METHOD FOR CLEANING INNER SURFACE OF HEATING RADIATORS OF HEAT- AND WATER MAINS INSIDE BUILDINGS AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2003 - IPC

FIELD: surface cleaning equipment, namely for cleaning inner and outer surfaces of heat exchange or heat transfer ducts of heat and water mains of central heating systems of many-storied and one-story buildings and erections. SUBSTANCE: method comprises steps of disconnecting radiators from heating system; filling them with water at providing air cushion and creating hydraulic shocks; providing zones for hydraulic shocks and forming hydraulic shocks with use of compressed air in lower portion of each section of radiator in two directions to side of vertical cavities; trapping water-air liquid containing fractured deposits through upper portion of radiator; then separating liquid from deposits and returning it to lower portion of cooling tower; successively supplying compressed air pulses from previous section to next one; inspecting hydraulic shock zones under vertical cavities of each section. Apparatus for performing the method includes base for mounting radiator, pipelines, compressor. It is also includes receiver connected through pipelines with compressor and through air T-shaped tube - with hose; silencer in the form of reservoir with mounting pipes; supporting base for air tube; movable coordinate dial. Reservoir is secured to heating radiator through its upper and lower nipple openings. Mounting pipes are mutually communicated. Bottom of reservoir is arranged at lower level of air curtain in radiator. Air tube has two openings in its lower end; said openings are inclined one relative to another by 90 degrees. Air tube may be moved through lower opening of radiator and mounting pipe of silencer and fixed. EFFECT: enhanced efficiency, improved technological process of cleaning surfaces. 2 cl, 2 dwg
