一种糠醛生产废水处理装置
本技术涉及一种糠醛生产废水处理装置,属于净化设备
技术介绍
糠醛产品是由玉米芯水解法生产糠醛,既聚物糖在酸性介质中水解成戊糖,戊糖经过脱水环化生产成糠醛,年产5000吨的糖醛厂一年的塔下废水约100000吨,每天约为200多吨废水,糠醛生产过程中的蒸馏塔下废水约为糠醛产量约20倍,而在废水里污染指数COD质量浓度为10000-15000mg/LPH<2,并主要含有醋酸、糠醛、以及醇类,醛类、酮类、脂类、有机酸类等多种有机物,经色谱、质谱分析有机物达40余种,其中应是醋酸和糠醛为主,这两类物质既是污染物质同时又是极有回收价值的生产原料和产品。由于废水量大,常规的废水处理方法,如膜分离法、萃取法,效率低,处理能力不足,成本偏高。
技术实现思路
为了解决上述问题,本技术提供了一种糠醛生产废水处理装置,具体技术方案是:一种糠醛生产废水处理装置,包括转筒,所述转筒为竖向设置,转筒为多孔结构,转筒内部设有活性炭层;转筒外部设有密封的套筒,转筒与套筒转动连接;所述套筒沿转筒的上部和下部设有隔板,隔板将套筒分隔成吸附腔和蒸发腔;所述吸附腔的顶部设有滴流管,滴流管与糠醛废水进口连接,吸附腔的底部设有净化水收集管;所述蒸发腔的底部设有蒸汽进口,蒸发腔的顶部设有负压管,负压管连接有冷凝器。进一步的,所述净化水收集管设有回流管,回流管与所述滴流管连接。进一步的,所述蒸发腔设有加热装置。本技术的有益点在于:本技术的方案是采用填充有活性炭的转筒对糠醛生产废水进行连续吸附和蒸发处理;对废水中的乙酸等成分进行分离和回收。具有废水处理能力大,效率高的优点。附图说 ...
