Description

The proposed technical solution relates to combined devices for the separation of heterogeneous liquid media. The device can be used in agricultural land reclamation, in particular in drip irrigation, micro irrigation and sprinkling systems, as well as in other areas of industry and the national economy during water treatment or water treatment.

A hydrocyclone is known, comprising a housing including mating cylindrical and conical shells, a tangential inlet for supplying the initial product, coaxially located drain pipes with the formation of an annular gap between them, respectively, for outputting light and intermediate products, a chamber for collecting light intermediate products, and a sand pipe for output heavy product (Shestov R.N. Hydrocyclones. - L.: Mechanical Engineering, 1967. - 78 pp. - p. 17, Fig. 10).

A disadvantage of the known technical solution that impedes the achievement of the specified technical result is the lack of a filter element in the hydrocyclone, as a result of which the problem of removing finely dispersed impurities from water is not solved.

A hydrocyclone is known, comprising a housing including mating cylindrical and conical shells, a tangential inlet for supplying a starting product, a drain pipe for outputting a light product, a sand pipe for outputting a heavy product, a filter element and a slurry collector, the conical shell having a breaker device rigidly fixed to a movable rod, and a guiding element, and the filter element is made in the form of a semipermeable membrane fixed in a cylindrical shell (Patent p. m. No. 40015, B04 5/22, publ. 27.08.2004).

Reasons that impede the achievement of a given technical result include the impossibility of removing an intermediate product from the water with a density lower density of the light product and a fraction larger than the cell size of the filter element, i.e. pop-up impurities, as well as the complexity of the design and operation of the hydrocyclone.

The closest technical solution for the totality of features to the claimed device and adopted for the prototype is a hydrocyclone containing a housing including a mating cylindrical and conical shells, a tangential inlet for supplying the initial product, a drain pipe for outputting a light product, equipped with a filter element of different porosity, the outer surface of which equipped with a continuous fleecy cylindrical surface formed by needle elements, and a sand pipe for outputting heavy product (RF Patent No. 2180272, B04C 5/12, 9/00, publ. 10.03.2002).

The reasons that impede the achievement of a given technical result include the impossibility of removing an intermediate product from water with a density of a lower density of a light product and a fraction greater than the cell size of the filter element, i.e. pop-up impurities.

The task to which the proposed technical solution is directed is to improve the quality properties of irrigation water.

The result of the proposed technical solution is to increase the efficiency of cleaning irrigation water from pop-up impurities.

The set result is achieved in that the hydrocyclone comprising a housing including mating cylindrical and conical shells, a tangential input for supplying a starting product, a drain pipe for outputting a clarified product, equipped with a filter element with a filtering side surface, and a sand pipe for outputting a heavy product, and equipped with a cylindrical partition, immersed on the upper edge of the tangential input and installed coaxially with the drain pipe with the formation of an annular gap, placed on the disk, forming a chamber for collecting a light product with a density of a lower density of the clarified product and a fraction greater than the cell size of the filter element, which is placed on top in a cylindrical shell, the camera is equipped with an additional drain pipe for outputting a light product.

Equipping a hydrocyclone with a cylindrical partition, immersed on the upper edge of the tangential input and installed coaxially with a drain pipe to form an annular gap placed on a disk forming a chamber for collecting a light product on top of the cylindrical shell, allows you to remove pop-up impurities from the clarified product (light product).

Water from surface sources contains a certain amount of floating impurities - organic colloids, plankton, oil products, which negatively affect such quality indicators of irrigation water as color, turbidity, contribute to the overgrowing of drip tapes of drip irrigation systems, clogging of emitters.

Pop-up impurities entering the hydrocyclone with irrigation water, under the action of centrifugal force, move from the periphery (body wall) to the drain pipe to withdraw the clarified product. Through the annular space between the drain pipe and the cylindrical partition placed on the disk, the pop-up impurities are discharged into the chamber for collecting the light product, from where they are removed through an additional drain pipe for the output of the light product. The clarified product is discharged through a drain pipe equipped with a filter element with a filtering side surface. A heavy product, characterized by a density of a higher density of water, is removed through a sand pipe.

This behavior of particles of different densities in a centrifugal field of a hydrocyclone is due to the fact that particles with a density of a higher density of water are concentrated near the wall of the apparatus body, with a density of a lower density of water - closer to the axis of the apparatus. Since the drain pipe for outputting the clarified product is equipped with a filter element with a filtering side surface, particles of pop-up impurities with a fraction larger than the cell size of the filter element, moving in a centrifugal flow from the housing wall to the axis of the apparatus, will be concentrated at the filtering side surface of the drain pipe. Under the action of centrifugal force, particles with a density of a lower density of the clarified product and a fraction greater than the cell size of the filter element (light product) will float and, moving along the annular gap formed by the cylindrical partition placed on the disk and the drain pipe, will be removed through an additional drain pipe in the chamber to collect a light product. In FIG. 1 shows a general view of a hydrocyclone.

The hydrocyclone contains a housing including mating cylindrical 1 and conical 2 shells, a tangential inlet 3 for supplying the initial product, a drain pipe 4 for outputting the clarified product, a filter element with a filtering side surface 5, a sand pipe 6 for outputting a heavy product, a cylindrical partition 7 installed with the formation of an annular gap 8, placed on the disk 9, a chamber 10 for collecting light product, an additional drain pipe 11 for outputting a light product.

The hydrocyclone works as follows: irrigation water enters through a tangential inlet 3 into the cylindrical shell 1 of the hydrocyclone body. The flow in the hydrocyclone is swirling, a heavy product (coarse impurities) with a density of a higher density of water, striking against the walls of the body, is lowered along the conical shell 2 and is discharged through the sand pipe 6 to output a heavy product. A stream of water with finely divided impurities with a density of higher density of water passes through the filter element with a filtering side surface 5, while finely dispersed impurities are captured by the filtering side surface, and clarified water is discharged through a drain pipe 4 to discharge the clarified product.

A light product with a density of lower density of the clarified product and a fraction greater than the cell size of the filter element (pop-up impurities), moving in a centrifugal field with a stream of water, are sent from the periphery (body wall) to the side filter surface of the drain pipe. Then, through the annular gap 8, formed by a cylindrical partition 7, placed on the disk 9, and a drain pipe 4 for outputting the clarified product, pop-up impurities are discharged into the chamber 10 for collecting light product and are discharged through an additional drain pipe 11 for outputting the light product.

Thus, the hydrocyclone of the proposed design makes it possible to purify water from coarse and finely dispersed impurities, as well as emerging impurities with a density of a lower density of the clarified product and a fraction greater than the cell size of the filter element, which contributes to an increase in the efficiency of water purification and, accordingly, improvement of its qualitative properties.
