Improvement of the Work of a Small Derivative Hydro-Electrostation by Water Treatment by Hydrocyclones

Abstract

The relevance of the study lies in the fact that in the common derivation schemes of hydroelectric power plants, protection against bottom and bottom sediments is carried out in water inlets, and water is cleaned from dangerous fractions of sediments in sedimentation tanks. The costs for the construction of a sump are very significant and sometimes make up 20-35 % of the investments in the construction of hydroelectric power stations. In our opinion, it is possible to reduce these costs by using modern types of hydrocyclones instead of sumps and filters used to purify water for cooling generators. The purpose of the work is to increase the efficiency of small hydropower plants by improving the site of water treatment. The research method is the use of guidelines for the preparation of technical documentation for energy production and technological complexes of hydroelectric power stations and thermal power plants and the testing of a water treatment unit and a technical water supply system.
