PP Spray Tower

Lub PP tsuag ntauwd yog cov pa roj- cov khoom siv tshuaj tiv thaiv cov khoom siv khib nyiab uas tsim los ntawm kev vuam thiab sib sau ua ke polypropylene (PP) daim hlau. Nws muaj cov khoom tseem ceeb xws li lub cev ntauwd, cov tshuaj tsuag, cov txheej txheem ntim khoom, txheej demisting, circulating dej tank, cua duct, thiab kiv cua.
Leveraging cov kua qaub thiab alkali corrosion kuj zoo heev ntawm cov khoom siv polypropylene, cov cuab yeej ua tiav cov kua qaub / alkaline pov tseg cov pa roj, plua plav, thiab qis -concentration organic pov tseg roj los ntawm kev sib cuag ntawm cov tshuaj txau thiab cov pa khib nyiab. Dav siv nyob rau hauv nruab nrab thiab qis-concentration pov tseg roj kev kho mob scenarios xws li electroplating, electronics, chemical engineering, txheej, thiab tshuaj, nws nta tus nqi qis, lub teeb yuag, yooj yim installation, thiab yooj yim txij nkawm, ua hauj lwm raws li ib tug kev lag luam ib puag ncig tiv thaiv khoom rau me me thiab nruab nrab- cov lag luam loj kom tau raws li cov qauv pov tseg roj pov tseg.

Lub hauv paus ntsiab lus tseem ceeb ntawm kev lim dej khib nyiab los ntawm PP cov tshuaj tsuag ntauwd yog cov pa roj- cov kua dej sib txuas ua ke nrog cov tshuaj tiv thaiv lub cev / tshuaj sib xyaw ua ke. Tag nrho cov txheej txheem kev kho mob tau muab faib ua peb theem tseem ceeb, zoo ib yam ntawm FRP cov tshuaj tsuag tshuaj, tab sis nrog cov khoom siv adaptability ntau inclined rau nruab nrab thiab qis -concentration, tsis muaj zog corrosion ua hauj lwm tej yam kev mob:
1.Pretreatment thiab Flow Equalization theem
Plua plav lossis corrosive khib nyiab nkag mus rau hauv pej thuam los ntawm huab cua inlet hauv qab, yog uniformly faib los ntawm cov roj faib phaj, thiab tom qab ntawd ntws mus rau sab saud, ua ntej kev sib cuag nrog cov atomized absorbent ntog los ntawm cov tshuaj tsuag rau saum lub pej thuam. Cov plua plav hauv cov pa khib nyiab yog ntes los ntawm cov tee dej thiab poob rau hauv cov dej ntws hauv qab nrog cov tee dej; lub caij no, cov evaporation ntawm lub absorbent absorbs tshav kub, txo qhov kub ntawm cov pa khib nyiab kom tsis txhob siab - kub puas tsuaj rau PP ntauwd lub cev.

2.Core Purification Reaction Theem
Cov roj khib nyiab pretreated nkag mus rau hauv cov txheej ntim (xws li PP hollow balls, multi-faceted hollow balls, los yog garland packing), uas ua rau kom cov roj ntau ntxiv -kua thaj chaw. Lub absorbent tsim ib hom kua zaj duab xis nyob rau saum npoo ntawm lub ntim, ua tag nrho kev sib cuag nrog cov countercurrently ntws cov pa khib nyiab thiab nyob rau hauv lub hom phiaj purification tshwm sim:
➤ Acidic waste gas (HCl, H₂SO₄ pos huab, NOₓ): Ua rau muaj kev cuam tshuam tsis zoo nrog cov alkaline absorbents (NaOH, Ca(OH)₂ daws) los tsim cov ntsev soluble;
➤ Alkaline khib nyiab (NH₃): Ua rau muaj kev cuam tshuam tsis zoo nrog cov kua qaub absorbent (dilute sulfuric acid, dilute hydrochloric acid) kom tshem tawm ammonia;
➤ Tsawg-concentration organic pov tseg roj (VOCs): Muaj kev sib cais lossis oxidative decomposition cov tshuaj tiv thaiv nrog cov khoom siv tshwj xeeb (xws li cov kuab tshuaj organic, cov tshuaj oxidative) kom txo cov concentration ntawm cov organic teeb meem.

