DEVICE FOR WATER PURIFICATION AND NEUTRALIZATION OF DEPOSIT IN BOILERS AND PLATE-TYPE HEAT EXCHANGERS Russian patent published in 2004 - IPC

FIELD: purification of water and prevention of deposit formation in boilers and plate-type heat exchangers. SUBSTANCE: invention presents a device used for a water purification, in particular for purification of water from impurities suspended in it and for prevention of deposit formation in boilers and plate-type heat exchangers. The device has units of water purification and deposit neutralization, that are mounted in a body with branch-pipes of water supply and water export. The unit of water purification contains the device of the water swirling and the device of impurities settling. The unit of deposit neutralization is made as an ensemble of piezoceramic rings and plates. EFFECT: the device allows to lower acidity of water and, as a result of it, to slow oxidation of the pipelines in the boilers and plate-type heat exchangers, to decrease a factor of friction of water and to prevent formation of salt deposits-sediments-adjournments in the pipelines. 6 cl, 2 dwg, 1 tbl
