Description
本发明涉及一种生活垃圾焚烧处理配套装置,属于生活垃圾焚烧处理配套设备的创新开发领域。
纵观当前小城镇及农村垃圾处理方法及配套设备,受地理条件等制约,还是以配套小型甚至最小型垃圾处理配套设备为主。但前提是必须充分认识到活垃圾焚烧处理技术的性能至关重要,因生活垃圾焚烧与环境因子和技术手段的相互协调息息相关,如天气、季节、垃圾成份,操作过程中的“勤”与“懒”等。还有垃圾本身含湿量以及产生的热值多少,会直接影响垃圾焚烧,烟气产生和处理质量等。
如中国专利号ZL201210003681.8的专利文献所公开的一种“小型垃圾焚烧炉”。所提供的这种垃圾焚烧炉,包括炉体与烟气处理配套设施。炉体上设有进料口,炉体从外到内由保温层、预热层与炉膛组成。预热层中间没有隔板,底部设置有聚热风槽。隔板之上设置有通气孔,炉膛置于聚热风槽上方,炉膛内由燃烧室与位于燃烧室上方的储烟室组成。燃烧室的底部一侧设置有总出烟口。炉内烟气从此处导出,进入烟气处理系统。由于此炉体改变了其它基本类似的焚烧炉的温度产生上下不连贯的不合理现象,故障率低、上下连贯畅通、燃烧效果好。
所公开的这种小型垃圾焚烧炉,主要体现在,空气预热、杜绝炉膛烟道结合部烧蚀、故障率低、延长使用寿命等。但是在这样的前提条件下,针对阻止二噁英合成及分解和抑制二噁英的形成;烟气的二次燃烧问题,没有相应的具体措施。
中国专利号CN201310050414.0的专利文献所公开的一种“烟气调质雾化酸碱综合反应塔”,所提供的这种“酸碱综合反应塔”,构体由上、中、下三个部分组成。上部是一个圆型箱体,箱体上方呈锥形。锥形的中央设有出烟管,出烟管悬挂于箱体中心,管底为人字形封底,烟管四围开有三个直条形出烟口,在出烟口的外空间,沿着锥顶板焊有一圈用扁钢制作的阻挡钩,在人字形的管底同样焊有阻挡钩,中间下垂呈人字形。整个箱底也同样呈人字形,并设有几个沿着四周等分的出烟口,在出烟口四周的实地焊有几圈一横一直相互交替均匀分布的阻挡钩,所有的阻挡钩悬挂在中部箱体的上部中央。整个固体坐落在一个与下箱体相等面积的中央。中部是一个长方形箱体,宽度与上圆体直径相等。一侧设置有进烟口,相对方向设置有反应材料入口。底部是反应材料搅动槽,在搅动槽的半圆中心配有传动构件,在槽底设置有反应材料作用后出口,外配密封门。下部设置有构体支持架,在支持架的一侧焊制有固定架,作用于传动电机的装配。操作前,从反应材料入口,直接投入反应材料,启 动传动构件,由抓斗抓起反应材料抛洒,使整个空间充满气雾状态,处理介质与气雾混合。使其在阻挡钩作用下,形成气旋呈紊乱状态,在反应箱内充分混合,增加综合反应效果。让其在这样的处理流场中有效释放化学反应成份。所提供的这种专利技术。主要体现在反应塔内制作混流处理流场来增加脱硫脱酸的时间步合理,反应材料的化学反应成份可有效地尽数释放。但在处理流程中没有考虑处理介质的含湿成份,对综合反应的影响因素。还有在处理流程中的蒸发,干燥和半干法综合反应程序,以及构体空间大小的合理性对化学反应效果的影响等。

