COOLING TURBINE |
摘要 |
FIELD: cooling equipment. SUBSTANCE: centrifugal compressors and inward-flow turbines are arranged in cooling turbine in pairs. Their blades are positioned on common discs and have covering screens. Discs have circular protrusions over periphery and are placed along axis in sequence. Covering screens are extended and closed over periphery of circular protrusion of disc. In addition screens carry ribs. Holes are made in circular protrusion of each disc in its periphery under point of linking of screens. Centrifugal compressor of first stage has across inlet to it intake apparatus in the form of system of inward-flow rotary compression diffusers with intake holes over periphery of rotor. Inward-flow turbine of last stage has across outlet discharge apparatus in the form of system of centrifugal rotary expansion confusers with outlets over periphery of rotor. Holes for inlet of cooled cycle air are made in body above intake holes of diffusers. Holes for outlet of cooled cycle air are made above outlets of confusers. Tubes to feed cooling air from atmosphere to screens and tubes to remove heated cooling air from screens are located in spaces between covering screens. Reflecting screen is placed in front of discharge apparatus. EFFECT: reduced mass and dimensions , enhanced operational efficiency of cooling turbine. 5 dwg
