[0021] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment one:

[0023] Reference Figure 1-4 , a foldable tower tray assembly for storage, including a connecting plate 1, a first tower tray 4 is provided on one side of the connecting plate 1, a second tower tray 5 is provided on the side of the connecting plate 1 away from the first tower tray 4, a partition 2 is provided on one side of the first tower tray 4, three triangular brackets 15 are provided at the bottom of the first tower tray 4, a liquid receiving tray 3 is provided on the surface of the second tower tray 5, and four hinges 9 are provided at the bottom of the first tower tray 4, two limiting frames 10 are provided on the bottom surface of the connecting plate 1, two supporting plates 11 are provided in the middle of the two limiting frames 10, and the bottom surfaces of the two supporting plates 11 are provided with vertical plates 12, and two damping blocks 14 are provided on the surfaces of the two limiting frames 10, and two card blocks 13 are provided on both sides of the two support plates 11, and a fixing plate 6 is provided at the bottom of the two limiting frames 10, and two card slots 7 are provided on the surface of the fixing plate 6, and a fixing bolt 8 is provided at the bottom of the fixing plate 6, and the four hinges 9 are set in parallel at both ends of the connecting plate 1 as a group, and the hinges 9 are all installed by fixing bolts 8 On the connecting plate 1, the first tower plate 4 and the second tower plate 5, the connecting plate 1 and the first tower plate 4 are connected by a hinge 9, and the connecting plate 1 and the second tower plate 5 are connected by a hinge 9, the partition 2 is installed on the first tower plate 4 through a triangular bracket 15, and the liquid receiving plate 3 is installed on the top surface of the second tower plate 5, two limit frames 10 are set in the middle of the four hinges 9, and the limit frames 10 are all installed on the connecting plate 1, the two damping blocks 14 on the surfaces of the two limit frames 10 are both set on the side close to the connecting plate 1, and the positions of the damping blocks 14 on the surfaces of the two limit frames 10 correspond one to one, the two support plates 11 are set in the middle of the connecting plate 1 and the fixed plate 6, the blocks 13 on the surfaces of the two support plates 11 are both set on the side close to the damping block 14, and the vertical plate 12 is set at the end away from the block 13, the fixed plate 6 is installed on the limit frame 10 by two fixing bolts 8, and the card grooves 7 are evenly set at one end close to the two vertical plates 12.

