In addition, as shown in fig. 9, the working principle and related control of the special vehicle for oxygen enrichment rescue of the utility model are as follows:
the utility model adopts PSA technology, separates oxygen with oxygen concentration more than or equal to 90% from air, and disperses the oxygen into the oxygen chamber through the dispersion oxygen supply port via pipeline by the controller of the oxygen dispersion system; and detecting the oxygen concentration and the carbon dioxide concentration in the cabin by an oxygen analyzer and a carbon dioxide analyzer at any time. The detected signal is fed back to the dispersion controller, and the dispersion system controller controls the flow of oxygen into the cabin. When the concentration of CO2 in the oxygen cabin exceeds the standard, the dispersion system controller controls the axial flow fan to work for ventilation; so that the oxygen concentration in the oxygen chamber is always maintained between 21% and 26%.
(1) Control of O2 concentration
The oxygen concentration set value of the oxygen analyzer arranged on the special rescue oxygen-enriched vehicle can be adjusted, when the oxygen reaches the set value, the oxygen channel entering the special rescue oxygen-enriched vehicle is automatically cut off, and when the oxygen is lower than the lower limit, the valve is opened to supply the air.
The oxygen amount entering the oxygen-enriched cabin is controlled by a valve which is an electrically-controlled pneumatic angle seat valve, the opening degree of the valve is displayed by a touch display screen in the control cabinet, and the opening degree of the valve can be adjusted by clicking the touch display screen, so that emergency cut-off can be realized.
The oxygen concentration of the oxygen cabin is normal value of 26 percent, the oxygen concentration high alarm value (AH) is 27 percent, the alarm is given out through a buzzer, the interlocking value (SH) is 28 percent, when the oxygen valve reaches the interlocking value, an electric signal is sent to the valve 2 through P L C, the valve 2 is cut off emergently, meanwhile, the waste gas discharging device is opened to discharge air, the oxygen concentration in the oxygen-enriched cabin is reduced, when the oxygen concentration is less than or equal to 25 percent, the valve 2 is opened, and the waste gas discharging device is closed to discharge air.
The oxygen flow is metered by an orifice plate flow meter and displayed on a display screen.
The oxygen concentration of the oxygen-enriched cabin is analyzed by an oxygen analyzer 1, and the oxygen concentration is displayed on a display screen.
(2) CO2 concentration control
The carbon dioxide concentration in the oxygen-enriched chamber is analyzed by the analyzer 2, and the carbon dioxide concentration is displayed on the display screen.
The content of CO2 in a normal atmospheric environment is 350-450 ppm, and the most direct analysis of the content of CO2 in the oxygen-enriched rescue special vehicle is realized by a carbon dioxide analyzer which controls the supplement of fresh air and the emission of waste gas; however, the carbon dioxide analyzer has a large volume, is placed in the oxygen-enriched rescue special vehicle to be slightly in the way of hands and feet, is not attractive, and has high price. Generally, the fresh air volume is calculated by the volume and the rated number of people rescuing the oxygen-enriched special vehicle, so that an axial flow fan with one inlet and one outlet is set to adjust the content of other gases such as CO2 in a room.
The normal value of the carbon dioxide concentration of the oxygen-enriched cabin is 400ppm, the high alarm value (AH) of the carbon dioxide concentration is 500ppm, the alarm is given out through a buzzer, the interlocking value (SH) is 550ppm, when the AIAS102 reaches the interlocking value, an electric signal is sent out through P L C to supply fresh air and exhaust air to the air inlet and exhaust device, the carbon dioxide concentration in the oxygen-enriched cabin is reduced, and when the carbon dioxide concentration is less than or equal to 350ppm, the supply of the fresh air and the exhaust air to the air inlet and exhaust device are closed.
