Abstract

The invention provides a seawater pump turbine unit and an electrolytic anti-fouling system and method for a technical pipeline of the seawater pump turbine unit, relates to the field of seawater pumpturbine anti-fouling technology, and aims to solve the problem of marine organism adhesion of the seawater pump turbine unit and the technical pipeline of the seawater pump turbine unit. The method includes the steps that seawater enters a seawater storage tank through a seawater collection pipeline, and the seawater in the seawater storage tank enters an electrolytic chlorine making device through a seawater filtration device and then enters an anti-pollution water storage tank after electrolysis by the electrolytic chlorine making device; and anti-pollution water in the anti-pollution waterstorage tank enters an inlet b, a volute water inlet c and an inlet d of the unit through a dosing pipeline, when available chlorine in the unit reaches the upper limit concentration, a dosing pump is closed by a dosing pump controller, and electrolytic anti-fouling of the seawater pump turbine unit and the technical pipeline of the seawater pump turbine unit is completed. The seawater pump turbine unit and the electrolytic anti-fouling system and method for the technical pipeline of the seawater pump turbine unit can be obtained.

Description

technical field [0001] The invention relates to the antifouling technical field of sea water pump turbines. Background technique [0002] With the rapid development of offshore wind power, tidal current power generation and offshore solar energy, it is forward-looking and necessary to build a seawater pumped storage power station to form a safe and stable smart regional power grid. The marine biofouling problem of sea water pump turbine is an important factor affecting the safe and stable operation of the unit. Especially for the technical pipeline of the unit, due to its small diameter and long length, it is very easy to adhere to marine organisms, which will seriously affect the monitoring and stable operation of the unit. At present, the antifouling technology of seawater environment mainly adopts antifouling coating and electrochemical antifouling and other means. Due to the high water head of seawater pumped storage, the antifouling coating is generally difficult to w...
