Description

一种燃油燃气锅炉节能器 技术领域
本实用新型涉及一种燃油燃气锅炉中的装置，具体涉及一种燃油燃气锅炉节能器。
背景技术
燃油燃气锅炉工作过程中产生的高温烟气含有大量的热能，如果直接排放到空气中会造成资源浪费。为此，现有技术中设计了多种用于回收燃油燃气锅炉烟气热量的节能器，常见的节能器是在烟筒内密布水管，烟气在筒内从下向上流动，与水管内的水进行热交换，水吸热后供给锅炉使用，从而实现烟气热能的回收利用。但是现有的节能器中，烟筒设置成直筒结构，烟气在筒内的流动路劲短，因此与水管接触的时间少，使得水与烟气不能进行充分的热交换，能量回收率有待提升。
实用新型内容
本实用新型的目的在于克服现有技术的不足，提供一种燃油燃气锅炉节能器，该节能器延长了烟气在外筒内的流动路径和停留时间，使得换热更加充分，提高了能量的回收率。
本实用新型解决上述技术问题的技术方案是：
一种燃油燃气锅炉节能器，包括圆柱形外筒和设在外筒内的水管，其中，所述外筒上连接有烟气进口和烟气出口，所述水管上设有进水口和出水口；其特征在于，所述外筒内设有螺旋形烟气通道，该螺旋形烟气通道的一端与烟气进口连接，另一端与烟气出口连接；所 述水管包括位于外筒中心的中心水管以及环绕在中心水管外的外围水管；所述螺旋形烟气通道由内筒的内壁、中心水管的外壁以及连接在内筒的内壁和中心水管的外壁上的螺旋形分隔板围成；所述水管沿上下方向穿插在所述螺旋形分隔板上。
本实用新型的一个优选方案，其中，所述烟气进口和烟气出口由连接在外筒的底部和顶部外壁上的烟气管构成，该烟气管的内壁与外筒的内壁相切。这样有利于烟气顺畅地进出螺旋形烟气通道，减少流动阻力。
本实用新型的一个优选方案，其中，所述外围水管包括若干组沿圆周方向均匀分布的水管组，每组水管组的底端和顶端均与环形水管连通；位于顶端的环形水管以及中心水管之间设有将其连通的连通管，所述中心水管的顶端构成进水口；位于底端的环形水管以及中心管之间也设有将其连通的连通管，所述出口与位于底端的最外侧的环形水管连通。这样便于水管的布置和安装。
本实用新型的一个优选方案，其中，所述外筒的顶端和底端分别设有顶盖和底盖。烟气从外筒的侧向进出螺旋形烟气通道。
本实用新型与现有技术相比具有以下的有益效果：
本实用新型中，由于设置了螺旋形烟气通道，使得烟气在该通道内进行螺旋形流动，延长了烟气在外筒内的流动路径和停留时间(相对于同等高度的外筒)，使之有足够的时间与水管内的进行热交换，使得换热更加充分，提高了能量的回收率。

具体实施方式
下面结合实施例及附图对本实用新型作进一步详细的描述，但本实用新型的实施方式不限于此。
参见图1～图4，本实用新型的燃油燃气锅炉节能器包括圆柱形外筒1和设在外筒1内的水管，其中，所述外筒1上连接有烟气进口2和烟气出口3，所述水管上设有进水口5和出水口6。所述外筒1内设有螺旋形烟气通道，该螺旋形烟气通道的一端与烟气进口2连接，另一端与烟气出口3连接。所述水管包括位于外筒1中心的中心水管7以及环绕在中心水管7外的外围水管8。所述螺旋形烟气通道由内筒的内壁、中心水管7的外壁以及连接在内筒的内壁和中心水管7的外壁上的螺旋形分隔板11围成。所述水管沿上下方向穿插在所述螺旋形分隔板11上，并穿越所述的螺旋形烟气通道。
参见图1～图4，所述烟气进口2和烟气出口3由连接在外筒1的底部和顶部外壁上的烟气管构成，该烟气管的横截面呈矩形，该烟 气管的内壁与外筒1的内壁相切，这样有利于烟气顺畅地进出螺旋形烟气通道，减少流动阻力。
参见图1～图4，所述外围水管8包括两组沿圆周方向均匀分布的水管组，每组水管组的底端和顶端均与环形水管9连通；位于顶端的环形水管9以及中心水管7之间设有将其连通的连通管10，所述中心水管7的顶端构成进水口5，水从进水口5进入后，通过所述连通管10和环形水管9进入到各个外围水管8中；位于底端的环形水管9以及中心管之间也设有将其连通的连通管10，所述出口与位于底端的最外侧的环形水管9连通，各个水管中的水自上而下流动后，经过该环形水管9和连通管10汇集到出水口6中排出。

上述为本实用新型较佳的实施方式，但本实用新型的实施方式并不受 上述内容的限制，其他的任何未背离本实用新型的精神实质与原理下所作的改变、修饰、替代、组合、简化，均应为等效的置换方式，都包含在本实用新型的保护范围之内。
