Description
本創作係為一種靜電除塵裝置，以及一套結合此靜電除塵裝置與過濾網的過濾系統。特別是一種造價較低且堅固耐用的靜電除塵裝置，並使用此一靜電除塵裝置結合各種材質的過濾網，來提升過濾的效率以及過濾網的使用壽命。The creation is an electrostatic precipitator and a filtration system incorporating the electrostatic precipitator and filter. In particular, it is a low-cost and durable electrostatic precipitator, and uses this electrostatic precipitator to combine filters of various materials to improve the efficiency of filtration and the service life of the filter.
近年來，細微粒(PM 2.5)的汙染已引起多數人的注意，許多國家也有PM 2.5濃度超標的問題，嚴重地影響了當地居民的健康。為了有效減少PM 2.5的排放，在各種會排放PM 2.5的汙染源，諸如燃煤發電廠、餐廳與石化產業都設有過濾系統。傳統的過濾系統依其作用方式分成二種，一種是單純使用靜電除塵裝置，其中許多餐廳由於資本額較低，無法安裝昂貴且容易損壞的舊式靜電除塵設備。 In recent years, the pollution of fine particles (PM 2.5 ) has attracted the attention of most people. In many countries, the problem of excessive PM 2.5 concentration has seriously affected the health of local residents. In order to effectively reduce PM 2.5 emissions, filtration systems are available in various sources that emit PM 2.5 , such as coal-fired power plants, restaurants, and the petrochemical industry. Traditional filtration systems are divided into two types according to their mode of action. One is to simply use electrostatic precipitators, many of which cannot install expensive electrostatic precipitators that are expensive and easily damaged due to their low capital.
靜電集塵裝置的作用原理是利用高壓電在其電極上產生電暈放電以釋放大量的離子，使通過的氣流中微粒帶電並經由電場的作用而往靜電集塵裝置的收集板的方向移動，進而被收集板所收集。傳統的靜電集塵裝置，例如二階式靜電集塵器(2-stage Electrostatic Precipitator)，其對於微粒的收集效率雖然相當高，但是電極上的電極線與收集板易因積卡微粒而汙損。其次，傳統的靜電集塵裝置的電極線的結構較為脆弱，容易在集塵過程中因吸取到異物而破損，而且傳統的電極線的價格也比較昂貴。最後，由於傳統的靜電除塵裝置的收集板的設立方向與氣流的流向平行，因此可能會產生背電暈現象，使得被收集板所收集的微粒可能會再次懸浮於氣流中，因而降低了微粒的收集效率。可見傳統的靜電集塵裝置尚有改善的空間。The working principle of the electrostatic precipitator is to generate a corona discharge on the electrode by using high voltage electricity to release a large amount of ions, so that the particles in the passing air stream are charged and moved to the collecting plate of the electrostatic precipitator via the action of the electric field. And then collected by the collection board. A conventional electrostatic precipitator, such as a 2-stage Electrostatic Precipitator, has a relatively high collection efficiency for particles, but the electrode lines and the collecting plates on the electrodes are easily stained by the accumulated particles. Secondly, the structure of the electrode line of the conventional electrostatic precipitator is relatively fragile, and it is easy to be damaged due to the absorption of foreign matter in the dust collecting process, and the price of the conventional electrode wire is relatively expensive. Finally, since the collecting direction of the conventional electrostatic precipitator is parallel to the flow direction of the airflow, a back corona phenomenon may occur, so that the particles collected by the collecting plate may be resuspended in the airflow, thereby reducing the particulate matter. Collect efficiency. It can be seen that there is still room for improvement in the conventional electrostatic precipitator.
另外一種過濾系統是單純使用過濾網進行過濾，然而傳統的過濾網不帶靜電，或者雖帶有靜電卻會隨著使用時間而降低其表面之靜電附著量，因此對於粉塵的去除效率較低，而且粉塵的去除效率也會隨著使用時間的增加而下降。Another type of filtration system uses a filter to filter. However, the conventional filter does not have static electricity, or it has static electricity, which reduces the amount of static adhesion on the surface with time. Therefore, the dust removal efficiency is low. Moreover, the dust removal efficiency also decreases as the use time increases.
有鑑於此，本創作之其中一個目的乃在於提供一種靜電除塵裝置，其結構上較為堅固且成本較低，但同樣能有效達成除塵效果。In view of this, one of the purposes of the present invention is to provide an electrostatic precipitator that is structurally strong and low in cost, but is also effective in achieving dust removal.

