Description
Technical field
The present invention relates to coal gas of steel-smelting revolving furnace to utilize technical field, is related specifically to a kind of using high-order coal gas of converter and carry
The device and its application method of high calorific value of gas.
Background technology
When pneumatic steelmaking, 1500 DEG C of high-temperature flue gas of generation, through gasifying, cooling stack is cooled to 850 DEG C -- and 1000 DEG C are laggard
Enter devaporizer.After rough dedusting, fine dedusting is carried out into electric precipitator.Traditional its work of Steam Dust now
Principle is：The operation principle of devaporizer is to send water and gas by a certain percentage in converter coal gas dry-process purifying recovery system
Into specific two-phase flow nozzle, it is injected directly into devaporizer after being atomized into fine steam-water mixing composition granule, and absorb heat
The rapid evaporation of amount, makes high-temperature flue gas cool down rapidly, converter gas is dropped to 200 DEG C or so, while flue gas from 800 DEG C -1000 DEG C
The dust of middle 20%-30% is condensed into larger particle and is deposited in ash bucket.
Authorization Notice No. CN101736116A discloses a kind of high temperature coal gas of converter discharged from converter and enters coal gas of converter
After flue, in the way of breeze blowing, make the CO in coal gas2C+CO occurs with the coal dust of addition2The endothermic reaction of=2CO, makes
Coal gas of converter temperature declines, and the mode that coal dust is added is to use nitrogen or richness CO2Exhaust gas is as injection gas to the side of breeze blowing
Formula.Can be to the rapid effective cooling of coal gas of converter progress in flue using the invention, and recycle segment converter coal gas
In CO2, while subsequent technique metallic conduit dusting can be prevented, low input, it is efficient simultaneously, reach energy-saving and environmental protection, subtract
The purpose of row has greater significance.Authorization Notice No. CN103776272A disclose be the coal gas of high temperature that is discharged from converter first
High temperature sensible heat utilization is carried out into high-temperature residual heat recovery system, via being transported to after high-temperature flue gas ceramic filter dust pelletizing system more than low temperature
Heat recovery system carries out UTILIZATION OF VESIDUAL HEAT IN.Then, coal gas of converter is sent to CO2In absorption system, CO2It is absorbed and is obtained rich in CO2
Absorbing liquid, remove CO2It is enriched with CO in coal gas of converter afterwards, can be used for hot-blast stove waste heat sky as metallurgical important energy source after collection
Gas, coke oven, station boiler and heater for rolling steel etc..The purification of both the above coal gas of converter, cooling, CO enrichments mode compared with
Good solves the problems, such as that high temperature converter coal gas high-temperature, dust are more, CO concentration is low, and still, there is also some problems, such as spray coal
Powder then needs N2Carrier gas is done, the purity for purifying rear converter coal gas is influenced, meanwhile, gas solid/liquid/gas reactions are too fierce, bring security risk,
And use CO2Liquid enrichment CO is absorbed, very big influence, while the chemical reaction heat application effect of high temperature coal gas of converter can be brought on environmental protection
Fruit will not be fine, for this purpose, the angle that we are enriched with higher than 1000 DEG C with flue gas from reaction temperature, proposes the side of built-in formed coke
Formula come carry out converter fume cooling, CO enrichment processing mode.
