Wet-cold thermal power generating unit and wind energy combined utilization power generation device

Abstract

The invention relates to a wet-cold thermal power generating unit and wind energy combined utilization power generation device. The device comprises a circulating water return pipeline, a plant area preheater, a circulating water return pipeline radiator, a water-wind surface heat exchange cooling tower, a wind driven generator and a wet-cold water cooling tower. The circulating water return pipeline is connected with the water inlet end of the plant area preheater, the plant area preheater comprises a plant area heat supply network preheater, a plant area life preheater and a raw water heaterwhich are connected in parallel, the water-air surface heat exchange cooling tower is in a circular truncated cone shape, a forced circulating water-air cooler is arranged in the water-air surface heat exchange cooling tower, two arc-shaped air distribution grooves are formed in the two sides of the wind driven generator, and guide baffles are arranged on the arc-shaped air distribution grooves at intervals to form nozzle grooves. According to the wet-cold thermal power generating unit and wind energy combined utilization power generation device, through waste heat utilization of circulatingwater, the return water temperature of circulating water is reduced step by step, the evaporation area of the circulating water is reduced, and therefore, the consumption of the circulating water is reduced, and the effects of saving energy and reducing consumption are achieved.

Description

technical field [0001] The technology of the invention relates to the fields of a steam turbine circulating water cooling system in a thermal power plant and wind energy energy-saving utilization, and in particular relates to a power generation device for combined utilization of a wet-cooled thermal power unit and wind energy in a thermal power plant. Background technique [0002] With the rapid development of my country's power grid, the power generation forms of domestic power grid power points are also becoming more diverse. In recent years, with the leapfrog development of new energy power generation and water resource power generation, the profit margins of thermal power enterprises, which are traditional power generation models, have been further compressed In the face of the current situation, thermal power plants must increase investment and efforts in energy saving and consumption reduction, and further accelerate technological transformation and innovation. At presen...
