Description

A kind of gs-oil separator
Technical field
The utility model relates to a kind of gs-oil separator being arranged in refrigerating circulation, specifically a kind of gs-oil separator for compressor outlet place.
Background technology
Compressor is a kind of machine that improves gas pressure or carry gas, applies very extensive.In refrigeration industry, mining industry, Metallurgy Industry, machinery manufacturing industry, civil engineering, petrochemistry work engineering separated from the gas and national defense industry, compressor one of the key equipment that is absolutely necessary.In addition, the demand of the department such as medical treatment, weaving, food, agricultural, traffic also grows with each passing day.Compressor is called as " universal machine " because it is of many uses.Along with country is to environmental protection and energy-conservation giving more sustained attention, special gas compressor demand is increasing.
In refrigeration industry, the working medium using in traditional air-conditioning and heat pump is mainly CFCs and HCFCs, but by material impact that depletion of the ozone layer and atmosphere have been warmed, and making to find efficient, environmental protection refrigeration working medium becomes the common problem of paying close attention to of international community, natural refrigerant CO 2substitute as traditional working medium rises again.Nature environmental protection working medium CO 2because of its have nontoxic, non-combustible, cheap, be easy to get and the be safe from harm characteristic of (chamber effect potential value GWP=1, ozone depletion potential ODP=0) of environment gained great popularity.Simultaneously as air-conditioning of new generation and heat pump core component---CO 2the demand rapid growth of compressor, and to compression CO 2the quality requirement of gas further improves.How to obtain low, the clean high-quality compression CO of oil content 2gas, now with CO 2the supporting gs-oil separator of compressor just seems particularly important.
Refrigeration oil is described as compressor " blood ", can play following effect to the running of compressor: between friction pair, form a kind of diaphragm, avoid directly contacting between metal and metal, thereby alleviate frictional force effect, save energy consumption, extend the life-span of compressor, increase economic efficiency; At any time frictional heat is discharged outside machine; Anti-leak, dustproof, anti-collaborating; Anticorrosive antirust, protection friction surface is not subject to deterioration of oil or external erosion; Peace and quiet flushing, requires rubbing surface incrustation to clean eliminating etc.
Under the effect of compresser cylinder high temperature, refrigeration oil is discharged through compressor exhaust outlet with high flow rate together with vaporific form and gases at high pressure mixing also.For fear of the waste of compressor and freeze oil, affect the heat exchange efficiency of heat exchanger, improve the quality of Compressed Gas, so establish gas and oil separating plant after exhaust outlet of compressor.
Press the difference of separating mechanism, compressor adopts two kinds of oil and gas separation methods conventionally.One is called cyclonic separation method, and it is the effect that relies on oil droplet self gravitation and centrifugal force, separates the oil droplet that diameter is larger from gas.Actual test shows, is greater than the oil droplet of 1 μ m for diameter, can adopt cyclonic separation method effectively to separate.Another kind is called affine coalescent method, and the element of making by special material makes the oil droplet of diameter below 1 μ m first gather into the oil droplet that diameter is larger, and then separates.
Cyclonic separation method is that cyclone channel is set in gs-oil separator, when oil-containing gases enters after gs-oil separator, first, by cyclone channel, the oil droplet that density is greater than gas will be thrown on wall under the effect of centrifugal force, then under the effect of gravity, fall the bottom of separator.The pressure loss of cyclonic separation method is little, device structure is simple, but the oil droplet separative efficiency below 1 μ m is low for diameter.
Affine coalescent method is mainly made up of filtration and coalescent two processes.The element that this separation method adopts, is actually a kind of porous filter material, and before oil-containing gases enters filter element, diameter is greater than the oil droplet in element material aperture, and the surface at element is filtered out.Then, utilize filtering material inner flow passage shape and big or small change, can make to enter its inner minor diameter oil droplet under the effect of inertia force etc., on the fiber of material, be coalesced as major diameter oil droplet, and be filtered out.The oil droplet separative efficiency below 1 μ m is high for diameter for affine coalescent method, but is trapped in filter course in the time that the solids in Compressed Gas pass through filtering material, has caused filtering material pressure reduction (resistance) constantly to increase.Along with filtering material increases service time, in the time that filtering material pressure reduction reaches 0.08 to 0.1Mpa, filtering material must be changed, otherwise increases compressor operating cost.
Current CO 2in coolant system, directly the gs-oil separator of traditional refrigerant is borrowed often, due to CO 2characteristic and traditional refrigerant differ greatly, and CO 2refrigerant is also obviously different from the situation that mixes of its refrigeration oil and the situation of traditional refrigerant, so generally at the exhaust outlet equipment of compressor, filter core being set carries out Oil-gas Separation, there is the problems such as separative efficiency is low, crushing large, the frequent replacing of filtrate need, make systematic running cost with high, economy reduces, attended operation complexity.So design is specially for CO 2the gs-oil separator of compressor is urgently developed.
