Description

Automatic alkali adding device for cold water in power plant

Technical Field

The invention relates to the field of cold water treatment equipment of power plants, in particular to an automatic alkali adding device for cold water of a power plant.

Background

A power plant is a plant that converts various primary energy sources stored in nature into electric energy (secondary energy). At the end of the 19 th century, with the growing demand for electricity, the idea of building electricity production centers began to be proposed. The development of motor manufacturing technology, the expansion of electric energy application range, the rapid increase of the demand of electricity for production and the consequent generation of power plants. The existing power plants have multiple ways of power generation, namely thermal power plants which drive turbines to generate power by using coal, oil or natural gas, hydroelectric power plants which drive turbines to generate power, small power plants which generate power by using water power, solar energy (photovoltaic), wind power and tide, and nuclear power plants which use nuclear fuel as energy have played an increasing role in many countries in the world.

Corrosion, fouling, plugging of the hollow conductors of the generator are of concern. In recent years, the problem of blockage of hollow conductors of foreign high-capacity generators occurs sometimes, the blockage degree cannot be developed to the ground step of damaging the generator, but the temperature of a coil bar is increased frequently, the load is reduced forcibly for operation, sometimes, in order to clean deposits, the machine needs to be stopped for maintenance, and the availability ratio of a unit is influenced. At present, the operation of cold water in a generator adopts closed circulation cooling, and in some power plants, the cold water is treated and supplemented with demineralized water, so that the pH value of the demineralized water is low, the corrosion of the system is caused, and the copper content of an internal cold water system is increased; in the prior art, the power plant mostly adopts micro-alkali treatment, namely a mode of injecting alkali water into cold water by a pump body, the quality of the alkali water directly determines the effect, but the defects are that the preparation and the production of the alkali water are needed manually, the quality of the alkali water cannot be ensured, and the mixed density between a solution and water cannot meet the requirements of people.
