NOVELTY - The utility model claims a low energy consumption membrane distillation system, comprising a feeding tank, a water producing tank; a hollow fibre membrane group; the feeding tank is connected with the hollow fibre membrane group through the feeding pipeline; the water producing tank is connected with the hollow fibre membrane group through the water producing pipeline; the hollow fibre membrane group is further provided with a reflux pipeline connected with the feeding tank; the hollow fibre membrane group comprises a hollow fibre membrane; the hollow fibre film is composed of a hydrophobic micro-porous film layer and a graphene conductive layer; the hydrophobic micro-porous film layer is located on the material liquid side; the graphene conductive layer is located on the water producing side; the feeding pipeline is provided with a gas disturbance component. The utility model is added with the disturbance component for air disturbance; at the same time, the hollow fibre film adopts composite structure; the graphene conductive layer is heated by current; the water inlet amount of the material liquid side film assembly is small; the material liquid circulation speed is slow; the heating energy consumption is low; it realizes the reduction of the concentration polarization phenomenon; improving the use stability of the membrane distillation system, at the same time, reducing the energy consumption of the membrane distillation system.
