Cov kav dej rwb thaiv tsev

Cov yeeb nkab rwb thaiv tsev yog ib lub raj xa dej uas muaj rwb thaiv tsev kub. Nws lub luag haujlwm tseem ceeb yog txo qhov poob cua sov thaum thauj cov khoom siv (xws li dej kub, pa dej, thiab roj kub) hauv cov yeeb nkab thaum tiv thaiv cov yeeb nkab los ntawm kev cuam tshuam ntawm ib puag ncig. Nws yog siv dav hauv kev tsim cua sov, kev tsim cua sov hauv cheeb tsam, petrochemicals, kev tsim kho hauv nroog, thiab lwm yam.

1. Cov Qauv Tseem Ceeb

Cov yeeb nkab rwb thaiv tsev feem ntau yog cov qauv sib xyaw ua ke ntau txheej uas muaj peb yam tseem ceeb:

• Cov Yeeb Nkab Hlau Ua Haujlwm: Lub txheej sab hauv, uas yog lub luag haujlwm rau kev thauj cov xov xwm. Cov ntaub ntawv feem ntau suav nrog cov hlau tsis muaj qhov sib txuas, cov hlau galvanized, lossis cov yeeb nkab yas, thiab yuav tsum tiv taus qhov siab thiab tiv taus xeb.

• Txheej rwb thaiv tsev: Txheej nruab nrab tseem ceeb, uas yog lub luag haujlwm rau kev rwb thaiv tsev kub. Cov ntaub ntawv siv feem ntau suav nrog polyurethane ua npuas ncauj, pob zeb wool, iav wool, thiab polyethylene. Polyurethane ua npuas ncauj yog qhov kev xaiv tseem ceeb tam sim no vim nws cov thermal conductivity tsawg thiab kev ua haujlwm rwb thaiv tsev zoo heev.

• Lub Tsho Sab Nraud: Cov txheej tiv thaiv sab nraud tiv thaiv cov txheej rwb thaiv tsev los ntawm cov dej noo, kev laus, thiab kev puas tsuaj ntawm lub tshuab. Cov ntaub ntawv feem ntau suav nrog cov polyethylene siab (HDPE), fiberglass, lossis cov txheej tiv thaiv xeb.

II. Cov Hom Tseem Ceeb thiab Cov Yam Ntxwv

Raws li cov khoom siv rwb thaiv tsev thiab daim ntawv thov, cov hom thiab cov yam ntxwv feem ntau yog raws li nram no:

• Cov Yeeb Nkab Polyurethane Uas Muaj Cov Khoom Siv Rwb Thaiv Kub: Kev ua tau zoo ntawm cov cua sov ≤ 0.024 W/(m·K), kev ua haujlwm rwb thaiv kub zoo, tiv taus qhov kub tsawg, thiab tiv taus kev laus. Haum rau cov kav dej kub thiab cov kav dej pa uas muaj qhov kub ntawm -50°C thiab 120°C, nws yog qhov kev xaiv zoo tshaj plaws rau cov cua sov hauv nruab nrab thiab cov tshuab cua sov hauv pem teb.

• Cov Yeeb Nkab Rockwool Insulated: Tiv taus kub heev (txog li 600°C) thiab muaj qib hluav taws kub (Chav A tsis kub hnyiab), tab sis nws nqus dej tau zoo, nws xav tau kev tiv thaiv dej noo. Nws feem ntau yog siv rau cov yeeb nkab kub hauv kev lag luam (xws li cov yeeb nkab boiler).

• Cov Yeeb Nkab Iav Uas Muaj Cov ...

III. Cov Txiaj Ntsig Tseem Ceeb

1. Kev Txuag Hluav Taws Xob thiab Kev Txo Kev Siv Hluav Taws Xob: Txo qhov poob cua sov hauv nruab nrab, txo kev siv hluav taws xob hauv kev cua sov, kev tsim khoom hauv kev lag luam, thiab lwm yam xwm txheej. Kev siv mus sij hawm ntev tuaj yeem txo cov nqi khiav lag luam tau zoo heev.

2. Kev Tiv Thaiv Cov Kav Dej: Lub plhaub sab nraud tiv thaiv dej, av xeb, thiab kev cuam tshuam ntawm lub cev, ua rau cov kav dej siv tau ntev dua thiab txo qhov zaus kho.

3. Kev Ua Haujlwm Ruaj Khoov ntawm Cov Kav Dej: Tswj qhov kub nruab nrab kom ruaj khov kom tiv thaiv kev hloov pauv ntawm qhov kub thiab txias los ntawm kev cuam tshuam rau kev ua haujlwm (piv txwv li, tswj qhov kub thiab txias sab hauv tsev rau cov kav dej cua sov thiab xyuas kom meej tias cov txheej txheem ruaj khov rau cov kav dej kev lag luam).

4. Kev Teeb Tsa Yooj Yim: Qee cov kav dej rwb thaiv tsev yog prefabricated, tsuas yog xav tau kev sib txuas thiab kev teeb tsa ntawm qhov chaw, ua rau lub sijhawm tsim kho luv dua thiab txo qhov nyuaj.

IV. Cov Ntawv Thov Siv Tau

• Hauv nroog: Cov kav dej cua sov hauv nroog thiab cov kav dej kais (kom tiv thaiv kev khov thaum lub caij ntuj no).

• Kev Tsim Kho: Cov kav dej cua sov hauv pem teb hauv cov tsev nyob thiab cov tsev lag luam, thiab cov kav dej cua sov thiab cua txias rau cov cua txias hauv nruab nrab.

• Kev Lag Luam: Cov kav dej roj kub hauv kev lag luam roj av thiab tshuaj lom neeg, cov kav dej ncu hauv cov chaw tsim hluav taws xob, thiab cov kav dej cryogenic nruab nrab hauv kev thauj khoom txias.
