Description
技术领域
本公开涉及用于颗粒材料挤压泵的拆分装置。
背景技术
煤气化涉及将煤或其他含碳固体转化为合成气。虽然在气化工艺中使用干煤和水浆,但是干煤泵运可能比水浆技术在热学方面更加高效。
为了精简该工艺并且提高干煤气化的机械效率,采用颗粒材料挤压泵来泵运粉状碳基燃料,例如干煤。颗粒材料挤压泵下游的粉状碳基燃料需要粉碎磨、球端磨或其他粉碎机械来拆分干煤。
附图说明
从所公开非限制性实施例的以下详细描述,本领域技术人员将会明白各种特征。该详细描述的附图可简要介绍如下:
图1是干煤挤压泵的透视图;
图2是拆分装置的剖视图;
图3是拆分装置的一个非限制性实施例的剖视图;
图4是拆分装置的另一个非限制性实施例的剖视图;
图5是各种拆分装置流动路径面积比和角度关系的图形表示;
图6是拆分装置的透视图,其具有流控制布置的一个非限制性实施例;
图7是拆分装置的剖视图,其具有流控制布置的一个非限制性实施例;
图8是拆分装置的剖视图,其具有流控制布置的另一个非限制性实施例;并且
图9是拆分装置的剖视图,其具有流控制布置的另一个非限制性实施例。
具体实施方式
图1示意性示出了用于运送干燥颗粒材料的颗粒材料挤压泵10的透视图。尽管所讨论的泵10用作粉状碳基燃料(如煤、生物质能燃料、石油焦、废料或其他给料)的运送工具,但泵10也可替代性地运送任何干燥的颗粒材料并且可用于各种其他工业中,包括但不限于:煤气化、石油化工、电力、食品和农业。
泵10通常包括入口区12、压缩工作区14和出口区16。入口区12通常包括加料斗18和入口20。压缩工作区14通常包括由移动壁24限定的通道22以及其驱动系统26。出口区16通常包括出口28和拆分装置30。
拆分装置30拆分在通道22内被移动壁24压实的煤。也就是说,粉状碳基燃料可从通道22被紧密地压紧。粉状碳基燃料具有自然休止角。也就是说,在一堆未压实材料的顶部处水平线与侧面形成的自然角。压实的粉状碳基材料已经被压缩成颗粒彼此附着形成团块(mass)的状态,该团块可以高于该自然休止角的角度不受支撑地竖直站立。被部分地拆分的材料可具有自然休止角,但仍由未压实和已压实材料的混合物组成,其可通过将最大的颗粒团块抵靠彼此或者抵靠装置表面剪切而被进一步减小。
参见图2,拆分装置30包括入口32和出口34,入口32限定第一截面,该第一截面大致等同于通道22形成的截面,出口34限定不同于第一截面的第二截面,以将被压缩的粉状已压实颗粒破碎成细粉坚实度(fine powder consistency)。在通过装置一次之后,碳基材料不再被防止以自然休止角堆放。入口32和出口34之间的流动路径36迫使粉状煤颗粒关于彼此移动,而不再次压紧。拆分装置30的入口32和出口34之间的流动路径36提供三维形状变化。流动路径36提供必要的颗粒破碎量,因为粉状碳基燃料被迫使改变方向并被允许在体积上膨胀。
参见图3,拆分装置30的流动路径36A的一个非限制性实施例提供:直线构成的入口32A作为第一截面,其大致等同于通道22形成的截面;以及限定第二截面的出口34A,该第二截面包括导圆角部。流动路径36A还转向至少九十(90)度转向角。
参见图4,煤拆分装置30的流动路径36B的另一个非限制性实施例提供:直线构成的入口32B作为第一截面,其大致等同于通道22形成的截面;以及限定第二截面的出口34B,该第二截面限定圆形出口。流动路径36A还转向至少九十(90)度转向角。
参见图5,从沿着流动路径36的该关系得出各种权衡折衷。应当理解,可在此使用沿流动路径36的面积比的各种组合。从直线构成的入口到圆形出口的过渡导致沿流动路径36B-1、36B-2、36B-3、36B-4的相对慢地面积增加,而同时相对更快地改变形状。相对简单(simple)的角也是有效的,但总效率可相对较小。
参见图6,煤拆分装置30的流动路径36C的另一个非限制性实施例提供:直线构成的入口32C作为第一截面,其大致等同于通道22形成的截面;以及各自限定第二截面的第一和第二出口34B1、34B2。应当理解,第一和第二出口34B1、34B2可以具有例如上述讨论的各种形状。流动路径36C还转向至少九十(90)度转向角。
参见图7,流动路径36可另外被布置成确保在粉状碳基燃料移动通过煤拆分装置30时流动路径36保持充满。在一个非限制性实施例中,流动路径36通过延伸部38而转向可大于九十(90)度转向角的转向角。该转向角可转向至少一百三十五(135)度转向角,其实质上限定J形。
参见图8,另一个非限制性实施例包括阀40(示意性示出)以确保在粉状碳基燃料移动通过煤拆分装置30时流动路径36保持充满。阀40可以是止回阀或需要预定压力以便通过被拆分颗粒材料的其他阀布置。
参见图9,另一个非限制性实施例设置干煤线性牵引机泵10,使得流动路径36沿着关于重力的方向布置以确保流动路径36保持充满。也就是说,煤拆分装置30可关于重力定位在干煤线性牵引机泵10上方,使得粉状碳基燃料抵抗重力而移动。
煤拆分装置30允许线性牵引机泵10在没有此前所需要的粉碎磨、球端磨或其他移动粉碎机械的情况下操作。
应当理解,在全部几幅附图中,相同的附图标记表示对应或相似的元件。还应当理解,尽管在所示实施例中公开了具体的部件布置,但其他布置也将从此受益。
尽管示出、描述和请求保护具体的步骤顺序,但应当理解,除非另有所指,所述步骤可按照任何顺序分离地或组合地执行,并将仍将从本公开受益。
前面的描述是示例性的而非被其中的限制所限定。本文公开了各种非限制性实施例,然而,本领域普通技术人员将会意识到根据上述教导的各种修改和变形将落入所附权利要求的范围内。因此,应当理解在所附权利要求的范围内,本公开可不同于所特别描述地来实施。为此,应当研究所附权利要求以确定真实范围和内容。
