Abstract
The present disclosure to an apparatus for membrane distillation using a solar absorber and a heat pump, in which in the implementation of a membrane distillation process for producing treated water using a temperature difference between raw water and a coolant, raw water is heated using the solar absorber with improved heat collection efficiency, and through this, the treated water production efficiency of the membrane distillation process is improved.
Claims17
An apparatus for membrane distillation using a solar absorber and a heat pump, comprising:
- a raw water circulation pipe that circulates raw water in a raw water tank;
- a solar heat absorbing device provided on one side of the raw water circulation pipe to heat the raw water in the raw water circulation pipe;
- a raw water tank that receives the raw water heated by the solar heat absorbing device through the raw water circulation pipe and supplies the raw water to a membrane distillation module;
- the membrane distillation module that produces treated water from the raw water through a membrane distillation process;
- a coolant tank that supplies a coolant to the membrane distillation module and collects the treated water produced by the membrane distillation module;
- and
- the heat pump that heats the raw water and cools down the coolant when a temperature difference between the raw water in the raw water tank and the coolant in the coolant tank is smaller than a reference value.
