Embodiment 1

[0020] Taking a certain type of 360MW gas turbine as the application object, the block diagram of the gas turbine, the entire water washing device and its method is as follows figure 1 shown, with figure 1 Mark 101 is the compressor washing water tank, 103 is the heat exchanger, 104 is the gas turbine washing sewage tank, and 105 is the gas turbine washing sewage filter. In this embodiment, the unit runs for a period of time, and the channel of the compressor is fouled, which makes the performance of the unit decline. The gas turbine is washed with water to clean the fouling, so that the performance of the compressor is basically restored to the best operating condition. There are two ways to wash the compressor: offline water washing and online water washing. In this embodiment, online water washing is implemented.

[0021] The compressor water washing system mainly consists of water washing tank, cleaning pump, heat exchanger, water washing nozzle, water supply pressure regu...

Abstract

The invention provides a gas turbine compressor washing device and method. The device comprises a heat exchanger located behind the exhaust section of a gas turbine and a waste water filtering and recycling device of a gas turbine washing pollution discharge water tank. A compressor washing pipeline passes through the heat exchanger before entering a compressor. The heat exchanger heats gas turbine washing water through waste heat of tail gas of the gas turbine, the washing water temperature is increased, and the difference value between the washing water temperature and the wheel-wheel temperature is controlled to be within a set range. By means of the waste water filtering and recycling device of the gas turbine washing pollution discharge water tank, waste water in the water tank is filtered and recycled and flows back to a gas turbine washing tank to be recycled, and washing water is greatly saved. The washing cost is reduced, meanwhile, the compressor washing efficiency is improved, descaling is effectively achieved, the compressor performance can be basically recovered to the optimum condition, and it is ensured that a unit is safely and efficiently operated.

Description

technical field [0001] The invention relates to a gas turbine compressor water washing device and a method thereof, which are used for washing and cleaning the gas turbine compressor, so that the gas turbine compressor can operate in an optimal working condition and ensure the safe and efficient operation of the unit, belonging to the gas turbine auxiliary system. Background technique [0002] When the gas turbine is running, the air in the environment is filtered and flows through the channel of the compressor, and the tiny particulate matter carried in the air will be adsorbed on the compressor motor and stationary blades. , The aerodynamic performance of the stationary blade changes. After the compressor is fouled, it will have a great impact on the safe operation of the gas turbine. The specific manifestations are: the area of ​​the compressor channel becomes smaller, the lift coefficient decreases, and the drag coefficient increases, resulting in a decrease in the flow ...
