Description
Technical field
The utility model relates in a kind of ammonia refrigerating installation, before ammonia steam enters compressor from evaporimeter, for the separator of gas-liquid separation.
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 refrigeration circulate, compression is wherein one of four step circulations, the general consumed power of ammonia compressor is all very large, by power consumption, suck the low-pressure saturated steam of flash-pot, through overcompression, export overheated high temperature, gases at high pressure, what enter ammonia compressor must be saturated ammonia steam, if the ammonia steam sucking carries liquid phase, not only can cause the raising of ammonia compressor power consumption, also can damage compressor, therefore, must guarantee that the saturated ammonia steam that enters compressor can not carry liquid phase.
Due to the incompressible or very difficult compression of liquid ammonia, if entering compressor, liquid ammonia can cause away " damp car ", there is serious cylinder knock in compressor, especially easily damages compressor, thereby what will guarantee to enter compressor is the saturated ammonia steam that does not carry liquid phase.
Therefore, before saturated ammonia steam enters compressor, from evaporimeter ammonia steam out, all first pass through gas-liquid separator, separation is liquid ammonia wherein, but existing gas-liquid separator separates effect is limited, can not remove the liquefied ammonia that saturated ammonia steam carries completely, treatment effect is far from reaching people's desired value.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art exactly, a kind of novel ammonia refrigeration gas-liquid separator is provided, this gas-liquid separator by the liquefied ammonia that saturated ammonia steam is carried repeatedly turn back, separation, removed comparatively thoroughly the liquefied ammonia carrying in saturated ammonia steam, eliminated to greatest extent the impact of liquefied ammonia on compressor, operating efficiency and the service behaviour of compressor have been improved, saved electric power, extended the service life of compressor, there is feature simple in structure, practical.
For overcoming the deficiencies in the prior art, the utility model is taked following technical scheme:
A kind of novel ammonia refrigeration gas-liquid separator, comprise gas-liquid separator tank body, it is characterized in that: from evaporator tube in wireway gos deep into gas-liquid separator tank body and the mouth of pipe be provided with out air sifter cage, on wireway outer wall, be welded with blade with angle, gapped between blade with angle, on blade with angle, be welded with the urceolus of tubulose; In gas-liquid separator tank body, be provided with division board and flow-stopping plate; Division board separates tank body, and ammonia steam can only be risen on the gap between blade with angle; Flow-stopping plate blocks ammonia steam, makes ammonia steam increase by baffling; Division board is provided with the fluid flow tube under shed; Gas-liquid separator tank body top is provided with blast pipe and removes compressor.
Described gas-liquid separator tank body is provided with liquid level gauge, is convenient to observe and regulation and control liquid level.
Because temperature in gas-liquid separator tank body is very low, in order to isolate heat transfer, at gas-liquid separator tank wall, be provided with heat-insulation layer, prevent that cold runs off.
During work, liquefied ammonia in gas-liquid separator tank body is kept to suitable liquid level, from evaporator tube, through wireway, pass under liquid level and connect and sieve cage, carry out the low-pressure gas of flash-pot, by the diffusion of sieve cage, evenly discharge and contact with liquefied ammonia, realize ammonia vapo(u)rous and overflow liquid level, sieve cage has certain distance every bottom, avoids the lubricating oil of disturbance bottom deposition.
Tubulose urceolus, a part for blade with angle and wireway outer wall forms cyclone, saturated ammonia steam is in uphill process, be subject to stopping of division board, can only enter division board upper strata by swirler blades gap, be subject to flow-stopping plate barrier effect and produce baffling, for guaranteeing gas-liquid separation effect, can repeat upper strata swirl vane and baffle plate baffling through same structure.
When ammoniacal liquor face overflows steam, be isolated plate isolation, can only flow by impeller clearance, high-speed gas is forced eddy flow by blade, and wherein ammoniacal liquor, in swirling eddy uphill process, is centrifuged and spreads out, and departs from gas phase, realizes gas-liquid separation for the first time.
When swirling eddy is blocked by flow-stopping plate, can only walk around by baffling, produce inertia for the second time and stream, turn, realize gas-liquid separation for the second time.
Saturated ammonia steam continues to rise, and can repeatedly repeat the workflow of front twice gas-liquid separation, and the liquefied ammonia of separating is got back in the liquid phase of tank body lower part by fluid flow tube, realizes the complete separation of liquefied ammonia in saturated ammonia steam, finally by blast pipe, enters compressor.
The utility model, by saturated ammonia steam repeatedly eddy flow, baffle plate baffling in uphill process, forms and repeatedly forces gas liquid separating function series connection, has very strong gas-liquid separating function.Add knockout drum body section larger, the air-flow rate of climb is slower, also have the drop natural subsidence under Action of Gravity Field, thereby gas-liquid separation is very thorough.
Compared with prior art, the beneficial effects of the utility model are also:
Structural design is ingenious especially, rationally utilizes gas-liquid directly to contact, and realizes the rapid saturation of ammonia steam; Multistage separatory series connection guarantees thorough separated liquid phase; Airflow passes resistance is very little; Simple and the automatical and efficient operation of device structure, has eliminated the impact of liquefied ammonia on compressor to greatest extent, has improved operating efficiency and the service behaviour of compressor, has saved electric power, has extended the service life of compressor, has feature simple in structure, practical.
