Description

The recycling system of wasted transformer

The present invention relates to a waste power equipment recycling processing system, and more particularly, polychlorinated biphenyls (PCBs), which are highly insulating oils contaminated at about 50,000 ppm contained in waste power equipment during the disposal of waste power equipment such as waste transformers. The present invention relates to a waste power equipment recycling processing system capable of extracting and refining with a low concentration of insulating oil of less than 2ppm through a chemical treatment device and simultaneously recycling non-ferrous metals contained in waste power equipment.

As is well known, a representative example of the waste power equipment is a waste transformer.

The waste transformer is composed of a cylinder (scrap metal), insulators, PCBs (insulated oil), insulating paper, core (silicon steel), coils (copper), etc. in Korea, it is known that about 100,000 transformer transformers are generated annually. have.

Therefore, since the waste transformer includes a large amount of resources that can be recycled in the waste disposal process, the conventional non-ferrous metals have been recycled in the process of discarding the waste transformer.

However, most domestic companies that collect and dispose of waste transformers contain waste oils containing less than 2 ppm of contaminated PCBs contained in the waste transformers. In addition, some companies were in the process of collecting or cleaning the waste transformer polluted with more than 2ppm of insulating oil.

In particular, a method of disposing waste power equipment such as a conventional waste transformer is to manually open a top plate of a waste transformer in a roadbed or a workplace, tilt the waste transformer to remove contaminated insulating oil remaining in the waste transformer, and directly After separating the components, cutting was performed directly using a cutting machine or the like.

As a result, the harmful gas generated inside the waste transformer harms the worker's health, and the work is mainly performed on the road, causing insulation oil to penetrate the soil, causing environmental pollution.

Furthermore, PCBs (Polychlorinated biphenyl) contained in the pulmonary transformer are very stable organic compounds produced by the reaction of chlorine and biphenyl. They are not soluble in water but soluble in oil or organic solvents. It has been widely used in transformers and electrical insulators because of its high heat preservation. These PCBs are one of Persistent Organic Pollutants that are highly toxic and slow to degrade and remain in the ecosystem for a long time. Has been known to cause strong carcinogenic effects and birth defects. Especially, it has been found that it is not absorbed into the body and harms the human body by contact alone. It is not happening.

However, in the case of the transformer produced using the insulating oil containing PCBs, when the lifetime of the product has to be disposed of, the disposal of the PCB oil contained in the waste transformer is severely contaminated and disposed of when it is more than 2 ppm. Since the technology of refining and recycling it was not introduced in the process, as a result of simply washing or incineration, not only resource waste but also environmental problems have emerged.

That is, in the past, domestic companies have used a high temperature incineration and melt treatment method, a high temperature pyrolysis technique, or a dechlorination method sodium as a method of treating contaminated PCB containing insulating oil, but the high temperature incineration and melting The treatment method has a large amount of dioxin generation and pollution concentration, so there is much room for civil complaints. The high-temperature pyrolysis technology is suitable for processing solid PCBs, but it takes a long time and is limited by space. Among the dechlorination methods, the sodium method is a method developed and applied in Europe, and there is a risk of explosion, and it is known that there is an actual explosion in foreign countries.

Therefore, there is a need for the development of a new system that can improve the problems of refining system and waste disposal process to recycle the insulating oil containing PCBs (PCBs).

Therefore, the present invention has been researched and developed as the necessity of developing a new recycling treatment system for waste power equipment such as the above-described waste transformer, the object of the present invention is more than 2ppm using a reaction catalyst through a chemical treatment device By refining and refining the contaminated insulating oil to less than 2ppm, it contributes to industrial development by recycling the insulating oil and recycles waste power equipment recycling system to solve various problems such as environmental pollution caused by the disposal of waste power equipment.

In addition, Figure 10 is a view showing a state in which the consignment treatment by separating and storing by the solid type after cleaning and separating the waste transformer according to the present invention.

As shown in Figure 1 and 2, the waste power equipment recycling treatment system according to the present invention is a polychlorinated salt which is a high concentration of insulating oil contaminated at about 50,000 ppm contained in the waste power equipment during the disposal of waste power equipment such as a waste transformer It is characterized by extracting phenyls (PCBs) through a chemical treatment device and reprocessing the non-ferrous metals contained in the waste power equipment at the same time.

To this end, the present invention can be largely divided into a treatment preparation step (S1), a cleaning and drying step (S2), a centrifugation step (S3), a chemical treatment step (S4), and an oil vapor treatment step (S5).

