Abstract

The invention relates to pulsators for pulsating movement of a solid phase on contact plates and provides an increase in the efficiency of the process by generating asymmetric pressure pulses in a pulsation nozzle. The pulsator contains a cylindrical body with nozzles 2, 3 pulsations, a nozzle 5 for etching and a nozzle 6 for feeding. On the inner surface of the housing between the pulsation nozzles 3 and the bleed nozzle 5, a groove 7 of variable cross section is made. The axis of symmetry of the groove 7 is in the cavity of the axes of the nozzles 2, 5, 3, 6. Coaxially with the supply nozzle 6 on the opposite side of the body is placed the nozzle 5 of bleeding, coaxially with the nozzle 3 pulsations on the opposite side of the body nozzle nozzles 2 are located. To obtain an asymmetrical pressure pulse in the pulsation nozzle, the angle between the pulsation nozzle 2 and the bleed nozzle 5 must be less than 90 °. A buffer tank 4 is connected to the nozzle 3 of the pulsation. Inside, a rotor with a partition 9 is located coaxially with the housing, dividing the rotor cavity into two chambers 10, 11, and a slot perpendicular to the cylinder is made on the cylindrical surface of the rotor. 3 il.

The invention relates to apparatus designed to intensify the extraction processes in solid-liquid systems, namely, devices designed to carry out a pulsating movement of the solid phase on the contact mass transfer plates of the apparatus.

The aim of the invention is to increase the efficiency of the extraction process by

rotation of the rotor 8, the partition 9 occupies a position in which the liquid from the pulsation nozzle 2 begins to move into the bleed nozzle 5 and then into the suction line of the constant pressure drop source. At the same time, the value of a positive pulse begins to decrease. At the same time, the liquid from the supply nozzle 6 and the buffer tank 4 flows through the groove 7 of the variable cross section of the asymmetrical pulses 10 and enters the nozzle 5. At the same time

the suction of fluid from the nozzle 2 is slowed down, the pressure pulse is extended, and its duration is proportional to the rotation of the rotor 8 with the partition 9 at an angle (180

pressure.

gate of the septum. The duration of the positive impulse contains a cylindrical core-pulse determined by the time of rotation of the peps 1 with the nozzle 2 pulsations, the connecting partition 9 through an angle of 180 °.

Node with a device, a nozzle 3 bullets. Simultaneously with the occurrence of a strip, connected to the buffer capacity 4, a vital impulse in the pulsating nozzle 5 of the bleed and a nozzle 6 20 of the cockpit 2, a negative impulse is formed. A pressure pulse is transmitted to the pulp. 1cation pipe 3 and associated with it

Between the pulsation nozzle 3, the buffer tank 4. connected to the buffer tank and the bleed nozzle 5, a groove 7 of variable cross section is made.

The symmetry axis of the groove 7 is in the plane of the axes of the nozzles 2, 3, 5 and 6.

Nozzles are located as follows. Coaxially with the supply nozzle 6 on the opposite side of the body, a jQ pulse is placed. Upon further rotation, the nozzle 5 is vented and the pressure pulsation coaxially repeats,

a pulsation nozzle 3 on the opposite side; When an asymmetrical body side is generated — a nozzle 2 pulsations in an extractor connected to the pulsation, a sator, the solid moves to get a pulsation nozzle and the phase moves over the contact

Ke 2, connected to the apparatus, of the impulse 35 with devices along trajectories similar to the pressure of asymmetrical form, the angle between the pulse, the pulsation nozzle 2 and the bleed nozzle 5 should be less than 90 °. At an angle of more than 90 ° between the pulsation nozzle 2 and the bleed nozzle 5, the water level in the apparatus constantly rises and the apparatus overflows. Inside the coaxial with the housing 1 there is a rotor 8 with a partition 9, placed along the generator cylinder

Further movement of the rotor 8 leads to the message of the supply nozzle 6 with the pulsation nozzle 3 associated with the buffer tank 4, the supply of fluid in which is necessary to ensure continuous operation of the constant pressure source while creating a positive 40
