下面通过具体实施例，并结合附图，对本发明的技术方案作进一步的具体描述：
实施例1
如图1至图4所示，一种旋风分离装置，包括内桶1，内桶1周面的切向方向设有进气口2，内桶1的顶部设有出气管3，还包括外桶5，内桶1设于外桶5中，内桶1的外壁为用于液固分离的过滤网4，所述内桶1的外壁与所述外桶5的内侧壁之间形成腔体6，所述腔体6中设置有用于将所述过滤网4上的固体吹落至内桶1所设中空腔体内的吹扫装置。在本实施例中，出气管3的一端伸出内桶1的外部，另一端伸入至内桶1的中部，将混有固体微粒与液体的气体由进气口2进入内桶1并形成回转气流，在离心作用下，液体穿过过滤网4进入外桶5中，并沿外桶5的内壁落至外桶5的底部，被过滤网4阻隔的固体颗粒大部分位于过滤网4的内侧并落至内桶1的底部，少部分附着在过滤网4上，吹扫装置可以将粘在过滤网4上的固体微粒逐步吹落至内桶1的底部；回转气流中的气体通过插入内桶1中的出气管3排出，进而实现对气液固三相混合物的分离。本发明结构简单，采用一套设备一次性实现气固液的三相分离，尤其吹扫装置解决了于 粘性颗粒快速堵塞滤孔而使过滤器快速失效以及高能耗的难题，节约了成本，达到了更好的旋风除尘以及气液固的分离，同时本装置中的内桶1和外桶5的底部均设置为锥形结构，这样可以方便本装置对液体以及固体微粒的收集。
其中，吹扫装置包括用于连通外接风机的进气11管以及喷气爪7，进气管11与喷气爪7相连通，喷气爪7上部为顶部开口的环状盒71，环状盒71与内桶1相套接并通过第一密封圈73转动密封，喷气爪7下部为若干均匀分布的向下伸展的喷气腿72，喷气腿72与环状盒71相连通，喷气腿72内侧设置有正对过滤网4的喷气孔18。在本实施例中，喷气腿72为空心结构，风机提供的喷气压强大于内筒气压，通过进气管11吹至环状盒71中，然后通过喷气腿72上的喷气孔18中吹出，将风吹至过滤网4上，进而将过滤网4上的粘性固体以及塞进过滤网4上的固体微粒吹至内桶1的底部，这样可以避免粘性固体颗粒堵塞过滤网4的过滤孔而致使过滤装置失效的问题。
另外，外桶5包括相连的顶盖51与环套52，顶盖51位于环状盒71的上方，环套52与环状盒71相套接并通过第二密封圈54转动密封，进气管11设于顶盖51上，进气管11的一端与环状盒71相连通，另一端与外接风机相连通；外桶5还包括外壳53以及底锥55，外壳53的上端安装在环套52上，外壳53的下端安装在底锥55上。在本实施例中，环套52的上下两部分结构外径不同并形成台阶，这样可以方便外壳52安装在环套52以及底锥55上。
另外，驱动装置包括安装在顶盖72上设有相连的电机21与变速箱24、设于电机21及其变速箱24输出轴上的齿轮22以及设于喷气爪7上部环状盒71内侧的齿圈23，所述电机21及其变速箱24通过啮合的齿轮22、齿圈23驱动环状盒71转动。在本实施例中，电机21通过固定轴25固定在外桶5的顶盖51上，外桶5固定不动，电机21通过变速箱24、齿轮22以及齿圈23带动环状盒71以及安装在环状盒71上的喷气腿72绕着内桶1旋转。
其中，喷气孔18为通风狭缝，喷气爪7设有通风狭缝的一侧面与过滤网4相贴合。在本实施例中，喷气腿72为空心结构，同时喷气腿72的顶部为开口结构，环状盒71的底部设置有与喷气腿72顶部的开口结构相对应的的通孔41，由进气管11中进入的强劲气流通过通孔41进入到空心的喷气腿72中，并从喷气腿72与过滤网4相贴合的通风狭缝中吹出，这样更方便进气管11中的强劲气流通过通风口将过滤网4上的固体微粒吹掉；本装置等间隔设置有三个喷气腿 72，喷气腿72喷气的一侧与过滤网4相贴合，在喷气腿72喷气吹扫时，这样可以使喷气爪7产生的各方向作用力相互抵消，进而使本旋风分离装置的运行更加平稳，此外，这样设置在保证回转气流中的液体可以进入到外桶5的前提下，通过旋转使喷气腿72中的强劲气流吹至过滤网4的各个部位，进而将过滤网4上的固体微粒吹至内桶1的底部，即使不能一次性将所有固体微粒吹至内桶1的底部，也可以使过滤网4上的固体颗粒逐步干燥并向下移动直至内桶1的底部。
