Description

Technical Field

[0001] The utility model relates to the technical field of glycerol production, in particular to a desalination device for glycerol production. Background Art

[0002] Glycerin is widely used in various fields such as textiles, daily consumer goods, and the rubber industry. Therefore, the market demand for glycerin is very large and its manufacturing companies are developing rapidly.

[0003] The production of glycerol requires a purification process: crude glycerol is distilled and processed to obtain refined glycerol. However, a large amount of sediment will remain in the purification process of crude glycerol. The sediment contains a large amount of salt and other impurities, which is the glycerol residue. When salt and other impurities are precipitated at the bottom of the distillation pool, long-term accumulation will occupy the volume of the distillation pool and affect the output of refined glycerol purification.

[0004] The existing method to solve the problem of residual glycerin residue after glycerin purification is mostly to manually clean the distillation pool at regular intervals to remove the glycerin residue. This cleaning method is not only inefficient, but also labor-intensive, which seriously affects the processing output. In addition, the crude glycerin is often heated unevenly after distillation, so that the yield of refined glycerin produced by processing cannot meet people's expectations, which is inconvenient to use. Utility Model Content

[0005] The utility model aims to provide a desalting device for glycerol production, which is designed to improve the cleaning efficiency of desalting and other impurities during glycerol production and processing, reduce the intensity of manual cleaning, effectively improve processing efficiency, and help improve processing output and yield.

[0006] To achieve the above object, the utility model provides a desalination device for glycerol production, comprising a distillation tank and a sealing cover, wherein the sealing cover is fixedly connected to the distillation tank and is located on the top of the distillation tank, and further comprises an auxiliary component;

[0007] The auxiliary components include a feed pipe, a spiral roller, a filter, a cleaning pipe, a cleaning valve, a discharge valve, a driving member and a discharge member.

[0008] Wherein, the driving component includes a support column and a power component, the support column is fixedly connected to the sealing cover and is located on the top of the sealing cover; the power component is arranged on one side of the support column.

During processing, crude glycerin is transported into the distillation pool through the feeding pipe, and after being filtered through the filtering net, enters the upper cavity of the distillation pool. Then, the distillation pool is heated by operating to increase the internal temperature. When the glycerin inside the distillation pool reaches the boiling point and starts to evaporate, the driving component drives the spiral roller to rotate, drives the crude glycerin to continuously move inside the distillation pool, accelerates the evaporation speed of the glycerin, and the evaporated glycerin flows out through the discharge component and is collected to become refined glycerin.
