Relationship condensation dehumidifying and drying

From the process can be achieved using the nitrogen cycle, nitrogen is the key to the whole system of dehumidification. If dehumidification is not good enough nitrogen will affect the recovery of the solvent content of the organic solvent will increase, reach the drying requirements, easily lead to the emergence of production risks and other issues, we can see condensation dehumidifying part is key to the whole system link.

From condensation dehumidifying and drying relations, with the lower nitrogen content of ethanol, the dew point temperature of the mixed gas is also reduced, which is the lower amount because the total pressure constant containing ethanol saturated conditions the partial pressure of steam in the steam decreases, the dew point temperature will be reduced.

Look at the whole process of dehumidification equipment system, when a lower dew point temperature of the gas drier, and subsequent condensation of dehumidification operating costs will increase, in order to achieve the corresponding dew point temperature; when exposed process is more difficult to achieve temperature points to reach the following 9 ℃ water condensed gases, and a corresponding increase in the cost of operations, so that the moisture content of the gas after the drier the better.

Obtain a higher moisture content of the dryer select from a smaller amount of gas is very important, if the vibration fluidized bed dryer, vibration fluidized import will reduce the rate at smaller gas velocity reached fluidized state, the smallest decrease in the flow of gas can reduce the required amount of gas velocity, thereby reducing dust entrainment other supporting machines from the specification can be made small, reduce costs, improve energy efficiency; also through exciting Force heat transfer, mass transfer process, improve the moisture content of other small wind conditions. So that when the low temperature nitrogen gas to dry the materials needed for effective dehumidification, moisture can reach 0.02 to 0.09%. Control of moisture content can also be automated remote control, the whole process is carried out in a closed environment, it can also monitor the whole process of adjustment parameters to improve production efficiency.
