尿素造粒塔增设粉尘回收装置的技术初探

化肥厂尿素装置对大气的环境污染主要 塔顶部排放的尾气中氮及粉尘为主，治理尿素造粒塔的尘是改善化肥厂大气环境的关键，它既是一项环境保护措施，也是一项重要的节能降耗措施。

Probe into Technology of Dust Recycle Unit in Urea Graining Tower

Atmospheric environment pollution form the urea plant mostly originated in ammonia and dust in tail gas, discharging from the top of the urea graining tower. Treating its dust is a key, improving atmospheric environment of fertilazer plant. The project is a measure of environment protection not only, but also it is an important measure of saving energy and decreasing consumption.
