Description

Technical Field

[0001] The invention relates to the technical field of separation devices, in particular to a diethyl itaconate separation device. Background Art

[0002] Diethyl itaconate is an organic compound, a colorless, transparent, low-toxic organic substance, which has the ability to dissolve polymers and can be dissolved in most organic solvents, such as aromatic hydrocarbons, alcohols, ethers, ketones, organic acids and esters. Diethyl itaconate is very important in the chemical synthesis industry because it contains double bonds at the α and β positions, has a more active reaction property, and is easy to undergo addition reactions. When diethyl itaconate is used in the chemical synthesis industry, it often produces surplus and causes waste, so the surplus diethyl itaconate needs to be separated, collected and processed.

[0003] For example, the announcement number is: CN221998946U (named as a diethyl maleate extraction and separation device), which includes an extraction cylinder, a stirring assembly is arranged inside the extraction cylinder, and the stirring assembly includes a mounting plate, a plurality of fixing rods are fixedly connected to the four corners of the rear side of the mounting plate, and the ends of the fixing rods are fixedly connected to the inner wall of the extraction cylinder, a first fixing frame is fixedly connected to the upper end of the front side of the mounting plate, a rotating column is rotatably connected to the bottom of the first fixing frame, a second fixing frame is fixedly connected to the middle part of the front side of the mounting plate, a through hole is opened in the middle part of the second fixing frame, a third fixing frame is fixedly connected to the lower end of the front side of the mounting plate, a curved block is rotatably connected to the upper end of the third fixing frame, and a driving gear is fixedly connected to the top of the curved block. A transmission rod is fixedly connected to the top of the driving gear, and the top of the transmission rod passes through a through hole and is fixedly connected to the bottom of the rotating column. A servo motor is provided to drive the rotating column to rotate, so that the transmission rod rotates eccentrically, and the upper and lower ends of the transmission rod will swing in an "8" shape with the curved block as the center of the circle. Under the transmission action of the belt, the driven column, the driving gear and the driven gear, the transmission rod will be driven to rotate, so that the stirring shaft drives the stirring rod and the stirring claw to rotate, thereby improving the stirring efficiency, increasing the mass transfer speed of the reaction materials, thereby promoting the improvement of the reaction rate, shortening the reaction time, and improving the production efficiency. Improving the stirring efficiency can reduce unnecessary reaction time and energy consumption, reduce production costs, and improve production benefits.

[0022] 1. The diethyl itaconate liquid of the present invention is discharged into the interior of the first separation tank or the second separation tank through a feed conduit. The first separation tank is used for reversible reaction separation, and dilute sulfuric acid is used as a catalyst. The reversible reaction hydrolysis generates itaconic acid and ethanol. The second separation tank is used for irreversible reaction separation, and sodium hydroxide is used as a catalyst to produce sodium itaconate solid crystals and ethanol. The staff can choose to recover it in the form of liquid or solid according to the needs. After the solid form is recovered, the sodium itaconate solid crystals react with acid to produce itaconic acid again. The itaconic acid and ethanol recovered in the form of liquid or solid can be reused to prepare diethyl itaconate, thereby avoiding the problems of waste and excessive consumption of diethyl itaconate in industry and improving the selectivity of separation and recovery.

[0023] 2. After the steam is discharged into the condenser, it enters the curved coil. The interior of the condenser is pre-filled with cold water. The cold water cools the entire curved coil and liquefies it and performs heat exchange, so that the cold water is heated. The drain valve is opened to discharge the hot water, and the drain valve is opened to discharge the separated and recovered liquid. The discharged hot water is injected into the inner cavity. After that, diethyl itaconate is injected into the central inner tube, and the hot water obtained by steam heat exchange is used to pre-heat the diethyl itaconate in a water bath, so that the diethyl itaconate has a certain temperature before entering the first separation tank or the second separation tank, thereby saving the energy consumption required for heating by the electric heating plate.

[0024] 3. After the driving motor is powered on, it drives the linkage shaft and the stirring paddle to rotate and stir, thereby accelerating the reaction rate. The linkage shaft rotates while driving the driving gear, which drives the transmission gear meshing with it to rotate synchronously, thereby enabling the small generator to generate electricity. The generated AC electricity is processed by the rectifier and then injected into the battery box through the transmission line for storage and standby. The electric energy required for heating the electric heating plate is supplied by the battery box, and the electric energy of the battery box is supplied by the small generator. The entire separation device only needs to connect two driving motors and the electric push rod to an external power supply, which greatly saves the energy consumption during the recovery and separation of diethyl itaconate.

[0025] 4. When taking materials, the linkage top platform and the two top cover plates are lifted up by the electric push rod, which is convenient for taking out the sodium itaconate solid crystals in the second separation tank, and also convenient for pre-loading cold water into the interior of the condensation cylinder through the plug-in interface.

The diethyl itaconate liquid is loaded inside the central inner tube 34. The two driving motors 6 are connected to the external power supply at the same time. The first valve 38 and the second valve 39 are opened at the same time, so that the diethyl itaconate liquid is discharged into the first separation tank 3 or the second separation tank 4 through the discharge conduit 15. The staff can choose to recover it in the form of liquid or solid according to the needs. After the first valve 38 and the second valve 39 are opened at the same time, the diethyl itaconate is discharged into the first separation tank 3 or the second separation tank 4 through the discharge conduit 15, and then the dilute sulfuric acid is added. Or sodium hydroxide is poured into the first separation tank 3 or the second separation tank 4 as a catalyst, and the driving motor 6 drives the linkage shaft 31 and the stirring paddle 30 to rotate and stir after being powered on. The linkage shaft 31 rotates while driving the driving gear 32, and the driving gear 32 drives the transmission gear 33 meshing therewith to rotate synchronously, thereby enabling the small generator 7 to generate electricity.

After the reaction is completed, sodium itaconate and ethanol are in a miscible state in the first separation tank 3, and the sodium itaconate solid crystals in the second separation tank 4 are located in the ethanol liquid. Then, the power switch 22 is pressed. The battery box 21 supplies power to the electric heating plate 29 in the placement slot 28 through the connecting wire 23. The electric heating plate 29 releases heat after being powered on, and conducts heat to the first separation tank 3 and the second separation tank 4, and the temperature is controlled by the temperature regulator 40. The boiling point of ethanol is lower than that of itaconic acid. The ethanol is first evaporated and discharged through the steam conduit 16 by heating, and then the itaconic acid is discharged through another steam conduit 16. The second separation tank 4 only needs to heat and discharge the ethanol vapor. After the steam is discharged into the condensing cylinder 18, it enters the curved coil 37.
