Description

The invention relates to installations for successively conducting mass transfer tenloi processes, and more specifically to installations for moistening and heating gases. It can be used, for example, as an air conditioner.

A known installation for implementing heat and mass transfer processes, which consists of an air humidifier, a condenser for 100% saturation of air with moisture, a preheater for changing the relative humidity and a cyclone located on the communication line of the condenser and the preheater and intended for separating large ducts and removing them in a humidifier.

The disadvantages of the known construction are the large size and metal intensity of the installation due to the presence of a number of individual devices, as well as the complexity of maintenance and high hydraulic resistance due to the presence of a pipeline system for serial connection of the devices of the installation.

The aim of the invention is to develop a plant for controlling and heating gases, which would not have the disadvantages noted above and justify it; I'm sick performance.

ki, in the quality of which an injection-vortex type mass transfer apparatus was used, an apparatus was sequentially installed to carry out processes of 100% saturation

gas moisture, separating liquid from gas and heating the gas to the required temperature.

Pa figs. 1 shows the scheme of the installation described; in fig. 2 is a section along LL in FIG. one.

The installation consists of a co-compressor /, which is connected by pipe 2 to an injection-vortex type humidifier, having an ivopriyc V, KoirraKTiiyio pipe 4 with slots 5 at the lower end, and a swirler 6, made of radial blades partially overlapping each other, and placed at the top of the contact tube. A baffle plate 7 is placed in the upper part of the housing to separate the liquid droplets.

The pipes 8, 9 are intended for supplying the liquid to the apparatus, and the pipes 10, P. are used for supplying and removing the gas. In order to maintain the required process temperature, the humidifier is equipped with a contact thermometer 12.

Behind the humidifier there is a successively placed aniarate consisting of a cornea 13 with a central tenlo-insulated pipe 14 and a coil 15 wound around it. The inner surface of the housing (see Fig. 2), and its upper end is connected to the pipe 11. The pipe 16 is connected to the pipe 9 by the pipe 20 to the pipe 9. The upper cavity 17 has pipes 2 and 22 for input and output of the refrigerant, respectively. An electric heater 23, for example, of the spiral type, is placed in the central pipe. The installation works as follows. Gas, for example air (solid arrows), from compressor 1 via pipeline 2 flows through pipe 10 into contact pipe 4, carries liquid, such as water (dotted arrows), supplied through pipes 8, 9 and flowing out of slots 5 at the lower end contact pipe. The gas-liquid flow moves up through the pipe and, as it passes through the swirler 6, it begins to rotate. At the exit from the contact tube, under the action of centrifugal force, the phases are separated: the liquid is thrown down to the walls of the casing 3 and flows down, and the moistened gas, expanding at that speed, is removed from the apparatus through the nozzle. The liquid droplets are separated from the outgoing gas by means of the bump stop 7. Through the pipe 19, the air enters the coil 15 and travels downwards through it. When this happens, the vapor of the liquid condenses and the air is 100% saturated with moisture. This is achieved by creating a low temperature in the upper cavity 17 by introducing refrigerant thereto. At the exit of the coil, the gas with condensation resulting from the liquid enters the lower cavity 16 and is twisted by placing the lower end of the coil tangentially to the wall of the housing 13. Under the action of centrifugal force, the liquid drops are pressed to the wall of the housing, the stack is down, and the gas enters central tube 14, the passage through which is heated To the desired temperature using an electric heater 23. The separated liquid from the lower part 16 is again put into the humidifier through the pipe 20 through the nozzle 9. The apparatus placed minutes for the humidifier performs a function of three devices: a capacitor, a cyclone and a heater. Such a structural arrangement significantly increases the compactness of the installation, reduces its metal consumption, reduces the hydraulic resistance and facilitates operation (due to a significant reduction in the piping system, valves and detachable joints). In addition, the use of a humidifier of the injection-vortex type (instead of the bubbling one) allows to increase the capacity of the apparatus and to intensify the process of air humidification. Subject of the invention 1. Installation for carrying out heat and mass transfer processes, comprising a compressor, a gas humidifier, characterized in that, in order to simplify operation, increase the compactness of the installation and combine gas saturation processes with moisture, liquid separation and gas heating, behind the gas humidifier in series an apparatus is installed, comprising a housing divided into two parts by a horizontal partition and provided in the center with a heat-insulated pipe with an electric heater placed in it, for example, of spiral type and an external coil, the lower end of which extends from the horizontal partition tangentially to the inner surface of the apparatus. 2. Installation under item 1, characterized in that, in order to intensify the process of moistening and increase throughput, an injection-vortex type humidifier is used.
