自新中国成立以来,我国尿素工业从无到有,不断发展壮大。从上世纪70年代中期开始,国内陆续引进建设了10余套以气提法工艺为代表的大型尿素生产装置,在其后的30多年内,国内又陆续建设了一批具有现代先进技术水平的若干套尿素装置,生产工艺不断更新改进,生产规模不断向大型化方向发展。但是高压洗涤器在开停车或运行工艺操作过程中,可能会发生爆炸,轻则造成高压洗涤器内筒防爆板破裂,尿素装置被迫排塔停车
Since the founding of new China, China’s urea industry from scratch, continue to grow and develop. Since the mid-1970s, more than 10 sets of large-scale urea production plants, represented by the gas extraction process, have been introduced in succession in China. Over the next 30 years, a number of large-scale urea production plants with modern advanced technology have been successively established A number of sets of urea plant, the production process continuously updated and improved, the scale of production continue to large-scale development. However, the high-pressure washer may open an explosion during the process of stopping or running the process, resulting in the rupture of the explosion-proof plate of the inner cylinder of the high-pressure washer and the urea device being forced to stop in the tower
