History of distillation technology
In ancient Greece, there were records of people using the principle of distillation to purify seawater into drinking water. In China, the use of distillation to make wine has a reliable history of thousands of years.
Since solvents are volatile, waste solvents contain various impurities such as paint, resin, and curing agent, so the use of distillation to purify solvents came into being. Solvent recovery equipment was first introduced from abroad and has become mature in China after decades of development. As various industries in China are under pressure to save costs and protect the environment, the market is gradually expanding.
Solvent recovery equipment
The solvent recovery equipment independently developed by our company is mainly composed of a heating system, a condensation system, a Chinese and English electronic control system, a pressure control system, oil temperature and steam temperature thermocouples, a stainless steel double-layer barrel and heat transfer oil, a fuselage frame, etc. The whole machine adopts an explosion-proof structure design, and all electronic control components are explosion-proof structures, including the electric control box, motor, heater, oil temperature sensor, steam sensor, etc.
The equipment uses the principle of heating distillation, and the heat transfer oil is indirectly transferred to the solvent, so that the solvent vaporizes and enters the condensation device, and the clean solvent is recovered to achieve the purpose of solvent recycling. At the same time, the volume of residual hazardous waste after recycling is greatly reduced, and the cost of hazardous waste disposal is also reduced accordingly.
