[0028] Each tray 2 is equipped with an automatic cleaning device and a pneumatic slag discharge device. Each tray 2 has a tray slag discharge through hole 21 at a local location. A baffle plate 22 is integrally installed on the tray 2 at the upper end of the tray slag discharge through hole 21. The automatic cleaning device dynamically cleans the upper and lower surfaces of the tray 2. The pneumatic slag discharge device is located near the tray slag discharge through hole 21 and discharges waste residue from the tray slag discharge through hole 21.

Each tray 2 has at least three vertical through-holes, and these through-holes of varying diameters are arranged in a uniform cross-flow pattern. This ensures close and sufficient contact between the gas and liquid phases, providing a sufficiently large and continuously renewing interphase contact surface for the mass transfer process, thereby reducing mass transfer resistance.

[0030] Each cylindrical tube 1 is provided with an observation window 13 near each layer of tower plate 2.

[0031] To make the structural design of this utility model more reasonable, as a preferred embodiment, the automatic cleaning device includes a motor 3, a reduction gear 4, a base 5, a hollow transmission shaft 6, a hollow stirring shaft 7, and a cleaning nozzle.

The first connecting flange 61 and the second connecting flange 72 are connected and fixed by bolts.

[0034] The cleaning nozzle includes a first branch pipe 8 and a second branch pipe 9, which are staggered at 90°. A tray is provided between the first branch pipe 8 and the second branch pipe 9. The first branch pipe 8 is provided with a plurality of first cleaning liquid injection holes facing the upper plate surface of the tray 2, and the second branch pipe 9 is provided with a plurality of second cleaning liquid injection holes facing the upper plate surface of the tray 2.

[0035] Preferably, in this embodiment, a tray mounting position 71 is provided between the first branch pipe 8 and the second branch pipe 9, and the tray 2 is sleeved on the tray mounting position 71.

[0036] The angle between the water column ejected from the first cleaning liquid injection through-hole and the upper plate surface of the tower plate 2 is 60°, and the water column ejected from the first cleaning liquid injection through-hole pushes the waste residue to the slag discharge through-hole 21 of the tower plate.

[0037] The pneumatic slag discharge device includes a pneumatic drive device 10 and a rotating shaft 11. A slag discharge channel 111 is provided on the rotating shaft 11. The pneumatic drive device 10 drives the rotating shaft 11 to rotate. When the rotating shaft 11 rotates 90°, the slag discharge channel 111 is aligned with the slag discharge through hole 21 of the tower plate.

[0038] The rotating shaft 11 is positioned on the lower surface of the adjacent tower plate 2, and the rotating shaft 11 is positioned close to the lower port of the slag discharge through hole 21.

[0039] A positioning sleeve 23 is integrally provided in the middle of the tower plate 2, and the hollow stirring shaft 7 is disposed through the positioning sleeve 23; the side of the tower plate 2 is locally connected and fixed to the inner wall of the cylindrical body 1 by bolts.

[0040] The outer end of the rotating shaft 11 is connected to the pneumatic drive device 10, and the inner end of the rotating shaft 11 is connected to the positioning sleeve 23 by a pin or bolt. Preferably, the pneumatic drive device 10 is located on the outside of the cylindrical body 1, and the pneumatic drive device 10 includes a pneumatic motor.

[0041] The lower end of the cylindrical body 1 is provided with a sewage outlet 12. An arc-shaped guide plate 13 is provided at the inner port of the sewage outlet 12. The edge of the arc-shaped guide plate 13 is fixedly connected to the inner wall of the cylindrical body 1. Waste residue is slid down to the inner port of the sewage outlet 12 through the arc-shaped guide plate 13.

[0042] Preferably, in this embodiment, the hollow stirring shaft 7 is provided with 9 layers of tower plates 2 from top to bottom.

[0043] In practical applications, the cylindrical body 1 is made of stainless steel, which has excellent corrosion resistance, temperature resistance, and mechanical properties, providing a contact space for gas-liquid or liquid-liquid.

