Multi-energy energy-saving distillation kettle

Abstract

The invention discloses a multi-energy energy-saving distillation kettle. The multi-energy energy-saving distillation kettle comprises a kettle cover, a kettle body and a kettle bottom, wherein solar heat absorption devices are arranged on the outer parts of both the kettle cover and the kettle body; a stirring device which extends into the kettle body is also mounted at the central position of the kettle cover; an electric heating rod is placed in the stirring device; a hot water inlet and an exhaust port are also formed in the kettle cover; the hot water inlet is connected with a cold water outlet through a heat exchange coil pipe wound in the kettle body. According to the multi-energy energy-saving distillation kettle, an outer material is heated by external solar energy, an intermediate material is heated by the heat exchange coil pipe, a core material is heated by the electric heating rod, and the material is stirred by the stirring device, so that over-high local temperature of the material is avoided; the material is heated more uniformly; the distillation effect is better.

Description

technical field [0001] The invention relates to a still, in particular to a multi-energy and energy-saving still. Background technique [0002] Distillation is a commonly used method for separating and purifying liquid mixtures, and can also determine the boiling point of liquid compounds, so it has certain significance for identifying pure liquid compounds. The distillation process requires heating, which consumes a lot of heat and energy. At present, solar energy technology has not been used in the distillation operation. Conversion equipment does not meet the corresponding requirements. [0003] In addition, since the distillation still is used under high temperature and high vacuum, usually in order to maintain its high vacuum, the still adopts an integral structure. However, with the development of the coal chemical industry, more and more coal chemical industries have begun to Use crude oil real boiling point distillation equipment to evaluate the properties of c...

Problems solved by technology

[0003] In addition, since the distillation still is used under high temperature and high vacuum, usually in order to maintain its high vacuum, the still adopts an integral structure. However, with the development of the coal chemical industry, more and more coal chemical industries have begun to Use crude oil real boiling point distillation equipment to evaluate the properties of coal tar, coal liquefied oil, etc. Sometimes it is necessary to evaluate the properties of residues and asphalt left in the kettle. If the above distillation kettle is still used, the samples cannot be completely taken out of the kettle. , will affect the evaluation of sample performance
