Description
本发明涉及一种使用生物质燃料的炉具,尤其有关于一种使用由稻草、木屑、农作物秸秆等粉碎压制而成的小颗粒作为燃料并且火焰在燃烧区旋转燃烧从而大幅提高能量利用效率并减少烟尘污染的炉具。
生物质燃料是由稻草、木屑、农作物秸秆等粉碎压制而成的小颗粒。生物质燃料作为一种新型的能源因其卫生、环保、高效、经济等优势已经开始逐渐获得广泛的应用。
现有技术中常见的使用生物质燃料的炉具一般包括一个燃烧箱和一个辅助设备箱。辅助设备箱中一般容纳有料斗、在料斗底部与料斗相连通的送料筒、容纳在送料筒中的送料推杆、驱动送料推杆的送料电机、鼓风机、电源和配电箱。辅助设备箱表面设有开关和电源指示灯。燃烧箱中一般容纳有燃烧器、位于燃烧器上方的炉膛、以及设在炉膛上方的灶台。灶台的上方是热交换区。当打开电源开关后,送料电机开始驱动送料推杆转动,将从料斗中因重力作用而落下的生物质燃料颗粒经送料筒送入燃烧器中。落入燃烧器的生物质燃料颗粒经点燃开始燃烧,产生高温可燃气体。该高温可燃气体在炉膛中与鼓风机送入的空气中的氧气充分混合,产生剧烈燃烧,产生高温火焰。该火焰在灶台附近与需要加热的物体如锅炉、锅具等发生热交换。
但是这种现有生物质燃料炉具具有一些缺点。由于高温燃气与氧气混合不充分,所以整个燃烧过程并不充分。所带来的结果就是从灶台处排出的废弃含有较高浓度的未燃碳颗粒,会造成污染。另外,燃烧不充分也造成了热能的浪费,这种炉具的热效率有待提高。
为了减少未燃碳颗粒的空气污染、提高生物质炉具的燃烧效率,在中国发明专利申请 201210048170.8
'一种高效的炉具'中有揭露一种典型的现有生物质燃料炉具。如图 7 所示,该炉具 9 具有一个 燃烧箱 91 和一个辅助设备箱 92 。
燃烧箱 91 内容纳有一个燃烧器 93 ,燃烧器 93 具有一个燃料架板 94 。燃料架板 94
上方形成燃烧区 941 ,下方形成鼓风区 942 。燃料架板 94 上开设有数个通风孔隙。燃烧区的上方具有一个火焰区 96 ,火焰区 96 处设有一个补风装置
95 。补风装置 95 包括一个筒形内壁 951 、一个包围在筒形内壁 951 外侧的封闭式的送风室 952 、以及一条联通送风室 952 和鼓风区 942
的通风道 943 。辅助设备箱 92 内容纳有燃料输送机构和电气设备。燃料输送机构包括一个料斗 921 ,一条一端与料斗 921
下方的出口相连通另一端伸入燃烧区中的送料筒 922 ,以及一条可转动的容纳于送料筒中的燃料螺旋推送杆 923 。电气设备包括一部驱动燃料螺旋推送杆的送料电机
924 、一部可以向燃烧器内的鼓风区内送风的鼓风机 925 、电源和一个电源开关(图中未示)。该发明的特点是补风装置 95 的筒形内壁 951
上纵向设置有数个偏风装置 953 。
与传统的火焰区补风形式不同, 由于从每个偏风装置 953 进入火焰区的空气均变成顺时针或逆时针方向流入
,所以进入火焰区 内的空气是呈螺旋形式的。螺旋形式的补风气流不会在从各个偏风装置 953
进入的气流之间产生干涉,也不会形成风屏阻挡火焰的升腾,这样就可以形成稳定的火焰,提高能量的利用率。同时,螺旋形式的补风气流还可以将本来呈分散形态的火焰向筒形内壁的中心地带凝聚,使得火焰的加热更为集中,从而进一步增加能量的利用率。
但是,这种生物质炉具仍然具有一些缺点。虽然从偏风装置 953
处进入的氧气使燃烧变得更充分,但是同时,大量的、高速的氧气流经燃烧区,也会迅速带走尚未完全燃尽的碳颗粒,形成烟尘污染。第二,片面的靠增加氧气流量来提高燃烧效率很容易达到极限,因为到了一定的流量后如果再增加,过大的氧气流量反而会降低火焰温度。
本发明所要解决的技术问题是提供一种旋转火焰炉具,该炉具可以使燃气和空气充分混合,既烧尽燃气中所有的碳颗粒,也提高了燃气中的能量利用率。
为了解决这个技术问题,本发明提供了一种旋转火焰
的炉具,该炉具使用生物质燃料颗粒,并包括一个可安放于地面上的本体。
本体包括一个燃烧箱和一个辅助设备箱。燃烧箱包括一个顶面,顶面上开设有一个灶口。燃烧箱内容纳有一个燃烧器,燃烧器具有一个燃料架,燃料架上方形成燃烧区,下方形成鼓风区,燃料架上开设有数个通风孔隙。燃烧器的燃烧区和灶口之间具有一个火焰旋转装置,火焰旋转装置包括一个中空的圆柱形火焰旋转器,一条一端位于燃烧器的燃烧区上方、另一端以切线方向进入火焰旋转器柱形侧壁的火焰导入筒,以及一条一端联通火焰旋转器、另一端至灶口下方的火焰导出筒。辅助设备箱内容纳有燃料输送机构和电气设备。燃料输送机构包括一个料斗,一条一端与料斗下方的出口相连通、另一端伸入燃烧区中的送料筒,以及一条可转动的容纳于送料筒中的燃料螺旋推送杆。电气设备包括一部驱动燃料螺旋推送杆的送料电机、一部可以向燃烧器内的鼓风区内送风的鼓风机、电源