Summary of the invention
The utility model provides a kind of gs-oil separator, can overcome deficiency above-mentioned, flows by gaseous coolant collision repeatedly in oil eliminator staving, and separating for several times obviously reduces the oil content of discharging refrigerant.Especially, the utility model provides a kind of for CO 2compressor outlet place, CO under supercriticality 2separate with refrigeration oil, further object is in the less pressure loss, under the prerequisite of minimizing filter element replacing, realizes compressor CO 2gas separates with the efficient of refrigeration oil, and oil content in gas is dropped to below 1ppm.

For achieving the above object, the technical solution adopted in the utility model is: a kind of CO is provided 2compressor eddy flow gs-oil separator, this device comprises air inlet pipe, cylinder, cone, deflection plate, flowline, lubricating cup, filter core and blast pipe, be primarily characterized in that: air inlet pipe arranged tangential is on the position apart from cylinder lower end 1/3～1/2 cylinder length, and form sinuous flow for fear of air-flow in porch, air inlet pipe is goed deep into cylinder inside, the alternate arc cap shape deflection plate of having arranged two groups of conical hopper deflection plates and edge perforate in cylinder between air inlet pipe and blast pipe, be provided with blast pipe in center, cylinder upper end, be provided with filter core at blast pipe air inlet, be provided with cone in cylinder lower end, inner surface wall processing spacing in cone is reasonably rotated internal thread, be provided with lubricating cup in cone lower end, lubricating cup bottom adopts taper, being convenient to refrigeration oil refluxes.
Know-why of the present utility model is: first adopt cyclonic separation method to CO 2oil-containing gases carries out crude separation, then adopts affine coalescent method to carry out essence and separates.Cyclonic separation method is to utilize gas different with oil droplet density, distributes and presents different rules along cone radius at the different gas of centrifugal action lower density and oil droplet, separates thereby realize.CO 2the density of gas changes along with variations in temperature, and temperature more high density is less, and the density of refrigeration oil is along with the rising of temperature is substantially constant, and pressure is higher, and this rule is more obvious.Near 0 ℃, CO 2the density of gas and refrigeration oil approaches, when higher than 0 ℃, and CO 2density be less than the density of refrigeration oil, and the higher density contrast between the two of temperature is larger.Through the CO of compressor adiabatic compression 2gas temperature, pressure are all very high, very large with the density contrast of refrigeration oil.Work as CO 2when oil-containing gases enters gs-oil separator by air inlet pipe, CO 2air-flow becomes circular motion from rectilinear motion, the oil-containing CO of rotation 2air-flow is downward twist from cylinder along wall, towards cone motion, is now called outer eddy flow.Oil-containing CO 2gas produces centrifugal force in rotary course, and density is greater than to CO 2the oil droplet of gas gets rid of to wall.Because the viscosity of oil droplet is compared with large and elasticity is less, therefore once contact with wall and just lose inertia force, stick to wall surface, flow down along rotation internal thread.The outer eddy flow CO that rotation declines 2air-flow, in the time arriving cone, is drawn close because of conical contraction Er Xiang center, and its tangential velocity improves constantly.Work as CO 2when air-flow arrives a certain position, lower end of cone, continue from bottom to top from cone center the motion of spinning with same direction of rotation, form inward eddy.Inward eddy CO 2air-flow moves upward and is entered after cylinder by cone, first enter next stage deflection plate by the centre bore of conical hopper deflection plate, then enter next stage deflection plate by the edge of edge perforate arc cap shape deflection plate, by that analogy, with constantly collision and the change direction of arc cap shape deflection plate of alternate layout conical hopper deflection plate and edge perforate, because the inertia of oil droplet is greater than CO 2gas, so its movement locus and CO 2gas track difference, thus make itself and CO 2gas separates.Through cyclonic separation, wherein approximately 99.7% refrigeration oil can be separated, and because the flowing velocity between baffle means changes very soon, can be separated through the refrigeration oil of baffling approximately 99.93% repeatedly, and now unsegregated droplet diameter is many below 1 μ m.At the blast pipe entrance of gs-oil separator, be provided with porous material filter core, thereby oil content in Exhaust Gas is dropped to below 1ppm.
Because the utility model is with CO 2the pressure of Compressed Gas is as driving force, therefore without other manipulation measures, simple to operate; Employing cyclonic separation method, the separation of turning back separate with affine coalescent fado level, improve separative efficiency, improve the affine coalescent life-span, jointly realize oil gas and efficiently separate.
