Description

Recarburizer using wasted tire

The present invention relates to a coal ash using waste tires.

Waste tires are recycled in various forms because they are undesirably discharged due to the large amount of environmental pollutants. However, due to the narrowness of the recycling, it is not fully recycled, and thus, it is difficult to deal with environmental pollutants. It is possible to make recycled tires with waste tires, but there are limitations because they are legally restricted, and there are also difficulties in going through many manufacturing processes to recycle waste tires into new tires.

The present invention invented a coal material using waste tires by thermally decomposing waste tires, extracting oil, and confirming that carbon produced as a result can be utilized as a coal ash.

[Patent 1] Korean Laid-Open Patent Publication No. 10-2001-0018676, titled "Electric furnace charcoal composition using waste generated in steelworks"

Gypsum ash is a carbon material used to replenish carbon components in steel or to control carbon content in steel production. It is used to increase purity and remove strength of steel, and coke is generally added. Injecting charcoal into the molten metal also reduces the cost of electricity as a heat source, maintains carbon targets, prevents peroxide oxidation, facilitates the formation of molten slag, and denitrification effects. Briquettes are added in an amount of about 1-4%, depending on the application, to control the carbon content in the steel components.

Kinds of coal ash include, for example, coal, oil, and graphite.

Natural graphite petroleum is a raw material is expensive, but the carbon content is constant, waste electrode rod petroleum has a high purity, but the supply is not constant, expensive and dust has a lot of disadvantages. Other charcoal materials include anthracite and pitch. As the particles of the component used as the pellets, particles having a thickness of about 0.3-5 mm are used. In general, the carbon component contains 0.03-0.5% sulfur component and ash content of 0.5-0.8% to 0.5-16% ash, other moisture, volatile components and the like. Sulfur content adversely affects the iron structure and should be less than about 0.5%

At least, the carbonaceous material requires a purity of 80% or more of carbon, and the higher the purity is, the higher the purity, the higher the price is exponentially expensive. Therefore, at present, about 75% purity is used.

The present invention has an object of the present invention to provide a waste tire as a charcoal.

In addition, the charcoal material here can be used as activated carbon by reprocessing by mixing other materials with it. For example, a mixture of innisian coal and softwood sawdust can be used as activated carbon.

The main configuration of the present invention is a peat containing 82.69-86.90 parts by weight of carbon and 0.1-0.5 parts by weight of sulfur, based on 100 parts by weight of the entire carbonaceous component produced by pyrolysing waste tires in a pyrolysis carbonization machine. Characterized in that the ash, the particle size of the coal ash is characterized in that the size of 1-3mm, the coal ash, the step of crushing the waste tires into the granulator 204; Passing a magnetic separator 206 to remove metal components contained in the crushed waste tire chip; Charging a waste tire chip through a magnetic separator into a carbonizer (80); Carbide discharged after carbonization in the carbonizer 80 is passed through the magnetic separator 220, characterized in that for using the carbide produced by the step of removing the metal component, the carbonization treatment in the carbonizer 80 After the step of removing the metal components by passing the carbide discharged through the magnetic separator 220, characterized in that using the desulfurized charcoal material by passing through an extruder having a temperature of 150 to 300 degrees Celsius.

According to the present invention, the waste tire can be utilized as a charcoal material to further extend the recycling range of the waste tire, and the oil which is additionally produced during the carbonization of the waste tire can be used as another heat source.

EMBODIMENT OF THE INVENTION Hereinafter, it demonstrates based on an accompanying drawing in order to demonstrate the coal ash which concerns on this invention.

1, the treatment of the waste tire 200 is supplied to the hopper 201 and conveyed by the conveying conveyor 202. After the metal material is selected by the magnetic separator 203, 204) and pulverized to a predetermined size of about 20 mm.

Since the granulator 204 is difficult to crush small at a time, the granulator 204 is provided with up to two nails and is crushed gradually. Preferably, 2-3 pieces of the granular elements 204 are connected and broken in succession 2-3 times in succession

Then, it is conveyed by the vertical conveyor 205, the metal material is removed again by the magnetic separator 206, and the separating work is performed by the wind separator 207 according to the weight. Then, if necessary, it is dried through a hot air dryer 209.

The reason for performing the drying operation is to sufficiently dry the carbonized object to prevent fusion of the carbonized object and to vaporize volatile components in the carbonized object to prevent fire and explosion

The hot air supplied to the hot air dryer 209 is supplied to the hot air dryer supply fan 210, and hot air is supplied by heating by the hot air dryer heat exchanger 208. This hot air dryer uses steam as a heat source to facilitate temperature control and reduce energy consumption. The supplied hot air is directly contacted in the dryer and hot air is dried by convection. According to the hot air dryer (209), the drying speed is fast and the low temperature drying can prevent fire and explosion

The dust or the like generated in the hot air dryer 209 is collected by the dust collector 212 and exhausted by the exhaust fan 211. The waste tire chip that has passed through the hot air dryer 209 is stored in the storage tank 213, ) To the carbonizer (80) via the feed hopper (226) and the feed hopper (225) to carbonize the waste tire waste piece

