FIELD: heating systems.
SUBSTANCE: device for preparing make-up water for a heat supply system consists of incoming water pipe connected to a decarbonator, decarbonated and deaerated water pipes connected to a deaerator, acid carrying pipe with a flow-control pump connected to the incoming water pipe, and alkali carrying pipe with a flow-control pump connected to it. The alkali carrying pipe is connected to the deaerated water pipe. The device is equipped with a regulator of the given pH, connected to a pH sensor for the incoming water after the connection point of the acid carrying pipe to the pH sensor of the deaerated water after connection of the alkali carrying pipe, as well as a device for regulating frequency of rotation of the control pumps of acid and alkali.
EFFECT: increased quality and economy of preparing make-up water due to more accurate regulation of the doses of acid and alkali in the make-up water.
