Popeza ndi gwero lamphamvu lachikhalidwe mdziko muno, malo ofunikira a malasha sangagwedezeke kwakanthawi kochepa. Pansi pa njira yoteteza chilengedwe ndi kuchepetsa utsi, kulimbikitsa ndi kugwiritsa ntchito ufa woyera wa malasha ndi njira imodzi yofunika kwambiri yolimbikitsira kusintha kwa mphamvu. Guilin Hongcheng HMM bowl mill, yokhala ndi zabwino zambiri monga kugwira ntchito bwino, kuteteza chilengedwe, ndi luntha, idzathandiza kupanga ufa wa malasha a boiler ndikulimbikitsa chitukuko chobiriwira, chanzeru, komanso chokhazikika cha makampani opanga mphamvu.
1. Kusankha ufa wa malasha wa boilers
1）Boiler yamagetsi: Maboiler amagetsi amagwiritsidwa ntchito makamaka popanga magetsi m'mafakitale amagetsi, kupereka zida zamagetsi zosinthira mphamvu zamakemikolo kukhala mphamvu yotentha ya nthunzi kuti ikhale ndi mafuta ambiri. Amakhala osinthika kwambiri ku mitundu ya malasha, koma amafunika kutentha pang'ono komanso zinthu zosinthasintha zomwe zimakhala mu uvuni, pomwe amachepetsa kuchuluka kwa zodetsa monga sulfure ndi phulusa. Mphamvu yamagetsi nthawi zambiri imakhala pakati pa 5500-7500 kcal/kg.
2）Ma boiler a mafakitale: Ma boiler a mafakitale amagwiritsidwa ntchito makamaka popereka nthunzi popanga chakudya, nsalu, mankhwala, mankhwala ndi mabizinesi ena, ndipo angagwiritsidwenso ntchito potenthetsera m'mizinda. Nthawi zambiri, phulusa lochepa, sulfure yotsika, phosphorous yotsika, zinthu zosinthasintha, ndi malasha osaphika kapena malasha otsukidwa amasankhidwa ngati zopangira, ndipo gawo lina la zotsukira ndi zoletsa moto zimawonjezedwa.
2. Njira zogwiritsira ntchito ufa wa malasha pa boilers
1）Kukonza ufa wa malasha: Sankhani malasha oyenera ngati zopangira kutengera zofunikira pakuyaka ndi mawonekedwe a malasha a boiler; Malasha osaphika amaphwanyidwa mzidutswa tating'onoting'ono ndi chotsukira kenako nkutumizidwa ku mphero ya malasha kuti akaphwanyidwe kuti akonze ufa wa malasha womwe umakwaniritsa zofunikira pakuyaka kwa boiler.
2） Kutumiza ufa wa malasha: Ufa wa malasha wokonzedwa umatumizidwa ku silo ya ufa wa malasha pafupi ndi boiler kudzera mu njira yotumizira mpweya (monga kutumiza mpweya kapena kutumiza nayitrogeni), kenako umalowetsedwa mu choyatsira ufa wa malasha mwanjira yochuluka komanso yofanana kudzera mu chodyetsa malasha kapena zida zina zodyetsera malasha malinga ndi zofunikira za boiler.
3）Kuthira ufa wa malasha: Ufa wa malasha umasakanizidwa ndi mpweya (mpweya woyamba ndi wachiwiri) mu chotenthetsera ufa wa malasha, umatenthedwa bwino kenako umayatsidwa usanalowe mu uvuni wa boiler. Panthawi yothira, tinthu ta malasha tophwanyika timayatsa ndi kutentha kwambiri, zomwe zimapangitsa kuti kutentha kukhale kwakukulu, zomwe zimapangitsa kuti kutentha kukhale kwakukulu.
3. Ubwino wogwiritsa ntchito ufa wa malasha pa ma boiler
1）Kuwongolera magwiridwe antchito oyatsa: Pambuyo popera, kukula kwa tinthu ta ufa wa malasha kumachepa, ndipo malo a pamwamba amawonjezeka ndikukhala ofanana, zomwe zimapangitsa kuti mankhwala azigwira ntchito panthawi yoyatsa ndipo zimathandiza kuti ufa wa malasha ugwirizane bwino ndi mpweya, zomwe zimapangitsa kuti kuyatsa kukhale bwino. Nthawi yomweyo, liwiro la kuyatsa limakhala lachangu, kuchuluka kwa kutentha kumakhala kwakukulu, ndipo mphamvu ya kutentha imawonjezekanso.
2） Zimathandiza kusunga mphamvu ndi kuchepetsa utsi: Chifukwa cha mphamvu yoyaka kwambiri ya ufa wa malasha, mtundu womwewo wa ufa wa malasha ukhoza kutulutsa mphamvu zambiri zotentha, motero kuchepetsa kugwiritsa ntchito mphamvu. Kuphatikiza apo, utsi wa zinthu zoipitsa monga sulfur dioxide, nitrogen oxides, ndi tinthu tating'onoting'ono tomwe timapangidwa ndi ufa wa malasha ndi wochepa, zomwe zimathandiza kuchepetsa kuipitsa chilengedwe.
