Low-pressure air compressor blade cleaning device

Abstract

The invention provides a low-pressure air compressor blade cleaning device. The low-pressure air compressor blade cleaning device comprises nozzles (1), guide pipes (2), a liquid transporting pipe (3)and an air inlet passage (4). The air inlet passage (4) is assembled in an inlet of an air compressor and is in a horn mouth shape, and the multiple nozzles (1) are formed in the wall surface of theair inlet passage (4) in a penetrating mode in the circumferential direction. The liquid transporting pipe (3) is used for sucking cleaning liquid from an external container and annularly surrounds the outer side of a casing of the air inlet passage (4). The guide pipes (2) are connected and arranged between the liquid transporting pipe (3) and the nozzles (1) in the air inlet passage (4) to support the liquid transporting pipe (3) and transport cleaning liquid. Each nozzle (1) in the air inlet passage (4) is connected with the corresponding guide pipe (2) in a corresponding mode. According tothe low-pressure air compressor blade cleaning device provided by the invention, in-situ cleaning can be conducted under the condition that a gas turbine is not disassembled, and the performance of the gas turbine is improved to the initial state.

Description

technical field [0001] The invention belongs to the field of gas turbine design, in particular to the field of low-pressure compressor blades, and in particular to a low-pressure compressor blade cleaning device. Background technique [0002] Gas turbines need to operate for a long time in the field. After long-term operation, the low-pressure compressor blades will adhere to the surface of pollutants, causing changes in the blade shape, resulting in performance degradation, increased oil consumption of the gas turbine, increased user costs, and decreased profitability. The blades are located inside the gas generator. When the gas generator is shut down for maintenance, it can only be inspected through the hole probe. If the inspection finds that the blade surface is seriously polluted, the blades need to be treated. The components are decomposed into parts, the blades are repaired in the professional blade processing section, and then they are assembled and tested in the fa...

AI Technical Summary

Problems solved by technology

[0002] Gas turbines need long-term operation in the field. After long-term operation, low-pressure compressor blades will adhere to pollutants on the surface, causing changes in blade shape, resulting in performance degradation, and increased fuel consumption of the gas turbine, resulting in increased user costs and reduced profitability.

The blades are located inside the gas generator, and can only be inspected through a hole probe when the gas turbine is shut down for maintenance. If the inspection finds that the surface of the blades is seriously polluted, the blades need to be treated. The components are disassembled into parts, and the blades are repaired in the professional blade processing section, and then shipped after assembly and in-factory testing, which takes a long time
