具体实施方式
以下将结合附图对本发明的较佳实施例进行详细说明,以便更清楚理解本发明的目的、特点和优点。应理解的是,附图所示的实施例并不是对本发明范围的限制,而只是为了说明本发明技术方案的实质精神。
在下文的描述中,出于说明各种公开的实施例的目的阐述了某些具体细节以提供对各种公开实施例的透彻理解。但是,相关领域技术人员将认识到可在无这些具体细节中的一个或多个细节的情况下来实践实施例。在其它情形下,与本申请相关联的熟知的装置、结构和技术可能并未详细地示出或描述从而避免不必要地混淆实施例的描述。
在整个说明书中对“一个实施例”或“一实施例”的提及表示结合实施例所描述的特定特点、结构或特征包括于至少一个实施例中。因此,在整个说明书的各个位置“在一个实施例中”或“在一实施例”中的出现无需全都指相同实施例。另外,特定特点、结构或特征可在一个或多个实施例中以任何方式组合。
在以下描述中,为了清楚展示本发明的结构及工作方式,将借助诸多方向性词语进行描述,但是应当将“前”、“后”、“左”、“右”、“外”、“内”、“向外”、“向内”、“上”、“下”等词语理解为方便用语,而不应当理解为限定性词语。
根据本发明的一个方面,提供一种电场单元,该电场单元具有沿轴向延伸的通道,环绕通道形成侧壁,侧壁设有供气体进入通道的进气孔和供气体排出通道的出气孔。
需要说明的是,气体不沿着通道的轴向方向流动,可以理解为,气体不沿着通道的轴向方向从通道的一端流向通道的另一端;气体是通过进气孔进入通道,再通过出气孔排出通道。
需要注意的是,上述电场单元可以作为电场装置的吸附极,电场装置的放电极放电电离,气体中颗粒物与带电离子结合后,使气体中的颗粒物获得电荷,带电荷的颗 粒物向吸附极移动,并沉积在吸附极,当气体以不平行于电场单元的侧壁的方向进气时,也就是说气体进入方向与电场内离子流方向不垂直,相比较气体进入方向与离子流方向垂直的电场,本发明增加了气体在电场中的停留时间,可以提高颗粒物的带电效率,更多的颗粒物沉积在吸附极,从而提高了除尘效率。
还需要注意的是,当进气孔的孔心与出气孔的孔心布置在与轴向垂直的不同平面上,可以使通道中的气体流向紊乱,进一步增加了气体在电场中的停留时间,增加近距离与放电极接触的频次,提高颗粒物带电效率和带电量;而且当气体形成旋风式流向时,有利于大颗粒的分离,综合以上两点,能够有效提高除尘效率。另外需要注意的是,多个侧壁中的至少一个侧壁沿通道方向延伸的中线上不设置进气孔或所述出气孔,可以使得中线位置上的面积不缺损,颗粒物带电后,直接吸附到吸附极中线附近位置,增加了颗粒物在吸附极上的吸附量,从而提高除尘效率。其中,所述颗粒物包括但不限于固体颗粒、液滴、附着有液体的固体颗粒、气溶胶、等离子态的固体颗粒或液滴等,也可以为细菌、真菌等微生物。
图1是本发明一个实施例的电场装置的立体示意图,电场装置20包括放电极209和吸附极200,吸附极200由电场吸附装置构成,在本实施例中,吸附极200也称之为电场吸附装置200。其中,电场吸附装置200包括十二个电场单元2000,十二个电场单元2000以左右相邻排布,相邻的电场单元2000共用一个侧壁,每个电场单元2000的通道被侧壁环绕成的与轴向方向垂直的截面为正三角形,在其他实施例中,电场吸附装置中的电场单元的数量不限于此,可以根据实际的需要净化的气体风量对电场单元的数量进行调整,而且,多个电场单元的排布方式可以是上、下、左、右、前、后任意方向进行相邻设置和/或不相邻设置。在本实施例中,为了便于生产加工,十二个电场单元的结构和形状均相同,然而,在其他实施例中,根据装置空间存放条件或其他因素,多个电场单元的结构、大小也可以不相同、也可以部分相同。
参照图1,以第一电场单元2100和第二电场单元2200的结构为例进行说明,其他电场单元的结构以此类推。第一电场单元2100具有沿轴向延伸的第一通道2110,所述轴向即与电场单元2100沿第一通道2110方向延伸的中心轴的方向相同,环绕第一通道2110形成侧壁2120,侧壁2120设有供气体进入通道2110的第一进气孔213和供气体排出通道的第一出气孔214,第一进气孔213和第一出气孔214的数量为多个,较佳地,多个第一进气孔213和多个第一出气孔214孔径大小相同,多个第一进气孔213沿轴向均匀布置成一列于第一侧壁2121上,多个第一出气孔214沿轴向均匀布置成一列于第二侧壁2122上,第三侧壁2123上未设置进气孔或出气孔,第一进气孔213的孔心与第一出气孔214的孔心布置在与轴向垂直的不同平面上。第一电场单元2100和第二吸附单元2200共用第二侧壁2122,第二侧壁2122的两个表面分别面对第一电场单元2100的第一通道2110和第二电场单元2200的第二通道2210,也就是说,以第一吸附单元2100的第二侧壁2122上的第一出气孔214作为第二吸附单元2200的第二侧壁2122的第二进气孔,以保证气体从第一电场单元2100直接进入第二电场单元2200,第二吸附单元2200的第四侧壁2222上开设多个沿轴向均匀布置成一列的第二出气孔224,第二吸附单元2200的第五侧壁2223上没有开设进气孔和/或出气孔。
