Cooling water system for turboset and cooling water supplying method

Abstract

The invention provides a cooling water system for a turboset, which includes a first turbine generator set and a second turbine generator set, wherein cooling equipment is arranged inside the second turbine generator set; and the cooling water system further includes a second turbine generator set water reuse system, a second turbine generator set forebay, and a second turbine generator set machine room. The cooling water system adopting the first turbine generator set and the second turbine generator set provides two paths of water sources to cool the cooling equipment, enables the two paths of water sources to be alternatively used during heat supply, solves the problems that the cooling equipment cannot be cooled completely and the loss of a cold source is huge in a big generator set for generation in case of winter heat supply, maintains the operation efficiency in summer for generation at the same time, and has the characteristics of simple structure, reasonable design, convenience for mounting and operation, low construction cost, remarkable energy-saving effect and the like.

Description

technical field [0001] The invention relates to a cooling water system, in particular to a cooling water system for a steam turbine unit, and also relates to a supply method, in particular to a cooling water supply method. Background technique [0002] With the continuous improvement of people's living standards, the heating area has been continuously developed and the heat supply has been increasing. As one of the government's "people's livelihood" projects, heating work involves the quality of life of thousands of households and has been increasingly valued. Therefore, the development of new heating technology has become a good exploration to ensure the reliability of heating, which has important social significance. At present, my country's heating status is mainly based on steam extraction heating and small unit low vacuum back pressure heating technology, and there are a few areas where ground source heat pumps are used for cooling and heating. In addition, due to the ...

Problems solved by technology

However, in the heating system of a large unit, a large number of equipment that needs to be cooled in time is installed inside the steam turbine unit, such as air coolers, generators, etc. The traditional cooling method is often due to insufficient cooling water flow or pressure of a single large unit, such as in In the Chinese patent CN1916506A, a single cooling water supply system and supply method are provided. This single cooling water system cannot sufficiently cool the numerous cooling equipment in the large unit, thus causing these devices to overheat and cause accidents
