[XJY Leads Innovation]: Kugwiritsa ntchito bwino kwambiri ukadaulo wochotsa fumbi mu ng'anjo yotulutsa fumbi lamoto

Pansi pakugwiritsa ntchito chitetezo cha chilengedwe ndi kupulumutsa mphamvu mozungulira mozungulira, kukweza ukadaulo wochotsa fumbi wa gasi wang'anjo yophulika ndi kulimbikitsa kuchotsedwa kwa fumbi la mpweya wophulika wa ng'anjo yakhala njira yosapeŵeka ya zomangamanga zamakono ndi chitukuko cha mafakitale okhudzana. Ndi luso mosalekeza ndi ntchito luso blast ng'anjo dedusting ukadaulo, dedusting ndi kuyeretsa ukadaulo wake wayamba kuchokera kunyowa dedusting kuti youma dedusting (kuphatikiza thumba dedusting, electrostatic dedusting, etc.). Kutengera izi, kutenga ukadaulo wochotsa fumbi lachikwama monga mwachitsanzo, kuyambira ndikuwunikira kofananira, kugwiritsa ntchito ukadaulo wochotsa fumbi lachikwama pakuchotsa fumbi lamoto wamoto kumawunikidwa, ndikuwunika mavuto omwe alipo.

1.Chidule chaukadaulo wochotsa fumbi la thumba

Pansi pakugwiritsa ntchito zomanga zoteteza zachilengedwe ndi zomanga zopulumutsa zinthu mozungulira, ukadaulo wochotsa fumbi wa thumba wapeza zotsatira zina zachitukuko, ndiukadaulo wa zida zake, ukadaulo wowongolera zokha, ntchito zopangira, zida zadongosolo, zida zapadera zosefera za CHIKWANGWANI. zakonzedwa mosiyanasiyana.

2.Njira Yogwiritsira Ntchito ya Tekinoloji Yochotsa Fumbi mu thumba mu Blast Furnace Gasi Kuchotsa

2.1. Kutolera zosefera za thumba zosefera

Pamene luso thumba fyuluta ntchito kuyeretsa ndi kuchotsa fumbi mu kuphulika ng'anjo mpweya, zinthu fyuluta mu thumba fyuluta adzasonkhanitsa tinthu fumbi kudzera inertial kugunda kwenikweni, electrostatic kwenikweni, screening tingati, diffusion zotsatira ndi mphamvu yokoka sedimentation.

Mwachitsanzo, tinthu tating'onoting'ono ta fumbi la ng'anjo yophulikayo zikamayendetsedwa ndi mpweya komanso pafupi ndi msampha wa thumba la thumba, zimayenda mwachangu. Tinthu tating'ono ting'onoting'ono timapatuka panjira yoyendetsera mpweya pansi pa mphamvu ya inertia ndikupita patsogolo panjira yoyambira, ndikugundana ndi ulusi wokokera, womwe udzakhala wolimba pansi pa kutsekereza fyuluta ya fiber. Tsopano fumbi particles amasefedwa. Pa nthawi yomweyo, pamene mpweya akudutsa zinthu fyuluta thumba fyuluta, mphamvu electrostatic aumbike pansi pa zochita za mikangano mphamvu, zomwe zimapangitsa fumbi particles mlandu, ndi particles fumbi ndi adsorbed ndi kutsekeredwa pansi zochita za kuthekera kusiyana. ndi mphamvu ya Coulomb.

2.2. Kutoleredwa kwa Dust Layer mu Thumba Lotolera Fumbi

Nthawi zambiri, matumba a fyuluta a thumba amapangidwa ndi ulusi. Pakuyeretsedwa ndi kusefera, tinthu tating'onoting'ono timapanga "browging phenomenon" mu voids ya ukonde wazinthu zosefera, zomwe zimachepetsa kukula kwa pore wa ukonde wazinthu zosefera ndikupanga fumbi pang'onopang'ono. Chifukwa m'mimba mwake wa fumbi wosanjikiza fumbi ndi wocheperako kuposa m'mimba mwake wa ulusi wa zinthu zosefera mpaka pamlingo wina, fyuluta ndi kutsekeka kwa fumbi wosanjikiza zimawonekera, ndipo zotsatira zochotsa fumbi za thumba zosefera zimakhala bwino.

2.3. Kuyeretsa ndi kuchotsa fumbi la gasi lamoto ndi thumba fyuluta. Nthawi zambiri, kukula kwa tinthu ting'onoting'ono kwa utsi ndi fumbi mu mpweya wophulika wa ng'anjo kumachokera ku zazing'ono mpaka zazikulu. Choncho, pogwira ntchito ya fyuluta ya thumba, mpweya wotuluka mu fumbi umadutsa muzosefera za thumba. Pochita izi, tinthu tating'ono ting'onoting'ono timasiyidwa muzosefera kapena pamwamba pa ukonde wazinthu zosefera ndi mphamvu yokoka, pomwe tinthu tating'onoting'ono ta fumbi (zocheperako zosefera) zidzakakamizika kukhudza, kuwonekera kapena kuchoka. tebulo lazinthu zosefera. Kumwamba kumasiyidwa opanda nsalu yosefera ndi Brownian motion. Ndi kudzikundikira kosalekeza kwa tinthu tating'ono ting'onoting'ono totengedwa ndi zosefera, thumba la fumbi lidzapangidwa pamwamba pa thumba la fyuluta, ndipo pamlingo wina, lidzakhala "sefa nembanemba" ya thumba la fyuluta kuti liwonjezere kuyeretsa ndi fumbi. kuchotsa zotsatira za thumba fyuluta.