参照图1,每个放电极209设置于与之对应的电场单元2000的通道内,由于每个电场单元2000的通道被侧壁环绕成的与轴向方向垂直的截面为正三角形,放电极209优选平行于通道的侧壁设置并经过与之对应的电场单元2000的截面内切圆的圆心,此处的放电效率最高。需要说明的是,这里的截面指的是电场单元2000的垂直于通道的轴向方向的截面。例如,第一放电极219设置于第一电场单元2100的通道内,且优选 平行于通道的侧壁设置并经过第一电场单元2100的截面内切圆的圆心。其他放电极与电场单元的关系与此类似,此处不再详述。
继续参照图1,所有电场单元2000与电源的同一极电连接,所有放电极209与电源的另一极电连接,比如,以第一电场单元2100和第二电场单元2200为例,第一电场单元2100与电源的阳极电性连接,而第一放电极219与电源的阴极电性连接;以及第二电场单元2200与电源的阳极电性连接,而第二放电极229与电源的阴极电性连接。第一电场单元2100与第一放电极219形成第一电场,第二电场单元2200与第二放电极229形成第二电场。
然而,在其他实施例中,多个电场单元可以分为两组,两组电场单元排成两排以上的形式组合在一起,每一排的电场单元在同一组中,第一组电场单元与电源的阳极电性连接、与之对应的第一组放电极与电源的阴极电性连接;第二组电场单元与电源的阴极电性连接、与之对应的第二组放电极与电源的阳极电性连接。当气流先后经过第一组电场单元和第一组放电极形成的电场与第二组电场单元和第二组放电极形成的电场时,分别使气体中的颗粒物获得负电荷和正电荷,使气体中带负电荷的颗粒物被沉积于第一组电场单元上,气体中带正电荷的颗粒物被沉积于第二组电场单元上,提高了除尘效率。
参照图1,以第一电场单元2100和第二电场单元2200的气体走向为例,其他电场单元的气体走向与次类似,不再详述。由于第一电场中第一进气孔213与第一出气孔214的孔心布置在与轴向垂直的不同平面上,第二电场中第二进气孔与第二出气孔224的孔心布置在与轴向垂直的不同平面上,气体先后经过第一电场和第二电场的气体流向紊乱,进一步增加了气体在两个电场中的停留时间,增加近距离与第一放电极219和第二放电极229接触的频次,距离放电极209越近的地方,气体电离效率越高,提高颗粒物带电效率和带电量;而且当气体形成旋风式流向时,有利于大颗粒的分离,综合以上两点,有效提高了除尘效率。
在其他实施例中,也可以在第二电场单元2200的第五侧壁2223上开设进气孔,那么第二电场单元2200和第三电场单元2300的气流相通,气体可以从第三电场单元2300流向第二电场单元2200。然而,在其他实施例中,每个电场单元的侧壁都可以开设进气孔或出气孔,导致每个电场单元的气体可以来源于多个相邻的电场单元,也可以流向多个相邻的电场单元,气体流向高度紊乱,经过放电极附近的气流变多,增加了气体中的颗粒物带电效率和带电量,提高了除尘效率。
图2A是本发明的一个实施例的电场单元的立体示意图,所述电场单元710具有沿轴向延伸的通道711,环绕通道711形成侧壁712,侧壁712设有供气体进入通道711的进气孔713和供气体排出通道711的出气孔714,进气孔713的孔心与出气孔714的孔心布置在与轴向垂直的不同平面上。
参照图2A,电场单元710具有沿轴向延伸的通道711,所述轴向即与电场单元710沿通道方向延伸的中心轴的方向相同。环绕通道711形成三个侧壁712,包括第一侧壁7121、第二侧壁7122和第三侧壁7123,第一侧壁7121、第二侧壁7122和第三侧壁7123沿电场单元710的轴向长度相等,通道711被第一侧壁7121、第二侧壁7122和第三侧壁7123环绕成的截面优选为正三角形,所述截面是指与轴向方向垂直的截面。然而,在其他实施例中,电场单元也可以包括三个以上侧壁,例如,电场单元可以包括三个、四个、五个或六个、甚至更多个侧壁,通道被侧壁环绕成的截面可以是三边形、四边形、五边形、或六边形、以及其他多边形。较佳地,通道被侧壁环绕成的截面为正多边形;电场单元也可以只包括一个侧壁,也就是说,通道被侧壁环绕成的截面为圆形或椭圆形;优选地,通道被侧壁环绕成的正多边形的截面的内角角度是 数字360的整除数,这有利于多个电场单元在一个平面内360度无缝拼接,简化制造工艺;更优选地,通道被侧壁环绕呈的截面为正三角形或正六边形。
在一个实施例中,第一侧壁7121、第二侧壁7122和第三侧壁7123具有侧壁主体和从所述侧壁主体沿垂直于所述通道的两端分别弯折形成的折边部,所述连接件设置于相邻两个侧壁的折边部,以将相邻两个侧壁固定连接。由于使用连接件连接的侧壁不仅可以做到标准化、批量化的生产,加工方便,效率高,而且连接件连接具有装配简单,可拆卸便于包装运输的优点。
参照图2A,第一侧壁7121具有第一侧壁主体71211和从第一侧壁主体71211的两端分别弯折形成的第一侧壁左折边部71212和第一侧壁右折边部71213,第二侧壁7122具有第二侧壁主体71221和从第二侧壁主体71221的两端分别弯折形成的第二侧壁左折边部71222和第二侧壁右折边部71223,第三侧壁7123具有第三侧壁主体71231和从第三侧壁主体71231的两端分别弯折形成的第三侧壁左折边部71232和第三侧壁右折边部71233。其中,第一侧壁左折边部71212和第一侧壁右折边部71213相互平行,第二侧壁左折边部71222和第二侧壁右折边部71223相互平行,第三侧壁左折边部71232和第三侧壁右折边部71233相互平行且垂直于第三侧壁主体71231。需要说明的是,此处的“左”和“右”仅仅是为了将两个折边部区别开来,不构成对方位的限定。
