RU2750460C1 - Water-pressure storage tank for water with increased radon content - Google Patents

Abstract

FIELD: public utilities.

SUBSTANCE: invention relates to public utilities and can be used for water supply to settlements from wells with a high content of radon in the water. The technical result is achieved due to the fact that in a water-pressure storage tank, covered with a dome, having ventilation windows in its upper and lower parts, containing a branch pipe for parsing water from the lower zone of the tank and in the center a vertical riser for supplying water to the upper zone of the tank, having in in the lower part, the hole is closed by a valve under the action of a stream of water flowing through the riser, and an ejector is installed in the upper part at the outlet of the water diffuser, on the riser in front of the water diffuser at a height above the maximum possible water level in the tank. A decrease in the concentration of radon occurs due to the installation of an ejector in the flow of water entering the tank, which promotes the formation of a water-air emulsion at the inlet to the tank.

EFFECT: increasing efficiency of water purification from radon contained in it.

Description

The invention relates to public utilities and can be used for water supply to settlements from wells with a high content of radon in the water.

Known water storage tank [1], taken as a prototype, in which the removal of radon from the water coming from the well is carried out by gushing water under a dome covering the tank. However, it sometimes does not achieve the removal of radon to the permissible concentration, especially with a high content of radon in the source water.

The purpose of the present invention is to eliminate this disadvantage.

The technical result is achieved due to the fact that in a water-pressure storage tank, covered with a dome, having ventilation windows in its upper and lower parts, containing a branch pipe for parsing water from the lower zone of the tank and in the center a vertical riser for supplying water to the upper zone of the tank, having in in the lower part, the opening is closed by a valve under the action of a stream of water flowing through the riser, and an ejector is installed in the upper part at the outlet of the water diffuser, on the riser in front of the water diffuser at a height above the maximum possible water level in the tank.

The essence of the invention is illustrated by the drawing shown in FIG. one.

The water tower according to the invention has a pressure storage tank 1, in the lower part of which there is a draw-off pipe 2 and a riser 3 running in the center of the container, connected through a pipe 4 with a pump installed in the well (not shown in the drawing). In the lower part of the riser there is a hole 5 with a diameter of 2 ... 3 mm for draining water from the riser in case of shutdown of the pump and complete emptying of the tank.

The tank is covered with a dome 6, comparable to it in volume, having ventilation windows 7 in the lower part and a ventilation window 8 in the center in the upper part 8. A valve 9 is installed at the inlet of opening 5, which is triggered by the flow of water flowing through the riser 3, at the outlet of which a diffuser 10 is installed in front of the diffuser in the direction of water movement on the riser an ejector 11 is installed.

The water tower works as follows.

When the pump is turned on, the flow of water rushing through the ejector 11 sucks in air bubbles through the inlet openings of the ejector, forming a water-air emulsion at the outlet of the ejector. The reduced pressure in the narrow part of the ejector and the large contact area of air and water bubbles contribute to the intensification of radon emission from it. Further, passing through the diffuser 10, water is sprayed in the volume of the dome 6. In this case, the radon remaining in it after the ejector is released from the water, which, together with the air, leaves through the ventilation windows 7 and 8 into the atmosphere. At the same time, under the action of the water flow, the valve 9 closes the opening 5, thereby preventing water with a high radon content from entering the container through the opening 5.

In the event of an emergency shutdown of the pump, for example, when a pipeline breaks or there is no voltage in the electrical network supplying the pump, the water level in the tank will drop. The water level in the riser will also decrease (water from the riser will leave through hole 5, which will prevent the riser from freezing in the winter season.

Thus, the radon content in the water coming from the artesian well, when used in this water-pressure storage tank, the ejector will be significantly lower.