Here, as shown in Figures 2 and 3, the treatment preparation step (S1) corresponds to the preparation process until the waste power equipment is collected and transported before disassembling after storage and storage in the factory equipped with a treatment facility.

That is, it signed a supply and consignment contract with the Korea Electric Power Corporation, the Korea Railroad Authority, the Ministry of National Defense, and KT, a representative company that generates waste power equipment such as the waste transformer 100, and received it through a designated waste collection transport company. It is safely received at the factory.

At this time, the waste transformer 100 is dismounted from the designated waste collection and transport vehicle 110 by using the forklift 12 and the cargo crane, and the unloaded waste transformer 100 is loaded on a work bench.

Then, the insulator of the waste transformer 100 loaded on the work table is cut using an electric cut grinder (Electric Hand Grinder) for 1/3 or more, and the cut insulator moves to the dismantling workshop of the waste transformer 100 to remove the nonferrous metal of the insulator. Separate and separate insulators and non-ferrous metals are transferred to the warehouse waiting room.

In addition, the waste transformer cut out the insulator 100 is loaded on the work pallet 130 of steel material for safe transport and loading, and in this state the work pallet 130 is loaded into the storage warehouse 140 by the forklift 120. By doing so, the preparation for the cleaning and drying process (S2) is completed.

At this time, the size of the working pallet 130 is preferably 1,500 mm (W) x 5,000 mm (L) x 1,500 mm (H), the storage warehouse 140 can support the load of the storage transformer (100) storage capacity It is preferable to install a floor (0.7m concrete), waterproof packaging to prevent contaminants from penetrating, and to install a concrete block 300mm (H) around the storage warehouse 140 for the safety of secondary leakage.

As such, when the treatment preparation step S1 is completed, as illustrated in FIGS. 4 to 6, the waste transformer 100 is decomposed, washed, and dried to perform the washing and drying step S2.

Cleaning and drying process (S2) according to the present invention has the advantage of implementing a complete environmental pollution prevention process as a batch process in the washing machine 300 as shown in FIG.

That is, when using the dryer 300, by meeting the standards for preventing the outflow of PCBs (PCBs) vapor prescribed in the enforcement regulations of the persistent organic pollutant management law, it has the advantage that can comply with the related laws and regulations.

At this time, the washing machine 300 is a facility for using the waste transformer 100 to completely clean, dry the insulating oil that is moved and adsorbed in a safely closed space.

That is, as shown in the figure, the drier 300 has a cylindrical body 301 having a volume of about 22.6 m 3 to accommodate the rotary clamp frame 206, which will be described later, on the tracked vehicle 160. In addition, a heater 302 for vacuum drying and a nozzle device 303 connected to the automatic air ball valve 306 and the ball valve 307 are provided therein, and the body 301 is provided therein for high-speed injection of the cleaning liquid. The left and right sides of the side is provided with an opening and closing sealing cover 304, the sealing cover 304 is provided with a side window 305 for the operator to look inside the dryer 300, the upper safety hole cap ( 308) is provided.

The washing machine 300 as described above uses a special apparatus because the human hand is not touched and everything is automated and sealed so that pollutants do not leak to the atmosphere and the outside, and the oil in the heat sink of the waste power equipment does not generally fall out. The oil can be completely removed by cutting, and the oil can be completely cleaned by removing the oil from the waste power equipment using a special solvent.

In addition, a dry state can be made by drying the waste power device cleaned in the washing machine 300 at 60 ℃ and suctioned by a vacuum pump.

Cleaning and drying process (S2) according to the present invention using a drier 300 having the above characteristics is first subjected to a pretreatment process.

That is, in order to separate the insulating oil inside the waste transformer 100 with the washing machine 300 and then to clean and dry, the rotary clamp 200 may be fixed by tilting the waste transformer 100.

As shown in Figure 5, the rotary clamp 200 is a clamp that can be fixed and tilted the transformer body of the various specifications specially manufactured, and secures the body of the closed transformer 100 automatically in a safely closed space Lifting the waste transformer (100), it is a facility for pouring the insulating oil to the dryer 300 by rotating up, down, it is a facility capable of adjusting the angle of the waste transformer (100) during cleaning.

That is, the above-described rotary clamp 200 is prepared on the tracked vehicle 160 that is a workbench for pretreatment, and the waste transformer 100 discharged from the storage warehouse 140 is positioned using the hoist crane 150.

