介绍述了某厂引进德国的氢氧化铝焙烧炉用鼓风机转子进行重新设计改造的方案，该方案在不改变风机蜗壳和管道的前提下，使鼓风机进口风量由原来的66000m3／h提高到了81000m3／h，出口风压由原来的135784Pa提高到了144050Pa，同时使效率提高了15．7％。 Introduced the introduction of a plant in Germany, the aluminum hydroxide roaster with a blower rotor redesigned the program, the program without changing the volute and pipe under the premise of the blower inlet air volume increased from the original 66000m3 / h to 81000m3 / H, outlet pressure from the original 135784Pa increased to 144050Pa, while improving the efficiency of 15.7%.
