Description
Technical field
The present invention relates to a kind of moving granular bed filters.
Background technique
The production method of the smelting furnaces such as converter be it is intermittent, i.e., smelting furnace is emptied, again before and after smelting production
The warming-up exercises such as new charging.
During warming-up exercise, there is no the smelting for having intensity, for smoke components based on air, flue-gas temperature is air heats
It is slightly improved after radiation, there is no the flue dust for having intensity.
During smelting production, with the raising of rate of driving, by the flue-gas temperature of fire door evolution up to 1600 DEG C, flue gas at
CO content may be up to 90% in point, and the dust that flue gas carries is up to 150g/Nm3, the complicated component of dust, mainly have FeO,
Fe2O3, CaO etc., the reaction such as oxidation heat liberation will also occur in subsequent flue for the flue gas and flue dust of evolution.
It smelts production duration to be usually no more than 20 minutes, warming-up exercise duration is generally also no more than 20 minutes.Due to
It is big to need very strong reply for the production method of this fast intermittent formula, the facility of converter gas treatment facility especially high temperature
Warm area cooling thermal impact, the ability of the impact of big concentration dust, explosion hazard gases aggregation.
At present both at home and abroad in prior art, the highest production method of energy recovery utilization efficiency is: sealed vapour is arranged
Change cooling stack, water vapour, setting spray or vaporation-type are transferred to the obvious heat of smoke that radiating heat form is 800 DEG C of chief commander or more
Direct cooling tower by flue-gas temperature be reduced to 70 DEG C or 250 DEG C hereinafter, recycle and utilizing CO content height and O2The low converter of content
Coal gas.800 DEG C of obvious heat of smoke below are not able to achieve Exposure degree due to smoke components are explosive, smoke content is high etc..
The direct cooling tower of fountain by flue-gas temperature be reduced to 70 DEG C hereinafter, can will portion big absolutely while cooled flue gas
Point flue dust washes down, but there are the problem of: sensible heat is unrecovered, water consume is big, sewage needs to handle.The direct cooling tower of vaporation-type is by cigarette
Temperature degree is reduced to 250 DEG C hereinafter, can separate part bulky grain flue dust while cooled flue gas, but existing asks
Topic: sensible heat is unrecovered, the steam consumption is big.To meet the needs of 800 DEG C of obvious heat of smoke below recycling, converter gas need to be subjected to high temperature
Dedusting.
Domestic and international relatively good high-temperature dust removal technology has at present:
Metallic fiber chimney filter, metal sintering web filter etc. can satisfy the requirement of high-temperature dust removal, but expensive.
Rigid surface filter of ceramic filter, too cotton etc. also can satisfy the requirement of high-temperature dust removal, but have frangible, afraid of water
The problems such as, and it is expensive.
Cyclone dust collectors (including multi-tube dust cleaner etc.) are the high-temperature dust removal technologies of comparative maturity, are widely used in fluidizing
Industrial circles are waited in bed boiler, but are difficult to trap 5 μm of particles below, it is impossible to be used in atmosphere emission control.
Granular-bed filter (including rake granular-bed filter, cyclone type granular-bed filter, moving-bed type stratum granulosum mistake
Filter etc.), have many advantages, such as that resistant to high temperatures, shock resistance, filtrate are from a wealth of sources, but the research experience without being used for batch production,
Also it is not applied to the research experience of explosion hazard gases, and is difficult to trap fine particle, it is impossible to be used in atmosphere emission control.
Summary of the invention
