Description
Technical field
This utility model relates to denitration device field, is specifically related to a kind of for SCR denitration system liquid ammonia gasification mixing one
Body gasifying device.
Background technology
Along with the issue of GB13223-2011 (fossil-fuel power plant atmospheric pollutant emission standard), country is to Air Pollutant Emission
Concentration has been done before comparing and has further been limited, wherein: except the thermal power generation boiler of employing W shape flame hearth, existing circulation
Fluid bed thermal power generation boiler, and December in 2003 was constructed and put into operation before 31 days or was examined by construction project statement of the effect to be occasioned on the environment
The thermal power generation boiler discharged nitrous oxides criticized performs 200mg/m3Outward, remaining is performed both by 100mg/m3.This specification 4.4 simultaneously
The coal-burning boiler of key area is proposed 50mg/m3Discharged nitrous oxides requirement.So the announcement of new standard will be to denitration
The expansion of work produces great impetus.
Denitration mode selective catalytic reduction method (SCR) technique currently mainly.SCR denitration needs first to be passed through by liquefied ammonia
Evaporator is converted into ammonia and enters back into ammonia/air mixer mixed diluting, and liquefied ammonia needed vaporizer gasifies when
Heat is provided with high temperature medium, and uneven during gasification, noise is bigger.
Utility model content
For the problems referred to above, this utility model aim to provide a kind of can improve liquid ammonia gasification efficiency for SCR denitration
System liquid ammonia gasification conglomerate integration device.
For realizing this technical purpose, scheme of the present utility model is: a kind of for SCR denitration system liquid ammonia gasification mixing one
Body gasifying device, including gasification chamber, atomizer, air intake, steam pipe coil, described gasification chamber include leading portion mixing unit,
The gasification portion in stage casing, the blowing unit of rear, described mixing unit, blowing unit be pyramidal structure, and described gasification portion is column construction,
The front end of described mixing unit is provided with the atomizer for spraying liquefied ammonia, and described mixing unit top is provided with and enters for air
Air intake, described gasification portion outer felt, around being provided with steam pipe coil, is provided with high-temperature steam on the left of described steam pipe coil and enters
Mouthful, it is provided with steam (vapor) outlet on the right side of described steam pipe coil.
As preferably, the edge of described blowing unit and the angle of axis are 20 °～30 °.
As preferably, the edge of described mixing unit and the angle of axis are 10 °～22 °.
The beneficial effects of the utility model, by arranging gasification chamber, so that liquid ammonia gasification just completes at gasification chamber
Gasification, simultaneously as the hydrodynamics structure of gasification chamber is conducive to liquefied ammonia to mix more fully with air, ratio is in existing evaporation
The uniformity that gasifies in device is more preferable, so can be simultaneously reached at SCR reactor and catalyst preferably, fully reacts；Adopt simultaneously
There is provided heat with being wound around the steam pipe coil arranged for gasification, be prevented effectively from gasification heat absorption, and cause Gasification chamber temperature drastically
Declining, and occur material mechanical strength to reduce, heat supply is also beneficial to the efficiency of gasification.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
As it is shown in figure 1, specific embodiment described in the utility model is a kind of for the mixing of SCR denitration system liquid ammonia gasification
Integrated apparatus, including gasification chamber 3, atomizer 2, air intake 4, steam pipe coil 1, described gasification chamber 3 includes leading portion
Mixing unit 5, the gasification portion 5 in stage casing, the blowing unit 7 of rear, described mixing unit 5, blowing unit 7 are pyramidal structure, described gasification
Portion 6 is column construction, and the front end of described mixing unit 5 is provided with the atomizer 2 for spraying liquefied ammonia, described mixing unit 5 top
Be provided with for air enter air intake 4, described gasification portion 6 outer felt around being provided with steam pipe coil 1, described steam pipe coil
With mixing unit, place is provided with high-temperature steam entrance 8 on the left of in the of 1, on the right side of described steam pipe coil, in blowing unit, place is provided with steaming
Vapor outlet 9.Wherein high-temperature steam can use the high-temperature steam that boiler cooling produces.
In order to improve atomised jet effect, the edge of described blowing unit and the angle of axis are 20 °～30 °.Described mixing
The edge in portion and the angle of axis are 10 °～22 °.Bigger angle is conducive to the entrance with air, and less angle is favourable
In guiding mixed gas ejection.
By arranging gasification chamber, so that liquid ammonia gasification just completes gasification at gasification chamber, simultaneously as gasification chamber
Hydrodynamics structure is conducive to liquefied ammonia to mix more fully with air, and than gasifying in existing vaporizer, uniformity is more preferable, this
Sample can be simultaneously reached at SCR reactor and catalyst preferably, fully reacts；The steam pipe coil simultaneously using winding to arrange is
Gasification provides heat, is prevented effectively from gasification heat absorption, and causes Gasification chamber temperature drastically to decline, and material mechanical strength occurs
Reducing, heat supply is also beneficial to the efficiency of gasification.
The above, preferred embodiment the most of the present utility model, not in order to limit this utility model, every according to this
Any trickle amendment, equivalent and the improvement that above example is made by the technical spirit of utility model, should be included in this
Within the protection domain of utility model technical scheme.
