1. Filter - a water separator containing a housing with inlet, outlet and drainage pipes, a filter element consisting of a filtering, coagulating, drainage and water-repellent layers, characterized in that in order to improve the quality of cleaning, increase throughput and ensure guaranteed operating life of the housing, equipped with a gas collector with a gas outlet, and each layer is made in the form of a separate element - filtering, coagulating and separating.

2. Filter - water separator according to paragraph 1, where the individual elements (filtering, coagulating and separating) 7) are installed in the housing both horizontally and vertically with a specific geometry.

3. Filters - water separators according to paragraphs 1.2 with a throughput of 5 to 240 m. Bsub./hour, which ensure the purification of fuel or other petroleum products from free water to a residual concentration of less than 0.0015% in May.

4. Filters - water separators according to paragraphs 1, 2, 3 with an additional water sorbing element, which allows for complete cleaning of the fuel from free water.

Such filters - water separators are intended for the purification of petroleum products, including motor and aviation fuels, as well as other liquids that are not miscible with water. During the cleaning process, filtering from mechanical impurities to a filter fineness of less than 1 micron and separation of free water to its absence, depending on technological operating conditions, water separator filters can be made in horizontal or vertical versions.

A known filter - water separator (1), which is a housing with inlet, outlet and drain pipes. A multilayer filter element consisting of a filtering, coagulating filter element is installed in the housing. drainage and water repellent layers. The filter layer is designed to capture mechanical (solid) particles. The coagulating layer 3 makes dispersed - distributed water droplets to sizes that allow them to flow down the drainage layer. The water-repellent layer plays the role of a barrier for the smallest drops of water that have not had time to coagulate before. The main disadvantages of this scheme are the significant dependence of the output characteristics of the cleaning on the flow rates of the filtered liquid and the need to replace the entire filter element when one of the layers fails.

The closest in technical essence is the Faset filter-water separator (2), which consists of a body with inlet, outlet and spill nozzles, a filter element, including filter and coagulating layers and a water-repellent membrane in the form of a basket-like partition. However, the rather large size of this “membrane and the fact that its surface is combined with the pre-treatment zone of the filtered liquid does not allow us to expect long service life at high rates of water separation.

The proposed model of the filter - water separator is free from the inherent disadvantages of analogues and provides a long service life at high cleaning rates, while it allowed to create standard series of both vertical and horizontal versions taking into account different performance and operating conditions. This is achieved by the fact that in a case with inlet, outlet, overflow and gas outlet pipes, for certain geometry of arrangement and proper dimensions, individual elements are installed - a filter), a coagulating element and a separating element. The required number of such elements can be set depending on the throughput and the requirements for the liquid being cleaned. These elements divide the entire body cavity into zones: the first zone is the inlet, the second is the filtering zone from mechanical impurities, the third is the zone of coagulation of water drops, the fourth is the zone of separation of the filtered liquid from

free water, the fifth is the absorption zone of residual water until completely removed.

Figure 1 shows the operation diagram of the water separator filter in horizontal and vertical versions, with the following notation:

1. The case with a cover. 2.Inlet pipe. 3. Outlet pipe.

4. WATER TUBE. 5. Gas outlet pipe.

6. The filter element. 7. Coagulating element.

8. The separating element. 9. The catchment. 10. Gas collector.

11. Residual water absorber.

In the diagram, Roman numerals indicate the numbers of the filtration zones, and arrows indicate the direction of flow of the filtered fluid.

A stream of filtered fluid under pressure is directed through the pipe /pos.1/ and forms the so-called first zone 1. Then, passing through the filter element / pos.6/, the fluid flow enters zone 11, while filtering from mechanical impurities to a filter fineness of less than 1 μm occurs. In zone 11, the flow enters the filter-coagulator element / pos. 7 /, where there is an enlargement of drops of free water that flow into the water collector /pos.9 / and are discharged through the spillway / pos.4 /. Next, the flow passes to zone 111 and is directed through the separating element / pos.8/ to zone 1U, where the content of free water in the stream is less than 0.0015% in May. from where they are output through the absorber / pos. 11 / in the outlet pipe / pos. З/ - zone U. Gaseous components of the filtered liquid are collected in the gas collector / pos. 10 / and are discharged through the gas outlet pipe / pos.Z/. Filtration is carried out at pressures of 6-12 kg / cm2 and at temperatures from +50 C to -50 C.

Depending on the required throughput and technological features of operation, the following types of filters - water separators are installed:

Horizontal filters - water separators are equipped with filtering, coagulating or filtering coagulating and separating elements, and, if necessary, absorbing nozzles.

All the above filters - water separators allow you to clean liquids that are not miscible with water to a nominal filter fineness of less than 0.1 microns. and ensure complete separation of free water. With a pressure drop across the filter - water separator more than 2.0 kg / cm2 replacement of elements with new ones is proposed - this happens after three years of operation. In some situations, it makes no sense to use a water-absorbing nozzle - then the maximum content of free water in the filtered liquid is guaranteed no more than 0.0015% wt.

The proposed model of fi-liter - water separator allows you to have a set of specific samples for different capacities - 5, 30, 40, 60, 90, 120, 150, 240 cubic meters per hour, while ensuring filter fineness from mechanical impurities of less than 1 micron, full separation of free water and long service life.
