The utility model discloses with gas, liquid respectively by two pipe -line transportations, it is mixed alone be each nozzle with rear end gas, the liquid hybrid design of former spray gun simultaneously, because liquid outlet internal diameter and gas outlet internal diameter are all very little, set up to under 3~5 the circumstances at the nozzle, the gas outlet blowout is followed from the liquid outlet blowout is gaseous to liquid, then when the base body inner chamber mixed, the internal pressure of whole rifle remained stable basically to make every nozzle flow of spray gun unanimous, the fluid atomizing is also very even, and denitration efficiency obviously improves. The utility model provides a many shower nozzles denitration spray gun barral of a gun.
Description
Technical field
This utility model is related to gas denitrifying technology field, more particularly to a kind of denitration shower nozzle base and many shower nozzle denitrations spray
Rifle barral of a gun.
Background technology
Need when the industry such as steam power plant and garbage burning factory is produced at present using CFBB, coal-fired pot
Stove and gas fired-boiler, the flue gas of these boiler emissions will carry out denitration process.Generating fire coal pot when using less than 600MW
When stove is particularly coal-powder boiler, due to NO in boiler exhaust gasXDischarge capacity reach 400～600mg/Nm3Even more high so that SNCR
(Selective non-catalytic reduction, SNCR) is unable to reach denitration requirement, therefore can only
Using SCR (Selective Catalytic Reduction, selective catalytic reduction) techniques or SNCR+SCR joint works
Skill.
SNCR+SCR process integrations, i.e. front portion adopt SNCR, rear portion to adopt SCR.Main arrangement is in boiler flue
Bending angle part before the economizer of rear portion, installs spray gun, injection urea liquid or ammonia spirit.In such a process, no
Urea pyrolysis stove or liquid ammonia evaporator is needed, and directly urea pyrolysis, or ammonia evaporation is carried out using flue-gas temperature.Using urine
Plain solution, as far as possible position is scheduled within the temperature range of 950 ± 50, using ammonia spirit, 900 ± 50 DEG C is scheduled on as far as possible
Scope.The response time of more than 0.5 second is must assure that typically, degree of mixing must be got well.Require that droplet is atomized, sprays simultaneously
Uniformly, each capacity of sprinkler is consistent, and fog-zone farthest covers flue cross section.So that denitration efficiency reaches highest, and the escaping of ammonia
Reach minimum.
And using SCR spray guns being all the spray gun with multiple shower nozzles for lengthening at present, i.e. shower nozzle is arranged on barral of a gun, spray gun
Barral of a gun horizontal direction is lengthened, and some shower nozzles are spaced a distance along horizontal direction simultaneously；The rear-end gas-liquid of reducing agent is mixed
Close body to be atomized, be then transported at the nozzle of each shower nozzle by barral of a gun inner chamber.But due to the lengthening of spray gun barral of a gun
With increasing for shower nozzle, fluid each nozzle in the barral of a gun just has certain pressure loss, as fluid is in gun body inner chamber
Conveying, the pressure in gun body can be gradually lowered, and flow also reduces therewith, and the loss of air pressure can affect atomizing effect simultaneously, so as to
Cause the uneven of gun spraying.Thus occur less apart from the more remote flow of gas-liquid mixed body, atomizing effect is also poorer,
So that whole fog-zone is uneven, so as to affect denitration effect, denitration efficiency is reduced.

Current flue-gas denitration process includes SNCR and SCR, and the NO in boiler exhaust gasXHigher, SNCR is unable to reach de-
Nitre is required, therefore can only use SCR techniques or SNCR+SCR process integrations.SNCR+SCR process integrations, i.e. front portion adopt SNCR,
Rear portion adopts SCR.Main bending angle part of the arrangement before the economizer of boiler flue rear portion, installs spray gun, injection urine
Plain solution or ammonia spirit.It is specifically used wonderful with what SNCR played the same tune on different musical instruments.In such a process, it is not necessary to urea pyrolysis stove
Or liquid ammonia evaporator, directly urea pyrolysis, or ammonia evaporation is carried out using flue-gas temperature.Urea pyrolysis stove or liquefied ammonia steam
Send out device cost very expensive, using this technique, can both reduce investment, and catalyst only needs to, using one layer, safeguard into
This is also than relatively low.For adapting to SCR technological requirements, on the basis of the short spray gun of single injector used in former SNCR techniques, exploitation sets
The long spray gun with multiple shower nozzles is counted, i.e. shower nozzle is arranged on barral of a gun, spray gun barral of a gun horizontal direction is lengthened, and some shower nozzles are simultaneously
It is spaced a distance along horizontal direction；The spray gun has continued to use the rear end mixed structure principle of former spray gun, due to adding for spray gun
Length increases with shower nozzle, and the gas liquid mixture in barral of a gun often just has certain pressure loss through a nozzle, so spray gun
On each nozzle atomisation pressure it is unequal, the flow of each nozzle is just different, and particularly the loss of air pressure is also
The inconsistent of atomization is influenced whether, so as to cause the inhomogeneities of gun spraying, so as to reduce desulfuration efficiency.
The single tube transfer designs of former barral of a gun are that reducing agent liquid is entered from first liquid pipe, from first by this utility model
Through hole in liquid pipe sprays, and compressed air is entered from first gas pipe, and the through hole from first gas pipe sprays, in base body
Cavity in mixed aerosol for 60-80 microns fine mist, into nozzle spray.By gas, liquid respectively by two pipelines
Conveying, while the rear end air-liquid mixed design of former spray gun is individually mixed for each nozzle；Due to the through hole in the first liquid pipe
Through hole internal diameter on internal diameter and first gas pipe is all very little, and in the case where shower nozzle base is set to 3～5, liquid is from
Through hole in one liquid pipe sprays through hole of the gas from first gas pipe and sprays, and is then mixed in base body cavity
When, the pressure kept stable in whole gun body, so that each nozzle flow of spray gun is consistent, fluid atomizing is also very equal
Even, denitration efficiency is significantly improved.
