Description

一种瓷砖生产线窑炉急冷带的余热回收利用装置
技术领域
本发明涉及陶瓷制造设备及利用方法,具体是一种瓷砖生产线窑炉急冷带的余热回收利用方法及装置。
背景技术
在陶瓷制造工艺过程的陶瓷烧制过程中,其烧制温度在1200℃左右,然后在窑炉急冷带对陶瓷吹冷风进行冷却,由于这一阶段陶瓷的温度变化需控制在一定的范围内,若温度变化过大,则会出现陶瓷裂等质量问题,因而现有的窑炉急冷带其窑顶部为密闭结构,即便此段温度达到500-700℃,因而也无人想到采取利用,其能量均是白白浪费,而且由于一般抽风机最多承受250℃的温度,对这一高温无法承受,也不能对其热量进行有效抽取,如此同时采用向内鼓冷风也使窑炉增加正向压力。
另一方面,陶瓷坯体原料经过研磨成泥浆,再送入干燥塔中喷雾干燥成坯粉,用于制坯,然后压坯成形进入窑炉烧制。在这种干燥塔中,需要配备热风炉或燃烧燃油来加热常温空气,使送入干燥室内的干燥雾状泥浆液滴受热成坯粉,如果喷射温度不高,雾滴大小不均匀,会造成坯粉粒度不均匀,坯粉产量不高,这样耗油量较高,生产成本高,经统计,一个瓷砖生产线其干燥塔每天所需能量成本超过2万元人民币,每月达70万元,同时由于能量的耗费对环境也造成一定的影响。
发明内容
本发明的目的是为了解决上述技术之不足,而提供一种能有效利用瓷砖生产线的窑炉急冷带余热并加以利用的方法。
本发明的另一目的还在于提供一种利用瓷砖生产线的窑炉急冷带余热并加以利用的余热回收装置。
本发明是通过下列方案实现上述目的的:它是通过在瓷砖生产线的窑炉急冷带的窑炉内腔顶部设置缓冲区域,然后再将缓冲区域内的热气接出加以利用。
将缓冲区域内的热气传输至瓷砖生产线的喷雾干燥塔内腔,即可实现喷雾干燥塔无需另加热源工作。
该瓷砖生产线窑炉急冷带的余热回收利用装置是在窑炉急冷带的窑炉上部设置抽热风管,该抽热风管与炉腔相通,在窑炉上部与连通的抽热风管之间设置有缓冲隔层,该缓冲隔层由上下隔层组成,上下隔层上均开有热气通孔。
作为上述方案的进一步说明,所述上隔层为平面,下隔层截面为弧形,二者构成拱顶形结构,上下隔层两端与窑炉侧壁固定连接在一起。
所述上隔层为重质高铝或碳化硅板,下隔层为莫来石或耐高温砖制成。
所述抽热风管的另一端与瓷砖生产线的喷雾干燥塔的上部塔顶内腔相通,构成喷雾干燥塔的热源装置。
所述抽热风管与窑炉急冷带的后段内腔上部相连接。
本发明的优点在于:本发明采用设置缓冲区间的方式使窑炉急冷带余热能得以利用,有效地节约了能源,由于在陶瓷产品生产中,目前喷雾干燥塔干燥粉料是通过热风炉烧水煤浆来实现,而本发明由从窑炉急冷带部分的热风管道连接至喷雾干燥塔来代替,其中从窑炉抽出热量温度约500℃~650℃,充分利用了窑炉,对窑炉的生产不受影响,干燥塔外也无须另外配置热风炉,节省了能耗,减少废气排放,适应了现在的清洁生产和环保需要,降低了生产成本,以市面日产粉料400吨喷雾塔为例,每天供热需耗水煤浆45吨,现在市场价为450元/吨的水煤浆,单此每天可在能耗上减少约2万元,另外其结构简单,也有利于推广;且本发明投资成本低,一条瓷砖生产线投资运行一个月后即可回收成本。

图2为本发明的余热回收装置作为喷雾干燥塔热源利用方法的结构示意图。
附图标记说明:1-瓷砖生产线、2-窑炉急冷带、3-抽热风管、4-干燥塔、5-排气风管、6-引风机、7-上隔层、8-下隔层、9-热气通孔。
具体实施方式
如图1、图2所示,本发明的瓷砖生产线窑炉急冷带余热回收装置,是在窑炉急冷带2的窑炉上部设置抽热风管3,该抽热风管3与炉腔相通,在窑炉急冷带上部与连通的抽热风管之间设置有缓冲隔层,该缓冲隔层由上下隔层(7、8)组成,上下隔层上均开有热气通孔9,所述上隔层7为平面,下隔层8截面为弧形,二者构成拱顶形结构,上下隔层两端与窑炉侧壁固定连接在一起,上隔层7为重质高铝或碳化硅板,下隔层8为莫来石或耐高温砖制成。抽热风管3一端与喷雾干燥塔4的上部塔顶内腔相通,另一端与窑炉急冷带2的后段内腔部相连接,急冷带2上部部分热量从缓冲隔层、热气通孔9被抽热风管3吸走至干燥塔4,构成喷雾干燥塔4的热源装置。该喷雾干燥4塔为锥底圆筒状的干燥塔,包括:进料管道、设置在进料管路上的泥浆泵,由泥浆泵将研磨好的泥浆液,通过泥浆管道深入塔室中部,并接通在塔室内的泥浆喷嘴上,泥浆由窑炉急冷带2余热风对泥浆进行加热后,经泥浆喷嘴喷出,在塔室内形成雾状泥浆,再经600℃以上的热风干燥成坯粉;设在塔底锥形壁上的排风管口,其伸出塔外的排风管道上依次接通有:连通塔内的引风机6和排气风管5,塔内气体由引风机6引入并经过管道除尘,通过排气风管5排出。
使用时,瓷砖经生产线辊道进入窑炉进行烧制,产生大量的热量,而在窑炉内急冷带需要对瓷砖进行一定范围内降温,它是通过在瓷砖生产线的窑炉急冷带的窑炉内腔顶部设置缓冲区域,然后再将缓冲区域内的热气接出加以利用,不影响窑炉内瓷砖的生产,将缓冲区域内的热气传输至瓷砖生产线的喷雾干燥塔内腔,即可实现喷雾干燥塔无需另加热源工作,经过热量调配利用,充分利用了能源,起到了节能环保的效果。