The carbonizer (80) is a device for vaporizing volatile components contained in a raw material by an indirect heating method in a closed-type low-oxygen atmosphere, and the heat source is hot air and is treated by pyrolysis gasification treatment. It is a reduction method that does not generate contaminants due to oxidation, it generates almost no waste, it is possible to produce carbide as a resource, it is possible to recover energy by oil and dry gas, And dioxin-free, non-polluting resources

On the other hand, the general incineration facility is an oxidation treatment method by combustion, and it is an exothermic reaction. It is burned by oxygen supply and is an open type and steam production method by recovering waste heat. These incineration facilities are due to the oxidation method, and as industrial wastes, air pollutants such as dioxins are generated, resulting in low resource conversion rate, additional waste disposal costs, incineration ashes of more than 10%, complex control and high maintenance cost

As shown in FIG. 2, the carbonized furnace structure of the carbonizer 80 is composed of a screw shaft 171 formed in a vertically layered structure and a multi-stage screw conveying structure in which a screw integrally formed therewith is formed. It is possible to prevent clogging troubles and to achieve complete sealing by horizontally feeding sludge by the screw and smooth lower conveyance and to shorten the carbonization time by controlling the screw shaft 171 and the number of revolutions of the screw. The internal temperature of the carbonizer 80 at the carbonization treatment of the waste tire chip is about 510 to 690 degrees centigrade. The configuration of the carbonizer (80) can maximize the heat exchange, shorten the time required for carbonization, reduce the generation of waste, and simplify the equipment maintenance.

In addition, since the carbide produced by the carbonization treatment is porous, it has characteristics similar to those of activated carbon having a comparative surface area of 1/10 of that of activated carbon, and has a calorific value of 10,000 to 15,000 KJ / kg, . Therefore, it can be used as fuel because it is made of solid tube or solid fuel.

It can be used as soil improvement agent, deodorant, adsorbent, humidity control, red tide removing agent, snow melting agent, asphalt aggregate, etc. since it is lightweight, odorless and sterile, granular, air permeable, permeable, water retaining, medium to weak alkaline, It can be used for various purposes. In particular, the present invention utilizes this as a charcoal ash.

The fuel supply for the carbonization treatment is supplied by the oil supply pump 100

At the time of combustion in the carbonizer (80), the odor air of the building is also sent to the combustion air supply fan (215) and burned through the ignition furnace (216) to be removed. The waste after the carbonization treatment in the carbonizer 80 removes the metal material through the magnetic separator 220 and is stored in the carbonizer storage tank 222 via the vertical conveyor 221 and recycles the carbonized material to the carbonaceous material

3 and 4 show the results of analyzing the carbide briquettes of the waste tires.

3 and 4 is a test analysis of the carbide produced in accordance with the present invention, the carbon component is 82.69-86.90% by weight, the sulfur component was detected about 3.52-3.63% by weight.

Currently, the carbonaceous material has a carbon content of 75% by weight, so that only about 80% of the carbon content can be sufficiently utilized as a carbonaceous material. Therefore, there is no problem with oxygen, but the problem is sulfur.

In order to use as a briquette material, sulfur of about 0.1-0.5 parts by weight or less is preferably included. Therefore, in the present invention, a lot of sulfur components are subjected to desulfurization treatment as necessary. In the desulfurization method, a sulfur component is removed by burning at a temperature of 150 to 300 degrees Celsius. As an example of the desulfurization treatment method, the method of Patent Application No. 2007-119424 can be used

The above method relates to a desulfurization treatment method of waste rubber by a continuous extrusion method, in the desulfurization treatment method of waste rubber, the first step of pulverizing waste rubber to produce fine powdered waste rubber, and by a twin screw extruder The present invention relates to a desulfurization treatment method for waste rubber, comprising only two steps of desulfurization of the waste rubber that has undergone the first step process at a temperature of 150 to 300 degrees Celsius using only heat and transfer force. The desulfurization treatment method of the waste rubber uses a continuous extrusion method, consumes a short reaction time in a twin-screw extruder, and does not use an expensive desulfurizing agent at all, and thus has an excellent cost saving effect. For example, in the same manner as above, the desulfurized charcoal contains at least 0.1-0.5 parts by weight of sulfur components.

The coal ash produced in accordance with the present invention was free of minerals. However, the conventional anthracite-based briquettes contain minerals, which adversely affect steelmaking. Therefore, the mass produced by the present invention can be said to be advantageous than the conventional anthracite-based peat material.

The invention may also further undergo a granulation step before or after the desulfurization treatment described above. Carbide discharged from the carbonizer 80 has a disadvantage that the granular material is blown too hard and the specific gravity is low, when the strong injection of the coal ash from the lower or upper portion of the molten steel during steelmaking. Therefore, it is preferable that at least about 1 to 3 mm particle size comes out. Pressure molding method can be made by a variety of methods, such as using an extrusion molding machine that is cut when the exiting the hole of 1-3mm by inserting the burnt material from the existing extruder. Since such granulation apparatuses already exist in various forms, detailed description thereof will be omitted.