3.Demisting thiab Discharge Stage
Cov roj purified pov tseg tseem ntws mus rau hauv cov txheej txheem demisting (PP baffle demister, xaim mesh demister) kom tshem tawm cov tee dej uas nkag mus rau hauv cov pa khib nyiab thiab tiv thaiv cov pa phem thib ob. Thaum kawg, qhov nce ntawm - mus rau - tus qauv huv huv yog tawm tawm sab nraum zoov los ntawm qhov chaw nres nkoj tso rau saum lub pej thuam los ntawm tus kiv cua.
Lub circulating dej tank nyob rau hauv qab sau cov absorbent tom qab cov tshuaj tiv thaiv, uas yuav recycled tom qab sedimentation thiab pom. Cov kua dej tshiab tsis tu ncua ntxiv thiab cov kua khib nyiab hloov pauv.

PP tshuaj tsuag yees tuaj yeem muab faib ua ntau yam raws li cov qauv tsim, cov yam ntxwv ua haujlwm, thiab kev kho cov nplai. Lub ntsiab parameter thiab nta yog raws li nram no:
Kev faib tawm los ntawm Cov Qauv Txheej Txheem
1.Vertical Countercurrent PP Spray Tower Lub ntauwd lub cev siv cov qauv ntsug cylindrical. Cov pa roj pov tseg nkag los hauv qab thiab tawm los ntawm sab saum toj ntawm tus pej thuam, thaum lub tshuab nqus dej yog txau los ntawm sab saum toj thiab refluxes mus rau hauv qab, ua kom muaj roj-kua sib cuag. Nws boasts lub sij hawm sib cuag ntev, siab purification efficiency, thiab ib tug tsis kam ntawm 800-1200Pa, ua rau nws haum rau nruab nrab thiab tsawg-concentration pov tseg roj kev kho mob thiab lub mainstream industrial hom.

2. Kab rov tav PP Txau Ntauwd Lub ntauwd lub cev nta cov kab rov tav kab rov tav, qhov twg cov pa khib nyiab thiab nqus tau nyob rau hauv cross- ntws sib cuag. Nrog rau cov qauv compact thiab me me hauv pem teb, nws muaj feem xyuam rau me me ntawm - qhov chaw cov pa roj pov tseg hauv kev cob qhia (xws li cov chaw soj nstuam thiab lub tank me me electroplating). Nws qhov tsis zoo yog tias kev ua kom huv huv yog me ntsis qis dua li cov yees ntsug.

Ntim Ntauwd / Tsis yog -Packed Ntauwd
(1) Packed PP Spray Tower: Nruab nrog ib qho ua tau - nyob rau hauv PP cov khoom ntim txheej, nws muaj cov pa roj loj -kua thaj chaw tiv tauj thiab kev ua kom huv huv ntawm ntau dua lossis sib npaug li 85%, haum rau cov pa khib nyiab nrog cov khoom sib txuas;
(2) Tsis yog -Packed PP Txau Ntauwd:

(2) Multi-Stage PP Spray Tower: Configured nrog 2-3 txheej ntawm cov tshuaj tsuag, sib txawv absorbents yuav muab ntxiv rau txhua txheej, ua rau nws haum rau tov- cov roj khib nyiab (xws li kua qaub-alkali sib xyaw cov pa roj).
(3) Integrated Spray-Adsorption PP Tower: Integrated spray purification and a activated carbon adsorption layer. Lub hauv ntej kawg tshem tawm cov kua qaub, alkali, thiab plua plav, thaum lub tsheb kawg adsorbs residual organic pov tseg gas, ua rau nws tsim nyog rau tsawg -concentration VOCs khib nyiab roj hauv txheej thiab luam ntawv industries.

