Product Description

Product Description

General Information

Membrane distillation module is a module for membrane distillation, which is a thermally driven transport process that uses hydrophobic PTFE hollow fiber membrane.
Membrane distillation module is made of high-performance hydrophobic hollow fiber membranes in membrane distillation technology of sweeping gas membrane distillation.
The working principle of membrane distillation module:
First, the feed liquid is heated to a certain temperature by using factory waste heat or steam, and then pumped into the membrane distillation module through the raw material pump. Membrane distillation modules are potted with hollow fiber microporous hydrophobic PTFE membranes, which have a large number of micropore. At high temperatures, the feed liquid generates a vapor pressure difference on two sides of the membrane. A large number of micropore can allow the evaporated water vapor to pass through the membrane pores, enter the other side of the membrane hollow fibers, and use the vacuum system to pump it out. After a large amount of water vapor volatilizes, the feed liquid is concentrated. The volatilized steam uses the heat pump to recover heat and returns to reheat the feed liquid to reduce the energy consumption of the entire system.

Notice:
1. When the liquid temperature is 85°C, the safe internal and external pressure difference of the membrane hollow fibers should be less than 0.08 MPa, and the maximum pressure difference should not be greater than 0.1 MPa.
2. When used for the concentration of different materials, the feed liquid shouldn't contain organic solvents such as alcohols, esters, hydrocarbons, ethers, oils, etc., otherwise the service life of hollow fibers will be shorter and leakage may happen.
3. A certain flow rate is required when the feed liquid flow over the outer surface of the membrane hollow fibers. Please adjust the flow rate according to the actual conditions such as the viscosity, temperature, and crystallinity of particles of the feed liquid to prevent crystallization or high surface concentration of the membrane hollow fibers from evaporation decrease.
