Description
本發明係關於一種靜電集塵裝置及應用該靜電集塵裝置之空氣清靜設備，特別係關於一種可防止電極污損之靜電集塵裝置及應用該靜電集塵裝置之空氣清靜設備。 The present invention relates to an electrostatic precipitator and an air purifying apparatus using the electrostatic precipitator, and more particularly to an electrostatic precipitator capable of preventing electrode fouling and an air purifying apparatus using the electrostatic precipitator.
靜電集塵裝置是藉由電暈放電原理使空氣離子化，待處理氣體中的粒子經由離子撞擊而帶電，並移向集塵板而自待處理氣體中去除，達成淨化氣體的目的。 The electrostatic dust collecting device ionizes the air by the corona discharge principle, and the particles in the gas to be treated are charged by the ion impact, and are moved to the dust collecting plate to be removed from the gas to be treated, thereby achieving the purpose of purifying the gas.
但是，靜電集塵裝置中的放電電極經常會被氣體中的微粒吸附而降低放電效率，而習用的靜電集塵裝置又往往無法避免放電電極污損。 However, the discharge electrode in the electrostatic precipitator is often adsorbed by particles in the gas to reduce the discharge efficiency, and the conventional electrostatic precipitator often cannot avoid the fouling of the discharge electrode.
例如TW 212318號專利中，其揭示一種放電極4，放電極4上設有尖環狀的凸出物411可產生電暈，但該等凸出物411完全暴露於待處理氣體中，因此氣體中的微粒21將無可避免地逐漸附著在凸出物411上而降低其放電效率。 For example, in the TW 212318 patent, it discloses a discharge electrode 4 on which a sharp-edged projection 411 is provided to generate corona, but the projections 411 are completely exposed to the gas to be treated, thus the gas The fine particles 21 inevitably gradually adhere to the projections 411 to lower their discharge efficiency.
TW 261808號專利則揭示一種電極軸10，軸上設有多個針狀電極14、15、16，這些針狀電極14、15、16同樣是暴露於待處理氣體的流動路徑，因此也無法避免這些針狀電極14、15、16受微粒吸附而污損。 The TW 261808 patent discloses an electrode shaft 10 having a plurality of needle electrodes 14, 15, 16 which are also exposed to the flow path of the gas to be treated, and thus cannot be avoided. These needle electrodes 14, 15, 16 are adsorbed by the particles and stained.
TW I283192號專利則揭示一放電板10形成有孔21及凸露於孔21內的電極22，由於待處理氣體是被引導通過該孔21，因此氣體中的微粒同樣也有容易吸附於電極22的問題。 TW I283192 discloses that a discharge plate 10 is formed with a hole 21 and an electrode 22 that is exposed in the hole 21. Since the gas to be treated is guided through the hole 21, the particles in the gas are also easily adsorbed to the electrode 22. problem.
又，TW M445462號專利揭示在集塵板41之間設有條狀電極42，當待處理氣體被導入集塵板41之間的通道時，這些條狀電極42同樣容易被污損。 Further, the TW M445462 patent discloses that strip electrodes 42 are provided between the dust collecting plates 41, and when the gases to be treated are introduced into the passage between the dust collecting plates 41, the strip electrodes 42 are also easily stained.
由這些前案可見，在本技術領域中，長期存在著放電電極容 易被微粒吸附而污損的問題，雖然TW I359048號專利嘗試藉由脈衝噴氣以清洗被污損的放電電極，此等方式雖能治標，但無法根本解決微粒仍會吸附於放電電極的情形，因此放電電極容易污損的問題，始終未被有效克服。 It can be seen from these prior cases that there is a long-term discharge electrode capacity in the technical field. Although it is easy to be adsorbed by particles and stained, although the TW I359048 patent attempts to clean the contaminated discharge electrode by pulse jet, although this method can cure the target, it cannot fundamentally solve the problem that the particles will still adsorb to the discharge electrode. Therefore, the problem that the discharge electrode is easily stained has not been effectively overcome.
有鑑於此，本發明之主要目的之一係為了提供一種可防止電極污損之靜電集塵裝置。 In view of the above, one of the main objects of the present invention is to provide an electrostatic precipitator capable of preventing electrode fouling.
