities mixed in the absorption liquid. At the same time, by setting the bent plate to be curved, after the absorption liquid mixed with impurities enters the collection shell and flows out through the through hole, the impurities remaining in the collection shell can be blocked by the bent plate.

[0008] 4. The present invention provides a cleaning mechanism. When the exhaust gas treatment work is completed and the extraction pump stops working, the connecting frame is stretched by the reset of the third spring, and the cleaning rod is driven by the connecting frame to move toward the mesh of the filter plate, so that the cleaning rod drives the cleaning block to eject the impurities blocked in the mesh of the filter plate. At the same time, when the connecting frame is stretched by the reset of the third spring and continues to move toward the filter plate, the cleaning rod drives the arc plate through the connecting sleeve to contact and move the inner side of the mesh of the filter plate, thereby scraping off the impurities attached to the inner side of the mesh of the filter plate. At the same time, when the extrusion pressure between the arc plate and the inner side of the mesh of the filter plate is too large, the connecting sleeve is driven by the slider to slide in the groove. At the same time, the buffering work of the fourth spring is used to avoid the extrusion pressure between the arc plate and the inner wall of the mesh of the filter plate being too large, thereby causing friction damage to the inner side of the mesh of the filter plate, thereby causing the mesh of the filter plate to expand.

Example 3, using Figure 8-Figure 9 The following is a description of a chlorinated paraffin tail gas treatment device by absorption according to the present invention; like Figure 8-Figure 9 The present invention shows a chlorinated paraffin tail gas treatment device by absorption, based on the first embodiment; The filter component 5 includes a filter housing 51, the side of the filter housing 51 is fixedly connected to the inner side of the recovery housing 62, a filter plate 53 is fixedly connected to the side of the filter housing 51 close to the recovery housing 62, the inner side of the filter housing 51 is fixedly connected to the water suction port of the water pump 41, the inner side of the filter housing 51 is fixedly connected to the extraction pump 52, the side of the filter plate 53 is slidably connected to a connecting shaft 54, one end of the connecting shaft 54 ​​away from the filter plate 53 is fixedly connected to a connecting frame 55, one end of the connecting shaft 54 ​​away from the filter plate 53 is fixedly connected to the connecting frame 55, a third spring 56 is sleeved on the connecting shaft 54, one end of the third spring 56 is connected to the filter plate 53, and the filter plate 53 is fixedly connected to the filter plate 53. The filter plate 53 is fixedly connected, and the other end of the third spring 56 is fixedly connected to the connecting frame 55. The end of the connecting frame 55 close to the filter plate 53 is fixedly connected with a cleaning mechanism 57. By turning on the extraction pump 52, the absorption liquid that is coarsely filtered in the recovery housing 62 enters the filter housing 51 through the filter plate 53 for recovery. The pre-treated absorption liquid enters the main body 1 through the extraction work of the water pump 41, so that the exhaust gas entering the main body 1 is processed and absorbed. The extraction work of the extraction pump 52 causes the connecting frame 55 to move to the side away from the filter plate 53 through the connecting shaft 54. The cleaning mechanism 57 includes a cleaning rod 571, one end of the cleaning rod 571 away from the cleaning block 575 is fixedly connected to the connecting frame 55, a notch 572 is provided on the side of the cleaning rod 571, a slider 573 is slidably connected to the inner side of the notch 572, a sliding bar 574 is fixedly connected to the side of the sliding bar 573, and the side of the sliding bar 574 is slidably connected to the inner side of the cleaning rod 571, and the end of the sliding bar 574 away from the sliding bar 573 is fixedly connected to the cleaning block 575, and a fourth spring 576 is sleeved on the sliding bar 574, one end of the fourth spring 576 is fixedly connected to the cleaning rod 571, and the other end of the fourth spring 576 is fixedly connected to the cleaning block 575, and connecting sleeves 577 are fixedly connected to both sides of the sliding sleeve 573, and arc plates 578 are fixedly connected to both sides of the