Then, after loosening the coupling bolts of the upper cap 101 of the closed transformer 100 and releasing the clip, the closed transformer 100 is placed at the center of the rotary clamp 200 and adjusted by the adjustment lever 203. (However, it can be omitted if the dimension is within the 30mm deviation range.)

Then, the closed transformer cap 101 is connected to the separator lever 202 of the rotary clamp 200 by three to four lines using a dedicated rope 201, and the vertical center portion of the closed transformer 100 and the rotary clamp adjustment lever ( 203) The center is fixed using the chain clamp 204. (At this time, the rotation angle of the rotary clamp 200 is preferably maintained at 0 degrees.)

When the pretreatment is finished, the lung transformer 100 is moved and fixed in the drier 300.

The clamped rotary clamp 200 is moved into the dryer 300 using the tracked vehicle 160.

Then, the power transmission shaft 205 attached to the rotary clamp 200 is connected to the washing machine 300, and the lever for separating the closed transformer 100 cap is also connected to the washing machine 300.

The rotary clamp frame 206 is fixed to the inside of the washing machine 300 with a fixing pin, and then closed by closing both airtight covers 304 of the washing machine 300.

As such, when the closed transformer 100 is moved and fixed through the rotary clamp 200 inside the washing machine 300, a process of detaching insulating oil is performed.

That is, the rotary clamp 200 is tilted 110 degrees to completely follow the insulating oil contained in the closed transformer 100.

Thus separated 2ppm or more insulating oil is integrated in one place as shown in Figure 7 is transported and stored in the storage tank 400 or more by 2ppm or more along the transfer pump 401 through a filtration filter.

The storage tank 400 is an atmospheric storage tank for neutralizing insulating oil containing PCBs of 2ppm or more through a chemical treatment process (S4), and the storage tank 400 is installed with an oil gauge to check the amount of insulating oil with the naked eye. It is supposed to be.

Then, when the insulating oil is separated by the automatic operation of the panel in the sealed state inside the washing machine 300, the buzzer rings to signal the worker that the cleaning step has been reached.

When the worker operates the work button after checking the inside using the side window 305, the cleaning process is in progress.

The cleaning process of the present invention is characterized by emulsification by adjusting the contact angle and the wetting agent through a cleaning liquid (e.g., Junsu Co., Ltd., a product of Hansoo, using the trade name HansuClean CR-150, which is a non-flammable water-soluble liquid). Or a technique in which a cleaning liquid that is not fused captures and detaches insulating oil.

At this time, the components of the cleaning liquid used in the present invention are as shown in Table 1 below.

 Table 1

Composition / information on ingredients Name ingredient CAS number Content (%)  HANSUCLEAN CR-150 (brand name)  2-Butoxyethanol D-Limonens Dimethyl Glutarate Polyethylene glycol fatty acid ester Others  111-76-2 5989-27-5 001119-40-0 9005-65-5-  20 25 1.5-2.0 5.0 7.0 5- 7 rest

The cleaning solution requires less contact angle than insulating oil, and the wetting agent is required to be more flexible. In the present invention, this is achieved by adjusting hydrophilic hydrophilic balance (HLB).

Herein, the washing process applied to the present invention will be described in more detail. First, after rotating the rotary clamp 200 which fixes the waste transformer 100 to completely separate and transport the insulating oil, the waste transformer 100 is normally turned upward. In the posture, the washing solution is sprayed into the waste transformer 100.

At this time, the cleaning liquid is supplied through the feed pump 503 from the cleaning liquid tank 502 connected to the nozzle device 303 provided in the dryer 300.

In addition, the cleaning solution is injected into the waste transformer 100 and at the same time to vibrate the vibration motor 309 having a vibration transmission rod located inside the washing machine 300 on the silicon steel plate to generate a vibration of about 3,600 cycles / min.

In this case, the capillary phenomenon inevitably occurs at the contact portion of the silicon steel sheet and the inner part of the waste transformer 100 is activated, and the gap between the contacted portions is widened or narrowed due to vibration, and the capillary tube occurs. The amount of liquid is increased or decreased by the phenomenon. That is, the pumping action is generated.

Due to the pumping action, the cleaning liquid is exchanged with the insulating oil, so that the insulating oil is collected and detached from the cleaning liquid, and only the cleaning liquid film is left on the inner and outer surfaces of the waste transformer 100 and the inner member so that the cleaning operation is performed.

Of course, the cleaning solution is also strongly sprayed on the lid and bush of the separate transformer 100, which is separately cleaned.

