煙氣脫硫塔泄漏部位:脫硫塔下塔壁、噴淋管、除霧器、脫硫塔上塔壁、脫硫塔與母液管的焊接位置、吸收塔入口煙道與吸收塔壁的連接處、循環(huán)罐壁的板漏或底板漏。
Leakage position of flue gas desulfurization tower: lower tower wall of desulfurization tower, spray pipe, demister, upper tower wall of desulfurization tower, welding position between desulfurization tower and mother liquid pipe, connection between inlet flue of absorption tower and absorption tower wall, plate leakage or bottom plate leakage of circulating tank wall.
煙氣脫硫塔設(shè)備泄漏如何處理?
How to deal with the leakage of FGD tower equipment?
1.準(zhǔn)備好脫硫塔管道和脫硫塔設(shè)備的封堵工具和材料,以及待更換脫硫塔設(shè)備的備件。
1. Prepare plugging tools and materials for desulfurization tower pipelines and desulfurization tower equipment, as well as spare parts for desulfurization tower equipment to be replaced.
2.檢查設(shè)備泄漏表面,清理影響施工作業(yè)的物體;除去磨損零件表面的油(如果現(xiàn)場不允許動火作業(yè),可以使用化學(xué)清洗)。
2. Check the leakage surface of the equipment and clean up the objects affecting the construction operation; Remove the oil on the surface of worn parts (chemical cleaning can be used if hot work is not allowed on site).
3.將修補材料嚴(yán)格按比例混合,攪拌均勻。并涂抹在脫硫塔的泄漏部位及其周圍,并反復(fù)涂抹,以確保其密實度。
3. Mix the repair materials in strict proportion and mix evenly. And apply it to the leakage part of the desulfurization tower and its surroundings, and apply it repeatedly to ensure its compactness.
4.保證涂層的固化時間(常溫下6小時,碘鎢燈加熱到60左右才2小時)。
4. Ensure the curing time of the coating (6 hours at room temperature and 2 hours when the iodine tungsten lamp is heated to about 60).
5.用研磨機將表面粗糙化,以去除泄漏表面的異物和氧化層,露出金屬的自然顏色;用干凈的棉紗和無水乙醇清洗。
5. Roughen the surface with a grinder to remove foreign matters and oxide layer on the leaking surface and expose the natural color of the metal; Clean with clean cotton yarn and absolute ethanol.
6.檢查修補表面和材料的應(yīng)用強度。
6. Check the application strength of the repaired surface and materials.
廢氣泄漏不僅可能造成空氣污染,還可能造成人員中毒。根據(jù)環(huán)保政策要求,廢氣處理設(shè)備在生產(chǎn)過程中需要連續(xù)在線運行,否則生產(chǎn)過程中造成的空氣污染將面臨巨額罰款。脫硫塔管道或脫硫塔設(shè)備發(fā)生泄漏時,需要立即停產(chǎn)修理。但是,如果脫硫塔堵漏工藝過于復(fù)雜或修理時間過長,將嚴(yán)重影響生產(chǎn),給企業(yè)效益帶來巨大損失。
Exhaust gas leakage may not only cause air pollution, but also cause personnel poisoning. According to the requirements of environmental protection policies, the waste gas treatment equipment needs to be operated continuously online in the production process, otherwise the air pollution caused in the production process will face huge fines. In case of leakage of desulfurization tower pipeline or desulfurization tower equipment, it is necessary to stop production immediately for repair. However, if the plugging process of desulfurization tower is too complex or the repair time is too long, it will seriously affect the production and bring huge losses to the enterprise benefits.