继续参照图2A,每一个侧壁的折边部都沿通道711的延伸方向延伸,以及相邻两个侧壁的折边部对齐配合并通过连接件连接,从而通过折边部和连接件将相邻的两个侧壁固定连接。例如,各个折边部上分别设置多个沿通道的延伸方向排列的通孔718,连接件穿设于通孔718内并固定,从而将相邻的侧壁固定连接。较佳地,各个折边部沿通道的两个端部均分别设有通孔718。较佳地,在各个折边部端部均设有通孔连接件可以是铆钉、螺钉等,相邻的两个侧壁通过铆钉连接、螺栓连接、螺钉连接等实现连接。在本施例中,相邻的两个侧壁通过铆钉依次铆接。
参照图2A、图3,在本实施例中,第一侧壁7121的第一侧壁右折边部71213与第二侧壁7122的第二侧壁右折边部71223通过铆钉99铆接并形成连接顶端。第二侧壁7122的左折边部71222与第三侧壁7123的左折边部71232通过铆钉99铆接并形成第一连接底端。第一侧壁7121的左折边部71212与第三侧壁7123的右折边部71233通过铆钉99铆接并形成第二连接底端。
在一个实施例中,参照图2A,侧壁712设有供气体进入通道711的进气孔713和供气体排出通道711的出气孔714,进气孔713和出气孔714优选分别布置于不同的侧壁上,例如,进气孔713布置在第三侧壁7123上,出气孔714包括第一出气孔7141和第二出气孔7142,第一出气孔7141布置于第一侧壁7121上,第二出气孔7142布置于第二侧壁7122上。在本实施例中,电场单元710的三个侧壁都布置有进气孔713或出气孔714,然而,需要理解的是,在其他实施例中,进气孔和/或出气孔可以布置于电场单元的部分侧壁上,比如,进气孔713布置在第三侧壁7123上,第一出气孔7141布置于第一侧壁7121上,第二侧壁7122上不再布置第二出气孔7142,或进气孔713布置在第三侧壁7123上,第二出气孔7142布置于第二侧壁7122上,第一侧壁7121上不再布置第一出气孔7141。此外,在其他实施例中,进气孔和出气孔也可以布置于同一个侧壁的不同位置,例如,进气孔布置于侧壁的上部、出气孔布置于侧壁的下部,或者进气孔布置于侧壁的左侧、出气孔布置于侧壁的右侧。本领域技术人员需要理解的是,进气孔和出气孔的位置不限于上述列举的方式。
在一个实施例中,参见图2A,多个侧壁中的至少一个侧壁沿通道方向延伸的中线上不设置进气孔或出气孔,该侧壁上中线与通道中心线的距离是最短的。较佳地,每 一个侧壁沿通道方向延伸的中线两侧2-50mm范围内不设置所述进气孔或所述出气孔。
参照图2A,设置进气孔的侧壁,例如第三侧壁7123设置有多个进气孔713;设置出气孔的侧壁,例如第一侧壁7121和第二侧壁7122,设置有多个出气孔714。多个进气孔713沿轴向均匀布置成两列于第三侧壁7123上,多个第一出气孔7141沿轴向均匀布置成两列于第一侧壁7121上,多个第二出气孔7142沿轴向均匀布置成两列于第二侧壁7122上。较佳地,两列进气孔和/或出气孔分别设置在侧壁中线的两侧,例如,多个第一进气孔7141布置成两列并设置于第一侧壁7121的中线一定距离的两侧,并优选将两列第一进气孔7141布置对称于第一侧壁7121的中线进行布置在其他实施例中,多个进气孔和/或出气孔也可以沿轴向布置成一列或一列以上任意列数,进气孔和/或出气孔也可以以非均匀的形式布置于侧壁上。本实施例中,多个进气孔713沿轴向从第三侧壁7123的一端布置到第三侧壁7123的另一端,多个第一出气孔7141沿轴向从第一侧壁7121的一端布置到第一侧壁7121的另一端,多个第二出气孔7142沿轴向从第二侧壁7122的一端布置到第二侧壁7122的另一端,在其他实施例中,可以根据实际进气或出气的需要,将进气孔或出气孔也可以沿轴向分布于侧壁的一部分。
图2B是图2A的电场单元的C向视图,如图2B所示,进气孔713的孔心与出气孔714的孔心布置在与轴向垂直的不同平面上,也就是说,进气孔713的孔心与出气孔714的孔心的连线与轴向不垂直。该结构使得气体以不平行于电场单元的侧壁的方向进气时,气体通过进气孔713进入电场单元710的内部通道,气体不能通过出气孔直接排出,使得气体流向紊乱,增加在通道内的停留时间,甚至形成旋风式气体流向,再通过出气孔714排出电场单元710。本实施例中,进气孔713的孔心与第一出气孔7141和第二出气孔7142的孔心布置在与轴向垂直的不同平面上,第一出气孔7141和第二出气孔7142的孔心可以布置在与轴向垂直的相同平面上、也可以布置在与轴向垂直的不同平面上。当进气孔713和出气孔714的数量为多个时,优选地,任意一个进气孔的孔心与任意一个出气孔的孔心布置在与轴向垂直的不同平面上。
参照图2B,进气孔713和出气孔714为直径相同的圆形孔。然而,在其他实施例中,进气孔和出气孔可以是椭圆形孔、三角形孔、四边形孔或五边形孔;进气孔和出气孔的直径也可以不同,但是需要保证气体不能无阻挡地通过出气孔直接排出,即如果将两个侧壁重叠在一起,进气孔和出气孔不会完全重叠或一个进气孔/出气孔完全包含另一个出气孔或进气孔的情况,从而保证气体在流动时会遇到阻挡,使得气流在进气孔流入并从出气孔流出时,改变了方向并在通道内形成旋风路径后,再通过出气孔排出电场单元。
