Hauv cov ntsiab lus ntawm kev tshem tawm plua plav, "lub hnab lim plua plav" tsis yog cov tshuaj lom neeg tshwj xeeb, tab sis cov ntsiab lus dav dav rau tag nrho cov khoom siv cuam tshuam los ntawm lub hnab lim plua plav hauv lub hnab. Thaum cov plua plav-laden airflow dhau los ntawm lub hnab lim cylindrical ua los ntawm polyester, PPS, iav fiber ntau los yog aramid fiber ntawm lub lim cua ceev ntawm 0.5-2.0 m / min, cov plua plav tau khaws cia rau ntawm phab ntsa ntawm lub hnab thiab hauv qhov pores vim muaj ntau yam kev sib tsoo xws li inertial kev sib tsoo, kev tshuaj xyuas, thiab electrostatic adsorption. Thaum lub sij hawm, ib txheej ntawm lub hnab lim plua plav nrog "hmoov ncuav mog qab zib" raws li cov tub ntxhais yog tsim.
Cov yam ntxwv ntawmhnab lim plua plavtsim los ntawm kev lag luam sib txawv sib txawv heev: ya tshauv los ntawm cov thee hluav taws xob boilers yog grey thiab kheej kheej, nrog ib tug particle loj ntawm 1-50 µm, muaj SiO₂ thiab Al₂O₃; cement kiln plua plav yog alkaline thiab yooj yim rau nqus noo noo thiab agglomerate; hlau oxide hmoov hauv kev lag luam metallurgical yog ib qho nyuaj thiab angular; thiab cov plua plav ntes tau hauv cov chaw muag tshuaj thiab zaub mov yuav yog cov tshuaj nquag lossis cov hmoov txhuv nplej siab. Lub resistivity, noo noo cov ntsiab lus, thiab flammability ntawm cov plua plav no yuav thim rov qab txiav txim siab xaiv cov hnab lim - tiv thaiv zoo li qub, txheej, roj-pov thawj thiab tsis muaj dej tsis zoo lossis kub-kub resistant nto kho, tag nrho cov no yog ua kom cov plua plav lim hnab "tau txais" cov plua plav no ntau dua thiab nyab xeeb.
Dust Filter Bag lub hom phiaj: tsis yog "filtering" xwb
Kev ua raws li Emission: Feem ntau lub teb chaws hauv ntiaj teb tau sau PM10, PM2.5 lossis tag nrho cov plua plav concentration txwv rau hauv cov cai. Lub hnab ntim plua plav zoo tsim tuaj yeem txo cov plua plav nkag ntawm 10–50 g / Nm³ rau ≤10 mg / Nm³, kom ntseeg tau tias lub chimney tsis tawm "daj zaj".
Tiv thaiv cov khoom siv hauv qab: teeb tsa lub hnab lim ua ntej pneumatic conveying, roj turbines lossis SCR denitrification systems tuaj yeem zam plua plav hnav, thaiv cov txheej txheem catalyst, thiab txuas ntxiv lub neej ntawm cov khoom kim.
Cov khoom siv rov qab: Hauv cov txheej txheem xws li cov hlau zoo nkauj, tsis tshua muaj lub ntiaj teb polishing hmoov, thiab lithium roj teeb zoo electrode cov ntaub ntawv, lub hnab lim plua plav nws tus kheej yog cov khoom muaj txiaj ntsig zoo. Cov plua plav yog stripped los ntawm qhov chaw ntawm lub hnab lim los ntawm pulse spraying lossis mechanical vibration, thiab rov qab mus rau cov txheej txheem ntau lawm los ntawm cov hmoov tshauv hopper thiab ntsia hlau conveyor, realizing "plua plav rau plua plav, kub mus rau kub".
Kev tswj hwm kev noj qab haus huv: Yog tias cov plua plav concentration hauv qhov chaw ua haujlwm siab tshaj 1-3 mg / m³, cov neeg ua haujlwm yuav raug mob pneumoconiosis yog tias raug rau lub sijhawm ntev. Lub Hnab Filter Hnab ntim cov plua plav hauv cov yeeb nkab kaw thiab lub hnab ntim khoom, muab qhov pom tsis tau "plua plav thaiv" rau cov neeg ua haujlwm.
Kev txuag hluav taws xob thiab kev ua kom zoo dua qub: Qhov saum npoo ntawm lub hnab lim niaj hnub yog npog nrog PTFE membrane, uas tuaj yeem tswj tau cov huab cua permeability siab ntawm qhov sib txawv ntawm qhov qis (800-1200 Pa), thiab lub zog siv ntawm cov kiv cua yog txo los ntawm 10% -30%; Nyob rau tib lub sijhawm, qhov ruaj khov siab sib txawv teeb liab tuaj yeem txuas nrog cov kiv cua sib txawv thiab cov ntse plua plav ntxuav kom ua tiav "kev tshem tawm plua plav ntawm kev thov".
Los ntawm "ash" mus rau "khoom muaj nqis": txoj hmoo ntawm lub hnab lim plua plav
Kev ntes tsuas yog thawj kauj ruam xwb, thiab kev kho mob tom ntej txiav txim siab nws txoj hmoo kawg. Cement nroj tsuag sib tov cov hmoov av rov qab rau hauv cov ntaub ntawv raw; thermal fais fab nroj tsuag muag ya tshauv rau cov pob zeb sib xyaw cov nroj tsuag ua cov ntxhia pob zeb; tsawg hlau smelters xa bagged plua plav enriched nrog indium thiab germanium rau hydrometallurgical rhiav. Nws tuaj yeem hais tau tias Lub Hnab Plua Plav tsis yog tsuas yog fiber ntau thaiv, tab sis kuj yog "peev txheej txheej txheem".
Lub hnab lim plua plav yog cov "exiled" hais nyob rau hauv cov txheej txheem kev lag luam, thiab lub hnab lim plua plav yog "gatekeeper" uas muab lawv lub neej thib ob. Los ntawm cov qauv zoo nkauj fiber ntau, nto engineering thiab ntse tu, lub hnab lim tsis tsuas yog tiv thaiv lub ntuj xiav thiab huab cua dawb xwb, tab sis kuj tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm thiab cov txiaj ntsig ntawm cov tuam txhab. Thaum cov plua plav condenses mus rau hauv cov hmoov tshauv sab nraum lub hnab phab ntsa thiab rov qab los ua cov khoom siv hauv cov hmoov tshauv hopper, peb nkag siab tiag tiag lub ntsiab lus ntawm lub hnab lim plua plav: nws tsis yog tsuas yog lub lim lim, tab sis kuj yog qhov pib ntawm kev lag luam ncig.
