RU172129U1 - DEVICE FOR CLEANING WATER FROM IRON COMPOUNDS - Google Patents

Abstract

The utility model is intended for highly efficient purification of groundwater from compounds of iron and other harmful impurities. This is achieved by the fact that the device is made in the form of a water-air ejector, including an internal nozzle in the form of a truncated cone of direct-flow feed water and an external pipe that creates an annular chamber with holes for air intake, which passes further into the mixer and into the turbulization chamber of the water-air flow, with the installation of a separator with a filter nozzle, a perforated chipper and ultraviolet electric lamp (not conventionally shown).

Description

The inventive utility model is designed for highly efficient groundwater purification from iron compounds and other harmful impurities.

It is known that when artesian water containing ferrous iron is contacted with air oxygen, iron oxidizes to ferric iron with a precipitation of hydroxide.

A device for purifying water from iron compounds is known (patent for PM No. 117426), containing a mixer with two water-air ejectors with opposing flow directions, a separator with a chipper to separate gas from liquid and a filter for purifying water from suspended particles (1).

With all the positive qualities of the effective operation of the device, it should be noted the high cost of its manufacture.

The technical result of the proposed device is a significant reduction in manufacturing costs due to the simplification of its design.

This is achieved by the fact that the device is made in the form of a water-air ejector, including an internal nozzle in the form of a truncated cone of a straight-through supply of source water and an external pipe that creates an annular chamber with holes for air intake, which passes further into the mixer and into the chamber for turbulization of the air-water stream and the high efficiency of groundwater purification from iron compounds and other harmful impurities is achieved by installing a separator with a filter nozzle, a perforated chipper and, if necessary, ultraviolet commercial lamp (not conventionally shown in the drawing).

In FIG. 1 shows a general view of the device; in FIG. 2 shows a sectional view of a water-air ejector.

The device consists of a water-air ejector 1, a separator 2 with a filter nozzle 3 and a perforated chipper 4 for separating the gas-water mixture.

A water-air ejector consists of a nozzle 5 in the form of a truncated cone of a straight-through supply of source water, an external nozzle 6 with an annular chamber 7 with openings 8 for air intake, which then passes into the mixer 9 and into the turbulization chamber 10 of the air-water stream.
