DISTRIBUTED DESALINATION SYSTEM BY MIXING SOLAR THERMAL AND PYROLYSIS GASIFICATION ENERGY

摘要

The present invention relates to a distributed seawater desalination system using solar thermal energy with waste heat energy. The system comprises: a solar heat supplying device supplying hot water as a first heat source; a waste heat supplying device supplying steam as a second heat source; a first branched part connected between the solar heat supplying device and the waste heat supplying device and selectively supplying the first heat source or the second heat source to one end of a heat source pipe; a multi-effect evaporative seawater desalination device receiving the first heat source or the second heat source from the heat source pipe and carrying out a seawater desalination process; a second branched part connected to the other end of the heat source pipe arranged in the multi-effect evaporative seawater desalination device and supplying the first heat source or the second heat source used in the seawater desalination process to the solar heat supplying device or the waste heat supplying device; and a control unit controlling the operation of the first branched part and the second branched part. The control unit selectively supplies the first heat source or the second heat source to the multi-effect evaporative seawater desalination device by controlling the operation of the first branched part and resupplies the first heat source and the second heat source used in the seawater desalination process to the solar heat supplying device and the waste heat supplying device respectively by controlling the operation of the second branched part.