connecting sleeve 577; when the exhaust gas treatment work is completed, the extraction pump 52 stops working, the connecting frame 55 is stretched by the reset of the third spring 56, and the cleaning is driven by the connecting frame 55 The cleaning rod 571 moves toward the mesh of the filter plate 53, so that the cleaning rod 571 drives the cleaning block 575 to eject the impurities blocked in the mesh of the filter plate 53. At the same time, when the connecting frame 55 is stretched by the third spring 56 to continue to move toward the filter plate 53, the cleaning rod 571 drives the arc plate 578 through the connecting sleeve 577 to contact and move the inner side of the mesh of the filter plate 53, so as to scrape off the impurities attached to the inner side of the mesh of the filter plate 53. At the same time, when the extrusion pressure between the arc plate 578 and the inner side of the mesh of the filter plate 53 is too large, the connecting sleeve 577 is driven by the slider 573 to slide in the notch 572. At the same time, the fourth spring 576 works as a buffer to avoid the extrusion pressure between the arc plate 578 and the inner wall of the mesh of the filter plate 53 being too large, thereby causing friction damage to the inner side of the mesh of the filter plate 53, thereby causing the mesh of the filter plate 53 to expand. The specific workflow is as follows: The tower body of the absorption tower is the outer shell of the entire device, which provides a closed space for the absorption process. The absorption tower usually works in a gas-liquid countercurrent contact mode. In the tower, the gas enters from the air inlet 2, and the liquid absorbent enters and flows out from the spray component. This countercurrent operation mode allows the gas and liquid to fully contact. When the tail gas enters the main body 1 from the air inlet 2 and the absorption liquid sprays down from the top of the tower, the tail gas will form convection with the absorption liquid in the tower plate 7 area in the tower. There are many evenly distributed small holes on the tower plate. The gas rises through the small holes to form bubbles and contact with the alkali solution on the tower plate 7. As the gas flows upward, it contacts with fresher and fresher absorption liquid, because the absorption liquid near the top of the tower has just entered the tower and has the strongest absorption capacity, which can effectively absorb the solutes in the gas, and the liquid is constantly flowing downward. The solute in the absorbed gas gradually increases its solute concentration. This countercurrent contact method can make the absorption process efficiently carried out in the entire tower, maximize the absorption capacity of the absorbent, and thus achieve a higher absorption efficiency. The sprayed absorption liquid enters the recovery component 6, and after being processed, enters the filter component 5 for recycling. After absorption and reaction by the absorption liquid, the purified gas continues to rise, passes through the demisting layer 8, and after the gas-liquid contact reaction, a large amount of alkali liquid droplets will be entrained in the gas. The main function of the demisting layer 8 is to intercept these droplets to prevent them from being discharged from the absorption tower along with the purified gas and discharged from the discharge port 3 at the top of the absorption tower. A gas detection device is usually set at the discharge port 3 to monitor whether the acid gas concentration in the exhaust gas meets the emission standards; By turning on the water pump 41, the absorption liquid in the filter element 5 is pumped into the connecting mechanism 42 through the water pump 41. At the same time, through the extraction work of the water pump 41, the absorption liquid is sprayed inside the main body 1 through the spraying mechanism 43. The absorption liquid forms fine droplets through the spraying mechanism and is evenly sprayed on the cross section of the entire tower. This is like a "lye rain", which makes the tail gas have sufficient opportunities to contact with the absorption liquid during the rising process, so as to treat the tail gas entering the inside of the main body 1; The absorption liquid is pumped by the water pump 41 and moved in the connecting pipe 421, so that the absorption liquid drives the moving frame 425 to move on the guide rod 423, and at the same time pulls the first spring 427, so that the moving frame 425 drives the scraper 426 to clean the inner side of the connecting pipe 421, thereby preventing the absorption liquid from passing through the