在一个实施例中,一个侧壁上的进气孔或出气孔的总面积与该侧壁总面积之比小于或等于一定数值。发明人经过大量实验和深入研究后意外发现,将一个侧壁上的进气孔或出气孔的总面积设置成该侧壁总面积之比小于或等于49%时,较佳地,在40%-49%区间内,更佳地,等于49%,既增加了通风量,又可以最大限度保证侧壁的强度和刚性。
在一个实施例中,侧壁采用导电材料制成,例如采用含有不锈钢和/或铝的材料制成,较佳地,采用铝材料具有能耗小的优点。
图3是本发明的一个实施例的电场装置的俯视剖面示意图,电场装置700包括放电极719和吸附极710,吸附极710由电场单元构成,在本实施例中,吸附极710也可以称之为电场单元710,电场单元与上文相同之处不再赘述,本实施例仅对不同之处加以叙述。
如图3所示,电场单元710的通道711内设有放电极719,本实施例中,通道711被侧壁环绕成的与轴向方向垂直的截面为正三角形,放电极719优选平行于通道的侧 壁设置并经过截面内切圆的圆心,此处的放电效率最高。然而,在其他实施例中,通道被侧壁环绕成的与轴向方向垂直的截面可以为其他多边形,放电极平行于通道的侧壁设置并经过通道的中心线,所述中心线为沿通道轴向方向延伸并经过多边形截面中点的线,例如,通道被侧壁环绕成的与轴向方向垂直的截面为矩形时,中心线为沿通道轴向方向延伸并经过矩形截面长边对称轴与短边对称轴的交点的线。通道被侧壁环绕成的与轴向方向垂直的截面为三角形时,中心线为沿通道轴向方向延伸并经过三角形截面的角平分线的交点的线。优选地,通道被侧壁环绕成的与轴向方向垂直的截面为正多边形时,放电极平行于通道的侧壁设置并经过截面内切圆的圆心。本领域技术人员可以理解的是,由于实际加工条件的限制,放电极可能布置于稍微偏离通道的中心线或截面内切圆的圆心处。
本实施例中,放电极719为细长状针状导体,在其他实施例中,放电极也可以为多角状、毛刺状、螺纹杆状或柱状导体。本实施例中,放电极719的直径为0.1-10mm,较佳地,放电极719的直径为0.2-5mm。
在一个实施例中,放电极719呈细长条状并采用304不锈钢、钛、钨、铱金中的任意一种制成,较佳地,放电极采用铱金制成。
参照图3,电场单元710与电源的一个电极电性连接,放电极719与电源的另一个电极电性连接,电场单元710和放电极719形成有源电场,优选地,电场单元710与电源的阳极电性连接,放电极719与电源的阴极电性连接,即电场单元710为阳极,放电极719为阴极。然而,在其他实施例中,电场单元710也可以与电源的阴极电性连接,放电极719与电源的阳极电性连接,即电场单元710为阴极,放电极719为阳极。当电场单元710与电源的阳极电性连接,放电极719与电源的阴极电性连接时,气体以不平行于电场单元710的侧壁的方向进气,放电极719放电并电离,使气体中的颗粒物获得负电荷,带负电的颗粒物向电场单元710移动,并沉积在电场单元710上。当电场单元710侧壁上的进气孔的孔心与出气孔的孔心布置在与轴向垂直的不同平面上时,可以使通道711中的气体流向紊乱,进一步增加了气体在通道711中的停留时间,增加近距离与放电极719接触的频次,距离放电极719越近的地方,气体电离效率越高,从而提高颗粒物带电效率和带电量;而且当气体形成旋风式流向时,有利于大颗粒的分离,综合以上两点,有效提高了除尘效率。
图4A是本发明的一个实施例的电场装置的立体示意图,电场装置80包括放电极和吸附极。在本实施例中,吸附极和放电极与上文相同之处不再赘述,本实施例仅对不同之处加以叙述。
参照图4A,吸附极由电场吸附装置800构成。电场吸附装置800包括八个电场单元,分别是第一电场单元810、第二电场单元820、第三电场单元830、第四电场单元840、第五电场单元850、第六电场单元860、第七电场单元870和第八电场单元880,八个电场单元以左右相邻排布,相邻的电场单元共用一个侧壁,每个电场单元的通道被侧壁环绕成的与轴向方向垂直的截面为正三角形,在其他实施例中,电场吸附装置中的电场单元的数量不限于此,可以根据实际的需要净化的气体风量对电场单元的数量进行调整,而且,多个电场单元的排布方式可以是上、下、左、右、前、后任意方向进行相邻设置和/或不相邻设置。在本实施例中,为了便于生产加工,八个电场单元的结构和形状均相同,然而,在其他实施例中,根据装置空间存放条件或其他因素,多个电场单元的结构、结构、大小也可以不相同、也可以部分相同。
参照图4A,放电极809包括第一放电极819、第二放电极829、第三放电极839、第四放电极849、第五放电极859、第六放电极869、第七放电极879、第八放电极889,每个放电极设置于与之对应的电场单元的通道内,由于每个电场单元的通道被侧壁环 绕成的与轴向方向垂直的截面为正三角形,放电极809优选平行于通道的侧壁设置并经过与之对应的电场单元截面内切圆的圆心,此处的放电效率最高。例如,第一放电极819设置于第一电场单元810的通道内,且优选平行于通道的侧壁设置并经过第一电场单元810截面内切圆的圆心,以此类推其他放电极与电场单元的关系。
