Abstract
The utility model belongs to a compound insulating oil accurate dehydration filter core for filtering water in insulating oil in the technical field of physical separation. The compound insulating oil accurate dehydration filter core comprises a filter core shell, a demulsification coalescence layer, a dehydration layer and a water diversion filter screen; the dehydration layer is installed in the middle of the filter core shell, the demulsification coalescence layer is installed at the inlet end of the filter core shell, and the water diversion filter screen is installed at the outlet end of the filter core shell. The utility model adopts a method of modified glassfiber demulsification coalescence layer compound kapok fiber wrapping high molecular water-absorbing resins or filling granularhigh molecular water-absorbing resins, and can efficiently filter out water in free state, emulsified state and dissolved state in the insulating oil by utilizing the demulsification coalescence function of the modified glassfiber demulsification coalescence layer and strong hydrophilic absorption capacity of the high molecular water-absorbing resins.
Description
Technical field
The utility model relates to the Physical Separation Technology field, the compound accurate dehydration filter core of moisture in particularly a kind of filtering insulation oil product.
Background technology
The filtration means that insulation oil dehydrating at present purifies mainly are vacuum methodes, and it exists equipment volume huge, complex structure, manufacturing difficulty, and need powerful firing equipment, the problem that use cost is high.
The present vacuum method treatment facility that generally uses utilizes the different operation principle of oil and water boiling point under the low pressure state, and the boiling point of water can be reduced to 60 ℃ of boilings and vaporize to realize water-oil separating under the low pressure state.Thus, need oil water mixture is heated during the operation of vacuum method treatment facility, need expend a large amount of electric power.Its environment for use also is subject to many limitations.
Summary of the invention
The utility model purpose is the accurate dehydration of a kind of insulating oil of a design filter core, and it gathers the knot dehydrating function and adsorption dewatering is an one, and the brand-new precision dehydration filter core that use cost is cheap is effectively to overcome above-mentioned drawback.
Specifically, a kind of accurate dehydration of compound insulating oil filter core of filtering insulation water content in oil is by filter core housing, the coalescent layer of breakdown of emulsion, dehydration layer and divide water screen to constitute; The dehydration layer is contained in the middle of the filter core housing, and the coalescent layer of breakdown of emulsion is contained in the entrance point of filter core housing, divides water screen to be contained in the port of export of filter core housing.
The dehydration layer is constituted or is made of the graininess hydroscopic high-molecular resin by bombax cotton parcel hydroscopic high-molecular resin.
The coalescent layer of breakdown of emulsion is a modified glass-fiber.
Dividing water screen is that the stainless (steel) wire that has sprayed polytetrafluoroethylene (PTFE) constitutes.
The method or the filling graininess hydroscopic high-molecular resin of the coalescent layer of the modified glass-fiber breakdown of emulsion that the utility model adopts wood composite cotton fiber parcel hydroscopic high-molecular resin, utilize effectively insulate free state, emulsification attitude, solubilised state moisture in the oil product of filtering of the powerful hydrophilic absorbability of the coalescent layer of modified glass-fiber breakdown of emulsion coalescent function of its breakdown of emulsion and hydroscopic high-molecular resin, a kind of to gather knot dehydrating function and adsorption dewatering be one and provide, the low modest brand-new precision of the use cost filter core that dewaters.
The utility model compact conformation is reasonable, uses simply the performance brilliance.The precision dehydration filter core of compound coalescent dehydration, adsorption dewatering function, it has solved the micro-moisture that exists in the present domestic insulation oil product can't an accurate difficult problem of handling, and makes user's insulation oil product obtain being up to the dehydrating effect of 2-5ppm (PPM).
Description of drawings
Fig. 1 is a side-looking structural representation of the present utility model;
The specific embodiment
Further specify structure of the present utility model and working method below in conjunction with accompanying drawing.
The accurate dehydration of insulating oil filter core, it is mainly by filter core housing 2, the coalescent layer 1 of modified glass-fiber breakdown of emulsion, cylindrical shape dehydration layer 3 that bombax cotton parcel hydroscopic high-molecular resin constitutes or graininess hydroscopic high-molecular resin dehydration layer 3, the stainless steel that has sprayed polytetrafluoroethylene (PTFE) divides water screen 4 to constitute.Dehydration layer 3 is contained in the middle of the filter core housing 2, and the coalescent layer 1 of breakdown of emulsion is contained in the entrance point of filter core housing 2, divides water screen 4 to be contained in the port of export of filter core housing 2.
In the utility model, the moisture oil product coalescent breakdown of emulsion layer 1 of modified glass-fiber of flowing through enters filter housing body 2, emulsification attitude water in the oil is broken out, small hydrone gathers into the bigger globule, moisture oil product is again by being installed on bombax cotton parcel hydroscopic high-molecular resin or filling graininess hydroscopic high-molecular resin layer 3 in the filter housing body, moisture is fully tackled guiding by bombax cotton and is adsorbed by hydroscopic high-molecular resin, the micro-moisture that is not in time adsorbed is blocked when flowing through branch water screen 4, thereby is adsorbed once more by the high-efficiency dehydration layer.Oil product after filtering means dehydration purifies flows out the filter housing body through minute water screen from oil-out, finishes the fluid filter dehydration process.
After the hydroscopic high-molecular resin of bombax cotton parcel or the diffusing shape particle hydroscopic high-molecular resin layer of filling suctioned moisture, hydroscopic high-molecular resin expanded closed, and filter core pressure reduction increases, and needed more renew cartridge this moment.
The utility model is mainly used in removing of micro-moisture in the power industry insulation oil product, also can be used for dewatering of hydraulic oil, machine oil, turbine wet goods lubricating oil product, other liquid substances.
