Niaj hnub no, muaj peb yam sib npaug ntawm cov khoom siv khib nyiab combustion furnaces: (1) hom grate, (2) txoj kev thiab kev siv ntawm grate txav, (3) lub inclination lub kaum sab xis ntawm lub grate thiab cov kev taw qhia ntawm kev txav ntawm cov khib nyiab rau. grate nto, thiab lwm yam; Cov kev ntsuas peb qhov no tau dhau los, thiab cov txuj ci zoo heev los xyuas kom meej tias cov khoom pov tseg tau teeb nyob rau hauv lub sijhawm, tag nrho hlawv thiab hlawv, thiab cov grate yuav tsum tau muab faib ua peb thaj chaw: thaj chaw monotonous thiab ignition, thaj chaw combustion tseem ceeb thiab cov hmoov tshauv hlawv. cheeb tsam;
Kev lag luam khib nyiab combustion rauv tshuab tau ntsib yuav luag 130 xyoo ntawm txoj kev loj hlob, thiab kev lag luam khib nyiab combustion rauv tshuab thiab khoom siv tam sim no nce refined thiab dav siv. Cov khib nyiab incinerators Niaj hnub no, cov tshuab khib nyiab feem ntau tau muab faib ua cov pawg hauv qab no:
(1) khib nyiab txheej combustion system, xws li xaiv ntawm tumbling grate, kab rov tav reciprocating pub grate thiab inclined reciprocating grate (suav nrog rau pem hauv ntej thiab rov qab inclined reciprocating grate), thiab lwm yam. Thawj feature ntawm laminar combustion txoj kev yog tias cov khib nyiab tsis. xav tau kev kho mob hnyav. Lub tumbling grate thiab reciprocating grate muaj lub zog ignition nyhuv, uas yog comparatively haum rau combustion ntawm nroog pov tseg nrog tsawg calorific nqi thiab siab tshauv ntsiab lus.
(2) Fluidized txaj combustion system, uas yog tus yam ntxwv los ntawm tshem tawm combustion ntawm pov tseg, tag nrho kev sib cuag ntawm huab cua thiab pov tseg, thiab zoo combustion nyhuv. Txawm li cas los xij, fluidized txaj combustion yuav tsum tau roj nrog cov khoom me me thiab qhov loj me, thiab tseem yuav tsum tau noj roj tsis tu ncua, yog li nws feem ntau nyuaj rau hlawv cov khib nyiab loj, yog li lub txaj fluidized combustion system muaj qhov yuav tsum tau ua rau cov khib nyiab pretreatment, uas txwv tsis pub nws txoj kev loj hlob nyob rau hauv lub txaj. thaj tsam ntawm kev lag luam pov tseg thiab hauv nroog pov tseg combustion.
(3) Lub tshuab hluav taws xob hluav taws xob hluav taws xob hluav taws xob yog tus cwj pwm los ntawm kev muab cov khoom pov tseg rau hauv ib qho txuas ntxiv, maj mam dov lub tog raj kheej thiab hlawv kom txog thaum lub embers, yog li nws tuaj yeem ua tiav qhov kev sib cuag zoo ntawm cov khib nyiab thiab huab cua thiab cov khaub ncaws thiab tag nrho combustion. Nyob rau sab hnub poob, hom combustion furnace no feem ntau yog siv los kho cov tshuaj lom thiab cov khoom siv phom sij.
