针对上述问题，本发明型提供一种除尘效率高、节能环保、水循环利用的多机理湿式除尘设备及除尘方法。
为解决上述问题，本发明型采取的技术方案为： 一种水循环利用的多机理湿式除尘设备，包括粉尘捕集装置、粉尘沉降及气水分离装置、水循环装置和粉尘排出装置。
所述的粉尘捕集装置包括除尘风筒及其内沿轴线方向设置的至少一段同轴多环喷管，各段同轴多环喷管的管壁上分布有喷口，除尘风筒上端设有过滤入口，过滤入口只过滤不沉入水的纸片、树叶、塑料等物质，下端连接粉尘沉降及气水分离装置 。
所述的粉尘沉降及气水分离装置包括与除尘风筒下端密封连接的环状气液分流环槽、气液分流环槽下方的环槽导流管和沉淀水箱，气液分流环槽的槽底设有至少一个排水口，环槽导流管上端接至排水口，下端伸入沉淀水箱，且伸至沉淀水箱底部更有利于粉尘沉降，环槽导流管可垂直于水面，也可倾斜于水面设置；在气液分流环槽轴线方向设有含尘浓水导流管，所述的含尘浓水导流管下端伸入沉淀水箱，且伸至沉淀水箱底部更有利于粉尘沉降， 含尘浓水导流管可垂直于水面，也可倾斜于水面设置，上端伸出沉淀水箱上端；含尘浓水导流管上端位于气液分流环槽下方且其外径略大于或等于气液分流环槽内径，不妨碍环槽导流管的安装，且避免由除尘风筒中心区域落下的含尘水滴直接落入沉淀水箱，同时气液分流环槽与含尘浓水导流管上端之间的气流断面小于气水分离室外筒的气流断面，断面由小变大促使气体流速由高变低，气体中所含水滴在离心力和重力作用下从气水分离室外筒上空沉降，进一步气水分离。
所述的水循环装置包括设置于沉淀水箱上端外侧的溢流槽，溢流槽与沉淀水箱上端连通，所述的溢流槽连通有清水箱，清水箱经水泵接至同轴多环喷管上端。

根据上述的水循环利用的多机理湿式除尘设备的除尘方法，包括如下步骤：
步骤一、粉尘捕集
由除尘风筒上端的过滤入口引入含尘气体，控制同轴多环喷管喷水，含尘气体穿过同轴多环喷管喷出形成的水幕，粉尘与水滴相对运动产生撞击 。
步骤二、粉尘沉降
沿除尘风筒内壁流下的含尘水滴和由除尘风筒中心区域直接落下的含尘水滴分别通过环槽导流管和含尘浓水导流管引导至沉淀水箱底部，进入沉淀水箱底部含尘水中的粉尘在自身重力和惯性的作用下沉降。气液分流环槽与含尘浓水导流管避免了直接落入沉淀水箱中的含尘水未经分离直接进入溢流槽，且环槽导流管与含尘浓水导流管将含尘水滴直接引导至沉淀水箱底部，提高了分离效率。
步骤三、气水分离
经除尘风筒处理后的气体，由气液分流环槽与含尘浓水导流管上端口之间预留的气流通道绕流至外部较大的空间。含尘水滴沿除尘风筒内壁流入气液分流环槽，避免了大量含尘水滴与从气液分流环槽下部气流通道高速绕流气体的接触，从而减少了水滴被带走的几率，使气水分离简单、高效。
步骤四、粉尘排出
沉淀水箱底部沉降的粉尘经螺旋输料管结构的粉尘排出装置排出，水与粉尘在螺旋输料管内处于上下分层状态，螺旋输料管只排出粉尘，不排出水，将水通过回水通道引流至沉淀水箱后循环利用 。
优选的，所述的步骤一中，控制含尘气体由过滤入口沿除尘风筒内壁的切线方向进入，粉尘在自身重力和惯性的作用下沿除尘风筒内壁倾斜向下运动。