Wherein, the inside of the outer casing is hollow and has a chamber. The outer casing also has an air inlet and an air outlet, and the air inlet and the air outlet communicate with the outside of the chamber and the outer casing. The high-voltage electrode assembly is detachably disposed in the outer casing and has a frame body and a plurality of electrode rods arranged in the frame body and connected to the frame body, and each of the electrode rods is provided with a plurality of steel nails and each steel nail The tips point away from the air inlet, and the electrodes are electrically connected to a high voltage power source for discharging at the tip of the steel nail. The grounding metal mesh is detachably disposed in the outer casing and located between the high voltage electrode group and the exhaust port. The grounding metal mesh is provided with a plurality of through holes for the airflow to pass, so that the charged particles can be attracted by the grounded metal mesh. Collect, and then achieve the effect of dust collection.
另外，為了提高粉塵、油滴的過濾效率，本創作還提出了一種過濾系統，其包含有一靜電除塵裝置、一氣體通道與至少一個過濾網。其中，氣體通道是連接靜電除塵裝置的排氣口。過濾網是設於氣體通道內以過濾從排氣口排出的氣流。過濾網是採用靜電濾材製成，靜電濾材可被氣流中的微粒摩擦而帶電，使過濾網表面能穩定帶有靜電以提高過濾網對於粉塵、油滴的過濾效率。In addition, in order to improve the filtration efficiency of dust and oil droplets, the present invention also proposes a filtration system comprising an electrostatic precipitator, a gas passage and at least one filter. Wherein, the gas passage is an exhaust port connected to the electrostatic precipitator. The filter is disposed in the gas passage to filter the airflow discharged from the exhaust port. The filter mesh is made of electrostatic filter material. The electrostatic filter material can be charged by the particles in the airflow, so that the surface of the filter mesh can be stabilized with static electricity to improve the filtration efficiency of the filter mesh for dust and oil droplets.
通過上述靜電集塵裝置的高壓電極組的鋼釘來進行放電，相較於使用電極絲，使用鋼釘的高壓電極組的整體成本較低，且結構上也較為堅固耐用，而且同樣也能達成和電極絲相接近的放電效果。The discharge is performed by the steel nail of the high-voltage electrode group of the electrostatic precipitator, and the high-pressure electrode assembly using the steel nail is lower in overall cost and structurally stronger and more durable than the use of the electrode wire, and can also be achieved. The discharge effect is close to the wire.
在其中一個方面，鋼釘可為其他類合金製成的釘狀結構。In one aspect, the steel nail can be a nail-like structure made of other alloys.
在另一個方面，過濾裝置可用來過濾油煙、粉塵或其他氣流中的微粒。In another aspect, the filtration device can be used to filter particulates in soot, dust or other gas streams.
在另一個方面，高壓電極組的電極棒可採用碳纖維束、不鏽鋼、銅或鋁等導電材料製成。In another aspect, the electrode rod of the high voltage electrode group can be made of a conductive material such as carbon fiber bundle, stainless steel, copper or aluminum.
在另一個方面，外殼可採用絕緣材料(例如聚氯乙烯；PVC)製成。PVC具有質輕、耐化學藥品性優良、流體阻力小、機械強度大與電絕緣性佳的優點，能減少壓損並避免觸電或漏電之危險。In another aspect, the outer casing can be made of an insulating material such as polyvinyl chloride; PVC. PVC has the advantages of light weight, excellent chemical resistance, low fluid resistance, high mechanical strength and good electrical insulation, which can reduce pressure loss and avoid the risk of electric shock or electric leakage.
