Description
Technical field
The present invention relates to a kind of large flow fuel oil filters and oil and water seperator, relate in particular to the separator of a kind of fuel oil of large discharge value and moisture, mechanical admixture, product of the present invention can effectively solve existing fuel oil and in transportation and storage process, sneak into the problem of moisture and impurity effect internal combustion engine, by mechanical filter means, improve fuel oil purity, reduce significant to the wearing and tearing of the elements such as oil pump, oil nozzle.The existence of moisture is also very harmful for fuel system for diesel engine, when fuel moisture content is larger, will cause engine misses, and power declines.Also can cause corrosion, wearing and tearing, the stuck combustion process that even can worsen diesel oil of internal-combustion engine components and parts.Because the sulphur content in Chinese Diesel is higher, when burning occurs, even can generate sulfuric acid corrosion engine components with water reaction.Traditional mode that dewaters is mainly precipitation, passes through funnel structure.Along with technological progress, internal combustion engine is to moisture and the higher requirement of the separated proposition of impurity, and high-quality fuel oil requires just need to adopt the filter core of high filtering precision and high score crystal degree.
Background technique
Internal-combustion engine is widely used in the main process equipments such as road transport vehicle, engineering machinery, boats and ships, generator set, and fuel oil is in storage, in the processes such as transportation, inevitably can sneak into the impurity such as moisture and solid particle, use with the fuel oil of the impurity such as moisture, fine solid particle and will make prematurely the fuel pump of precision element and oil sprayer etc. break down.For fear of or reduce the various faults occur because fuel oil quality is inferior, must before entering fuel pump and oil sprayer, fuel oil both to fuel oil, carry out contaminant filter, also the moisture separation in fuel oil must be removed, conventionally on in-line, install oil and water seperator additional with the impurity in filter fuel, separating oil contained humidity.
The principle of oil-water separation is to utilize the density difference principle of fuel oil and water, and because the density of water is greater than the density of fuel oil, the moisture in fuel oil is when by oil and water seperator, and moisture is separated and can be deposited on the bottom of oily-water seperating equipment.Must note timely draining in use.
Summary of the invention
The object of the invention is to provide a kind of deft design, be applicable to large traffic filtering with fuel emulsification water break milk separation function and mechanical admixture filtering function fuel oil filter, use the fuel oil filter of this structure, effectively moisture and the mechanical admixture in filtering fuel oil, improves the fuel qualities into internal-combustion engine.
For achieving the above object, the technical solution used in the present invention is: large flow fuel oil filters and oil and water seperator, its effective filtration fraction is by filtering breakdown of emulsion filter core and minute water filter core, dividing a water air guide sleeve to form, above-mentioned two filter bodies are installed on respectively in housing, described filtration breakdown of emulsion filter core is positioned at the breakdown of emulsion filter of filter assembly, within described minute, water filter core is installed in minute water filtration body, filter breakdown of emulsion filter core and formed by unlike material Multi-stacking compaction, be respectively from outside to inside mechanical admixture filter layer, demulsification layer, support structure net; Between the outside of minute water filter core and housing, be provided with air guide sleeve; Water storage device is positioned at the bottom of breakdown of emulsion filter and minute water filtration body, is provided with discharging valve and level sensor on water storage device.
It is disposable by the cleanliness after filter that the present invention adopts large flow secondary filter and minute water mode to improve fuel oil.
When product of the present invention is used, can be arranged in the Fuel Delivery System of internal-combustion engine and before fuel pump and oil sprayer, also can be connected separately use with diesel oil transfer pump.Below by the beneficial effect of introducing concrete using process of the present invention and describe product of the present invention.
The fuel oil that is mixed with water and foreign material in the Fuel Delivery System oil pipe of flowing through enters in filter by filler opening.First flow through the accurate contaminant filter layer being formed by materials such as chemical fibre or glass, nonwovens, high density filter paper.Fuel oil after filtering mechanical admixture is again by breakdown of emulsion layer, breakdown of emulsion layer be by PETG (english abbreviation is PET) material or glass fiber material or the Multi-stacking compaction of the two or mixing, made hydrophilic oleophobic material, its material itself has excellent hydrophily and innerly has numerous capillary holes.Like this, while utilizing fine liquid particles to pass through capillary hole and the mutual affine cohesion of water wetted material, after the emulsified water breakdown of emulsion that fuel oil is flowed through after breakdown of emulsion layer wherein, be aggregated into free water, this free water major part is little water droplet, collision is converged as larger-diameter water droplet mutually again, after the hole by centre post, enter water storage device, under Action of Gravity Field to water storage device bottom rapid subsidence.Fuel oil oil flow channel after demulsification preliminary minute water flows into a minute water filtration body cavity of resorption, the fuel oil entering after cavity of resorption makes progress in mobile process at the throat along between housing and air guide sleeve, the free state droplet of being taken the demulsification of wrapping up in by fuel oil mutually collides and condenses sedimentation again, thereby accelerates to separate from fuel oil.
On minute centre post of water filter element device in air guide sleeve of internal layer, centre post bottom is connected with center oil outlet, this minute water filter core makes material by the stainless (steel) wire double-coated teflon of corresponding density or teflon material forms, polarity is oleophilic drainage, with its rounding column single channel, divide water filter core, on minute water filter core, mount inlet is connected with center oil outlet.When fuel oil carries the separated filter screen of micro-moisture by minute water filter core, because screen material polarity is lipophilic-hydrophobic property, its micro-moisture containing is blocked in a minute top layer, the network of rivers.When micro-moisture gather a certain amount of after, start to form the globule, the globule is sedimentation downwards under Action of Gravity Field, finally falls in water storage device, pools together with the ponding of its bottom.It is inner that fuel oil after dehydration flows to minute water filter core, and by center oil outlet outflow filter, thereby obtain clean fuel oil.
The present invention's advantage compared with prior art: what existing fuel oil filter adopted in Separation of Water timesharing is the simple interception mode that blocks water; the effect for the free state moisture existing in fuel oil with quick separation; but the moisture of the emulsification state containing in fuel oil can not be effectively separated; often block in filter core; when oil water mixture accumulated amount surpasses after filter core volume; under certain pressure effect; the emulsified fuel of high-moisture can be broken through filter core and intercept water resistance and by filter layer, cause internal-combustion engine to be shut down suddenly.And the employing of this patent product is break milk separation and accurate interception mixed mode.Emulsified water in fuel oil is separated completely, and what sub-argument went out is pure moisture, and the fuel oil moisture content of passing through from filter is completely up to standard.
