A kind of safety intelligent type liquid ammonia vaporization system provided by the utility model, when work include the filling of liquefied ammonia, liquefied ammonia Vaporization, ammonia the technical process such as pressure stabilizing, accident spray, tank switching, blowdown.
One, liquefied ammonia fills
Unload the liquid phase mouth 202 of ammonia arm 1 and the liquefied ammonia import of liquid ammonia storage tank (the first liquid ammonia storage tank 3 and the second liquid ammonia storage tank 6) 36 are connected, and the gas phase mouth 201 for unloading ammonia arm 1 is connected with the gas-liquid equilibrium mouth 35 for unloading ammonia compressor 2 and liquid ammonia storage tank (3,6).
Liquid ammonia storage tank (3,6) is equipped with liquidometer 33 and acousto-optic alarm, when liquid level reaches low liquid in liquid ammonia storage tank (3,6) When the setting value of position, live sound-light alarm instrument issues alarm, reminds and supplements liquefied ammonia into liquid ammonia storage tank (3,6) in time.Unload ammonia pressure Contracting machine 2 extracts the gaseous ammonia in liquid ammonia storage tank (3,6) by gas phase pipeline and pressurizes to tank car, and the liquid ammonia in tank car passes through pressure Difference is transported to liquid ammonia storage tank (3,6) by liquid pipe.
The liquidometer 33 of liquid ammonia storage tank (3,6) with unload ammonia compressor 2 and corresponding stop valve (the first stop valve 301 and Two stop valves 302) it is provided with high liquid level warning Concatenate shut-down system, during filling ammonia, when system detection to liquid ammonia storage tank liquid When position (3,6) reaches high liquid level setting value, unloads ammonia compressor 2 and shut down, the first stop valve 301 and the second stop valve 302 are cut It is disconnected, liquefied ammonia storage in liquid ammonia storage tank (3,6).
Two, the vaporization of liquefied ammonia
During normal produce and use, liquefied ammonia exports 32 influents from the liquefied ammonia of liquid ammonia storage tank (3,6) by liquid level difference Ammonia evaporator (4,8) vaporization, the gaseous ammonia after vaporization return in storage tank from gas ammonia import 31 at the top of liquid ammonia storage tank (3,6), guarantee The stable operating pressure of whole system.
Liquid ammonia evaporator (4,8) is heated by steam, steam control valve 41, pressure sensor 304 and the second temperature It spends sensor 306 to interlock, when pressure of storage tank reaches the lower limit value of setting, steam control valve 41 is opened, at this time steam control valve 41 are controlled by second temperature sensor 306, and the aperture of steam control valve 41 is automatically adjusted according to the temperature of setting height.Work as storage Pressure tank to setting pressure when, steam control valve 41 is automatically closed, and steam control valve 41 is no longer sensed by second temperature at this time Device 306 controls.
Pressure sensor 304, the first temperature sensor 305 and spray stop valve 303 interlock.In vaporescence, if The pressure or temperature of liquid ammonia storage tank (3,6) reach the setting upper limit, and spray stop valve 303 automatically opens, starts to spray.When liquefied ammonia stores up When tank (3,6) pressure or temperature reach low level setting value, spray stop valve 303 is automatically closed, and stops spray.
Three, the pressure stabilizing of liquefied ammonia
The gaseous ammonia of liquid ammonia storage tank (3,6) internal upper part flows to ammonia through gas phase pipeline from 34 output of the gas ammonia of storage tank outlet Pressure reducing valve 71, according to using pressure requirements to depressurize ammonia, the ammonia after decompression enters 7 store buffer of ammonia surge tank, Finally point of use 72 is sent with stable pressure.
Four, accident sprays
Liquid ammonia storage tank (3,6) area is provided with multiple ammonia concentration detectors, and alarm and deluge valve 307 interlock.To avoid False alarm caused by non-ammonia leakage caused by due to other factors interference and the normal use for influencing ammonia, examine ammonia concentration It surveys instrument and hierarchical detection range is set.The detection when ammonia concentration reaches the level-one upper limit of ammonia leakage detection setting in the environment of tank field When range, deluge valve 307 is automatically opened, and accident spray port 38 sprays tank field, and other valves are unaffected in system, ammonia Normal use.When ammonia concentration reaches second level range in the environment of tank field, accident spray, tank field ammonia pipeline not only are carried out to tank field On all stop valves be automatically closed, while alarm issue alarm signal.
Five, tank switching
In the case where needing that liquid ammonia storage tank (3,6) is overhauled or leaked, need to carry out tank switching operation.When from When the first liquid ammonia storage tank 3 tank switching to the second liquid ammonia storage tank 6, third stop valve 52, the 4th stop valve 51 and the first tank switching pump 55 are opened It opens, if it is from 6 tank switching of the second liquid ammonia storage tank to the first liquid ammonia storage tank 3, then the 5th stop valve 54, the 6th stop valve 53 and second Tank switching pump 56 open, by liquefied ammonia from use tank safe transport to slack tank.
Tank switching is needed if it is because leakage occurs, due to the ammonia concentration detector and accident spray port 38 of tank field Lock, prevents ammonia from spreading.First tank switching pump 55 and the second tank switching pump 56 are the using and the reserved, and two liquefied ammonia storages can be achieved in every pump Mutual tank switching between tank (3,6).
Six, blowdown
It is equipped with ammonia in this system and absorbs slot 9, ammonia, which absorbs, is equipped with suitable water in slot 9, liquefied ammonia and ammonia in system pipeline Discharge and safety valve emptying etc. are related to the part of ammonia, eventually enter into and are only absorbed by the water in ammonia absorption slot 9.Ammonia absorbs in slot 9 Ammonium hydroxide is periodically taken away from waste liquid liquid pumping hole 17, transport to wastewater treatment point processing.
Ammonia absorb slot 9 on by steam pipework connect steam inlet 16, ammonia absorb slot 9 on third temperature sensor 92 and Steam stop valve 91 interlocks, and when water temperature is lower than setting value in ammonia absorption slot 9, automatically opens steam stop valve 91 plus steam, has Effect prevents winter ammonia from absorbing the water freezing in slot 9, and when temperature attains to a high place setting value, steam stop valve 91 is automatically closed.
Accident spray port 38 and cooling spray port 37 can all generate spent shower water when spraying, these water pass through liquid ammonia storage tank Catch pit 21 in (3,6) area finally flows into emergency pond 10, when the waste water in emergency pond 10 reaches a certain amount of or one When determining concentration, waste water in pond is delivered to by waste water treatment system 22 by waste water delivery pump 20 and is handled.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.It is all Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical Within novel protection scope.
