PLANT FOR DEIRONIZING OF UNDERGROUND WATER IN STRATUM Russian patent published in 1996 - IPC

FIELD: water supply engineering. SUBSTANCE: plant includes ejector, deaeration chamber with air escape valve, well head connected to the chamber through connecting pipeline. Chamber is provided with upright barriers arranged along chamber length and fastened to its bottom. The barriers' height gradually decreases in the direction of stream travel. Between barriers, additional upright barriers are mounted in such a way that they divide chamber along its length into a series of inlet and drain sections. In the former, additionally mounted are upright plates attached to cap, their free lower parts being twisted in a common direction at angle not less than 180 deg and their twisting lengths being equal to the length of submerged part of additional barrier in the last section in series. With well pump switched off, water is forced to nozzle of water-air ejector. Air-saturated stream is directed into the inlet section of chamber having highest upright barrier. When stream in the 1st inlet section goes up, it partially releases air. Further, stream enters the 1st drain section and therefrom the 2nd inlet section. In ensuing sections the same deaeration takes place which is promoted by stream twisting caused by the above mentioned twisted plates in inlet sections. Released air is conveyed through air escape valve into atmosphere. EFFECT: achieved deaeration of underground water. 1 dwg