参照图4A,以第一电场单元810和第二电场单元820的结构为例进行说明,其他电场单元的结构以此类推。第一电场单元810包括具有沿轴向延伸的第一通道811,环绕第一通道811形成侧壁812,侧壁812上设有供气体进入通道811的第一进气孔813和供气体排出第一通道811的第一出气孔814,第一进气孔813和第一出气孔814的数量为多个,多个第一进气孔813沿轴向均匀布置成两列于第一侧壁8121上,多个第一出气孔814沿轴向均匀布置成两列于第二侧壁8122上,没有进气孔或出气孔分布于第三侧壁8123上,第一进气孔813的孔心与第一出气孔814的孔心布置在与轴向垂直的不同平面上。第一电场单元810和第二电场单元810共用第二侧壁8122,第二侧壁8122的两个表面分别面对第一电场单元810的第一通道811和第二电场单元820的第二通道821,也就是说,以第一电场单元810的第二侧壁8122上的第一出气孔814作为第二电场单元820的第二侧壁8122的第二进气孔,以保证气体从第一电场单元810直接进入第二电场单元820,第二电场单元820的第四侧壁8222上开设多个沿轴向均匀布置成两列的第二出气孔824,第二电场单元820的第五侧壁8223上没有开设进气孔和/或出气孔。
参照图4A,本实施例中,所有电场单元与电源的同一极进行电连接,所有放电极与电源的另一极进行电连接,比如,以第一电场单元810和第二电场单元820为例,第一电场单元810与电源的阳极电性连接、第一放电极819与电源的阴极电性连接;第二电场单元820与电源的阳极电性连接、第二放电极829与电源的阴极电性连接。第一电场单元810与第一放电极819形成第一电场,第二电场单元820与第二放电极829形成第二电场。然而,在其他实施例中,多个电场单元分为两组,两组电场单元排成两排以上的形式组合在一起,每一排的电场单元在同一组中,第一组电场单元与电源的阳极电性连接、与之对应的第一组放电极与电源的阴极电性连接;第二组电场单元与电源的阴极电性连接、与之对应的第二组放电极与电源的阳极电性连接。当气流先后经过第一组电场单元和第一组放电极形成的电场和第二组电场单元和第二组放电极形成的电场时,分别使气体中的颗粒物获得负电荷和正电荷,使气体中带负电荷的颗粒物被沉积于第一组电场单元上,气体中易与正电荷的颗粒物被沉积于第二组电场单元上,提高了除尘效率。
参照图4A,以第一电场单元810和第二电场单元820的气体走向为例,其他电场单元的气体走向以此类推。气体通过第一进气孔813进入第一电场,而后通过第一出气孔814进入第二电场,最后通过第二出气孔824排出。由于第一进气孔813与第一出气孔814的孔心布置在与轴向垂直的不同平面上且第二进气孔(在本实施例中第二进气孔为第一出气孔814)与第二出气孔824的孔心布置在与轴向垂直的不同平面上,气体先后经过第一电场和第二电场的气体流向紊乱,进一步增加了气体在两个电场中的停留时间,增加近距离与第一放电极819和第二放电极829接触的频次,距离放电极809越近的地方,气体电离效率越高,提高颗粒物带电效率和带电量;而且当气体形成旋风式流向时,有利于大颗粒的分离,综合以上两点,有效提高了除尘效率。在其他实施例中,第二电场单元820的第五侧壁8223上开设进气孔,那么第二电场单元820和第三电场单元830的气流相通,气体可以从第三电场单元830流向第二电场单元820。然而,在其他实施例中,每个电场单元的侧壁都可以开设进气孔或出气孔,导致每个电场单元的气体可以来源于多个相邻的电场单元,也可以流向多个相邻的电 场单元,气体流向高度紊乱,经过放电极附近的气流变多,增加了气体中的颗粒物带电效率和带电量,提高了除尘效率。
图5是包括顶板和地板的电场装置的主视示意图,电场装置80还包括顶板81和底板82,顶板81和底板82分别连接电场吸附装置800的两端,也就是说分别连接电场吸附装置80中每一个电场单元的两端,并对两端进行密封,以保证气体只从每一个电场单元的进气孔或出气孔进出。需要说明的是,顶板81和底板82只是为了描述上的方便,并不旨在限制其方位,也就是说,顶部81并不需要位于顶部,底板82也不需要位于底部,具体可以根据电场装置80的摆放方位设置于电场吸附装置800的两端,以对每一个电场单元的通道进行密封。
图6是本发明的一个实施例的电场单元组件的剖面分解示意图,电场单元组件900包括电场单元910和辅助吸附机构920,电场单元910具有沿轴向延伸的通道911,环绕通道911形成侧壁912,侧壁912设有供气体进入通道的进气孔和供气体排出通道的出气孔,辅助吸附机构920具有多孔结构且布置于电场单元910的侧壁912的至少一部分的一侧,所述至少一部分设有进气孔和/或出气孔。电场单元与上文相同之处不再赘述,本实施例仅对不同之处加以叙述。
