CHEMICAL WATER TREATMENT SYSTEM Russian patent published in 2024 - IPC F17D3/12 C02F1/68 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and can be used in water treatment systems for dosing reagents in boiler houses and heat stations. In the chemical water treatment system on the main pipeline there is a pump, on the inlet side of which a suction pipeline is connected, and behind the pump there is a bypass pipeline, on which two valves controlled by the moment of opening/closing are installed in series, operating in an alternating mode, wherein the output of the second controlled valve is connected to the drain line, and between the controlled valves a branch pipe is connected, which connects the bypass pipeline to the drive chamber of the membrane proportioner, in the dosing chamber there are holes connecting the dosing chamber with a channel between the inlet and outlet valves, and a return spring is installed in the drive or dosing chamber.

EFFECT: simplification and improvement of reliability of water treatment system with possibility of its use in small-size boiler houses.
