Abstract

The invention relates to the purification of petroleum fuels and oils from mechanical admixtures of water. The aim of the invention is to increase the efficiency of cleaning oil products from water. The filtering element, made on the basis of water-coagulating material, is placed between the annular partitions and the perforated frame, the height of the annular fins being the same. sort to less than the height of the filter element. In order to prevent the removal of microdroplets of water by the flow of the liquid being cleaned, in the lower part of the perforated frame there is installed a radially corrugated conical plate, ob., Which is turned by a vertex to the perforated frame, and the corrugations are made spiral. 1 C.p. f-ls, 2 ill.

Description

The invention relates to the purification of petroleum fuels and oils from mechanical impurities and water and can find applications in the chemical refining, automotive and other industries ...;

The aim of the invention is to increase the efficiency of cleaning oil products from water. . :.

In FIG. 1 shows a general view of a filter separator; Fig. 2 is an exemplary embodiment of a filter element.

The filter separator consists of a housing 1, inlet and outlet pipes 2 and 3, a horizontal plate 4 and a horizontal partition 5 with a hole in the center. The plate 4 is located above the partition 5, and on the periphery has perforation. On the plate 4 and in the upper part of the housing 1, annular partitions 6 and 7 are alternately fixed, with gaps between the upper part of the housing 1, the plate 5 and the annular partitions b and 7, and the filter element 8 is located between the annular partitions 6 and 7. and a perforated frame 9 and is made of a water-agglomerative material, for example polyurethane foam (one, one of its variants is shown in Fig. 2). The filtering element 8 is made in the form of a disk on which ring slots are made alternating to the upper part, the height of which corresponds to the height of the ring partitions b and 7, and the distance between the slots-1, the distance between the ring partitions 6 and 7. In the lower part of the perforated frame 9 is installed a radially corrugated cone plate 10 for discharging microdroplets of water into the settling zone of the filter. Moreover, in order to increase the coagulation time of water droplets during their movement along the corrugations of the conical plate 10, the corrugations are made spiral. At the bottom

part of the housing 1 there is a reflective plate 11, which prevents the capture of water from the settling zone and its removal by the flow of the liquid to be cleaned. Sludge is discharged through drain plug 12.

The filter separator operates as follows,

The oil being refined through the inlet pipe 2 enters the housing 1, through the perforation of the plate 4 enters the filter element, passes through it sequentially, flowing around the annular partitions 6 and 7, passes through the perforated frame 9 and is removed to the consumer. When the petroleum product moves through the filter element 8, coagulation (strengthening) of microdroplets of water occurs. Moreover, the duration of this process is increased due to the labyrinth movement of the fluid flow. This allows the microdroplets of water to reach the outlet of the filter element of 8 sizes, ensuring that they fall onto the conical plate 10. When the microdroplets get into the corrugations of the plate 10, the water droplets roll along them into the settling zone. Moreover, the process of coagulation of microdrops continues also when they move along the corrugations, and the execution of corrugations in the form of a spiral allows to increase the coagulation time of microdrops, and / and, therefore, reduce the likelihood of their removal by the flow of the liquid being cleaned.

The use of a filter separator with annular partitions and a conical corrugated plate allows the labyrinth movement of the flow of the liquid to be cleaned and, therefore, the coagulation time of microdroplets of water can be increased, and the coagulation process continues even after the liquid exits the filter element, which improves the efficiency of filter water separation -separator in general.
