Description

Technical Field

[0001] The present invention belongs to the technical field of distillation and purification, and specifically refers to a distillation and purification device for methanol production. Background Art

[0002] Methanol distillation is a refining process that separates a methanol mixture through heating and condensation. Since the boiling point of methanol (64.7°C) is significantly lower than that of water (100°C) and some organic impurities, the purification can be achieved by utilizing the boiling point difference between methanol and other components. In the original production, methanol may be mixed with other organic impurities and water, so rectification is required to improve the purity.

[0003] During the methanol distillation process, the volume of the gas formed after the liquid of unit volume is heated and volatilized becomes larger, resulting in an increase in the pressure inside the distillation kettle. As the pressure continues to rise, the speed of methanol vapor overflow will be accelerated, causing the methanol vapor to not pass through the condenser at a constant low flow rate. The methanol vapor will flow into the methanol storage tank along with the liquid methanol. The storage tank is usually designed to store liquid. If a gas-liquid mixture enters, it will increase the pressure inside the tank, leading to deformation of the tank body or failure of the seal, and even leakage. In addition, the gaseous methanol may re-condense inside the tank, releasing heat, which will also affect the temperature change of the tank body. Summary of the Invention

[0034] During specific use, first perform a cycle of condensate water. The condensate water is stored in the bottom water tank 201 and the pressurized water tank 202. Start the condensate water pump 203. The condensate water pump 203 pumps the cooling water in the bottom water tank 201 into the magnetic adsorption type pressurizing device 208. The cooling water enters the condensate inlet pipe 317 through the venturi tube 209. Then the cooling water successively passes through the top cabin inlet pipe 311, the heat conduction water cabin 302, and the top cabin drain pipe 312, and finally enters the condensate drain pipe 316 from the top cabin drain pipe 312, and then enters the preheating water pipe 408 from the condensate drain pipe 316. When the condensate water participates in the condensation of methanol vapor, the temperature of the condensate water rises. At this time, the heat of the condensate water in the preheating water pipe 408 is transferred to the stock solution in the preheating inner tank 402 through the heat conduction fins 406. Then the condensate water in the preheating water pipe 408 enters the cooling water pump 409. Use the cooling water pump 409 to pump the condensate water into the cooling inlet pipe 505. Then the condensate water in the cooling inlet pipe 505 enters the cooling drain pipe 504 through the cooling grid 502. The filtration water pump 506 pumps the condensate water in the cooling drain pipe 504 into the resin ion filter 507 to perform anion and cation filtration on the condensate water. The filtered condensate water is pumped into the storage water delivery pipe 509 through the storage water pump 508 and returns to the bottom water tank 201 and the pressurized water tank 202. The cooling water level gauges 216 in the bottom water tank 201 and the pressurized water tank 202 are used to control the opening and closing states of the pressurized water valve 214 and the bottom water valve 215, so as to supplement the condensate water. In addition, when the condensate water participates in the condensation of methanol vapor, it is necessary to start the cooling fan 503 to ventilate and cool the cooling grid 502 to further reduce the temperature of the condensate water, thereby improving the condensation efficiency. Start the distillation operation. First, inject the stock solution into the preheating inner tank 402 through the preheating water injection channel 403. Then start the preheating delivery pump 405 and open the delivery valve 106. The stock solution delivery pipe 105 is communicated with the preheating drain channel 404. The preheating delivery pump 405 pumps the stock solution in the preheating inner tank 402 into the stock solution cabin 104. At this time, start the heating control system 102. The heating control system 102 controls the heating outer cover 103, and heats the stock solution cabin 104 through the heating outer cover 103. The stock solution entering the stock solution cabin 104 is heated to the evaporation temperature of methanol, and the methanol evaporates into methanol vapor. The methanol vapor is discharged through the methanol vapor delivery pipe 108 and enters the condensation cabin 301;After the methanol vapor enters the condensation chamber 301, it diffuses into the interior of the condensation chamber 301. Since the top heat-conducting baffle 303 divides the space below the heat-conducting water chamber 302 into multiple small chambers, and since the density of the methanol vapor is lower than that of the air, the methanol vapor mainly accumulates on the top of the small chamber, that is, the bottom of the heat-conducting water chamber 302. During the diffusion process, the methanol vapor can only continue to fill the next adjacent small chamber after filling one small chamber. At the same time, the output power of the regulating electromagnet 310 can be controlled to change the suction force of the regulating electromagnet 310 on the metal suction sheet 309. When the output power of the regulating electromagnet 310 increases, the regulating electromagnet The suction force of the iron 310 on the metal suction piece 309 increases, and the metal suction piece 309 pulls the adjusting rotating rod 307, and the adjusting rotating rod 307 squeezes the reset spring 308. At the same time, the transmission rack 313 on the adjusting rotating rod 307 drives the transmission gear 306 to rotate, and the rotation of the transmission gear 306 drives the resistance rotating shaft 304 to rotate, and the rotation of the resistance rotating shaft 304 drives the resistance rotating piece 305 to rotate, and the angle between the resistance rotating piece 305 and the vertical direction decreases. Since methanol vapor is a viscous fluid, when methanol vapor diffuses to the bottom of the resistance rotating piece 305, the methanol vapor is in a divergent state, and the pressure increases along the diffusion direction. At this time, a part of the methanol vapor (branch steam) ) enters the small chamber, the methanol vapor in the small chamber contacts the heat-conducting water chamber 302 and the top heat-conducting baffle 303 for a long time, which can take away more heat, realize efficient heat transfer, and condense quickly. The branch steam diffuses in the small chamber and overflows from the lower end of the small chamber, while the other part of the methanol vapor (mainstream steam) continues to diffuse horizontally. The horizontally diffused methanol vapor (mainstream steam) will be affected by the methanol vapor (branch steam) overflowing from the lower end of the small chamber, and a vortex will be formed at the intersection, and the overall diffusion speed will become slow, which will extend the condensation time of the methanol vapor. The condensed methanol liquid will fall into the collection tank 314, and then the methanol liquid It will be discharged through the siphon 315; the condensation pressure gauge 318 can detect the pressure in the condensation chamber 301 in real time. By setting the pressure threshold, when the condensation efficiency decreases, the pressure in the condensation chamber 301 increases, and when the pressure threshold is reached, the increase electromagnet 213 is started, and the increase electromagnet 213 adsorbs the boost valve plate 211, and the boost branch pipe 210 is connected with the boost water pipe 207. Due to the Venturi effect, the condensed water in the Venturi pipe 209 will attract the condensed water in the boost branch pipe 210, thereby increasing the delivery volume of condensed water to improve the condensation efficiency; in addition, in actual production, the number of each mechanism can be increased according to the scale of the enterprise to improve the overall production efficiency. ;
