Description

The technical field to which the utility model belongs.

The utility model relates to gas separators of air for oxygen and hypoxic components using pressure swing adsorption technology, including columns with adsorbent compressed by spring-loaded frames; manifolds with air channels, providing pneumatic connection of the distribution mechanism with the columns and columns with nozzles, covering the column block from above and below; a distribution mechanism that provides compressed air supply to the columns and purging of the columns; disc with nozzles for oxygen outlet into the upper manifold cover; distributor housing with thread for hypoxia outlet; cover of the upper manifold with threads for connections for compressed air supply and oxygen outlet.

The device is designed to obtain oxygen (for medical, fish farming, etc.) on one side (in the oxygen concentrator mode, hypoxia, air with a reduced oxygen content is a by-product) and to obtain air with a reduced oxygen content (for high-altitude training athletes) on the other (in this case, oxygen is a by-product).

State of the art.

A gas separator manufactured by SeQual Technologies (model SeQual ATF-15) is known in the art.

See internet source:

This level of technology is the closest in technical essence to the claimed utility model and is taken as a prototype to the proposed utility model.

This gas separator has a round shape.

The main disadvantages of this device:

- the round shape does not allow the most efficient use of the body volume in which the gas separator will be installed;

- round pipes do not allow achieving the most compact dimensions of the device, since there is a lot of empty space between the round pipes.

In addition, this device has the following disadvantages:

- impossibility of repair,

- the complexity of the assembly.

Thus, the task is to create the most compact and lightweight gas separator for a mobile oxygen concentrator / hypoxicator, easy to assemble and repair.

Disclosure of the utility model.

Based on this original observation, the present utility model mainly aims to propose a gas separator of air for oxygen and hypoxic components using the pressure swing adsorption technology, including columns with adsorbent compressed by spring-loaded frames; manifolds with air channels, providing pneumatic connection of the distribution mechanism with the columns and columns with nozzles, covering the column block from above and below; a distribution mechanism that provides compressed air supply to the columns and purging of the columns; disc with nozzles for oxygen outlet into the upper manifold cover; distributor housing with thread for hypoxia outlet; cover of the upper manifold with threads for fittings for supplying compressed air and oxygen outlet, which makes it possible to smooth out at least one of the above disadvantages, namely: the possibility of creating the most compact and lightweight gas separator for a mobile oxygen concentrator / hypoxicator, which is the delivered technical the task of the utility model.

To achieve this goal, the columns are made in the form of a single block with internal baffles dividing the columns.

Thanks to this advantageous characteristic, it becomes possible to increase the efficiency of using the internal volume, at the same time to simplify the assembly of the device and provide the possibility of simple repair.

There are variants of the utility model in which the column block is made extruded.

According to figures 1-6, the gas separator of air for oxygen and hypoxic components using the pressure swing adsorption technology contains a block of 12 columns (1) filled with zeolite (2) compressed by spring-loaded clamping frames (3); manifolds (4) with air channels, providing pneumatic connection of the distribution mechanism with the columns and columns with nozzles, covering the column block from above and below and fastened with screws through threaded connections; a distributor mechanism (5), which provides compressed air supply to the columns and purging of the columns; disc with nozzles for oxygen outlet into the lower manifold cover (6); distribution mechanism housing (7) with thread for hypoxia outlet; cover of the upper manifold (8) with threads for connections for compressed air supply and oxygen outlet.

The columns are made in the form of a single block (9) with internal partitions (10) dividing the columns. Advantageously, the unitary block has a rectangular cross-section and is divided by internal baffles that are perpendicular to each other.

The collectors are attached to the columns through threaded connections. Tightness is ensured by the seal (11). See figure 6.

Implementation of the utility model.

The gas air separator is used in a standard manner.

Industrial applicability.

The gas air separator can be carried out by a specialist in practice and, when implemented, ensures the implementation of the declared purpose. The possibility of implementation by a specialist in practice follows from the fact that for each feature included in the formula of a utility model based on the description, a material equivalent is known, which allows us to conclude that the criterion "industrial applicability" for the utility model and the criterion "completeness of disclosure" for the utility model ...

In accordance with the proposed utility model, the applicant made a prototype of the proposed gas air separator.

Experimental operation of the proposed gas air separator has shown that the proposed solution allows:

1) Achieve the most efficient use of the usable volume due to the rectangular shape of the one-piece structure of the column block. The filling factor of this block of columns with zeolite (the ratio of the volume of the zeolite to be poured to the volume of a parallelepiped or cylinder in which this block can be placed) is 64%, and for the prototype it is 44%. This advantage provides the compact size and low weight of the gas separation unit.

2) Simple technology for assembling the gas separation unit. In the prototype, twelve columns are glued into the collectors, because of this, the assembly process requires low-tech operations of applying glue, installing each column in the collector and waiting for solidification after gluing. In the proposed utility model, the columns are a single block, to which each collector is attached at seven points. Tightness is ensured by a rubber seal.

3) Reducing the cost of production by reducing the amount of material used, since a single block of columns has common column walls.

4) The absence of gluing makes the column collapsible, which allows changing the zeolite when it is worn out. The basic model is non-separable and cannot be repaired if it is worn out or damaged (as a result of water ingress, for example).

The geometric dimensions of a particular model depend on the required performance.
