A mobile water source type temperature-controllable pharmaceutical reaction device

Abstract

The invention relates to a pharmaceutical reaction device, in particular to a flowing water source type pharmaceutical reaction device with controllable temperature. A flowing water source type temperature-controllable pharmaceutical reaction device includes a pharmaceutical reaction kettle, a first phase-change heat exchanger, a second phase-change heat exchanger, an electronic expansion valve, a four-way reversing valve and a frequency conversion compressor. Under cooling / heating working conditions, the second phase-change heat exchanger continuously releases / absorbs heat into the water tank, and judges where to use the flowing water with heat / cooling capacity according to the water temperature detected by the third / fourth temperature sensor. This process not only improves the corresponding cooling / heating efficiency of the first phase-change heat exchanger to the drug reaction kettle, but also the flowing water in the used water tank from the high-temperature / low-temperature outlet pipe can be recycled according to actual needs. Different process links of pharmaceutical manufacturing, such as sterilization and preheating links or cooling and precooling links, realize energy cascade utilization, energy saving and environmental protection.

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
