Tube Heating Ng'anjo-Mafakitale Osungunula Ng'anjo

Tube Kutentha ng'anjo ndi njira yotenthetsera ng'anjo yomwe imagwiritsidwa ntchito poyenga petroleum, petrochemical and chemical and chemical fiber industries, yomwe ili ndi zinthu zingapo zomwe sizipezeka muzinthu zina.ng'anjo yosungunula mafakitales.

Zofunikira:ali ndi chipinda choyaka chozunguliridwa ndi zinthu zokanira, pogwiritsa ntchito kutentha komwe kumapangidwa ndi kuyaka kwamafuta kutenthetsa zinthu za chipangizocho.

Tube Kutentha ng'anjo makhalidwe.

1) Zinthu zotenthetsera zimayenda mkati mwa chubu, choncho zimangowonjezera kutentha kwa mpweya kapena zakumwa.

(2) Kuwotchera njira yamtundu wamoto wachindunji.

(3) kuwotcha mafuta amadzimadzi okha kapena mpweya.

(4) yaitali mkombero mosalekeza ntchito, osasokonezedwa ntchito.

Mfundo Yogwirira Ntchito:

Mfundo yogwirira ntchito ya ng'anjo yotentha ya chubu ndi: mafuta amawotchedwa mu chipinda choyaka moto cha ng'anjo yotentha ya chubu (ochepa kwambiri m'chipinda choyatsira moto), ndipo kutentha komwe kumatulutsidwa kumasamutsidwa ku chubu cha ng'anjo kupyolera mu kutentha kwa cheza ndi kutentha kwa convection. kutengerapo, ndiyeno anasamutsidwa kwa sing'anga kutentha kudzera conduction kutentha kutengerapo ndi convection kutentha kutengerapo.

Mbali zazikulu

Poyerekeza ndi zida zina zoyenga mafuta, chinthu chapadera cha ng'anjo yotentha ya tubular ndikuti imatenthedwa mwachindunji ndi lawi;poyerekeza ndi ambiri mafakitale ng'anjo, chubu cha ng'anjo tubular Kutentha ndi pansi kutentha, kuthamanga ndi dzimbiri sing'anga;poyerekeza ndi boiler, sing'anga mu ng'anjo yotentha ya tubular si madzi ndi nthunzi, koma yoyaka, yophulika, yosavuta kung'ambika, yosavuta kupangira coke ndi mafuta owononga kwambiri ndi gasi, zomwe ndizo zikuluzikulu za ng'anjo yotentha ya tubular.

Kodi mbali zazikulu za ng'anjo ya chubu ndi chiyani?

Kutentha kwa ng'anjo ya ng'anjo kumaphatikizapo chubu, cholumikizira chubu cha ng'anjo ndi zida zothandizira, kapangidwe kachitsulo, ng'anjo ya ng'anjo, njira yobwezeretsa kutentha kwa zinyalala, chowotcha, soot blower, chimney, chimney baffle, ma valve agulugufe osiyanasiyana, zitseko (chitseko cha wotchi yamoto, chitseko cha manhole, kuphulika. -chitseko chotsimikizira, kuyeretsa chitseko cha dzenje ndi kutsegula chitseko cha dzenje, ndi zina zotero) ndi cholandirira chida (thermocouple casing, chubu choyezera kuthamanga, chitoliro chozimitsa moto, wolandila mpweya wa analyzer ndi wolandila doko la flue, etc.).

Kodi ng'anjo yotenthetsera chubu imagawidwa bwanji?

Malinga ndi ntchitoyo akhoza kugawidwa mu: Kutentha mtundu ndi Kutentha - reaction mtundu magulu awiri.

Kutentha mtundu chubu ng'anjo: ng'anjo mumlengalenga, depressurized ng'anjo, zosiyanasiyana fractionation tower feed feed ng'anjo, nsanja pansi reboiler ng'anjo, coking ng'anjo, reforming ng'anjo ndi hydrogenation ng'anjo ndi mitundu ina ya riyakitala (nsanja) chakudya.kutentha ng'anjo.

Kutentha - anachita mtundu chubu ng'anjo: haidrojeni kupanga ng'anjo, ethylene akulimbana ng'anjo, etc. Malinga waukulu kutentha kutengerapo akafuna anawagawa: koyera convection ng'anjo, koyera poizoniyu ng'anjo, poizoniyu - convection mtundu ng'anjo ndi iwiri mbali ng'anjo cheza ng'anjo.

Malingana ndi mtundu wa ng'anjo ukhoza kugawidwa mu: ng'anjo ya silinda,ng'anjo yowongokandi lalikulu bokosi mtundu ng'anjo magulu atatu.
