Description

The invention relates to the disinfection of water, in particular, can be used to supply chlorine gas to the treated water.

The purpose of the invention is to increase the reliability of operation by preventing water from entering the gas supply line, and gas into the water supply line from the water main to the glass vessel.

The drawing shows an apparatus for dosing chlorine gas, a general view,

The apparatus consists of a filter 1, a pressure gauge 2, an adjusting valve 3, a rotameter 4, a glass vessel 5 in which a reflector 6 is placed in the form of a hollow cylinder located above the outlet tube 7 for chlorine coaxially last, and an overflow tube 8. On the upper glass cover A vessel 5 is fitted with a shut-off valve 9, and on the bottom lid there is an inlet fitting 10 for water, on which a check valve 11 is mounted. A chlorine outlet tube 7 is connected to ejector 12. A shut-off valve 13 is installed in front of the chlorine gas metering device.

The device is also equipped with a water line 14, a water supply line 15 and a gas supply line 16.

Chlorine dosing is carried out as follows.

Through the gas supply line 16, through the filter 1 and the adjusting valve 3, the chlorine enters the rotameter 4, and then through the valve 9 into the glass vessel 5 into which water is supplied from the water line 14 through the water supply line 15, the inlet fitting 10 and the check valve 11. . From the glass vessel 5, chlorine mixed with water through the outlet tube 7 enters the ejector 12, where it is additionally mixed with water from the water line 14.

When the water supply to the ejector 12 is abruptly stopped, water from the water line 14 due to the vacuum generated in the device passes through the outlet tube 7 into the reflector 6 and fills the glass vessel 5, being set at a certain level due to the gas plug formed. At the same time, part of the water through the overflow tube 8 is brought into

ventilated waste tray (not shown). The flow of gas into the water supply line 15 and the water line 14 is prevented by a check valve 11.

The reflector b does not allow water to flow from the outlet tube 7 into the gas supply line 16.

The invention allows to increase the service life of the apparatus.
