利用污氮气降低IGCC循环冷却水温度的方法及装置
摘要：
利用污氮气降低IGCC循环冷却水温度的方法及装置，通过管道将空分系统产生的污氮气引入冷却塔底部的换热填料下部，并通过管道上的配气喷嘴，使污氮气均匀地分布在冷却塔底部；污氮气通过冷却塔上下部压差，向冷却塔上部流动，通过换热填料，与循环冷却水完成逆流传热传质过程，实现循环冷却水的降温；本发明可以广泛用于采用深冷空分与湿式冷却塔的IGCC电站中，特别是采用低压空分系统的IGCC电站；本发明同样可以应用于任何存在深冷空分与循环冷却水需求的场合；能够有效降低循环冷却水温度，提高汽轮机的出力，提高发电效率。
摘要（英）：

The invention discloses a method and a device for reducing an IGCC circulating cooling water temperature by using polluted nitrogen. The polluted nitrogen generated by an air separation system is leaded to the lower part of a heat exchange filler at the bottom of a cooling tower through a pipe, is evenly distributed at the bottom of the cooling tower through an air distribution nozzle on the pipe, and flows to the upper part of the cooling tower through the pressure difference of the upper and lower parts of the cooling tower to finish the countercurrent heat and mass transfer process with circulating cooling water through the heat exchanger filler so as to realize the cooling of the circulating cooling water. The method and the device can be widely applied to an IGCC power station adopting a deep cooling air separation and wet cooling tower, in particular to an IGCC power station adopting a low-pressure air separation system; the method and the device also can be applied to any occasions needing the deep cooling air separation and the circulating cooling water; the temperature of the circulating cooling water can be effectively reduced; the capacity of a gas turbine is improved; and the electricity generation efficiency is improved.
