Description

一种节能自控的燃油燃烧系统
技术领域
本发明涉及一种节能自控的燃油燃烧系统。
背景技术
目前，工业燃油燃烧机中所采用的燃油燃烧系统一般都是采用高压油泵将油箱中的燃油输送到燃油喷嘴处，在高压油泵与喷嘴之间设有手动调压阀，在使用过程中需要根据实际情况人工调节，使用不方便，而且现有的燃油燃烧系统中一般采用燃油高压膨胀雾化的方式进行燃烧，这种方式燃油往往燃烧不充分，不利于节能减排。
发明内容
本发明的目的是为了克服现有技术中的不足之处，提供一种结构简单，使用方便，能自动调节的节能自控的燃油燃烧系统。
为了达到上述目的，本发明采用以下方案：
一种节能自控的燃油燃烧系统，其特征在于：包括集流三通阀，在所述的集流三通阀上分别连接有油箱，空气雾化式燃油喷嘴和一可将油箱中的燃油输送到空气雾化式燃油喷嘴并使燃油与空气充分混合的压缩空气机构，在所述的空气雾化式燃油喷嘴一端上设有自动点火装置，所述的自动点火装置与主控制器相连接，在所述的压缩空气机构上设有可检查并调节所述压缩空气机构工作的自控组件，所述的自控组件与所述的主控制器相连接。
如上所述的一种节能自控的燃油燃烧系统，其特征在于所述的压缩空气机构包括有与主控制器连接的交流电机，在所述的交流电机上连接有空气压缩泵，所述的空气压缩泵与集流三通阀相连接，在所述的交流电机上还连接有可将空气雾化式燃油喷嘴中燃油燃烧所产生的热量送入输热管道的风扇。
如上所述的一种节能自控的燃油燃烧系统，其特征在于所述的自控组件包括有连接在空气压缩泵与集流三通阀之间管路的压力传感器，所述的压力传感器与主控制器相连接，在所述的主控制器与交流电机之间设有变频器。
如上所述的一种节能自控的燃油燃烧系统，其特征在于所述的空气雾化式燃油喷嘴包括外接头和安装在外接头上的内接头，内、外接头内均设置有燃油通道，外接头端部设置有喷口，内接头外表面沿轴向设置有气流通道，外接头内有空腔，空腔内安装有旋转体，旋转体内贯穿有油道，油道与燃油通道相通，旋转体端面设置有凹槽，凹槽与气流通道相通。
综上所述，本发明相对于现有技术其有益效果是：
一、本发明结构简单，使用方便。采用空气雾化式燃油喷嘴替代现有技术中的高压膨胀式燃油喷嘴，使气油混合物更接近理想的空燃比、混合物在压缩空气的压力作用下旋转雾化而雾化效果更好，能达到燃油充分燃烧、减少有毒有害气体排放以保护环境的目的。同时克服原高压膨胀式燃油喷嘴因喷油孔过小易烧损的现象，油嘴寿命更长能减少燃烧机使用成本。
二、本发明引入变频调速的先进技术，以彻底实现气压及送热风扇的动态稳定控制、大大改善燃油燃烧状况，提高了电机的用功效率，并可达到有效降低电机额定功率减少电机生产成本的目的。
三、本发明系统具有优越性价比、节能环保，可以产生良好的经济效益和社会效益。

具体实施方式
下面结合附图说明和具体实施方式对本发明作进一步描述：
如图1所示的一种节能自控的燃油燃烧系统，包括集流三通阀1，在所述的集流三通阀1上分别连接有油箱2，空气雾化式燃油喷嘴3和一可将油箱2中的燃油输送到空气雾化式燃油喷嘴3并使燃油与空气充分混合的压缩空气机构5，在所述的空气雾化式燃油喷嘴3一端上设有自动点火装置6，所述的自动点火装置6与主控制器7相连接，在所述的压缩空气机构5上设有可检查并调节所述压缩空气机构5工作的自控组件4，所述的自控组件4与所述的主控制器7相连接。

主控制器7控制交流电机51工作，交流电机51驱使空气压缩泵52转动从而产生压缩空气，所述的压缩空气通过管路输送到集流三通阀1处，压缩空气从空气雾化式燃油喷嘴3喷出后，使集流三通阀1与油箱2之间的管路形成负压从而产生虹吸，燃油从油箱2中输送到空气雾化式燃油喷嘴3并与压缩空气充分混合，主控制器7控制自动点火装置6点火，空气雾化式燃油喷嘴3中的燃油点燃，风扇53同时工作，可以将空气雾化式燃油喷嘴3中燃油产生的热量吹入输送热量的管路，从而供给到用热设备。在这个工程中压力传感器41会侦测空气压缩泵52与集流三通阀1之间的气压，并向主控制器7发出信号，如果气压过高，主控制器7控制变频器42调低交流电机51的转速，如果气压过低，主控制器7控制变频器42提高交流电机51的转速，从而实现自动调节气压的目的。进而使空气雾化式燃油喷嘴3的出油量恒定。
工业实用性：
本发明适用于工业燃油燃烧机，能使燃油和空气混合充分，并能自动调节喷嘴出油量，能节省燃油的使用量，能极大改善燃烧状况，减少有毒有害气体排放。
