[XJY Inotungamira Innovation]: Yakanakisa kushandiswa kwebhegi guruva rekubvisa tekinoroji mukuputika kwechoto gasi kubvisa guruva
Pasi pemashure ekushandisa kuchengetedza kwezvakatipoteredza uye kuchengetedza simba munzira yese-kutenderera, kusimudzira iyo kubviswa kweguruvatekinoroji yeblast furnace gasi uye kusimbisa guruva rekubvisa mhedzisiro yeblast furnace gasi yave nzira isingadzivisiki yekuvaka kwechizvino uye kusimudzira maindasitiri ane hukama. Nekuenderera mberi kwekuvandudza uye kushandiswa kweiyo blast furnace gasi dedusting tekinoroji, tekinoroji yekubvisa uye yekuchenesa tekinoroji yakagadziridzwa kubva pakunyorova kusvika kune yakaoma dedusting (kusanganisira bhegi dedusting, electrostatic dedusting, nezvimwewo). Kubva pane izvi, kutora Kubviswa kweBag Dust tekinoroji semuenzaniso, kutanga nekutarisa kwayo kwakabatana, kushandiswa kwebhegi guruva rekubvisa tekinoroji mumoto wefurnace gasi kubvisa guruva kunoongororwa, uye matambudziko aripo anoiswa pamberi.
1.Overview yebhegi guruva rekubvisa tekinoroji
Pasi pemashure ekuita kuvaka kwekuchengetedza kwezvakatipoteredza uye kuvaka-kuchengetedza zviwanikwa munzira-yakatenderedza, tekinoroji yekubvisa huruva yebhegi yakawana zvimwe mhedzisiro yebudiriro, uye tekinoroji yemidziyo yayo, otomatiki yekudzora tekinoroji, masevhisi echigadzirwa, system accessories, yakakosha fiber sefa zvinhu zvakagadziridzwa kune akasiyana madhigirii.
2.Application Mechanism ye bag Dust Removal Technology muBlast Furnace Gasi Kubviswa Dust
2.1. Kuunganidzwa kwesefa zvinhu zve Bag Sefa
Kana iyo bhegi sefa tekinoroji ikaiswa kuchenesa uye kubvisa guruva mukuputika kwevira gasi, iyo sefa zvinhu mubhegi sefa inounganidza zvidimbu zveguruva kuburikidza neinertial kudhumhana mhedzisiro, electrostatic effect, screening effect, diffusion effect uye gravity sedimentation effect.
Semuenzaniso, kana zvidimbu zvakakura zveguruva muchoto chinoputika zviri pasi pechiito chekuyerera kwemhepo uye padyo nefiber trap yebhegi sefa, zvinoyerera nekukurumidza. Izvo zvimedu zvakakura zvichatsauka kubva pamhepo yekuyerera pasi pekuita kwesimba re inertia uye kuenda kumberi nenzira yekutanga, uye kudhumhana nemateya mafiibhi, ayo anove akasimba pasi pekuita kwekuteya fiber sefa. Iye zvino zvidimbu zveguruva zvinosefa. Panguva imwecheteyo, kana mafambiro emhepo achipfuura nepasefa zvinhu zvebhegi sefa, iyo electrostatic mhedzisiro inoumbwa pasi pechiito chesimba rekukwesha, rinoita kuti guruva ribhadharwe, uye guruva zvidimbu zvinoshambadzirwa uye zvakavharirwa pasi pechiito chekugona mutsauko uye simba reCoulomb.
2.2. Kuunganidzwa kweDust Layer muBag Dust Collector
Kazhinji, mabhegi emasefa ebhegi sefa anogadzirwa neshinda. Munguva yekucheneswa uye kusefa, guruva zvidimbu zvinogadzira "bridging phenomenon" mumavoid eiyo sefa zvinhu mambure, ayo anozodzikisa saizi yepore yemambure emidziyo uye zvishoma nezvishoma inogadzira guruva. Nekuti iyo dhayamita yehuruva zvidimbu muguruva mutsetse idiki pane dhayamita yemafirita emidziyo kusvika kune imwe nhanho, sefa uye kubira kweguruva rinoonekwa, uye guruva rekubvisa mhedzisiro yebhegi sefa inovandudzwa.
2.3. Kucheneswa uye kubviswa kwe blast furnace gasi guruva nebhegi sefa. Kazhinji, iyo particle size yekugovera yeutsi neguruva mukuputika kwevira gasi kunobva padiki kusvika kuhombe. Naizvozvo, mukuita kwebhegi kusefa mashandiro, iyo mhepo ine guruva zvidimbu ichapfuura nepasefa zvinhu zvebhegi sefa. Mukuita uku, iwo makuru eguruva zvidimbu anozosiiwa musefa zvinhu kana pamusoro pesefa zvinhu mambure negiravhiti, nepo diki guruva zvidimbu (zvisingasviki jira resefa risina) richamanikidzwa kukanganisa, skrini kana kusiya mufurafura yezvinhu tafura. Iyo yepamusoro inosiiwa isina chinhu chejira resefa neBrownian motion. Nekuenderera mberi kwekuunganidzwa kwehuruva zvidimbu zvakabatwa nesefa zvinhu, guruva rinoumbwa pamusoro pebhegi resefa, uye kusvika pamwero wakati, inove "sefa membrane" yebhegi resefa kuti iwedzere kucheneswa uye kubvisa guruva mhedzisiro yebhegi sefa.
