The technical scheme adopted by the invention for solving the problems is as follows: the method comprises the following specific steps:
the method comprises the following steps that firstly, tee joints, valves and pressure gauges are added to all pipeline terminals before a unit runs;
step two, when the unit is stopped and maintained, a valve on one pipeline on the unit is opened and is connected with the air compression equipment, and the air compression equipment is started after the connection is finished;
step three, observing the numerical value of the pressure gauge at all times after the air compression equipment is started, stopping increasing the pressure of the air compression equipment after the preset pressure is reached, and keeping the pressure at the moment;
and step four, repeating the step two and the step three on other pipelines on the unit, and finally finishing the removal of the microorganisms in the pipelines on the whole unit.
Furthermore, in the first step, one end of the tee joint is connected with the pipeline, the other end of the tee joint is connected with the pressure gauge, and the middle end of the tee joint is connected with the valve.
Further, after the air compression equipment is started in the step two, the pressure of the air compression equipment is increased by a pressure value of 0.5-1 MPa per minute.
Further, the preset pressure value in the third step is 5MPa-20 MPa.
Further, the time for maintaining the preset pressure value in the third step is 60min-120 min.
The invention has the beneficial effects that: according to the invention, the tee joint, the pressure gauge and the valve are added at each pipeline terminal of the pumped storage unit, the valve is connected with the air compression equipment in the regular maintenance process of the unit, pressure is applied to the pipeline according to the length and the structure of the pipeline, and microorganism adhesion on the inner wall of the pipeline is removed one by one, so that the risk of corrosion failure caused by microorganism adhesion to the pipeline is solved, and potential safety hazards and great economic loss caused by microorganism corrosion of the pipeline of the pumped storage unit are avoided. The invention provides a method for removing microorganism adhesion on pipelines of a pumped storage unit, which is suitable for pumped storage units with different sizes, can select the placement positions and the number of an external valve, a tee joint and a pressure gauge according to the size and the structure of the pipelines, inputs different pressures into the pipelines according to the microorganism adhesion amount of the pipelines, controls the pressure of the external air compression equipment through the pressure gauge, and removes the microorganisms of the pipelines to the maximum extent. The invention can cover all types of pumped storage units, has lower cost and is easy to realize. The external air compressor adopted by the invention can not only remove microorganisms in the pipeline, but also remove silt accumulation, broken stone and other impurities at the position with larger curvature of the pipeline, thereby preventing the pipeline from corrosion failure, frictional wear and other phenomena caused by microorganism adhesion, prolonging the service life of the pipeline, ensuring the smoothness of pipeline water flow, avoiding potential safety hazard to the unit caused by the failure of the pipeline, improving the safe and stable operation of the unit and avoiding larger economic loss of the unit.