和 一个电源开关。
本发明所带来的有益效果是,由于火焰将在圆柱形的火焰旋转器内进行盘旋,而在整个盘旋过程中,火焰中所携带的氧气将充分与可燃气体混合并助燃。这样,在不增加氧气供应量和速度的情况下,火焰在火焰旋转器之内的停留时间得到延长,燃烧将变得更加充分。这样就既减少了未完全燃烧的炭颗粒的排放,也提高了热效率。

11 周边向上延伸的侧面 12 ,一个与侧面 12 上缘相连接并与底面 11 相对的顶面 13 。顶面 13 上开设有一个灶口 131 ,侧面 12
上开设有一个可开关的箱门 121 。
燃烧箱 10 内容纳有一个燃烧器 30 ,燃烧器 30 具有一个燃料架 31 ,燃料架 31
上方形成燃烧区 32 ,下方形成鼓风区 33 。燃料架 31 上开设有数个通风孔隙 311 。
燃烧器 30 的燃烧区 32 和灶口 131 之间具有一个火焰旋转装置 40 。火焰旋转装置 40
包括一个中空的圆柱形火焰旋转器 41 ,一条一端位于燃烧器 30 的燃烧区 32 上方、另一端以切线方向进入火焰旋转器 41 圆柱形侧壁的火焰导入筒 42
,以及一条一端联通火焰旋转器 41 、另一端至灶口 131 下方的火焰导出筒 43 。在图 5 所示的较佳实施例中,火焰旋转器 41 为横置,火焰导入筒 42
的一端以切线方向进入火焰旋转器 41 圆柱形的侧壁。而在图 6 所示的实施例中,火焰旋转器 41 为纵置,火焰导入筒 42 的一端以切线方向进入火焰旋转器
41 圆柱形的侧壁。
辅助设备箱 20 内容纳有燃料输送机构 50 和电气设备 60 。燃料输送机构 50 包括一个料斗
51 ,一条一端与料斗 51 下方的出口相连通另一端伸入火焰区 34 中的送料筒 52 ,以及一条可转动的容纳于送料筒 52 中的燃料螺旋推送杆 53
。电气设备 60 的电路图如图 7 所示,包括一台驱动燃料螺旋推送杆 53 的送料电机 61 、一台可以向燃烧器 30 的鼓风区 33 送风的鼓风机 62
、电源 63 ,一个电源开关 64 和电源指示灯 65 。电源 63 既可以是交直流电源 631 ,也可以在交直流电源 631 上并联蓄电池 632
作为辅助电源。交直流电源 631 和蓄电池 632 均能够单独供电。电源开关 64 安装于辅助设备箱 20 之上,可以控制整个电路的供电,开关指示灯 65
也安装于辅助设备箱 20 之上电源开关 64 附近,用来指示电源开关 64 的开合状态。
燃料 70 为生物质燃料,是由稻草、木屑、农作物秸秆等粉碎压制而成的小颗粒。
在使用时,使用者可以先在所需位置的地面上将本发明的本体 1 摆放平稳,向料斗 51 内倒入燃料 70
。当使用者按下电源开关 64 后,开关指示灯 65 亮起,表示电源接通,炉具开始工作。此时送料电机 61 转动,驱动燃料螺旋推送杆 53 将燃料 70
送入燃烧器 30 中,燃料 70 在重力作用下落在燃料架 31 上。此时使用者可以将点燃的酒精棉球投入燃料架 31 上,将上面的燃料 70
点燃。也是在同时,鼓风机 62 开始向鼓风区 33 送风,进入鼓风区 33 的风通过燃料架 31 上开设的通风孔隙 311 为燃烧区 32 上的燃料 70
的燃烧提供所需的氧气。当燃料 70 燃烧到一定程度时会产生低浓度的甲烷气体,这些甲烷气体在鼓风机 62 产生的气流的作用下产生火焰。火焰经火焰导入筒 42
以切线方向沿侧壁进入火焰旋转器 41 之内。由于进入的火焰具有初速度,火焰将在圆柱形的火焰旋转器 41
内进行盘旋。在整个盘旋过程中,火焰中所携带的氧气将充分与可燃气体混合并助燃。这样,在不增加氧气供应量和速度的情况下,火焰在火焰旋转器 41
之内的停留时间得到延长,燃烧将变得更加充分,热效率得到提高。旋转一段时间后的火焰将从火焰导出筒 43 处流出,流至灶口 131
,在此处与需要被加热的物体进行热交换。
当需要停止燃烧的时候,使用者可以断开电源开关 64 ,开关指示灯 65 熄灭,送料电机 61
停止转动,鼓风机 62 停止。没有新的燃料 70 供给燃烧,燃烧区 32 内的燃料将很快燃尽,使用者即可打开 箱门 121 ,清理鼓风区 33 内的灰烬。
燃料架 31 的边缘部分可以向上偏斜有一定角度,在中部形成一片低地。低地可以聚拢燃料 70 ,从而避免边缘燃料燃烧受热不充分产生黑烟。
如本技术领域的人所知,本发明的附图和实施例仅为说明本发明的功能、结构和原理而不应当成为对本发明理解上的限制;同时,本发明目的均已经实现。上述实施例可能在不脱离本发明原理的情况下有所变更,故此,本发明的保护应以权利要求书中所描述的范围为准。
