AN APPARATUS FOR THE PRODUCTION OF DRINKING WATER AND INDUSTRIAL QUALITY WATER USING RENEWABLE ENERGY SOURCES AND ITS METHOD THEREOF

摘要

The present invention discusses the method for continuous production of clean and pure clean and pure drinking water and industrial quality water by utilizing the raw feed liquid drawn either from the surface of the sea or condenser rejected waste water from process plants including power plants, or any other heat sources that have minimum temperature gradient of at least 4.5° C with respect to condensation water temperature, where in an apparatus is used for creating and maintaining a low pressure using an external device. The raw feed liquid with most of the non-condensable gases removed passes through an evaporation chamber and ejects through a plate consisting of multiple holes with or without projections to form a thin film of water layer to enhance the generation of the vapor. A filter is provided to avoid seawater droplet entrainment along with the vapour before entering into the inclined condensation chamber. The vapour changes its phase to liquid using the ambient seawater or deep sea told water that flows through the tube bundles which is housed inside the inclined condensation chamber and placed below the evaporation chamber. The remaining un-evaporated liquid in the bottom of the evaporation chamber is continuously discharged by gravity without using any pumping aid at near ambient temperature and without much increase in salinity concentration to the sea. The quantity of condensed water is also based on the flow rate and temperature difference between the feed liquid and the water used for condensation. The product water is continuously monitored for its quality by a quality meter, which diverts the product water back to the feed liquid if the quality of the product water falls below the required limits of the user. The generated water is pumped to the storage tank and can be used for multiple purposes including drinking water, boiler quality requirements and other user requirements.