[0044] Multiple vertical through holes of different sizes are opened on each tray 2. The gas and liquid phases are uniformly cross-flowed on each tray. The gas and liquid phases must maintain close and sufficient contact to provide a sufficiently large and constantly renewed interphase contact surface for the mass transfer process, so as to reduce the mass transfer resistance. The gas and liquid phases in the cylindrical shell flow in countercurrent to provide a larger mass transfer driving force.

[0045] The installation method of tray 2 and its fixing components must consider structural strength, sealing performance, maintainability, and adaptability to thermal expansion. The tray and the cylindrical shell are connected by tray fixing components. The edges of the tray rest on the tray fixing components on the inner wall of the tower body, and are secured at the top with bolts. The tray fixing components are connected and secured to the tower body with bolts or set screws. Corrosion-resistant gaskets are installed between the tray fixing components and the cylindrical shell to reduce edge clearance. This fixing method is removable, facilitating cleaning or replacement.

[0046] The motor shaft of motor 3 is directly inserted into the hollow shaft of the reducer. The reducer uses helical gears. The core advantage of using helical gears (helical cylindrical gears) lies in the optimized transmission performance through the inclined design of the gear teeth, which is superior to spur gears, especially in terms of load-bearing capacity, transmission smoothness, and applicable scenarios. It is fixed by keyways or shrink sleeves, eliminating intermediate transmission components; suitable for small equipment with limited space or compact servo systems.

[0047] Automatic cleaning: Powered by motor 3, the hollow stirring shaft 7 and hollow drive shaft 6 rotate synchronously. The hollow drive shaft 6, as the core transmission component, transmits power to the rotary cleaning device, causing it to rotate. The hollow drive shaft 6 serves both transmission and media conveying functions, allowing high-pressure cleaning fluid to pass through it. Simultaneously, cleaning water is transported to the cleaning nozzles through the internal channels of the hollow drive shaft 6. The cleaning nozzles include a first branch pipe 8 and a second branch pipe 9, which are installed along the axial direction of the hollow drive shaft 6 corresponding to the positions of each tray layer. The openings of the first branch pipe 8 and the second branch pipe 9 face the upper and lower tray surfaces of the tray, respectively, and adjacent branch pipes are staggered at 90° angles. During the rotation of the hollow drive shaft 6, the high-pressure cleaning fluid is directionally sprayed through the cleaning fluid injection holes of the first branch pipe 8 and the second branch pipe 9, creating an all-around scouring effect on the tray surface. The rotation of the rotary cleaning device enables dynamic cleaning of each tray layer, achieving efficient cleaning.

[0048] High-efficiency slag discharge: The hollow stirring shaft 7 is set close to the lower end of the slag discharge through hole 21 of the tower plate to prevent the liquid phase from falling from the slag discharge through hole 21 of the tower plate over a large area; during sewage discharge, the pneumatic drive device 10 distributed on the side of the cylindrical body 1 drives the rotating shaft 11 to rotate 90° so that the slag discharge channel 111 is aligned with the slag discharge through hole 21 of the tower plate, which makes it easy for dirt to fall from the upper tower plate to the lower layer. After being cleaned layer by layer, it is discharged from the sewage outlet 11 at the lower end of the cylindrical body 1, which is not easy to block.

[0049] This utility model has a reasonable structural design, which integrates the synergistic effects of power transmission, media conveying and mechanical cleaning. Through the "one shaft, two uses" of the hollow drive shaft (which transmits torque and conveys cleaning water), the structure is simple and efficient in cleaning and maintaining the key components of the through-plate tower, ensuring the stable operation of the tower equipment, and making the cleaning work highly efficient, convenient to maintain and stable.

[0050] In addition, the pneumatic drive unit rotates the rotating shaft to achieve actions such as residue agitation, opening and closing of slag discharge holes, and waste liquid pushing, which avoids residue clogging of the tower plates or pipes, ensures fluid flow and mass transfer efficiency in the tower, and completely solves the problem of clogging of traditional tower plate channels. This makes the tower less prone to clogging, easier to discharge slag, and allows for continuous operation without the need for shutdown for slag cleaning, making it suitable for continuous industrial production. The 9-layer tower plate enables the step-by-step separation and cleaning of waste residue, with good graded treatment effect, high purification efficiency, and good practicality.

[0051] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
