AVTOMATICHESKOE DOZIROVANIE REAGENTOV IN SYSTEMS OF VODOSNABZHENIYA I KOTEL'NYKH
Most municipal boiler rooms are used for the feed of caldrons «unboiled» water without some pre-treatment. On this account the layer of deposit of salts appears on the midwalls of pipes, that results in the decline of tekhniko-ekonomicheskikh indexes of work of caldrons, their death. The high level of otlozhe-niy salts arises up and on the internal surfaces of teploobmennikov of hot vodosnab-zhe-niya of thermal points during their work without the periodic washings. A method and device (on the last a patent is got) is offered dosages of reagent, providing stopping of appearance of new salt deposits and gradual removal of old deposits. Development foresees permanent control after pressure in a pipeline, in which a dosage, and also limitation of maximal time, is produced between the input of next doses of reagent.70
