Description

Technical Field

[0001] The utility model relates to the technical field of biodiesel, in particular to continuous transesterification equipment for biodiesel. Background Art

[0002] Biodiesel refers to fatty acid methyl or ethyl esters formed by converting vegetable oils (such as rapeseed, soybean, peanut, corn, and cottonseed oils), animal oils (such as fish, lard, beef tallow, and mutton fat), waste oils, or microbial oils with methanol or ethanol through esterification. Biodiesel is a quintessential "green energy" offering excellent environmental performance, strong engine starting performance, superior fuel quality, and a broad and renewable raw material supply. The vigorous development of biodiesel is of strategic importance for sustainable economic development, promoting energy substitution, alleviating environmental pressures, and controlling urban air pollution.

[0003] In the biodiesel production process, transesterification is an important process. The transesterification reaction consists of a series of reversible reactions. Triglycerides are converted into diglycerides, monoglycerides, and finally into glycerol and fatty esters. Although each step of the reaction is reversible, the reaction balance generally proceeds in a direction that is conducive to the production of fatty acid methyl esters and glycerol.

[0004] The continuous transesterification device for producing biodiesel disclosed in Chinese utility model patent application publication number CN216808742U improves the level of process automation control through continuous feeding and discharging, ensures production safety, improves product quality stability, increases equipment utilization and production efficiency, and reduces labor intensity. However, the existing equipment cannot load materials quickly and conveniently, cannot prevent precipitation generated during loading, cannot continuously carry out biodiesel transesterification production, cannot recycle methanol, pollutes the environment, causes harm to the health of workers, and the purity of the obtained biodiesel is not high. The equipment cannot be cleaned, which reduces the service life of the equipment, affects the quality and efficiency of biodiesel, and may pose a safety hazard. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0016] In summary, the technical effects and advantages of the utility model are:

[0017] 1. The utility model has a reasonable structure. Raw materials, methanol and catalyst are added respectively through the feed pipe on the upper surface of the feeding box, and the raw materials, methanol and catalyst are simply filtered through the filter plate. The feeding stirring shaft is driven by the rotary motor to rotate, and stirring is carried out in the feeding box to prevent precipitation. The fan is rotated to make the raw materials, methanol and catalyst in the feeding box enter the main cylinder along the feeding pipe, reducing the inconvenience of fast and convenient feeding of the equipment, wasting working time, and failing to simply filter the raw materials, methanol and catalyst. There will be particles, and it is inconvenient to quickly replace the filter plate. Therefore, fast feeding can be carried out through the feeding component, which prevents the raw materials, methanol and catalyst from precipitating in the feeding box and reducing the purity rate. The mixing motor drives the main stirring shaft to rotate, stirs the mixed raw materials in the main cylinder, heats the mixed raw materials in the main cylinder through the heating ring on the outer surface of the main cylinder, and makes the mixed raw materials in the main cylinder react. The raw materials after the reaction in the main cylinder enter the main sedimentation tank through the docking pipe on one side of the main sedimentation tank for precipitation and cooling. Since the glycerol after the reaction is insoluble in biodiesel and the density of glycerol is greater than that of biodiesel, it will settle to the bottom of the tank and be discharged through the oil outlet pipe at the bottom of the main sedimentation tank. The raw materials after the reaction in the main sedimentation tank enter the auxiliary cylinder through the docking pipe on the side of the auxiliary cylinder, and the auxiliary stirring motor inside the auxiliary cylinder cover drives the auxiliary stirring shaft to rotate, stirs the raw materials that have reacted in the auxiliary cylinder, and heats the raw materials that have reacted in the auxiliary cylinder again through the heating ring on the outside of the auxiliary cylinder.

[0018] 2. In the utility model, the biodiesel after the second reaction is allowed to enter the flash tank through the docking tube on one side of the flash tank, water is introduced through the water inlet pipe on one side of the flash tank, and the flash tank is turned into a vacuum state by an air pump for reaction. After observing the pressure gauge, the methanol is allowed to flow into the collection barrel along the air channel through the exhaust pipe on the upper surface of the flash cover, and water is introduced through the water inlet pipe on the upper surface of the collecting cover. The methanol in the collection barrel is cooled along the pipeline inside the collection barrel, and then water is discharged through the water outlet pipe provided on the upper surface of the collecting cover. The methanol in the collection barrel is discharged through the discharge pipe on the side of the collection barrel, which reduces the waste of resources, increases the reaction cost, wastes manpower and material resources, damages the surrounding environment, and causes harm to the health of the staff, thereby improving resource utilization by recycling the methanol. The utilization rate is high, the production cost is reduced, and the economic benefits are increased. The biodiesel enters the auxiliary sedimentation tank through the docking pipe on one side of the auxiliary sedimentation tank, the glycerin is discharged by unscrewing the separation plug, and the biodiesel enters the discharge barrel for collection through the discharge pipe on the side of the discharge barrel. After collection, the cleaning agent is added to the cleaning tank through the water inlet pipe on the upper surface of the cleaning cover, and the cleaning agent is sprayed from the water outlet on the lower surface of the high-pressure nozzle through the water pump on the lower surface of the cleaning tank to clean the auxiliary sedimentation tank, thereby reducing the amount of biodiesel residue after the reaction in the auxiliary sedimentation tank that is inconvenient to clean, affecting the quality of biodiesel generated by continuous reaction, low production efficiency, and possible safety hazards. Therefore, the auxiliary sedimentation tank is cleaned by the cleaning component, which extends the service life of the equipment and improves the quality and efficiency of the product.

The pipe allows the reacted raw materials in the main cylinder 1 to enter the main sedimentation tank 6 for precipitation and cooling. Because the reacted glycerol is insoluble in biodiesel, the density of glycerol is greater than that of biodiesel, so it will settle to the bottom of the tank and be discharged through the oil outlet pipe at the bottom of the main sedimentation tank 6. The reacted raw materials in the main sedimentation tank 6 enter the auxiliary cylinder 7 through the butt joint on one side of the auxiliary cylinder 7. The auxiliary stirring motor 9 inside the auxiliary cylinder cover 8 drives the auxiliary stirring shaft 10 to rotate, and stirs the reacted raw materials in the auxiliary cylinder 7.

Water enters through the water pipe, and the flash tank 11 is turned into a vacuum state through the air pump 13 for reaction. After observing the pressure gauge, the methanol is allowed to flow into the collection barrel 16 along the air channel 14 through the exhaust pipe on the upper surface of the flash cover 12, and water is introduced through the water inlet pipe on the upper surface of the collecting cover 15. The methanol in the collection barrel 16 is cooled along the pipeline inside the collection barrel 16, and then water is discharged through the water outlet pipe provided on the upper surface of the collecting cover 15. The methanol in the collection barrel 16 is discharged through the discharge pipe on one side of the collection barrel 16, which reduces resource waste, increases reaction costs, wastes manpower and material resources, damages the surrounding environment, and causes harm to the workers. Therefore, by recycling methanol, resource utilization is improved and production costs are reduced. The economic benefits are increased. The biodiesel enters the auxiliary sedimentation tank 17 through the docking tube on one side of the auxiliary sedimentation tank 17, the glycerol is discharged by unscrewing the separation plug 18, and the biodiesel enters the discharge barrel 19 through the discharge pipe on one side of the discharge barrel 19 for collection.

The production efficiency is not high and there may be safety hazards.
