The clamping sleeve is arranged on the outer wall of the oil collector, and the cooling capacity caused by ammonia evaporation is used for cooling liquid ammonia in a refrigeration system, so that a heat exchange coefficient of the outer wall of the oil collector is increased, the ammonia evaporation speed of the oil collector is increased, and the cooling capacity caused by the ammonia evaporation is fully recycled and used; therefore, two effects are achieved; the novel ammonia refrigeration oil collector has the characteristics of simple structure and high practicability.

Description

Novel ammonia refrigeration oil catcher
Technical field
The present invention relates in a kind of ammonia refrigerating installation the oil catcher for separating of ammonia and lubricating oil.。
Background technology
Ammonia has good thermodynamic property, in relatively large refrigeration system, is all generally to adopt ammonia as cold-producing medium.In compression, condensation, throttling, evaporation four steps of ammonia refrigeration circulate, compression is wherein one of four step circulations, the general consumed power of compressor of ammonia refrigerating installation is all very large, sucks the low-pressure saturated steam of flash-pot by power consumption, through overcompression, exports overheated high temperature, gases at high pressure.
The compressor of ammonia refrigerating installation need to have good lubrication by oil circulation system, but because air-flow rolling action, compressor lubricant oil can be taken to each place of whole ammonia refrigeration system by ammonia steam, due to lubricating oil with ammonia does not dissolve each other and density is slightly larger than liquefied ammonia, thereby lubricating oil can be deposited on each device bottom in whole refrigeration system.So have corresponding pipeline and valve to coordinate oil catcher to carry out concentrating of ammonia and lubricating oil in refrigeration system, in oil catcher, carry out the separation of ammonia, oil, ammonia under low pressure evaporates and enters low-pressure system, and the straight lubrication oil after ammonia separation is got back to compressor.
The about 2.5MPa of the general design pressure of oil catcher in existing ammonia refrigerating installation is typical pressure vessel.After ammonia refrigeration periodic duty a period of time, just the lubricating oil of device bottom deposition need be concentrated on to oil catcher and carry out ammonia, oil separation, the lubricating oil of realizing compressor refluxes.But in operating process owing to there is no thermal source, the evaporation of ammonia low pressure is very slow, again due to a large amount of heat absorptions of ammonia low pressure evaporation, even if oil catcher is when operate summer, outer wall all can be met cold junction ice because of moisture in air and be reached tens cm thicks, forms similar heat-insulation layer, make ammonia evaporation separation slower, at this moment need trickle ice, in oil catcher, the cold effect of ammonia evaporation also be it's a pity and is not used, and has caused the loss of a large amount of colds.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, a kind of novel ammonia refrigeration oil catcher is provided, this oil catcher is by arranging chuck, the cold of ammonia evaporation is lowered the temperature for the liquefied ammonia of refrigeration system, both strengthened the coefficient of heat transfer of oil catcher outer wall, accelerated the speed of ammonia evaporation in oil catcher, fully reclaim again and utilized the cold of ammonia evaporation, kill two birds with one stone, there is feature simple in structure, practical.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of novel ammonia refrigeration oil catcher, comprise withstand voltage oil catcher tank body, tank body is provided with ammonia oil mixture and enters control valve, connects low-pressure control valve, oil return valve and bottom valve, it is characterized in that: the outer wall of oil catcher tank body is provided with chuck, chuck is provided with ammoniacal liquor discharge control valve and ammoniacal liquor entrance control valve.
Described oil catcher tank body is provided with liquid level gauge, is convenient to observe the liquid level in tank body.
Described oil catcher tank body is provided with Pressure gauge, and the pressure of being convenient to monitor in tank body changes.
Described chuck is provided with heat-insulation layer, prevents that cold runs off.
When oil catcher carries out the purifying of ammonia evaporation and lubricating oil, first the ammonia oil mixture of each device bottom deposition is entered in oil catcher tank body by control valve, the ammoniacal liquor entrance control valve of chuck is controlled the liquefied ammonia from buffering storage ammonia tank, ammoniacal liquor discharge control valve is controlled the expansion valve of connecting devaporation device, chuck is set to the passage of ammonia circulation liquefied ammonia here, closing ammonia oil mixture enters control valve and opens and connect low-pressure control valve and just can connect low-pressure system, ammonia in ammonia oil mixture will be vaporized, and by connecting low-pressure control valve, enters low-pressure system.
Liquefied ammonia in chuck provides thermal source for the ammoniacal liquor vaporization in oil catcher tank body, and ammonia evaporation in oil catcher tank body is also for entering the liquefied ammonia cooling of chuck, is conducive to liquefied ammonia and enters evaporator evaporation and can absorb more heat.When oil catcher tank body upper temp is no longer obviously lower, illustrate that the ammonia in oil catcher evaporates, remaining is exactly straight lubrication oil, can control oil return valve and make lubricating oil get back to compressor.
Compared with prior art, beneficial effect of the present invention is: structural design is ingenious, simple, rationally utilizes heat exchange, by chuck is set, the cold of ammonia evaporation in oil catcher tank body is lowered the temperature for liquefied ammonia, and in oil catcher, the cold effect of the separated evaporation of ammonia is fully used; The speed of oil catcher ammonia and lubricating oil separation and efficiency also significantly improve; Equipment is simple and reliable, and convenient operation is practical.
Accompanying drawing explanation
Fig. 1 is the planar structure schematic diagram of novel ammonia refrigeration oil catcher.
In figure, each label represents:
1, ammonia oil mixture enters control valve; 2, connect low-pressure control valve; 3, Pressure gauge; 4, oil catcher tank body; 5, ammoniacal liquor discharge control valve; 6, chuck; 7, liquid level gauge; 8, ammoniacal liquor entrance control valve; 9, oil return valve; 10, bottom valve.
The specific embodiment
Now by reference to the accompanying drawings, the present invention is further illustrated.
Novel ammonia refrigeration oil catcher as shown in Figure 1, comprise withstand voltage oil catcher tank body 4, tank body is provided with ammonia oil mixture and enters control valve 1, connects low-pressure control valve 2, oil return valve 9 and bottom valve 10, the outer wall of oil catcher tank body is provided with chuck 6, and chuck is provided with ammoniacal liquor discharge control valve 5 and ammoniacal liquor entrance control valve 8.
