摘要: 为充分利用空冷塔内部空间,减少厂用地面积及节约投资,在主机冷却系统采用间接空冷系统时,提出了将脱硫吸收塔、湿式电除尘器及烟囱合理地布置在空冷塔内的“间冷塔四合一”设计方案。通过数值模拟试验,研究了“间冷塔四合一”布置中间冷塔的流动传热性能和热力性能,得出了间冷塔的最小防冻流量以及塔筒内壁的防腐范围。

Abstract: To take full advantage of the internal space of the air cooling tower, reduce land occupation and save budget, the layout plan of Four-in-One indirect cooling tower is proposed regarding the steam turbine cooling system with indirect natural draft cooling system, in which the desulfurization absorber tower, the wet electrostatic precipitator(ESP) and the stack are integrated together into the cooling tower. Furthermore, based on the numerical simulation, the heat transfer performance and thermal performance of the cooling tower are studied. Therefore the recommended minimum anti-freezing water flow and the anticorrosion area of the inner wall of the cooling tower are obtained.

Key words: thermal power plant, indirect natural draft cooling system, desulfurization absorber tower, wet electrostatic precipitator (ESP), stack, anti-freezing water flow, anticorrosion area
