[0024] Since the existing tower sections have poor corrosion resistance and the gas-liquid contact is not tight enough, and the constant temperature effect in the tower is poor, resulting in low material separation efficiency and low output of production materials, the inventors have provided enameled tower sections after research, which have higher corrosion resistance, close gas-liquid contact, and good constant temperature effect, thereby increasing the distillation efficiency and improving the output of production materials.

[0025] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0026] Please refer to Figure 1 An embodiment of the present invention provides an enamel tower section, including a tower section assembly 100 and a filler constant temperature assembly 200.

[0027] Please refer to Figure 2The tower section assembly 100 includes a top tower section 110, an intermediate tower section 120 and a tail tower section 130. The top tower section 110, the intermediate tower section 120 and the tail tower section 130 are fixedly connected in sequence by flanges. The intermediate tower section 120 is provided with multiple, the top tower section 110 is provided with an outlet pipe 140, and the tail tower section 130 is provided with an inlet pipe 150 and a liquid outlet pipe 160; the packing thermostatic assembly 200 includes a liquid distribution member 210, a packing member 220 , liquid redistribution member 230 and heating jacket 240. The liquid distribution member 210 is fixedly connected to the top tower section 110. The fillers 220 are respectively filled in the top tower section 110, the middle tower section 120 and the tail tower section 130. The liquid redistribution member 230 is fixedly connected to the top of the middle tower section 120 and the tail tower section 130. The heating jacket 240 is respectively sleeved on the tower walls of the top tower section 110, the middle tower section 120 and the tail tower section 130. The inner tower walls of the top tower section 110, the middle tower section 120 and the tail tower section 130 are glass-lined with glaze powder, which is corrosion-resistant. The tower bodies are connected by flanges, and the middle tower section 120 is provided with several flanges. During use, the mixed gas enters the tower section from the air inlet pipe 150, and at the same time, the liquid distribution member 210 sprays the absorption liquid into the tower. The mixed gas and the absorption liquid move toward each other and are in close contact with the surface of the packing member 220 in the tower section, thereby fully transferring mass. During the mixing period, when the absorption liquid passes through the top of the intermediate tower section 120, it falls on the liquid redistribution member 230. After being redistributed by the liquid redistribution member 230, the absorption liquid falls back to the packing member 220 on the intermediate tower section 120, and the mixed gas is in close contact with the absorption liquid again. During the operation, by setting up a number of intermediate tower sections 120 and a number of The filler element 220 allows the mixed gas to repeatedly contact the absorption liquid, resulting in closer gas-liquid contact during the distillation process, thereby improving separation efficiency and distillation efficiency, thereby increasing the output of production materials. The heating jacket 240 ensures the temperature within the tower body and maintains a constant temperature, thus solving the problem of poor corrosion resistance of existing tower sections. The simple contact between gas and liquid in a closed space results in insufficient gas-liquid contact, and the tower has poor temperature control, resulting in low material separation efficiency and low production material output. The outlet pipe 140 includes a connecting cone 141 and an outlet pipe body 142. The connecting cone 141 is fixedly connected to the top of the top tower section 110, and the outlet pipe body 142 is fixedly connected to the connecting cone 141. The gas passes through the connecting cone 141 and enters the next process flow through the outlet pipe body 142. The outlet pipe body 142 facilitates the connection of pipelines. The liquid outlet pipe 160 includes an inverted cone 161 and a liquid outlet body 162. The inverted cone 161 is fixedly connected to the bottom end of the tail tower section 130, and the liquid outlet body 162 is fixedly connected to the inverted cone 161. The inverted cone 161 is convenient for collecting the used absorption liquid, and the liquid outlet body 162 is used to drain the absorption liquid.

[0028] Please refer to Figure 3 The liquid distribution member 210 includes a liquid inlet pipe 211, a spray plate 212, and spray nozzles 213. One end of the liquid inlet pipe 211 extends into the top tower section 110. The spray plate 212 is fixedly connected to the liquid inlet pipe 211. The spray nozzles 213 are evenly arranged on the spray plate 212. The absorption liquid enters the spray plate 212 through the liquid inlet pipe 211 and is then sprayed out through the spray nozzles 213.

[0029] Please refer to Figure 4 The packing member 220 includes a packing support frame 221 and a ceramic corrugated packing 222. The packing support frame 221 is fixedly connected to the top tower section 110, the middle tower section 120 and the tail tower section 130. The packing support frame 221 is provided in two and fixed up and down. The ceramic corrugated packing 222 is filled between the two packing support frames 221. The ceramic corrugated packing 222 is composed of packing units of the same geometric shape. The turbulence of an extremely thin liquid film and the inclined and tortuous channels of the airflow can promote the airflow without blocking the airflow, so that the absorption liquid and the mixed gas can fully contact on the surface of the liquid film. The ceramic corrugated packing 222 is semicircular and is staggered from bottom to top in the tower. Staggered stacking is conducive to full contact between gas and liquid.

