此外，本领域普通技术人员应当理解，在此提供的附图都是为了说明的目的，并且附图不一定是按比例绘制的。
除非上下文明确要求，否则整个说明书和权利要求书中的“包括”、“包含”等类似词语应当解释为包含的含义而不是排他或穷举的含义；也就是说，是“包括但不限于”的含义。
在本发明的描述中，需要理解的是，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性。此外，在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
参照图1所示，本发明的一种气体处理设备，例如可以是塔扇，所述气体处理设备包括壳体1和设置在所述壳体1内部的贯流风轮2，所述贯流风/2竖向设置，所述壳体1上设置有进风口11和出风口12，所述出风口12的竖向中心线附近的出风方向大致位于所述贯流风轮2的径向上，如此，即使所述出风口12处不设置导风结构例如格栅结构，也可以使得所述气体处理设备的外观更加美观。
由于所述气体处理设备的内部设置有贯流风轮2，将所述气体处理设备的出风口12设置成所述出风口12的竖向中心线附近的出风方向大致位于所述贯流风轮2的径向上，虽然能够使得所述气体处理设备的外观更加美观，但是，这样设置会使得所述气体处理设备的出风量降低，为此，在所述贯流风轮2的转动方向上，由所述出风口12至进风口11的一侧的壳体1和贯流风轮2之间、靠近所述出风口12的位置设置蜗舌4，在所述蜗舌4的靠近所述出风口12的位置设置引导部41，所述引导部41包括大致沿所述贯流风轮2的径向延伸的第一引导部411和大致沿所述贯流风轮2的周向延伸的第二引导部412，在所述贯流风轮2的作用下，所述气体处理设备外部的空气经所述进风口11进入所述壳体1的内部，进入所述壳体1内部的空气部分沿所述第一导流部411从所述出风口12排出，另一部分沿所述第二导流部412回流至所述壳体1的内部，所述第一导流部411的设置使得进入所述壳体1内部的空气部分顺畅的从所述出风口12排出，所述第二导流部412的设置使得进入所述壳体1内部的空气部分顺畅的回流至所述壳体1的内部，进而减小空气阻力，降低能耗，通过逐渐缩小所述第二导流部412距离所述贯流风轮2之间的距离即可减小所述出风口12处空气回流至所述壳体1内部的空气量。所述第一引导部411和第二引导部412之间圆滑过渡连接，可以进一步减小空气阻力，减低能耗。
所述蜗舌4包括阻挡部42，用于阻挡气流沿所述出风口12向所述进风口11的方向回流至所述壳体1的内腔中，进而使得所述出风口12 处回流到所述壳体1内部的的空气量降低，所述气体处理设备的出风量提高。
