Further, the present invention provides a movable type treatment apparatus that can be used in an area of a degree that it can be installed on even a vehicle by using a simplified treatment process without a large treatment factory plottage. In the conventional sodium dispersing method, a contact probability between a dechlorination reagent and molecules of polychlorinated biphenyl is enhanced through thermal dispersion in order to improve a reaction probability between the dechlorination reagent and the polychlorinated biphenyl molecules by raising temperature.

In addition, above-mentioned waste insulating oil treatment unit can be installed on the vehicle, according to type movably as shown in Figure 2.
The operation of the waste insulating oil treatment unit that the present invention is as above constructed is described below.
With reference to figure 1, when when power subsystem 60 provides power supply, the controller 50 waste insulating oil treatment unit of the present invention of resetting, and receive the Reset Status of waste insulating oil treatment unit from each transmitter.
Under the situation that starts the waste insulating oil treatment unit, the each several part of controller 50 replacement waste insulating oil treatment unit.Controller 50 cuts out the power supply that leads to heating unit 30, stops the operation of driving mechanism 10, inflow pump 80 and overboard pump 70.Controller 50 is determined by liquid level sensor 20 whether waste insulating oils are included in the reaction vessel, and show current state on the supervisory control desk 55 that is connected to controller 50 by the temperature of temperature sensor 40 inspection reaction vessels 15.
Controller 50 control linkages are to the transformer temperature sensor 140 and the transformer liquid level sensor 130 that are arranged in the nozzle 150 in the transformer 160, so that perception is included in the temperature and the liquid level of the waste insulating oil in the transformer, and supervisory control desk 55 is controlled with display result.Under the state that is obstructed to connection electric wire 180 power supplies of the core body 170 that is connected to transformer 160 by controller 50, the waste insulating oil treatment unit is reset fully, so be in the operation stand-by state.
When finishing the inlet of the transformer 160 that the back is installed on nozzle 150 waste insulating oil that wherein contains polychlorobiphenyl in the operation of resetting, transformer liquid level sensor 130 and transformer temperature sensor 140 are immersed in the interior waste insulating oil of transformer 160.When pressing the action button of supervisory control desk 55, controller 50 beginning waste insulating oil treatment unit are handled the operation of the waste insulating oil that contains polychlorobiphenyl.Controller 50 drives inflow pump 80, thereby through nozzle 150 and inflow/outflow flexible pipe 120, the waste insulating oil in the transformer 160 is incorporated in the reaction vessel 15.Make the waste insulating oil of introducing reach the highest liquid level of reaction vessel 15, make the internal upper part of reaction vessel 15 gas of not leaving a blank.
Whether liquid level sensor 20 perception waste insulating oils have reached the highest liquid level of reaction vessel 15.When controller 50 received the highest liquid level signal that is perceived by liquid level sensor 20, controller 50 stopped the operation of inflow pump 80.Agent delivery unit 110 is to the sodium metal of reaction vessel 15 supply predetermined amounts.In order to improve the waste insulating oil temperature in the reaction vessel 15, controller 50 is to heating unit 30 power supplies.Controller 50 controlled temperature transmitters 40 are with the waste insulating oil temperature in the perception reaction vessel continuously 15.When the waste insulating oil temperature is below 100 ℃ the time, controller 50 makes the waste insulating oil each several part temperature in the reaction vessel 15 even with the slow rotating driver 10 of the low speed of the first step.When the waste insulating oil temperature in the reaction vessel 15 became more than 100 ℃, the sodium metal began slowly to disperse in waste insulating oil.
At this moment, between the chlorine atom of the polychlorobiphenyl in waste insulating oil and the sodium atoms metal chemical reaction takes place.Reaction equation is as follows.
Ar.Cl+Na (metal)=Ar+NaCl
(tens PPM) is dispersed in polychlorobiphenyl in the waste insulating oil and the sodium metal moves at random by dissipation of heat on a small quantity, meets each other, becomes harmless NaCl by the chlorine atom of polychlorobiphenyl with reaction decomposes between the sodium atoms metal then.
When the temperature of reaction vessel 15 during 110～145 ℃ of scopes, controller 50 makes specific for some time of driving mechanism 10 high speed rotating, so that the strong eddy current of generation of forced in waste insulating oil, thereby make the sodium metal may run into the probability maximization and the acceleration chemical reaction of polychlorobiphenyl by means of agitating vane that is connected to turning axle and dissipation of heat.Driving mechanism 10 is driven specific for some time.Therefore, turning axle 90 and agitating vane 100 fully react the pcb molecule of waste insulating oil and sodium atoms metal, thereby they are become sodium-chlor, turning axle 90 is connected to driving mechanism rotatably, agitating vane 100 is connected to turning axle and at the waste insulating oil internal rotation, and forms strong eddy current in waste insulating oil.Thus, therefrom eliminate the toxic waste insulating oil of polychlorobiphenyl and become harmless.
Next, controller 50 control overboard pumps 70, thus the high temperature waste insulating oil is expelled to transformer 160, the polychlorobiphenyl in the described high temperature waste insulating oil in the reaction vessel is become harmless by chemical treatment.Here, controller 50 checks by the transformer liquid level sensor 130 that is connected to nozzle 150 whether the waste insulating oil of having discharged reaches the highest liquid level of transformer 160.If waste insulating oil has reached the highest liquid level, then controller 50 stops the operation of overboard pump 70 immediately.
Next, controller 50 is waited for specific for some time, and the heat of waste insulating oil is passed core body 170 to transformer 160, make the polychlorobiphenyl that transformer 160 in, infiltrates the intravital non-impregnated parts of core (container, iron core base part) and flood in the parts (paper or wood type parts) dissolve as waste insulating oil.Here, the chlorine atom of the polychlorobiphenyl in the dissolved parts carries out chemical reaction with the sodium metal that remains in the waste insulating oil, thereby becomes harmless sodium-chlor.
Then, controller 50 applies for some time of electric power Da Teding by connecting electric wire 180 to the core body 170 of transformer 160, and the polychlorobiphenyl of dipping parts has been infiltrated in dissolving more consumingly thus.Preferably, can apply alternating-current to the primary winding of transformer 160, and make secondary coil short circuit, perhaps can apply direct current to primary winding and secondary coil.The polychlorobiphenyl that remains in dipping in inner vessels, iron core and the core body in the transformer 160 and non-impregnated parts is made polychlorobiphenyl and the sodium metal that remains in the waste insulating oil carry out chemical reaction by electrically heated and dissolving, becomes harmless thus.
