An integrated multi-stage air filtration system

Abstract

The invention belongs to the technical field of gas turbines, discloses an integrated multistage air filtration system, and solves the problems that production, manufacture and maintenance cost are high because the spaces among three stages of filters of a filtering chamber of a conventional gas turbine is too large, and solves the problem that because a conventional filtering system employs a coarse filter for a long time, the pressure loss of an air inlet system is increased, the gas turbine efficiency is influenced and artificial mounting / dismounting cost of a coarse filter is high. The integrated multistage air filtration system comprises a filtering chamber, and a coarse filtering device, a medium-efficiency filter and a high-efficiency filter arranged in the filtering chamber; the coarse filtering device comprises a connection rod and multiple vertically-arranged coarse filters, the upper end of the coarse filters are all hinged in the filtering chamber, 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 is hinged to a telescopic cylinder or hydraulic cylinder, and the other end of the cylinder or the hydraulic cylinder is hinged in the filtering chamber.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to an integrated multi-stage air filter system for air purification, which is used for purifying and filtering the intake air of a gas turbine. The invention can also be used for air purification 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 t...

AI Technical Summary

Problems solved by technology

[0009] The present invention solves the problem of high manufacturing and maintenance costs caused by the large distance between the three-stage filters in the filter room of the existing gas turbine, and at the same time solves the problem that the long-term use of the coarse-effect filter in the existing filter system causes the increase in the pressure loss of the intake system to affect the fuel consumption. Due to the high cost of machine efficiency and manual disassembly and assembly of coarse filters, an integrated multi-stage air filtration system is provided, which integrates three-stage filters to reduce the area of ​​the filter room, thereby reducing the manufacturing cost of the filter room. cost, reducing the maintenance time of staff and reducing maintenance costs; at the same time, it can decide to open and close the coarse filter according to the weather, thus solving the impact of the unused coarse filter on the self-cleaning filter element, and avoiding long-term use Influence of Coarse Efficiency Filter on Pressure Loss of Intake System
