GMC高溫布袋除塵器長期處理高溫含塵煙氣，煙氣中常裹挾大量細微可燃粉塵，靜電導(dǎo)出裝置是防范靜電積聚放電、避免粉塵燃爆隱患的核心穩(wěn)定屏障，該機型長期處于高溫運行環(huán)境，普通靜電導(dǎo)出結(jié)構(gòu)易出現(xiàn)性能衰減、連接失效的問題，若安裝調(diào)試環(huán)節(jié)存在疏漏，靜電持續(xù)積聚形成隱蔽點火源，會直接引發(fā)嚴重的穩(wěn)定事故，結(jié)合高溫布袋除塵器的專屬運行特性，嚴格執(zhí)行靜電導(dǎo)出裝置的安裝調(diào)試穩(wěn)定要求，是確定設(shè)備全生命周期本質(zhì)穩(wěn)定的核心環(huán)節(jié)。

The GMC high-temperature bag filter is used for long-term processing of high-temperature dusty flue gas, which often carries a large amount of fine combustible dust. The electrostatic discharge device is the core stable barrier to prevent static electricity accumulation and discharge, and to avoid dust explosion hazards. This model operates in a high-temperature environment for a long time, and ordinary electrostatic discharge structures are prone to performance degradation and connection failure. If there are omissions in the installation and commissioning process, static electricity will continue to accumulate and form hidden ignition sources, which will directly cause serious stability accidents. Combining the exclusive operating characteristics of high-temperature bag filters, strictly implementing the installation, commissioning and stability requirements of electrostatic discharge devices is the core link to determine the essential stability of the equipment throughout its life cycle.

安裝前部件穩(wěn)定核驗

Stability verification of components before installation

正式開展安裝作業(yè)前，需要對所有靜電導(dǎo)出相關(guān)部件開展全維度穩(wěn)定核驗，杜不能合格部件進入安裝環(huán)節(jié)。逐一檢查所有金屬連接部件，包括接地導(dǎo)線、連接端子、導(dǎo)電連接件的材質(zhì)屬性，確認部件的高溫、不易腐蝕性能適配除塵器的高溫運行環(huán)境，不會在長期高溫?zé)煔鉀_刷下快氧化銹蝕，導(dǎo)致導(dǎo)電性能快衰減失效。檢查所有部件的表面狀態(tài)，無明顯的氧化層、絕緣涂層覆蓋，部件本體無裂紋、變形、截面缺損等缺陷，導(dǎo)電通路上不存在先天的高阻抗薄弱點。

Before officially starting the installation operation, it is necessary to conduct a comprehensive stability verification of all static electricity export related components to prevent unqualified components from entering the installation process. Inspect all metal connection components one by one, including the material properties of grounding wires, connection terminals, and conductive connectors, to confirm that the high-temperature and non corrosive properties of the components are suitable for the high-temperature operating environment of the dust collector, and will not rapidly oxidize and rust under long-term high-temperature flue gas erosion, resulting in rapid deterioration and failure of conductivity. Check the surface condition of all components, there is no obvious oxide layer or insulation coating coverage, the component body has no defects such as cracks, deformation, or cross-sectional defects, and there are no inherent high impedance weak points on the conductive path.

核驗濾袋的不怕靜電性能，確認高溫濾料內(nèi)部的導(dǎo)電纖維分布均勻，無局部導(dǎo)電纖維斷裂缺失的區(qū)域，濾袋任意位置的導(dǎo)電性能都處于穩(wěn)定區(qū)間，不會出現(xiàn)局部靜電隔離的“孤島”現(xiàn)象。核驗濾袋配套的金屬袋籠，確認袋籠整體導(dǎo)電連續(xù)性完好，所有焊接節(jié)點無虛焊、脫焊情況，袋籠表面無絕緣噴涂層，不會阻斷濾袋與花板之間的靜電導(dǎo)出路徑。核驗整機的接地主干網(wǎng)，確認主干網(wǎng)的接地性能穩(wěn)定，無局部斷點、嚴重銹蝕的情況，主干網(wǎng)全部避開強電磁干擾區(qū)域，不會出現(xiàn)靜電導(dǎo)出受阻的問題。所有部件核驗合格后分類存放，避免部件表面沾染絕緣油污、涂層，破壞原有導(dǎo)電性能。

Verify the anti-static performance of the filter bag, confirm that the conductive fibers inside the high-temperature filter material are evenly distributed, and there are no areas where local conductive fibers are broken or missing. The conductivity of the filter bag at any position is in a stable range, and there will be no "island" phenomenon of local electrostatic isolation. Verify the metal bag cage matched with the filter bag, confirm that the overall conductivity continuity of the bag cage is intact, all welding nodes are free of virtual welding or detachment, and there is no insulation spray coating on the surface of the bag cage, which will not block the static electricity export path between the filter bag and the flower board. Verify the grounding backbone network of the entire machine, confirm that the grounding performance of the backbone network is stable, without local breakpoints or severe corrosion, and that the backbone network avoids areas with strong electromagnetic interference, and there is no problem of static electricity export obstruction. All components shall be classified and stored after passing the verification to avoid contamination of insulation oil stains and coatings on the surface of the components, which may damage the original conductivity.

