The 40min is a reference value, and the third predetermined time may be adjusted as needed.
In an embodiment of the present disclosure, the fresh water washing step includes: starting the combustion engine to enable the rotating speed of the combustion engine to reach 300rpm; starting a water washing pump 19 to wash the compressor 1, the turbine 2 and the tail flue 3 with clear water through the first pipeline 7; after the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 discharge clear water, the combustion engine and the washing pump 19 are turned off.
Wherein, after the control part receives the signal that the third predetermined time has arrived, the second blow-off valve 11, the third blow-off valve 12, the fourth blow-off valve 13, the first electric valve 15 are controlled to be opened, and the combustion engine is started. The first electrically operated valve 15 may control the opening of the inlet guide vanes 4. After the control part receives the signal that the corresponding valve is opened and the rotation speed of the combustion engine reaches a preset value, the water washing pump 19 is controlled to start, and the second electric valve 18 is controlled to be opened. After the control part receives the signal that the washing pump 19 has been started and the second motor valve 18 has been opened, the fourth predetermined time (for example, 25 minutes may be allowed) is maintained until the second drain valve 11, the third drain valve 12 and the fourth drain valve 13 drain the clear water. After the control part receives the signal that the fourth preset time is up and the drain valves discharge clean water, the control part controls the water washing pump 19 and the second electric valve 18 to be closed. After the control part receives the signals that the water washing pump 19 and the second electric valve 18 are closed, the fuel engine is controlled to stop running.
In the present specification embodiment, the spin-drying step may include: starting the combustion engine to enable the rotating speed of the combustion engine to reach 300rpm; opening an air inlet guide vane 4 to 85 ℃, sucking air through the air compressor 1, and drying the air compressor 1, the turbine 2 and the tail flue 3; when the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 are discharged without water, the combustion engine, the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 are closed.
Wherein, after the control part receives the signal that the rotation speed of the combustion engine reaches 0rpm, the control part controls the start of the combustion engine. After the control part receives a signal that the rotational speed of the combustion engine reaches a predetermined value, the first electrically operated valve 15 is controlled to open the intake guide vane 4 to a predetermined angle. The predetermined angle may be adjusted as desired, for example, 85 degrees. After the control part receives the signals of the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 without water discharge, the control part controls the fuel engine to stop and controls the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 to be closed.
In the embodiment of the present disclosure, if the feedback signal that is missing is determined manually and cannot be ignored, the water washing system may be stopped before the fault is removed in time according to the feedback signal. Specifically, the water washing system may be provided with a stop button 26, and pressing the stop button 26 may stop the water washing system. Alternatively, the water wash system may be shut down by pressing down the stop button 26 during the water wash. The stopping step comprises the following steps: closing the water washing pump 19 and the corresponding valve; when the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 are discharged without water, the combustion engine is closed to have the rotating speed of 0rpm.
Wherein closing the respective valves includes closing the second electrically operated valve 18 and the flow control valve 16. After the control part receives the signals that the water washing pump 19, the second electric valve 18 and the flow control valve 16 are closed and the signals that the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 are not discharged by water, the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 are closed, and the gas engine is controlled to stop. After the control part receives the signals that the second blow-down valve 11, the third blow-down valve 12 and the fourth blow-down valve 13 are closed and the rotation speed of the combustion engine is 0rpm, the stop step is ended.
The control method of the gas turbine and gas compressor washing system provided by the specification has the following advantages:
1. the automatic starting and the automatic stopping of the water washing system in the full-stop state and the running state are realized;
2. The automatic starting of the washing system in the partial starting state is realized, and the original running state is not interfered;
3. Taking account of the manual judgment, the skip operation of the water washing system can be realized, when the condition of a certain step is not realized or is not satisfied, and the control part cannot receive the original signal to make the step impossible, the condition can be manually judged whether to be ignored, and if the condition can be ignored, the control button 14 can be pressed to continue to execute the subsequent steps until the completion; if the feedback signal cannot be ignored, the fault can be removed in time according to the received signal, the problem can be purposefully removed until the feedback signal is received, and the subsequent steps are continuously executed so as to continue cleaning. The shutdown button 26 may also be pressed to deactivate the water wash system prior to troubleshooting.
It should be noted that, in the description of the present specification, the terms "first," "second," and the like are used for descriptive purposes only and to distinguish between similar objects, and there is no order of preference therebetween, nor should it be construed as indicating or implying relative importance.

Any numerical value recited herein includes all values of the lower and upper values that are incremented by one unit from the lower value to the upper value, as long as there is a separation of at least two units between any lower value and any higher value. For example, if it is stated that the number of components or the value of a process variable (e.g., temperature, pressure, time, etc.) is from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, then the purpose is to explicitly list such values as 15 to 85, 22 to 68, 43 to 51, 30 to 32, etc. in this specification as well. For values less than 1, one unit is suitably considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples that are intended to be explicitly recited in this description, and all possible combinations of values recited between the lowest value and the highest value are believed to be explicitly stated in the description in a similar manner.
Unless otherwise indicated, all ranges include endpoints and all numbers between endpoints. "about" or "approximately" as used with a range is applicable to both endpoints of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30," including at least the indicated endpoints.
All articles and references, including patent applications and publications, disclosed herein are incorporated by reference for all purposes. The term "consisting essentially of …" describing a combination shall include the identified element, ingredient, component or step as well as other elements, ingredients, components or steps that do not substantially affect the essential novel features of the combination.
