placed in the housing, the inlet pipe of which is in communication with the air intake of the main compressor, and the second outlet pipe is connected at one end to the means, connected to the consumer, and the other through the valve and flow sensor with the first output of the last membrane module (2). The disadvantage of this device is the inability to control the composition of the gas mixture at the outlet to the consumer in a wide range.

Closest to the claimed solution is a breathing simulator containing a gas separation unit with one input for intake of atmospheric air and two outputs; the gas separation unit includes a compressor, adsorption columns, valve systems}, an oxygen storage device, a control and management system, oxygen and temperature sensors; one output of the gas separation unit is connected through a rotameter (gas flow sensor with a regulator) to the consumer's device (breathing tube), etc.), the second to the atmosphere

The principle of the device’s operation is that compressed air is injected into the adsorption columns, where nitrogen is adsorbed from it. When atmospheric air passes through the adsorption columns and the valve system, two flows are formed, one with an increased oxygen concentration (70-98%), and the other with a lower oxygen concentration (14-20%) and increased nitrogen concentration; the first is supplied to the consumer, the latter is discharged into the atmosphere.

The disadvantages of the prototype include the narrow range of adjustment of the composition of the gas mixture at the outlet of the device connected to the consumer’s means, the oxygen in the gas mixture is from 70 to 98%

The task to which the utility model is directed is to expand the range of adjustment of the composition of the gas mixture at the output of the structure, connected to the consumer’s facility.

equipped with two gas pipelines, one of which connects the outputs of the gas separation unit and contains a gas flow mixer with a movable control element connected to the consumer means (breathing tube); another gas pipeline connects the inlet of the gas separation unit with its outlet to the atmosphere and is equipped with a gas flow distributor with a movable control element with an outlet to the atmosphere.

Utility Model Description

The design of the device is shown in Fig. The device includes a gas separation unit 1, comprising a compressor 2, adsorption columns 3, a valve system 4, an oxygen storage 5, a monitoring and control system 6, an oxygen concentration sensor 7 and a temperature sensor 8. The gas separation unit 1 has an input 9 and outputs 10 and 11 Through a flowmeter 12 containing an air flow regulator, the gas line 13 connects the outputs 10 and 11 of the gas separation unit 1 and is equipped with a gas flow mixer 14 with a movable control element. The gas stream mixer 14 through the outlet 15 is connected to the consumer means, for example, with a breathing tube. The gas pipeline 16 connects the inlet 9 of the gas separation unit 1 and its outlet 11, is equipped with a gas flow distributor 17 containing a movable control element and having an outlet to the atmosphere 18. The gas flow distributor 17 is located between the entrance 9 to the gas separation unit 1 and the outlet of the gas pipeline 16.

The movable control element is a truncated cylinder with a control handle.

The valve system is located between the compressor and the adsorption columns, as well as between the adsorption columns and

oxygen storage Elements 13, 14, 16, 17 are made of food-grade plastic

The way the device works

The operation of chefoy is as follows: Atmospheric air (stream A) is sucked through the inlet 9 into the gas separation unit 1 by the compressor 2 included in it. Unit 1, using adsorption columns 3 and a valve system 4, divides the air into two streams, one of which is enriched with oxygen (stream B), the second stream (streams C and D) is depleted of oxygen. It is depleted of oxygen through the valve sysch to outlet 11 into gas pipelines 13 (stream C) and 16 (stream D). The oxygen enriched air enters the oxygen storage 5, then through the valve system 4, the sensoroxygen 7. rotameter 12 - in the gas pipeline 13 (stream B)

Rotameter 12 with a flow regulator can change the flow In and the concentration of oxygen in it. When flow B increases, the oxygen concentration at the outlet 11 of the ayuv separation unit 1 decreases. To further reduce the oxygen concentration at this outlet, part of the oxygen-depleted air (stream D) through the gas line 16 and the gas flow distributor 17 is fed back to the input 9 for nitrogen enrichment Changing the position of the mobile of the replicating element in the gas stream distributor 17, it is possible to reduce the minimum concentration in the oxygen stream from 14 ° to 7%. The gas stream mixer 14 combines the flows B and C in the ratio defined Ohm the position of the movable control element of the mixer 14 and the pressures in the flows B and C. This makes it possible to get at the output of the sling GWA 15. connected to the consumer. oxygen concentration og 7% to 98%. what is he doing