為了達成前述及其他目的，本發明提供一種靜電集塵裝置，其包括至少二平行設置的板狀集塵電極、至少一平行設於相鄰集塵電極之間且呈板狀之高壓導電單元、以及若干絕緣件，相鄰集塵電極之間定義一氣體流道供待處理氣體沿一氣體流動方向流動，該氣體流道具有一進氣端及一出氣端，該高壓導電單元具有一鄰近氣體流道進氣端之端部，該高壓導電單元係供一高壓電源電連接而與集塵電極之間具有電位差，該高壓導電單元之兩面分別設有多個在一垂直方向上延伸之放電電極，該垂直方向與氣體流動方向垂直，該些絕緣件係設於該高壓導電單元而分別位於該氣體流動方向上的不同位置，且該些絕緣件係位於該些放電電極之間，其中在該氣體流動方向上，該些放電電極係被該些絕緣件所遮蔽，而在該垂直方向上，該些放電電極未被該些絕緣件所遮蔽。 In order to achieve the foregoing and other objects, the present invention provides an electrostatic precipitator comprising at least two plate-shaped dust collecting electrodes arranged in parallel, at least one high-voltage conductive unit disposed in parallel between adjacent collecting electrodes, and having a plate shape. And a plurality of insulating members, a gas flow path is defined between the adjacent dust collecting electrodes for flowing the gas to be treated in a gas flow direction, the gas flow prop has an inlet end and an outlet end, and the high-pressure conductive unit has an adjacent gas flow The high-voltage conductive unit is electrically connected to a high-voltage power supply and has a potential difference between the dust-collecting electrode, and the two sides of the high-voltage conductive unit are respectively provided with a plurality of discharge electrodes extending in a vertical direction. The vertical direction is perpendicular to the gas flow direction, and the insulating members are disposed at different positions of the high-voltage conductive unit in the flow direction of the gas, and the insulating members are located between the discharge electrodes, wherein the gas is In the flow direction, the discharge electrodes are shielded by the insulating members, and in the vertical direction, the discharge electrodes are not covered by the insulating members. .
本發明藉由在高壓導電單元上設置多個絕緣件而在氣體流動方向上遮蔽放電電極，放電電極周圍將形成氣流死區，故待處理氣體不會直接與放電電極接觸，而氣體中的微粒帶電後又會朝集塵電極的方向移動，其移動路徑不會經過放電電極，如此就能避免放電電極被污損，從而確保此等靜電集塵裝置維持在較佳的工作效率，進而克服本領域中長期存在卻始終無法有效解決的問題。 The present invention shields the discharge electrode in the flow direction of the gas by providing a plurality of insulating members on the high-voltage conductive unit, and a dead zone of the gas flow is formed around the discharge electrode, so that the gas to be treated does not directly contact the discharge electrode, and the particles in the gas After being charged, it will move toward the dust collecting electrode, and the moving path will not pass through the discharge electrode, so that the discharge electrode can be prevented from being stained, thereby ensuring that the electrostatic dust collecting device is maintained at a better working efficiency, thereby overcoming the present invention. A problem that has existed for a long time in the field but has never been solved effectively.

首先，請參考第1至4圖，在本發明靜電集塵裝置之第一實施例中，靜電集塵裝置係包括多個平行設置且接地的板狀集塵電極10、多個各別平行設於相鄰集塵電極10之間且呈板狀之高壓導電單元20、以及若干絕緣件30。 First, referring to Figures 1 to 4, in the first embodiment of the electrostatic precipitator of the present invention, the electrostatic precipitator comprises a plurality of plate-shaped dust collecting electrodes 10 arranged in parallel and grounded, and a plurality of parallel sets. A high-voltage conductive unit 20 between the adjacent dust collecting electrodes 10 and having a plate shape, and a plurality of insulating members 30.
於相鄰集塵電極10之間定義一氣體流道11供待處理氣體沿一氣體流動方向D1流動，該氣體流道11具有一進氣端12及一出氣端13，其中集塵電極10的數量最少為兩個且可依需求而調整，且多個集塵電極10之間較佳是成等間隔設置，而高壓導電單元20較佳則是設於相鄰集塵電極10的中央，令氣體流道11具有具有固定的寬度。 A gas flow path 11 is defined between the adjacent dust collecting electrodes 10 for the gas to be treated to flow in a gas flow direction D1. The gas flow path 11 has an air inlet end 12 and an air outlet end 13 , wherein the dust collecting electrode 10 The number is at least two and can be adjusted according to requirements, and the plurality of dust collecting electrodes 10 are preferably disposed at equal intervals, and the high-voltage conductive unit 20 is preferably disposed at the center of the adjacent dust collecting electrode 10 to make the gas The flow path 11 has a fixed width.
