Description

Method for manufacturing solid fuels using by-products of vehicles {Methods for manufacturing of solid fuels using waste material of cars}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for recycling by-products of a vehicle, and more particularly, to a method for manufacturing a solidified fuel using by-products of a vehicle for high value-adding of waste resources by recycling the by-products of a vehicle that has been disposed of in a total amount and incinerated as fuel. .

Recently, due to the development of the industrial society and the improvement of living standards, automobiles are increasing in a huge amount, and in proportion, the amount of waste from the discarded cars is also generated.

Therefore, in the related art, as a method for treating the waste by-products as described above, a waste cell interior of a vehicle, such as Korean Patent Application No. 1991-0013411, "Method for regenerating FVC and urethane foam from the waste interior of automobile," Classifying the plastic foam having a lower density than the plastic cell, and pulverizing the plastic article to form a mixture of the plastic cell particles and the plastic foam particles, and the plastic foam particles of the plastic cell particles to prevent electrostatic forces from each other. Electrostatically removing the mixture, forming a plastic cell through the air stream to form two density portions of high density particles separated and sinking in the first direction and low density particles separated and rising in the opposite direction of the first direction. By separating the mixture of plastic foam particles However, the above-mentioned method is merely a method of separating only F-C and urethane foams, and thus the types of by-products of the recent years of waste cars are foam sponges, seat cushions, interior buffers and vinyl seat covers, Given that various different materials such as ABS bumper and instrument panel are mixed, this is not a desirable treatment method.

In other words, the sorting of waste by-products by using the inaccurate density difference is difficult to achieve accuracy, which is not efficient in consideration of the characteristics of the plastic product that can only be degraded by the inclusion of some impurities. In addition, the method as described above is difficult to collectively process all of the by-products of the waste car, and the work is very cumbersome, such as to separate the fib C and urethane foam of the waste car by-products have a rather uneconomic waste.

Therefore, until now, almost all waste by-products have to be incinerated or landfilled. Thus, in the case of incineration, fuel waste, odors and dioxins, etc. Of course, it is very unfortunate to simply burn off the combustible materials with huge calories while importing fuel like Korea.

Therefore, the inventors of the present invention are more urgent than ever because of the finite nature of fuel resources, and thus, while studying the utilization of automobile by-products currently being disposed of by incineration and landfill, almost all automobile by-products are flammable. In particular, it is possible to significantly reduce the waste of resources and to prevent environmental pollution by fueling these materials with the fact that they can generate high calories.

To this end, the present invention is a step of crushing the discarded car, the step of screening only by-products except for metals (including metals, non-ferrous metals) from the crushed car by-products, and by-products excluding the selected metals (hereinafter referred to as non-metal by-products) ) Into the crusher together with the waste plastic to crush again and uniformly mixed with each other, and to pass the mixed crushed material into the cylindrical body equipped with a hot air blower to control the moisture content by the hot vortex air and Storing the crushed mixed crushed material in a hopper, placing a predetermined amount of crushed mixed crushed material from the hopper into a friction type melt mixer, pulverizing and mixing the crushed product more uniformly; When plastic components are melted by frictional heat in the friction type melt mixer Causing the waste plastic by-products to entangle with each other, and when the molten plastic component is combined with the waste vehicle by-products to form agglomerates, by spraying water to cool to form small granular pellets. To provide a method for producing a solidified fuel using the by-product of.

When manufacturing the solidified fuel using the by-product of the present invention for achieving the above object by each process is as follows.

First, putting the discarded car into the crusher, and crushing, and sorting only by-products except metals from the crushed car by-products, and put the non-metal by-products except the selected metals into the crusher together with the waste plastic and crushed again. At the same time, the step of uniformly mixing with each other, passing the mixed crushed material into a cylindrical body equipped with a hot air blower to control the moisture content by the hot vortex air, and to store the mixed crushed material controlled in the hopper And putting a predetermined amount of the mixed crushed material measured from the hopper into the friction type melt mixer and pulverizing the mixture more uniformly. The mixed crushed material is subjected to frictional heat in the friction type melt mixer. Melting and tangling with the waste car by-product pieces And, when the molten plastic component is combined with the waste car by-products to form agglomerates, it is made of a step of forming a small granular pellet by spraying water to cool, thereby producing a vehicle by-product as a solid fuel It can be.