3.Kushandisa kwe bhegi dedusting teknolojia mu blast furnace gasi dedusting
3.1. Pfupiso yeApplication
Iyo bhegi guruva rekubvisa sisitimu inonyanya kuumbwa nekumashure-kuvhuvhuta madota ekubvisa system, control system, semi-yakachena gasi pipeline system, semi-yakachena gasi kuchengetedza tembiricha system, madota ekutakurisa uye madota ekuburutsa system, etc. Inoshandiswa kuona kucheneswa uye kubviswa kweguruva kwekuputika kwechoto gasi.
3.2. Kushandiswa kweBag Dust Kuunganidza System
3.2.1. Kushandiswa kweBack-blown Soot Cleaning System
Mugadziriro yekubvisa guruva resaga, gadziriro yekubvisa dota inopfurwa neshure inogona kupatsanurwa muzvikamu zviviri: hurongwa hwekubvisa madota anodzvanyirirwa neshure uye nitrogen pulse back-blown ash remove system. The pressurized back-blown ash remove system is an internal filter mode. Kana gasi rine guruva richiyerera richienda kunze kuburikidza nebhegi resefa yebhagi refagi, mhepo inoyerera ichachinja nzira pasi pechiito chemashure-inoputirwa madota ekubvisa system, ichiziva kubuda kwemhepo kubva kunze kuenda mukati, nokudaro kuzadzisa chinangwa chekubvisa guruva kuburikidza nekuunganidzwa kwebhegi resefa. Iyo nitrogen pulse back-blown dust cleaning system ndeyekuyerera gasi rine zvidimbu zveguruva kubva pasi kuenda kunze kwepamusoro pebhegi resefa. Paunenge uchisimbisa basa rehupfu hweguruva, kuunganidza guruva kunze kwepamusoro pebhegi resefa rinogona kucheneswa nenzira yepulse valve. Kuti uwedzere basa rekudzokera shure-kuvhuvhuta ash-cleaning system, kuongororwa kwakananga kunofanira kuitwa maererano nemamiriro ezvinhu chaiwo mukushandiswa kwayo.
3.2.2. Kushandiswa kweDifferential Pressure Detection System
Mukuita kwekushandisa kwebhegi sefa, zvakakosha kwazvo kuve nechokwadi chekuchengetedza uye kugadzikana kweiyo musiyano yekumanikidza yekuona system. Kazhinji, iyo yekudzvanya mutsauko yekuona mapoinzi inonyanya kugoverwa mugasi inlet uye pombi yekubuda uye yakachena gasi kamuri yebhokisi rebhokisi. Iyo sainzi uye kurongeka kweiyo system yekumisikidza ndiyo kiyi yekuona kurongeka uye kurongeka kwekusiyanisa kudzvanywa kwechiratidzo chekuonekwa, uye kuonesa kurongeka ndiyo nzira yakakosha yekuvandudza kunaka kwekuchengetedza guruva muunganidzi, pamwe nenzira yakakosha yekuvandudza hupenyu hwebasa remabhegi emasefa, kuvandudza mhando yehurongwa uye kuderedza kushandiswa kwesimba.
3.2.3. Kushandiswa kweSemi-yakachena Gasi Chengetedza Temperature Control System
Mukuita kwekuputika kwechoto kunyunguduka mumabhizinesi esimbi nesimbi, gasi rinogadzirwa neinoputika vira remidziyo inova "semi-yakachena gasi" pasi pechiito chekunatsa giravhiti uye kubvisa guruva. Panguva imwecheteyo, semi-yakachena gasi inopinda mubhegi sefa nevharuvhu isingaoni, shavishavi yevharuvhu inonhonga huruva uye semi-yakachena gasi pombi yekubvisa huruva. Kazhinji, kana semi-yakachena gasi inopinda muguruva rekuunganidza chubhu, tembiricha yegesi inoshanduka kune imwe nhanho, ndiko kuti, kupisa. Nekuwedzera kwekushisa, kuyerera kwemhepo kunoparadza bhegi resefa mumudziyo weguruva uye kupisa bhegi resefa. Naizvozvo, kuti uve nechokwadi chekuchengetedza tembiricha, zvinodikanwa kuisa semi-yakachena gasi kuchengetedza tembiricha yekudzora tembiricha yekudzora tembiricha.
3.2.4. Mamwe Maitiro Ekushandisa
Kuti uve nechokwadi chekutamba kwakazara kwebasa rebhegi sefa uye kuderedza kushandiswa kwesimba mukushanda. Mukuita kwekunyorera, zvinodikanwa kuti usarudze nesainzi vharuvhu yebhokisi rekuunganidza guruva kuti ive nechokwadi chekuchengetedza uye kusimba kwehurongwa uye kudzivirira kubuda kwegasi mukubvisa guruva. Kazhinji, kana kudzvinyirirwa kwehurongwa hwemambure kushanduka uye kune migumisiro yakaipa pamavharuvhu evhavha, iyo yakatwasuka ndiro guruva shavishavi mavharuvhu kana kuburikidza nekuisa guruva maburi ekuchenesa inogona kushandiswa kusimbisa shavishavi mavharuvhu.
4.Mashoko okupedzisa
Mukunyungudutsa kwemaindasitiri, zvakakosha zvikuru kuvandudza mwero wekushandiswa kwekuputika kwechoto gasi zviwanikwa, kuderedza kusvibiswa kwezvakatipoteredza kwekuputika kwegasi remoto, kuvandudza hupfumi hwemabhizinesi, uye kusimudzira makwikwi ekusimudzira emabhizinesi.
