A multi-stage parallel multi-line-water film electrode ion wind cooling tower water recovery device

Abstract

The invention discloses a multistage, parallel and multiline-water film electrode ion wind cooling tower water recovery device which comprises a multiline-water film electrode module set formed by connecting multistage and multiline-water film electrode modules in parallel. The multiline-water film electrode module set is arranged on the top of a large natural ventilation cooling tower. Each multiline-water film electrode module comprises silicon rubber compound insulator strings arranged on the periphery of a module supporting bracket, wherein multiple water film electrodes perpendicularly distributed are arranged in the module supporting bracket in parallel; multiline electrodes which are parallel to the water film electrodes and have an electrode interval are arranged at intervals along the water film electrodes; the multiple multiline electrodes are connected in a high-voltage direct-current power source in parallel through a connecting wire; and the water film electrodes are connected with the ground through a connecting wire. The multiple module supporting brackets are connected in a multistage and parallel manner through a supporting rope and conduct covering along the surface of an ion wind excitation area of the cooling tower. By means of the device, a multiline-water film electrode manner is adopted, generated ion jet flow and water mist in up flow of the cooling tower are combined, and the evaporation water damage recovery rate of water is increased by 12% to 45%.

Description

technical field [0001] The invention relates to a high-voltage corona discharge water recovery device, in particular to a multi-stage parallel multi-wire-water film electrode structure ion wind water recovery device for a thermal power plant cooling tower. Background technique [0002] At present, the shortage of fresh water resources has become an important restrictive factor for my country's economic development. As a basic industry of the national economy and an important energy industry, thermal power generation is a large industrial water consumer. The water consumption of a thermal power plant with an installed capacity of 1000 MW is equivalent to that of a medium-sized city (with a population of about 1 million). In wet-cooled thermal power plants, cooling towers are important auxiliary production equipment for thermal power plants, and their circulating cooling water consumption accounts for 60% to 80% of the total water consumption. The circulating cooling water wi...