参照图6,电场单元910的侧壁912包括侧壁的内表面9121和侧壁的外表面9122,在本实施例中,辅助吸附机构920优选布置于电场单元910设有进气孔和/或出气孔的侧壁912的全部外表面9122的一侧,气体以不平行于电场单元910的侧壁912的方式通过,多孔结构的辅助吸附机构920可以通过物理过滤的方式在进气端和出气端过滤掉一部分气体中的颗粒,而在其他实施例中,辅助吸附机构也可以布置于电场单元的设有进气孔和/或出气孔侧壁的内表面和/或外表面的一部分的一侧。在本实施例中,辅助吸附机构920与电场单元910之间具有间隙,优选地,辅助吸附机构920与电场单元910之间具有小于或等于50mm的距离,在该距离空间中的气体会再次混合,混合后的气体进而通过电场单元910或辅助吸附机构920进行颗粒去除。在辅助吸附机构920与电场单元910之间的一定距离范围之内,随辅助吸附机构920与电场单元910的距离增加,辅助吸附机构910的带电荷量随之增加。在其他实施例中,辅助吸附机构920以胶粘的方式贴合于电场单元910的侧壁912的全部外表面9122,所述贴合可以理解为辅助吸附机构920与电场单元910之间理论上没有间隙,在其他实施例中,贴合方式也可以选自榫卯固定、铆钉固定或其他的机械固定方式,其中榫卯固定可以是,先将辅助吸附机构固定在框架上,再将框架与电场单元进行榫卯固定,然而,本领域技术人员可以理解的是,由于实际加工条件的限制,辅助吸附机构920贴合于电场单元910的侧壁912时可能存在一定间隙,该间隙可以忽略不计。
参照图6,在本实施例中,辅助吸附机构920由60目的聚四氟乙烯薄膜构成,由于聚四氟乙烯是驻极材料,当电场对驻极材料进行驻极充电后,驻极材料自身的驻极电场可以对带电的颗粒物有静电吸附作用,而且当电场突然消失时,驻极电场也不会消失,还可以继续进行除尘。在其他实施例中,辅助吸附机构的孔径也可以选自40目-100目中的一个或多个,孔径越细,气体的风阻越大,能耗越大,优选地,辅助吸附机构的孔径也可以选自40目-80目中的一个或多个;也可以是多层薄膜组合而成,且多孔结构相互交叠贯通。在其他实施例中,辅助吸附机构的材料可以选自导电材料或驻极材料中的一种或多种,其中导电材料可以选自金属或合金中的一种或多种,驻极材料可以选自具有驻极性能的无机化合物和/或具有驻极性能的有机化合物,所述无机化合物选自二氧化硅、钛酸钡、锆钛酸铅、氧化锌、氧化钽、氧化铝、氧化钛、氮化硅中的一种或多种组合,所述有机化合物选自氟碳聚合物、聚碳酸酯、聚丙烯、聚乙烯、聚氯乙烯、天然蜡、树脂、松香中的一种或多种组合,所述氟碳聚合物选自聚 四氟乙烯、聚偏氟乙烯、聚全氟乙丙烯、可溶性聚全氟乙丙烯、可溶性聚四氟乙烯中的一种或多种组合。

本发明的一个实施例提供一种电场装置,包括放电极和吸附极,吸附极由上述实施例中所述的电场吸附组件构成,电场吸附组件与上文相同之处不再赘述,本实施例仅对不同之处加以叙述。放电极可以由细长状或平板状导体构成,并布置于平板状吸附极的一侧,当放电极为平板状导体时,放电极的侧壁可以设有多个气孔以便气体的流通。在其他实施例中,吸附极也可以由上述实施例中电场单元的通道被侧壁环绕成的与轴向方向垂直的截面为多边形的电场单元组件构成,放电极平行于通道的侧壁设置并经过通道的中心线,所述中心线为沿通道轴向方向延伸并经过多边形截面中点的线,例如,通道被侧壁环绕成的与轴向方向垂直的截面为矩形时,中心线为沿通道轴向方向延伸并经过矩形截面长边对称轴与短边对称轴的交点的线;通道被侧壁环绕成的与轴向方向垂直的截面为三角形时,中心线为沿通道轴向方向延伸并经过三角形截面的角平分线的交点的线;优选地,通道被侧壁环绕成的与轴向方向垂直的截面为正多边形时,放电极平行于通道的侧壁设置并经过截面内切圆的圆心,此处的放电效率最高。
吸附极与电源的一极电性连接,放电极与电源的另一极电性连接。优选地,吸附极与电源的阳极电性连接,放电极与电源的阴极电性连接,吸附极和放电极形成电场,气体以不平行于吸附极的侧壁的方向进气,气体中的一部分颗粒物在进入电场前被布置在设有进气口侧壁的一侧的辅助吸附机构过滤,进入电场中的颗粒物由于电离放电而获得负电荷,带负电的颗粒物向吸附极移动,并沉积在吸附极上,没有被电场吸附 的颗粒物在离开电场后,也可以被布置在设有出气口侧壁的一侧的辅助吸附机构过滤,提高了除尘效率。当辅助吸附机构由驻极材料构成时,当电场对驻极材料进行驻极充电后,驻极材料自身的驻极电场可以对带电的颗粒物有静电吸附作用,而且电场突然消失时,驻极电场不会消失,也可以继续进行除尘。
本发明的一个实施例提供一种电场装置,包括放电极和吸附极,吸附极由上述实施例中所述的电场吸附装置构成,电场吸附装置和电场装置与上文相同之处不再赘述,本实施例仅对不同之处加以叙述。放电极设于电场吸附装置中每一个电场单元的通道内,优选地,通道被侧壁环绕成的与轴向方向垂直的截面为正多边形时,放电极平行于通道的侧壁设置并经过截面内切圆的圆心,此处的放电效率最高。当辅助吸附机构的材料为60目的聚四氟乙烯时,多孔材料的辅助吸附机构可以通过物理过滤的方式在进气端和出气端过滤掉一部分气体中的颗粒,且电场对驻极材料进行驻极充电后,驻极材料自身的驻极电场可以对带电的颗粒物有静电吸附作用,相比没有辅助吸附机构的情况下,除尘效率提高了10-20%。由于聚四氟乙烯是驻极材料,在有源电场突然消失时,辅助吸附机构的驻极电场也可以进行除尘,通过实验可知,当电场吸附装置的有源电场突然消失时,仅通过辅助吸附机构进行除尘的除尘效率可达30%。
