Description
Technical field
This utility model relates to a kind of denitrating system gas mixer, particularly relates to a kind of ammonia sky blender.
Background technology
Nitrogen oxides is the gas produced due to the oxidation of nitrogen during burning process, and it not only stimulates the breathing of people
System, damage animals and plants, damage the ozone layer, and be cause greenhouse effect, acid rain and photochemically reactive main matter it
One.Discharge to nitrogen oxides all over the world limits and requires all to tend to strict, and thermal power plant, garbage burning factory and cement plant etc.
As the main source of oxides of nitrogen gas discharge, it reduces discharging especially by attention especially.Ammonia sky blender is then denitration
A kind of equipment the most frequently used in system, but in present stage thermal power plant, the ammonia sky mixer structure of the middle use of denitrating system is excessively
Simply, ammonia sky blender fault cannot the most effectively process, and affects denitration efficiency, causes denitrating system to stop transport time serious, existing
Ammonia sky blender major part cannot meet the demand of on-the-spot actual condition.And spraying ammonia mouth is that ammonia sky blender the most easily breaks down
, often there is the situation of blocking, thus affect denitration efficiency, even cause denitrating system to stop transport in parts during use.
Utility model content
The purpose of this utility model is to provide a kind of ammonia sky blender avoiding spraying the blocking of ammonia mouth, reduces fault rate, protects
Card denitration efficiency and the operation stability of denitrating system.
The utility model discloses a kind of ammonia sky blender, including dilution airduct with for ammonia pipeline, for the outlet of ammonia pipeline
End is communicated with spray ammonia mouth, and spray ammonia mouth is positioned at dilution airduct, and described for being communicated with air line on ammonia pipeline, high pressure draught passes through
Air line injection prevents it from blocking to purging on spray ammonia mouth.
As preferably, on the tube wall of described dilution airduct, corresponding described spray ammonia mouth position is provided with manhole, the outer end of manhole
Releasable connection has manhole cover.
As preferably, it is fastened by bolts between described manhole cover and described manhole, is provided with close between manhole cover and manhole
Seal.
As preferably, described manhole cover is round plate, and its axial centre evagination has the boss being matched with described manhole internal diameter,
Described sealing ring is arranged between boss and manhole.
As preferably, the sidewall of described boss is provided with the cannelure for placing described sealing ring.
As preferably, described manhole has two, and the axial centre face about described dilution airduct is arranged symmetrically with.
As preferably, the described air line outside described dilution airduct is provided with valve.
During this utility model uses, spray ammonia mouth is purged to spray ammonia mouth by pressure-air through air line injection,
Avoid spraying ammonia mouth to block, thus ensure whole ammonia spraying amount, it is ensured that the denitration efficiency of whole denitrating system, improve denitrating system
Operation stability.
Meanwhile, in order to prevent can not avoiding spraying the blocking of ammonia mouth by pressure-air purging, at dilution airduct correspondence spray ammonia
Mouth position is provided with manhole.
In order to ensure the air-tightness of manhole, the end of manhole is provided with manhole cover, and manhole cover is provided with groove, places in groove
There is sealing ring.
For the ease of manually cleaning spray ammonia mouth, manhole is designed with two and sets about the axial centre face symmetry diluting airduct
Put.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of one preferred embodiment of this utility model.
Diagram sequence number:
1 dilution airduct, 2 confession ammonia pipelines, 3 spray ammonia mouth, 4 valves, 5 air lines, 6 manholes, 7 manholes
Lid, 8 sealing rings.
Detailed description of the invention
As it is shown in figure 1, this ammonia sky blender disclosed in the present embodiment, it includes diluting airduct 1, for ammonia pipeline 2, spray ammonia
Mouth 3, valve 4, air line 5, manhole 6 and manhole cover 7, spray ammonia mouth 3 is positioned at dilution airduct 1 with the outlet for ammonia pipeline 2 even
Logical；Air line 5 connects with for ammonia pipeline 2；Manhole 6 has two, and the axial centre face about dilution airduct 1 is symmetrical and vertically connects
Being connected to dilute on the tube wall of airduct 1 corresponding spray ammonia mouth 3 position, screw bolt and nut and manhole cover 7 phase are passed through in the outer end of manhole 6
Even, manhole cover 7 is round plate, and its axial centre evagination has the boss being matched with manhole 6 internal diameter, the sidewall of boss be provided with for
Place the cannelure of sealing ring 8.Supplying outside dilution airduct 1 is equipped with valve 6 on ammonia pipeline 2 and air line 5.
In use, high-pressure air source produces pressure-air to the present embodiment, and pressure-air is through air line injection extremely spray ammonia mouth
Spray ammonia mouth is purged, it is to avoid spray ammonia mouth blocks, thus ensures the ammonia spraying amount of whole system, it is ensured that whole denitrating system
Denitration efficiency, improve denitrating system operation stability.
Meanwhile, in order to prevent can not avoiding spraying the blocking of ammonia mouth by pressure-air purging, at dilution airduct correspondence spray ammonia
Mouth position is provided with manhole.
In order to ensure the air-tightness of manhole, the end of manhole is provided with manhole cover, and manhole cover is provided with groove, places in groove
There is sealing ring.
For the ease of manually cleaning spray ammonia mouth, manhole is designed with two and sets about the axial centre face symmetry diluting airduct
Put.
