Indirect-type heat-cycle evaporation system

Abstract

The invention discloses an indirect-type heat-cycle evaporation system. The indirect-type heat-cycle evaporation system comprises a material-liquid pot, an evaporating chamber, a material-liquid heater, a heat-water heater, a condenser, a separator and a compressor; the material-liquid pot is communicated with the evaporating chamber, the bottom of the material-liquid heater is connected with theevaporating chamber, the material-liquid heater siphons material liquid from the evaporating chamber, the heat-water heater and the condenser are connected with the compressor, and a refrigerant in the compressor absorbs heat by the condenser and conveys the heat to the heat-water heater; the heat-water heater comprises another heating medium, the heating medium absorbs the heat of the refrigerant, the heating medium is introduced into the material-liquid heater for heating the material liquid, and the temperature of the heating medium of the heat-water heater is constant while flows out; thecondenser is connected with the separator, and the separator is connected with a vacuum pump and a condensate pump. The flammable and explosive organic solvents used for a pharmaceutical company are subjected to evaporative concentration, compared with organic solvent condensation equipment for the traditional pharmaceutical company, the indirect-type heat-cycle evaporation system has the advantages of energy saving, environmental protection, high solvent recovery rate, safety and reliability, stable operation, and simple operation.

Description

technical field [0001] The invention relates to an evaporation system, in particular to an indirect heat cycle evaporation system. Background technique [0002] Energy conservation and environmental protection have become the development direction of all mankind. At present, in my country's pharmaceutical industry, how pharmaceutical companies reduce operating costs, reduce drug production costs, and enhance product market competitiveness has become the primary goal and is also related to the long-term development of the enterprise. At present, pharmaceutical factories mainly use traditional single-effect concentrator equipment for the evaporation and concentration of flammable and explosive organic solvents, which consumes a lot of energy and has a high solvent loss rate. How to develop an evaporation system with low energy consumption, the ability to concentrate flammable and explosive solutions, high solvent recovery rate, safety, reliability, and stable operation is par...

AI Technical Summary

Problems solved by technology

The existing single-effect MVR evaporation device can solve the problems of traditional steam as heat source, long evaporation residence time, low concentration ratio, high evaporation energy consumption and high cost, but if single-effect evaporation and concentration containing flammable and explosive solvents For the MVR evaporator, there will be unsafe factors due to the contact between the flammable and explosive solvent vapor and the high-speed compressor impeller.
