一种脱除后处理料液中亚硝酸的设备
摘要：
本发明属于核燃料后处理技术领域，公开了一种核燃料后处理Purex流程中用于脱除后处理料液中亚硝酸的设备。该设备包括脱除塔、空气发生装置和料液接收罐，其中脱除塔的上端置有料液进口，下端设置有空气入口，底端设置有料液出口，脱除塔的外塔壁上设置有加热装置；料液接收罐与脱除塔底端的料液出口通过料液输出管连接；脱除塔内部设置有填料，待处理料液从脱除塔的料液进口进入塔内与由空气入口进入的空气逆流接触。该设备具有亚硝酸脱除效果好、速度快、能连续操作且处理能力高的有益效果。
摘要（英）：

The invention, which belongs to the technical field of nuclear fuel reprocessing, discloses an apparatus for removing nitrous acid in reprocessing feed solution in the nuclear fuel reprocessing Purex process. The apparatus comprises a removal tower, an air generator and a feed solution receiving tank, wherein a feed solution inlet is arranged on the top end of the removal tower, an air inlet is arranged on the lower end of the removal tower, a feed solution outlet is arranged on the bottom of the removal tower, and a heater is arranged on the external wall of the removal tower; the feed solution receiving tank is connected with the feed solution outlet of the bottom of the removal tower through a feed solution output pipe; packing is arranged in the removal tower, and feed solution to be treated enters the removal tower via the feed solution inlet of the removal tower to be in countercurrent contact with the air entering the air inlet. The apparatus has the advantages of good nitrous acid removal effect, high speed, continuous operation and high treatment capability.