Kev faib tawm los ntawm Kev Kho Ncua
1.Small-Sized PP Spray Tower: Ntauwd txoj kab uas hla yog li ntawm 0.5 txog 1.0m, nrog rau huab cua ntim ntawm 500-3000m³/h, haum rau cov khoom siv hluav taws xob hauv cov chaw sim thiab cov chaw ua haujlwm me me.
2.Medium-Sized PP Spray Ntauwd: Ntauwd txoj kab uas hla yog 1.0-2.0m, nrog rau huab cua ntim ntawm 3000-20000m³ / h, muaj feem xyuam rau tag nrho cov khib nyiab pov tseg hauv kev cob qhia me me thiab nruab nrab.
3.Large-Sized PP Spray Tower: Ntauwd txoj kab uas hla spans 2.0-3.0m, nrog rau huab cua ntim ntawm 20000-50000m³ / h, haum rau centralized pov tseg roj kev kho nyob rau hauv loj ntau lawm rhiav.

Cov Ntsiab Lus Xaiv

Cov huab cua ntim yuav tsum raug xaiv raws li 1.2-1.5 npaug ntawm cov pa roj pov tseg tiag tiag kom khaws cov npoo;

If the dust content of the waste gas is >80mg / m³, lub tshuab nqus plua plav plua plav lossis lub hnab lim yuav tsum tau nruab rau pem hauv ntej kom tsis txhob txhaws qhov ntim;

PP tshuaj tsuag yees tsis pom zoo rau siab -cov pa roj carbon monoxide pov tseg ib leeg, thiab yuav tsum tau ua ke nrog cov pa roj carbon adsorption lossis cov khoom siv catalytic combustion;

Qhov kub tsis kam ntawm PP cov khoom yog tsawg dua lossis sib npaug li 80 degree, yog li yuav tsum muaj lub tshuab ua ntej - cua txias rau siab - cov pa khib nyiab kub.

Nrog rau cov yam ntxwv ntawm kev ua haujlwm siab thiab cov kua qaub-alkali corrosion kuj, PP tshuaj tsuag yees tau siv dav hauv nruab nrab thiab qis-cov khoom siv khib nyiab pov tseg. Cov xwm txheej tseem ceeb yog raws li nram no:

1. Cov yam ntxwv ntawm cov khoom tseem ceeb

2. Kev siv tau zoo

(1) Pov tseg Gas Purification nyhuvRau nruab nrab thiab qis -concentration acid-alkali khib nyiab roj, qhov ua kom huv huv yog ntau dua lossis sib npaug li 90%, thiab qhov hluav taws xob qhov hluav taws xob tuaj yeem ruaj khov qis dua li lub teb chaws tus qauv kev txwv; Kev tshem tawm tus nqi ntawm cov xim pos huab thiab plua plav yog ntau dua lossis sib npaug li 95%, txo qis cov pa tsw phem.

(2) Cov khoom siv ua haujlwm zooKev pabcuam lub neej ntawm lub cev ntauwd tuaj yeem ncav cuag 8-10 xyoo. Cov kiv cua txhawb nqa muaj kev siv hluav taws xob tsawg, lub kaw lus ua haujlwm nrog kev ua haujlwm tsis zoo, thiab ua haujlwm ruaj khov yam tsis muaj qhov yuam kev rau lub sijhawm ntev.

(3) Kev Tswj Tus NqiTus nqi ntawm cov khoom siv thiab kev ua haujlwm thiab kev saib xyuas tus nqi qis dua li ntawm FRP thiab stainless hlau tshuaj tsuag yees, pab me thiab nruab nrab- cov lag luam loj ua tiav - rau - cov qauv siv hluav taws xob pov tseg nrog kev nqis peev tsawg.

(4) Kev Txhim Kho Ib puag ncigUa haujlwm zoo tshem tawm cov roj corrosive thiab plua plav los ntawm kev cob qhia cov pa roj pov tseg, txo qhov corrosion ntawm cov pa khib nyiab ntawm cov khoom siv thiab kev noj qab haus huv rau cov neeg ua haujlwm, thiab txhim kho ecological ib puag ncig ntawm lub Hoobkas thiab thaj chaw ib puag ncig.
