Effect is bad.It needs frequently to enter when live gasworker adjusts corrosion inhibiter adding amount to relate to sulphur region, there are certain safety winds
Danger.Long-term adjustment corrosion inhibiter may adjust personnel to corrosion inhibiter and bring occupational health risk.Therefore, it is necessary to invent a kind of inhibition
Agent flux control device, to solve appeal technical problem.
Utility model content
The utility model be intended to adjust for corrosion inhibiter adding amount in current production process not in time, inaccuracy and can not carry out remote
Journey adjust the problem of, a kind of corrosion inhibiter volume control device is provided, with realize using the prior art control corrosion inhibiter adding amount with
Gas output per well carry out real-time change, or corrosion inhibiter adding amount is remotely controlled by host computer related interfaces.
To achieve the goals above, the utility model is achieved through the following technical solutions: a kind of inhibition agent flux
Control device, it is characterised in that: including obtain individual well produce air-flow meter, dispenser pump correlated condition, dosing pump, stroke adjuster,
SCADA system, man-machine interface, servo motor and PLC system, the acquisition individual well produce air-flow meter, dispenser pump correlated condition, add
Teat pipette, stroke adjuster, SCADA system, man-machine interface and servo motor carry out telecommunications connection, the PLC system with PLC system
System is made of power module, CPU module, communication module, I/O module and expansion module.
Further, the stroke of the dosing pump can change according to PLC system output signal.
Further, the individual well produces air-flow meter and dispenser pump correlated condition exports analog signal, and incoming PLC in real time
System.
Further, the stroke adjuster carries out the stroke of dosing pump according to the output analog signal of PLC system real
When adjust.
Further, the PLC system will control electric signal by PID control and be sent to stroke adjuster, and stroke is adjusted
The stroke of dosing pump is adjusted in device, to change the filling flow of dosing pump.
Further, the flow of the dosing pump can carry out remote manual adjusting.
A kind of corrosion inhibiter volume control device of the utility model realizes the real-time adjusting tracking prison of corrosion inhibiter filling
Control, avoids manual operation corrosion inhibiter adding amount and actual requirement (corresponding practical acid gas amount) temporal disconnection.Completely
Automation is realized, cost of labor is saved, to realize that unattended station provides technical support.It reduces because of corrosion inhibiter adding amount mistake
The waste of corrosion inhibiter caused by amount, to reduce corrosion inhibiter use cost.Anti-corrosion is imitated caused by reducing because of corrosion inhibiter adding amount deficiency
Fruit is bad.The personnel of avoiding, which frequently enter, relates to sulphur execute-in-place bring security risk.Operator is avoided often in contact with slow
Lose agent bring occupational health risk.