該高壓導電單元20具有一鄰近氣體流道11進氣端12之端部21，且該高壓導電單元20係供一高壓電源22電連接而與集塵電極10之間具有電位差；該高壓導電單元20之兩面分別設有多個在一垂直方向D2上延伸之放電電極23，該垂直方向D2與氣體流動方向D1垂直，換言之這些放電電極23是分別朝向位於高壓導電單元20兩側的集塵電極10延伸，這些放電電極23在本實施例中係針狀電極，惟放電電極23的外型並不以此 為限；又，如第4圖所示，在高壓導電單元20的寬度方向上可以設置有多排放電電極23，較佳者相鄰排的放電電極23的設置高度呈交錯狀，如此可以使電子雲的分佈更為均勻，有助於提升微粒去除效果。高壓導電單元20的材質可為金屬，例如不銹鋼。 The high-voltage conductive unit 20 has an end portion 21 adjacent to the intake end 12 of the gas flow path 11, and the high-voltage conductive unit 20 is electrically connected to a high-voltage power source 22 to have a potential difference with the dust collecting electrode 10; The two sides of the 20 are respectively provided with a plurality of discharge electrodes 23 extending in a vertical direction D2, the vertical direction D2 being perpendicular to the gas flow direction D1, in other words, the discharge electrodes 23 are respectively directed toward the dust collecting electrodes located on both sides of the high voltage conductive unit 20. 10 extension, these discharge electrodes 23 are needle electrodes in this embodiment, but the appearance of the discharge electrodes 23 is not Further, as shown in FIG. 4, a plurality of discharge electric electrodes 23 may be disposed in the width direction of the high-voltage conductive unit 20, and preferably, the discharge heights of the adjacent discharge electrodes 23 are staggered, so that The distribution of the electron cloud is more uniform, which helps to improve the particle removal effect. The material of the high voltage conductive unit 20 may be a metal such as stainless steel.
各該高壓導電單元20皆設有若干所述絕緣件30，這些絕緣件30係分別位於該氣體流動方向D1上的不同位置，且該些絕緣件30係位於該些放電電極23之間，由於本實施例之氣體流動方向D1為高度方向，因此這些絕緣件30即是位於高壓導電單元20的不同高度。 Each of the high-voltage conductive units 20 is provided with a plurality of the insulating members 30, and the insulating members 30 are respectively located at different positions in the gas flow direction D1, and the insulating members 30 are located between the discharge electrodes 23 due to The gas flow direction D1 of the present embodiment is the height direction, and therefore these insulating members 30 are located at different heights of the high-voltage conductive unit 20.
其中，在該氣體流動方向D1上，該些放電電極23是被該些絕緣件30所遮蔽，這些被絕緣件30遮蔽的放電電極23周圍會形成氣流死區，因為絕緣件30可以阻擋待處理氣體直接流向放電電極23；為了進一步引導氣流遠離放電電極23，設於高壓導電單元20端部21的絕緣件30a具有一錐狀部31a，這些錐狀部31a具有二分別斜向面對兩側集塵電極10的錐面32a，因此錐狀部31a可用以導引待處理氣體朝向集塵電極10的方向流動而避開該些放電電極23，並可避免產生紊流。除此之外，由於進氣端12附近的微粒濃度較高，為了確保鄰近進氣端12的放電電極23不受污損，該絕緣件30a更可具有二自錐狀部31a邊緣延伸之導流翼33a，該二導流翼33a係在氣體流動方向D1上延伸而與鄰近進氣端12的放電電極23相對應，即可進一步避免這些放電電極23與待處理氣體接觸。 In the gas flow direction D1, the discharge electrodes 23 are shielded by the insulating members 30, and the air flow dead zone is formed around the discharge electrodes 23 shielded by the insulating member 30, because the insulating member 30 can block the to-be-processed The gas flows directly to the discharge electrode 23; in order to further guide the gas flow away from the discharge electrode 23, the insulating member 30a provided at the end portion 21 of the high-voltage conductive unit 20 has a tapered portion 31a having two opposite sides facing each other obliquely The tapered surface 32a of the dust collecting electrode 10 can be used to guide the flow of the gas to be treated toward the dust collecting electrode 10 to avoid the discharge electrodes 23, and to avoid turbulence. In addition, since the concentration of the particles near the intake end 12 is relatively high, in order to ensure that the discharge electrode 23 adjacent to the intake end 12 is not stained, the insulating member 30a may have a second extension from the edge of the tapered portion 31a. The flow wing 33a, which extends in the gas flow direction D1 and corresponds to the discharge electrode 23 adjacent to the intake end 12, further prevents the discharge electrodes 23 from coming into contact with the gas to be treated.
