Diesel oil water separation precipitator

Technical field

The utility model relates to a kind of purification plant that is fit to be configured in the internal-combustion engine liquid fuel transporting system, particularly relates to a kind of diesel oil water separation precipitator.

Background technique

Often be mixed with impurity, moisture, bacterium and other pollutant in the commercially available diesel fuel, for the optimum performance that obtains diesel engine with prolong its working life, must take measures with the water separation in the diesel oil fall, foreign material filter out.Generally use the diesel oil water separation precipitator that is different from general filter cleaner that diesel oil is carried out above-mentioned processing at present.Described diesel oil water separation precipitator of a great variety, structure is different, but they all exist water separation efficient and the low defective of foreign material filter efficiency.

The model utility content

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of water separation efficient and the high diesel oil water separation precipitator of foreign material filter efficiency are provided.

For achieving the above object, the utility model provides a kind of diesel oil water separation precipitator, its structure is: the upper open end of housing has the thread plate sub-assembly, lower open end has valve seat, the element kit of center band honeycomb duct is arranged at inner chamber top, element kit comprises inside and outside socket and the screen cloth pipe that closely reclines, inner filter core, outer filter core, inner filter core adopts two-layer absorbent material, outer filter core adopts the filter paper that rolls through folding, connect filter block by the thread plate sub-assembly on the housing, connect drain valve by valve seat down, establish hand fuel pump on the filter block, side joint oil inlet pipe and oil outlet tube, oil inlet pipe, oil outlet tube is the oil-feed oil circuit in filter block respectively, fuel-displaced oil circuit communicates with the housing inner chamber, and drain valve is provided with level sensor.

Described absorbent material is a nonwovens, and described filter paper folds with star fashion and rolls.

Described level sensor is in the inner chamber bottom of housing, and two wires in the level sensor pass drain valve and reach outside the housing.

When the utility model uses, must be installed in the diesel oil transporting system of diesel engine and be in before fuel pump and the oil sprayer.

Below by introducing concrete using process of the present utility model the beneficial effects of the utility model are described:

The oil-feed oil circuit of diesel oil in oil inlet pipe, filter block that is mixed with water and foreign material in the diesel oil transporting system enters in the housing.Water in the diesel oil at first flows through outer filter core, adopt the filter paper that rolls through folding because of outer filter core, numerous capillary holes is arranged in it, like this, mutual affine cohesion when utilizing fine liquid particles to pass through the capillary hole, make the emulsified water aggegation in the diesel oil become free water, this free water major part is vaporific little water droplet; Because of inner filter core, outer filter core closely recline, inner filter core adopts two-layer absorbent material again, and adsorption performance is preferable, and like this, described free water is flow through inner filter core and, once more cohesion adsorbed by inner filter core, makes the globule of its aggegation Cheng Gengda.

Water in diesel oil obtains in the process of twice cohesion by outer filter core, inner filter core, foreign material in the diesel oil obtain twice filtration by outer filter core, inner filter core successively with flowing of diesel oil, water, adopt the filter paper that rolls through folding because of outer filter core, numerous capillary holes is arranged in it, have the advantages that filter area is big, filter precision is high, inner filter core adopts two-layer absorbent material, its adsorption performance is preferable, like this, the hydrophoby foreign material by outer filter core, inner filter core fully adsorbs and stay afterwards in both, the then molten people of hydrophily foreign material is through in the resulting globule of twice cohesion.

Diesel oil, the globule (being dissolved with the hydrophily foreign material in it) through above-mentioned processing flow downward at the guide functions lower edge of water separation element-honeycomb duct screen cloth pipe.When diesel oil arrives the lower end of screen cloth pipe, because of the fuel-displaced oil circuit of housing inner chamber in filter block, oil outlet tube communicate with fuel pump and oil sprayer in the diesel oil transporting system, under the powerful pumping action of fuel pump, make its flow direction of pure diesel oil change, turn back from screen cloth pipe lower end and upwards to enter in the honeycomb duct, fuel-displaced oil circuit in filter block and oil outlet tube flow out, and finally enter in the diesel engine through fuel pump and oil sprayer again.And for the globule that is dissolved with the hydrophily foreign material, because of it has obtained enough speed in downward flowing, the proportion of diesel oil and water is different in addition, water is than great and diesel oil proportion is little, so the downward inertia of the described globule is much larger than diesel oil, like this, when the flow direction of pure diesel oil changes upwards, the described globule will continue to flow downward under action of inertia, make the described globule can overcome the surface tension of diesel oil and throw off in it, separate, and be deposited in the inner chamber bottom of housing.At this moment, the utility model can fall the water separation in the diesel oil effectively, foreign material filter out.

In sum, the utlity model has water separation efficient and the high advantage of foreign material filter efficiency.According to detection, water separation efficient of the present utility model is greater than 96%, and the foreign material filter efficiency is more than 92%.
