Description

Technical Field

[0001] The utility model relates to the technical field of hydrogenated rosin production equipment, in particular to an oil-water separator used for the production of hydrogenated rosin glycerol ester. Background Art

[0002] Rosin undergoes hydrogenation to generate hydrogenated rosin, and hydrogenated rosin undergoes esterification with glycerol to obtain hydrogenated rosin glycerol ester. Compared with rosin, hydrogenated rosin has higher antioxidant properties, does not change color when oxidized in air and light, has no tendency to crystallize, is less brittle, has strong adhesion, and can maintain elasticity for a long time.

[0003] During the esterification reaction of hydrogenated rosin and glycerol, the esterification reaction is a reversible reaction. Only by continuously removing water during the esterification reaction can the quality of the esterification reaction be ensured. At the same time, during the esterification reaction, hydrogenated rosin and glycerol need to be mixed and heated. If the heating intensity is not enough, the esterification reaction will be slow, and the water produced by the esterification reaction will not be completely discharged, making the esterification reaction incomplete. If the heating intensity is sufficient, the unreacted glycerol will be entrained in the reflux exhaust gas, resulting in a waste of glycerol. And the discharged glycerol may contain water, resulting in a low purity of glycerol, which is not conducive to the recovery or recycling of glycerol.

[0004] Therefore, the utility model provides an oil-water separator for the production of hydrogenated rosin glycerol ester to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 to Figure 2 As shown, the utility model provides an oil-water separator for the production of hydrogenated rosin glycerol ester, comprising a base 1, an esterification kettle 2 is arranged on the base 1, a controller 3 is arranged on the base 1, a through pipe 1 4 is connected to the top of the esterification kettle 2, a recovery tank 5 is threadedly installed at one end of the through pipe 1 4, a heater 6 is arranged on the side wall of the recovery tank 5, a through pipe 2 7 is threadedly installed on the top of the recovery tank 5, a condenser 8 is connected to one end of the through pipe 2 7, an inlet pipe 9 and an outlet pipe 10 are arranged on the side wall of the condenser 8, the inlet pipe 9 and the outlet pipe 10 are respectively connected to a pump 11, one end of the condenser 8 is connected to a through pipe 3 12, and one end of the through pipe 3 12 is connected to a collecting tank 13.

[0020] Since glycerol is miscible with water, and the boiling points of glycerol and water are different, the boiling point of water is 100°C, and the boiling point of glycerol is about 290°C, therefore, by distilling the discharged glycerol and evaporating the water, the glycerol and water can be separated, thereby obtaining pure glycerol without water.

[0021] The heater 6 is an electromagnetic heating ring, which is sleeved on the outside of the recovery tank 5 and is used to heat the recovery tank 5. A connecting rod 14 is provided at one end of the electromagnetic heating ring and is fixedly installed on the side wall of the esterification kettle 2 through the connecting rod 14. The electromagnetic heating ring is electrically connected to the controller 3, and the through-tube controller 3 controls the heating of the electromagnetic heating ring.

[0022] Sleeves 16 are provided at both ends of the connecting pipe 15. In order to ensure the reliability of glycerin separation, threads are provided on the side walls of through pipe 1 4, through pipe 2 7 and through pipe 3 12. Threads are provided on the side walls of both ends of the connection, and threads are provided on the inner side wall of the sleeve 16. The sleeve 16 can be detachably connected to the connecting pipe 15 through threads. At the same time, the connecting pipe 15 is threadedly and sealedly connected to through pipe 1 4, through pipe 2 7 or through pipe 3 12 through the sleeve 16, thereby ensuring a stable connection and a sealing effect, so that the water can be fully distilled, and the pure glycerin separation effect is achieved, so that the separated glycerin can be recycled.

[0023] Furthermore, the connecting tube 15 is an internally hollow conduit or an internally solid plugging tube. When in use, the internally hollow conduit is first installed on the through pipe 14 to achieve communication with the recovery tank 5, so as to facilitate the storage of the glycerin containing water; when it is necessary to start heating and separating the glycerin, the internally solid plugging tube is installed on the through pipe 14 to cut off the communication between the through pipe 14 and the recovery tank 5, thereby ensuring a sealed space and facilitating the distillation work.

[0024] Working principle: when the unreacted glycerin is removed from the reflux exhaust gas, the glycerin will enter the recovery tank 5 through the through pipe 4 and be collected. When it is necessary to start heating and separating the glycerin, a solid plugging pipe is installed on the through pipe 4 to cut off the connection between the through pipe 4 and the recovery tank 5. At this time, the controller 3 starts to control the heating of the electromagnetic heating ring, so that the glycerin and water mixture inside the recovery tank 5 begins to boil gradually. When the temperature rises to 100°C, the water is evaporated into water vapor and enters the condenser 8. The pump 11 starts to work and pumps cold water from the water inlet pipe 9 and out of the water outlet pipe 10, so as to realize the condensation of water vapor in this cycle. Finally, the condensed water vapor becomes water droplets and falls into the collection box for collection. At this time, what is left in the recovery tank 5 is pure glycerin without water. When it is necessary to collect the pure glycerin, the recovery tank 5 can be taken out by screwing out the connecting pipe 15 installed on the through pipe 1 4 and the through pipe 2 7. The detachable connecting pipe 15 not only improves the convenience of use, but also ensures the sealing during distillation, so that the water can be fully evaporated, and the pure glycerin can be separated, so that the separated glycerin can be recycled.

[0025] In summary, the utility model provides an oil-water separator for the production of hydrogenated rosin glycerol ester, which realizes the distillation separation of glycerol and water by setting a recovery tank 5 and performing efficient electromagnetic heating of the recovery tank 5 by the electromagnetic heating ring and the condensation action of the condenser 8; at the same time, the detachable connecting pipe 15 not only improves the convenience of use, but also ensures the sealing during distillation, so that the water can be fully evaporated, and the pure glycerol separation effect is achieved, so that the separated glycerol can be recycled.
