Description

群射流补燃式燃气器的群流器
技术领域
本发明涉及一种群射流补燃式燃气器的群流器，属于燃气器技术领域。
背景技术
燃气器是通过氧气和燃气混合燃烧的，目前市场上的燃气器一般为鼓风式燃气器，由电力驱动鼓风机进氧，使氧气与燃气混合燃烧。燃烧时，需要氧气与燃气同步混合燃烧，才能产生良好的燃烧效果。当出现鼓风机工作较慢时，进氧较少，和燃气混合后含氧量较少，则燃烧温度较低，热效率不高；当出现鼓风机工作较快时，进氧量大，和燃气混合后含氧量多，但是燃烧的热能会被产生的大风速带走，造成燃料消耗大，热效率低的后果。当出现停电时，鼓风机不能正常工作，此时燃气器不能正常使用。燃气的供气压力不正常也会造成燃烧的热效率低下。燃气一般储藏在钢瓶内，当钢瓶充满燃气时钢瓶内压力较低。在经过一段时间使用后，钢瓶内压力升高；当使用掉钢瓶内一半燃气后，钢瓶内的压力又逐渐减小。钢瓶中燃气压力前后的变化造成燃烧压力的不稳定，和氧气混合的不同，最终造成燃烧的热效率低下。同时，天气温度的变化也会造成钢瓶内燃气压力产生变化。天气温度高时，瓶中压力增高，燃气的出气量就大；天气温度低时，瓶中压力减小，燃气的出气量就小。由于上述的一些原因造成燃气与氧气混合燃烧的不同步，使得鼓风式燃气器的燃烧热效率低下。
发明内容
本发明的目的在于克服上述不足之处，从而提供一种群射流补燃式燃气器的群流器，能够将燃气分流成三档两路，使得燃气燃烧的热效率更高。
按照本发明提供的技术方案，群射流补燃式燃气器的群流器包括群流器主体、补燃小火进气管、补燃中火进气管和补燃大火进气管，其特征是：群流器主体中心设有贯通的主燃小火贮气仓，主燃小火贮气仓外圈设有补燃小火贮气仓，补燃小火贮气仓与补燃小火进气管连通。所述补燃小火贮气仓外圈设置补燃中火贮气仓，补燃中火贮气仓与补燃中火进气管连通。所述补燃中火贮气仓中设有贯通的多个主燃中火贮气仓，补燃中火贮气仓外圈设置补燃大火贮气仓，补燃大火贮气仓与补燃大火进气管连通。所述补燃大火贮气仓中设有贯通的多个主燃大火贮气仓。
优选地，所述补燃小火贮气仓为环形。
优选地，所述补燃中火贮气仓为环形。
优选地，所述主燃中火贮气仓为圆形，共有六个，六个主燃中火贮气仓以群流器主体圆心为中心均匀分布。
优选地，所述补燃大火贮气仓为环形。
优选地，所述主燃大火贮气仓为圆形，共有十二个，十二个主燃大火贮气仓以群流器主体圆心为中心均匀分布。
本发明与已有技术相比具有以下优点：
本发明结构简单、紧凑，合理；能够将燃气分流成三档两路，使得燃气燃烧的热效率更高。
附图说明
图1为本发明主视图。
图2为本发明后视图。
图3为图2中AA剖视图。
附图标记说明：1-补燃小火进气管、2-补燃中火进气管、3-补燃大火进气管、4-补燃小火贮气仓、5-补燃中火贮气仓、6-补燃大火贮气仓、7-主燃小火贮气仓、8-主燃中火贮气仓、9-主燃大火贮气仓、10-群流器主体。
具体实施方式
下面本发明将结合附图中的实施例作进一步描述：
如图1~3所示，本发明包括群流器主体10、补燃小火进气管1、补燃中火进气管2和补燃大火进气管3，所述群流器主体10中心设有贯通的主燃小火贮气仓7，主燃小火贮气仓7外圈设有环形的补燃小火贮气仓4，补燃小火贮气仓4与补燃小火进气管1连通。所述补燃小火贮气仓4外圈设置环形的补燃中火贮气仓5，补燃中火贮气仓5与补燃中火进气管2连通。所述补燃中火贮气仓5中设有贯通的六个圆形的主燃中火贮气仓8，六个主燃中火贮气仓8以群流器主体10圆心为中心均匀分布。所述补燃中火贮气仓5外圈设置环形的补燃大火贮气仓6，补燃大火贮气仓6与补燃大火进气管3连通。所述补燃大火贮气仓6中设有贯通的十二个圆形的主燃大火贮气仓9，十二个主燃大火贮气仓9以群流器主体10圆心为中心均匀分布。
射流是指流体依靠出流动量的原动力，喷射至另一流体域中的流动。群射流补燃式燃气器根据射流原理，采用多孔射流引流的方法，提供三档燃气用量选择，主补双路进气，多环燃气燃烧。三档燃气通过风门管座分成主补两路燃气，补燃气路燃气进入群流器后通过导流盘、多环扩散盘喷射出，将周围的空气喷射至补燃气路出口，与补燃气路出来的燃气混合燃烧。补燃气路燃烧后又点燃主燃气路燃气，在点燃的同时，补燃气路又压迫主燃气路燃气，防止主燃气路燃气喷射的太远。在燃烧时，主燃气路燃烧时状态稳定，火焰温度高，可达1350℃。
本发明用于群射流补燃式燃气器的进气燃气分路，燃气通过本发明分成大中小三档，分成三档后又分流成主补两个气路，经过两次分流的燃气通过不同的路径达到喷嘴喷射出，然后与氧气混合。主燃气路中的燃气与氧气混合成不易燃气后由附近的补燃气路的易燃气燃烧产生的小火点燃，使之剧烈燃烧，火焰温度可达1350℃。
本发明适用于各种低压气源家用燃气灶，食堂猛火中压燃气灶，高压锅炉。
