Description
Technical field
The utility model belongs to fume treatment technical field, specifically a kind of equipment for denitrifying flue gas.
Background technology
Chemism research shows: when good mixing, and the reaction of reducing agent and NOx substantially reached balanced reaction denitration rate and is greater than 90% in 0.3 second.Therefore, for practical application, mixing of reducing agent and flue gas is the core of SNCR technology.It is good that reducing agent mixes with flue gas, and just fully, system denitration rate is just high for chemical reaction, and it is just few that unreacted reducing agent leaks into the secondary pollution caused in air; Otherwise the difference that reducing agent mixes with flue gas, chemical reaction is just insufficient, and the denitration rate of system is just low, and it is just large that unreacted reducing agent leaks into the secondary pollution caused in air.
Utility model content
The purpose of this utility model is to solve deficiency of the prior art, provides a kind of equipment for denitrifying flue gas.
The utility model comprises tank used for storing ammonia, dilution water tank, mixing weighing module, atomizing steam air inlet pipe, dried compressed air inlet pipe and ammonia spray nozzle; Ammonia spray nozzle comprises pipe and nozzle outer tube in nozzle; The inlet communication of ammonium hydroxide delivery pump, dilution water conveying delivery side of pump and mixing weighing module, pipe in the outlet nozzle of mixing weighing module.
Preferably, in described nozzle, pipe is communicated with atomizing steam air inlet pipe; The compressed air control valve of cavity between nozzle outer tube with pipe in nozzle is communicated with dried compressed air inlet pipe.
Preferably, described dilution water delivery pump is arranged on the bottom of dilution water tank.
Preferably, described ammonia spray nozzle extend into the top of burner hearth, is provided with burner in burner hearth.
The utility model has the following advantages: mixed with ammoniacal liquor weak solution by atomizing steam, accomplish ammonia atomization, improves the mixed effect of ammoniacal liquor weak solution and flue gas, and improve denitrating flue gas efficiency, denitration efficiency can reach more than 50%; Nozzle arrangements is reasonable, and penetration performance is good, and reducing agent mixes with flue gas, passes into dry compressed air, can prevent spray nozzle clogging in nozzle between pipe, nozzle outer tube.In addition, the utility model is practical, and production cost is not high, and this product is adapted at promoting the use of in like product.
