Device and method for utilizing cyclic cooling water in cooling tower of steel plant to generate power

Abstract

The invention relates to a device and method for utilizing cyclic cooling water in a cooling tower of a steel plant to generate power. By improving the structure of the cooling tower, thegravitationalpotential energy of the cooling water is converted into mechanical energy, and then the mechanical energy is converted into electric-power kinetic energy to achieve the efficient utilization of resources. According to the method, by arranging a hydroelectric power generation unit above a water collection pool, the potential energy of the water is utilized to enable magnesium-aluminum lightweightcorrosion-resistant blades to rotate, the blades drive a power generator to generate power after accelerated by a speed changing gear, and the power is supplied to electrical equipment after output current is rectified and inverted. Compared with traditional cooling towers, the technology has the advantages that existing power generator equipment is utilized to convert the gravitational potentialenergy of the water freely falling into electric energy, the installation process is simple, the economic benefits are large, and meanwhile, the cooling efficiency of the cooling tower is improved.

Description

technical field [0001] The invention relates to a method of converting the gravitational potential energy generated by the industrial circulating cooling water in the cooling tower into electric energy, and supplying power to electrical equipment after rectification to realize efficient utilization of resources. Apparatus and method for generating electricity. Background technique [0002] The iron and steel industry is not only the basic industry of our national economy and the supporting industry of industrialization, but also a high energy-consuming industry. In the process of iron and steel production, electric energy is one of the important energy sources after coal, which involves every link in the production process. According to statistics, the average monthly power consumption of iron and steel plants is about 1.6×10 8 kwh, electricity consumption per ton of steel is 250~500kwh. In order to reduce power consumption, iron and steel enterprises have taken many meas...

Problems solved by technology

[0006] At present, wind power blades are mostly made of FRP. Although FRP has the advantages of light weight and high strength, its aging phenomenon is serious under the action of wind, sand, rain, snow, chemical media, mechanical stress, etc., and the interlayer shear strength is low.

Low-carbon martensitic stainless steel is widely used in water turbine blades, but its brittleness, high density, large resistance to power generation, and low efficiency