安裝過程穩(wěn)定管控

Stable control during installation process

安裝作業(yè)全程嚴格遵循防止靜電穩(wěn)定規(guī)范，所有作業(yè)人員佩戴防止靜電手環(huán)，避免人體攜帶的靜電意外放電，同時作業(yè)區(qū)域內(nèi)嚴禁動用明火，嚴禁進行任意可能產(chǎn)生火花的敲擊作業(yè)，防止安裝過程中殘留的細微粉塵被意外點燃。從基礎(chǔ)的部件開始逐層安裝，起先將袋籠平穩(wěn)裝入濾袋內(nèi)部，確認袋籠與濾袋內(nèi)壁全部貼合，無局部懸空錯位的情況，確定濾袋表面產(chǎn)生的靜電可以順暢傳遞到袋籠上。

The entire installation process strictly follows the regulations for preventing static electricity stability. All operators wear anti-static wristbands to avoid accidental discharge of static electricity carried by the human body. At the same time, open flames are strictly prohibited in the work area, and any striking operations that may generate sparks are strictly prohibited to prevent the accidental ignition of residual fine dust during the installation process. Starting from the basic components, install them layer by layer. At first, smoothly insert the bag cage into the inside of the filter bag, confirm that the bag cage is fully attached to the inner wall of the filter bag, and there is no local suspension or misalignment. Confirm that the static electricity generated on the surface of the filter bag can be smoothly transmitted to the bag cage.

將裝好濾袋的袋籠準(zhǔn)確固定在花板上，確認袋籠的頂部接觸端面與花板金屬表面緊密貼合，接觸位置無絕緣墊片、粉塵雜物遮擋，用細砂紙輕輕打磨接觸點位的局部氧化層，確定兩者之間的導(dǎo)電連續(xù)性全部導(dǎo)通，不會出現(xiàn)接觸不良的高阻抗斷點。依次安裝除塵器的所有金屬殼體段，每拼接一段殼體，就同步在拼接法蘭位置加裝跨接導(dǎo)電連接件，打磨掉法蘭面的防銹漆層，確定各段殼體之間的靜電導(dǎo)出鏈路全部連通，不會出現(xiàn)法蘭之間因密封墊片絕緣形成靜電隔離段。

Accurately fix the bag cage with the filter bag on the flower board, confirm that the top contact end face of the bag cage is tightly attached to the metal surface of the flower board, and that there are no insulation gaskets or dust debris blocking the contact position. Gently polish the local oxide layer at the contact point with fine sandpaper to ensure that the conductivity continuity between the two is fully conductive and there will be no high impedance breakpoints with poor contact. Install all metal shell segments of the dust collector in sequence. For each segment of the shell, install a jumper conductive connector at the joint flange position, polish off the anti rust paint layer on the flange surface, and ensure that all static electricity export links between the segments of the shell are connected. There will be no static electricity isolation segments between the flanges due to sealing gasket insulation.

從除塵器殼體的各個關(guān)鍵點位引出靜電接地支線，包括灰斗、中箱體、凈氣室、進出入口風(fēng)管等所有立金屬部件，各根支線都采用柔性經(jīng)得起高溫導(dǎo)電材質(zhì)，走線避開高溫?zé)煔庵苯記_刷的區(qū)域，避免支線長期受高溫烘烤出現(xiàn)絕緣層破損、芯線氧化的問題。所有支線后期匯聚連接到車間主接地干線上，連接端子采用防松鎖止結(jié)構(gòu)，端子表面涂抹導(dǎo)電防化學(xué)反應(yīng)油脂，防止長期高溫環(huán)境下端子氧化松動，出現(xiàn)導(dǎo)電鏈路斷開的隱患。安裝全程做好各個連接點位的標(biāo)記，記錄所有關(guān)鍵連接節(jié)點的位置，為后續(xù)調(diào)試核驗做好溯源準(zhǔn)備。

Static grounding branch lines are led out from various key points of the dust collector housing, including the ash hopper, middle box body, clean air chamber, inlet and outlet air ducts, and all vertical metal components. Each branch line is made of flexible conductive materials that can withstand high temperatures, and the routing avoids areas directly washed away by high temperature flue gas, avoiding insulation layer damage and core wire oxidation caused by long-term high temperature baking of the branch line. All branch lines will converge and connect to the main grounding line in the workshop in the later stage. The connection terminals adopt anti loosening locking structure, and the surface of the terminals is coated with conductive anti chemical reaction grease to prevent oxidation and loosening of the terminals under long-term high temperature environment, which may lead to the risk of disconnection of the conductive link. Mark all connection points throughout the installation process, record the positions of all key connection nodes, and prepare for traceability for subsequent debugging and verification.
