Reducing agent mixing arrangement.
Background technique
The main stream approach of thermoelectricity generating set gas denitrifying technology is that selective catalytic reduction reaction (SCR) and selectivity are non-
Catalytic reduction reaction (SNCR).SCR technology is more widely applied since denitration efficiency is higher, and principle is at 300-400 DEG C
Temperature range in, reducing agent (ammonia) is injected in flue and is sufficiently mixed with flue gas, the Benitration reactor in downstream is carried out, is being urged
The nitrogen oxides (NOX) in flue gas is removed under the catalytic action of agent, generates nitrogen and water.
Due to comparing exhaust gas volumn, the amount of injection of reducing agent is smaller, while the section of flue is larger, therefore flue gas difficult to realize
It is sufficiently mixed with reducing agent, causes the entrance flow field uniformity of Benitration reactor and catalyst poor, influence denitration effect.Especially
It is the Practical Project high for denitration efficiency, reducing agent mixes with flue gas the removing effect that effect directly affects nitrogen oxides
Fruit.
Existing reducing agent mixing arrangement generallys use grid etc. and divides cloth apparatus, since its spout bore is smaller, in flue gas
