The petroleum-contaminated soil remediation device is mainly used for quick petroleum-contaminated soil remediation and secondary pollution prevention. The petroleum-contaminated soil remediation device comprises a high-voltage power source, a high-voltage electrostatic soil treatment portion, a high-voltage electrostatic precipitation portion and an insulating portion. The high-voltage electrostatic soil treatment portion comprises a plate electrode with barbs, a medium sleeve and a soil treatment cylindrical electrode portion. The plate electrode with the barbs and a soil treatment cylindrical electrode form counter electrodes. The medium sleeve is arranged on the outside of the soil treatment cylindrical electrode. Medium discharge is realized between the two electrodes after high voltage is added to the electrodes. Petroleum hydrocarbons in petroleum-contaminated soil are dissolved in a medium discharge process, and toxic substances in the soil are heated and gasified in the process. The high-voltage electrostatic precipitation portion is used for preventing the toxic substances from being discharged into air to cause secondary pollution. The petroleum-contaminated soil remediation device is mainly used for remediation for soil polluted by the petroleum production and transportation industry.
Description
Technical field
The utility model belongs to the high-pressure electrostatic application, refers in particular to a kind of oil-polluted soils prosthetic device based on high-pressure electrostatic.
Background technology
In oil exploitation and the transportation, unavoidably can cause the pollution to soil.Contaminated soil will be brought harm to the mankind's health by food chain, and pollute the waste that also causes valuable land resource.Be in recent years study hotspot to the recovery technique of oil-polluted soils, researched and developed several different methods and comprised physics, chemistry, biological method.
The physics restorative procedure can be divided into burning method, electric repairing method, solidify stabilization method, soil replacement method, gaseous phase of soil suction method.Burning method is applicable to the soil remediation of small size.When carrying out the soil burning, diameter of soil pellet there is requirement, and often needs to add the fuel oil auxiliary combustion, may cause secondary pollution.Electricity reparation is that the hot melt glass method is a kind of heat treatment method, by pass into huge current flow in soil, makes the hydrocarbons combustion decomposition in the soil under high temperature action.When soil during by heavy metal and petroleum substance combined pollution, petroleum hydrocarbon is decomposed, and heavy metal then changes into the inert substance of glassy state.This method is applicable among a small circle shallow-layer.Have the advantages that the processing time is short, treatment effect is good, but expense is higher and produce easily secondary pollution.Soil replacement method is for new native all or part of replacement contaminated soil, and the method is applicable to the less situation of contaminated area, but contaminated solution problem fundamentally not.The gaseous phase of soil suction method is by coming the directed flow reparation of reinforced soil air by volatile organic compounds in subterranean layer contaminated unsaturation band extracting gas phase, the organic matter Vapor Entrainment that flowed migrates to ground and is removed, and this method is applicable to the reparation of the unsaturation band contaminated soil of good penetrability and homogeneous.
Chemical repair method can be divided into chemical oxidization method, supercritical fluid method, soil washing method.Chemical oxidization method is to inject in soil or the injection chemical oxidizing agent, utilizes its oxidisability that the petroleum hydrocarbon composition is removed.Supercritical fluid method is a kind of extraction, and it utilizes supercritical fluid to extract petroleum substance in the soil as extractant.The soil washing method comprises cleaning and elution method.It is that the washing agent that utilizes surfactant and water to mix soaks contaminated soil that soil cleans.Soil washing is to utilize leacheate to make pollutant transfer to liquid phase.
Biological method is plant (such as sunflower, cotton, Gao Dancao, the Bermuda grass etc.) repairing polluted soil that utilizes degradation bacteria, is fit to oil polluted environment, and shortcoming is that the time is longer.
Summary of the invention
In order to overcome the deficiency of existing various remedying oil-polluted soils methods, the utility model provides a kind of oil-polluted soils prosthetic device based on high-pressure electrostatic, and this kind is based on the quick remedying oil-polluted soils and avoid the generation of secondary pollution of the oil-polluted soils prosthetic device of plasma.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model device is comprised of high voltage source, high-pressure electrostatic soil treatment part, High Voltage Used for Absorbing Dust part, insulated part, it is characterized in that insulated part is positioned in the middle of high-pressure electrostatic soil treatment part and the High Voltage Used for Absorbing Dust part.
The high-pressure electrostatic soil treatment partly comprises arista electrode plate, dielectric-sleeve, soil treatment columnar electrode part.The arista electrode plate is tubular even distribution cutter shape prickle on it, and blade reduces resistance in order to insert contaminated soil downwards.Arista electrode plate and soil treatment columnar electrode form electrode.Arista electrode is conducive to discharge.After adding high pressure to electrode, this between electrode, produces high voltage electric field.Because soil moisture is uncertain, make inter-electrode short-circuit that the medium socket cylinder is housed outside the soil treatment columnar electrode in order to prevent that soil moisture is excessive.After adding high pressure, form medium discharge at two interpolars.Petroleum hydrocarbon in the oil-polluted soils can decompose in the medium discharge process, and its effect is identical with the electric repairing method that uses now.Equally can make the gasification of being heated of noxious material in a part of contaminated soil with electric repairing method in this course, the vapour of electric repairing method is discharged to causing secondary pollution in the air.For fear of the generation of secondary pollution, the utility model is provided with the High Voltage Used for Absorbing Dust part in order to address this problem.
High Voltage Used for Absorbing Dust partly comprises dust suction tubular electrode, dust suction columnar electrode part.The High Voltage Used for Absorbing Dust part is opposite with high-pressure electrostatic soil treatment partial electrode polarity.In the soil dust particale of gasification part when entering the vacuum part with the opposite electric charge of vacuum part electrode, thereby can be to the motion of antipole plate, thus be attached on the pole plate.High Voltage Used for Absorbing Dust has partly solved the secondary pollution problem.
Insulated part comprises High-Voltage Insulation cylinder and high voltage insulating column.The High-Voltage Insulation cylinder is that isolated dust suction tubular electrode is connected connection with the arista electrode plate.Because the polarity of voltage of the two is opposite.High voltage insulating column is that isolated dust suction columnar electrode is connected connection with the soil treatment columnar electrode.The polarity of voltage of the two is also opposite.
The beneficial effects of the utility model are, fast remedying oil-polluted soils and prevent the generation of secondary pollution.It is mainly used in the reparation of the soil pollution that Petroleum Production and carrier cause.
