Description

Waste gasification device {APPARATUS FOR GASFICATION WASTE}

The present invention relates to a waste gasification device, and more particularly, since waste can be gasified while being continuously transported, and there are many heat exchange sections where H2O can be steamed at a high temperature, a large amount of steam is injected to produce high-quality synthesis. It relates to a waste gasification device capable of producing a large amount of gas, secondly, being able to miniaturize the product due to continuity (high throughput, speed), and being able to treat the waste regardless of the type and characteristics of the inputted waste.

In general, plastics are variously used as essential materials in many other fields including electricity and electronics in modern times due to processability, light weight, toughness, corrosion resistance, easy generation and mass productivity. Plastics are widely used due to these excellences, but as the industry develops, the production capacity also increases exponentially, and the amount of waste also increases exponentially in proportion to it. Accordingly, a large amount of plastic waste is generated, and the problem of disposal of waste plastic has become a social issue.

Existing waste plastic treatment methods have mostly relied on incineration, landfill, and recycling. Although incineration is generally the easiest method to achieve the dual effects of reducing waste and recovering waste heat, problems arise due to pollutants generated when polymer waste such as waste rubber or waste synthetic resin is directly incinerated. In particular, the problem of exposure to carbon monoxide, hydrogen chloride, dioxins and heavy metals, which are secondary pollutants generated during the incineration of waste plastics, must be solved.

In addition, in the case of landfill, it is difficult to decompose, which hinders soil contamination and stabilization of the landfill.

In order to solve the above problems, a plan to use waste as an energy source has emerged, and research on this has been actively conducted.

Methods of obtaining energy sources by treating wastes can be largely classified into pyrolysis and gasification.

In the case of the gasification reaction, the gasification reaction using coal as a raw material is the most actively researched, and in foreign countries, it has already reached the commercialization stage.

However, in the case of such coal, since its reserves are limited, it is emerging as an alternative to petroleum for a while, but it cannot be completely replaced. For this reason, research is being actively conducted to use waste generated in the production process as a raw material for gasification. Types of waste include various types of biomass such as grape skins and sawdust and waste plastics, among which research on gasification using waste plastics as raw materials is being actively conducted.

In the gasification reaction, a lot of research is being conducted on the development of a process for suppressing secondary pollutants using a high-temperature generating device such as plasma.

In the process of pyrolysis of general waste using ultra-high temperature plasma, the plasma used as a heat source is a state in which electrons are excited by specific energy in addition to gases, liquids, and solids and exist in a state separated from atoms, which is called a fourth material. . When this plasma state is reached, it retains very high energy as latent heat, but is placed in an unstable state.

However, if the system that maintains the unstable state is removed or out of this system, it is ionized locally and has an electric charge, but it is electrically neutral overall. The temperature of the plasma varies greatly inside and outside the flame, but the temperature at the center is estimated to be between 10,000 and 20,000 °C, and the outside temperature is estimated to be between 3000 °C and 4000 °C.

By maintaining the reaction furnace at a high temperature of 1200 °C or higher using the characteristics of the plasma, thermal decomposition is caused, and synthesis gas composed of carbon monoxide and hydrogen can be formed in the ion degree range.

In addition, it is possible to eliminate secondary environmental pollutants by minimizing the emission of secondary pollutants such as dioxins and furans, which are suppressed or decomposed at high temperatures.

Therefore, the plasma process has the advantage of obtaining a fast thermal decomposition rate and efficiency. In addition, the residue after incineration can be stably treated by vitrification, and ash is not generated, and a small-scale incineration facility can be operated, which is advantageous for waste treatment and securing a fuel source.

Publication No. 10-2008-0045574 relates to a process and apparatus for purifying syngas from waste using plasma pyrolysis process technology. Recycled and pyrolyzed gas produces refined syngas through developed/applied refining facilities, and refined syngas is applied to the developed recycling facility to produce high-purity hydrogen, carbon monoxide, fuel gas such as methanol, and gas turbine power generation and a process and apparatus for purifying syngas from waste that can expand application fields to electricity production through gas engine power generation, recovery of valuable metals, gasification of coal, and securing of carbon credits.

This is a comparison table showing the difference between the method of gasification by high-temperature pyrolysis of waste and the general low-temperature pyrolysis method.

The waste gasification device 1 according to an embodiment of the present invention includes a transfer guide 10, a transfer unit 20, a housing 30, a screw unit 40, and a spark plug 80 and a storage unit 70 It may include at least any one or more of them.

The transfer guide 10 may be formed in a tubular shape having a substantially circular cross-section or polygonal cross-section.

The drawing shows an example in which the transfer guide 10 is formed in a cylindrical shape.

The transfer guide 10 has an inlet 10a into which waste is input is formed on an upper surface of one side.

At this time, the waste may be plastic, but it is revealed that the type of waste to be gasified in the present invention is not limited to plastic.

A transfer passage 10c for transferring waste is formed inside the transfer guide 10 .

A hopper H is disposed above the inlet 10a. That is, the waste put into the hopper H is supplied to the transfer passage 10c through the inlet 10a.

