Kuongorora kupfupi kwemaitiro ekuwedzera chiyero chekuridza ladle (2)

(Mufananidzo) GW akatevedzana slit type inofema zvidhinha

Iyo yepasi yekuvhuvhuta mwero weladle ndiyo vimbiso yekugadzirwa kwakatsetseka. Iyo yakareba-yakareba mhepo-inopindirwa zvidhinha ndiyo vimbiso yekuvhuvhuta kwepamusoro. Nezve nzira yekuvandudza chiyero chekuridza ladle, isu takaongorora kubva pakuona kwe optimization yepasi-inoputika ventilating zvidhinha, (ona chikamu chakapfuura kuti uwane ruzivo), mune ino chinyorwa, isu tinoongorora kubva pamaonero ekuwedzera hupenyu hwezvidhinha zvinofefetera.

1. Shandisa zvakanakisisa zvinhu zvose kuti uwedzere kushanda kwezvidhinha zvinofema

Kuyerera kukuru kwepasi-kuvhuvhuta gasi kuchawedzera kukukurwa kwepasi-kuvhuvhuta ventilating zvidhinha. Nokudaro, kana zvidhinha zvinoputika pasi-pasi zviri kushandiswa, zvinotarisirwa kunyatso kudzora kuyerera kwegesi pamatanho akasiyana.

Naizvozvo, panguva yekubata-bata, gasi rinobva ravhurwa kuti rivhurike pasi, kuitira kuti simbi inotonhora inopinzwa mugero remhepo inonyungudutswa pasi pekunyudzwa kwesimbi yakanyungudutswa yakanyungudutswa, kuitira kudzivirira kuvharika kutsva kwegwara remhepo. nekuda kwekushisa kwepamusoro uye static pressure yesimbi yakanyungudutswa. Kurudzira kufambira mberi kwakanaka kwekuvhuvhuta pasi;

Kufuridza nekumanikidza kwakanyanya, ndiko kuti, shandisa 1.5-1.8 MPa yakakwira-kudzvanywa gasi kuvhuvhuta simbi yakanyungudutswa mune yakatsemurwa kunze kwenzira yemhepo mukati me3-5 s (kazhinji 2-3 nguva) kana ichivhuvhuta pasi. Mwero wekuvhuvhuta ungangowedzera ne2.5% -3%.

Panguva yekushandiswa, nguva dzose cherechedza kubatanidzwa kwepombi yegesi. Kana iyo yejoini ichidonha, inofanirwa kugadziriswa nekukurumidza kudzivirira kudzvanywa kwepombi kubva pakuderedzwa nekuda kwekubuda kwegasi uye kutadza kuvhuvhuta kwepasi.

Rekodha zvakasara ukobvu hwe zvidhinha zvinokwanisika nemhepo mushure mekusunungura chero nguva, kuitira kuti pasi-inoputika mhepo-inoputika zvidhinha inogona kushandiswa kusvika pamwero mukuru uye hupenyu hwayo hwebasa hunogona kurebeswa pasi pechikonzero chekushandiswa kwakachengeteka.

2. Kuchengetedza kwakakodzera

Munguva yekudurura, ladle haigone kuvhuvhuta pasi, saka huwandu hukuru hwekupinza kwesimbi hunoitika panguva ino. Mushure mekudururwa, tembiricha yemukati yeladhi inodonha zvakanyanya, uye pasi-inopeperetswa nemhepo-inopindika zvidhinha inova concave mushure mekusvibiswa. Kuti udzivise kusimba nekukurumidza kwesimbi yakaunganidzwa, iyo ladle inofanirwa kukandwa nekukurumidza uye inert gasi sosi senge nitrogen kana argon inofanira kuvhurwa panguva imwe chete. Dzora kudzvanywa kwemhepo mukati meiyo 0.8-1. 0 MPa (yezvigayo zvakawanda zvesimbi), uye pfutidza simbi isina kusimba mumhepo duct uye simbi yakaunganidzwa muchikamu chakadzoreredzwa chepasi-inovhuvhuta mhepo-inopindika zvidhinha. Mhedzisiro yekuchenesa uye kuchengetedza kwemhepo nzira yezvidhinha inofefetera inogona kukurudzira kushanda kwakanaka kwekurova kunotevera. To

Dzimwe nguva nekuda kweiyo rhythm yekugadzira uye zvimwe zvikonzero, nguva yekumirira yakareba, kana pasi-inovhuvhuta ventilating zvidhinha kushanda pamusoro yakafukidzwa yasara simbi slag, uye pamusoro inofanira kucheneswa. Shandisa okisijeni kana musanganiswa weokisijeni uye gasi remarasha kupisa simbi yakasara pamusoro, uye panguva imwechete vhura iyo gasi sosi kuti ivhuvhute kumashure, pfutidza simbi seepage slag mumhepo ndima uye zvikamu zvakadzokororwa, uye dzivirirawo simbi yakasara uye zvakasara panguva yekuchenesa Yakafuridzirwa mumhepo zvakare. Iyi mhando yematanho ekugadzirisa akakosha kune inodiwa yekunatsa maitiro.