[0024] The first tower plate 4 and the second tower plate 5 are connected to the connecting plate 1 by four hinges 9. The hinges 9 are evenly set up at both ends of the connecting plate 1 in two parallel groups, and one end of the hinge 9 is installed on the connecting plate 1, and the other end is installed on the first tower plate 4 and the second tower plate 5 respectively. The hinge 9 is installed on the connecting plate 1, the first tower plate 4 and the second tower plate 5 by fixing bolts 8. Since the first tower plate 4 and the second tower plate 5 are connected to the connecting plate 1 by hinges 9, the first tower plate 4 and the second tower plate 5 can be rotated when the installation is completed. The connecting plate 1 is set up in the middle of the first tower plate 4 and the second tower plate 5. Two support plates 11 are provided in the middle of the two limit frames 10 on the bottom surface of the connecting plate 1. The limit frames 10 are installed on the connecting plate 1, usually with fixing bolts 8. The two support plates 11 are connected or directly welded to the connecting plate 1, and the two support plates 11 are fixed to the connecting plate 1 with a fixing plate 6. The fixing plate 6 is installed on the two limit frames 10 by four fixing bolts 8. In this way, when the fixing plate 6 is installed, the support plate 11 is stuck in the middle of the fixing plate 6 and the connecting plate 1. During installation, the vertical plate 12 on the surface of the support plate 11 is pulled. The vertical plate 12 acts as a handle, and the two support plates 11 are pulled from the bottom of the connecting plate 1 to both sides through the vertical plate 12. Since two damping blocks 14 are provided on the surface of the two limit frames 10, and the damping blocks 14 are both set on the side close to the support plate 11, the blocking blocks 13 on both sides of the two support plates 11 are set in the middle of the four damping blocks 14. In this way, when the support plate 11 moves to a certain extent on both sides, the two support plates The block 13 of 11 will be blocked by the damping block 14 on the surface of the limit frame 10 to prevent the support plate 11 from being pulled excessively and causing the support plate 11 to fall off. When the support plate 11 is pulled out, one end of the two support plates 11 is installed on the first tower plate 4 and the second tower plate 5 by the fixing bolts 8, so that the support plate 11 supports the first tower plate 4 and the second tower plate 5, preventing the first tower plate 4 and the second tower plate 5 from being impacted and rotating during use, causing the tower plates to deviate. When the tower plates are in use, the liquid falls from the downcomer of the top tower plate onto the liquid receiving plate 3 of the second tower plate 5. The liquid receiving plate 3 receives the impact of the liquid and flows the liquid horizontally through the second tower plate 5, the connecting plate 1 and the first tower plate 4, and is blocked by the partition 2 of the first tower plate 4. The partition 2 plays the role of overflow weir and downcomer. The partition 2 is installed on the first tower tray 4 through three triangular brackets 15. When the triangular bracket 15 is installed, one end of the triangular bracket 15 is against the partition 2, and the other end is against the first tower tray 4, and the triangular bracket 15 is fixed to the partition 2 and the first tower tray 4 with fixing bolts 8. Since float valves are provided in the valve holes on the surfaces of the first tower tray 4 and the second tower tray 5, the gas pushes the valve plate of the float valve upward through the valve holes of the first tower tray 4 and the second tower tray 5, and the rising air flow enters the liquid layer in the horizontal direction through the gap between the valve plate and the tower plates of the first tower tray 4 and the second tower tray 5, thereby increasing the gas-liquid contact time. The opening of the float valve changes with the gas load. When the gas volume is low, the opening is small, and the gas can still pass through the gap at a sufficient gas velocity to avoid excessive leakage. When the gas volume is high, the valve plate automatically floats and the opening increases.To prevent the gas speed from being too high, it is ejected horizontally. When passing through the liquid layer, the gas-liquid two-phase form a foam state to carry out heat and mass transfer processes. The liquid after the gas-liquid mixture is completed falls into the liquid receiving tray 3 of the bottom tower tray through the partition 2. After the above process is repeated, when it is stored, the fixing bolts 8 on the surfaces of the two support plates 11 can be removed, and the vertical plates 12 on the surfaces of the two support plates 11 can be pushed to retract the two support plates 11 into the bottom of the connecting plate 1, and the vertical plates 12 on the surface of the support plates 11 are clamped into the clamping grooves 7 of the fixing plate 6, so that the two support plates 11 are tightly retracted between the connecting plate 1 and the fixing plate 6. Since the first tower tray 4 and the second tower tray 5 are connected to the connecting plate 1 by hinges 9, when the support plate 11 is retracted to the bottom of the connecting plate 1, the first tower tray 4 and the second tower tray 5 lose their supporting parts. At this time, the first tower tray 4 and the second tower tray 5 can be rotated to rotate downward, and the partition 2 on the surface of the first tower tray 4 is against the bottom surface of the second tower tray 5 to complete the storage. , Specific embodiment two:

[0026] Reference Figure 1-4 A foldable tower tray assembly for storage, further based on the basic structure in the specific embodiment 1, can be provided with a card slot 7 on the bottom surface of the second tower tray 5, the position of the card slot 7 is consistent with the position where the partition 2 is against the bottom surface of the second tower tray 5 when rotating for storage, so that the bottom end of the partition 2 of the first tower tray 4 is inserted into the card slot 7 of the second tower tray 5 when stored, so that the first tower tray 4 and the second tower tray 5 are fixed together when stored.

[0027] In summary:

[0028] When the folding plate 1 is folded, the first and second tower trays 4 and 5 are connected to each other through the hinge 9. When the folding plate 1 is folded, the first and second tower trays 4 and 5 are connected to each other through the hinge 9. When the folding plate 1 is folded, the first and second tower trays 4 and 5 are connected to each other through the hinge 9. When the folding plate 1 is folded, the first and second tower trays 4 and 5 are connected to each other through the hinge 9. When the folding plate 1 is folded, the first and second tower trays 4 and 5 are connected to each other through the hinge 9.
