Energy-saving preheating structure of molecular distillation equipment

Abstract

The invention discloses an energy-saving preheating structure of molecular distillation equipment, and relates to the technical field of molecular distillation equipment. The structure further comprises an outer shell, a heat conduction mechanism and a heat preservation mechanism. The outer shell sleeves the outer side of a heavy component buffer tank; first sealing rings are fixed to the inner ring walls of the upper side and the lower side of the outer shell correspondingly. The inner ring walls of the first sealing rings on the upper and lower sides are fixedly connected with the outer sidewalls of the upper and lower sides of the heavy component buffer tank respectively; a heat conduction mechanism is arranged in the outer shell; the inner side wall of the outer shell is in contact with a preheating feeding pipe, one end of the preheating feeding pipe penetrates through one side wall of the outer shell and then is connected with a connecting pipe, the other end of the connecting pipe is connected with molecular distillation equipment, the other end of the preheating feeding pipe penetrates through the other side wall of the outer shell and then is suspended on the outer side of the outer shell, and a heat preservation mechanism is arranged on the outer side of the connecting pipe; heat on the heavy component buffer tank can be quickly transferred to the feeding pipe, the heat energy collecting and recycling effect is improved, and the structure has the advantages of being reasonable in arrangement, low in manufacturing cost and the like.

Problems solved by technology

[0002] Molecular distillation, also known as short-path distillation, is a relatively new liquid-liquid separation technology that has not been widely used in industrial production. Its application can solve a large number of problems that cannot be solved by conventional distillation technology. A complete set of molecular distillation equipment mainly includes : Molecular evaporator, degassing system, feeding system, heating system, cooling vacuum system and control system, etc. The molecular distillation equipment is connected to the feed pipe and the heavy component buffer tank, and the feed pipe is connected to the feed system of the molecular distillation equipment. For molecular distillation equipment feeding, the feeding tube is wound on the outer surface of the heavy component buffer tank, so that the heat in the heavy component components of the molecular distillation equipment can preheat the feed of the dispersed molecular distillation equipment, to a certain extent The problem of heat energy waste is solved, but the feed pipe is directly wound on the heavy component buffer tank and is in contact with the outer surface of the heavy component buffer tank. The heat transfer efficiency between the heavy component buffer tank and the feed pipe is low, and the heat energy is collected again Unsatisfactory use, need to improve
