Suspending-membrane aeration type same-chamber membrane distillation device capable of increasing water yield

The invention provides a suspending-membrane aeration type same-chamber membrane distillation device capable of increasing water yield. The suspending-membrane aeration type same-chamber membrane distillation device comprises a high-molecular insulating material layer, a box body, a steam collecting pipe, wire-type membranes (or plate-type membranes or drum-type membranes), flanges, loose joints, releasers, an air distributing water pipe, a concentrated water outlet pipe, water steam outlet pipes and a hot water inlet pipe, wherein the hydrophobic membranes (which can be the wire-type membranes, the plate-type membranes or the drum-type membranes) are connected with the steam collecting pipe made from high-molecular materials and are communicated with peripheral steam pipes by the loose joints and the flanges. The suspending-membrane aeration type same-chamber membrane distillation device provided by the invention can be used in a suspending-membrane aeration type same-chamber membrane distillation system; in a whole membrane distillation process, the evaporation capacity is increased by taking measures of enlarging contact surface area, increasing air flow speed, reducing pressure and the like, and thus the water yield is increased; and concentrated water is discharged or flows back to a hot water tank from the concentrated water outlet pipe of the suspending-membrane aeration type same-chamber membrane distillation device, so that concentrated liquid is not contacted with a distillation membrane, therefore, no membrane pollution is caused, and further, the phenomenon that precipitated crystals scratche the distillation membrane can be avoided.
