BACKGROUND OF THE INVENTION The invention relates to disc mass transfer apparatus in relation to processes of rectification, absorption, chemisorption, and other processes carried out with a wide variation in fluid loads.

It is known an overflow device for testing devices, including 1. its coaxially installed connections with located below the bottom ring plates.

A disadvantage of the known overflow is the narrow range of its operation in terms of the throughput of the fluid. The size of the gap chosen by the designer from the conditions created in the overflow of papor fluid cannot provide the overflow ability of the overflow in a wide range of loads.

In order to increase the range of operation of the overflow device at the upper end of the external nozzle, a flexible element, for example, of a terminal-cylindrical form, whose end is located below the upper end of the internal nozzle, is strengthened.

FIG. 1 shows an overflow device with two slits: m, general: view; “And FIG. 2-overflow device with three peaks.

An unreliable device consists of coaxially arranged connections; external-overflow cup I, internal-overflow pipe 2, guide element 3, for example, conical-cylindrical

. The annular guide plates 4 are located under the nozzles of the branch pipes. The location of the guide annular plastip may be in close proximity to the tickle cutoff of the internal nozzle 2 (Fig. I) or at some distance (Fig. 2). Created 1e slots on the chopstick trimming the inner tube is achieved by installing the baffle plate 5. To communicate the cavity formed between the non-return glass 1 and the guiding element 3, the tube 7 is installed above the plate 6 and the steam (gas) under the plate 6 a hole can be made in the overflow

a cup near its attachment to the plate 8.

 the overflow device has two (n more) slots 9 through which the liquid flows out. The design provides for a constant

fluid flow through the bottom gap and

discrete vetulaleppe in the work of other I1, barely 11 under the condition of the location of the slots in the immediate vicinity of each other.

Unreliable device can work and

under conditions when the slots are separated from each other at a certain distance, which makes it possible to create multizone (cascading) irrigation of the inter-disk volume with flat jets. overlap the free section of the coloppa. The principle of operation of the overflow device is as follows. The liquid, overflowing through the upper edge of the overflow cup 1 of the plate, moves along the guiding element 3 and enters the internal nozzle 2, flows out of the annular gap between the lower edge of the nozzle and the reflective disk 5 in the form of a film overlapping the free section of the column. Since the dimensions of I1, the spruce trees do not change, as the liquid flow increases, the level of internal fluid in the internal string 2 increases. Liquid begins to flow into the space between the overflow cup and the internal pipe 2 at the outflow from the second slit formed between the edge of the nozzle and the guides ring plates 4, thereby forming a water seal. If the annular gap is installed in close proximity, they form one film zone of contact of the phases. In an overflow device, when the annular slots are located at a distance from each other, a cascade of two, three, or more film zones overlapping the free section of the column is formed in the interpeller volume. In order to equalize the pressure in the cavity formed between the overflow cup 1 and the guide element 3 with the volume of gas (steam), the tube 6 is mounted on the plate 6. Another design solution for connecting the cavity formed by the overflow cup 1 and the guide element 3 with an inter-lobe volume of iodine by a plate 6, through an opening or a slit located close to the connection of the plate 6 with an irrelevant glass 1. Such a design of the heating device allows full use of the total pressure of the liquid in the overflow and the creation of wet curtains in interdomen prostrapstva. The subject matter of the invention 1. A transfer device for mass exchangers, including coaxially installed connections with disposed ring plates, is designed so that, in order to increase the range of operation of the device, a guide element is fixed on the upper end of the external connection , the lower end of which is located below the upper end of the internal chain. 2. Overflow device according to n. 1, characterized in that the guiding element is made of a copy-cylindrical shape.