3.Kugwiritsa ntchito ukadaulo wochotsa thumba mu blast furnace gas dedusting

3.1. Chidule cha Ntchito

Dongosolo lochotsa fumbi la thumba limapangidwa makamaka ndi njira yochotsera phulusa lakumbuyo, makina owongolera, mapaipi apaipi oyeretsera mpweya, makina otetezera kutentha kwa gasi, kutengera phulusa ndi kutsitsa phulusa, ndi zina. Amagwiritsidwa ntchito kuzindikira kuyeretsedwa. ndi kuchotsa fumbi la gasi wophulika ng'anjo.

3.2. Kugwiritsa ntchito Bag Fumbi Collection System

3.2.1. Kugwiritsa Ntchito Mwaye Wowombetsa M'mbuyo

Mu dongosolo lochotsa fumbi la thumba, njira yochotsera phulusa yowombedwa kumbuyo ikhoza kugawidwa m'magulu awiri: njira yochotsera phulusa yowombedwa kumbuyo ndi nitrogen pulse back-blown phulusa. The pressurized back-blown phulusa kuchotsa phulusa ndi mkati fyuluta mode. Pamene mpweya wafumbi umatuluka kunja kudzera mu thumba la fyuluta ya thumba la thumba, kutuluka kwa mpweya kudzasintha njira pansi pa machitidwe a kuchotsa phulusa lakumbuyo, kuzindikira kutuluka kwa mpweya kuchokera kunja kupita mkati, motero kukwaniritsa cholinga chochotsa fumbi kupyolera mu kusonkhanitsa. za thumba la fyuluta. Dongosolo la nitrogen pulse back-blown fumbi limatulutsa mpweya wokhala ndi fumbi kuchokera pansi kupita kunja kwa thumba la fyuluta. Pamene kulimbikitsa gawo la fumbi la fumbi, kusonkhanitsa fumbi kunja kwa thumba la fyuluta kungathe kutsukidwa pogwiritsa ntchito valve pulse. Pofuna kukulitsa udindo wa dongosolo lotsuka phulusa lakumbuyo, kusanthula kwapadera kuyenera kupangidwa molingana ndi momwe zinthu zilili pakugwiritsa ntchito kwake.

3.2.2. Kugwiritsa Ntchito Differential Pressure Detection System

Pogwiritsira ntchito fyuluta ya thumba, ndizofunikira kwambiri kuonetsetsa chitetezo ndi kukhazikika kwa njira yake yodziwira kuthamanga kwa kusiyana. Nthawi zambiri, malo ozindikira kusiyana kwapakati amagawika kwambiri polowera gasi ndi mapaipi otulutsira komanso chipinda choyera cha gasi. Sayansi ndi zomveka za dongosolo unsembe ndiye chinsinsi kuonetsetsa kulondola ndi kulondola kwa kusiyana kuthamanga chizindikiro kuzindikira, ndi kudziwika kulondola ndi njira kiyi kupititsa patsogolo khalidwe la fumbi otolera yokonza, komanso njira yofunika kupititsa patsogolo utumiki. moyo wa matumba fyuluta, kusintha dongosolo dongosolo ndi kuchepetsa kugwiritsa ntchito mphamvu.

3.2.3. Kugwiritsa ntchito Semi-clean Gas Safety Temperature Control System

Popanga ng'anjo yophulika m'mabizinesi achitsulo ndi zitsulo, mpweya wopangidwa ndi zida zamoto udzakhala "gasi woyeretsedwa" pansi pa kuyeretsa mphamvu yokoka ndi kuchotsa fumbi. Nthawi yomweyo, gasi wa semi-oyera amalowa mu thumba la fyuluta kudzera pa valavu yakhungu, valavu ya gulugufe wotolera fumbi ndi mapaipi a gasi osayera kuti achotse fumbi. Kawirikawiri, pamene mpweya wa semi-oyera umalowa mu chubu chosonkhanitsa fumbi, kutentha kwa mpweya kumasintha pamlingo wina, ndiko kuti, kutentha. Ndi kuwonjezeka kwa kutentha, mpweya wotuluka udzawononga thumba la fyuluta mu chosonkhanitsa fumbi ndikuwotcha thumba la fyuluta. Choncho, pofuna kuonetsetsa chitetezo cha kutentha, m'pofunika kukhazikitsa semi-oyera gasi chitetezo kutentha dongosolo kulamulira kutentha.

3.2.4. Njira Zina Zogwiritsira Ntchito

Pofuna kuonetsetsa sewero lonse la udindo wa thumba fyuluta ndi kuchepetsa mphamvu mphamvu ntchito. Pogwiritsira ntchito, ndikofunikira kuti musankhe mwasayansi valavu ya bokosi losonkhanitsa fumbi kuti muwonetsetse chitetezo ndi kulimba kwa dongosolo ndikupewa kutulutsa mpweya pochotsa fumbi. Kawirikawiri, pamene mavuto a dongosolo maukonde kusintha ndipo ali ndi zotsatira zoipa pa mavavu agulugufe, molunjika mbale fumbi mavavu gulugufe kapena mwa unsembe wa fumbi kuchotsa mabowo angagwiritsidwe ntchito kulimbikitsa gulugufe mavavu.

4.Mawu omaliza

Pakusungunula m'mafakitale, ndikofunikira kwambiri kupititsa patsogolo kuchuluka kwa kagwiritsidwe ntchito ka gasi wang'anjo yophulika, kuchepetsa kuipitsidwa kwa chilengedwe ndi mpweya wophulika wa ng'anjo, kupititsa patsogolo chuma chamabizinesi, ndikulimbikitsa chitukuko chokhazikika chamakampani.
