TUBE CLEANING DEVICE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; oil industry; construction engineering. SUBSTANCE: proposed device is provided with gas-turbine engine, compressor bleed-off branch pipes with flexible hoses connected with air receiver which is connected in its turn with module for injection of water into air through inlet shut-off adjusting fittings. Located between air receiver and water injection unit is module for measuring air flow rate which is connected with air receiver by means of metal-reinforced hose. Air receiver is provided with adjustable dampers at its inlet and with its own frame. Proposed device excludes overheating of engine, thus increasing time of continuous operation and reducing thermal stresses in structural members maintaining required temperature of vapor-and-air mixture. EFFECT: enhanced efficiency and reliability. 3 cl, 1 dwg
