[0002] A distillation tower is a tower-type gas-liquid contact device for distillation. It uses the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, to transfer the light components (low boiling substances) in the liquid phase to the gas phase, and the heavy components (high boiling substances) in the gas phase to the liquid phase, thereby achieving the purpose of separation.

It is necessary to wait until the waste slag is cooled before it can be discharged. During the waiting period for the slag to be discharged, the distillation tower cannot be used normally, which greatly reduces the working efficiency of the distillation tower. Utility Model Content

Example

[0021] Improvement based on the first embodiment: a distillation tower that is easy to discharge slag, comprising a distillation tower body 1 and two groups of preheating tanks 2 symmetrically arranged in the left and right directions on the front side of the distillation tower body 1, both sides of the top of the distillation tower body 1 are connected with main pipes 9, the surface of the preheating tank 2 is fixedly connected with a heating jacket 3, the outer side of the top of the heating jacket 3 and the top of the preheating tank 2 close to each other are connected with fixed pipes 5, each group of fixed pipes 5 is provided with a solenoid valve, the design of the fixed pipe 5, on the one hand, is convenient for adding heat transfer oil to the heating jacket 3, on the other hand, the solenoid valve can be used to release pressure in time when the air pressure in the heating jacket 3 and the preheating tank 2 is too high, the tops of the two groups of preheating tanks 2 far away from each other are connected with a feeding pipe 4, the bottom end of each group of preheating tanks 2 is connected with a slag discharge pipe 6, and the bottom end of the slag discharge pipe 6 passes through the heating jacket 3 and is directed to the bottom of the preheating tank 2. The bottom of each preheating tank 2 is fixedly connected with a guide inclined plate 17 used in conjunction with the slag discharge pipe 6 on both sides of the bottom. The design of the guide inclined plate 17 can guide the waste slag so that it can be concentrated at the center of the bottom of the preheating tank 2 to facilitate slag discharge. The bottom of the heating sleeve 3 is fixedly connected with a small vibration motor 18 used in conjunction with the slag discharge pipe 6 on both sides. The design of the small vibration motor 18 can make the heating sleeve 3 and the preheating tank 2 vibrate synchronously, further assisting in material discharge and avoiding waste slag accumulation. Auxiliary valves are provided on the feeding pipe 4 and the slag discharge pipe 6. The bottoms of the two groups of heating sleeves 3 away from each other are sequentially embedded with a plurality of groups of heating rods 7 for heating the heat transfer oil in the heating sleeves 3 in a transverse direction in the front-to-back direction. Each group of preheating tanks 2 is connected with a vertical pipe 8, and the top of the vertical pipe 8 passes through the heating The sleeve 3 is connected to the main pipe 9, and a venturi tube 10 is arranged at the middle section of the main pipe 9. The design of the venturi tube 10 can further accelerate the steam. A first non-return valve 11 is arranged at one end of the main pipe 9 close to the distillation tower body 1. By arranging the vertical pipe 8, the main pipe 9, the heating sleeve 3, multiple groups of heating rods 7 and two groups of preheating tanks 2, multiple preheating structures can be added to the original distillation tower body 1, so that all slag discharge work is carried out in the preheating tank 2, and the alternating use of multiple groups of preheating tanks 2 can effectively avoid stopping to clean up the waste slag in the distillation tower body 1, which greatly improves the distillation efficiency. The end of the main pipe 9 away from the distillation tower body 1 is connected to a fixed cylinder 12, and a plurality of groups of air inlet holes 13 are evenly arranged on the front of each group of fixed cylinders 12. A fan 15 is embedded on the back side, and multiple groups of electric heating wires 16 are sequentially arranged in the left and right directions in each group of fixed cylinders 12. By arranging the fan 15, a certain thrust can be given to the steam in the main pipe 9, and the increase in flow rate can further assist in extracting the steam from the preheating tank 2, so as to quickly send the steam into the distillation tower body 1 for distillation operation, and the design of the multiple groups of electric heating wires 16 and the air inlet 13 can heat the air in the fixed cylinder 12, so that the fan 15 can further heat the steam while pushing, so as to avoid the temperature of the steam from decreasing during the transmission process. Both sides of the bottom of the heating sleeve 3 are fixedly connected with support frames, and a controller is arranged on the left side of one group of support frames. A second one-way valve 14 is arranged at one end of the main pipe 9 close to the fixed cylinder 12.The second one-way valve 14 is located on the front of the vertical pipe 8. The design of the second one-way valve 14 prevents steam from directly entering the fixed cylinder 12.

[0022] In the utility model, the user pre-injects the liquid raw materials into the preheating tank 2 through the feeding pipe 4, and then the user turns on the multiple groups of heating rods 7 on one group of heating sleeves 3 through the controller, and the heating rods 7 heat the heat-conducting oil in the heating sleeve 3, so that the liquid raw materials in the preheating tank 2 can be heated. As the temperature continues to rise, the liquid raw materials will generate steam when heated, and the steam is transported to the distillation tower body 1 through the vertical pipe 8 and the main pipe 9, and the user turns on the fan 15 and the electric heating wire 16 synchronously through the controller, the electric heating wire 16 heats the air in the fixed cylinder 12, and the fan 15 blows the hot air into the main pipe 9, so that the steam can be accelerated. At the same time, the increase in flow rate will form a certain negative pressure. At the same time, under the secondary acceleration of the venturi tube 10, the steam can be quickly transported to the distillation tower body 1, and then the distillation tower body 1 performs distillation operation on the steam. After the liquid raw material in one group of preheating tanks 2 is evaporated, a lot of waste residue will accumulate at the bottom. At this time, the user turns on the multiple groups of heating rods 7 on another group of heating sleeves 3, that is, the work can be carried out continuously. The alternating use of the two groups of preheating tanks 2 effectively avoids the need to stop the machine to clean the waste residue. Then the user only needs to turn on the small vibration motor 18 and the auxiliary valve on the slag discharge pipe 6. As the small vibration motor 18 continues to vibrate, the waste residue will be quickly discharged through the slag discharge pipe 6.

[0023] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
