Pentaerythritol, which belongs to polyhydric alcohol organic matters, is white crystal or powder, is combustible, and is a key raw material for producing high-solid-content, water-soluble and general alkyd resin, rosin ester, synthetic lubricating oil and antioxidant; with the continuous improvement of the production process of pentaerythritol, the quality and the yield of the product are greatly improved, but the recovery of pentaerythritol mother liquor not only involves the problem of environmental protection, but also contains considerable amounts of sodium formate and pentaerythritol with industrial value. At present, in the existing mother liquor recovery treatment process, the mother liquor is enriched and viscous in the concentration process, pentaerythritol crystals are difficult to separate from the mother liquor, a large amount of pentaerythritol is not effectively recovered, the recovery rates of pentaerythritol and calcium formate are low, the product quality is general, the organic matter content in the treated waste liquor is high, and the problem of serious three wastes still exists.
Solvent extraction is commonly adopted in developed western countries to recover mother liquor, and the extracting agent is often isobutanol, tetrahydrofuran, cyclohexanone, tert-butanol and the like. The solvent extraction method is used for treating pentaerythritol mother liquor, a large amount of organic solvent is needed, if the solvent is not recycled, higher production cost is increased, the organic solvent is easy to pollute the environment, and the existing solvent recovery equipment is complex, has higher investment and is not suitable for large-scale use.
Therefore, a pentaerythritol solvent recovery tower was designed to solve the above problems.

Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
Please refer to fig. 1. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship which the products of the present invention are usually placed in when used, which is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
