Description

The invention relates to devices for the purification of hydrocarbon fuels (gasoline, kerosene, diesel fuel, etc.) from free water and mechanical impurities and can be used in the refining, automotive and other industries.

The aim of the invention is to improve the quality of purification of hydrocarbon fuels from water.

The goal is achieved by the fact that in the water separator filter comprising a housing with a lid, a clamping bolt, inlet, outlet and drainage nozzles, a spring-loaded filtering separating element including the outer and inner tubes, arranged sequentially in the course of the fuel by the filter, coagulating, water block fiber layers of the coagulating layer are arranged helically with respect to the inner tube of the filter element, moreover, fiberglass is used as the material of the coagulating layer, and Loknya into filaments arranged helically

Distinctive features of the proposed filter separator are: the threads of the coagulating layer are arranged spirally with respect to the inner tube of the filter element.

This arrangement of the filaments makes it possible to increase the trajectory of the fuel through the coagulating layer, and, consequently, the duration of the microdroplet of water in this layer. The emulsion moves along fibers that are spirally woven into the thread and in turn the thread is directed in a spiral. Therefore, the emulsion moves along the fibers in two spirals: the first is the thread, and the second is its spiral arrangement. This increases the trajectory of the droplet along the fiber several times and, accordingly, increases the coagulation effect.

Fiberglass is used as a material for the coagulating layer.

This is necessary because it is the structure of the fibers of the basis of glass cloth that allows one to obtain a spiral arrangement of fibers.

The spiral arrangement of fiberglass fibers in the coagulating layer together with the water coarsening layer and the falling direction of fuel flow together provide the necessary degree of fuel cleaning.

The drawing shows a General view of the proposed filter water separator.

A water separator filter comprising a housing 1 which is pressed against the lid 2 by a hollow bolt 3 and sealed with an annular gasket 4. Inside the filtering water separating element 5 consisting of a filtering layer 6, a coagulating layer 7, is placed. mi located at an angle to the vertical axis of the filter water separating element of the water reduction layer 8 with randomly located pores. Outside and inside, the layers of the element are fixed with glue to the tubes 9 of hydrophobic material, and from the ends - with covers 10 with openings for the entrance and exit of hydrocarbon fuel. The filter element to the housing cover is pressed through the rubber washer 11 by the spring 12 and is sealed by the ring 13. For the supply of contaminated hydrocarbon fuel serves as an inlet 14, and for discharging the cleaned fuel - an outlet 15. The water accumulated in the settling zone of the housing is discharged through drainage pipe 16. The stitching bolt 3 has a settling cavity 17, a tip 18, holes 19, and also a drain bolt 20.

Filter water separator works as follows.

Hydrocarbon fuel flows in a falling stream, through the inlet 14 to tip 18, and then the direction of movement is reversed, while under the influence of inertia forces large drops of water and mechanical particles are diverted into the settling zone of the hollow bolt 3. The fuel enters the filter a layer 6 of filtering separating element 5, where particles of mechanical impurities are trapped, then into a coagulating layer

7, where the microdroplets of water contained in the hydrocarbon fuel are adhered to glass fiber threads. Coalescing and increasing in size the droplets move along

helically arranged fibers down to the water consolidation layer.

In the water consolidation layer, the droplet sizes continue to grow into larger ones; these droplets exit with a flow from

the filtering water separating element is deposited in the settling zone under the influence of gravitational forces, and the fuel reverses the direction of movement and exits the filter housing through the outlet nozzle. Drops of water deposited in the settling zone are discharged outside through the draining nozzle 16.

The proposed filter water separator design will, compared with the prototype, reduce the water content of hydrocarbon fuels at the filter output by 8-10% due to an increase in the efficiency of coagulation of water microdroplets in the coagulating layer. The emulsion water content after the water separator filter is 0.001% or 10 g per ton of fuel. Reducing the water content in hydrocarbon fuel by 10% will increase the reliability of the fuel system,

for example, diesel engines by 10-15%.
