The invention relates to the field of cleaning liquids and gases from pollution and can be used in the coal, chemical, microbiological and other areas of the national economy.

The purpose of the invention is to increase the degree of purification.

Figure 1 shows the continuous hydrocyclone, a general view in section; figure 2 - section aa in figure 1.

A continuous hydrocyclone consists of a tangential pipe 1 for supplying the source liquid, connected to a distribution chamber 2, which is connected to a cylindrical body 3 with pipe 4 for removing impurities. In the lower part of the housing 3 there is a cylinder-shaped insert 5 with holes 6, which is fastened to the housing 3 by holders 7. A central tube 8 is coaxially mounted to the housing, to which are connected funnels 9 aligned with the edges of the holes 10. The central tube 8 is connected with pipe 11 drainage.

Prismid hydrocyclone works as follows.

Fluid is supplied through pipe 1 tangentially to distribution chamber 2, in which it acquires the azimuth direction of motion. Further, the fluid enters the housing 3 of the apparatus, where the rotation of the fluid increases. Since the width of the gap between the housing 3 and the tube 8 is small, there is a rapid separation of particles

on the wall of the casing 3. The particles roll down and fall into the gap between the insert 5 and the casing 3. Due to the reduction of the width of the gap, as well as due to the reduction of the radius, the total flow through the gap decreases. The heavy particles move along the walls of the casing 3, and the liquid layers along the insert 5 and udzhshsya through the holes 6. The remaining unseparated particles in the cylindrical part are separated on the surface of the insert 5 and dropped to the nozzle 4. The cleaned liquid is removed through the holes 10 in the central tube 8. The presence of funnels 9, set at an angle of 15-30 to the vertical, allows you to first remove the most purified liquid layers located in the central part. Further, the liquid enters the pipe 1I and is withdrawn from the apparatus. At the same time, in order to increase the degree of purification, the stream from the distribution chamber 2 first enters the working zone (cylindrical zone, where there are no walls of the insert 5), where all large and small particles are separated and most of the fineness is separated. The separated particles are removed into the gap between the walls of the insert 5 and the housing 3. Thus, in the area between the wall of the insert 5 and the cylindrical tube 8 large particles do not get, the movement of which causes vortex formation, i.e. To create a region without vortex formation, it is necessary to have a working zone in the cylindrical part of the body, where there is no cylindrical insert 5, which

does not allow large particles to penetrate into the area without vortex formations, and the central tube 8 with openings and with funnels 9, which are installed with large bases upwards and conjugated with openings in the tube 8. The presence of this area allows to obtain a new effect - separation of fineness.

The separation process in the proposed apparatus can be divided into three stages: the separation of large and small particles in the working area on the wall of the housing 3; sedimentation of particles without disturbances and loosening of particles in the gap between the walls of the insert 5 and the housing 3 with the removal of part of the fineness in the region between the walls of the insert 5 and the tube 8; Separation of tonin in an irrotational rotating region and removal of the clarified liquid.

It has been found that the optimum range of ratios of the diameter of the central tube 8 to the diameter of the cylindrical part of the body 3 is 0.1-0.2.
