Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment equipment, in particular to a chemical tail gas treatment device. Background Art

[0002] A certain amount of tail gas is generated during chemical production, and the tail gas needs to be treated for harmful substances before it can be discharged into the external atmosphere. The tail gas generated during some chemical production will use a spray tower or adsorption box to adsorb harmful substances and odors in the tail gas;

[0003] When the harmful substances in the exhaust gas are adsorbed by the adsorption box, the adsorption medium in the adsorption box is mostly activated carbon. Because the surface of the activated carbon is covered with micropores and mesopores, a huge specific surface area is formed, which provides abundant space for the adsorption of harmful substances in the exhaust gas. These harmful substances include organic substances such as various hydrocarbons, alcohols, aldehydes, acids, ketones and amines, as well as inorganic substances such as ammonia and chlorine. Through the adsorption of activated carbon, these harmful substances can be effectively removed, thereby purifying the exhaust gas. At the same time, in order to ensure the adsorption efficiency and quality of the exhaust gas, some activated carbon adsorption boxes will be equipped with multiple storage tanks filled with activated carbon in the box. Storage boxes, thereby utilizing the airway diversion setting in the adsorption box, can make the exhaust gas pass through the activated carbon in these storage boxes. As the use time increases, the pollutants adsorbed by the activated carbon will gradually increase until its saturation capacity is reached. At this time, the adsorption effect of the activated carbon will be greatly reduced, and may even cause secondary pollution. Therefore, the activated carbon in the storage box needs to be replaced. However, when replacing the activated carbon in a storage box with a higher installation height, the activated carbon stored in the storage box has a certain weight and cannot be directly drawn out for discharge operation. Therefore, it brings inconvenience to the discharge of the activated carbon in the high storage box. Utility Model Content

[0029] like Figure 1-Figure 2 , Figure 7As shown, a plurality of sliders 15 are fixedly installed on the rear side of the discharge square tube 8, and the sliders 15 are slidably connected to the corresponding guide rails 7. The discharge square tube 8 is slidably connected between the two guide rails 7 through the plurality of sliders 15, and the use position of the discharge square tube 8 can be adjusted according to the activated carbon storage box 2 to be discharged. Stainless steel mesh plates are fixedly installed in the first fixed frame 4, the second fixed frame 5 and the movable frame 6. One side of the movable frame 6 is also inserted between the bottom of the activated carbon storage box 2 and the second fixed frame 5. A push-pull rod 25 is fixedly installed on one side of the upper end of the movable frame 6. The push-pull rod 25 can be used to realize the pulling and moving of the movable frame 6 in the activated carbon storage box 2, thereby facilitating the discharge of the activated carbon in the activated carbon storage box 2 through the channel opened after the movable frame 6 moves.

[0030] like Figure 1-Figure 6 As shown, a plurality of positioning protrusions 24 are fixedly installed on both sides of the blanking square tube 8 between the two sealing covers 10. The plurality of positioning protrusions 24 on both sides of the blanking square tube 8 are arranged so that the crank 14 can cooperate with the groove on one side to realize the positioning of the rotation angle.

[0031] It should be noted that the utility model is a chemical tail gas treatment device. When the activated carbon in the activated carbon storage box 2 arranged at the corresponding position in the adsorption box 1 needs to be replaced, the unloading square tube 8 can be directly pushed manually, so that the unloading square tube 8 can slide horizontally between the two guide seats 17 with the help of multiple sliders 15 on the rear side, and then the use position of the unloading square tube 8 can be quickly adjusted. After the corresponding through groove 9 in the unloading square tube 8 moves to the front side position of the activated carbon storage box 2 where the activated carbon needs to be replaced, the unloading square tube 8 can be stopped from being pushed, and then, through the front side of the activated carbon storage box 2 The handle on the side is used to pull the activated carbon storage box 2 out of the adsorption box 1. At this time, since the upper end surface and the lower end surface of the fixed skirt 3 are both protruding from the upper end surface and the lower end surface of the activated carbon storage box 2, the fixed skirt 3 will squeeze the corresponding guide seat 17 on the rear side of the first sealing plate 11. Therefore, the first sealing plate 11 will move on the multiple connecting bolts 19 through the multiple countersunk holes 18 and compress the compression spring 20. When the fixed skirt 3 passes through the guide seat 17, the first sealing plate 11 is reset with the help of the force of the compression spring 20 stretching and rebounding, and one end of the first sealing plate 11 will contact the active carbon storage box 2. The upper end surface or the lower end surface of the activated carbon storage box 2 is moved, and then the activated carbon storage box 2 is continued to be pulled outward, and the movable frame 6 is placed in the discharge square tube 8. At this time, the push-pull rod 25 can be manually pulled toward the operator, so that the push-pull rod 25 drives the movable frame 6 to move toward the operator, so that a discharge channel appears at the bottom of the activated carbon storage box 2, and the activated carbon in the activated carbon storage box 2 can fall through the channel opened after the movable frame 6 is moved, and is guided through the discharge square tube 8 to fall into the collection container pre-placed below the discharge square tube 8. When the activated carbon storage box After the activated carbon in 2 is discharged, the movable frame 6 can be pushed back to its original position by the push-pull rod 25, and then the new activated carbon can be gradually poured into the activated carbon storage box 2, and then the activated carbon storage box 2 can be pushed into the adsorption box 1, and similarly, the fixed skirt 3 squeezes and moves the guide seat 17 corresponding to the front side of the first sealing plate 11 in turn, so that the first sealing plate 11 moves up, and then it is convenient for the fixed skirt 3 to pass through the through groove 9 to the front side of the adsorption box 1, and then, when the activated carbon storage box 2 is completely pushed into the adsorption box 1, the feeding square tube 8 can be removed;

[0032] When the activated carbon storage box 2 at the top of the front side of the adsorption box 1 needs to discharge the activated carbon, the through groove 9 needs to be closed to prevent the activated carbon from splashing out during discharge, which increases the workload of later cleaning. At this time, the operating handle 23 can be manually rotated, and the operating handle 23 drives the crank 14 to rotate on one side of the discharge square tube 8. Therefore, the crank 14 also pulls the corresponding connecting rod 13 through the two second fixed shafts 22 on one side, so that the other ends of the two connecting rods 13 pull the corresponding first fixed shaft 12 respectively, so that the two connecting rods 13 respectively pull the corresponding sealing cover 10 relative to each other, so that the two sealing covers 10 respectively move vertically relative to each other on the outside of the discharge square tube 8, and make the front and rear sides of the two discharge square tubes 8 fit on the opposite side of the first sealing plate 11, and the positioning groove on one side of the crank 14 is inserted into the corresponding positioning protrusion 24, so that the movement limit of the crank 14 can be completed, and then the two sets of sealing covers 10 and the first sealing plate 11 are used to close the through groove 9.
