Abstract

The invention relates to the purification of liquids and their simultaneous heating, in particular pressure hydrocyclones, and can be used in the mining, chemical and other industries. The purpose of the invention is to provide simultaneous intensification of the cleaning and heating of the liquid. The hydrocyclone includes a housing (K) 1 with a cylindrical 2 and a conical 3 parts, a heat exchanger (T) 4 having an inlet 5, a tangential inlet 6 and an outlet 7 nozzle, a nozzle 8 for removing sludge. In the outer tube 9 T 4, inclined holes 10 are made, which can be distributed below the hole 11 of the nozzle 6. The angle α of inclination of the holes 10 to the plane perpendicular to the vertical axis K 1 is determined from the ratio β / 2 * 98AARCTGH / (D / 2 ), where β is the angle of the conical part K 1

H and D are the height and diameter of the cylindrical part K 1. The liquid being cleaned flows through the nozzle 6 into the K 1, twists and undergoes separation. At the same time through the pipe 5 in T 4 and then in K 1 through the holes 11 enters the coolant. As a result of contact between the fluid and the coolant, the efficiency of the centrifugal field increases and the flow temperature increases. 3 il.

The hydrocyclone contains a thermally insulated housing 1, comprising an upper cylindrical 2 and lower conical 3 parts with a coaxially mounted heat exchanger 4, having an inlet 5, and tangential inlet and coaxial outlet nozzles 6 and 7 located in its upper cylindrical part 2, respectively the lower conical part 3 nozzles 8 for removal of sludge. Tangential inclined holes 10 are made in the outer tube 9 of the heat exchanger 4, and the angle oi of the slope of the axial line of each of which to the plane B, the perpendicular vertical axis 0-0 {of the hydrocyclone-heater, is determined from the ratio

With the internal cavity of the thermally insulated housing 1 below the level G of the opening 11 of the tangential inlet 6, and the direction of exit of the coolant from them and the direction of rotation of the fluid flow can coincide.

Hydrocyclone works as follows.

A stream of fluid subjected to cleaning 5 enters through the tangential inlet nozzle 6 through the opening 11 into the cylindrical part 2 of the heat-insulated body 1 and receives rotational movement around the outer pipe 9 of the heat exchanger 4. After this, heat carrier (steam) flows through the inlet nozzle 5 which comes out of the tangential inclined holes 10 (the ratio of their length to diameter, it is advisable to choose ... 4) made in the outer tube 9. The tangential inclined holes 10 communicate with the internal cavity eploizolirovannogo hydrocyclone body 1 below the level of the openings 11, T tangential inlet 6. The coolant forms a rotating ring, the direction of rotation of which coincides with the direction of rotational movement of the liquid. As a result of direct contact of the fluid and the coolant, a simultaneous increase in the efficiency of the centrifugal field and an increase in the temperature of the flow are provided. The heated flow, moving further along a helical spiral along the inner wall of the cylindrical part 2 of the thermally insulated body 1, is directed to the conical part 3, where it changes the direction of movement and moves to the central part of the hydrocyclone-heater. The sediment released in the near-wall zone and the most saturated is suspended5

With liquid substances, a portion of the liquid is periodically removed from the device through the pipe 8 for collecting sludge. The cleaned and heated liquid, moving upward along the coaxial outlet nozzle 7, which is the inner wall of the heat exchanger 4, is further heated and supplied to the consumer.

Thus, the implementation of tangential inclined holes in the outer tube of the heat exchanger allows, along with the simultaneous intensification of cleaning and heating the fluid, to make the device more compact.

In addition, the heating of the fluid directly in the cleaning process in the hydrocyclone itself due to the direct contact of the fluid and the coolant allows to simplify and cheapen the construction and operation of closed water supply cycles and to increase their efficiency.
