4.2 Design and function
4.2.1 Design of a vacuum chlorinator
Fig. 4-1: Design of a vacuum chlorinator
The chlorine gas is under overpressure when it comes from the chlorine
barrels. The vacuum regulator (
1
) only allows the chlorine to flow if
there is a suctioning vacuum at the device’s output. Therefore, if a line
behind the vacuum regulator breaks, there is no need to fear a chlorine
leak.
The dosing device comprises a flow meter (
2
) with manual control
valve, and also often an electrically actuated control valve (
3
) and a
pressure regulator (
4
).
The injector (
6
) creates the vacuum based on the Venturi effect and
mixes the chlorine gas in the motive water flow. If the water does not
move, chlorination is stopped immediately. Then the non-return valve
(
5
) prevents water from penetrating into the dosing devices.
