Abstract
The utility model discloses a helical blade type ammonia water evaporator of low resistance, including evaporimeter casing, screw -tupe spoiler, twin -fluid atomization spray gun, the screw -tupe spoiler is fixed in in the evaporimeter casing, the evaporimeter casing is equipped with hot -blast import and mixed gas outlet, hot -blast import is located the head end of evaporimeter casing, mixed gas outlet is located the end of evaporimeter casing, the twin -fluid atomization spray gun inserts in the evaporimeter casing, the hot -blast importer of the bottom of twin -fluid atomization spray gun spout orientation to, the spout is central at same height with the screw -tupe spoiler. The utility model discloses the next potential safety hazard of the high follow -up equipment belt of giving of local ammonia concentration has effectively been avoided. Through the eddy current effect behind the screw -tupe spoiler, reinforceed hot -blast turbulent effect, improved hot -blastly and the heat transfer effect aqueous ammonia, reduced hot -blast quantity, reduced the hot air system resistance, shortened the route of aqueous ammonia evaporation, reduced the structural length of ammonia water evaporator casing, the utility model discloses simple structure, it is with low costs.
Description
Technical field
This utility model is related to a kind of spiral vane types ammonia vaporizer of lower resistance.
Background technology
The SCR denitration technique of Pump for Medium and Small Power Generating Set often uses ammonia as reducing agent, by introducing boiler hot air, ammonia is steamed
Send out carries out denitration reaction for ammonia into Benitration reactor.Ammonia vaporising device need to realize two functions：By ammonia evaporating completely
It is sufficiently mixed with hot blast with the ammonia after ensureing to evaporate.
Existing ammonia vaporizer, generally using increase vaporizer diameter, reduces hot air flow to meet above-mentioned 2 points requirement
Speed, reaches the effect of ammonia evaporating completely so as to extend ammonia with hot blast time of contact.For ensure evaporation after ammonia with
Hot blast is sufficiently mixed, and generally using vaporizer length is extended, outlet arranges flap mode to ensure mixing.Therefore conventional ammonia steams
It is typically all that profile is huge to send out device, and length 2m or so, hot-air system resistance is larger, and resistance is 1000～1200Pa, is both unfavorable for
Site layout project, also increases hot-air system fan pressure head, so as to increase operating cost.
Utility model content
The purpose of this utility model is to overcome not enough in existing product, there is provided a kind of spiral vane types ammonia of lower resistance steams
Send out device.
In order to achieve the above object, this utility model is achieved through the following technical solutions：
A kind of spiral vane types ammonia vaporizer of lower resistance, including evaporator shell, screw type spoiler, two-fluid mist
Change spray gun, the screw type spoiler is fixed in evaporator shell body, and the evaporator shell is provided with hot wind inlet and gaseous mixture
Body is exported, and the hot wind inlet is located at the head end of evaporator shell, and the mixed gas outlet is located at the end of evaporator shell,
The twin spray gun is inserted in evaporator shell body, and the bottom of the twin spray gun is provided with spout, the spray
, towards the hot wind inlet direction of evaporator shell, the spout is with screw type spoiler center in sustained height for mouth.
Screw type spoiler described in the utility model be located at evaporator shell hot wind inlet and twin spray gun it
Between.
Screw type spoiler described in the utility model is three helical blades.
The beneficial effects of the utility model are as follows：This utility model is common with evaporator shell by screw type spoiler
Effect, makes the ammonia concentration of vaporizer end mixed gas outlet uniform, effectively prevent local ammonia concentration high to subsequently setting
The standby potential safety hazard brought.Eddy current effect after screw type spoiler, enhances the turbulent flow effect of hot blast, improves hot blast
With the heat transfer effect of ammonia, hot blast consumption is reduced, reduce hot-air system resistance, shorten the path of ammonia evaporation, reduced
The structure length of ammonia evaporator shell；This utility model simple structure, low cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of screw type spoiler.
Specific embodiment
The technical solution of the utility model is described further with reference to Figure of description：
As shown in figure 1, including evaporator shell 1, screw type spoiler 2, twin spray gun 3, the screw type is disturbed
Stream plate 2 is fixed in evaporator shell 1, and the evaporator shell 1 is provided with hot wind inlet 11 and mixed gas outlet 12, the heat
Wind inlet 11 is located at the head end of evaporator shell 1, and the mixed gas outlet 12 is located at the end of evaporator shell 1, described double
Fluid atomizing spray gun 3 is inserted in evaporator shell 1, and the bottom of the twin spray gun 3 is provided with spout 31, the spout
31 towards evaporator shell 1 the direction of hot wind inlet 11, the spout 31 and the center of screw type spoiler 2 are in sustained height.
The screw type spoiler 2 is located between the hot wind inlet 11 of evaporator shell 1 and twin spray gun 3.
As shown in Fig. 2 the screw type spoiler 2 is three helical blades.
This utility model makes vaporizer end mixed gas by screw type spoiler and the collective effect of evaporator shell
The ammonia concentration of outlet is uniform, effectively prevent the potential safety hazard that local ammonia concentration height brings to follow-up equipment.By spiral
Eddy current effect after type spoiler, enhances the turbulent flow effect of hot blast, improves the heat transfer effect of hot blast and ammonia, reduces heat
Wind consumption, reduces hot-air system resistance, shortens the path of ammonia evaporation, and the structure for reducing ammonia evaporator shell is long
Degree；This utility model simple structure, low cost.
It should be noted that listed above is only a kind of specific embodiment of the present utility model.Obviously, this utility model
Above example is not limited to, there can also be many deformations.
In a word, the institute that one of ordinary skill in the art can directly derive from this utility model disclosure or associate
There is deformation, be considered as protection domain of the present utility model.