在一个实施例中,参照图4B,电场吸附装置800由多个电场单元通过连接件连接形成。在本实施例中,电场吸附装置800由八个电场单元连接形成。具体地,电场吸附装置800整体上由两排电场单元构成,为了描述方便,以图4B所示的方向为参考,将侧壁面向下部的一排称为第一排,将侧壁面向上部的一排称为第二排。其中,第一排由大小结构均相同的第一电场单元810、第三电场单元830、第五电场单元850以及第七电场单元870通过其各自位于底部的侧壁依次连接形成,其通道的轴线相互平行且在同一平面上。第二排由大小结构相同的第二电场单元820、第四电场单元840、第六电场单元860以及第八电场单元880通过其各自位于顶部的侧壁依次连接形成。具体地,在本实施例中,第一电场单元810、第三电场单元830、第五电场单元850以及第七电场单元870的各自位于底部的侧壁都设有折边部,每相邻两个电场单元的位于底部的侧壁上的折边部相互对准,通过将连接件连接于折边部上,从而将相邻两个电场单元固定连接,例如,通过利用铆钉将相邻两个电场单元的折边部铆接,以将相邻两个电场单元固定连接。利用铆钉铆接,不仅便于加工。而且密封性好,铆接不仅使得相互连接的侧壁之间密封性好,而且铆钉在铆接时会在铆钉孔内膨胀,使得铆钉与孔之间也具有高密封的性能。类似地,第二电场单元820、第四电场单元840、第六电场单元860以及第八电场单元880位于顶部的侧壁也都设有折边部,相邻两个电场单元的位于顶部的折边部相互对准,通过将连接件连接于折边部上,从而将相邻两个电场单元固定连接。具体地,以第一排的第一电场单元810、第三电场单元830和第五电场单元850的连接方式为例说明相邻的电场单元的连接方式。第三电场单元830的底部侧壁设有向下弯折的第一折边部891,第一电场单元810的底部侧壁设有向下弯折的第二折边部892,第一折边部891和第二折边部892相互对齐,通过将连接件穿设于第一折边部891和第二折边部892以将第一电场单元810和第三电场单元830固定连接,第三电场单元830的底部侧壁设有向下弯折的第二折边部893,第五电场单元850底部侧壁设有向下弯折的第一折边部894,通过将连接件穿设于第一折边部894和第二折边部893以将第三电场单元和第五电场单元固定连接。在本实施例中,多个电场单元的各自的第一折边部和相邻单元的第二折边部优选通过铆钉铆接。第五电场单元850与第七电场单元870的连接方式与次类似,不再详述。
继续参照图4B,在本实施例中,第一电场单元810与第二电场单元820共用第二侧壁8122,也就是说,第二侧壁8122的两侧分别面对第一电场单元810的通道和第 二电场单元820的通道。第二侧壁8122的上端和下端分别设有上折边部895和下折边部896,上折边部895和下折边部896分别向不同的方向弯折,上折边部895的两侧分别与第一电场单元810的第三侧壁8123和第二电场单元820的第四侧壁8222的折边部对齐,并通过诸如铆钉的连接件固定连接。第二电场单元820的第四侧壁8222分别连接第一电场单元810和第三电场单元830,第四侧壁8222、第二侧壁8122以及第五侧壁8223构成第二电场单元820。
类似地,多个电场单元通过上述方式实现连接并形成电场吸附装置800。需要说明的是,在图4B所示的实施例中,每一个电场单元的每一个侧壁垂直于轴向的两端都设有折边部,同一个电场单元通过相邻侧壁的折边部配合,然后通过诸如铆钉铆接的方式实现固定连接,不同电场单元之间通过共用一块侧壁并将各自的另一块侧壁与共用侧壁固定连接实现连接,例如,第一电场单元810和第二电场单元820共用的第二侧壁8122与第一电场单元810的第三侧壁8123和第二电场单元820的第四侧壁8222同时固定连接。
需要说明的是,在图4B所示的实施例中,位于顶部的侧壁(例如第四侧壁8222)以及位于底部的侧壁(例如第一侧壁8121)的折边部大致沿与其所在的侧壁的主体部分垂直的方向弯折,而连接顶部的侧壁和底部的侧壁的位于中间的侧壁(例如第二侧壁8122)的折边部大致沿与其所在的侧壁的主体部分呈120度方向弯折。如此布置,可以方便电场吸附装置的平稳放置,并便于多层叠加放置。
图9A示出本发明一个实施例的电场吸附装置1100。参照图9A,电场吸附装置1100包括12个相同的电场单元,从左至右分别为第二电场单元620、第一电场单元610、第三电场单元630、第四电场单元640、第五电场单元650、第六电场单元660、第七电场单元670、第八电场单元680、第九电场单元690、第十电场单元691、第十一电场单元692、第十二电场单元693。12个相同的电场单元左右相邻排布,相邻的电场单元共用一个侧壁,每个电场单元的通道被侧壁环绕成的与轴向方向垂直的截面为正六边形,在其他实施例中,电场吸附装置中的电场单元的数量不限于此,可以根据实际的需要净化的气体风量对电场单元的数量进行调整,而且,多个电场单元的排布方式可以是上、下、左、右、前、后任意方向进行相邻设置和/或不相邻设置。在本实施例中,为了便于生产加工,十二个电场单元的结构和形状均相同,然而,在其他实施例中,根据装置空间存放条件或其他因素,多个电场单元的结构、结构、大小也可以不相同、也可以部分相同。
图9B是图9A的俯视图,参照图9B,本实施例中,第一电场单元610与第二电场单元620、第三电场单元630分别相邻设置。第一电场单元610由第一侧壁611、第二侧壁612、第三侧壁613、第四侧壁614、第五侧壁615、第六侧壁616围合而成,其横截面为正六边形。每个侧壁上均设有多个进气孔和/或出气孔。第一电场单元610与第二电场单元620共用第一电场单元610的第一侧壁613,第一电场单元610与第三电场单元630共用第一电场单元610的第五侧壁615。
