Description

I

The invention relates to chemical engineering and can be used in apparatus dp carrying out the process of heat and mass transfer.

It is known to use a bubbling-flow contacting device, which contains a bubbling baton with a conical guide pipe and separate anionic separator, which provides a gas twist. The gas entering through the bubbling drip draws the Q. part of the railway, and the separator passage acquires a rotational motion, the separated snsea liquid flows to the bubbling plate. In a high-speed swirling gas flow, ts-fishing conditions are created for efficient heat and mass transfer processes ij.

Also known is a contact plate containing a separation and ion element consisting of a block of guide plates with hollow and upper rings and a conical guide sleeve iz.

The disadvantage of this contact plate is in its small effectiveness.

in the process of heat and mass transfer: the active interaction of gas with liquid takes place only in the separator and in a small portion of the gas movement at the outlet of the separator. In all other elements of the contact plate, with the direct flow of gas with liquid droplets in the conic. The efficiency of the heat and mass transfer processes is not ensured due to the small relative velocities of the gas and the zhitskost. In addition to TOIX), the device is difficult, there is no possibility of its inspection and repair, it has a large metal content.

The purpose of the invention is to intensify the processes.

This goal is achieved by creating a rotating gas flow, with the conical nozzle attached to the outer edge of the lower ring and provided with a cylindrical side with ribs set at a distance from the housing wall. It is advisable to provide the upper ring with a conical shell attached to it, mounted at a distance from the wall of the housing. The outer ring, the conical guide tube and the conical shell are preferably perforated. FIG. 1 shows a contact plate, a general view in section; and FIG. 2 section A-A in FIG. one; in fig. 3 is a section BB in FIG. 1. The contact plate contains a separating element consisting of a block of guide plates 1, overlapped at the top and bottom with flat rings 2 and 3. A standard flat nozzle 4 is attached to the upper flat perforated ring 2 of the separating element, which is blocked by a lid 5 obsgguzhivan. In addition, a perforated conical shell 6 is attached to the same spear. The outer perimeter of the bottom col 3 is attached — a perforated conical guide nozzle 7 with a flange; its base is equipped with a flange 8 with ribs 9. The cylindrical side 8 is spaced relate to the wall of the apparatus 10, its horizontal edge 11 and the conical shell 12 attached with a neck to the horizontal edge 11 of the housing. Elements 8-1 form a hydraulic shutter. The contact plate works in the following J-IM manner. The rotating gas flow moves progressively from bottom to top, while its upward movement occurs mainly in the near-wall region. When approaching the horizontal edge 11, the gas interacts with the liquid flowing from the conical shell 12, the gas splits jets into droplets, ensuring high speeds of heat and mass transfer processes. Moving further up, the gas interacts with the jets of liquid flowing out of the perforation a conical guide pipe 7, where high speeds of the processes are also achieved. Then, continuing to move upward, the gas enters the block of guide plates 1, where it receives an additional impulse of rotation. Here, too, the gas effectively interacts with the jets of LIQUID flowing from the perforated 8 8 14 adia. At the exit from the separating element, the gas interacts with a liquid that pulls out of the perforated conical shell 6. Next, the gas enters the above plate and the interaction cycle repeats. Thus, the plate provides the interaction of gas with liquid in four zones: when it is drained from the conical shell 12, when the cone 7 goes out of the perforation, in the channels of the block of plates 1 and under the conical shell 6. This ensures the most efficient interaction of the gas with the liquid the form of drops. The present invention intensifies the conducted heat exchangers and heat exchangers, simplifies the design and reduces the metal consumption, improves the conditions of service of the apparatus using the proposed plates: through the lasers, access to them is provided.
