Problems solved by technology

In the same production process, it is necessary to change the cooling and heating media multiple times, which will easily lead to mixed pollution of different cooling and heating media. On the one hand, it will affect the temperature control efficiency, and on the other hand, the cost of cooling and heating media after pollution will be high.
[0003] For the related technologies mentioned above, the inventor believes that there is a shortcoming that it is difficult to adapt to large-scale industrial applications

Embodiment Construction

[0034] The following is attached Figure 1-2 The application is described in further detail.

[0035] The reaction kettle is a common reaction device 7 in the field of medicine and chemical industry, including a reaction kettle body 71 and a reaction kettle jacket 72. The reaction kettle jacket 72 is set on the outside of the reaction kettle body 71, and the inside of the reaction kettle jacket 72 is arranged along the circumference of the reaction kettle. There is a temperature control pipeline, the liquid inlet of the temperature control pipeline is arranged at the bottom of the reaction kettle jacket 72, and extends out of the reaction kettle jacket 72, and the liquid outlet of the temperature control pipeline is arranged at the top of the reaction kettle jacket 72, And stretch out reactor jacket 72 and set. When in use, by connecting the temperature control pipeline with the heating system and the cooling system, the heating medium or cooling medium is delivered to the te...

Abstract

The invention relates to a single-medium heating and cooling system in the field of temperature control equipment. The single-medium heating and cooling system comprises a heating unit, a refrigerating unit, an expansion box, a heat transfer medium storage box and a heat transfer medium pump. The heating unit, the refrigerating unit, the heat transfer medium storage tank and the heat transfer medium pump are connected in series through pipes and are used for regulating the temperature of a reaction device. The heating unit and the refrigerating unit are continuously arranged in the transmission direction of a heat transfer medium; and the expansion box communicates with the pipe through a first connecting pipe and is used for buffering the volume change of the heat transfer medium. The single-medium heating and cooling system has the effect of being suitable for large-scale industrial application.

Description

technical field [0001] The present application relates to the field of temperature control equipment, in particular to a single-medium heating and cooling system. Background technique [0002] In the reaction process in the chemical and pharmaceutical fields, it is often necessary to perform intermittent heating and cooling operations in different production stages in the same reaction equipment. The existing reaction equipment often uses a multi-media temperature control system for temperature adjustment, that is, using water vapor Heating by means of electric heating or heat medium; cooling by cooling water or refrigerated brine circulation. In the same production process, it is necessary to change the cooling and heating media multiple times, which will easily lead to mixed pollution of different cooling and heating media. On the one hand, it will affect the temperature control efficiency, and on the other hand, the cost of processing the contaminated cooling and heating ...