為了詳細說明本創作之技術特點所在，茲舉以下之二個實施例並配合圖式說明如後，其中：In order to explain in detail the technical features of the present invention, the following two embodiments are described with reference to the following:
如圖1與圖2所示，本創作之第一實施例描述了一種油煙過濾系統1，其包含有一靜電除塵裝置10、一高壓電源20、一後處理濾袋4與一抽風機5，其中靜電除塵裝置10與後處理濾袋4用來過濾氣流中的微粒，抽風機5用來抽氣以形成氣流，使氣流通過靜電除塵裝置10與後處理濾袋4，靜電除塵裝置10的前端設有管路2，靜電除塵裝置10與後處理濾袋4設有管路3，後處理濾袋4與抽風機5之間設有管路6。如圖2所示，後處理濾袋4是設置於靜電除塵裝置10的後側，後處理濾袋4包含有一氣體通道7，氣體通道7連接靜電除塵裝置10並且氣體通道7的內部設有一層中效過濾網8與一層高效過濾網9。高效過濾網9相較於中效過濾網8而具有較高的收集效率。中效過濾網8與高效過濾網9都是採用靜電濾材製成，靜電濾材的材質有多種，其可採用合成纖維(例如聚丙烯)，此方面的資料可參考Vaughn, E Howard-Reed, C 所寫的Fiber Glass vs. Synthetic air filtration media 於International Nonwoven Journal 的文章。其中當氣流通過靜電濾材時，氣流中的微粒將摩擦靜電濾材而使靜電濾材帶電，藉以增加微粒的收集效率。電源20於本實施例中為一高壓電供應器，其型號為Spellman TF_SL30N150，用來提供最高為-30kV(千伏特)的負高壓電的電訊號。As shown in FIG. 1 and FIG. 2, the first embodiment of the present invention describes a soot filter system 1 including an electrostatic precipitator 10, a high voltage power supply 20, a post-treatment filter bag 4 and a blower 5, wherein The electrostatic precipitator 10 and the post-treatment filter bag 4 are used to filter particles in the airflow, and the exhaust fan 5 is used to pump air to form an airflow, and the airflow passes through the electrostatic precipitator 10 and the post-treatment filter bag 4.

The article by Fiber Glass vs. Synthetic air filtration media in the International Nonwoven Journal. When the airflow passes through the electrostatic filter, the particles in the airflow will rub the electrostatic filter to charge the electrostatic filter, thereby increasing the collection efficiency of the particles.

請參考圖1與圖3，其係靜電除塵裝置10的立體圖。靜電除塵裝置10在結構上包含有一外殼30、一高壓電極組40與一接地金屬網50，其中：Please refer to FIG. 1 and FIG. 3 , which are perspective views of the electrostatic precipitator 10. The electrostatic precipitator 10 includes a housing 30, a high voltage electrode assembly 40 and a grounding metal mesh 50, wherein:
外殼30包含有一進氣口31與一排氣口32，並且外殼30的內部是呈中空狀而具有一腔室33，進氣口31與腔室33相連通並且連接管路2，排氣口32連通腔室33以及管路3，外殼30採用PVC之材料製成，藉以達成絕緣的效果。The outer casing 30 includes an air inlet 31 and an air outlet 32, and the interior of the outer casing 30 is hollow and has a chamber 33. The air inlet 31 communicates with the chamber 33 and connects the pipeline 2 to the exhaust port. 32 is connected to the chamber 33 and the pipe 3, and the outer casing 30 is made of a material of PVC to achieve an insulating effect.
請參考圖4至圖6。高壓電極組40是可拆卸地設置於外殼30內，其結構上具有一框體41、九個電極棒42、八十一個螺帽43與八十一個鋼釘44，九個電極棒42係彼此平行地排列於框體41內，並且每個電極棒42的上下二端都連接框體41(如圖4所示)。每個電極棒42都設有外螺紋421，每個鋼釘44都固接螺帽43的外表面，螺帽43為金屬製成，鋼釘44通過螺帽43而螺合於各個電極棒42。於本實施例中，每個電極棒42設有九個鋼釘44(如圖5所示)，各個鋼釘44的尖端441指向遠離進氣口31的方向(亦即指向後續將說明的接地金屬網50的方向)。任二相鄰的鋼釘44之間隔為6公分(cm)，鋼釘44的尖端441的尺寸約為373微米(μm)。各個電極棒42都電連接電源20，使鋼釘44的尖端441能產生電暈放電作用(Corona discharge)，讓通過高壓電極組40的氣流中的微粒能帶電。Please refer to Figure 4 to Figure 6. The high voltage electrode assembly 40 is detachably disposed in the outer casing 30, and has a frame 41, nine electrode rods 42, eighty-one nuts 43 and eighty-one steel nails 44, and nine electrode rods 42. The frames 41 are arranged in parallel with each other, and the upper and lower ends of each of the electrode rods 42 are connected to the frame 41 (as shown in FIG. 4). Each of the electrode rods 42 is provided with external threads 421, each of which is fixed to the outer surface of the nut 43, the nut 43 is made of metal, and the steel nails 44 are screwed to the respective electrode rods 42 by the nuts 43. . In the present embodiment, each of the electrode rods 42 is provided with nine steel nails 44 (as shown in FIG. 5), and the tips 441 of the respective steel nails 44 are directed away from the air inlet 31 (ie, pointing to the ground to be described later). The direction of the metal mesh 50). The spacing between any two adjacent steel nails 44 is 6 cm (cm), and the tip end 441 of the steel nail 44 has a size of about 373 micrometers (μm). Each of the electrode rods 42 is electrically connected to the power source 20 so that the tip end 441 of the steel nail 44 can generate a corona discharge to charge the particles in the gas stream passing through the high voltage electrode group 40.
