APPARATUS FOR DISSOLUTION OF CARBON DIOXIDE FOR WATER TREATMENT

摘要

An apparatus for dissolution of carbon dioxide for water treatment is provided to produce carbonated water by mixing dissolution water with carbon dioxide more efficiently, and perform water treatment operation more efficiently by injecting the carbonated water into water flown into a water purification plant or a sewage/wastewater treatment plant of water supply and drainage facilities. An apparatus for dissolution of carbon dioxide for water treatment comprises: a carbon dioxide supplying pipeline(100) including a carbon dioxide tank(110), vaporizers(120), and flow meters(140); a dissolution water supplying pipeline(200) including a dissolution water pump(210); an injection member(300); and a dissolution device member(400). The dissolution device member includes: a first mixing part in which dissolution water and carbon dioxide mixed by the injection member pass through a porous variable orifice valve(410); a second mixing part in which dissolution water and carbon dioxide mixed through the first mixing part pass through in-line mixers(420) having a spiral rotation part; and a pipe(430) in which carbonated water(dissolution water and carbon dioxide) mixed through the second mixing part remains for a relatively long time.
