Compact and cleanable apparatus for preventing scale formation in liquid systems

摘要

A device for eliminating mineral precipitation within a liquid system. A container having inlet and outlet pipes is connectable to external plumbing to receive and pass through the container untreated water or liquid. The inlet pipe is connected within the container to a fitting having a treatment pipe extending therebeneath to the bottom of the container. A metal treatment bar is suspendedly positioned within the treatment pipe, but is spaced internally therefrom to allow the untreated water to contact and pass over the treatment bar eventually emptying into the container. The water exiting the treatment pipe eventually exits the container through the outlet pipe. The treatment bar is fixedly and suspendedly mounted by a rod extending out of the container and secured to a plug sealingly, but removably mounted to the container top wall. The plug is removable along with rod and treatment bar to facilitate cleaning of the bar. A pressure relief valve is mounted to the container top wall to allow for manual release of pressure. Valves are provided on the inlet and outlet pipes in conjunction with a by-pass valve extending therebetween to prevent flow of liquid to the container when the treatment bar is removed for cleaning.