In particular, after the cleaning operation for 5 to 6 minutes in the same manner as described above, after the vibration motor 309 is temporarily separated, the rotary clamp 200 for fixing the closed transformer 100 is rotated up and down 110 ° While the cleaning liquid is strongly sprayed and cleaned in a random manner (not in a predetermined direction) at a time by the nozzle apparatus 303 provided in various directions, the cleaning operation is completed by repeating these operations several times.

 Here, as described above, the nozzle device 303 for cleaning is sprayed at high speed sequentially at different angles, and automatically rotates to clean up to the inside of the closed transformer 100 by using the rotary clamp 200.

In addition, the object of the cleaning operation includes not only the waste transformer 100 but also all materials inside the washing machine 300.

On the other hand, when the cleaning liquid used in the washing machine 300 is inspected by the content sensor and the cleaning operation is sensed through the sensor, the drying process continues to operate the button to proceed to the drying process.

At this time, the method of determining the completion of the cleaning operation is installed in the pipeline discharged from the washing machine 300, a system capable of automatically determining the completion of the cleaning by the conductivity meter, the electrical conductivity is preset range When it arrives, it employs a method of transmitting a signal to the operator in a transmission method by two or more processes.

That is, when a signal is transmitted to the worker for completing the cleaning operation, the worker takes a sample of the cleaning liquid discharged from the drier 300 using a microscope, visually inspects three times at a magnification of 1,000 times, and takes a photograph (digital). After that, the washing operation is finished.

When the cleaning process is completed, the drying process is performed after maintaining the inside of the washing machine 300 in a vacuum state.

The drying process is heated to a maximum of 60 ° C through the heater 302 in a vacuum (maximum 40mmHg state).

When the cleaning and drying process (S2) through the washing machine 300 is completed in this way, the centrifugation process (S3) by the centrifuge (500) and the chemical treatment process (S4) by the chemical treatment facility are performed.

First, as shown in Figures 2 and 7, the centrifugal separation step (S3) is separated through a well-known centrifuge (500), the insulating oil and the cleaning liquid washed through the washing machine 300, but not less than 2ppm Insulating oil is sent to the storage tank 400, and the cleaning liquid is sent to the cleaning liquid tank 502 to be recycled.

 That is, since the bottom of the dryer 300 is designed so that the insulating oil can be collected at a point inside the grating facility and the rail at the time of construction, the insulating oil cleaned by the cleaning process and the cleaning liquid used in the cleaning process are mixed. After being gathered in one place, the mixture is transferred to the receiver tank 501 and then centrifuged through the centrifuge 500.

When the cleaning liquid and the insulating oil (solid phase; 2 ppm or more) are separated by the centrifuge 500 as described above, the separated cleaning liquid is sent to the cleaning liquid tank 502 for recycling in the washing process, and the separated insulating oil (solid phase; 2 ppm or more). Will be sent to the storage tank 400 or more 2ppm.

At this time, the sludge generated in the centrifugal separation process through the centrifugal separator 500 is condensed after being collected in the turbidity treatment tank 504.

When 2ppm or more of insulating oil separated through the centrifugal separation process (S3) by the centrifuge 500 and 2ppm or more of insulating oil sent from the inside of the washing machine 300 are stored in the storage tank 400, the storage tank ( The insulating oil stored in 400 is sent to the chemical treatment facility and neutralized through the chemical treatment process (S4).

That is, as shown in Figures 2 and 8, the chemical treatment process (S4) according to the present invention reduced the concentration of 2ppm or more liquid PCB (PCBs) to a concentration of 2ppm or less through the K ⁺ catalytic reaction using a solid catalyst It is a neutralization process.

Here, as a facility for the chemical treatment process (S4) according to the present invention, the automatic control panel 600 for controlling each device of the facility and displaying the operating state, and initially heating the insulation oil of PCB (PCBs) 2ppm or more Insulating oil heater (601), which is a device for the mixing, and reactor tank (602, REACTOR TANK), which is a device for reacting by mixing and mixing a mixture of insulating oil and catalyst and a solid sample and a liquid sample of 2 ppm or more, and the insulating oil processed by reacting in a reactor A pair of decanters (603, DECANTER) which is a device for separating the sludge and insulating oil.

The chemical treatment process (S4) according to the present invention is performed using the chemical treatment facility as described above. The chemical treatment process (S4) applied to the present invention includes PCBs in insulating oil injected into the waste transformer 100. ) Is a neutralization process that dehalogenates (dechlorinates) and detoxifies to a prescribed concentration using a solid catalyst and a liquid solvent.

