Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a waste gas treatment adsorption tower with cyclically moving adsorption fillers. Background Art

[0002] Adsorption is an important method for waste gas treatment, with simple equipment, low energy consumption and simple operation. The utilization rate of the adsorbent in the adsorption method is a very critical factor. In traditional adsorption towers, adsorbents are generally stacked into adsorption beds, and gas paths are set in the adsorption beds to avoid excessive resistance to gas circulation. This type of adsorption tower needs to find a balance between gas circulation resistance and adsorbent utilization, and cannot fully improve the utilization rate of the adsorbent. Moreover, most of the current adsorbent beds are fixed beds. After long-term operation, dead zones, channeling and other adverse conditions are prone to occur, resulting in a decrease in the adsorption treatment effect. The currently feasible method is to reversely flush the adsorbent bed after shutdown to loosen it and re-stack it evenly. Summary of the invention

The specific shape of the support disc frame 19 is not limited, as long as it can support the adsorption plate, and the area of ​​the support disc frame 19 is not larger than the area of ​​the corresponding adsorption plate.

[0052] The horizontal adsorption layer of the present invention can move from top to bottom along the positioning column 4 and several track columns 8, and at the same time, several adsorption disks can also rotate around the positioning column 4. Specifically, the segments 20 are interlocked to form a circular connecting ring 15, and the connecting ring 15 is sleeved on the outside of the positioning column 4, and the protruding strip 22 of the connecting ring 15 is inserted into the corresponding first slide 5, so that the connecting ring 15 can only move up and down, and cannot rotate left and right. The adsorption disk is fixed on the corresponding support disk rack 19 and can move with the support disk rack 19. The connecting rod 1 23 moves along the second slide 13, and the connecting rod 2 24 moves along the third slide 14. It only needs to control the moving speed of the connecting rod 1 23 and the connecting rod 2 24, so that the connecting line of the connecting rod 1 23 and the connecting rod 2 24 can be along the radial direction of the tower body 1, and the supporting disk rack 19 drives the adsorption disk to rotate around the positioning column 4. The rotation mechanism of the other several adsorption disks is as above.

The driving device 28 is fixed on the side of the first slider 9.

[0057] The outer surfaces of the top rail 29, the bottom rail 30 and the vertical rail 16 are all provided with slideways corresponding to the first slideway, so that the second slider can cyclically move along the positioning column, the bottom rail 30, the vertical rail 16 and the top rail 29 in sequence;

[0058] The top track 29 is located above the upper moving loop, the bottom track 30 is located below the lower moving loop, the vertical track 16 is located on the inner wall of the tower body, and the circulating track does not affect the movement of the adsorption disks in the main adsorption area and the auxiliary adsorption area.

[0059] The top and bottom of the positioning column are respectively connected to the inner wall of the tower body by at least one connecting rod to fix the positioning column; the top track can be connected to the top of the tower body by the connecting rod, the bottom track can be connected to the bottom of the tower body by the connecting rod, and the vertical track can be connected to the side wall of the tower body by the connecting rod to fix the top track, the bottom track and the vertical track.

[0060] When in use, when the horizontal adsorption layer descends to a position close to the bottom of the track column 8, each adsorption plate rotates to a position corresponding to the middle of a segment 1 20 and a segment 2 21, and each segment 1 20 of the connecting ring 15 is disconnected, and each segment 21 of the connecting ring 2 17 is disconnected, so that a segment 1 20, the adsorption plate and the segment 2 21 become a group of components, and the component can rotate with the block 26 of the first slider 9 around the rotation axis 27. The component starts from a horizontal state and rotates downward, while the horizontal adsorption layer continues to descend. The driving part corresponding to the horizontal adsorption layer continues to move along the bottom track 30, and then moves to the top of the positioning column along the vertical track 16 and the top track 29, and the moving speed of the driving part is controlled so that the corresponding driving part is equivalent to the vertical height of the component, so that when the driving part moves to the top of the positioning column again, it is convenient to receive the connecting ring 1 of the corresponding component. When the first slider 9 descends to the bottom of the track column 8 (i.e., the connection between the bottom of the track groove 1 11 and the bottom of the track groove 2 12), the above-mentioned component rotates to a vertical downward state. Then the first slider 9 moves up along the track groove 12, and the above-mentioned component rotates upward, so that the component and the track column 8 form a certain angle, so that the adsorption plate is tilted and can contact the rising airflow of the auxiliary adsorption area 3 for adsorption.

