Rotating-vane type coarse filtering apparatus

Abstract

The invention belongs to the technical field of gas turbines, disclosed a rotating-vane type coarse filtering apparatus, and the apparatus is used to solve the problems that because a conventional filtering apparatus employs a coarse filter for a long time, the pressure loss of an air inlet system is increased and the gas turbine efficiency is influenced, also the cost of manually mounting and dismounting a coarse filter is high, and air quality cannot be determined in advance. The rotating-vane type coarse filtering apparatus comprises a coarse filter device arranged in an air inlet channel of a gas turbine, the coarse filter device comprises a connection rod and multiple vertically-arranged coarse filters; the upper ends of the coarse filters are hinged in the air inlet channel, and the other ends of the coarse filters are all hinged to the same connection rod; and the bottom surface of the coarse filter at the downmost end in the air inlet channel is hinged to a telescopic cylinder or hydraulic cylinder, and the other end of the cylinder or hydraulic cylinder is hinged to the bottom end in the air inlet channel.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a rotary vane type rough-effect filter device for filtering air entering a gas turbine. The invention can also be used for air purification and filtration in other fields. Background technique [0002] A gas turbine is a rotary power machine that converts heat energy into mechanical work using continuously flowing gas as a working medium. In the main process of air and gas, the gas turbine cycle is mainly composed of three major components: the compressor, the combustion chamber and the gas turbine. [0003] The compressor inhales air from the external atmosphere, and pressurizes it step by step through the axial flow compressor, and the air humidity is also increased accordingly; the compressed air is sent to the combustion chamber to mix with the injected fuel to produce high-temperature and high-pressure gas Then enter the turbine to expand and do work, and p...

Problems solved by technology

[0009] The present invention solves the problem that the long-term use of the coarse-effect filter in the existing filter device causes the pressure loss of the intake system to increase and affects the efficiency of the gas turbine. At the same time, the cost of manual disassembly and assembly of the coarse-effect filter is high, and it is difficult to judge the air quality in advance, and provides a solution. A rotary leaf type coarse-effect filter device, which can decide to open and close the coarse-effect filter according to the weather, thereby solving the impact of the unused coarse-effect filter on the subsequent self-cleaning filter element, and avoiding the impact of long-term use of the coarse-effect filter Influence of air intake system pressure loss
