为验证JH型轴流式搅拌桨的应用效果,进行了中试放大。试验在一个直径1m、容积500L的瑭玻璃反应釜内进行。试验有溶解、乳化和滴定反应三种搅拌形式。为满足工艺要求,JH轴流式搅拌桨实际安装高度为04dJ(dJ为桨径),离液面085m,为非正常安装。试验结果表明,在桨转速为166r/min时,效果最好。在相同条件下,使用JH型轴流式搅拌桨比原使用双层桨可提前1个多小时完成全部反应;在加快滴定速度,温度控制在30℃左右时,可提前2个多小时完成全部反应。在正常搅拌条件下,与原双层桨相比可降低功率耗损23%,节能约38%。
In order to verify the application effect of JH axial agitating paddle, the pilot test was enlarged. Test in a diameter of 1m, volume 500L 瑭 glass reactor. Test dissolution, emulsification and titration reaction of three kinds of stirring. In order to meet the technical requirements, the actual installation height of JH axial flow stirring paddle is 04dJ (dJ is the diameter of the paddle), 085m away from the liquid surface, which is abnormal installation. The test results show that when the paddle speed is 166r / min, the effect is best. Under the same conditions, the use of JH-type axial-flow impeller than the original use of double-layer paddle can be completed more than 1 hour ahead of all reactions; in accelerating the titration temperature, temperature control at about 30 ℃, can be completed more than 2 hours in advance reaction. Under normal stirring conditions, compared with the original double-layer paddle power consumption can reduce 23%, saving about 38%.
