The filter installation hole, the air primary filter is installed in the air primary filter installation hole; however, it does not solve the phenomenon of linkage of several devices, so a connection system for the oxygen expander heat exchanger is needed.

Utility model content

The technical problem to be solved by the utility model is aimed at the phenomenon that the structure between the existing oxygen generator expander and the heat exchanger is complex and cannot realize the linkage of several devices.

The technical solution adopted for solving the problems of the utility model is: a radiator marshalling system for an oxygen generator expander, including an oxygen generator unit, a radiator, a water inlet pipe valve, an air outlet pipe valve, a sensor group and a controller. A radiator is arranged on the outside of the oxygen generator, the upper part of the oxygen generator is connected to the water inlet pipe through the water inlet valve, the lower part of the oxygen generator is connected to the outlet pipe through the outlet valve, and the sensor group is arranged on the oxygen generator. The sensor group, the water inlet pipe valve and the air outlet pipe valve are respectively interconnected with the controller signal.

The oxygen generator set includes two oxygen generators, and the two oxygen generators form an angle α.

The sensor group includes temperature sensors and pressure sensors.

The controller is PLC.

Both the water inlet pipe valve and the air outlet pipe valve are electronic valves.

The α included angle is 60-120°.

In the utility model, two oxygen generators are placed at an angle of 60-120°, and a radiator is arranged on the inside of the angle, so that it can provide cooling service for two oxygen generators at the same time, and can also provide heat dissipation service for one of them. Provide heat dissipation service, which is controlled by PLC, so that it can not run when heat dissipation is not needed, and avoid energy loss caused by idling; since two oxygen generators are one oxygen generator unit, they can share a total The water inlet pipe and the total air outlet pipe, so that it can be diverted to the two oxygen generators after passing through the three-way valve. The electronic valve is set on the branch pipe, which makes it easy to control the opening and closing through the PLC, and with the cooperation of the sensor, it can realize the opening and closing of the valve independently and realize the intelligent control function; the temperature change can be monitored through the temperature sensor. When it is high, it will automatically trigger the radiator to dissipate heat. When the temperature is within the appropriate range, it will stop running; when an oxygen generator fails, its temperature is abnormal and the pressure loss is serious or the pressure is too high, then the PLC will close the branch pipe. The electronic valve makes the oxygen generator stop running, and then the PLC sends out an alarm to remind the operation and maintenance personnel to come for maintenance, so as to ensure the stability and safety of the operation. This connection system can greatly improve the stability of the oxygen generator system , to avoid a phenomenon that a fault occurs that stops.

The utility model adopts a marshalling method in which two oxygen generators form a group, so that they can serve as backup devices for each other, and can run at the same time or only one can be turned on, so that when the marshalling works, even if one group fails, it can be stable. It can not only avoid the waste of resources caused by one oxygen generator matching one radiator, but also ensure the smooth operation of the work; and the use of an independent control system enables it to operate independently, thereby ensuring stable operation and not only realizing energy saving Emission reduction, but also to ensure smooth operation and maximize efficiency, it is worthy of promotion and application.
