Description

one

The invention relates to a technique for the purification of gases when they are in direct contact with a liquid and can be used for the heat and mass exchange treatment of gases in various areas of industry.

The purpose of the invention is to increase the efficiency of gas cleaning and heat and mass transfer processes by improving the interaction of gas with a liquid.

Figure 1 shows the apparatus, a cross section in figure 2 - section A-A in figure 1; in FIG. 3, a device, in the case of an elliptical pipe,} in FIG. 4, a node I in FIG.

The apparatus consists of a housing 1, inside which an pipe 2 is installed along the axis with irrigators 3, made in the form of nozzles or holes, connected to a screw device 4 with blades. The screw device is connected to the housing. The blade can be made multiple. Visors 5 are installed on the surface of the pipe in its lower part, having a rectilinear or curved surface, and fins 6 are installed on the inner surface of the case. In each inter-turn space there are also nozzles 7 and 8 for draining the liquid from the apparatus and draining it.

The gas in each turn of the screw device interacts first.

5 with a liquid in the form of droplets supplied from pipe 2, then a passage through the gap between the housing 1 and the exit edge of the visor 5 forms a gas-liquid foam layer, the ribs 6 of the turbine 10 flow the gas-liquid stream leaving it. The gas after separating from it the moisture in the separator 9 is removed through the pipe 11, and the waste liquid through the pipes 7.

more than with the previously listed states of the liquid phase.

The implementation of a pipe for introducing a liquid with visors installed in its lower part or performing, for example, in the form of an ellipse, makes it possible to increase the velocity of gases when they enter the layer of liquid located in the lower part of the apparatus, which ensures a strong turbulization of gas :, liquid system, fragmentation of bubbles, reduction of their average diameter, i.e. an increase in the contact surface of the phases, as well as the speed of its renewal,. All of this guarantees an increase in the efficiency of x in the apparatus of processes. Moreover, the angle between the visor or the major axis of the ellipse tube and the vertical axis of the apparatus (the angle postponed to the direction of rotation of the gas flow) depends on the specified gas velocity in the zone of formation of the foam structure, 1 the height of the original layer and the desired height of the foam layer. In addition, 5 the ejection of the liquid inlet pipe allows the apparatus to obtain a greater height of the foam layer than when it is cylindrical, which also contributes to an increase in the efficiency of the apparatus as a whole.

By means of the sprinklers 3, the internal cavity of the pipe 2 communicates with the internal cavity of the screw device with blades 4. The surface in the second device is perforated. The apparatus is provided with a separator 9 for trapping moisture from flue gases. There are nozzles 10 and 11 for gas inlet and outlet, which can be drawn in the form of oblique truncated elliptical cones with circular bases to prevent liquid from entering the ducts. The pipe 12 of the input fluid is connected to the pipe 2.

The device works as follows.

The gas enters the apparatus through the nozzle 10 and enters the interturn spaces of the screw device 4, where fluid is supplied via pipe 2 with the sprinklers 3. The constant height of the foam layer in the lower part of each inter-turn space is maintained by means of

When making the blades of the screw device are multiple, while ensuring equal hydraulic resistance of all strokes, the volume is processed. 3, the gases are divided into the number of flows corresponding to the number of screw device visits, and each of them is processed under equal conditions (gas velocities, specific fluid flow rates, high penetration layers and number of active zones), the efficiency of the apparatus is increased compared to single-pass . This is especially noticeable at high gas flow rates through the appliance, since it is known that usually when switching to apparatuses with higher output, while preserving the geometrical similarity to apparatuses with low productivity, their efficiency decreases.

In the case of communication of the internal cavity of the fluid inlet pipe with the internal cavity of the perforated screw device, it becomes possible to create a water curtain in the apparatus to treat the gas flow along its movement, while interacting with which, taking into account the vortex nature of the gas movement, a significant intensification of the processes performed will be achieved in comparison with the device with the continuous screw blade.
