The utility model provides cleaning agent recovery equipment with a multi-stage distillation purification function, which relates to the technical field of cleaning agent recovery and comprises a first-stage distillation tower, a condenser arranged at the top of the first-stage distillation tower, a feed port arranged at the top of the first-stage distillation tower, a connecting pipe arranged on one side of the condenser, a steam channel arranged on one side of a thermal insulation layer, and a second-stage distillation tower arranged on the other side of the thermal insulation layer. The second-stage distillation tower is arranged on one side of the first-stage distillation tower, the third-stage distillation tower is arranged on one side of the first-stage distillation tower, the feeding pipe is arranged on one side of the third-stage distillation tower, and the first-stage distillation tower, the second-stage distillation tower and the third-stage distillation tower are used in turn, so that a cleaning agent can be distilled and purified for multiple times; impurities and dirt in the cleaning agent are effectively removed, and the purity of the recycled cleaning agent is improved. Compared with single-stage distillation equipment, the multi-stage distillation equipment disclosed by the utility model can meet the use scene with a higher purity requirement, the application range of the recovered cleaning agent is expanded, and meanwhile, the multi-stage distillation towers are used in turn, so that the cleaning agent can be distilled and purified for multiple times.

This invention discloses a prefabricated concrete pavement panel connection structure and construction method. With the development of prefabricated building technology, the application of prefabricated concrete pavement panels in road engineering is becoming increasingly widespread. In this invention, the upper and lower dovetail interlocking steel plates are identical in shape, forming a dovetail shape composed of two symmetrically arranged isosceles trapezoids. After the prefabricated concrete pavement panels one and two are spliced, an upper interlocking groove is formed on the top surface, and a lower interlocking groove is formed on the bottom surface. The upper interlocking steel plate is embedded in the upper interlocking groove; the lower dovetail interlocking steel plate is embedded in the lower dovetail interlocking groove; the upper and lower dovetail interlocking steel plates, and the prefabricated concrete pavement panels one and two are connected by steel plate fasteners; the sides of the prefabricated concrete pavement panels one and two are provided with tongue and groove joints; the tongue and groove joints on the concrete pavement panels one and two are spliced ​​to form grouting grooves; grouting holes are provided on the upper and lower interlocking steel plates. This invention achieves efficient transfer of horizontal and vertical loads on the pavement panels, improves the overall integrity and durability of the structure, and has high construction efficiency.

The application discloses a hydrophilic convertible ternary eutectic solvent and a preparation method and application thereof, and belongs to the technical field of plant active substance extraction. The hydrophilic convertible ternary eutectic solvent is prepared by taking tetrabutylammonium chloride, dichloroacetic acid and ethylene glycol as raw materials. The eutectic solvent can be used as an extraction reagent to extract polyphenol components in sorghum bran. Compared with traditional extraction reagents, 70% ethanol and 70% methanol, the ternary eutectic solvent greatly improves the yield of polyphenols in sorghum bran.