另外，内桶1的底部设有第一出料管32，第一出料管32与内桶1相连通，第一出料管32的出料口设有第一翻料板33，第一翻料板33与第一出料管32通过弹性件相铰接。在本实施例中，当内桶1底部储存的固体微粒较少时，第一翻料板33将第一出料管32的管口封闭，随着固体颗粒的增加到一定重量时，第一翻料板33打开，固体颗粒顺着第一出料管32卸料到其它用于收集固体的装置中，过后又快速恢复关闭，使得整个旋风分离装置内气压平衡不被破坏。另外，外桶5的底部设有第二出料管34，第二出料管34与外桶5相连通，第二出料管34的出料口设有第二翻料板35，第二翻料板35与第二出料管34通过弹性件相铰接。在本实施例中，当外桶5底部储存的液体较少时，第二翻料板35将第二出料管34的管口封闭，随着液体的增加到一定重量时，第二翻料板35打开，液体顺着第二出料管34卸料到其它用于收集液体的装置中，过后又快速恢复关闭，使得整个旋风分离装置内气压平衡不被破坏。
其中，各喷气腿72的上端与环状盒71的底部相连通，下端通过法兰圈81安装在第一出料结构上并与其转动连接。在本实施例中，各喷气腿72的底端固定安装在法兰圈81上，法兰圈固定在第一出料管32上的轴承上，从而对喷气爪包括从上至下地固定，同时使驱动装置可以驱动喷气爪7绕着内桶1平稳转动。
另外，进气口2中设有用于喷淋气体的喷水环31。在本实施例中，喷水环31可以喷出水或者其它所需的雾状液体，喷水环31喷出的液体可以喷淋混有液固的气流，这样一方面可以除去气体中具有水溶性的有害成分，这部分有害成分随着液体进入外桶5中，雾状液体可以湿润固体微粒，这样可以使相近的固体微粒粘在一起，增大颗粒的体积，进一步避免固体微粒穿过过滤网4进入外桶5中，同时更好地阻止固体以微粒的形态被气体带出出气管3。
另外，环状盒71中套设在内桶1上的筒状结构上设有喷气缝17。在本实施例中，进气管11中的强劲气流还可以通过喷气缝17吹至过滤网4上，在电 机21带动环状盒71绕内桶1旋转时，喷气缝17配合喷气腿72一起对过滤网4进行喷扫，这样可以进一步保证吹扫装置对过滤网4吹扫的全面性，同时，环状盒71与固定喷气腿72的法兰圈81可以进一步限定喷气爪7的位置，保证过滤网4有效地过滤。
工作原理：
在本发明中，将混有固体微粒与液体的气体由进气口2进入内桶1并形成回转气流，在离心作用下，液体穿过过滤网4进入外桶5中，并沿外桶5的内壁落至外桶5的底部；被过滤网4阻隔的固体颗粒大部分位于过滤网4的内侧并落至内桶1的底部，少部分附着在过滤网4上，位于腔体6中的转动着的吹扫装置可以周期性地将粘在过滤网4上的固体微粒逐步吹落至内桶1的底部，回转气流中的气体通过内桶1顶部的出气管3排出，进而实现对气液固三相混合物的分离。本发明结构简单，采用一套设备一次性实现气固液的三相分离，尤其吹扫装置解决了于粘性颗粒快速堵塞过滤网44中的滤孔而使过滤器快速失效以及高能耗的难题，节约了成本，达到了更好的旋风除尘以及气液固的分离。
实施例2
如图5所示，一种旋风分离方法，包括以下步骤：
S1：将混有微粒与液体的气体沿内桶1的切向方向导入内桶1中并形成回转气流；
S2：通过过滤网4将步骤S1回转气流中的液体分离至设于内桶1外部的外桶5中；
S3：通过回转使步骤S2回转气流的微粒分离至内桶1或过滤网4上，并使回转气流中的气体通过设于内桶1上的出气口排出；
S4：利用吹扫装置将步骤S3中的过滤网4上的微粒吹落至内桶1中；
S5：内桶1底部第一出料管32的出料口上方积累固体后，第一翻料板33将被推动而卸料，过后又快速恢复关闭，使得整个旋风分离装置内气压平衡不被破坏；
S6：当外桶5底部的第二出料管34的出料口上方积累液体后，第二翻料板35将被推动而卸料，过后又快速恢复关闭，使得整个旋风分离装置内气压平衡不被破坏。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非 是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
