Description

June 28, 1960 c, LYLE ETAL SEALING MEANS FOR ROTARY REGENERATIVE HEAT EXCHANGER Filed larch 5, 1957 therethrou gh with opposite ends of said regenerative mass being disposed in parallel planes lying normal to the of the rotor adapted to direct a low pressure fluid therethrough; second. inlet andflo'utlet ducts at opposite ends of the rotor lying eccentric to the rotor axis adapted to direct; a'highpressure fluid through that portion of the f rotor'lying' therebetween; and sealing shoes surrounding the second inlet andtoutlet ducts'bearing frictionally 7 against opposed surfaces of said'rotor to isolate the high pressure fiuid from the remainder of the matrix, said sealing shoes including'concentrically' disposed annular grooves in the face thereof contacting the rotor whereby high pressure fluid'entrained in the matrix betweensealing shoes beyond the second duct is direct to the matrix between sealing shoes in advance of said duct.
2. Heat exchange apparatus including a rotor containing amass of regenerative heat exchange material 'rotor axis; first inlet and outlet ducts at opposite ends adapted todirect a second fluid-through the portion of therotor therebetween; sealing shoes encircling the second inlet and outlet ducts having plane facesbiased into sealing relationship with the end faces of the regenerative mass to preclude fluid flow between the first and second ducts, said seal-ing shoes having concentric annular defining 'a multiplicity of axially disposed passageways 7 extending therethrough with the opposite ends of said regenerative mass being disposed in parallel, planes lying normal to the rotor axis; first inlet and outlet ducts at oppositeends of the rotor adapted to direct a first fluid therethrough; second inlet and outlet ducts at opposite ends of r the rotor positioned eccentrically to the rotor axis to direct the flow of a second fluid through a portion of the rotor therebetween; sealing shoes encircling the second inlet and outlet ducts 'heid in sealing relation with the second inlet and ,outlet ducts and confronting the :the' regenerative-mass to preclude leakage 'of fluid bea i t tween thefirst and' second ducts, said sealing shoes having endless groove means in the surface thereof encircling Q 7 end faces of said regenerative mass adapted to provide a 7 7 labyrinth sealing effect and simultaneously afford flow V passageways for the flow of fluid between 'arcuately spaced grooves in the plane faces thereof (confronting axially opposite end faces of said regenerative 'mass adapted to provide a labyrinth sealing effect and simultaneously afiord flow passageways permitting How of fluid between portions of the regenerative mass intermediate theisealing shoes.