本发明所配套的烟气冷却器,主要是将焚烧炉主体从总出口烟导出的高温烟气进行二次降温冷却,以水作为冷却源,高温烟气穿过置于水中的冷却管,实行冷热交换,达到处理介质一次降温冷却的目的,本技术冷却器改变其它由侧面和下部进入介质的广普性设置方法,在构体内部正中设置烟气出口。本发明的多管道烟气冷却器2包括主体,主体由外向内依次包括烟气出口管接2-1、储水室2-2、聚烟室、烟气气进口管2-3;烟气进口管2-3设置在多管道烟气冷却器正中位置,烟气进口管进口管2-3伸出冷却器顶平面;本发明的聚烟室围绕烟气进口管2-3设置且位于主体内;聚烟室由上部的上聚烟室2-4和下部的下聚烟室2-5组成,中部烟气进口管2-3的四周分别设置若干分支导烟管2-6;烟气进口管2-3插入下聚烟室2-5的管口,且底部设置有碰撞钩2-7,作用于分散烟气流动应力;聚烟室一侧,与分支导烟管并列,设置有烟气出口管接2-1的烟气出口导管2-8,烟气出口导管2-8伸出主体,通过置于水中的烟气导管实行冷却交换后的烟气从此处导出,进入下一处理单元。下聚烟室2-5最下部正中设置排尘口2-9,外部配密封盖;主体与烟气出口导管、聚烟室、烟气气进口管之间的其它空间均为储水室2-2;储水室2-2顶端一侧设置有原水进口2-10,底端一内里设置有排水口2-11,实现进水和排水,按保持一定水位线来控制进排水的位置。进排水流动的速度以实行冷热交换后的水温高低来决定。总的来说是以高温烟气通过冷热交换的效果来采取应对措施。为了保持构体的平稳和牢固性,底部四周配有支撑垫脚。
本发明多管道烟气冷却器主体部分由主体外围板2-12、主体顶板2-13和底板2-14构成;聚烟室由上烟池底板2-15、内围板2-16、下烟池底板2-17、顶板2-18、围板2-19、主体顶板2-13构成,主体内除去插入的管件,余下空间注入冷却原水。
本发明水膜加高压喷淋合成除尘器3包括主体,主体外部从上至下分别包括介质出口管接3-1、介质出口管管身向下穿过的储水池3-2、主体箱3-3、主体箱上的高压喷淋管进口管件3-4、主体箱的下部设置的介质进口管接3-5、与主体箱底部对接连通的尘灰水聚斗3-6、尘灰水聚斗底部设置的排水管接3-7及主体箱底部设置的支撑脚3-8;主体内,在储水池底部与主体箱顶部四周预设有一定的间隙作用于界定水膜形成的水膜口3-9;主体箱顶部设置有三圈紊乱钩3-10;主体箱中部设置有两组介质分流控制件3-11,在分两组介质分流控制件正中位置有上、下介质上行流动口3-12、3-13;在上、下介质上行流动口3-12、3-13及介质分流控制件3-11底部,设置有紊乱钩3-10;上、下介质上行流动口口3-12、3-13正上方设置有高压喷咀;高压喷嘴连接在高压力喷洒管3-14一端,另一端伸出与主体箱设置高压喷 淋管进口管件。储水池顶部设置有进水管3-15。
本发明所配套的水膜加高压喷淋合成除尘器与其它同类方案的构体外形大同小异,但内部构件构思新颖简单。为提高脱硫除尘器的质量和迅速降低烟气中的温度,阻止二噁英合成。烟气主处理室的内部处理流场为混流流动烟气处理流场。为了使其产生一定的压力梯度,增加利用带的粘性系数,在处理室上部的空间正中位置,设置有上下两组高压喷淋组合件,用罗纹钢筋支撑作为悬空设置。由分流控制件顶板,介质分流制件上行流动口。介质与水膜交融口、紊乱钩组成。在室顶出烟口管接底部的四周分布有紊乱钩,这样可控制处理室空间内部流动流场中的速度场、射流速度和主流速度比合理有序。高温烟气由进烟口进入处理室下部后。切向向上分流流动。因出烟口位置处于处理室顶盖的正中位置,与介质分流制件的上行流动口垂直对应。
