▎ 摘　　要

NOVELTY - Reverse blowing device includes a filter ceramic pipe connected from an air compressor (4) to an inlet of one-way air valve (5). An air pipe is connected from a top of an air storage tank (6) is connected to an entrance of an electromagnetic gas valve (7). A gas pipe connected to the main vapor pipe from the electromagnetic air valve is connected with a gas pipe. A steam pipe connected with one way steam valve (9) from a boiler (8). A top of a steam tank (10) is equipped with a steam pressure relay. A top portion of the steam tank is provided with an air pressure relay from the top of the air tank. The gas pipe is connected with the main vapor tube (11) from an electromagnetic steam valve. The pipeline connecting from the main gas tube and the shell are connected to the shell of the seawater desalting membrane core. USE - Reverse blowing device for a reverse osmosis sea water desalting film core used for producing drinking water for domestic use. ADVANTAGE - The reverse blow-through device of reverse osmosis sea water desalination membrane core is capable of efficiently and economically desalinating the sea water with high purity and reduced energy consumption thus providing the desalinated water with reduced size and weight. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a control method of reverse osmosis device for reverse osmosis seawater desalination membrane core. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the reverse blowing device for a reverse osmosis sea water desalting film core used for producing drinking water for domestic use.
