Description

The invention relates to devices for mixing turbulent flows of liquids or gases and can be used in various industries of the national economy.

The purpose of the invention is to increase the mixing efficiency in variable operation modes.

FIG. 1 is a schematic diagram of the device in FIG. 2 shows section A-A in FIG. one; in fig. 3 shows an embodiment of a device for turning and longitudinal movement of a disk.

The mixing chamber consists of a housing 1 with an inlet nozzle 2 in which a disk 3 is installed, having evenly spaced trapezoidal windows 4. A high pressure trunk 5 is connected to a manifold 6, which communicates with the nozzles 7. The nozzles 7 are located behind the disk Z. The disk 3 is mounted for rotation and longitudinal movement. The number of nozzles is 7 times the number of windows 4 disk 3..

The device for rotating and longitudinal movement of the disk can be performed as follows.

The inlet 2 in this case has a side entrance. The end of the body is plugged and a device is attached to it, which provides rotation and longitudinal movement of the disk. It consists of a box 8 in which the rod 9 of the disk 3 is installed with the possibility of rotation and longitudinal movement.

The box 8 is closed by a bolt 10. The device has two bushings 11 and 12 and a sealing ring 13; The box 8 has

There is a series of through holes 14, and a rod 9 has a series of transverse holes 15 and a handle 16. To fix the longitudinal position of the disc and the angle of rotation, the device has a finger 17, which is inserted into the hole 14.

The operation of the mixing chamber is as follows.

The drift flows through the nozzle 2 into the mixing zone. In this case, the flow passes through windows 4. In the mixing zone, the distribution of flow parameters is uneven in the circumferential direction. The high-expansion component via line 5 enters the collector 6, from where it passes through the nozzles 7 as a system of transverse jets into the mixing zone.

When changing the mode of operation of the mixing chamber (for example, changing the temperature of the transverse jets or flow, concentration or flow) to intensify the mixing processes, the rod 9 of the disk 3 is longitudinally moved or rotated. In order to fix the angle of rotation of the disk 3 or its longitudinal position, a pin 17 is inserted into the through holes 14 of the box 8 and one of the transverse holes 15 on the rod 9,

With the trapezoidal shape of the windows in the disk compared to the triangular, circular and square, the minimal dynamic unevenness in the mixture flow is realized by organizing a uniform distribution of blockage over the cross section, as well as the maximum relative flow range, within which the mixing efficiency is maximum.
