Description

一种尿素装置的氨冷凝器
技术领域
本实用新型涉及高效节能技术领域-能量系统节能综合优化技术，具体地说是一种尿素装置的氨冷凝器。
背景技术
目前我国现有的尿素装置氨冷凝器，无论哪一种流程都选用管壳式氨冷凝器，采用循环水冷却移走氨冷凝的热量。而且都安装在框架的顶部，高度在35米左右。这种方法运行费用高，消耗大量的水和电，造成大量的资源浪费。
发明内容
本实用新型的技术任务是针对以上不足之处，提供一种结构合理、运行费用低、节水节电、降低能源消耗的一种尿素装置的氨冷凝器。
本实用新型解决其技术问题所采用的技术方案是：该装置包括蒸发式氨冷冷器，液氨缓冲槽以及一吸塔；蒸发式氨冷冷器，液氨缓冲槽以及一吸塔通过管道串联连接，蒸发式氨冷冷器的顶部设置有轴流风机，蒸发式氨冷冷器外设置有循环水管，循环水管上安装有循环水泵。
所述的蒸发式氨冷冷器底部设置有溢流口和排污口。
工作时，从一吸塔来的气氨通过管道进入蒸发式氨冷冷器，冷却水由循环水泵送到蒸发式氨冷冷器上部的喷嘴，均匀地喷淋在蒸发式氨冷冷器外表面，形成一层很薄地水膜，在轴流风机的作用下将冷空气从下部吸入，使空气自下向上快速流动，水膜迅速蒸发带走热量。蒸发后的湿空气由上方的轴流风机抽走，从而使氨蒸汽冷却冷凝，被冷凝下来的液氨流往液氨缓冲槽。
本实用新型的一种尿素装置的氨冷凝器和现有技术相比，具有以下特点：
1、节电：采用蒸发式氨冷凝器后可使尿素装置的循环水系统节电60％以上。
2、节水：尿素装置的循环水用量降低50％以上。
3、投资运行费用低，该装置不需冷却塔和水池，投资费用大约下降10％。
附图说明
下面结合附图对本实用新型进一步说明。
附图为一种尿素装置的氨冷凝器的结构示意图。
图中：1、蒸发式氨冷冷器；2、循环水泵；3、轴流风机；4、液氨缓冲槽；5、一吸塔；6、循环水管；7、溢流口；8、排污口。
具体实施方式
下面结合附图和具体实施例对本实用新型作进一步说明。
本实用新型的一种尿素装置的氨冷凝器，其结构包括蒸发式氨冷冷器1，液氨缓冲槽4以及一吸塔5；蒸发式氨冷冷器1，液氨缓冲槽4以及一吸塔5通过管道串联连接，蒸发式氨冷冷器1的顶部设置有轴流风机3，底部设置有溢流口7和排污口8；蒸发式氨冷冷器1外设置有循环水管6，循环水管6上安装有循环水泵2。
本实用新型的一种尿素装置的氨冷凝器其加工制作非常简单方便，按说明书附图所示加工制作即可。
除说明书所述的技术特征外，均为本专业技术人员的已知技术。
