A hydropower station waste heat recovery unit

Abstract

The invention relates to a hydropower station waste heat recovery unit. The hydropower station waste heat recovery unit comprises a bottom plate. Two connected units are installed at the upper end of the bottom plate; a waste heat recovery device is installed on the outer walls of the units in a surrounding manner; the waste heat recovery device comprises four first water pipes surrounding the outer walls of the two units; the middles of the two ends of the four first water pipes are connected with a second water pipe penetrating the upper portions of the two units; two third water pipes are symmetrically arranged on the two sides of the second water pipe; the two ends of each third water pipe communicate with the two sides of the first water pipe on the uppermost portion; the second water pipe is evenly provided with a row of fourth water pipes in the length direction; the middle of each water outlet pipe is connected with the bottom plate through a fixing column; the joints of the second water pipe and the fourth water pipes are connected with a water inlet pipe serving as a water inlet of outside cold water; and two U-shaped installing rings are symmetrically installed between the two units through screws. The hydropower station waste heat recovery unit can achieve the function of fully recycling heat dissipated by the units and has the beneficial effects of being simple in structure, good in heat recovery performance and the like.

Description

Technical field [0001] The invention relates to the technical field of hydropower station equipment, in particular to a hydropower station waste heat recovery unit. Background technique [0002] A hydropower station is a comprehensive engineering facility that converts water energy into electric energy. It includes a series of hydroelectric power station buildings and various hydroelectric power station equipment built by using water energy to produce electricity; these buildings are used to concentrate the drop of natural water flow to form a water head and gather , Regulate the flow of natural water flow, and send it to the water turbine. Through the combined operation of the water turbine and the generator set, the concentrated water energy is converted into electrical energy, and then the electrical energy is input into the grid through transformers, switch stations and transmission lines. [0003] Because the water pressure formed by the water drop is relatively large, the gen...
