Flowing water source type temperature-controllable pharmaceutical reaction device

Abstract

The invention relates to a pharmaceutical reaction device, particularly to a flowing water source type temperature-controllable pharmaceutical reaction device, which comprises a medicine reaction kettle, a first phase-change heat exchanger, a second phase-change heat exchanger, an electronic expansion valve, a four-way reversing valve and an inverter compressor. According to the invention, under the working condition of refrigeration / heating, the second phase-change heat exchanger continuously releases / absorbs heat into the water tank, the position where flowing water with heat / cold is used isjudged according to the water temperature detected by the third temperature sensor and the fourth temperature sensor, and in the process, the efficiency that the first phase-change heat exchanger provides corresponding cold / heat for the medicine reaction kettle is improved, flowing water from the high-temperature / low-temperature water outlet pipe in the used water tank can be recycled in different process links such as a sterilization preheating link or a cooling precooling link and the like for medicine manufacturing according to actual requirements, gradient utilization of energy is achieved, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to a pharmaceutical reaction device, in particular to a flowing water source type pharmaceutical reaction device with controllable temperature. Background technique [0002] Pharmaceutical processes often involve reactions such as dissolution, emulsification, and catalysis. These reactions are often accompanied by a large number of endothermic or exothermic processes. During the reaction process, it is necessary to provide corresponding cooling or heat to ensure the temperature requirements of the reaction process. [0003] In conventional equipment, high-grade electric energy is directly converted into heat energy to obtain high or low temperature, resulting in a large amount of waste of high-grade energy. There are also some devices that use an air source heat pump system to obtain cooling or heat. Under severe weather conditions, the cooling or heating efficiency is low, and under heating conditions, the outdoor evaporator (sec...

[0003] In conventional equipment, high-grade electric energy is directly converted into heat energy to obtain high or low temperature, resulting in a large amount of waste of high-grade energy

There are also some devices that use an air source heat pump system to obtain cooling or heat. Under severe weather conditions, the cooling or heating efficiency is low, and under heating conditions, the outdoor evaporator (second phase changer) is prone to frosting conditions. Terminal equipment is required to defrost, and air is used as a heat transfer medium, which has low heat transfer efficiency and low energy efficiency of the system