[0061] When the first slider 9 moves up to the top of the track column 8 (i.e., the connection between the top of the track groove 12 and the top of the track groove 11), the above-mentioned components rotate to a vertical upward state. Then the first slider 9 moves down along the track groove 11, and the above-mentioned components rotate downward to a horizontal state, so that the adsorption plate is also horizontal. At this time, the corresponding driving part has also completed a circle of circular movement and moved to the bottom of the segment 1, ready to receive the corresponding connecting ring 1. In this rotation process, the components on each first slider 9 gradually approach each other, and the segment 1 20 of each component gradually approaches the positioning column 4 until the raised strip 22 of the segment 1 20 is inserted into the corresponding first slide 5. When the two ends of each segment 1 20 contact each other, each segment 1 20 is buckled together to form a connecting ring 15, and the second slide 13 forms a complete circle. At this time, the two ends of each segment 21 also contact each other, and each segment 21 is buckled together to form a connecting ring 2 17, and the third slide 14 forms a complete circle, that is, each component is reassembled into a complete horizontal adsorption layer. The connecting rod 1 23 and the connecting rod 24 can drive the corresponding adsorption disk and the supporting disk frame 19 to move along the second slide 13 and the third slide 14, and the horizontal adsorption layer passes through the corresponding first sliders 9 and descends along the track groove 1 11 again. At this point, the cyclic movement of the adsorption disk between the main adsorption area 2 and the auxiliary adsorption area 3 is completed.

[0062] The present invention divides the interior of the tower body 1 into a main adsorption area 2 and a secondary adsorption area 3. The adsorption disk in the main adsorption area 2 is horizontally arranged and can rotate, and the adsorption disk in the secondary adsorption area 3 is inclined and can rotate with the track column 8. At the same time, the adsorption disk can circulate in the main adsorption area 2 and the secondary adsorption area 3, thereby improving the accumulation and distribution state of the adsorbent in the adsorption disk and improving the utilization rate of the adsorbent.

[0063] In the main adsorption area 2, the exhaust gas flows upward, passing through each horizontal adsorption layer. Each track column 8 moves along the upper moving ring 6 and the lower moving ring 7, which can drive each horizontal adsorption layer to rotate with the positioning column 4 as the center, so that the exhaust gas is fully in contact with the adsorbent. At the same time, in order to adjust the relative positions of the upper and lower horizontal adsorption layers, the rotation speed of each horizontal adsorption layer on the corresponding second slide 13 and third slide 14 can be controlled separately. For example, all the adsorption disks of the upper horizontal adsorption layer rotate around the positioning column 4 at one speed, and all the adsorption disks of the lower horizontal adsorption layer rotate around the positioning column 4 at another speed, so that the gap between two adjacent adsorption disks of the upper layer corresponds to an adsorption disk of the lower layer, so that the rising airflow can pass through the adsorption disk, and then pass between the two adsorption disks of the upper layer, so that the resistance to the rising airflow is moderate, and at the same time it can fully contact the adsorbent.

[0064] The airflow in the main adsorption zone 2 is driven by the rotating horizontal adsorption layer to form an oblique upward airflow. The airflow enters the outer auxiliary adsorption zone 3 from the main adsorption zone 2. The adsorption disk of the auxiliary adsorption zone 3 is tilted, and the tilt angle can be adjusted by the driving device 28 and the rotating shaft 27 of the first slider 9. According to the airflow direction of the auxiliary adsorption zone 3, the tilt angle of the adsorption disk can be adjusted in real time so that the airflow contacts the adsorption disk in countercurrent. Through the dual adsorption action of the main adsorption zone 2 and the auxiliary adsorption zone 3, the exhaust gas flow in the tower body 1 is disturbed, so that the exhaust gas and the adsorbent are fully contacted in multiple dimensions, thereby improving the utilization rate and adsorption effect of the adsorbent. The adsorption disk is always in a state of rotation and / or flipping, which prevents the material in the adsorption disk from being too densely piled up, is conducive to flipping and loosening the adsorbent, improving the contact state between the exhaust gas and the adsorbent, and improving the adsorption efficiency.

[0065] According to the actual exhaust gas treatment volume and the content of pollutants in the exhaust gas, the number of horizontal adsorption layers, the height of the track column, the number of adsorption discs and the filling amount and other parameters are reasonably designed.
