Недостатком этой конструкции вл етс сравнительно невысока степень сгущени раздел емой суспензии, невозможность организации отвода содер- 20 жащихс в жидкости газов и одновременного проведени процессов сгущени и выпаривани жидкой фазы сгущенного потока. , Известен также гидроциклон, содер- жащий цилиндроконический корпус, тангенциальный питающий патрубок, патрубки отвода осветленной и сгущенной фракции и патрубок отвода газовой фазы . .30The disadvantage of this design is the relatively low degree of condensation of the separable suspension, the impossibility of organizing the removal of gases containing in liquid and the simultaneous processes of condensing and evaporating the liquid phase of the condensed stream. Also known is a hydrocyclone containing a cylindrical housing, a tangential supply nozzle, nozzles for removing the clarified and thickened fraction and a nozzle for withdrawing the gas phase. .thirty

Недостатком указанной конструкции вл етс довольно невысока степень . сгущени и отсутствие возможности получени высококонцентрированной твердой фазы в сгущенном потоке.The disadvantage of this design is a rather low degree. thickening and no possibility of obtaining a highly concentrated solid phase in a condensed stream.

Недостаток известного устройства мала эффективность сгущени пульп и суспензий, обусловленна низким качеством продукта, выход щего из нижней части аппарата (сгущенна фракци содержит большое количество влаги).A disadvantage of the known device is the low efficiency of the thickening of the pulps and suspensions, due to the low quality of the product leaving the lower part of the apparatus (the condensed fraction contains a large amount of moisture).

Цель изобретени - повышение эффективности сгущени пульп и суспензий .The purpose of the invention is to increase the efficiency of thickening of pulps and suspensions.

Claims

The goal is achieved by the fact that a hydrocyclone comprising a case, a tangential supply nozzle, nozzles for withdrawing clarified and condensed fractions, a heater located coaxially inside the case, is equipped with a evaporation tube and a nozzle for discharging the gas phase, installed coaxially inside the nozzle for expelled fraction, inside the tube evaporation, the heater is installed with the possibility of axial movement, and a conical socket is attached to the lower part of the gas phase outlet. It is advisable to provide a hydrocyclone with an additional heater placed outside the evaporation tube, while the gas phase outlet and the additional heater are installed with the possibility of axial movement. The drawing shows a General view of the hydrocyclone-evaporator. The hydrocyclone-evaporator consists of a cylindrical body 1 with a lid 2 and a tangential pit connector 3, a cone 4, a drain pipe 5 with a diverging bend 6, equipped with a sleeve 7 and a flare nut 8 for removing the gas nozzle 9 with a conical mouth 10, the main heater 11, additional external heating of bodies 12, evaporation tube 13, retaining pipe 14 for outputting a condensed product equipped with a sleeve 15 and a cap nut 16, which serve as fastening the main heater 11 in the evaporation pipe 13. Moreover, pipe 9 c is conically The barrel 10 and the main heater 11 are mounted on the axis of the apparatus with the possibility of vertical reciprocating movement along it. Hydrocyclone-evaporator works as follows. The pulp, suspension or solution containing crystals is fed through the tangential nozzle 3 into the body of the apparatus 1, where, under the action of centrifugal inertia forces, the solid phase is separated out of the flow, moving towards the periphery of the hydrocyclone and further along the walls of the cone 4 into the evaporation tube 13. The clarified portion of the initial stream with a low content of solid particles is removed from the apparatus through the drain pipe 5 and the discharge elbow 6. A condensed stream through the annular gap formed by the walls. The cone 4 and the conical socket 10 of the gas nozzle 9 enter the evaporation zones, where, by heating this stream with the main heater 11 to the keenes temperature of the liquid phase, its evaporation and, consequently, a considerable increase in the concentration of the solid phase in the condensed product occurs. The vapor formed during evaporation is removed from the apparatus through the gas nozzle 9 and can be directed to condensation. Moreover, the axial movement of this pipe 9 together with the conical socket 10 fixed on it, it is possible to regulate the size of the annular gap between the walls of the cone 4 and the bottom erie; A socket 10 that provides a different concentration of the condensed stream entering the evaporation tube 13. The length of the evaporation section f and the annular gap with in the evaporation tube 13 are selected depending on the power of the main heater 11 and the required degree of condensation (or conical moisture of the condensed product) .. If it is necessary to supply a large amount of thermal energy to the evaporation zone, additional heating of this zone is possible by turning on an additional external heater 12. Condensed to the required amount The centering of the product (if necessary containing the minimum quantity of moisture) is removed from the apparatus through the outlet 14. In the proposed hydrocyclone-evaporator, gas-tube evaporators can be used as the main heater 11, working on combustion products of gaseous or liquid fuels, tubular electric heaters (heating elements) . It is most expedient to use halogen incandescent lamps (infrared emitters) as the main heater, which allow you to create a temperature field that is adjustable in height to the evaporation zone and organize the evaporation process almost without scaling on the walls of the quartz glass heater. Thus, supplying a hydrocyclone with an evaporation tube, coupled with a pipe for discharging the cohesion fraction, with a heater located coaxially in the evaporation pipe with axial movement, a conical socket mounted on the gas outlet pipe, outside the evaporation pipe, will allow condensation in the apparatus is a highly concentrated product with a minimum moisture content, which will lead to a reduction, and in a number of cases, to the complete elimination of expensive General equipment (centrifuges, filters, dryers). By moving the heaters along the axis, it is possible to change the length of the evaporation zone over a wide range and thereby provide the required moisture content of the finished product. The claims of the Hydrocyclone-evaporator containing a hydroponic case, a tangential feed pipe, a pipe, pipes for the withdrawal of the clarified and condensed fraction, a heater,