Here, as the catalyst and the solvent, the product name, S / CDP R1 RED (hereinafter referred to as "solid sample") produced and sold by SEA MARCONI TECHNOLOGIES of Italy, and L / CDP R1 RED Solvent (hereinafter referred to as "liquid sample") is used.

That is, the general information of the solid sample and the liquid sample is shown in Table 2 below.

The solid sample, which is the catalyst, mainly contains alkali hydroxide and polyether (polymer) as the main active mixture, and the porosity of Inorganic Oxides (SiO2, Al2O3, Fl2O3-a compound such as diatomaceous earth) By precisely inserting the K ⁺ element into the catalyst to prepare a catalyst so that it remains only harmless to the sludge produced after the chemical reaction.

These catalysts and the insulating oil is to dechlorinate the insulating oil through a chemical reaction such as the following chemical equation.

(Chemical reaction)

In this case, M = K ⁺ , n and m are chlorine numbers in the range of 0 to 5, R is a hydrogen atom or a hydrocarbon.

And n on the polymer is the monomer number and can range from 2 to 200.

That is, the reaction between the polymer and the salt of the catalyst, which is a solid sample, results in contact with the PCB to remove chlorine, and eventually the chlorine reacts with the alkali on the PCB to become chlorinated.

The chloride is left in the catalyst or insulating oil as a solid sample, and is then discharged to the sludge by the decanter 603 of the chemical treatment facility.

Hereinafter, a process of neutralizing the insulating oil and discharging the sludge in the chemical treatment facility performing the chemical treatment process S4 will be described.

First, at least 2 ppm of PCBs in the storage tank 400 having at least 2 ppm of insulating oil stored therein is transferred to the insulating oil heater 601 of a chemical treatment facility, and then controlled by a heating controller. Heat to 60-80 ° C.

Then, the heated insulating oil is moved to the reactor tank 602.

In the reactor tank 602, the solid sample and the liquid sample are automatically added, mixed with insulating oil of PCB or more than 2 ppm, and reacted with a reactor stirrer (REACTOR STIRRER) inside the reactor tank 602 (not shown) for 5 hours. Mixer

At this time, when the pollutant concentration of PCBs in the automatic control panel 600 (ELECTRIC BOARD) is less than 2ppm, it is checked whether the operation ends by a beep notification.

Of course, it is desirable that the work manager check and record the ppm concentration of the insulating oil neutralized every hour.

The processed insulating oil in the reactor tank 602 is transferred to the decanter 603 to separate the insulating oil of less than 2 ppm and sludge in a solid state.

At this time, the insulating oil is processed and separated to less than 2ppm is transferred to PCBs (PCBs) less than 2ppm storage tank 604, the sludge is moved to a separate storage location to be embedded or incinerated and then consigned.

On the other hand, the waste power equipment recycling treatment system according to the present invention includes an oil vapor treatment step (S5) in addition to the chemical treatment step (S4).

That is, as shown in FIG. 2 and FIG. 9, the oil vapor treatment process S5 includes a gas generated in the cleaning and drying process S2, the chemical treatment process S4, and the storage tank 400 stored and stored at least 2 ppm. It is a process of collecting oil vapor (waste insulation oil containing PCBs) that is generated from.

The oil vapor treatment step (S5) is made through the condensation unit 700 and the adsorption unit (701).

The oil vapor treatment step (S5) using the condensation unit 700 and the adsorption unit 701 as described above, first, the oil vapor generated in the dryer 300 during the cleaning and drying step (S2), and chemical treatment The oil vapor generated in the reactor tank 602 and the oil vapor generated in the storage tank 400, which is stored and stored at least 2 ppm, are transferred to the condenser of the condensation facility 700 by using the vacuum pump 703 during the process S4. To condense.

Then, the liquid insulating oil condensed through the condenser of the condensation unit 700 is transferred to the storage tank 400 which stores and stores the insulating oil of 2 ppm or more again, and the uncondensed residual gas is absorbed by the adsorption tower of the adsorption unit 701. Transported to the (air discharge facility).

At this time, the contaminated adsorbent after filtration by the adsorption tower is washed and dried in the dryer 300 and reused in the adsorption tower.

On the other hand, as shown in Figures 2 and 10, the solid material of less than 2ppm contained in the waste transformer 100 and the cleaning process is completed in the cleaning and processing process (S2) is dismantled by type to separate the sorting container 800 And then recycled or consigned.
