Description
Technical field
The utility model relates to a kind of gs-oil separator.
Background technology
In fuel injection helical lobe compressor, in Compressed Gas, a large amount of oil is injected into the between cog volume of compressor.The gas mixture that these oil and compressed gas form, after the identical compression process of experience, is discharged in the gs-oil separator of unit.Gs-oil separator is one of capital equipment in fuel injection helical lobe compressor machine set system.In order to reduce the oil content in unit exhaust and to recycle the lubricating oil in unit, must utilize gs-oil separator that lubricating oil is separated effectively from gas.
Press the difference of separating mechanism, in fuel injection helical lobe compressor unit, adopt two kinds of different oil and gas separation methods.Be called a Mechanical Method, i.e. impaction or cyclonic separation method, it is the effect that relies on oil droplet self gravitation and centrifugal force, the larger oil droplet of separated diameter from gas.Actual test shows, is greater than the oil droplet of 1 μ m for diameter, all can adopt Mechanical Method effectively to be separated.Another kind is 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.In fuel injection helical lobe compressor unit, generally all adopt this two kinds of different oil and gas separation methods now simultaneously, use Mechanical Method as crude separation, and separated as essence by affine coalescent method.
Early stage Mechanical Method generally adopts impaction, certain barrier is set on the flow direction of gas mixture, and after gas mixture and barrier collision, the oil droplet in mixture will be gathered in the surface of barrier, and under the effect of gravity, fall the bottom of separator.While adopting impaction, the speed of gas mixture strikes obstacles has certain scope, and its optimum value is relevant with the density of gas and lubricating oil.In general, best stroke speed is 3m/s left and right.
In modern unit, general cyclonic separation method or the two kinds of methods of adopting are in conjunction with carrying out crude separation.This method is that cyclone channel is set in gs-oil separator, and when gas mixture enters after gs-oil separator, first, by cyclone channel, large oil droplet will be thrown on wall under the effect of centrifugal force, then, under the effect of gravity, falls the bottom of separator.
When gas mixture is undertaken after separation by Mechanical Method, wherein approximately 99.7% oil can be separated, and droplet diameter is now many below 1 μ m, and unrenewable Mechanical Method is carried out separation.
Affine coalescent method is the oil droplet below 1 μ m mainly for separating of diameter, filtration and coalescent two processes, consists of.The element that this separation method adopts (oily fine separator), is actually a kind of porous filter material, and before gas mixture 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.At present, oily fine separator generally adopts the materials such as ultra-fine fibre glass of the special exploitation of purposes for this reason, has obtained the effect that deoiling effect is good, the life-span is long, pressure drop is little.The oily fine separator that specialized factory produces can make the oil content in gas drop to 1～2ppm.
Because thereby gs-oil separator is to coordinate by a plurality of structures the effect that reaches Oil-gas Separation, its performance quality has a significant impact the oil consumption of compressor, effect and exhaust quality.The structural design of gs-oil separator directly affects the separating effect of gas mixture, is also related to the use cost of air compressor, so it is optimized to adjustment, is necessary.The problem that existing gs-oil separator need to solve is to go out different oil-gas separator structures according to different cylindrical shell size design, and improves the efficiency of crude separation.
