The principle and application characteristics of vacuum depressurization and concentration tank
Date: 2025-02-18Read: 18
A vacuum depressurization concentration tank is a device that uses a negative pressure pump to draw the concentrated substance into a vacuum tank, and performs process operations such as heating, evaporation, condensation, shrinkage, and exhaust under vacuum or low pressure.
Firstly, put the substance that needs to be concentrated into the concentration tank, then close the valve through the pressure reducing system, start the vacuum pump to evacuate, and reduce the pressure inside the tank to a certain value.
Next, start the heater to heat the concentrated substance. When the temperature of the concentrated object rises to a certain level, the liquid begins to evaporate, and the vapor becomes liquid after being cooled by the condenser. This process is repeated continuously in the concentration tank, and the concentrated object gradually concentrates. The solvent of the concentrated object is continuously recycled and discharged after the solid is concentrated.
Finally, when the concentration of the concentrate reaches the required level, stop heating and disconnect the vacuum pump. At this point, the tank will re-enter the atmosphere, the valve will be opened, and the concentrated material will be extracted and subjected to subsequent processing.
The vacuum depressurization and concentration tank equipment has the following application characteristics:
1. High concentration efficiency: The vacuum depressurization concentration tank equipment has a high concentration efficiency, usually able to concentrate substances to around 99% or 9% at low temperatures.
2. Workplace safety: The vacuum depressurization concentration tank equipment operates at low temperatures, and the air inside the concentration tank is treated to meet safety standards, ensuring the safety of the working environment.
3. Easy to operate: The vacuum depressurization and concentration tank equipment has the characteristics of high intelligence and simple operation, making it convenient for practical use.
4. Energy saving: The vacuum depressurization concentration tank equipment has the characteristic of concentration at low temperatures, which can effectively save energy costs. At the same time, valuable solvents in the concentrated material can be recycled and reused, avoiding cost waste.