請參考圖3與圖7。接地金屬網50是可拆卸地設置於外殼30內並位於高壓電極組40與排氣口32之間，接地金屬網50與鋼釘44的尖端441之間的距離為3公分(cm)。接地金屬網50是呈接地的狀態。接地金屬網50具有一外框51並且內部設有大量個通孔52，通孔52用以供氣流通過，接地金屬網50通過外框51而可拆卸地裝設於腔室33。Please refer to FIG. 3 and FIG. 7. The grounding metal mesh 50 is detachably disposed in the outer casing 30 between the high voltage electrode group 40 and the exhaust port 32, and the distance between the ground metal mesh 50 and the tip end 441 of the steel nail 44 is 3 cm. The grounded metal mesh 50 is in a grounded state. The grounding metal mesh 50 has an outer frame 51 and is internally provided with a plurality of through holes 52 for allowing airflow therethrough. The grounding metal mesh 50 is detachably mounted to the chamber 33 through the outer frame 51.
須說明的是，於本實施例的圖3所示，接地金屬網50所形成的平面以及高壓電極組40所形成的平面是大致和氣流的流向(即氣流進入進氣口31的方向)相垂直的，如此可降低背電暈現象發生的機率，讓微粒即使被收集後而再度懸浮於氣流中，再懸浮的微粒也能再次地被接地金屬網50收集。It should be noted that, as shown in FIG. 3 of the present embodiment, the plane formed by the grounding metal mesh 50 and the plane formed by the high voltage electrode group 40 are substantially the same as the flow direction of the airflow (ie, the direction in which the airflow enters the air inlet 31). Vertical, this reduces the chance of back corona occurrence, allowing the particles to be resuspended in the gas stream even after being collected, and the resuspended particles can be collected again by the grounded metal mesh 50.
請回到圖1與圖3。通過本實施例的靜電除塵裝置10的設計，當抽風機5作動而抽風時，氣流將從管路2與進氣口31而進入靜電除塵裝置10的腔室33。當氣流通過高壓電極組40時，在高壓電極組40的鋼釘44尖端441的電暈放電作用下，氣流中的微粒將帶電。之後氣流在流經接地金屬網50時，氣流中帶電的微粒將受到接地金屬網50的吸引而被接地金屬網50所收集，藉以去除氣流中的微粒的數量，降低後處理濾袋4的負荷。Please return to Figure 1 and Figure 3. With the design of the electrostatic precipitator 10 of the present embodiment, when the exhaust fan 5 is actuated to draw air, the airflow enters the chamber 33 of the electrostatic precipitator 10 from the line 2 and the intake port 31. When the gas stream passes through the high pressure electrode group 40, the particles in the gas stream will be charged under the corona discharge of the tip 441 of the steel nail 44 of the high voltage electrode group 40. Then, when the airflow flows through the grounding metal mesh 50, the charged particles in the airflow will be attracted by the grounding metal mesh 50 and collected by the grounding metal mesh 50, thereby removing the amount of particles in the airflow and reducing the load of the post-processing filter bag 4. .
相較於傳統的靜電除塵裝置使用電極絲來使氣流中的微粒帶電，本實施例的靜電除塵裝置10通過使用鋼釘44來使微粒帶電，經發明人多次的試驗結果，本實施例的高壓電極組40能夠產生更高的電場強度與電流密度，使靜電除塵裝置10能具有更高的收集效率。另外，靜電除塵裝置10的整體結構的成本較低，高壓電極組40不易受到氣流中的異物撞擊而毀損，因此增加了靜電除塵裝置的使用壽命，以上皆為本創作之特點所在。Compared with the conventional electrostatic precipitator, the electrode wire is used to charge the particles in the airflow. The electrostatic precipitator 10 of the present embodiment charges the particles by using the steel nail 44. The inventors have repeatedly tested the results of the present embodiment. The high voltage electrode group 40 is capable of generating higher electric field strength and current density, enabling the electrostatic precipitator 10 to have higher collection efficiency. In addition, the overall structure of the electrostatic precipitator 10 is low in cost, and the high-voltage electrode group 40 is not easily damaged by foreign matter in the airflow, thereby increasing the service life of the electrostatic precipitator, and the above are the characteristics of the creation.
