Internal corrosion protection system for gas turbine

Abstract

The invention relates to an internal corrosion protection system for a gas turbine. The internal corrosion protection system comprises a box body, an electric control module, a filtering pressure reducing valve group, an IP converter and a check valve, wherein a control panel is arranged on the box body, a liquid crystal screen and option buttons are separately arranged on the control panel, and the electric control module, the filtering pressure reducing valve group, the converter and the check valve are arranged in the box body; the liquid crystal screen and the option buttons are separatelyelectrically connected with the electric control module through wires; an inlet of the filtering pressure reducing valve group is connected with a gauge gas pipeline through a pipeline, an outlet ofthe filtering pressure reducing valve group is connected with an inlet of the IP converter through a pipeline, an outlet of the IP converter is connected with an inlet of the check valve through a pipeline, and an outlet of the check valve is connected with a pressure detecting opening of an outlet of an air compressor of the gas turbine through a pipeline; and the electric control module is electrically connected with the IP converter through a wire. The internal corrosion protection system has the advantages that the design is reasonable, the structure is simple, and the internal corrosion problem of the gas turbine is eliminated or delayed.

Description

technical field [0001] The invention relates to the field of gas turbines, in particular to a gas turbine internal corrosion protection system. Background technique [0002] The sea environment is humid and the salt spray is highly corrosive. Gas turbines are usually equipped with two engines for standby at sea. Usually, one of them must be shut down and in standby mode. When the gas turbine is shut down, due to its structural characteristics, the intake and exhaust ports are open to the atmosphere. Affected by micro-convection, humid salt spray air will gradually enter the inner core of the gas turbine, causing corrosion to the inside of the gas turbine. Especially affected by the process, the corrosion of long-term standby units is more serious. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a gas turbine internal corrosion protection system, which has a reasonable design and a simple structure, and realizes the er...