为烟气分流流动的主流通口,在外力作用下所产生的烟气流动正应力迅速改变成剪切应力,必须配用引射设备引风机,促使处理室内混流处理流场的形成和有效除去烟气中的烟尘及重金属颗粒物。在烟气流动口正中位置设置有高压喷淋管、高压喷咀正对烟气上行流动口。高压喷淋水与呈朿流体流动的烟气接触碰撞,加速混流,增加脱硫效果。还可以将烟气进一步分流从处理室水膜与高压喷淋组合件之间的交融口高速流动,冲击水膜液面产生大量的液滴和水雾。烟气通过射流流动与液滴和水雾融合交换,进一步除去烟气中的烟尘及重金属颗粒物。高压喷淋组合件,所设置的顶板坡面,能使高压喷淋的边缘水在四周下淌,形成水簾,上下两组同时作用。烟气与水簾接触流动,可以起到辅助除尘的作用,在处理室顶和组合件顶板的底部所设置的紊乱钩,可以控制烟气向出烟口流动的速度,增加室内处理烟气的确停留时间。也是室内混流流场形成的重要环节,处理后的含尘水,由下部所设置的聚水斗和出水口用管道连接,排入处理水池,作为循环水利用,处理后烟气由穿过处理室顶部储水池的出口管接。用管道连接下一个处理单元,完成处理器内的处理流程。
本发明的烟气处理综合吸附塔见中国专利号“201820657303.4”公开的内容,该专利为本申请人于2018年5月4日申请。
本发明引风机5采用传导部件冷却型,以免长时间高速运转造成部件失真,影响正常传导,以B型传导方式为烟气系统配伍使用,风机侧开清灰孔,配密封门,底部配排水口管,以利于除去风机内气雾积水,减少腐蚀,延长风机使用寿命,减少维修费用。
在本发明最后端配套了排放组合体,改变了传统的烟气排放流程。创新了烟气采用单通道进入构体,由分布在进烟管四围的多个烟气导管回送至上部的排送烟室,从岀烟口进入排放烟管排放减少组合体内的大气压力,拉长了烟气在构体内的流程。促使了整个烟气处理流程的合理性。
烟气排放组合体6包括上部的排送烟室6-1、中部的导烟管6-2、下部的回送烟室6-3和烟气进口导管6-4;上部排送烟室顶盖呈锥形,由排送烟室锥顶板6-5、排送烟气直围板6-6、排送烟室底板6-7构成;排送烟室锥顶板6-5的正中位置设有烟气出口管接6-8;下部的回送烟室6-3,由回送烟室顶板6-9、回送烟室直围板6-10、回送烟室底板6-11构成;回送烟室下部配有清灰口6-12;烟气进口导管6-4直立部分处于主体中心位置且底部直通下部的回送烟室,横向平行伸出部分设置进口管接,烟气进口导管底部焊接有紊乱钩6-13;以进口导烟管直立部分为中心,四周均匀分布若干回送烟气的导烟管6-2,烟气从进口烟气导管进入下部的回送烟室,折回分流从回送烟气导管进排送烟室,从烟气出口管接处导出。烟气进口导管6-4与引风机5的送风管连接。
本发明技术所配套的焚烧炉主体,设置有一燃室和二燃室,由于二室之间设置有二次进风道。二燃室顶部设置有上旋式流动烟口和环抱式烟道,使得整个构体内烟气流程合理有序,故从二燃室导出的烟气温度较高。为迅速降低烟温阻止二噁英合成,在烟气处理系统依次配套了冷却降温和水膜+高压喷淋脱硫除尘设备,通过温法处理后的烟气中含湿量高,为了干燥烟气和进一步除去烟气中的酸性气体和二噁英等有机物及镉、铅、平均直径仅为40-80微米的重金属颗粒物。在温法处理后的基础上,配套了烟气综合吸附塔,烟气中的污染物在处理室内,通过与反应材料中合反应,沉降并通过塔内所设的活性炭吸附后。配套了引射设备引风机向烟气排放系统以分支折流的方式,通过烟气排放管排放。
本发明能使垃圾焚烧后所产生的浮升流动的烟气量小,膛内呈现的烟气流程合理有序。烟气通过多单元效应处理,能有效除去烟气中的酸性气体和二噁英有机物和重金属颗粒物。本发明尽管上文对本发明的具体实施方式给予了详细描述和说明,但是应该指明的是,我们可以依据本发明的构想对上述实施方式进行各种等效改变和修改,其所产生的功能作用仍未超出说明书所涵盖的精神时,均应在本发明的保护范围之内。
