Description

Technical Field

[0001] The utility model relates to the technical field of glycerol production, and specifically relates to an integrated synthesis and purification device for glycerol production. Background Technique

[0002] Glycerol, namely glycerin, is a widely used chemical raw material and is widely used in multiple industries such as medicine, food, and cosmetics. Traditional glycerol production methods mainly include the natural glycerol production method using natural oils and fats as raw materials and the synthetic glycerol production method using synthetic raw materials as raw materials. In these production methods, the purification of glycerol is a key step, involving complex physical and chemical processes, including multiple links such as distillation, cooling, neutralization, and filtration.

[0003] Existing glycerol production equipment usually includes a stirring settler, a centrifugal filtration separator, an alkali neutralizer, a vacuum dryer, etc. However, there are some deficiencies in these existing devices. For example, it is impossible to achieve integrated automated synthesis production, and it is rather cumbersome to use other devices or manual operations during the process of transporting the produced glycerol for purification. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides an integrated synthesis and purification device for glycerol production.

[0005] The technical solution of the utility model is: an integrated synthesis and purification device for glycerol production, including a hydrolysis reaction kettle, a distillation kettle arranged on one side of the hydrolysis reaction kettle, a condenser assembly arranged at the drain outlet of the distillation kettle, and a purification component arranged directly below the liquid outlet of the condenser assembly; the hydrolysis reaction kettle, the distillation kettle, and the condenser assembly are sequentially connected through pipelines;

[0006] The condenser assembly includes a condensation pipeline with an inlet end connected to the drain outlet of the distillation kettle, a condensation housing wrapped on the outer surface of the condensation pipeline, and a refrigeration medium storage cavity connected to the condensation housing through a conduit and a pump body;

[0007] The purification component includes a disk body, a liquid-carrying cavity and a dirt-carrying cavity arranged at the bottom of the disk body, and a purification pool rotatably and sealingly arranged on the disk body with the bottom connected to a rotating motor; two groups of corresponding contact sensors are arranged on the bottom of the purification pool and the top of the disk body; first and second electric control valves respectively communicating with the liquid-carrying cavity and the dirt-carrying cavity are arranged on the bottom of the purification pool and the top of the disk body;

[0008] The liquid outlet of the condensation pipeline is located directly above the non-drainage and non-discharge cavity of the purification pool; an electronic valve is arranged at the liquid outlet of the condensation pipeline.

[0009] Description: When the purification tank rotates, the cavity that originally holds liquid glycerol rotates above the liquid-carrying cavity where liquid needs to be discharged. The electronic valve at the liquid outlet of the condensation pipeline is closed during rotation and opened when stationary. This design allows the purification and adsorption work to continue while glycerol is being discharged and the filter material is being removed, improving production efficiency.

[0010] Furthermore, a refrigeration device is provided inside the refrigerant storage cavity, and the refrigerant is also filled inside it.

[0011] Description: The refrigerant can help the refrigeration equipment absorb heat more effectively, thereby improving the overall refrigeration efficiency. The design of the refrigerant storage cavity and the condensation shell can prevent refrigerant leakage during use, saving energy and being environmentally friendly.

[0012] Furthermore, the interior of the purification tank is circumferentially divided into three equal-sized purification cavities by partition plates, and electric control stirring paddles and weighing sensors are arranged inside each purification cavity.

[0013] Description: By dividing the purification tank into three purification cavities, glycerol discharge, filter material removal, and glycerol purification can be carried out simultaneously, thereby improving the purification efficiency and simplifying the purification process; each purification cavity is equipped with an electric control stirring paddle and a weighing sensor, which can monitor and adjust the stirring speed during the purification process in real time to ensure the stability of the purification process and the consistency of product quality, and can judge the liquid addition amount. After exceeding the threshold, the liquid addition stops and sufficient stirring and purification are carried out.

[0014] Furthermore, a braking module is also provided inside the condensation shell. The braking module includes an impeller rotatably arranged on the inner wall of the condensation shell through a shaft rod, and a guide plate arranged inside the condensation shell.

[0015] Description: Using the flow of the refrigeration medium at the through holes of the guide plate to push the impeller to rotate and drive the gear to rotate, saving driving energy, enabling slow and continuous driving, starting during cooling, and the braking module also naturally stopping when production stops, which is convenient for control.

