DETAILED DESCRIPTION - Natural energy sea water desalting and sewage purifying device comprises a filtering pool, a preheating pool, a spray evaporating chamber, a steam condensing device and a fresh water pool which are mutually communicated via pipelines and form a natural energy sea water desalting and sewage purifying device together with a heat conductive oil heating pipe, a natural energy heat conductive oil heating pipe, a solar cell set and a wind power generator. The filtering pool is connected to the preheating pool via a pipeline. The top of the preheating pool is equipped with a solar plating coating glass. The heat conductive oil heating pipe and the pressurizing water pump are mounted in the pool and are communicated with the spray evaporating chamber via a pipeline. An atomizing sprayer is mounted on the pressure pipeline in the spray evaporating chamber. The heat conductive oil heating pipe is mounted in the chamber. One side of the spray evaporating chamber is equipped with a discharge port capable of opening and closing. The top of the spray evaporating chamber is equipped with a steam collecting chamber connected to the steam condensing device via a steam pipeline. The steam condensing device is equipped with a micro refrigerating condensing device. The lower end of the steam condensing device is equipped with a condensed water collecting port connected with a fresh water pool via a pipeline. The tail end of the steam condensing device is an exhaust port with an exhaust fan. The preheating pool and the heat conductive oil heating device mounted in the spray evaporating chamber are connected to the natural energy heat conductive oil heating device via a heat conductive oil pipeline. A heat conductive oil circulating oil pump with a separated machine and pump is mounted on the heat conductive oil pipeline. Heat conductive oil is injected, and an electric heating pipe is mounted in the natural energy heat conductive oil heating device, and the electric heating pipe is electrically connected to the solar cell set and wind power generator via leads.
