Ammonia refrigeration operation principle：After liquid ammonia absorbs the heat of cooled object in evaporator 50, it is low to be vaporized into low pressure
The ammonia of temperature, is sucked by refrigeration compressor 60, is discharged into condenser 70 after being compressed into the ammonia of high pressure-temperature, the quilt in condenser 70
Cooling water temperature exothermic condensation is high pressure ammoniacal liquor, and the ammoniacal liquor through the throttling of throttle valve 20 for low-temp low-pressure is again introduced into evaporator 50
Endothermic gasification achievees the purpose that circularly cooling.
Specifically, in the above-described embodiment, the density of the liquefied ammonia in low pressure recycle bucket 30 is less than the density of oil, liquefied ammonia with
After oil layer, by the effect of gravity, the oil discharge outlet 36 of oil from 30 lower section of low pressure recycle bucket is flowed into oil removing pot 81, is then opened
6th shut-off valve 813 discharges oil, when oil is when low temperature viscosity is big or since sediment and oil mix blocking row
When hydraulic fluid port 36, the 7th shut-off valve 816 is opened, at this moment the liquefied ammonia after ammonia pump pressurizes enters oil removing from back blow port 814
Tank 81 drives the oil of poor fluidity to be discharged from the oil-drain pipe 812 of oil removing pot 81, into the liquefied ammonia of the elevated pressures of oil removing pot 81
Reversely enter low pressure recycle bucket 30 from oil discharge outlet 36 so that blocked oil discharge outlet is dredged, while blowback such as oil removing pot 81
Liquefied ammonia density less than oil density, since the effect of buoyancy enters 30 Returning utilization of low pressure recycle bucket from oil discharge outlet 36 again.
Oily fast transfer after layering can be gone out low pressure recycle bucket 30 by the oil removing pot 81 of the utility model setting, be avoided
Oil enters the problem of causing liquid nitrogen pump upper liquid difficult after ammonia pump 40；When occurring, oil extraction is difficult or the feelings blocked occurs in oil discharge outlet 36
Condition forces oil removing pot 81 using ammonia pump 40 to be exported to the blowback pipeline 815 that is connected with the back blow port of oil removing pot 81 814
Oil extraction and the pressure dredging of oil discharge outlet 36 to blocking；So as to both solve oil equipment system is influenced into system downstream component
Cold performance, and solve oil extraction and do not cause equipment fault freely.

8th shut-off valve 92 on bypass duct 91 is installed, the sight glass 93 connected with oil packet 90 is additionally provided at the top of oil packet 90, to see
Examine oil level in oil packet 90.
In general, after the throttling of high pressure ammoniacal liquor, a kind of two-phase mixture being made of flash gas, liquefied ammonia and oily particle is generated
Oily movement is penetrated, the liquid phase part in bucket is made to generate eddy motion, so that liquefied ammonia cannot be layered quickly with oily particle, and it is direct
It is squeezed into evaporator 50 by ammonia pump, makes the heat exchange efficiency of evaporator 50 reduce, cause energy dissipation；Sight glass is used in the present embodiment
93 and oil packet 90 combination, effect of draining the oil is good, is more advantageous to entire cooling cycle system, but also will be discharged from low pressure recycle bucket 30
Liquefied ammonia recycling with oil packet 90 in, return again to high pressure ammonia storage tank 10 and recycle；Specifically application method is：By 90 installation of oil packet
On the position identical with 40 basis of ammonia pump, dynamic pressure area and the distance in static pressure area in low pressure recycle bucket 30 can be increased in this way,
Simultaneously because the proportion difference of liquefied ammonia and oil causes oily particle to be deposited in oil packet 90, and liquefied ammonia is risen in cycle low pressure bucket, oil
It is layered whereby with liquefied ammonia；By observing sight glass 93, accurately oil can be released, so as to ensure that the heat exchange of evaporator 50
Efficiency.
Module or unit in the utility model embodiment device can be merged, divide and be deleted according to actual needs
Subtract.
