Автоматическое дозирование реагентов в системах водоснабжения и котельных

Abstract

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 otlozheniy salts arises up and on the internal surfaces of teploobmennikov of hot vodosnabzheniya 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
