Description

one

The invention relates to the technical treatment of wastewater treatment of metallurgical enterprises, oil refineries, and others from precipitating and floating pollutants.

Known hydrocyclone, containing cylindrical housing with concentric cylinders, forming with the housing outer, located in the upper part of the housing, and the inner annular chamber.

However, in the known construction, the degree of purification of wastewater from floating contaminants is low due to the low rate of their floating (oil, cephalic products, etc.).

The purpose of the invention is to intensify the cleaning process.

This is achieved in that the outer annular chamber is divided by a partition into a diversion chamber and an inlet chamber in communication with the inner annular chamber, and the housing in the upper part is made with openings and is equipped with guide vanes.

At f.IG. 1 shows the proposed hydrocyclone in section; in fig. 2 is a section along A-A in FIG. one; in fig. 3-section along BB in FIG. one.

The hydrocyclone consists of a cylindrical body 1, having a tangential nozzle 2 in the lower cylindrical part. The upper part of the body is made with holes M and 3 and is equipped with guide vanes 4.

The annular chamber 5 of the inlet, located in the upper part of the body, has an inlet tangential nozzle 6 and is separated from the annular chamber 7 of the outlet by a partition 8.

Inside the housing 1 concentric to it, the income to the lower tangential nozzle 2, a cylinder 9 is installed, forming together with the diaphragm 10 and the partition 8 an inner annular chamber 11 open below, having a water-metering glass 12. The compressed air supply pipe 13 and the pipeline are connected to And

14 to remove excess air. There is a submerged shield in the upper part of the case.

15 and a funnel 16 with a discharge pipe.

Hydrocyclone works as follows.

The contaminated fluid enters the body simultaneously through two tangential nozzles 2 and 6. The fluid entering the annular inlet chamber 5 through the tangential nozzle 6, due to the presence of the holes 3 and the guide vanes 4, is distributed to several jets that are in the inner annular chamber 11 form waterfalls. The water level in the annular inner chamber (air cushion) is monitored by gauge glass 12 and regulated by pipelines 13 and 14. The jets, when dropped by the boiling energy, are buried below the water level in the inner annular chamber, taking with them dispersed. Air bubbles are then entrained by the rotating flow coming out of the tangenzial nozzle 2 and carried to the central part of the hydro cyclone, where they rise, carry pop-up contaminants with them, due to the presence of diaphragms 10, they are collected on the surface bounded by a submerged shield 15 and withdrawal it is from the hydrocycle through the funnel 16 with a discharge pipe.

The solid, heavier impurities under the action of a de-force-down force are pressed against the walls of the hydrocyclone and lowered into the coic part of housing I, and then removed from

him.

Subject invention

A hydrocyclone for wastewater treatment, comprising a cylindrical housing with concentric cylinders forming an outer housing placed in the upper part of the housing and inner annular chambers, characterized in that, in order to intensify the cleaning process, the outer annular chamber is divided by a partition into a chamber of outlet and a chamber the inlet communicates with the inner annular chamber, and the housing in the upper part is made with openings and is provided with guide vanes.