[0030] Please refer to Figure 5 The liquid redistribution element 230 includes a liquid storage disc 231 and a redistributor 232. The liquid storage disc 231 is fixedly connected to the top of the middle tower section 120 and the tail tower section 130. The liquid storage disc 231 defines a liquid storage tank 233, and the redistributors 232 are sequentially arranged and fixed within the liquid storage tank 233. The sprayed absorption liquid passes through the packing 220 of the top tower section 110, flows into the liquid storage disc 231, and then flows back down through the redistributor 232, thereby ensuring sufficient contact between the absorption liquid and the mixed gas within the middle tower section 120. The redistributor 232 includes through-hole columns 2321, baffles 2322, and connecting curved plates 2323. The through-hole columns 2321 are arranged in sequence and fixed in the liquid storage tank 233. The height of the through-hole columns 2321 is less than the height of the tank wall of the liquid storage tank 233. The baffles 2322 are fixedly connected to the top of the through-hole columns 2321 via the connecting curved plates 2323. The absorption liquid in the middle flows onto the adjacent baffles 2322 and then flows into the through-hole columns 2321. The absorption liquid nearby accumulates in the liquid storage tank 233 and flows down through the through-hole columns 2321 when it exceeds a certain height, thus preventing the absorption liquid from frequently contacting the mixed gas on the tower wall. A certain gap exists between the baffles 2322 and the through-hole columns 2321, so as not to affect the passage of the mixed gas.

[0031] Please refer to Figure 6The heating jacket 240 includes a jacket body 241, an oil inlet pipe 242, an oil outlet pipe 243, a three-way oil pump 244 and an oil replenishing pipe 245. The jacket body 241 is sleeved on the tower walls of the top tower section 110, the middle tower section 120 and the tail tower section 130. One end of the oil inlet pipe 242 is fixedly connected to one side of the jacket body 241, and one end of the oil outlet pipe 243 is fixedly connected to the other side of the jacket body 241. The other end of the oil inlet pipe 242 and the other end of the oil outlet pipe 243 are respectively fixedly connected to the three-way oil pump 244, and the oil replenishing pipe 245 is fixedly connected to the three-way oil pump 244. There is a coiled coil inside the jacket body 241. The oil inlet pipe 242 is connected to one end of the coiled coil, and the oil outlet pipe 243 is connected to the other end of the coiled coil. The oil replenishing pipe 245 is used to replace and replenish the heat transfer oil in the coiled coil. The heat transfer oil enters the jacket body 241 through the three-way oil pump 244. The jacket body 241 keeps the tower sections in a constant temperature state. When the temperature of the heat transfer oil in the jacket body 241 drops to a certain extent, part of the oil is discharged through the oil outlet pipe 243 and the three-way oil pump 244, and then the heat transfer oil with a higher temperature is replenished through the oil replenishment pipe 245, thereby ensuring that the heat transfer oil can circulate and always remain in a rough temperature range, so that the tower body is always in a relatively stable constant temperature environment.

[0032] In summary, the working principle of the enamel tower section of the embodiment of the utility model is as follows: when in use, the mixed gas enters the tower section from the air inlet pipe 150, and at the same time the absorption liquid enters the spray plate 212 through the liquid inlet pipe 211, and is then sprayed into the tower through the spray nozzle 213. The mixed gas and the absorption liquid move in opposite directions. When the absorption liquid passes through the ceramic corrugated packing 222 in the multi-section tower section, the absorption liquid and the mixed gas are in full contact on the liquid film surface on the ceramic corrugated packing 222. During the mixing period, when the absorption liquid passes through the top of the middle tower section 120, the absorption liquid in the middle splashes onto the side baffle 2322 and flows into the through-hole column 2321 along the baffle 2322. The absorption liquid next to it is stored in the liquid storage tank 233. When it exceeds a certain height, it flows down through the through-hole column 2321, so that the absorption liquid is redistributed, and the absorption liquid falls back into the ceramic corrugated packing in the middle tower section 120. On the material 222, the mixed gas is in close contact with the absorption liquid again, and the absorption liquid and the mixed gas are in multi-stage contact with the multi-stage ceramic corrugated packing 222. During operation, by setting up several intermediate tower sections 120 and multi-stage ceramic corrugated packing 222, the mixed gas is continuously and repeatedly in contact with the absorption liquid, so that the gas-liquid contact is closer during the distillation process, thereby improving the separation efficiency, making the distillation efficiency higher, and thus improving the output of production materials. Through the three-way oil pump 244 and the multi-stage pipeline, the heat transfer oil in the jacket body 241 is always in a rough temperature range, so that the tower body is always in a relatively stable constant temperature environment, thereby solving the problems of poor corrosion resistance of the existing tower sections, insufficient gas-liquid contact, and poor constant temperature effect in the tower, which leads to low material separation efficiency and low output of production materials.
