Abstract
The invention relates to the technical field of waste gas treatment and particluarly relates to a novel denitration nozzle base, a multinozzle denitration spray gun barrel and a denitration spray gun. According to the denitration spray gun, a reduction agent liquid enters into the denitration spray gun through a reduction agent inlet, flows along the inner wall of a liquid pipe and is sprayed out through a through hole in the liquid pipe; compressed air enters into a first sleeve through a compressed air inlet, is sprayed out through air inlets formed in the bottom ends of the nozzle bases, is mixed and atomized into 40-80mu m fine fogdrops in cavities of the nozzle bases, and then enters into the nozzles so as to be sprayed out. Since the inner diameter of the through hole in the liquid pipe and the inner diameter of the air inlet are quite small; under a condition that 3-5 nozzle bases are arranged, the liquid is sprayed out through the through hole in the liquid pipe, gas is sprayed through the air inlets formed in the bottom ends of the nozzle bases and then is mixed in the cavities of the nozzle bases, so that the pressure in a whole gun body is basically kept stable, the flow of each nozzle of the spray gun is consistent, flow atomization is quite uniform, and the denitration efficiency is obviously improved.
Description
Technical field

Nitre spray gun barral of a gun and denitration spray gun.
Background technology
The industry such as steam power plant and garbage burning factory needs using CFBB, coal-burning boiler when being produced at present
And gas fired-boiler, the flue gas of these boiler emissions will carry out denitration process.Using generating coal-burning boiler during less than 600mw
Particularly coal-powder boiler when, due to no in boiler exhaust gasxDischarge capacity reach 400～600mg/nm3Even more high is 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) technique or sncr+scr joint work
Skill.
Sncr+scr process integration, that is, front portion adopt sncr, rear portion adopts 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

Scope.
Current flue-gas denitration process includes sncr and scr, and the no in boiler exhaust gasxHigher, sncr is unable to reach de-
Nitre requires, and therefore can only use scr technique or sncr+scr process integration.Sncr+scr process integration, that is, front portion adopt sncr,
Rear portion adopts scr: main bending angle part before the economizer of boiler flue rear portion for the arrangement, installs spray gun, injection urine
Plain solution or ammonia spirit.In such a process it is not necessary to urea pyrolysis stove or liquid ammonia evaporator, directly utilize flue gas temperature
Degree carries out urea pyrolysis, or ammonia evaporation.Urea pyrolysis stove or liquid ammonia evaporator cost are very expensive, using this work
Skill, both can reduce investment, and catalyst only needs to using one layer, and maintenance cost is also than relatively low.For adapting to scr technological requirement,
On the basis of the short spray gun of single injector used in former sncr technique, exploitation devises the long spray gun with multiple shower nozzles, that is, spray
Head is arranged on barral of a gun, and spray gun barral of a gun horizontal direction lengthens, and some shower nozzles are spaced a distance along horizontal direction simultaneously；Should
The rear end mixed structure principle of former spray gun continued to use by spray gun, and due to the lengthening of spray gun and increasing of shower nozzle, the gas-liquid in barral of a gun is mixed
Zoarium often just has certain pressure loss through a nozzle, so the atomisation pressure of each nozzle on spray gun not phase
Just different Deng the flow of, each nozzle, the loss of particularly air pressure also affects the inconsistent of atomization, thus causing to spray
The inhomogeneities of gun spraying, thus reduce desulfuration efficiency.
The single tube transfer designs of former barral of a gun are that reducing agent liquid enters from reducing agent entrance 5-1, along liquid by the present invention
The inwall flowing of pipe 3 ejection of the through hole 3-1 from liquid line 3, compressed air enters first sleeve from compressed air inlet 5-2
6, spray from the air inlet 4 of nozzle base 1 bottom setting, in the cavity of nozzle base 1, mixed aerosol is 40～80 μm thin
Little droplet, enters back into nozzle 2 and sprays；Gas, liquid are separately conveyed by the present invention, are designed as the gas-liquid mixed of former spray gun simultaneously
Each nozzle individually mixes；Because the through hole internal diameter of the through hole 3-1 internal diameter on liquid line 3 and air inlet 4 is all very little, in spray
In the case that gonys seat 1 is set to 3～5, through hole 3-1 from liquid line 3 for the liquid sprays, and gas is from nozzle base 1 bottom
The air inlet 4 of setting sprays, and when then being mixed in the cavity of nozzle base 1, the pressure in whole gun body keeps substantially
Stable, so that each nozzle flow of spray gun is consistent, fluid atomizing is also very uniform, and denitration efficiency significantly improves.
In order that those skilled in the art more fully understands the present invention program, below in conjunction with the accompanying drawings and embodiment is to this
Bright it is described in further detail.