This will be described in detail for each step for the preferred embodiment.

Example

The waste cars required for the present invention (hereinafter referred to as junk cars) are collected from each junkyard, and most of the junk cars are supplied in a flat crimped state by a press to reduce the volume. It does not matter in the present invention.

The collected waste cars 100 are put into the shredder 110 by a crane or other equipment to be shredded, the shredder is a longitudinal hammer type is mainly used.

In addition, the car fragments crushed by the shredder 110, that is, the waste car by-products 111 are subjected to the sorting device 120 using the wind or magnetic force, the sorting device is non-flammable and easily crushed, such as metal and non-ferrous metal components. It is to filter out substances that are not.

Therefore, only the non-metal by-products 121 are sorted by the sorting device, and the selected non-metal by-products 121 are put together in the shredder 130 together with the waste plastics 122 to be crushed once again and mixed uniformly with the waste plastics at the same time. It is done.

At this time, the waste plastic 122 is added for the binder (binder) function of the non-metal by-products 121, which are poor in meltability and not easily fused with each other, such as foamed urethane, vinyl, ABS, etc. The amount of the 122 may vary slightly depending on the content of the plastic contained in the non-metal by-product 121, but the total amount of plastic to be added for the desired binder function is the content of the plastic contained in the non-metal by-product 121. It should maintain at least 20% in weight ratio including

Plastic in the present invention means a thermoplastic resin having adhesion, in particular polyethylene, polypropylene, polystyrene, polyvinyl and the like are mainly used, of which polyethylene was the most preferable result was obtained.

The crusher 130 preferably uses an electric single rotor type, because it can increase the efficiency of the work.

In this case, the mixed crushed objects 131 crushed to within 5 cm by the crusher 130 are transferred by the conveyor belt 140 to pass through the cylindrical body 150 provided with the hot air blower 151. As the mixed crushed particles 131 pass through the inside of the cylindrical body, moisture is evaporated by the hot vortex air from the hot air blower, thereby controlling the moisture content.

At this time, the moisture content control of the mixed crushed material 131 is a very important factor in the present invention, because the formation time of the pellet is significantly changed depending on the moisture content of the mixed crushed material 131.

That is, when the formation of the pellets 170 is delayed, the energy consumption due to the operation of the device is inevitably increased, thereby lowering the productivity and increasing the manufacturing price.

The difference in pellet formation time according to the moisture content is shown in Table 1.

Water content Pellet Forming Time 7% 14 minutes 17% 19 minutes 27% 24 minutes

In other words, for every 10% of moisture content, pelleting time was additionally 5 minutes.

Next, the mixed crushed matters 131 of which the moisture content is adjusted are stored in the hopper 160 because the friction type melt mixer 170 can digest only a predetermined amount of the mixed crushed matter 131.

Therefore, a predetermined amount of the mixed crushed matter 131 is measured from the hopper and introduced into a known friction melt mixer 170. The mixed crushed matter 131 is crushed and uniformly again by the friction melted mixer 170. It is mixed.

In addition, the mixed crushed matter 131 injected into the friction melter 170 is contained in the mixed crushed matter 131 by frictional heat generated while rotating by the rotary blade 172 formed on the bottom of the frictional melted mixer 170. As the plastic component is melted first, it is also entangled with the pieces of non-metal by-products 121 contained in the mixed crushed product 131.

At this time, when the temperature of the mixed crushed object 131 reaches about 160 ° C., the molten plastic component is combined with the non-metal by-products 121 to form a lump. In this case, water is injected into the injector 171 to cool the diameter. Small granular pellets 180 within this 1 cm are formed.

As described above, the present invention has a very small granular shape, and the waste car by-products having a high calorie content are uniformly mixed and fused by flammable plastics having a low ignition temperature, so that the ignition is facilitated, the combustion power is improved, and the fire power is uniform. As a result, there is no shortage of replacing solid fuel.

According to the present invention, waste plastics are mixed with waste by-products made of various components to produce small pellets of granules, so that the ignition is easy, the combustion power is good, and the thermal power is uniform, so that the plastic house, power plant, and various other solid fuels can be used. By providing free or low cost to the place of use, it is possible to improve the economic utility value rather than disposing through conventional landfill or simple incineration, thereby greatly contributing to the high added value of the waste resources and environmental protection.
