(54) HYDROCYCLONE FOR CLEANING

Wastewater .

one

The invention relates to the treatment of agricultural wastewater containing mechanical impurities and residues of organic origin, such as plankton and leaves, as well as the purification of three-phase liquid, such as industrial waste water containing components with a density that is larger and less than the density of the working medium.

Known hydrocyclone, comprising a cylindrical-conical case with an inlet pipe and nozzles for drainage of clarified water and a separate slot, a filter element placed inside the drain 1.

A water purifier is also known, including a cylindrical-conical case with a sludge discharge pipe and a drain pipe plugged from above, which is additionally equipped with a filtration chamber made in the form of a casing with a filter partition 2 placed inside it coaxially to the drain pipe.

The disadvantages of these devices are the clogging of the filter element by floating bodies and the absence of a nozzle for their removal, which leads to a decrease in efficiency and a decrease in productivity.

The closest in technical essence and the achieved result to the image is a hydrocyclone, the contents of a cylindrical body with a tangential inlet nozzle and nozzles) of mechanical impurities, floating bodies and clarified liquid, concentrated inside the cylindrical body of the cylinders, the inside of which is made perforated 3.

The disadvantage of this device is the low quality of wastewater treatment.

The purpose of the invention is to increase the quality of wastewater treatment.

The goal is achieved by

Then the hydrocyclone is provided with a collector (the clarified liquid and the filtering load placed between the cylinders; the outer cylinder is made perforated, and the collecting

perishable fluid is located between the building and the outer cylinder.

In addition, in order to improve the quality

Claims (3)

After washing the filtering load, it is possible to change its volume; the hydrocyclone is equipped with a pressure ring, installed 1 Vltezhnyy cylinders with the possibility of vertical movement. In this case, the branch pipe for discharging floating bodies is made in the form of a conoidal attachment attached by a large base to the cylindrical part of the body. FIG. 1 shows a hydrocyclone, a general view; in fig. 2 shows section A-A in FIG. 1. A hydrocyclone includes a body consisting of a cylindrical 1 and a conical 2 parts, a tangential inlet 3, a nozzle for discharging floating bodies 4, a sand hole 5 perforated, cylinders concentrically mounted inside the body 6. Between the perforated cylinders 6 a chamber 7 is formed, which provided with a wash liquid supply manifold 8 with water outlets 9, a retaining annular lid 10, equipped with pins and bolts 11 connected to it, and a collector for discharge of clarified liquid 12 with a branch pipe 13. Collector the washing liquid is provided with an inlet 14. The inner chamber is loaded with filtering materials 15. The hydrocyclone operates as follows. The chamber 7 is loaded with filtering materials for about 80% of its height and compressed with a retaining ring cover 10 with the help of bolts 11. Then, the original waste water is fed through the tangential inlet nozzle 3. The flow of a three-phase fluid, hitting a hydrocyclone, acquires a strong rotational motion. , Under the action of centrifugal forces, the liquid is separated into phases. Solid particles thrown to the top of the cone are discharged through the sand hole 5, and light floating bodies, concentrated along the axis in the upper part of the internal flow, are discharged through the nozzle 4, while through the internal and external perforated walls 6 and filtering materials 15 Filtration of clarified liquid. After the filter, the purified liquid enters the chamber 12 and is discharged through the nozzle 13. The entrance at high speed through the nozzle 3 water constantly washes the filter surface of the chamber 7, discards mechanical impurities to the top of the cone 5, and the floating bodies - to the hydrocyclone axis with their discharge through pipe 4, eliminates clogging of the filter surface and, thus, contributes to the achievement of high-quality cleaning fluid and increase the efficiency of the hydrocyclone. Flushing of filtering materials is carried out. To do this, the hydrocyclone is disconnected from operation, the retaining annular lid 10 is lifted with the help of bolts 11, after which clean water is let in to the collector 8 under pressure. The liquid streams flowing out of the holes 9 with a high velocity lead to random random chaotic movement of a particle of filter material and it is washed in its state. The application of the proposed hydrocyclone will allow for better cleaning, increase efficiency and reduce the cost of wastewater treatment in comparison with the known settling method by 2-.3 times. Claim 1. Hydrocyclone for wastewater treatment. containing a cylindrical housing with a tangential inlet and outlet pipes for mechanical impurities, floating bodies and clarified liquids, concentrically mounted cylinders inside the cylindrical part of the body, the inner of which is perforated, characterized in that, in order to improve the quality of wastewater treatment, it is equipped with a collection header clarified liquid and filtering load placed between the cylinders, while the outer cylinder is perforated, and the collection collector is clarified fluid is located between the hull and the outer cylinder. 2. The hydrocyclone according to claim 1, characterized in that, in order to increase the quality of washing of the filtering load due to the possibility of changing its volume, it is equipped with a pressure ring installed between the cylinders with the possibility of vertical movement. 3. A hydrocyclone according to claim 1, characterized in that the branch pipe for discharging floating bodies is made in the form of a conoidal attachment attached by a large base to the cylindrical part of the body.
