SUBSTANCE: cyclone unit has cylindrical shell, inlet branch pipe, taper shell, dirt accumulator and outlet branch pipe. Mounted inside cylindrical shell are narrowing flat guides of nozzle having taper section for increase of rate of rotation of liquids. EFFECT: enhanced efficiency of cleaning. 2 cl, 2 dwg

Description

 The invention relates to cleaning agents and can be used in the engineering industry and other fields for cleaning liquids from solid polluting particles, for example, for treating water used in cooling systems of diesel engines.

 Known cyclone devices that are widely used in industry for cleaning air and gases from dust and other suspended particles [1, 2, 3]. The rotation of the dust and gas flow in them is carried out either due to a radially arranged spiral or tangential inlet, or, with the central location of the inlet pipe, through the use of special swirl or socket type swirls.

 The liquid medium is more dense and viscous, therefore, such devices are not suitable for cleaning liquids due to the low speed of rotation of the stream.

 The aim of the invention is to increase the speed of rotation of the fluid flow in a cyclone device to improve cleaning efficiency.

 This goal is achieved by the fact that in a cyclone device containing a cylindrical body, a tangentially located inlet pipe, a conical body, a dirt accumulator and an outlet pipe, additionally, tapering flat guide nozzles having a conical section are installed inside the cylindrical body.

 The device diagram is shown in figure 1.

 The proposed cyclone device contains a cylindrical housing 1, in the upper part of which the inlet pipe 2 is tangentially mounted. On top of this housing is closed by a cover 7 through which the outlet pipe 5 passes. The lower part of the cylindrical housing 1 is connected to a conical housing 3, the narrow end of which is included in the pollution accumulator 4. Between the inner wall of the cylindrical body 1 and the outer wall of the outlet pipe 5, guide nozzles 6 are made, made of two half washers connected together, shown in FIG. 2.

 The device operates as follows.

 The contaminated liquid is supplied under pressure through the inlet pipe 2 into the cylindrical body 1. Due to the tangential location of the inlet pipe, it acquires a rotational movement and then enters the inlet slots of the flat tapering guide nozzles 6, where an increase in the outflow speed and, consequently, an increase in the speed of rotation of the flow inside the cylindrical housing 1. Suspended particles of contaminants are discarded by centrifugal force on the inner walls of the cylindrical housing and spiral movement tucking to the conical body, and then into the accumulator of pollution. The purified liquid is displaced through a centrally located outlet 5.