在图9A和9B所示的实施例中,每一个电场单元的每一个侧壁沿通道方向延伸的中线都不设置进气孔或出气孔。具体地,以第一电场单元610为例进行说明,第一电场单元610的每一个侧壁的中线617上都不设置进气孔或出气孔,从而使得侧壁中线的位置形成积尘部分。当电场单元的通道的中心线设置放电极时,放电极与侧壁的中线之间的距离是放电极与侧壁之间的最短距离,从而该部分的吸尘效率最高,可以实现最好的吸尘效果。
需要说明的是,虽然图9A所示的实施例中,每一个电场单元的每一个侧壁的中线都不设进气孔或出气孔,然而,也可以仅仅在一个或多个电场单元的其中一个或多 个侧壁的中线部分不设置进气孔或出气孔,这些情况虽然效果没有图9A所示的实施例的优异,但是也具有一定的技术效果,与在中线位置设置进气孔或出气孔的方案相比,中线都不设进气孔或出气孔可以实现更高效率的积尘。
此外,还需要说明的是,本发明中的中线指的是侧壁上沿通道方向延伸的中线,中线与中线所在的侧壁垂直于通道的两端的距离相等。
图10是本发明一个实施例的电场装置的立体示意图,该电场装置包括放电极和吸附极。
在本实施例中,电场装置包括多个放电极和吸附极,放电极包括第一放电极619、第二放电极629、第三放电极639、第四放电极649以及其余的八个放电极,吸附极为图9A和图9B所示电场吸附装置1100,电场吸附装置1100中的多个电场单元结构形式相同。其中,吸附极参考图9A和图9B所示的电场吸附装置的相关描述,此处不再详述。如图10所示,每一个电场单元的每一个侧壁上与放电极最短距离617处的部分不设置进气孔或出气孔,例如当电场单元的通道的垂直于轴线的截面为正多边形时,每一个侧壁的中线上不设置进气孔或出气孔(如图9A和9B所示的电场吸附装置)。例如第一电场单元610的每一个侧壁上与放电极619距离最近的部分都不设置进气孔或出气孔,从而使得该部分形成积尘部分。
参照图10,第一放电极619穿设于第一电场单元610的通道内,第一放电极619和第一电场单元610之间形成第一电场,第二电场单元620、第三电场单元630、第四电场单元640与第二放电极629、第三放电极639、第四放电极649分别形成第二电场、第三电场、第四电场,以此类推,其余的电场单元分别与一个放电极分别形成电场。
由于每个电场单元的通道被侧壁环绕成的与轴向方向垂直的截面为正六边形,放电极优选平行于通道的侧壁设置并经过与之对应的电场单元截面内切圆的圆心,此处的放电效率最高。例如,第一放电极619设置于第一电场单元610的通道内,且优选平行于通道的侧壁设置并经过第一电场单元610截面内切圆的圆心,以此类推其他放电极与电场单元的关系。
参照图9B、图10,本实施例中,A为进气方向,B为出气方向,以气体在第一电场、第二电场、第三电场中流动的情况为例进行说明,其他电场的情况以此类推。
对于第一电场,气体通过第一电场单元610中的第一侧壁611、第二侧壁612、第六侧壁616上的进气孔进入第一电场,气体进入方向与第一电场内离子流方向不垂直;由于第一侧壁611、第二侧壁612、第六侧壁616上的进气孔与第三侧壁613、第四侧壁614、第五侧壁615上的出气孔错位排布,气流可以流向多个相邻的电场单元,气流在中空的电场单元610内流动紊乱,经过第一放电极619附近的颗粒物越多,与放电极619碰撞越多,带电粒子越多,提高了吸附效率。另外,由于第一电场具有两个斜面,斜面进风使得气流在中空的第一电场单元610内流动更加紊乱,与侧壁的碰撞增多后,提高了经过第一放电极619附近的频次,从而吸附效率更高。经过第一电场处理后分别由第三侧壁613、第四侧壁614、第五侧壁615上的出气孔排出,并通过第三侧壁613、第五侧壁615上的出气孔进入到第二电场、第三电场。
对于第二电场,一部分气体通过第二电场的吸附单元620中的第四侧壁624、第五侧壁625上的进气孔进入第二电场,另一部分来自第一电场的气体通过第一电场单元610中的第三侧壁613上的孔进入第二电场,这些气体进入方向与第二电场内离子流方向不垂直,由于进气孔与出气孔错位排布,气流在中空的电场单元620内流动紊乱,经过放电极629附近的气流越多,颗粒物与第二放电极629碰撞越多,带电粒子越多,提高了吸附效率。另外,由于第二电场还具有一个斜面,同理,斜面进风使得气流在中空的第二电场单元620内流动更加紊乱,吸附效率更高。经过第二电场处理 后分别由第二电场单元620中的第一侧壁621、第二侧壁622、第三侧壁623上的出气孔排出。
对于第三电场,一部分气体通过第三电场单元630中的第五侧壁635上的进气孔进入第三电场,另一部分通过第一电场单元610中的第五侧壁615上的孔来自第一电场的气体以及通过第三电场单元630中的第四侧壁634上的孔来自第四电场的气体进入第三电场,这些气体进入方向与第三电场内离子流方向不垂直,由于进气孔与出气孔错位排布,气流在中空的第三电场单元630内流动紊乱,经过放电极639附近的气流越多,颗粒物与第三放电极639碰撞越多,带电粒子越多,提高了吸附效率。经过第三电场处理后分别由第三电场单元630中的第一侧壁631、第二侧壁632、第三侧壁633上的出气孔排出。
同理,以此类推出气体进入其他电场发生单元的过程。
本实施例电场装置的电场单元具有在侧壁上开孔的结构,通过侧面进风使得气体在电场内流动紊乱,与第三放电极639碰撞增多,带电粒子增多,提高了整体的吸附效率。

较佳地,所述垫片的剖面呈L形。
