Reactor oxygen content detector
Brief description:
Customized pretreatment of reactor oxygen content detector: acid-base neutralization, organic matter removal, water removal, drying, voltage stabilization, constant current, etc.
The nitrogen filling protection of the reactor oxygen content detector is roughly the same as that of the centrifuge; especially during the hydrogenation process, vacuuming and nitrogen replacement must be strictly repeated to fully ensure that the reactor is in an anaerobic state, and the oxygen content must be controlled within 1%VOL; higher requirements are placed on the service life, accuracy, error and response time of the sensor.
Since it is impossible to ensure that the nitrogen meets the qualified supply input, the traditional continuous nitrogen replacement also has the possibility of explosion.
In response to the above situation, our company adopts pre-stage sampling pretreatment + on-site numerical display + automatic nitrogen filling, and can also be transmitted to DCS/GDS through 4-20mA signal according to supporting needs to achieve overall automatic chain control.
Product features of reactor oxygen content detector manufacturer:
1. Customized pretreatment: acid-base neutralization, organic matter removal, water removal, drying, voltage stabilization, constant current, etc. of sample gas.
2. Safety: The oxygen concentration value exceeds the first-level preset alarm value, Automatically turn on the electromagnetic adjustment nitrogen replacement until the value drops to a safe range.
3. Nitrogen flow control: Equipped with a nitrogen control box, it automatically cuts off the large flow when the oxygen concentration value is within the safe range to achieve continuous supply of small flow, meeting the micro-positive pressure in the kettle.
4. Applicable explosion-proof area: intrinsically safe explosion-proof composite instrument, meeting the demanding use area.
5. Signal acquisition: 16-bit ADC digital-to-analog conversion, meeting the trace oxygen data acquisition, with higher accuracy.
6. Module platform: The pre-processing level and function can be freely adjusted according to the actual use situation, with a wider range of adaptability, etc.