Nyob rau niaj hnub no muaj kev lag luam loj heev, kev lag luam hauv nroog cov khib nyiab combustion tshuab tau ntsib ntau yam tshiab thiab teeb meem tshiab:
1. Nyob rau hauv cov teb chaws tsim kev lag luam, qhov ntom ntom ntawm cov khib nyiab hauv nroog me me, tus nqi calorific siab, thiab cov hmoov tshauv thiab cov dej noo tsawg;
2. Cov qauv siv hluav taws xob hluav taws xob pov tseg tau dhau los ua nruj dua, tshwj xeeb tshaj yog rau kev tso tawm cov khoom phom sij hauv cov pa taws kom tswj tau zoo. Ntxiv nrog rau cov hmoov tshauv, cov khoom tsim kev puas tsuaj tseem ceeb hauv cov pa roj ntawm cov khib nyiab pov tseg yog CO, SOx, NOx, organic carbon, dioxins thiab furane. Los ntawm kev txhim kho combustion technology thiab kev hloov kho ntawm cov txheej txheem combustion, qhov tshwm sim thiab emission ntawm cov tshuaj no tuaj yeem tswj tau rau qee yam. Nyob rau hauv sib piv, nyob rau hauv lub tsib caug ntawm lub xyoo pua no, tsuas yog cov kua qaub emissions ntawm cov khib nyiab combustion furnaces thiab qis combustion kub raug txwv. Cov cua kub qis dua (piv txwv li 800 degree) yog siv los hlawv cov khoom phom sij uas ua rau muaj ntxhiab tsw hauv qhov cub;
3. Los ntawm qhov pom ntawm combustion furnace peev thiab kev lag luam kev lag luam, nws cov peev txheej qis qis yuav tsum yog 3t / h rau 20 ~ 25t / h. Yog li, niaj hnub pov tseg laminar combustion tshuab yuav tsum txaus siab rau cov lus thov hauv qab no:
(1) Cov nyhuv ignition muaj zog los xyuas kom meej qhov sib xws thiab tag nrho combustion ntawm pov tseg ntawm tag nrho cov grate nto thiab tsis txhob slagging. Lub hauv paus tseem ceeb cuam tshuam rau qhov cuam tshuam ntawm qhov hluav taws xob ntawm lub grate yog: (1) hom grate, (2) txoj kev thiab kev siv ntawm lub grate txav, (3) lub inclination lub kaum sab xis ntawm lub grate thiab cov kev taw qhia ntawm kev txav ntawm cov khib nyiab. grate nto, thiab lwm yam; txhawm rau xyuas kom lub sijhawm ignition, tag nrho combustion thiab ember ntawm cov khib nyiab, lub grate yuav tsum tau muab faib ua peb thaj chaw: monotonous thiab ignition cheeb tsam, lub ntsiab combustion cheeb tsam thiab tshauv hlawv;
(3) Cov khoom siv combustion yuav tsum muaj peev xwm hloov tau mus rau qhov tshwm sim tsis tu ncua ntawm cov khoom pov tseg (cov dej noo lossis cov nqi calorific) thiab qhov tsis sib xws. Thaum cov khoom pov tseg tsis ruaj khov, cov khoom noj khib nyiab ntawm lub qhov cub tawg, cov huab cua loj thiab nws qhov kev tawg thiab qhov kub thiab txias yuav tsum raug xa mus rau lub sijhawm;
(4) Preheating cua combustion (thaum huab cua thiab theem nrab cua);
(5) Muaj peev xwm qhia tau qee yam tshuaj ntxiv kom txo tau cov emissions ntawm tej yam teeb meem xws li dioxins, NOx thiab SOx;
(6) Tag nrho cov txheej txheem combustion yog muab faib ua lub sij hawm combustion thiab lub sij hawm combustion ntawm combustible teeb meem tshuaj nyob rau hauv lub flue gas, thiab cov huab cua uas yuav tsum tau txaus siab los ntawm kev kub hnyiab ntawm cov embers ntawm flue gas nyob rau hauv lub sij hawm kawg. . Thaum lub sij hawm pov tseg combustion lub sij hawm, tus nqi ntawm combustion huab cua yuav tsum tau tswj kom tsis txhob muaj kev kub ntxhov ntawm lub cub tawg kub thiab cov tshauv ntau dhau.
(7) Ua kom cov pa roj carbon tsawg ntawm cov hmoov tshauv thiab ya tshauv (1 ~ 3%), thiab zoo heev combustion.