又，為了使放電電極23因電暈放電所產生的離子雲可以朝向集塵電極10移動，進而碰撞待處理氣體中的微粒俾使其帶電，因此在所述垂直方向D2上，該些放電電極23並未被絕緣件30所遮蔽，此外在絕緣件30a中，其導流翼33a更具有對應該些放電電極23之眼孔34a，這些眼孔34a的孔徑應稍大於放電電極23的直徑，以利於電暈放電及離子雲移動。 Further, in order to cause the ion cloud generated by the corona discharge of the discharge electrode 23 to move toward the dust collecting electrode 10 and collide with the particles in the gas to be treated to be charged, the discharge electrodes are in the vertical direction D2. 23 is not shielded by the insulating member 30. Further, in the insulating member 30a, the guide vanes 33a further have eye holes 34a corresponding to the discharge electrodes 23, and the apertures of the eye holes 34a should be slightly larger than the diameter of the discharge electrode 23. To facilitate corona discharge and ion cloud movement.
本發明的靜電集塵裝置可以用作除霧器，令待處理氣體中的懸浮液滴帶電而收集於集塵電極10表面；另一方面，此等靜電集塵裝置也可用於一般去除微粒的用途，例如可用以去除油煙或粉塵中的微粒，此時為了讓吸附於集塵電極10表面的微粒不會逐漸累積，本發明的靜電集塵裝置更可進一步包括多個洗滌液導管40(如第2圖所示)，這些洗滌液導管40 係鄰近氣體流道11之出氣端13並分別貼近該些集塵電極10，用以供給洗滌液，令洗滌液沿著集塵電極10表面流下時一併帶走集塵電極10表面的微粒。當然，帶走集塵電極10表面微粒的方式並不以提供洗滌液為限，實際上也可以吹除或震動等其他方式達成，或者該些集塵電極10可為可拆除式設計，當使用一段時間後，使用者可將集塵電極10抽出並加以清潔或替換。 The electrostatic dust collecting device of the present invention can be used as a mist eliminator to collect the suspended liquid droplets in the gas to be treated and collect on the surface of the dust collecting electrode 10; on the other hand, the electrostatic dust collecting device can also be used for generally removing particulates. The utility model can be used, for example, to remove particles in the soot or the dust. In this case, in order to prevent the particles adsorbed on the surface of the dust collecting electrode 10 from accumulating, the electrostatic precipitator of the present invention may further comprise a plurality of washing liquid conduits 40 (eg Figure 2), these washing fluid conduits 40 The gas outlets 13 are adjacent to the gas outlets 13 and are respectively adjacent to the dust collecting electrodes 10 for supplying the washing liquid, so that the washing liquid collects the particles on the surface of the dust collecting electrode 10 when flowing down the surface of the dust collecting electrode 10. Of course, the manner of taking away the surface particles of the dust collecting electrode 10 is not limited to the provision of the washing liquid, and may actually be achieved by other means such as blowing or shaking, or the collecting electrode 10 may be of a detachable design when used. After a period of time, the user can withdraw the dust collecting electrode 10 and clean or replace it.
