| Oil pipeline fouling often give oilfield water injection systems, plumbing pipes and crude oil dehydration brings many technical and economic problems due to chemical cleaning methods will not only cause environmental pollution, but also greatly reduce the operating ef Ticiency of the equipment, additional equipment workload. Using electromagnetic technology is the future trend-fouling Anti-fouling, and it has the advantage of green, simple operation and low price has been well received by the industry.Electromagnetic Anti-fouling device designed by this paper?the technology is produced by the C8051F020 microcontroller square wave signal frequency can be changed, then the square-wave signal is output to the control chip HIP408 I H-bridge driver circuit, output circuit after driving large current variable frequency square wave signal to the coil, for oilfield water injection pipeline and crude oil dehydration system fluid in a conduit tor processing, by the action of electromagnetic waves on the water and ion fluid, changing ionic binding mode and then change the scale of precipitation way to reach-fouling purposes.Anti-fouling developed utilizing electromagnetic means, calcium carbonate(Ca CC>3) for the study, conducted the experimental study of static and dynamic experimental studies measured the calcium carbonate(Ca C03) changes in the solution calcium levels, by comparison test was out: calcium carbonate(Ca COJ changes in the solution of calcium content and fouling can occur under the influence of external electromagnetic-fouling device.In summary, the electromagnetic-fouling device having a cleaning?scaling function, the frequency components?water effect and electromagnetic waves have a great relationship, so, in different environments, can be adjusted according to the specific circumstances in order to for best results, along with increasingly stringent and increasingly scarce water resources, electromagnetic-fouling technology w川 be more widely appreciated, this system has important significance for environmental protection. |
