Description
Technical field
The present invention relates to flue gas purifying equipment technical field, more particularly to a kind of gas cleaning absorption tower and its flue gas it is net
Change methods and applications.
Background technology
Requirement with country to environmental protection is more and more tighter, and coke oven flue gas qualified discharge standard is more and more tighter, and coke oven flue gas is net
Chemical industry skill not yet full maturity at present, each side research and design personnel by use for reference other industry smoke gas treatment technology or
Importing Foreign Advanced Technology is attempted.Activated carbon method flue gas desulfurization and denitrification technology is more ripe in steel industry application, the skill
Art can not only remove the SO in flue gas simultaneously2And NOx, also with not water consumption, non-secondary pollution, the powder effectively removed in flue gas
Dirt and heavy metal (such as mercury) pollutant, the advantages of Sulphur ressource can be reclaimed by adsorbent reactivation, Jiao can be advantageously applied to
The gold solidification of kiln gas muscle is administered.Coke oven flue gas characteristic is in addition to high nitrogen low-sulfur, also containing hydrogen sulfide, tar, heavy metal, hydro carbons etc.
Component, different coke oven constructions, different operating modes cause smoke components complicated and changeable, and the fluctuation of sulfur content excursion is big, these
The factor to be taken in during the structure design for being all coke oven flue gas absorption tower.The removing effect of active carbon flue gas desulfurizing denitration technology
Fruit is directly influenceed by inside reactor structure, therefore, improves the structure of reactor, and improve reactor is to the adaptability of flue gas
Each designer's obligation one can't decline.
The primary raw material of denitration integrated device is special-purpose activated charcoal, and it is that a kind of comprehensive strength is (pressure-resistant, wear-resisting
Damage, impact resistance), specific surface area higher than the conventional activated carbon sorbing material smaller than conventional activated carbon.Industrial application is special at present
Activated carbon is often made as cylindric.
Active carbon desulfurization technological principle is to be based on SO2SO in the absorption and catalytic action of activated carbon surface, flue gas2
At a temperature of 120 DEG C~160 DEG C, it is that sulfuric acid is adsorbed in activated carbon hole to be reacted with oxygen, water vapour in flue gas.
Physical absorption：SO2→SO2(SO2Absorption is in activated carbon micropore),
Chemisorbed：SO2+O2→SO3, SO3+nH2O→H2SO4+(n-1)H2O；
NH is sprayed during denitration3, (NH is depended on to sulfate conversion3/SO2), react and be：
H2SO4+NH3→NH4HSO4
NH4HSO4+NH3→(NH4)2SO4。
Spray ammonia and carry out denitration, activated carbon is used as removing NOxCarrier and catalyst, NOxAnd NH3About 107 DEG C of temperature~
At 167 DEG C, occurs catalytic reaction in burnt primary surface, by NOxIt is decomposed into N2And H2O, is adsorbed on activated carbon, and key reaction formula is such as
Under：
4NO+O2+4NH3→4N2+6H2O
NH4HSO4+NH3→(NH4)2SO4
Activated carbon is recycled, and adsorbs SO2Activated carbon afterwards is transported to regenerator, when being heated to 400 DEG C or so, release
Go out SO2。
The flue gas desulfurization and denitrification tower of existing more maturation can be divided into two major classes, integral type desulphurization denitration tower and two-part desulfurization
Denitrating tower, wherein, two-part desulphurization denitration tower can preferably avoid the presence of sulphur to de- in the low nitrogen gas cleaning of reply high-sulfur
Sulphur denitration has undesirable effect, therefore is preferably applied in steel sintering, pelletizing flue gas desulfurization and denitration technique, and coke oven flue gas
High nitrogen low-sulfur then more suitable for applying integral type desulphurization denitration tower, but the presence of sulphur is for direct integral type desulphurization denitration tower
Denitration ability there is larger negative effect, how quickly and conveniently to remove sulphur, improve desulfuration efficiency, improve different sulfur content
When absorption tower adaptibility to response be coke oven flue gas desulphurization denitration need solution the problem of.