connecting pipe 421 for a long time. The absorption liquid itself may contain some impurities, such as undissolved solid particles, dust, etc., and some components in the absorption liquid may remain in the connecting pipe, such as using alkaline solution for absorption. When sulfur dioxide is sprayed, if the reaction is incomplete, the unreacted alkali solution will remain in the connecting pipe. During the spraying process, these impurities will gradually deposit on the inner side of the connecting pipe 421, thereby causing the effective flow aperture of the connecting pipe 421 to become smaller. At the same time, when the water pump 41 stops working, the moving frame 425 is driven by the stretching and resetting of the first spring 427, so that the moving frame 425 drives the scraper 426 to perform secondary cleaning and scraping work on the inner wall of the connecting pipe 421, thereby preventing these substances from adhering to the inner side of the connecting pipe and affecting the normal operation of the pipeline; The absorption liquid that has absorbed the acidic gas enters the recovery shell 62 through the top plate 63. By turning on the motor 64, the output end of the motor 64 drives the rotating frame 65 to rotate inside the recovery shell 62. The rotating frame 65 stirs and impacts the absorption liquid mixed with impurities that enters the recovery shell 62, and the collection mechanism 66 collects the impurities mixed in the absorption liquid. The output end of the motor 64 drives the rotating frame 65 to rotate on the top of the base 61. When the absorption liquid in the recovery shell 62 is rotated and impacted with the baffle 667, the baffle 667 is squeezed and impacted by the absorption liquid, so that the sliding rod 664 is driven by the curved plate 665 to slide on the inner side of the connecting plate 663, so that the absorption liquid mixed with impurities enters the collection shell 661, and the recovery shell 62 is driven by the rotating frame 65 to rotate continuously, so as to collect the particulate impurities mixed in the absorption liquid. The baffle 667 is arranged to be bent, and after the absorption liquid mixed with impurities enters the collection shell 661 and flows out through the through hole 662, the impurities remaining in the collection shell 661 can be blocked by the bent plate 665, thereby preventing the impurities in the collection shell 661 from being thrown out of the collection shell 661 when the baffle 667 is opened. At the same time, when the motor 64 stops rotating, the baffle 667 is stretched by the reset of the second spring 666 to block the side of the collection shell 661, thereby preventing the impurities in the collection shell 661 from sliding out. By turning on the extraction pump 52, the absorption liquid that has been roughly filtered in the recovery housing 62 enters the filter housing 51 through the filter plate 53 for recovery. The pre-treated absorption liquid enters the main body 1 through the extraction work of the water pump 41, so that the exhaust gas entering the main body 1 is processed and absorbed. The extraction work of the extraction pump 52 causes the connecting frame 55 to move to the side away from the filter plate 53 through the connecting shaft 54. When the exhaust gas treatment work is completed and the extraction pump 52 stops working, the connecting frame 55 is stretched by the reset of the third spring 56, and the cleaning rod 571 is driven by the connecting frame 55 to move toward the mesh of the filter plate 53, so that the cleaning rod 571 drives the cleaning block 575 to eject the impurities blocked in the mesh of the filter plate 53. At the same time, when the connecting frame 55 is stretched by the reset of the third spring 56 and continues to move toward the filter plate 53, the cleaning rod 571 drives the arc plate 578 through the connecting sleeve 577 to clean the mesh of the filter plate 53. The inner side of the filter plate 53 is contacted and moved, thereby scraping off impurities attached to the inner side of the mesh of the filter plate 53. At the same time, when the extrusion pressure between the arc plate 578 and the inner side of the mesh of the filter plate 53 is too large, the connecting sleeve 577 is driven by the slider 573 to slide in the groove 572. At the same time, the fourth spring 576 works as a buffer to avoid excessive extrusion pressure between the arc plate 578 and the inner wall of the mesh of the filter plate 53, which will cause friction damage to the inner side of the mesh of the filter plate 53, thereby causing the mesh of the filter plate 53 to expand.