請接著參考第5、6圖，在本發明的第二實施例中，大部分的元件與第一實施例相似，差異之處包括靜電集塵裝置之圓管狀集塵電極10及圓管狀高壓導電單元20是以同心圓方式排列，亦即集塵電極10與高壓導電單元20之間係同心但不同徑，而位於集塵電極10圓心的高壓導電單元20a則呈桿狀，高壓導電單元20、20a上同樣設有多個絕緣件30b，其中設於圓管狀高壓導電單元20上的絕緣件30b係呈環狀，而設於桿狀高壓導電單元20a的絕緣件30b則呈盤狀，且該些絕緣件30b係位於放電電極23,23a之間，藉此徑向延伸的放電電極23、23a在氣體流動方向D1上可被絕緣件30b遮蔽，而在徑向上則不被遮蔽。當然，圓管狀集塵電極10與圓管狀高壓導電單元20的數量是可進一步增加的，並不以本實施例所示的數量為限，且本實施例的靜電集塵裝置也可以如第一實施例般，進一步設有洗滌液導管40而用以沖洗集塵電極10表面。另需說明的是，本實施例中，放電電極23、23a也可以改為盤狀的放電電極，且其盤狀邊緣也可以呈鋸齒狀，而不以針狀放電電極為限。 Referring to Figures 5 and 6, in the second embodiment of the present invention, most of the components are similar to the first embodiment, and the difference includes the round tubular dust collecting electrode 10 of the electrostatic precipitator and the circular tubular high voltage conductive. The unit 20 is arranged in a concentric manner, that is, the dust collecting electrode 10 and the high-voltage conductive unit 20 are concentric but different in diameter, and the high-voltage conductive unit 20a located at the center of the dust collecting electrode 10 has a rod shape, and the high-voltage conductive unit 20, 20a is also provided with a plurality of insulating members 30b, wherein the insulating member 30b disposed on the circular tubular high-voltage conductive unit 20 is annular, and the insulating member 30b disposed on the rod-shaped high-voltage conductive unit 20a is disk-shaped, and The insulating members 30b are located between the discharge electrodes 23, 23a, whereby the radially extending discharge electrodes 23, 23a are shielded by the insulating member 30b in the gas flow direction D1 and are not shielded in the radial direction. Of course, the number of the circular tubular dust collecting electrode 10 and the circular tubular high-voltage conductive unit 20 can be further increased, and is not limited to the number shown in this embodiment, and the electrostatic dust collecting device of the embodiment can also be the first one. As in the embodiment, a washing liquid conduit 40 is further provided for flushing the surface of the dust collecting electrode 10. It should be noted that, in this embodiment, the discharge electrodes 23, 23a may also be changed to a disk-shaped discharge electrode, and the disk-shaped edge may also be in a zigzag shape instead of the needle-shaped discharge electrode.
前述靜電集塵裝置2除了單獨使用外，也可以與第7圖所示的渦捲式模組3一併使用而成為一空氣清淨設備1，空氣清淨設備1除了工業用途之外，也有可能應用於家用空氣清淨設備。 The electrostatic precipitator 2 can be used together with the scroll module 3 shown in Fig. 7 as an air cleaning device 1 in addition to the above, and the air cleaning device 1 can be applied in addition to industrial use. For household air cleaning equipment.
請進一步搭配第8圖，該渦捲式模組3包括一呈筒狀的殼體50、一繞著殼體50軸心呈渦捲狀排列之浪板60、及一設於浪板60一側並隨著浪板60一併繞著殼體50軸心呈渦捲狀排列之可撓性吸收/吸附元件70。 Further, in conjunction with FIG. 8, the scroll module 3 includes a cylindrical casing 50, a wave plate 60 arranged in a spiral shape around the axis of the casing 50, and a wave plate 60 disposed on one side of the wave plate 60. The flexible absorbing/adsorbing member 70 is spirally arranged around the axis of the housing 50 along with the wave plate 60.
該殼體50具有一上開口51及一下開口52，本實施例為了將浪板60及可撓性吸收/吸附元件70加以固定，於殼體50的下開口52處設有呈板狀的支撐架80，惟所述支撐架80的外型並不以本實施例所示者為限。 The housing 50 has an upper opening 51 and a lower opening 52. In this embodiment, in order to fix the wave plate 60 and the flexible absorbing/adsorbing member 70, a plate-shaped support frame is provided at the lower opening 52 of the housing 50. 80, but the appearance of the support frame 80 is not limited to the one shown in this embodiment.
該浪板60可以由具有可撓性的輕質、耐酸鹼塑膠板(例如聚丙烯)製成，其可預先加工形成波浪狀的紋路，而後再繞著殼體50的軸已呈渦捲狀排列設置。 The wave plate 60 can be made of a flexible, acid-resistant plastic sheet (such as polypropylene) which can be pre-machined to form a wavy pattern and then has a spiral shape around the axis of the housing 50. Arrange the settings.
