Gas turbine guide vane device and gas turbine

Abstract

The invention provides a gas turbine guide vane device and a gas turbine. The gas turbine guide vane device comprises a first shell and a second shell which are separately provided with a first surface and a second surface which are oppositely arranged, at least one first guide vane structure, at least one first guide vane shaft and at least one active driving mechanism; the first guide vane structure is arranged between the first surface and the second surface and comprises a first end part and a second end part; the first guide vane shaft is connected to the first end part; a first hole which corresponds to the first guide vane shaft is formed in the first shell; the first active driving mechanism is arranged on the side, which is far away from the first surface, of the first shell; andthe first guide vane shaft penetrates through the first hole and is connected to the active driving mechanism. According to the gas turbine guide vane device, the guide vane structure can be driven toswing by the driving mechanism; the control on the area of the fluid passing cross section of a fluid passage is realized through rotation of the guide vane structure, and finally control on the airinlet amount is realized; the guide vane structure is adjustable radially; the structure of the device is simple and reasonable; and the air inlet flowing amount of an air inlet passage can be effectively adjusted.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, in particular to a gas turbine guide vane device and a gas turbine. Background technique [0002] A gas turbine is a rotary power machine that uses continuously flowing gas as a working medium and converts the thermal energy of the working medium into mechanical work. Taking a simple cycle gas turbine as an example, it mainly includes a compressor, a combustion chamber and a turbine. The working process is as follows: the compressor sucks in air from the atmosphere and compresses it. The compressed air enters the combustion chamber and mixes with the injected fuel to generate high-temperature gas. The high-temperature gas flows into the turbine to expand and do work, and the turbine is driven to rotate to convert the high-temperature gas energy into rotating mechanical energy output, and the gas after work is directly discharged into the atmosphere. [0003] Gas turbines are usually operate...