3）Kukonza kukhazikika kwa ntchito: Lawi lomwe limapangidwa panthawi yoyaka ufa wa malasha limakhala lokhazikika komanso loyaka mofanana, zomwe zimathandiza kulimbitsa kukhazikika kwa ntchito ya boiler. Pakadali pano, ma boiler amakono amakampani nthawi zambiri amagwiritsa ntchito njira zowongolera zokha, zomwe zimatha kuwongolera molondola magawo monga kuchuluka kwa chakudya cha ufa wa malasha ndi kuchuluka kwa mpweya, kuonetsetsa kuti boiler ikugwira ntchito bwino.
4）Ubwino waukulu pazachuma: Ma boiler oyaka malasha ali ndi zotsatira zabwino zopulumutsa mphamvu poyerekeza ndi ma boiler achikhalidwe, zomwe zimatha kusunga malasha ambiri ndikuchepetsa ndalama zopangira. Kuphatikiza apo, boiler ya ufa wa malasha imagwiritsa ntchito ukadaulo wapamwamba woyaka ndi njira yowongolera, zomwe zingathandize kuti boiler igwire bwino ntchito komanso mokhazikika, potero kuchepetsa kuwononga mafuta ndi nthawi yopuma.
4. HMM series bowl coal mill
Chipinda chopukusira malasha cha HMM series ndi chipangizo chopukusira malasha chomwe chimagwira ntchito bwino kwambiri, chosavuta kugwiritsa ntchito, chosinthika, chosunga mphamvu komanso chosamalira chilengedwe chomwe chinapangidwa ndi Guilin Hongcheng kutengera kufunikira kwa msika komanso mawonekedwe a ufa wa malasha. Chapangidwa makamaka kuti chipukute, kuumitsa ndi kusanja malasha opangidwa mwachindunji kuchokera ku ma boiler, ndipo ndi chisankho chabwino kwambiri chokonzekera ufa wa malasha m'ma boiler amagetsi ndi ma boiler amafakitale.
01, Ubwino ndi Makhalidwe
1. Mphero ya malasha m'mbale imatha kusinthasintha mosavuta ndipo imatha kukonza mitundu yosiyanasiyana ya malasha, kuphatikizapo malasha otsika mtengo komanso otsika mtengo, komanso phulusa lambiri ndi malasha onyowa kwambiri;
2. Kugwedezeka kochepa, palibe chifukwa chogwiritsa ntchito maziko opopera masika, okhala ndi mota yayikulu yokhala ndi mphamvu zochepa kuposa mphero zina zamakala zapakati, zomwe zimathandiza kusunga mphamvu ndi kuchepetsa kugwiritsa ntchito mphamvu;
3. Chopukusira sichikhudzana mwachindunji ndi chopukusira mbale, chitha kuyatsidwa popanda katundu, chili ndi malo ambiri osinthira katundu, ndipo chimaloledwa kugwira ntchito pa 25-100% ya katundu;
4. Kapangidwe kake ndi kosavuta komanso koyenera, kopanda ngodya zofewa kuti ufa usungidwe. Kulimba kwakukulu kwa mphepo imodzi ndi kochepera 4.5Kpa (m'malo osalala), ndipo cholekanitsa chimatha kupirira kupsinjika kwa 0.35Mpa;
5. Chopukusira chikhoza kusinthidwa mwachindunji kuti chikonzedwe ndi kusinthidwa. Mbale iliyonse yopukusira mbale imalemera pafupifupi 25kg ndipo imatha kusunthidwa ndi manja. Chipangizo chopukusira chokweza chimakhala kunja kwa thupi lolekanitsa, zomwe zimapangitsa kuti kukonza kukhale kosavuta;
6. Chopukutira chopukutira chimapangidwa ndi chopukutira cha alloy chosatha, chomwe chimakhala ndi moyo wautali ndipo chimatha kupukutidwa mobwerezabwereza nthawi 5-6 mutachipukuta, zomwe zimachepetsa ndalama zogwirira ntchito;
7. Kugwiritsa ntchito njira yowongolera yokha ya PLC, yomwe ingathandize kuyendetsa patali, kugwiritsa ntchito mosavuta, kukonza kosavuta, ndikuchepetsa ndalama zogwirira ntchito;
8. Yochepa kukula, yocheperako kutalika, komanso yopepuka, maziko ake a konkriti amangofunika kulemera kowirikiza kawiri ndi theka kuposa kulemera kwa makina onse, zomwe zimapangitsa kuti ndalama zogulira zonse zikhale zochepa.
