Description

Technical Field

[0001] The utility model relates to the technical field of ship flue gas decarbonization systems, and in particular to a cooling device on a shaft of a supergravity machine used for ship exhaust gas decarbonization. Background Art

[0002] The mass transfer separation technology used by the ultra-gravity machine is the main separation method in the chemical industry. In the process of ultra-gravity separation, the liquid passes through the high-speed rotating filler, and under the action of ultra-gravity, it forms micro-liquids such as micro-nano-level liquid mist and droplets with a large surface area. These micro-liquids are quickly formed in the rotating filler, and then quickly condensed after being collided by the filler, and then quickly formed again, and quickly condensed, and so on. The interphase mass transfer area of ​​gas-liquid mass transfer is large and the update speed is fast. It continues to maintain a large specific surface area, greatly improving the transfer efficiency between phases.

[0003] The super gravity machine consists of a rotor, a liquid distributor and a shell. The rotor is a rotating body, and the filler is loaded inside the rotor. Under the power drive, the rotor and the filler make circular motion together. The liquid enters the liquid distributor through the delivery pipe, and after being sprayed by the liquid distributor, it enters the rotating filler from the inner edge of the filler. Under the action of centrifugal force, the liquid passes through the filler radially from the inner edge, and when it reaches the outer edge of the rotating filler, the liquid is thrown to the outer edge. After being collected, the liquid is discharged from the liquid outlet at the bottom. The gas enters the shell from the side of the rotating filler bed. After the gas fills the space area of ​​the shell, it flows from the outer edge to the inner edge of the rotating filler in the diameter direction under the action of the gas pressure, and after gathering in the central area of ​​the rotating filler, it is discharged from the gas outlet at the top.

[0004] When the super gravity machine is working, the rotor needs to rotate at high speed, and the shaft in the transmission system outputs a large amount of work and generates a large amount of heat. If the working environment temperature is too high, it will cause irreversible damage to the transmission system. Utility Model Content

In order to reduce the wear on the rotating shaft 101, a guide is fixedly arranged on the inner wall of the heat-conducting cylinder 3. The guide sleeve is made of aluminum or copper, preferably copper, which can reduce the wear on the rotating shaft 101 on the one hand, and improve the heat conduction efficiency on the other hand. The rotating shaft 101 can transfer heat to the guide sleeve, and then transfer it to the heat-conducting cylinder 3, and a water inlet pipe 202 and a water outlet pipe 203 are fixedly arranged at both ends of the cooling cylinder 2, and the water inlet pipe 202 and the water outlet pipe 203 are connected to the installation groove 201 respectively. When in use, cooling water can be passed into the installation groove 201 through the water inlet pipe 202, and then discharged from the water outlet pipe 203. The heat on the heat-conducting cylinder 3 can be taken away during the process, thereby improving the heat dissipation of the rotating shaft 101 and ensuring the reliable operation of the rotating shaft 101. A plurality of groups of fins 301 are arranged in the mounting groove 201. The fins 301 are arranged in two to ten groups, preferably five groups, and the fins 301 are in a rotating body annular structure. The two ends of the five groups of fins 301 are respectively fixedly connected to the mounting groove 201 and the heat-conducting cylinder 3, that is, the outer wall of the fin 301 is fixedly connected to the inner wall of the mounting groove 201, and the inner wall of the fin 301 is fixedly connected to the outer wall of the heat-conducting cylinder 3. The wall is fixedly connected, and welding connection is preferably adopted, and through holes 302 are opened on the five groups of fins 301. When in use, the fins 301 are fixedly arranged in the mounting groove 201, and through holes 302 are opened on the fins 301, and the angle between two adjacent groups of through holes 302 is 180°, that is to say, the multiple groups of through holes 302 are distributed in a 180° rotational staggered manner, which can increase the heat dissipation area of ​​the heat-conducting tube 3 on the one hand and improve the heat dissipation effect, and on the other hand, increase the flow path of the cooling water and further improve the heat dissipation effect.

[0026] When in use, the cooling cylinder 2 is fixedly provided on the machine body 1, and the rotating shaft 101 is rotatably provided in the cooling cylinder 2. The water inlet pipe 202 and the water outlet pipe 203 are fixedly provided on the cooling cylinder 2, so as to facilitate the introduction of cooling water into the cooling cylinder 2 and improve the heat dissipation effect of the rotating shaft 101.

[0027] Reference Figure 1 , Figure 2 and Figure 4The five groups of fins 301 are evenly distributed along the axis of the heat-conducting tube 3, that is, they are evenly arranged up and down along the axis of the heat-conducting tube 3. When in use, the mounting groove 201 can be divided into six groups of flow cavities by fixing the five groups of fins 301 evenly on the heat-conducting tube 3. During the flow of cooling water, the heat on the fins 301 can be fully taken away, thereby improving the heat dissipation effect.

There are two to twenty groups of heat-conducting sheets 303. Here, we prefer twelve groups. Two groups are fixedly arranged in six groups of flow cavities respectively, and the cross-section of the heat-conducting sheet 303 is triangular. When in use, by fixing the heat-conducting sheet 303 on the heat-conducting tube 3, the heat on the heat-conducting tube 3 can be further transferred out, so that the cooling water can take away the heat on the heat-conducting sheet 303, thereby improving the heat dissipation effect.
