Abstract

The invention relates to devices for producing pulsations in process equipment, can be used in the chemical, petrochemical industry and allows for improved reliability. The pulsator consists of a housing 1 with a partition 3, a distribution disk 4, a rotor 7. A wheel 10 is mounted on the rotor shaft, and a cylindrical shell 15 is attached to the rotor disk. The shell 15, the rotor disk 7 and the wheel 10 are mounted with the possibility of independent rotation from one drive. This design allows to increase the service life of the pulsator and the pulsation supply system and increase the reliability of their operation. 2 Il. // H / 7 I i / l / .10, 21 (O (L with

Description

The invention relates to installations for carrying out heat and mass transfer processes and may find application in the chemical, petrochemical, electrochemical industry for carrying out heat and mass transfer, ion exchange and electrochemical processes.

The purpose of the invention is to increase reliability.

FIG. 1 shows a pulsator, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The pulsator consists of a cylindrical body 1 with a lid 2 and a partition 3, a distribution disk 4 with holes 5 and 6, a rotor in the form of a disk 7 with a guide nozzle 8 attached to it. On the shaft 9 of the rotor there is a wheel 10 of two paired disks 11 and 12 with blades 13 in between, the disk 12 has a central opening 14 connected by means of a guide nozzle 8 with openings of the distribution disk. A cylindrical shell 15 is attached to the rotor disk 7, mounted between the housing 1 and the wheel 10. A hole coaxial with the inlet nozzles 16 and 17 of the pulsator is made in the shell. The shell 15, the rotor disk 7 and the wheel 10 are mounted for independent rotation from a single drive. In this case, for this purpose, a planetary mechanism 18 is mounted on the rotor shaft 9, the satellites 19 of the short are rigidly connected to the shell 15 and the disk 7. The nozzles 20 and 21 are input.

Pulsator works as follows.

When the pulsator is turned on, the rotor shaft and the wheel 10 mounted on it rotate at the speed required to pump a certain amount of fluid. The planetary mechanism allows

rotate disc 7 and shell 15 at a frequency optimal for intensifying a particular process.

This design of the pulsator makes it possible in the pipelines, the pipes of the pulsator, to exclude the reverse movement of the fluid, which can cause a significant overpressure in them, leading to fluctuations in the pipelines, depressurization of flange connections and destruction of the welded grooves. Elimination of these phenomena allows to increase the service life of the pulsator and the pulsation supply system and, accordingly, increase the reliability of their operation. In addition, with this design, the hydraulic resistance of the pulsation supply system is less, less volume loss, less equipment.
