Inzwa yokucindezela kwezinga lokushisa eliphezulu
Iyini inzwa yokucindezela kwezinga lokushisa eliphezulu?
Inzwa yomfutho wezinga eliphezulu lokushisa iyinzwa ye-piezoelectric ekwazi ukukala izingcindezi ezingeni lokushisa elingashintshi elingafika ku-700°C (1.300°F).Isebenza njengesistimu ye-spring-mass, izinhlelo zokusebenza ezijwayelekile zihlanganisa izinqubo lapho ukucindezela okuguquguqukayo kufanele kulinganiswe futhi kulawulwe.Ngenxa yekristalu eyakhelwe ngaphakathi i-PiezoStar, inzwa yengcindezi yezinga eliphezulu imelana nezinga lokushisa elifinyelela ku-1000°C (1830°F) esikhathini esifushane.Ngobuchwepheshe obuhlukile kanye nesinxephezelo sokusheshisa esakhelwe ngaphakathi, umsindo ophansi nokunemba okuphezulu kufinyelelwa.Ikhebuli yomugqa oqinile ehlukanisiwe ikakhulukazi eklanyelwe amazinga okushisa aphakeme kakhulu ixhuma inzwa ne-amplifier yokushaja.
Zisetshenziselwa ini izinzwa zengcindezi ephezulu yokushisa?
Izinzwa zengcindezi yokushisa okuphezulu zisetshenziselwa ukulinganisa nokulawula izinqubo zokuvutha okuguquguqukayo, isibonelo kumaturbine wegesi kanye nezinhlelo zokusebenza ezifanayo ze-thermoacoustic.Bathwebula ngokunembile ukucindezela okungase kube yingozi nokudlidliza ukuze kuthuthukiswe ukusebenza kwesistimu.
Lakheka kanjani iketango lokulinganisa lezinzwa zengcindezi yezinga lokushisa eliphezulu?
Ngaphandle kwezinzwa ngokwazo, izikhulisamandla zokushaja ezihlukene kanye nezintambo eziqinile ezinomsindo ophansi kanye ne-softline ziqinisekisa ukuthi kufinyelelwa ikhwalithi yokulinganisa ephezulu.Ukwengeza, izingxenye eziqinisekisiwe zangaphambili zisetshenziselwa ukusetshenziswa ezindaweni ezinokhahlo.
Yiziphi izinhlobo zezinzwa zomfutho wezinga lokushisa eliphezulu ezikhona?
Izinzwa zengcindezi yezinga eliphezulu lokushisa zitholakala ngezinhlobonhlobo eziningi zezinguqulo, phakathi kwazo okuhlukile okuncane nokungasindi ngezinjongo zocwaningo nentuthuko.Ngokuya ngezidingo zohlelo lokusebenza oluthile, ubude bekhebula ngalinye kanye nezinhlobo zokuxhuma zingenzeka.Ngaphezu kwalokho, okuhlukile okuqinisekisiwe (ATEX, IECEx) kusetshenziswa ezindaweni eziyingozi.
Izinzwa zokucindezela kwezinga lokushisa eliphezuluzinikezelwe ukusetshenziswa ezindaweni zokushisa eziphezulu.Njengoba sonke sazi ukuthi izinzwa zokucindezela ezivamile azikwazi ukusebenza endaweni yokushisa ephezulu isikhathi eside uma kungekho zinyathelo zokuzivikela ezithathwayo.
Ukuhlinzeka ngezixazululo zokufaka isicelo sokushisa okuphezulu, izinzwa zokucindezela kokushisa okuphezulu zithuthukiswa ngaphandle kwezinyathelo ezengeziwe ezithathwe.Lolu hlobo lwenzwa lungasebenza ekushiseni okungafika ku-200℃.Idizayini yayo eyingqayizivele yesinki yokushisa inciphisa ukushisa ngezinga elikhulu, okuvikela kahle inzwa ikakhulukazi umnyombo ekuhlaseleni okungazelelwe okushisayo kwe-medium ephezulu.
Kodwa uma ingcindezi evamile izinzwa zisetshenziswa isicelo esinjalo kunokubaizinzwa zokucindezela kokushisa okuphezulu, khona-ke kufanele kuthathwe izinyathelo zokuzivikela ukuze kugwenywe ukulimala kwesifunda, izingxenye, indandatho yokuvala uphawu kanye nomgogodla.Ngezansi kunezindlela ezintathu.
1. Uma izinga lokushisa lendawo yokulinganisa liphakathi kuka-70 no-80℃, engeza irediyetha kunzwa yokucindezela kanye nendawo yokuxhuma ukuze wehlise izinga lokushisa ngokufanele ngaphambi kokuthi into ephakathi nendawo ithintane ngokuqondile nethuluzi.
2. Uma izinga lokushisa eliphakathi nendawo elilinganisiwe liba ngu-100°C~200°C, faka indandatho yecondenser endaweni yokuxhuma ingcindezi bese wengeza irediyetha, ukuze ukushisa kupholiswe kokubili ngaphambi kokuthintana ngqo nenzwa yokucindezela. .
3.Ukulinganisa izinga lokushisa eliphezulu kakhulu, ishubhu eliqondisayo linganwetshwa bese lixhunywa kunzwa yokucindezela, noma kokubili ishubhu le-capillary kanye ne-radiator kungafakwa ukuze kuzuzwe ukupholisa okuphakathi.
