Vacuum Type Gas Chlorination Plant

Vacuum Type Gas Chlorination Plant represents the latest advance in the design of solution (vacuum) feed gas chlorination. It incorporates many technological advances designed to enhance long-term reliability and achieve optimum performance with minimum supervision and maintenance. The chlorine regulator can be mounted either on a wall or on top of the gas cylinder or container. Correct operation depends on obtaining healthy vacuum from the ejector. Water flowing through the ejector creates a vacuum, which opens the inlet valve to admit the gas into the regulator. The ejector consists of a vacuum producing venturi and a spring-loaded diaphragm check valve. The gas passes through the flow meter and the rate control valve, and then to ejector where it is thoroughly mixed and dissolved in the water and carried to the application point as a solution. Any vacuum failure automatically shuts off the supply of chlorine gas and ensures that no gas escapes into the atmosphere. There is an automatic vent to atmosphere if pressure builds up in the regulator. If the source of chlorine gas is exhausted or the gas line plugged, the excess vacuum valve in the regulator closes to prevent any moisture being pulled back into the regulator or the gas supply lines. AQUA II gas chlorinator and ejector are constructed from PVC, VICTOM, monel, Teflon, and extra- duty borosilicate glass, silver and copper materials.
