In order to test the beneficial effect of wide spectrum induction water treatment device of the present utility model, being connected to Water Treatment in Circulating Cooling System tests, this Water Treatment in Circulating Cooling System dropped into exploitation in 1992, fouling mainly concentrates on process furnace coil pipe, water mixing pipeline, well array and comes oil, crude oil exporting pipeline, water distributing station header and locate for impeller of feeding each water mixing table between the total header of water pump sewage, water mixing or inductor block etc., and fouling mainly shows the following aspects to the influence of production:
(1), the water mixing heater efficiency is low, energy consumption is high, boiler tube is changed frequent.
(2), Water Injection Efficiency descends, the water injection meter well damage, can't measure normally.
(3), pipeline scaling causes oil pipeline to stop up, and causes the well rate of lying high.
(4), pipeline scaling seriously corroded.
For the control fouling, reduce the loss, the gathering system in this Water Treatment in Circulating Cooling System, waterflood system, water mixing system have evenly selected for use wide spectrum induction water treatment device of the present utility model to carry out the antiscaling effect experiment.
The antiscale product is after operation for some time, test section is pulled down the encrustation situation of observing, blank pipeline section, promptly the pipeline section of handling without the antiscale instrument had and adheres to uniform dirt about one deck 0.5mm in the tube wall inboard after 22 days, tube wall inboard after wide spectrum induction water treatment device is handled has only very a spot of dirt with uneven distribution, compare pine of dirty matter with spacer section, a little less than the sticking power, skewness.
Existing corrosion and scaling lacing film is installed behind process furnace and in the water-injection plant, is taken off observation at lacing film after 30 days, the lacing film fouling is obvious, actual test, fouling thickness reaches 1.5mm behind the process furnace, and scaling rate is 18mm/a, fouling thickness reaches 0.8mm behind the water-injection plant low-pressure pump, and scaling rate is 9.6mm/a.
After being installed, wide spectrum induction water treatment device carrying out hanging test once more behind the process furnace He behind the water-injection plant low-pressure pump, take off observation at lacing film after 30 days, fouling is slight on the lacing film, has only a small amount of dirt attached on the lacing film, actual test, lacing film fouling thickness maximum only is 0.1mm behind the process furnace, and dirty matter is loose, water one dashes promptly to fall, sticking power extremely a little less than.Only adhere to one deck oil behind the water-injection plant low-pressure pump on the lacing film, do not see obvious dirty sample.Through lacing film fouling test, antiscaling effect can reach more than 85%.
Before wide spectrum induction water treatment device is installed, this Water Treatment in Circulating Cooling System process furnace is carried out the thermo-efficiency test, thermo-efficiency only is 56%, reach 78% at back 1 month thermal efficiency of heating furnace of the normal operation of wide spectrum induction water treatment device, improved 22 percentage points, the process furnace inlet outlet pressure differential drops to 0.2MPa by original 0.6MPa.Move after four months, the 1.6MPa of water mixing system pressure reduction before by antiscale, be reduced to 0.8Mpa, fail outward in pressing pressure reduction by original 2.42MPa, be reduced to 2.36MPa, the maintenance cycle of strapping table and pump was January twice originally in standing, after wide spectrum induction water treatment device is installed, strapping table normally moves in pump and the station, unusual condition do not occur.
Test shows, use wide spectrum of the present utility model induction water treatment device after antiscaling effect obvious, heat exchange efficiency increases, and has saved the energy.The system maintenance expense reduces, and has reduced labour intensity.
Should be noted that at last that obviously those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these revise and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification.