[0016] Even further, the purification assembly further includes a feeding module. The feeding module includes a support plate, a gear rotatably arranged on the support plate, a rotating cylinder meshing with the gear and rotatably arranged on the support plate. A filter material box is arranged at the top of the rotating cylinder, filter material is filled inside the filter material box, and a feeding port is arranged at the bottom of the filter material box;

[0017] The shaft rod is rotatably and sealingly connected to the side wall of the condensation shell, and one end of the shaft rod passes through the condensation shell and is fixedly connected to the center of the gear;

[0018] The surface of the rotary drum is provided with grooves for carrying the filtering material, and the rotary drum is rotationally and sealingly connected to the discharge opening of the filtering material box; a guiding pipeline is arranged on the supporting plate on one side of the bottom of the rotary drum, and the outlets of the condensation pipeline and the guiding pipeline are both located directly above the purification chamber. An electric control valve is arranged at the bottom end of the guiding pipeline.

[0019] Description: The impeller drives the gear to rotate, so that the rotary drum carrying the filtering material at the groove rotates. Through the filtering material box and the guiding pipeline, intermittent and uniform feeding is carried out to avoid too fast pouring of the filtering material, and continuous small amount of feeding can be realized, so that new filtering material can be continuously added to the cavity of the purification pool that is not discharging liquid or discharging material, improving the adsorption utilization rate of the filtering material and avoiding the gradual weakening of the adsorption effect with the increase of the use times and time in the conventional purification treatment after adding the filtering material at one time; when the purification pool rotates, the feeding is suspended through the electric control valve at the discharge opening at the bottom of the filtering material box, and when the purification pool is stationary, continuous feeding is resumed.

[0020] Further, gel-type resins for adsorbing impurities in glycerol are placed inside the purification chamber; a filter plate for preventing the filtering material and the gel-type resins from falling is arranged above the first electric control valve, and a filter net for preventing the gel-type resins from falling but allowing the filtering material to pass through is arranged above the second electric control valve, and the particle size of the filtering material is smaller than that of the gel-type resins.

[0021] Description: Gel-type resins for adsorbing impurities in glycerol are placed inside the purification chamber, which helps to improve the purification efficiency of glycerol. The gel-type resins can effectively adsorb and remove impurities in glycerol, such as metal ions, pigments, etc., so as to improve the purity and quality of glycerol; the filter plate is used to prevent the filtering material from falling when glycerol is discharged, and the filter net is used to prevent the gel-type resins from falling when replacing the bottom-layer filtering material.

[0022] The beneficial effects of the present utility model are as follows: The present utility model synthesizes glycerol through a hydrolysis reaction kettle, and then the produced crude glycerol is directly introduced into a distillation kettle through a pipeline for high-efficiency distillation. The glycerol droplets discharged by distillation enter a condensation pipe assembly through a pipeline for condensation, and after being converted into a liquid state, they flow into a purification assembly for purification. The liquid glycerol is received by a purification pool, and filtration and adsorption are carried out in the purification pool. The cavity of the purification pool is switched by the rotation of a motor, and a contact sensor is used to detect and judge whether the internal of the cavity of the purification pool meets the liquid discharge requirement, and the adsorbed and purified glycerol product is discharged. Then, the filtering material that is added first and used multiple times is removed, and the replacement of the filtering material is automatically controlled, which is simple and convenient. Discharging the liquid first and then the filtering material avoids waste of glycerol; realizing integrated production, through automatic control, reducing the intermediate links of production and purification, reducing manual intervention, and improving production efficiency.

The small glycerol droplets discharged from the distillation are condensed through the pipeline into the condenser assembly 3 and converted into a liquid state and then flow into the purification component 4 for purification. The liquid glycerol is received by the purification tank 41, and filtration and adsorption are carried out in the purification tank 41. The cavity of the purification tank 41 is switched by the rotation of the motor, and the contact sensor is used to detect and judge whether the internal of the cavity of the purification tank 41 meets the liquid discharge requirement, and the adsorbed and purified glycerol product is discharged. When the purification tank 41 rotates, the cavity originally receiving the liquid glycerol rotates above the liquid-carrying cavity 43 where liquid needs to be discharged. When rotating, the electronic valve at the liquid outlet of the condensation pipeline 31 is closed, and when stationary, the electronic valve is opened. After the purified cavity rotates to the connection position with the liquid-carrying cavity 43, the contact sensor 45 detects the position and opens the first electric control valve for liquid discharge. By the time the next cavity is purified, the liquid discharge has already ended. The purification tank 41 continues to rotate. After the target cavity passes above the contact sensor 4550 times in the contaminated material cavity 44, the second electric control valve is opened for a limited time to discharge the bottom filter material; due to the continuous feeding of the feeding module 46, the filter material is naturally replaced to avoid accumulation and improve the purification effect.

[0053] Embodiment 4

[0054] The difference between this embodiment and Embodiment 1 is that the refrigeration medium uses a refrigeration gas, the pump body is an air pump, and both the refrigeration gas and the air pump are commercially available products.