該可撓性吸收/吸附元件70係設於浪板60一側，並隨著浪板60一併繞著殼體50的軸心呈渦捲狀排列設置，藉此該可撓性吸收/吸附元件70與浪板60之間即可自然形成多個沿著殼體50軸向延伸的通道65，這些通道65的間隙可以藉由選用具有適當波面高度的浪板60而有效地控制，亦即這些通道65的間隙約略就是浪板60波浪紋中，波峰到波谷之間的距離，此等間隙固定的通道65就可以用來精密地控制氣體滯留時間及壓損，以達到良好的氣體污染物去除效果；又，這些通道65係連通於該上開口51及下開口52之間，用以讓待處理的待處理氣體通過，而洗滌液則可自渦捲式模組3由上而下流動以除去待處理氣體中的污染物，且可撓性吸收/吸附元件70本身也可用以吸收、吸附或分解污染物。所述可撓性吸收/吸附元件70可為但不限於聚丙烯(PP)纖維布、聚苯硫醚(PPS，例如由Chevron Phillips Chemical公司所生產的Ryton®)纖維布、或活性碳纖維布，所述纖維布包括但不限於由含有所述材質(即PP、PPS或活性碳等材質)之纖維所製成的織布(weaves)及不織布(nnwovens)；除此之外，所述可撓性吸收/吸附元件70還可以用作一生物濾床，亦即微生物可吸附於可撓性吸收/吸附元件70並用以消化有機污染物，由於此時可撓性吸收/吸附元件70主要用作微生物的載體，因此其材質選擇具有更多彈性，並可視所使用的微生物習性而定；又當可撓性吸收/吸附元件70作為一生物濾床時，空氣清靜設備1較佳者更具有一反洗機構(未繪示)，用以間歇性地反洗該可撓性吸收/吸附元件70，藉此清除積垢且避免微生物過量繁殖而阻塞通道。 The flexible absorbing/adsorbing member 70 is disposed on one side of the wave plate 60, and is arranged in a spiral shape along the axis of the casing 50 together with the wave plate 60, whereby the flexible absorbing/adsorbing member 70 is provided. A plurality of channels 65 extending along the axial direction of the housing 50 can be naturally formed with the wave plate 60. The gaps of the channels 65 can be effectively controlled by selecting the wave plates 60 having appropriate wave heights, that is, the passages 65 The gap is roughly the distance between the peaks and the troughs in the wave pattern of the wave plate 60. These gap-fixed channels 65 can be used to precisely control the gas residence time and pressure loss to achieve good gas contaminant removal effect; The passages 65 are connected between the upper opening 51 and the lower opening 52 for allowing the gas to be treated to pass, and the washing liquid can flow from the scroll module 3 from top to bottom to remove the gas to be treated. The contaminants therein, and the flexible absorbing/adsorbing element 70 itself can also be used to absorb, adsorb or decompose contaminants. The flexible absorbing / adsorbing member 70 can be, but are not limited to polypropylene (PP) fiber cloth, polyphenylene sulfide (the PPS, for example, from Chevron Phillips Chemical Company produced Ryton ®) fiber cloth, or activated carbon fiber cloth, The fiber cloth includes, but is not limited to, weaves and nnwovens made of fibers containing the material (ie, PP, PPS, or activated carbon); in addition, the flexible cloth The absorbing/adsorbing element 70 can also be used as a biofilter bed, i.e., microorganisms can be adsorbed to the flexible absorbing/adsorbing element 70 and used to digest organic contaminants since the flexible absorbing/adsorbing element 70 is primarily used as The carrier of the microorganism, therefore, the material selection has more flexibility, depending on the microbial habit used; and when the flexible absorption/adsorption element 70 is used as a biological filter bed, the air cleaning device 1 preferably has one A backwashing mechanism (not shown) is used to intermittently backwash the flexible absorbing/adsorbing member 70, thereby removing fouling and preventing microbial overgrowth to block the passage.
