Description

Technical Field

[0001] This utility model relates to the field of packed tower technology, and in particular to a high-efficiency and energy-saving packed tower. Background Technology

[0002] A packed tower is a type of tower equipment. The tower is filled with packing material of appropriate height to increase the contact surface between two fluids. For example, in gas absorption, the liquid enters from the top of the tower through a distributor and descends along the surface of the packing. The gas, on the other hand, flows counter-currently upwards from the bottom of the tower through the pores of the packing, interacting closely with the liquid. It has a relatively simple structure and is easy to maintain. It is widely used in gas absorption, distillation, extraction, and other operations.

[0003] Because traditional packed towers use a single spray device and the height of the spray device is not adjustable, it is impossible to make the liquid evenly distributed and fully wet the packing, resulting in insufficient utilization of the mass transfer area and reduced separation efficiency. In view of the above reasons, this application proposes a high-efficiency and energy-saving packed tower. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a high-efficiency and energy-saving packed tower.

[0006] The spray structure includes an inlet pipe and two threaded rods for transmission. One of the threaded rods has a servo motor for driving on one side. A horizontal plate for mounting is provided above the two threaded rods. Two vertical rods for connection are provided at the bottom of the horizontal plate. An annular tube is fixed at the bottom end of the two vertical rods. A liquid guide tube is provided in the center of the annular tube.

[0011] Optionally, one of the threaded rods is externally fixed with a bevel gear one, and the output end of the servo motor is fixedly fixed with a bevel gear two, the bevel gear two and the bevel gear one meshing and transmitting power.

[0012] Optionally, the structured packing is a perforated metal plate corrugated packing, and the surface of the structured packing is provided with staggered micro-protrusions.

This allows the liquid to fully wet the packing material, ensuring sufficient mass transfer area utilization and improving separation efficiency.

[0015] 2. By setting up structured packing and micro-protrusions, this utility model can increase the turbulence intensity at the gas-liquid contact interface, extend the effective mass transfer time, and reduce the packing layer height under the same separation effect, thereby achieving the purpose of reducing energy consumption.

[0037] Example

[0038] like Figure 1-5 As shown, the present invention proposes a high-efficiency and energy-saving packed tower, including a tower body 1, an inlet pipe 2 for introducing the gas to be treated on one side of the tower body 1, an outlet pipe 3 for discharging the gas at the top of the tower body 1, a liquid outlet pipe 4 at the bottom of the tower body 1, a packing frame 5 for support and fixation inside the tower body 1, and large-size bulk packing 6, structured packing 7 and small-size bulk packing 8 arranged sequentially on the top of the packing frame 5, and a spray structure 10 for promoting full contact between gas and liquid inside the tower body 1.

[0039] The spray structure 10 includes an inlet pipe 101 and two threaded rods 102 for transmission. A servo motor 103 for driving is provided on one side of one of the threaded rods 102. A horizontal plate 108 for mounting is provided above the two threaded rods 102. Both threaded rods 102 are movably connected to the top of the tower body 1. Pulleys 106 are fixedly mounted on the outside of each of the two threaded rods 102, and the same belt is fitted onto both pulleys 106. A bevel gear 105 is fixedly mounted on the outside of one of the threaded rods 102, and a bevel gear 104 is fixedly mounted on the output end of the servo motor 103. The bevel gear 104 and bevel gear 105 mesh and transmit power. Internal threaded sleeves 107 are movably fitted on the outside of each of the two threaded rods 102. The tops of the two internal threaded sleeves 107 are fixedly connected to the bottom of the horizontal plate 108. Two vertical rods 10 are provided at the bottom of the horizontal plate 108 for connection. 9. Vertical rods 109 penetrate the top of tower body 1 and are movably connected to the inner wall of the top of tower body 1. Annular pipes 1010 are fixedly installed at the bottom of the two vertical rods 109. A liquid guide pipe 1012 is provided in the center of the annular pipe 1010. A liquid guide hose 1015 is fixedly installed at the top of the liquid guide pipe 1012. The other end of the liquid guide hose 1015 is fixedly connected to one end of the liquid inlet pipe 101. Multiple water distribution pipes 1011 are equidistantly arrayed outside the liquid guide pipe 1012. The ends of the multiple water distribution pipes 1011 away from the liquid guide pipe 1012 are all fixedly connected to the annular pipe 1010. Multiple fan-shaped nozzles 1014 are provided below the annular pipe 1010. A spiral nozzle 1013 is provided below the liquid guide pipe 1012. The spiral nozzle 1013 realizes uniform liquid distribution in the central area. The fan-shaped nozzles 1014 can enhance the liquid distribution near the tower wall and solve the problem of the central dry area caused by the "wall flow effect".

[0040] The structured packing 7 is a metal perforated plate corrugated packing. The surface of the structured packing 7 is provided with staggered micro-protrusions 9, which can increase the turbulence intensity of the gas-liquid contact interface, prolong the effective mass transfer time, and reduce the packing layer height under the same separation effect, thereby achieving the purpose of reducing energy consumption.

[0041] In this embodiment, the air inlet pipe 2 is used to introduce gas. During use, the spray height is adjusted by considering various factors. The servo motor 103 is started, which drives the second bevel gear 104. The second bevel gear 104 drives the threaded rod 102 through the first bevel gear 105. The threaded rod 102 then drives the other pulley 106 through one of the pulleys 106, so that the two threaded rods 102 rotate in the same direction at the same time. The two threaded rods 102 then drive the inner threaded sleeve 107, which in turn drives the top horizontal plate 108. The horizontal plate 108 then drives the vertical rod 109, which in turn drives the annular tube 1010. The annular tube 1010 then drives the liquid guide tube 1012, thereby adjusting the spiral nozzle 1013 and the fan-shaped nozzle 1014. After the adjustment is completed, the servo motor 103 is turned off and the liquid is introduced into the liquid inlet pipe 101. Finally, the liquid is sprayed out from multiple nozzles. Then, gas is introduced through the air inlet pipe 2 for separation.

[0042] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
