Background technology
The ammonia of a large amount of high-purities is needed to be used for nitrogen oxidation exceeded in purification flue gas in flue gases of cock oven denitrating technique
Thing, the ammonia of high-purity needs to be vaporized via liquefied ammonia, to meet the needs of flue gas denitrating technique.But currently used ammonia
The problem of vapourizing unit generally existing equipment volume is big, liquid ammonia vaporization effect difference and security is low.
The content of the invention
The utility model provides a kind of ammonia vaporizer, with equipment volume is small, in light weight, liquid ammonia vaporization effect is good and pacifies
The advantages of property is high entirely.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of ammonia vaporizer, including bobbin carriage, heat exchanging segment and the vaporization section set gradually from bottom to top；The bobbin carriage bottom is set
Drain, middle part set liquefied ammonia entrance；Heat exchanging segment is made up of tube sheet, heat exchanger tube and shell-side cylinder, heat exchanging segment and vaporization section, bobbin carriage it
Between separated respectively by upper and lower 2 tube sheets, heat exchanger tube is vertically arranged in the shell-side cylinder of heat exchanging segment, and its upper end passes through top
Tube sheet connection vaporization section, lower end through lower section tube sheet connection bobbin carriage；The bottom side of shell-side cylinder sets steam inlet, top
Opposite side sets condensation-water drain；Pars infrasegmentalis is vaporized as cone section, top sets ammonia outlet, relief valve connection and pressure tap.
The inwall of the heat exchanger tube is loose structure.
Bearing is set on the outside of shell-side cylinder in the middle part of the heat exchanging segment, for ammonia vaporizer integrally fixed support.
Compared with prior art, the beneficial effects of the utility model are：
1) heat exchanging segment of ammonia vaporizer substantially increases heat transfer temperature difference using steam as thermal source；
2) heating heat exchanger tube is carried out using water-bath mode, steam condensation latent heat can be made full use of；
3) heat transfer inside pipe wall uses loose structure, can reduce the temperature difference needed for boiling, and greatly improve boiling heat transfer system
Number；
4) vaporization section is located above heat exchanging segment, and is connected by boring section, can expand liquid ammonia vaporization space, greatly reduce gas
The overheat liquefied ammonia droplet carried secretly in phase, prevent the entrainment of liquefied ammonia droplet from causing frosting into subsequent pipeline.
Brief description of the drawings
Fig. 1 is a kind of structural representation of ammonia vaporizer described in the utility model.
Fig. 2 is heat transfer tube wall structural representation described in the utility model.
In figure：1. the vaporization section 8. of 6. condensation-water drain of bobbin carriage 2. liquefied ammonia entrance, 3. tube sheet, 4. heat exchanging segment, 5. bearing 7.
The drain of 13. steam inlet of the pressure tap 11. of 9. ammonia outlet of relief valve connection 10. cone 12. heat exchanger tube of section 14.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of ammonia vaporizer described in the utility model, including set gradually from bottom to top bobbin carriage 1, heat exchange
Section 4 and vaporization section 7；The bottom of bobbin carriage 1 sets drain 14, and middle part sets liquefied ammonia entrance 2；Heat exchanging segment 4 is by tube sheet 3, heat exchanger tube 12
Form with shell-side cylinder, separated respectively by upper and lower 2 tube sheets 3 between heat exchanging segment 4 and vaporization section 7, bobbin carriage 1, heat exchanger tube 12 is perpendicular
Directly it is arranged in the shell-side cylinder of heat exchanging segment 4, the tube sheet 3 of its upper end through top connects vaporization section 4, and lower end passes through the pipe of lower section
Plate 3 connects bobbin carriage 1；The bottom side of shell-side cylinder sets steam inlet 13, and top opposite side sets condensation-water drain 6；Under vaporization section 7
Portion is cone section 11, and top sets ammonia outlet 9, relief valve connection 8 and pressure tap 10.
As shown in Fig. 2 the inwall of the heat exchanger tube 12 is loose structure.
Bearing 5 is set on the outside of the shell-side cylinder at the middle part of heat exchanging segment 4, for ammonia vaporizer integrally fixed support.
A kind of method of work of ammonia vaporizer described in the utility model is as follows；
1) when being vaporized to liquefied ammonia, liquefied ammonia enters bobbin carriage 1 by liquefied ammonia entrance 2, afterwards into the heat exchanger tube 12 of heat exchanging segment 4
Steam condensate (SC) heat exchange outside inside, with heat exchanger tube 12；
2) steam enters heat exchanging segment 4 by the steam inlet 13 of the bottom of heat exchanging segment 4, heat exchange occurs with condensed water, and coagulate
Form condensed water, unnecessary condensed water is discharged from the condensation-water drain 6 at the top of heat exchanging segment 4；
3) the liquefied ammonia temperature that heat is absorbed after exchanging heat exceedes saturation temperature under corresponding pressure, into saturation boiling state,
Due to the loose structure of the inwall of heat exchanger tube 12, heat transfer coefficient is significantly increased, makes boiling more violent, liquid ammonia vaporization is more fast
Speed；
4) the ammonia vapour entrainment of liquefied ammonia droplet enters vaporization section 7, and liquefied ammonia droplet is again introduced into the free settling of vaporization section 7
Continue to exchange heat in heat exchanger tube 12；Ammonia then enters subsequent cell by the ammonia outlet 9 at the top of vaporization section 7.
The heat exchanger tube 12 is heated using water-bath mode.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