為了方便將浪板60及可撓性吸收/吸附元件70捲繞固定，本實施例的渦捲式模組3還使用了一心軸90，該心軸90係設於呈渦捲狀排列的浪板60與可撓性吸收/吸附元件70的中心；組裝時，首先如第9圖所示，將浪板60及可撓性吸收/吸附元件70的一端以按壓或其他方式固定於心軸90，接著如第10圖所示，將浪板60及可撓性吸收/吸附元件70一圈圈地繞著心軸90纏繞，待纏繞固定圈數之後，就可以將浪板60與可撓性吸收 /吸附元件70放入殼體50中，而形成如第7圖所示的結構型態。值得注意的是，該等心軸90在本創作中除了可用作浪板60及可撓性吸收/吸附元件70的捲繞軸心之外，另一方面又恰可將浪板60及可撓性吸收/吸附元件70軸心處之空隙加以填塞，確保待處理氣體必可經過間隙固定的通道65俾受到吸收、吸附等處理，而不會經由前述空隙流出。 In order to facilitate winding and fixing the wave plate 60 and the flexible absorbing/adsorbing member 70, the scroll module 3 of the present embodiment further uses a mandrel 90 which is disposed on the wave plate 60 arranged in a spiral shape. And the center of the flexible absorbing/adsorbing member 70; when assembled, first, as shown in Fig. 9, one end of the wave plate 60 and the flexible absorbing/adsorbing member 70 is fixed to the mandrel 90 by pressing or otherwise, and then As shown in Fig. 10, the wave plate 60 and the flexible absorbing/adsorbing member 70 are wound around the mandrel 90 in a circle. After the number of windings is wound, the wave plate 60 and the flexible body can be absorbed. The adsorption member 70 is placed in the casing 50 to form a structural form as shown in Fig. 7. It should be noted that in the present creation, the mandrels 90 can be used as the winding axis of the wave plate 60 and the flexible absorbing/adsorbing member 70, and on the other hand, the wave plate 60 and the flexibility can be justified. The gap at the axial center of the absorbing/adsorbing member 70 is filled to ensure that the gas to be treated must be subjected to absorption, adsorption, etc. through the gap-fixed passage 65 without flowing out through the aforementioned gap.
需說明的是，渦捲式模組3可以導入洗滌液而用來吸收(absorption)氣體污染物，惟在本創作的其他應用場合中，渦捲式模組3也可不導入洗滌液，而可改用活性碳或其他吸附性材質製成的渦捲式模組3來吸附(adsorption)氣體污染物。 It should be noted that the scroll module 3 can be introduced into the washing liquid to absorb the gas contaminants. However, in other applications of the present invention, the scroll module 3 can also not introduce the washing liquid. The scroll module 3 made of activated carbon or other adsorbent material is used to adsorb gaseous pollutants.
又，待處理氣體可先後流經渦捲式模組3的通道65及靜電集塵裝置2的氣體流道11，待處理氣體首先經由渦捲式模組3初步淨化，而後再利用靜電集塵裝置2對待處理氣體進行二次淨化，同時除去待處理氣體中挾帶的洗滌液液珠；當然，待處理氣體流通的順序並不以此為限。 Moreover, the gas to be treated may flow through the channel 65 of the scroll module 3 and the gas channel 11 of the electrostatic precipitator 2, and the gas to be treated is firstly purified through the scroll module 3, and then electrostatic dust collection is utilized. The device 2 performs secondary purification of the treated gas while removing the washing liquid droplets in the gas to be treated; of course, the order in which the gas to be treated is circulated is not limited thereto.
基於上述說明可知，本發明藉由在高壓導電單元上設置多個絕緣件而在氣體流動方向上遮蔽放電電極，放電電極周圍將形成氣流死區，故待處理氣體不會直接與放電電極接觸，而氣體中的微粒帶電後又會朝集塵電極的方向移動，其移動路徑不會經過放電電極，如此就能避免放電電極被污損，從而確保此等靜電集塵裝置維持在較佳的工作效率，進而克服本領域中長期存在卻始終無法有效解決的問題。 Based on the above description, the present invention shields the discharge electrode in the gas flow direction by providing a plurality of insulating members on the high-voltage conductive unit, and a gas flow dead zone is formed around the discharge electrode, so that the gas to be treated does not directly contact the discharge electrode. When the particles in the gas are charged, they will move toward the dust collecting electrode, and the moving path will not pass through the discharge electrode, so that the discharge electrode can be prevented from being stained, thereby ensuring that the electrostatic dust collecting device is maintained in a better work. Efficiency, and thus overcome the problems that have long existed in the field but have not been effectively solved.
最後，必須再次說明的是，本發明於前揭實施例中所揭露的構成元件僅為舉例說明，並非用來限制本案之範圍，其他等效元件的替代或變化，亦應為本案之申請專利範圍所涵蓋。 Finally, it should be noted that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention.
