Description
Technical field
The utility model relates to a kind of Denitration in Boiler ammonium hydroxide system more particularly to a kind of circulating fluidized bed boiler denitration ammonium hydroxide
System.
Background technique
Usual steam power plant uses SNCR denitration technology, and boiler is high in high load capacity period nitrous oxides concentration, and aqua ammonia pump need to be opened
Maximum frequency, denitration efficiency is lower, while excessive ammonium hydroxide is affected to boiler plant.In underload period, flue gas is opened
After recycling, nitrogen oxides is lower.At this point, the ammonia vol that denitration of boiler smoke needs is relatively fewer, the escaping of ammonia is higher, unreacted
Ammonium hydroxide boiler plant especially air preheater and cloth bag is impacted, not only waste ammonium hydroxide, also result in equipment loss.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of circulating fluidized bed boiler denitration ammonium hydroxide system.
The technical solution adopted in the utility model:
Circulating fluidized bed boiler denitration ammonium hydroxide system, the entrance two sides of the cyclone separator of boiler are separately installed with ammonium hydroxide spray
The outlet of rifle, the cyclone separator of boiler increases an ammonia water spray gun newly, and the exit of the cyclone separator is provided with through-hole, described
Spray gun pillar is connected in through-hole, spray gun pillar outer end is equipped with ammonia water spray gun, the ammonia water spray gun and gold by flange
Belong to the connection of hose one end, the metal hose other end is connect with ammonia water pipe, is connected with cooling duct on the spray gun pillar.
Further, there are two cyclone separators, the entrance of each cyclone separator to install two ammonia for a boiler configuration
The outlet of water ammonia rifle, each cyclone separator is installed by one ammonium hydroxide ammonia rifle.
Further, the through-hole in the exit of the cyclone separator is also connected to oxygenating pipe, the front end position of spray gun pillar
In in through-hole.
Compared with prior art, the utility model has the beneficial effects that improving denitration efficiency, the escaping of ammonia is reduced, and reducing agent is used
Amount reduces, and worker operation difficulty reduces, and reduces waste, save the cost.

Specific embodiment
In order to deepen the understanding to the utility model, with reference to the accompanying drawing and specific embodiment is described in detail, this
Embodiment described in specification is only used for explaining the utility model, is not used to limit the utility model.
Shown in Fig. 1 and Fig. 2, the circulating fluidized bed boiler denitration ammonium hydroxide system of the utility model, the cyclone separator of boiler 1
23 two sides of entrance are separately installed with ammonia water spray gun 4, and the outlet 5 of the cyclone separator 2 of boiler 1 increases an ammonia water spray gun 4, rotation newly
It is provided with through-hole 6 at the outlet 5 of wind separator 2, spray gun pillar 7 is connected in through-hole 6,7 outer end of spray gun pillar is installed by flange 8
There is ammonia water spray gun 4, ammonia water spray gun 4 is connect with 9 one end of metal hose, and 9 other end of metal hose is connect with ammonia water pipe 10, spray gun shield
Cooling duct 11 is connected on pipe 7.When ammonium hydroxide is blocked in spray gun pillar 7, so that its interior environment temperature is got higher, it is necessary to cooling
Air hose 11 cools down to it.
Shown in Fig. 1, there are two cyclone separator 2, the entrances 3 of each cyclone separator 2 to install two for a configuration of boiler 1
An ammonium hydroxide ammonia rifle is installed in the outlet 5 of ammonium hydroxide ammonia rifle, cyclone separator 2, altogether six ammonia rifles.
Through-hole 6 at the outlet 5 of cyclone separator 2 is also connected to oxygenating pipe 12, and the front end of spray gun pillar 7 is located at through-hole 6
It is interior.
There are two cyclone separator, the entrance two sides of cyclone separator are separately installed with ammonia water spray gun for one boiler configuration,
It now increases two branches newly, increases an ammonia water spray gun newly in the outlet of cyclone separator, Cyclone outlet ash concentration is relatively
Low, denitration efficiency is higher.Three groups of upper, middle and lower can be divided into according to six Burners Positions after being installed.Simultaneously to the valve of six spray guns
Door aperture is adjusted, and the spray gun valve opening of the top two is 100%, and intermediate two spray gun valve openings are 75%, bottom
Two spray gun valve openings are 50%.
Boiler discharged nitrous oxides concentration is more stable at present, improves denitration efficiency, while ensure that boiler plant is transported
Capable stability.