本創作另提供一第二實施例，請參考圖8。第二實施例的油煙過濾系統1包含有一靜電除塵裝置10與連接靜電除塵裝置10的一氣體通道7，其中氣體通道7內部同樣具有相同結構與相同材質的中效過濾網8與高效過濾網9。Another second embodiment of the present invention is provided. Please refer to FIG. 8. The soot filter system 1 of the second embodiment comprises an electrostatic precipitator 10 and a gas passage 7 connected to the electrostatic precipitator 10, wherein the inner passage of the gas passage 7 has the same structure and the same material and the high efficiency filter 9 .
靜電除塵裝置10包含有二套高壓電極組40a,40b與接地金屬網50a,50b，其中高壓電極組40a具有12個電極棒42與144個鋼釘44，鋼釘44彼此間隔為4.7公分。高壓電極組40b則設有196個鋼釘44彼此間隔為4公分，鋼釘44。上述電極棒42係使用鑽頭而設有多個固定孔422，使各個鋼釘44都分別以緊配的方式而一對一地固定於各個固定孔422。The electrostatic precipitator 10 includes two sets of high voltage electrode sets 40a, 40b and grounded metal meshes 50a, 50b, wherein the high voltage electrode set 40a has twelve electrode bars 42 and 144 steel nails 44, and the steel nails 44 are spaced apart from each other by 4.7 cm. The high voltage electrode group 40b is provided with 196 steel nails 44 spaced apart from each other by 4 cm and steel nails 44. The electrode rod 42 is provided with a plurality of fixing holes 422 by using a drill, and each of the steel nails 44 is fixed to each of the fixing holes 422 one by one in a tight fit.
請參考圖9，其係第二實施例的油煙過濾系統1的微粒累積量與收集效率的關係圖。其中，F M+F H+ESP表示了第二實施例的實測數據(即包含有一層高效過濾網9與一層中效過濾網8，並使用高壓電極組40a,40b與接地金屬網50a,50b)。F H+F H表示了單純使用二層高效過濾網9(但不使用高壓電極組40a,40b與接地金屬網50a,50b)來進行過濾的情況，F M+F H表示了單純使用一層高效過濾網9與一層中效過濾網8來進行過濾的情況(但不使用高壓電極組40a,40b與接地金屬網50a,50b)。可以看到，在三種情況下，初始的收集效率都高於95%，但隨著微粒的累積，將使過濾系統1的收集效率降低，當微粒累積量達到8g/m 2時，只有第二實施例的過濾系統1的收集效率還能維持在90%，能符合了「餐飲業油煙空氣汙染物管制規範及排放標準(草案)」的規範。 Please refer to FIG. 9, which is a graph showing the relationship between the cumulative amount of particles and the collection efficiency of the soot filter system 1 of the second embodiment. Wherein, F M +F H +ESP represents the measured data of the second embodiment (ie, comprises a layer of high efficiency filter 9 and a layer of medium efficiency filter 8 and uses high voltage electrode sets 40a, 40b and grounded metal mesh 50a, 50b ). F H + F H represents the case where the two-layer high-efficiency filter 9 (but without the high-voltage electrode groups 40a, 40b and the grounded metal mesh 50a, 50b) is used for filtering, and F M + F H represents the use of a single layer of high efficiency. The filter 9 and the intermediate effect filter 8 are used for filtration (but the high voltage electrode sets 40a, 40b and the grounded metal mesh 50a, 50b are not used). It can be seen that in the three cases, the initial collection efficiency is higher than 95%, but with the accumulation of particles, the collection efficiency of the filtration system 1 will be lowered, and when the cumulative amount of particles reaches 8 g/m 2 , only the second The collection efficiency of the filtration system 1 of the embodiment can be maintained at 90%, which can meet the specifications of the "Food and Beverage Air Pollution Control Regulations and Emission Standards (Draft)".
