Cleaning agent automatic filling gas turbine gas compressor blade cleaning device

Abstract

The invention discloses a cleaning agent automatic filling gas turbine gas compressor blade cleaning device. The cleaning device comprises a water storage tank and a cleaning agent tank. The cleaningagent tank is used for storing a cleaning agent. The water storage tank is used for storing clean water. The cleaning agent tank is provided with a cleaning agent delivery pipe. A delivery pump is arranged on the cleaning agent delivery pipe. The water storage tank is provided with a water supply pipe. A water delivery pump is arranged on the water supply pipe. The cleaning agent delivery pipe andthe outlet end of the water supply pipe are collected together to be connected with a water supply line. The water supply pipe line is used for supplying water for blade cleaning. By automatically starting the delivery pump, the cleaning agent can be filled conveniently. Meanwhile, the matching concentration of the cleaning agent is accurately controlled through adjusting valves and flow meters arranged on a water supply pipeline and the cleaning delivery pipe, and the gas compressor blade water washing process is simplified. Waste of the cleaning agent and demineralized water is reduced. Thegas turbine offline water washing time is shortened. The available time of a gas turbine unit is prolonged.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a cleaning device for blades of gas turbine compressors that automatically adds cleaning agents. Background technique [0002] During the normal operation of the gas turbine, dust and oil mist in the air will accumulate on the compressor blades and stationary blades, thereby reducing the efficiency of the compressor and reducing the output of the gas turbine. Therefore, it is necessary to configure a compressor blade cleaning device and system to clean the dirty compressor blades so as to restore the performance of the compressor and the output of the unit. [0003] In order to restore the performance of the compressor to the greatest extent, it is necessary to use a cleaning agent when cleaning the compressor blades. At the same time, in order to ensure the cleaning effect and prevent the possible corrosion of the compressor blades caused by the cleaning agent, it is necess...

Problems solved by technology

However, the above two methods of adding cleaning agents have defects in use

The first method of adding cleaning agent manually needs to carry the cleaning agent to the top of the water storage tank to add and stir, which is very inconvenient to operate; in addition, in order to ensure the safe operation of the equipment, it is necessary to ensure that the liquid level of the cleaning agent mixture in the water storage tank is at a minimum After the cleaning is completed, this part of the cleaning liquid can only be directly discharged into the pit. At the same time, after each cleaning, the water storage tank must be cleaned with desalinated water before the next step of cleaning can be carried out, resulting in the accumulation of cleaning agent and desalinated water. unnecessary waste

The second way to independently configure the cleaning agent box, on the one hand, the location of the cleaning agent box is too high, and it is inconvenient to add cleaning agent; on the other hand, the viscosity of the cleaning agent is greatly affected by the temperature, which is easy to cause inhalation during actual use. A large deviation of the cleaning dosage will lead to a large deviation of the concentration of the cleaning agent in the cleaning solution, which will affect the actual cleaning effect
