Prospects for the use of magnetic inserts in slurry mixers

The energy intensity of Ukraine's GDP exceeds the analogous indicator of the European Union countries more than 3 times. One of the main factors of this situation is the inefficient use of fuel, one of the largest consumers of which is heat power, including communal. The reasons for the inefficient use of fuel cells in centralized heat supply systems of Ukrainian cities lie in the wear and tear of the equipment of these systems. Chemical water treatment systems are no exception. Due to their unsatisfactory state, processes of corrosion in the system elements are accelerated and the amount of deposits in them increases. The presence of deposits on surfaces significantly influences the thermodynamic efficiency, reliability and life of heat-exchange equipment. Accelerating processes of scale formation and increasing the number of complex deposits leads to the need for a more frequent rinsing of the system, which leads to contamination of network water with mechanical impurities, which, in turn, accelerates the abrasive wear of heating surfaces and the emergence of other problems in the work of systems. These negative factors condition the need to improve the quality of cleaning of network water from mechanical blockages. One of the methods of intensive purification of network water from mechanical cravings may be the introduction of magnets into the composition of standard sludge absorbers, which is associated with a large number of iron oxides in the composition of contaminants. Iron oxides actively react to the magnetic field, and in addition there is to some extent coagulants, which accelerates the purification of network water and from magnetonase-related mechanical impurities. The mechanism of water purification from mechanical impurities after flushing of boilers and other heat-energy equipment is considered. The results of the experimental study of prospects for the use of magnetic inserts in slurry mixers are presented.
