Structural Composition 本產(chǎn)品由高壓恒流電源和捕焦本體（機械塔體）兩大部分組成，前者選用CS-Ⅲ-PLC型單相LC恒流源靜電沉積用高壓恒流電源；后者結(jié)構(gòu)上可選用FD蜂窩式、SJD濕管式、TD套筒式（同心圓式）或GD管是。四種結(jié)構(gòu)的本體均主要由筒體和放電極（電暈極）以及吸捕極（沉淀極）組成。 This product consists of two parts: high voltage constant current power supply and coke catching body (mechanical tower body). The former chooses CS-Ⅲ-PLC type single phase LC constant current source for electrostatic deposition. Honeycomb type, SJD wet tube type, TD sleeve type (concentric circle type) or GD tube type. The bodies of the four structures are mainly composed of a cylinder, a discharge electrode (corona electrode), and a trapping electrode (precipitation electrode). 套筒式電捕A-A剖面 管式電捕A-A剖面 沉淀極 電暈極 Sleeve Type Electrical Precipitator A-A Profile Tube Electrical Precipitator A-A Profile Precipitation Polar Corona Polar 電源輸入 控制柜 高壓發(fā)生器 沉淀極 電暈極 筒體 蜂窩式電捕A-A剖面 Power Input Control Cabinet High Voltage Generator Precipitation Polar Corona Polar Cylinder Honeycomb Electric Trap A-A Profile 三、工作原理 III. Working Principle 高壓恒流電源產(chǎn)生的負高壓，接入電暈極（陰極），它與沉淀極（陽極）之間產(chǎn)生電場，電場強度超過一定極限后在陰陽兩極間即產(chǎn)生電暈放電。此時流經(jīng)電場區(qū)的氣體發(fā)生電離，產(chǎn)生大量的離子和電子。周圍可聽見強烈的電磁蜂聲，光線暗時可見紫蘭色電暈。通過電場的煤氣中的焦油、粉塵、水霧等粒子與離子或電子結(jié)合而荷電，在電場力的作用下向兩極運動。 The negative high voltage generated by the high-voltage constant-current power supply is connected to the corona polar (cathode), and an electric field is generated between it and the precipitation polar (anode). After the electric field strength exceeds a certain limit, a corona discharge shall be generated between the cathode and the anode poles. In this case, the gas flowing through the electric field area shall be ionized, and a large number of ions and electrons may be generated as well. Strong electromagnetic buzzing sounds can be heard around. Violet corona can be seen when the light is dark. Particles such as tar, dust, and water mist passing through the electric field are combined with ions or electrons to be charged, and move to the poles under the action of the electric field force. 由于電子質(zhì)量小，運動速度快，空間分布廣，所以主要是荷負電的粒子向沉淀極運動。到達沉淀極板中和后，依靠殘存的靜電引力和分子間凝聚力首先吸附于沉淀極，而后靠自身重力沿極板下落，通過焦油出口排出。 Due to the small mass of electrons, fast movement speed and wide spatial distribution, it is mainly that the negatively charged particles move towards the precipitation pole. After reaching the precipitation plate for neutralization, it is first adsorbed on the precipitation electrode by the residual electrostatic attraction and intermolecular cohesion, and then falls along the plate by its own gravity and is discharged through the tar outlet. 四、本體分類 IV.

Introduction of CS-Ⅲ-PLC Single-phase LC Constant Current Source 本產(chǎn)品由恒流源控制柜和高壓發(fā)生器兩部分組成。前者包括L-C恒流源①；繼電和保護電路②；后者包括高壓變電器③和硅整流橋④ This product consists of a constant current source control cabinet and a high voltage generator. The former includes L-C constant current source①; relay and protection circuit ②; the latter includes high voltage transformer ③ and silicon rectifier bridge ④ 電網(wǎng)U L-C恒流源 高壓變壓器 整流橋 本體電場 恒流調(diào)節(jié)和過氧控制電路 過壓和持續(xù)欠電壓保護電路 Grid U L-C Constant Current Source High Voltage Transformer Rectifier Bridge Electric Field of Unit Main Body Constant Current Regulation & Peroxygen Control Circuit Overvoltage & Continuous Undervoltage Protection Circuits 本產(chǎn)品由L-C組成的四端網(wǎng)絡作為恒源流 ，在它的輸出端可以獲得與輸入電壓（網(wǎng)電壓）成正比而與負載阻抗變化無關(guān)的電流。其輸出電流和電網(wǎng)輸入電流可分別用下式表達： This product consists of a four-terminal network composed of L-C as a constant source current. At its output, it can obtain a current that is proportional to the input voltage (grid voltage) and has nothing to do with the change in load impedance. Its output current and grid input current can be expressed by the following formulas: 式中a為復常數(shù)，b、c為實常數(shù)，Ui、Ii、和Uo、Io分別為輸入（電網(wǎng)）電壓、電流和輸出（電場）電壓、電流，RL為電場負載等效阻抗。 