HOUSING OF TURBO-COMPRESSOR MAINLY USED FOR COMPRESSION OF HYDROGEN-SULFIDE GASES Russian patent published in 2001 - IPC

FIELD: chemical engineering. SUBSTANCE: turbo- compressor housing includes support and cylindrical shell with inlet and outlet branch pipes provided with gas inlet and outlet passages. Inner surface of inlet branch pipe at gas inlet is formed by conical oval cylindrical adapter engageable with passage of inner surface of truncated obelisk having oval at branch pipe gas outlet. Assumed vertical of truncated conical section of adapter and obelisk are directed towards each other. Inner surface of passage of outlet branch pipe is formed at outlet by oval cylindrical conical adapter engageable with oval cylindrical conical adapter at branch pipe gas outlet. Assumed vortex of conical surface is directed inside housing. At branch pipe inlet and outlet surfaces of passages of oval cylindrical adapters are formed by upper and lower cylindrical section which are located in parallel with longitudinal axis of branch pipe at inlet of inlet branch pipe and lie at angle to longitudinal axis at outlet of inlet branch pipe. Cylindrical sections are located at angle relative to longitudinal axis at inlet of outlet branch pipe and in parallel with this axis at outlet branch pipe. EFFECT: enhanced operational efficiency; reduced level of noise and vibration. 5 cl, 10 dwg
