Cov txheej txheem ntawm veneer ziab tuaj yeem muab faib ua peb theem: ① theem cua sov; ② qhov tsis tu ncua - theem ziab; thiab ③ qhov poob - theem ziab.
Raws li txoj cai no, lub tshuab ziab khaub ncaws tuaj yeem tsim los ua ob- ntu ntu- ntu pem hauv ntej thiab sab nraub qaum. Cov kiv cua hauv lub tshuab ziab khaub ncaws pem hauv ntej yog siv los ntawm ntau dua - lub cev muaj zog, thaum cov nyob hauv qab siv lub zog qis dua. Ib qho qhib tau muab tso rau hauv nruab nrab ntawm cov txheej txheem kom qhuav, thiab ib qho cua txias ntxiv rau ntawm tus Tsov tus tw kawg. Axial-Flow kiv cua nqus cua txias rau hauv chav txias, qhov chaw uas nws tau coj mus rau hauv cov veneers los ntawm cov nozzles hauv lub thawv plenum; Qhov no zoo daws cov kev ntxhov siab sab hauv hauv cov laug cam thiab txo qis deformation.
Txhawm rau kom ntseeg tau tias cov dej ntws tawm ntawm lub tshuab ua haujlwm tau zoo, cov dej noo tuaj yeem hloov tau -cov khoom siv hluav taws xob yuav tsum tau muab tso rau hauv ob qho tib si pem hauv ntej thiab nram qab ntawm lub tshuab ziab khaub ncaws. Txij li cov dej dawb ua ib feem tseem ceeb ntawm cov dej noo hauv cov veneer - ua kom muaj qhov ntim loj ntawm cov pa thaum evaporation - cov vents nyob rau hauv cov seem yuav qhib dav dua. Conversely, raws li cov evaporation ntawm cov dej khi ua rau ib qho me me ntawm cov chav, cov pa tso pa tawm hauv seem tuaj yeem teem rau qhov qhib qhib.
Txhim kho cov kev taw qhia ntawm cov cua kub kub- yog li ua kom nws cuam tshuam rau cov veneers zoo ib yam thiab nrawm nrawm- yog tus yuam sij rau kev txhim kho ziab kom zoo. Muab hais tias veneers ntawm ntau hom ntoo thiab thicknesses qhia txawv qib ntawm shrinkage thaum ziab, thiab hais tias lub hom phiaj kawg ya raws cov ntsiab lus sib txawv nyob ntawm seb qhov yuav tsum tau, lub veneer pub ceev yuav tsum tau tsim kom adjustable nyob rau hauv ntau theem.
Cov khoom tseem ceeb nyob rau hauv lub tshuab ziab khaub ncaws- xws li cov khoom siv hluav taws xob thiab cov thawv plenum- kuj yuav tsum tau tsim kev tshawb fawb. Thaum tshav kub kub exchangers featuring elliptical -cov plaub fins muaj thermal efficiency thiab tau dav siv los ntawm manufacturers thoob plaws lub tshuab ziab khaub ncaws. Cov thawv plenum yuav tsum tau tsim nrog tus ntoo khaub lig sib txawv -section; tshwj xeeb, tus ntoo khaub lig- ntu ntu ntawm lub thawv yuav tsum maj mam txo los ntawm qhov chaw uas cov cua kub nkag mus. Qhov kev tsim no ua kom ntseeg tau tias qhov nrawm ntawm cov cua kub tawm ntawm txhua tus neeg lub nozzle tseem zoo ib yam thoob plaws hauv lub cev; Tsis tas li ntawd, kev siv cov flared (tswb- zoo li) nozzles pab ntxiv txhim kho cov kev taw qhia thiab kev taw qhia ntawm cov cua ntws.