Where a is a complex constant, b and c are real constants, Ui, Ii, and Uo, Io are the input (grid) voltage, current, and output (electric field) voltage and current, and RL is the equivalent impedance of the electric field load. 由式（1）可知，輸出電流僅與電網(wǎng)電壓有關(guān)，而電網(wǎng)電壓基本上可以認為是恒定的，從而Io恒定，這就是恒流的含義。 It can be known from formula (1) that the output current is only related to the grid voltage, and the grid voltage can basically be considered constant, so that Io is constant, which is the meaning of constant current. 當電場電暈轉(zhuǎn)化為貫穿性擊穿，即RL→0時，根據(jù)Uo=IoRL，有Uo→0,根據(jù)式（2），則有Ii→0。由于這種變化是同步的，即RL降低時，Uo同時降低，輸入功率UiIi降低，電源提供給放電區(qū)的功率Io2RL隨等效電阻RL同步線性下降，即閃絡能量降低，故而電場擊穿的概率比其它電源低得多。即使產(chǎn)生擊穿，也能迅速恢復，無需長時間封鎖電源。 When the electric field corona is transformed into penetrating breakdown, that is, RL → 0, according to Uo = IoRL, there is Uo → 0, and according to formula (2), there is Ii → 0. Because this change is synchronous, that is, when RL decreases, Uo decreases at the same time, input power UiIi decreases, and the power Io2RL provided by the power supply to the discharge area decreases linearly and synchronously with the equivalent resistance RL, that is, the flashover energy decreases. The probability is much lower than other power sources. Even if a breakdown occurs, it can be quickly recovered without the need to block the power for a long time. 對于可控硅電源輸出電流Io由下式確定 For the thyristor power output current Io is determined by the following formula Io=Ii= 式中Σz為回路總阻抗，即電源的永久性阻抗，其值很小。 Where Σz is the total loop impedance, that is, the permanent impedance of the power supply, and its value is small. 由式（3）可知，一旦電場擊穿或短路，即Uo→0時，Io和Ii都將顯著增加，其值可達額定電流的幾倍甚至幾十倍，即時有反饋電路，擊穿瞬間是不起作用的。此時電源提供的功率比正常工作時急劇增加，閃絡或短路能量很大，極易形成電源本身或電暈線故障。 It can be known from formula (3) that once the electric field is broken down or short-circuited, that is, when Uo → 0, Io and Ii will increase significantly, and their values ​​can reach several times or even dozens of times the rated current. There is a feedback circuit immediately, and the breakdown is instant Is not working. At this time, the power provided by the power supply increases sharply than during normal operation, and the flashover or short-circuit energy is very large, which easily causes the power supply itself or the corona wire to malfunction. 電暈功率 實線：恒源流供電特性 虛線：可控硅供電特性 從以上原理分析及放電特性圖可知： 1、抑制電暈閉塞、陰極線肥大 設(shè)備在粉塵濃度增大時，會阻礙帶電粒子的遷移，從而形成電暈“閉塞”。而恒源流在粉塵濃度增大時，輸出電壓會自動升高，可以有效的克服電暈“閉塞”,同時極板、極絲不易積灰，有效抑制陰極線肥大的發(fā)生。 2、恒源流火花放電功率遠小于正常運行功率，對電除塵器機械缺陷不敏感，故可以將運行功率提至極限狀態(tài)運行。 3、與恒源流負反饋放電特性相反，可控硅電源放電呈正饋特性，極易發(fā)展為火花放電，火花放電功率遠大于正常運行功率，故而發(fā)生火花放電的頻率高，能極大。為確保設(shè)備安全，只能在低電暈功率水平運行。 4、恒源流輸入輸出均為正弦波，輸入阻抗呈阻性。經(jīng)數(shù)學推導可得知U1與I1同相，因而功率因數(shù)較高。我公司企業(yè)標準COSΨ≥0.95接近1。而電壓源的功率因數(shù)行業(yè)標準為COSΨ≥0.8，同樣的設(shè)備如消耗的有功功率相同，則視在功率電壓源要大的多。恒流電源節(jié)電效果明顯。 六、CS-Ⅲ-PLC型單相LC恒流源主要特點 1.單相恒流高壓電源柜采用西門子S7-200Smart系列PLC控制，有本柜和遠程兩種操作方式。電源的運行參數(shù)和指標通過PLC與DCS或上位機通訊，實現(xiàn)遠程監(jiān)控和啟停。 2.、單相恒流高壓電源柜采用西門子mart700IE，TFT觸摸屏作為人機顯示界面，全中文菜單操作，人機界面友好，實現(xiàn)實時、在線的自動顯示測控； 3.采用人工智能控制，投運過程均按專家預設(shè)程序自動完成，無需人工干預，正確靈敏地在線實時監(jiān)測工作狀態(tài)。 4.工作方式為；（1）火花監(jiān)測模式（2）基礎(chǔ)工作模式； 5.通過上位機遠程監(jiān)控恒流源的運行狀態(tài)，可實現(xiàn)恒流源的遠程起動、停止、電壓、電流、溫度數(shù)據(jù)的實時監(jiān)控，并能在設(shè)備出現(xiàn)開路、短路、過流、過壓、過氧、溫度超限等異常狀態(tài)時遠程切斷電控柜電源，使用安全可靠。 6.實現(xiàn)對用戶設(shè)備遠程監(jiān)控，實時了解現(xiàn)場的運行情況以及進行遠程調(diào)試、診斷。 7.單相恒流高壓電源柜源采用以太網(wǎng)通訊接口，可將電源柜與濕式電除塵DCS控制系統(tǒng)互連，通訊快速，實現(xiàn)遠程操作，數(shù)據(jù)共享。 8.完善的保護功能當設(shè)備使用出現(xiàn)異常時，系統(tǒng)自動檢測故障，發(fā)出聲光報警并顯示報警信息。當各絕緣箱的溫度超過上下限定值時，發(fā)出報
