Description
Technical field
The utility model is related to a kind of uphole steam generator, more particularly to a kind of desulphurization denitration uphole steam generator.
Background technology
Fuel oil movable steam injection boiler is the key equipment in crude oil production practice, the characteristics of with following several respects：
1）Fuel oil steam injection boiler, which has, to have a very wide distribution, dissipates feature, and the equipment control managerial skills of different regions differ；2）Fuel oil steam injection
Boiler is frequently necessary to movement, therefore equipment volume itself is relatively small, compact, is easy to movement；3）Fuel oil steam injection boiler is positioned over
Field, and it is often mobile, therefore do not possess perfect sewage disposal system；
And the boiler exhaust gas desulphurization denitration state of the art is：
1）Denitration technology present situation
Selective catalytic reduction（SCR）
This method is by using NH3And catalyst, in the temperature of suitable reaction（330~400℃）, NOx is reduced to N2。
Reaction has selectivity, NH3Only with NOx react, substantially not with O2Reaction, so referred to as selective-catalytic-reduction denitrified.SCR
Denitrating technique system can be divided into liquefied ammonia storing and transporting system, ammonia prepare and supply system, ammonia/air mixing systems, ammonia spraying system,
SCR reactor assemblies and waste water absorb processing system etc..SCR denitrations are fixed denitration outside stove, and system footprint is big；Reaction temperature
Degree is relatively low；Catalyst is easily poisoned；Polymolecularity dust can covering catalyst surface, make its activity reduction；Unreacted NH3And cigarette
SO in gas2Effect, generates (NH that is perishable and blocking4)2SO4、(NH4)2SO3, while reducing NH3Utilization rate；Investment and fortune
Row is costly.
SNCR method (SNCR)
In 950 ~ 1050 DEG C of this narrow ranges, without catalyst, only and in flue gas NO reacts ammonia, and oxygen of typically getting along well
Reaction, this method is also known as selective non-catalytic agent absorption（SNCR）Method.Typical SNCR process systems are by reduction storage tank, many
The layer composition such as reducing agent jetting device and matched control instrument.SNCR system denitrating flue gas processes are by following four
Individual basic process is completed：Receive, store, prepare reducing agent；The metering output of reducing agent and water mixed diluting；It is suitable in boiler
Reducing agent after the injection dilution of position；Reducing agent mixes progress denitration reaction with flue gas.SNCR denitration technique denitration efficiency is not high；
NH3/ NOx is high, and the escape amount of ammonia is larger, (the NH of generation4)2SO4、(NH4)2SO3It can block or corrode air preheater；Reactant
And vehicle medium（Air）Consumption it is big；Ammonia reduction NO only has positive effect at 950 ~ 1050 DEG C, and temperature window is narrow.
2）The desulfurization state of the art
Alkali desulphurization
By allocating certain density alkali lye（NaOH）, alkali lye is delivered in desulfurizing tower using lye pump, by efficient
Atomizer is atomized the liquid into and the SO in flue gas2Reaction, reaches the purpose of desulfurization.Alkali method desulfurizing technology system is prepared by alkali lye
System, desulfurizing tower, desulfurization fluid circulation, Waste Water Treatment composition.Alkali desulphurization system footprint is big, and equipment fixation can not be moved
It is dynamic；There is sewage generation.
