Description
Technical field
The present invention relates to a kind of oil liquid to remove water filter material.
Background technique
Oil contamination is the main factor for influencing hydraulic and lubricating system component life and operational reliability, system 70%
Above failure is all because caused by oil contamination.The pollution of oil liquid be it is various, mainly have solid particulate matter, water, air,
With electrostatic, thermal energy existing for form of energy, radiant and magnetic field etc. in microorganism, various chemical substances and system, this its
In it is maximum with the extent of injury of solid grain contamination and moisture contamination object to system.Currently, to hydraulic and lubricating system solid
Particulate pollutant filters out means comparative maturity, but in the control field of moisture contamination, due to technical difficulty, far not
Such as the research of solid dirt particulate pollutant is carried out extensive.
Common water removal mode has vacuum separation method, centrifugal separation and coarse separation method.Vacuum separation method is in the U.S., moral
Technology relative maturity in state, Japan and other countries, but China falls behind relatively in the technical research of vacuum separation；Centrifugal separation exists
Technology and application maintain the leading position in the country such as Sweden, but there has been no similar matured products for the country, China, and performance indicator is more
It is that external level is not achieved；Coarse separation method is in the states such as the U.S., Russia technology comparative maturity, but generally in light-duty fuel oil
Applications.
Hydraulic oil and lubricating oil cause using traditional centrifugal separation, coarse separation method very since viscosity is relatively high
Water content in oil is down within 200ppm content by hardly possible in a short time, and centrifugal separation cannot achieve removing for emulsification state oil liquid
Water.Although vacuum separation method can remove moisture to lower content, consuming energy, big, at high cost, occupied space is big and adds repeatedly
It is easy to accelerate oil liquid rotten after heat, the online occasion removed water and space requirement is compact can not be applied to, such as ship, aviation, electric power
Locomotive, engineering machinery etc..Therefore, traditional water removal mode consumed energy, cost, space, the limitation such as water rem oval, can not expire
Sufficient oil system cleaning equipment miniaturization, integrated, high-efficient purification new demand.
Summary of the invention
Its of the invention purpose, which is that, provides a kind of oil liquid water removal filter material, solve traditional water removal mode consumed energy,
The limitation such as cost, space, water rem oval has been unable to satisfy the miniaturization of oil system cleaning equipment, integrated, high-efficient purification is newly wanted
The problem of asking.
It adopts the technical scheme that achieve the above object, a kind of oil liquid water removal filter material, the ladder including unitary design
Degree formula filter layer and combined type remove water layer, and the gradient type filter layer is by the thick filtration material layer of glass fibre and glass fibre essence filtration material layer
It is combined, the combined type includes level-one water absorption layer, coacervate and second level water absorption layer except water layer, and level-one water absorption layer and second level are inhaled
Water layer is located at the two sides of coacervate, and the glass fibre essence filtration material layer is located at the side of level-one water absorption layer.
Beneficial effect
The present invention has the following advantages that compared with prior art.
1. being used as gradient type filter layer using the glass fiber filter layer of two layers of different pore size is compound, water removal filter material is improved
Whole filtering accuracy and contamination capacity；
2. guaranteeing emulsification state water using the compound coacervate as water removal of glass fiber filter and polyester filament spun-bonded non-woven fabrics
While dividing by demulsification with big water droplet is agglomerated into again, it is therefore prevented that fibre shedding；
3. level-one water absorption layer and second level water absorption layer using high magnification water lock fibrous filter as water removal, high-efficiency water-absorbing ability can
It ensures that water content in oil is down within 200ppm content, and maintains filter medium resistance and slowly rise, extend water removal filter material and use the longevity
Life overcomes traditional water removal techniques and consumes energy the drawback that big, at high cost, occupied space is big, water rem oval is low, is applicable to various liquid
Pressure oil and lubricating oil system meet the requirement of oil liquid high cleanliness, efficient water-removing.
Detailed description of the invention
Below in conjunction with attached drawing, the invention will be further described.
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
With reference to the accompanying drawing, the present invention is further illustrated.
A kind of oil liquid water removal filter material, gradient type filter layer 1 and combined type including unitary design remove water layer 2, such as Fig. 1 institute
Show, the gradient type filter layer 1 is combined by the thick filtration material layer 11 of glass fibre and glass fibre essence filtration material layer 12, the combination
Formula includes level-one water absorption layer 21, coacervate 22 and second level water absorption layer 23 except water layer 2, and level-one water absorption layer 21 and second level water absorption layer 23 divide
Not Wei Yu coacervate 22 two sides, the glass fibre essence filtration material layer 12 is located at the side of level-one water absorption layer 21.
The aperture of filter material of the thick filtration material layer 11 of glass fibre is 10 μm~30 μm, the filter material of glass fibre essence filtration material layer 12
Aperture is 3 μm~20 μm, is designed by the gradient type filter layer slightly to essence, and water removal filter is increased while guaranteeing filtering accuracy
Material contamination capacity, and eliminate the negative effect that solid grain contamination removes water layer water removal effect to downstream.
The glass fiber filter and polyester filament spun-bonded non-woven fabrics material that the coacervate 22 is 1 μm~2 μm by fibre diameter
Material is combined, and has the function of to be demulsified and coalesce.
The level-one water absorption layer 21 and second level water absorption layer 23 are that high magnification water lock fibrous filter material is made, and have water suction
Function.
In the present invention, the gradient type filter layer 1 is combined by the glass fiber filter layer of two kinds of different pore sizes；Combination
Formula is made of except water layer 2 three functional layers such as level-one water absorption layer 21, coacervate 22 and second level water absorption layer 23, wherein intermediate cohesion
Layer 22 has been the ultra-fine hydrophilic fibers filter material of demulsification and coalescence function, and level-one water absorption layer 21 and second level water absorption layer 23 have been water suction function
The high magnification water lock fibrous filter of energy；After level-one water absorption layer 21 filters out most free state moisture in oil liquid, emulsification state water
Divide and be then demulsified and coalesced by coacervate, be condensed into after big water droplet and depth water removal is carried out by second level water absorption layer 23 again, improves whole
Body water removal effect.
The present invention is compound as gradient type filter layer 1 by using the glass fiber filter layer of two kinds of different pore sizes, improves
The filtering accuracy and contamination capacity of filter layer eliminates the negative shadow that solid grain contamination removes water layer water removal effect to downstream
It rings；Using the compound coacervate 22 as water removal of glass fiber filter and polyester filament spun-bonded non-woven fabrics, guaranteeing emulsification state water
While dividing by demulsification with big water droplet is agglomerated into again, it is therefore prevented that fibre shedding；It is used as and is removed using high magnification water lock fibrous filter
The level-one water absorption layer 21 and second level water absorption layer 23 of water maintain filter medium resistance and slowly rise while high-efficiency water-absorbing, to prolong
Water removal filter material service life is grown.
