Description

Technical Field

[0001] The invention relates to the technical field of distillation towers, in particular to a high-efficiency and energy-saving distillation tower used in chemical production. Background Art

[0002] The distillation tower in chemical production is a key equipment for separation of mixtures. It separates high-purity components through distillation operation based on the difference in volatility of each component in the mixture. The working principle of the distillation tower is similar to fractional distillation, but more sophisticated and efficient. During the distillation process, the raw material mixture enters the distillation tower from the middle or lower part of the tower, and exchanges heat and mass with the rising steam when passing through the tower plates or packings. The volatile components rise with the steam, while the non-volatile components remain in the liquid phase and continue to fall. At the top of the tower, the volatile components are condensed and partially refluxed into the tower to maintain a constant composition at the top of the tower; at the bottom of the tower, the non-volatile components are condensed and partially refluxed into the tower to maintain a constant composition at the top of the tower; at the bottom of the tower, the non-volatile components are condensed and partially refluxed into the tower to maintain a constant composition at the top of the tower. The volatile components are concentrated and discharged from the system. By adjusting the operating parameters such as reflux ratio, tower top temperature, tower bottom temperature, etc., efficient separation of the mixture can be achieved. Distillation towers are widely used in chemical production, such as oil refining, petrochemicals, fine chemicals, pharmaceuticals, food and other industries. It can be used to separate various liquid mixtures, such as hydrocarbon mixtures, alcohol mixtures, acid mixtures, etc., to obtain high-purity products or intermediates. With the continuous development of chemical technology, the design and operation of distillation towers are becoming more advanced and intelligent, providing a more reliable and efficient separation method for chemical production.

[0003] In the prior art, such as Chinese patent number: CN116785745A, a distillation tower for the production of chemical raw materials is provided, including a distillation tower body, the upper and lower ends of the rear wall of the distillation tower body are respectively provided with a collecting mechanism and a filtering and discharging mechanism, the inner bottom wall of the distillation tower body is fixedly embedded with a spiral heating tube, the upper side wall of the distillation tower body is movably penetrated with a hollow stirring rod, the outer wall of one end of the hollow stirring rod located inside the distillation tower body is fixedly connected with a plurality of stirring blades and nozzles, and the outer wall of one end of the hollow stirring rod located outside the distillation tower body is provided with a rotating mechanism. The present invention can drive each stirring blade and each nozzle to move over a large range in the distillation tower body by rotating and reciprocating up and down hollow stirring rods at the same time, thereby achieving large-scale stirring of raw materials and large-scale flushing of the inner wall of the distillation tower body, improving the distillation efficiency of raw materials while also improving the flushing range and flushing effect of the inner wall of the distillation tower.

[0004] In the operation of traditional distillation towers, the flow state of the gas-liquid two-phase in the tower is difficult to reach the ideal state, which leads to limited mass transfer and heat transfer efficiency, thus affecting the separation effect. At the same time, the design of the tower tray often ignores the interaction mechanism between the gas-liquid two-phase, resulting in uneven liquid distribution, increased droplet entrainment and backmixing.

[0005] 1. Gas-liquid two-phase flow problem: Inside the distillation tower, the flow state of the gas-liquid two-phase is crucial to the mass transfer and heat transfer process. However, due to the complexity of fluid dynamics, there are often phenomena such as uneven flow, eddy currents, and dead zones inside the tower, which lead to a decrease in mass transfer and heat transfer efficiency and affect the separation effect.

[0006] 2. Defects in tray design: Traditional tray design often focuses on structural strength and durability, while neglecting in-depth research on the interaction mechanism between the gas and liquid phases. This leads to uneven distribution of liquid on the tray, increases the occurrence of droplet entrainment and backmixing, and further reduces the separation efficiency. Summary of the invention

These mechanisms work together to achieve smooth transportation and distillation processing between chemical liquids. In particular, a group of rollers 12 are equipped at the bottom of the main plate 11 to ensure the flexible movement of the device on the ground, which is convenient for overall transportation and deployment. During operation, the liquid storage mechanism 2 serves as the starting point of the whole system.

A liquid level sensor is provided inside the tank. The liquid inventory is monitored in real time to ensure timely replenishment. In addition, in order to prevent the liquid from chemically reacting or precipitating during storage, the liquid storage tank is also equipped with a stirring device to keep the liquid uniform by rotating at a low speed. The chemical liquid is first sent to the liquid storage tank 21 for pre-storage. The adsorption tube 26 is firmly fixed on the linkage plate 23 using two U-shaped locking rods 25.

Using the gravity, the liquid flows freely between the plates and in the inner groove 341 until it finally converges to the bottom of the distillation tank 31. The heating plate 312 built into the distillation tank 31 generates high temperature after power is turned on, heats the liquid, and causes it to evaporate into steam. During the rising process, the steam is heated by multiple The adsorption disk 351 captures and guides the steam to the top of the distillation tank through the connecting pipe A35, and finally collects the steam through the gas valve 33 and transports it to the condensation mechanism 4 along the transmission pipe 331. In the condensation mechanism 4, the top of the condensation tank 41 is connected to the external refrigeration equipment through the external pipe 421 to ensure that the low temperature environment is maintained in the tank. The cooled steam condenses into liquid under the action of the condensation pipe 42, and then drips to the bottom of the condensation tank under the action of gravity, and is finally discharged through the output pipe 46 to complete the entire distillation process.
