AN INTEGRATED DEVICE FOR CLEANING OF THE CYCLE AIR OF A GAS TURBINE INSTALLATION Russian patent published in 2005 - IPC

FIELD: production of gas-purifying devices.

SUBSTANCE: the invention is dealt with a integrated air-cleaning devices and may be used for clearing of air taken from atmosphere and its preparation for feeding in a compressor of a gas turbine installation to protect the vane elements against an abrasive wear. A technical problem of the invention is provision of a high degree of clearing of the cycle air at an inlet of in a compressor of a gas turbine installation (GTI), and also maintenance of a high reliability and a serviceability in operation. The problem is solved due to installation in the intake inlet chamber of an additional air-cleaning device made in the form of a polyhedral multitier prismatic framework with a capability of rotation around an axis passing through centers of its bases and coaxial with the axis of rotation of the gas turbine installation. At that on each of lateral faces of the framework within the limits of tier there are cells with hermetically installed in them the air-cleaning elements. Mounting of an additional device of an air cleaning allows to reduce essentially dimensions of the air intake chambers and to reduce action of wind loadings on elements of structures of the installations and the foundations.

EFFECT: the invention ensures essential reduction of the air intake chambers dimensions and wind loadings on the elements of the structures of the installations and their foundations.
