Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of distillation and purification, and specifically relates to a distillation and purification device for methanol production. Background Art
[0002] Methanol distillation is a refining process that separates methanol mixtures through heating and condensation. Because methanol's boiling point (64.7°C) is significantly lower than that of water (100°C) and some organic impurities, the boiling point difference between methanol and other components can be exploited for purification. During initial production, methanol may be mixed with other organic impurities and water, necessitating distillation to improve purity.
[0003] During the methanol distillation process, the volume of gas formed after the unit volume of liquid evaporates due to heat increases, causing the pressure in the distillation kettle to increase. As the pressure continues to rise, the rate of methanol vapor overflow will accelerate, resulting in the inability of methanol vapor to pass through the condenser at a constant low flow rate. Methanol vapor will flow into the methanol storage tank along with liquid methanol. Storage tanks are usually designed to store liquids. If a gas-liquid mixture enters, the pressure in the tank will increase, causing the tank to deform or the seal to fail, or even leak. In addition, gaseous methanol may re-condense in the tank, releasing heat, and also affecting the temperature change of the tank. Summary of the Invention

[0021] The beneficial effects of a distillation and purification equipment for methanol production provided by this solution are as follows:
[0022] (1) A heating mechanism is provided to quickly heat the raw liquid, and the electric heating method makes the heating temperature more accurate, which can effectively separate components with different boiling points. The electric heating directly heats the raw liquid tank through electromagnetic induction, without the need for external fuel combustion, which significantly reduces the risk of fire;

By adding an electromagnet to absorb the boosting valve plate, and by using a venturi to suck the condensed water in the boosting water tank, the condensed water can be pressurized without additional boosting equipment.

[0024] (3) The condensation mechanism is set up to adjust the electromagnet to adsorb the metal suction piece, and the power (suction force) of the electromagnet is controllable and adjustable. The resistance rotor is driven by the metal suction piece to rotate, thereby changing the diffusion direction of the methanol vapor in the condensation chamber. The characteristic of methanol vapor as a viscous fluid is used to form a vortex at the intersection, and the overall diffusion speed becomes slow, thereby extending the condensation time of the methanol vapor and improving the condensation efficiency.
[0025] (4) Setting up a preheating mechanism to use the condensed water that absorbs the heat of methanol vapor to preheat the raw liquid can reduce the consumption of external energy (electricity). The raw liquid needs to be preheated to a certain temperature before it can evaporate efficiently. If it is preheated by condensed water, some of the high energy consumption heating stages can be directly skipped, thus speeding up the distillation process.
[0026] (5) Setting up a cooling mechanism to further cool the condensed water can increase the amount of heat that can be absorbed by a unit volume of cooling water, thereby improving the heat exchange efficiency between the condensed water and methanol vapor. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] When in use, a condensed water cycle is first performed, and the condensed water is stored in the bottom water tank 201 and the boost water tank 202. The condensed water pump 203 is started, and the condensed water pump 203 pumps the cooling water in the bottom water tank 201 into the magnetic booster device 208. The cooling water enters the condensed water inlet pipe 317 through the venturi tube 209, and then the cooling water passes through the top cabin water inlet pipe 311, the heat conduction cabin 302 and the top cabin drain pipe 312 in sequence, and finally enters the condensed water drain pipe 316 through the top cabin drain pipe 312, and then enters the preheated water pipe 408 through the condensed water drain pipe 316. When the condensed water participates in the condensation of methanol vapor, After that, the condensed water temperature rises. At this time, the heat of the condensed water in the preheating water pipe 408 will be transferred to the raw liquid in the preheating inner tank 402 through the heat conducting fins 406. Then the condensed water in the preheating water pipe 408 enters the cooling water pump 409, and the cooling water pump 409 uses the condensed water pump 203 to enter the cooling water inlet pipe 505. Then, the condensed water in the cooling water inlet pipe 505 passes through the cooling grid 502 and enters the cooling drain pipe 504. The filtered water pump 506 pumps the condensed water 203 in the cooling drain pipe 504 into the resin ion filter 507 to filter the condensed water. The filtered condensed water is then stored. The water pump 508 pumps the water into the storage water pipe 509 and returns it to the bottom water tank 201 and the boost water tank 202. The cooling water level gauges 216 in the bottom water tank 201 and the boost water tank 202 are used to control the switch status of the boost water valve 214 and the bottom water valve 215 to replenish the condensed water. In addition, after the condensed water participates in the condensation of the methanol vapor, the cooling fan 503 needs to be turned on to ventilate and cool the cooling grid 502 to further reduce the temperature of the condensed water, thereby improving the condensation efficiency. To start the distillation operation, first, the raw liquid is injected into the preheating tank 402 through the preheating water injection channel 403. Then, the preheating delivery pump 405 is started, the delivery valve 106 is opened, the raw liquid delivery pipe 105 is connected to the preheating drainage channel 404, and the preheating delivery pump 405 pumps the raw water in the preheating inner tank 402 into the raw liquid tank 104. At this time, the heating control system 102 is started, and the heating control system 102 controls the heating outer cover 103. The raw liquid tank 104 is heated by the heating outer cover 103. The raw liquid entering the raw liquid tank 104 is heated to the evaporation temperature of methanol. The evaporated methanol turns into methanol vapor, which is discharged into the condensation chamber 301 through the methanol vapor delivery pipe 108;After the methanol vapor enters the condensing chamber 301, it diffuses into the interior of the condensing chamber 301. Since the top heat-conducting partition 303 divides the space below the heat-conducting heat chamber 302 into multiple small chambers, and since the density of methanol vapor is lower than that of air, the methanol vapor mainly accumulates on the top of the small chamber, that is, the bottom of the heat-conducting heat 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 piece 309. When the output power of the regulating electromagnet 310 increases, the regulating electromagnet 310 The suction force of the iron 310 on the metal suction piece 309 increases, and the metal suction piece 309 pulls the adjustment rotating rod 307, which squeezes the return spring 308. At the same time, the transmission rack 313 on the adjustment 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 the 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 bottom 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 bottom of the small chamber, and a vortex will be formed at the intersection. The overall diffusion speed becomes slow, which prolongs the condensation time of the methanol vapor. The condensed methanol liquid will fall into the collection tank 314, and then the methanol liquid The condensate is discharged through the siphon 315. The condensation pressure gauge 318 can monitor the pressure in the condensation chamber 301 in real time. By setting a pressure threshold, when the condensation efficiency decreases and the pressure in the condensation chamber 301 increases, reaching the pressure threshold, the boosting electromagnet 213 is activated, which attracts the boosting valve plate 211. The boosting branch pipe 210 is connected to the boosting water pipe 207. Due to the Venturi effect, the condensate in the Venturi tube 209 attracts the condensate in the boosting branch pipe 210, thereby increasing the condensate delivery volume and improving the condensation efficiency. In addition, in actual production, the number of each unit can be increased according to the scale of the enterprise to improve overall production efficiency.
