Description
技术领域
本发明涉及根据权利要求1前述部分的用于潮湿物、尤其是残余废物减湿的压机。
背景技术
DE 199 09 328 A1公开了一种残余废物的处理方法,其中机械处理的残余废物通过需氧水解进行生物稳定化。在这种需氧水解的过程中,以逆流向待处理的残余废物提供水和空气,从而通过空气和沥虑流体的共同作用,残余废物的有机细胞被破碎,细胞液被释放。提供的碳分解成二氧化碳,溶解的和酸化的有机物由沥虑流体带走,也部分通过空气带走。通过这种需氧水解,可以加速的方式实际实现一种废物处理方法。
这样生物稳定化的残余废物具有相对低比例的干燥物,因此这个水解过程后必须进行脱水。在从DE 199 09 328 A1中得知的技术方案中,通过高压压机进行脱水,例如挤压压机。在类似的挤压压机中,待脱水的残余废物通过蜗轮吸进来、压缩,且挤压出的水分被带走。
人们发现以这种方式,残余废物中干燥物的含量仍然相对较低,因此需要相对高成本的残余废物的后续干燥。
发明内容
相比之下,本发明是基于提供用于潮湿物减湿的压机的目的,通过该压机,后续干燥的成本降低。
这个目的通过具有权利要求1的特征的压机得以实现。
根据本发明,该压机包括一个蜗轮,因此潮湿物可以从进料部分运输到出料口并进行挤压。除了这种机械挤压,潮湿物进一步暴露于加压的空气或者真空下,因此进行潮湿物的进一步的减湿。这就意味着根据本发明,机械减湿由对流减湿或者由真空减湿代替。但是,优选通过施加加压空气就可基本上实现减湿。
人们发现在初步实验中通过这种改变,待处理的潮湿物的干燥物含量在不进行后续干燥的条件下与传统技术方案相比显著提高,在处理残余废物的过程中干燥物的含量可以高达70%。这种装置的一个重要的优点就是由于干燥介质(干燥空气)或者真空的并行应用,用于制造压机的设备技术的成本只是稍微提高,因为必须的泵、管道等的安装成本很低。
在一个优选的实施例中,干燥介质通过一个由蜗轮包围的矛状中心管提供,所述中心管具有在一端形成的干燥介质的出口。然后干燥的介质以大体上横向于蜗轮的纵轴的方向流动通过潮湿物。
这个中心管可以是不可转动地或者与蜗轮一体旋转地安装。
如果在接近蜗轮外壳的出口嘴范围内设置滤网篮或者类似的装置,以阻止待处理的残余废物并允许负载的干燥介质的通过,那么负载的干燥介质的传输就尤为简单。
如果负载的干燥介质的提取通过减小压力的帮助得以实现,那么干燥介质的流动控制就尤为简单。
在类似的减压技术方案的情况中,在滤网篮的下游设置一个冷凝器,因此排出的湿气可被冷凝。
为了调节通过蜗轮的中间介导施加的机械加压压力,可以在压机材料出口提供压阻压力或者设置反压力装置,使得-根据待处理的潮湿物的稠度-可以设定不同的压阻压力。
在本发明处理残余废物的变体中,干燥介质提供有超过材料出口的压力大约1巴的压力,而在提取的范围内施加稍微减小的压力。
本发明的其它有利的发展是其他附属权利要求的主题。
附图说明
本发明的一个优选的实施例将参考下述简图更深入地解释,其中
图1是根据本发明用于残余废物的减湿压机的纵向截面图,和
图2是图1的压机的横截面示意图。
具体实施方式
在图1中表示的压机1包括蜗轮外壳2,其中蜗轮4是以可旋转的方式安装的。通过该蜗轮4的中间介导,残余废物6可通过进料装置8进入蜗轮间隔10并运输到材料出口12。通过蜗轮螺旋的合适节距,潮湿的残余废物6,即带水的残余废物被压缩,水分在该过程中被挤压出来。
蜗轮4具有矛状中心管14,蜗轮螺旋接合在中心管的外圆周上。中心管14的端部从蜗轮外壳2伸出。该端部承载一个传动小齿轮16,所述小齿轮可操作地与驱动电机20的输出齿轮18连接。在代表性的实施例中,传动小齿轮16和输出齿轮18通过皮带或者传送链22互相连接。
从蜗轮外壳2伸出的中心管14的端部与空气压缩机26通过耐压管路24进行连接,使得加压的空气可被注入中心管14中。
在代表性图1的中心管14的左侧端部,形成多个出口嘴28,加压空气可通过这些出口从中心管14排出。在图1代表的实施例中,这些出口嘴28仅仅沿着中心管14的一个端部形成,但是原则上可以在全长的中心管上设置这些出口。通过图1选择的技术方案,可以保证加压空气在残余废物已经以压缩的形式出现的范围内进入蜗轮间隔10。
在接近径向对着出口嘴28的位置,在涡轮外壳2的外周壁上形成滤网篮30,它被真空箱32包围着。这个真空箱32包括敞开到冷凝器36中的抽吸嘴34。冷凝器36的气室连接了一个真空泵38,因此真空箱32和冷凝器36可承受减小的压力,例如0.9巴。冷凝物40可通过阀门装置42进行提取并进行进一步的处理。
在代表性图1中的蜗轮外壳2的左侧端部设置一个压阻压力装置44,因此材料出口12的出口嘴的直径可根据实际情况进行修改,使得可在涡轮外壳2内构建反压力,反作用残余废物的轴向移动。
待脱水的残余废物6通过旋转蜗轮4进入蜗轮间隔10,并且根据图1的表示转输到左侧,进入被真空箱32包围的区域并且在该过程中被部分压缩。加压的空气以预定的过压通过空气压缩机26注入蜗轮4的旋转中心管14,该过压例如比通过压阻压力装置44施加的压力高约3巴。根据显示图1中压机的横截面的图2,未负载的加压空气46通滤网篮30的出口嘴28从中心管14径向喷出并冲击到待脱水的残余废物上。在由真空箱32包围的环状间隔48中,通过真空泵38施加减小的压力,使得加压的空气由于径向压力差(由压缩机26输送的加压空气的压力-真空泵38的减小压力)而流动通过残余废物6,其中径向即横向于蜗轮4的轴线。由于这种较高的压力差,在残余废物6中形成流动通道50,然而所述残余废物6具有恒定的变化过程。由于这种加压空气流和通过蜗轮4的残余废物的机械压缩的作用,水52从残余废物6挤出并且连同加压的空气46运输到真空箱48中。然后负载水的加压空气54沿箭头方向进入冷凝器36并且以上述的方式进行冷凝。通过材料出口排出的加压空气的量是可以忽略不计的。
通过上述的压机1,在处理含有有机成分的残余废物的过程中,可以调整干燥物的含量到60-70%,使得与传统技术方案相比残余废物的后续干燥的成本是最低的。
在上述的实施例中,蜗轮螺旋安装在中心管14的外圆周。实质上,中心管也可以不能转动的方式安装在蜗轮外壳2中,并且沿轴向延伸通过可转动驱动的蜗轮。
当然,上述压机1也可用于其它潮湿物的减湿。
在特定的操作条件下,压机1仅仅用加压的空气或者仅仅用真空进行操作是足够的。
本发明公开了用于潮湿物减湿的、尤其是用于残余废物减湿的、包括蜗轮的压机,因此残余废物可被机械压缩。在转运过程中在蜗轮的帮助下,潮湿物接触干燥介质,优选加压的空气或者真空,因此它从压机上进行传送。