At this time, the objects injected into the hopper H are not limited to waste, and solid, liquid, and gaseous fuels (Waste, Biomass, Coal (Char), and Residual Oil) may also be introduced.

In addition, a blocking device may be provided in the hopper H to prevent external air from entering the transfer passage 10c when waste is introduced.

At this time, since the blocking device is a technology commercialized in waste gasification equipment, a detailed description thereof will be omitted.

At the end of the transfer guide 10, an outlet 10b protrudes outward through the housing 30 is formed.

The outlet 10b is formed to be bent downward.

The gas-generated waste is discharged through the outlet 10b and collected in the collection container 90.

On the upper surface of the transfer guide, a discharge pipe for discharging gas generated when the waste in the transfer passage 10c is heated by the gas supply unit 60 and the oxygen supply unit 100 to be described later to the additional transfer passage 30c of the housing 30. (11) is installed through.

A plurality of discharge pipes 11 may be installed to be spaced apart from each other on the upper surface of the transfer guide 10 so as to increase the discharge efficiency of the gas generated by the waste.

The conveying unit 20 is configured to convey the waste put into the conveying passage 10c of the conveying guide 10 in the direction of the discharge port 10b.

That is, the waste gas generated by the transfer unit 20 is discharged through the outlet 10b.

The transfer unit 20 may be formed in the shape of a circular shaft having a predetermined length and diameter.

The transfer unit 20 is rotated in place by the power of the motor M.

The motor (M) may be fixed to the upper surface of the table (T) for installing the waste gasification device 1 according to an embodiment of the present invention.

The motor (M) is located outside the conveying part 20 and only the axis of the motor (M) is coupled to one end of the conveying part 20 in the conveying passage 10c of the conveying guide 10.

Accordingly, the transfer unit 20 may be rotated in place in the same direction as the shaft of the motor M.

The transfer unit 20 further includes an additional screw unit 50 to continuously transfer the waste.

The additional screw portion 50 is formed along the outer periphery of the conveying portion 20 .

Therefore, when the motor (M) is operated to rotate the conveying part 20 and the additional screw part 50, and then the waste is put into the hopper (H), the additional screw part 50 moves the waste toward the discharge port (10b). will be transported

At this time, the waste is introduced after heating the additional transfer passage 30a with oxygen and gas to a certain temperature or higher. This will be explained in detail below.

The additional screw unit 50 continuously transports the waste, so that the waste does not become stagnant in the inlet 10a.

The housing 30 may be formed in a tubular shape having a substantially circular cross-sectional shape.

The housing 30 may be fixed to the upper surface of the table (T).

An additional transfer passage 30a is formed inside the housing 30 .

Gas and oxygen for pyrolyzing waste are supplied to the additional transfer passage 30a of the housing 30.

Gas is supplied by the gas supply unit 60 .

And, oxygen is supplied by the oxygen supply unit 100.

The gas supply unit 60 is connected to the housing 30 through a connection hose 61 and a connection pipe 62 to supply gas to the additional transfer passage 30a.

The oxygen supply unit 100 is connected to the housing 30 through the connection hose 101 and the connection pipe 62 to supply oxygen to the additional transfer passage 30a.

The connection hose 61 is connected to the gas supply unit 60 and the connection pipe 62, and the connection pipe 62 is installed through the housing 30.

The connection hose 101 is connected to the oxygen supply unit 100 and the connection pipe 62, and the connection pipe 62 is installed through the housing 30.

The gas supply unit 60 is a known product capable of discharging and supplying gas through a certain pressure.

The oxygen supplier 100 is also a known product capable of discharging and supplying oxygen through a certain pressure.

The gas discharged from the gas supply unit 60 sequentially passes through the connection hose 61 and the connection pipe 62 and is supplied to the additional transfer passage 30a of the housing 30.

Oxygen discharged from the oxygen supply unit 100 sequentially passes through the connection hose 101 and the connection pipe 62 and is supplied to the additional transfer passage 30a of the housing 30.

Then, gas and oxygen are moved along the screw part 40 in a stationary state in the additional transfer passage 30a.

The transfer guide 10 is accommodated in the additional transfer passage 30a of the housing 30 in a horizontal form.

The screw portion 40 is formed along the outer periphery of the transfer guide 10 .

Since the screw part 40 is formed in a screw shape, the additional transfer passage 30a is formed in a screw shape.

Therefore, the gas and oxygen injected into the additional transfer passage 30a are transferred while swirling, and during the transfer process, the gas is burned and ignited by the operation of the spark plug 80.

If the screw part 40 does not exist, the space of the additional conveying passage 30a is secured, but the space of the additional conveying passage 30a is narrowed by the size of the screw part 40.

That is, in order to completely burn the gas, a sufficient amount of oxygen and space must be secured, but since the screw part 40 divides the space of the additional conveying passage 30a into several sections and narrows it, the gas passes through the additional conveying passage 30a. will result in incomplete combustion. Higher temperatures are generated when incomplete combustion occurs than when complete combustion occurs. Therefore, the temperature of the housing 30 and the additional conveying passage 30a can be made high through the screw part 40, so that the waste put into the conveying passage 10c can be quickly and efficiently heated and gasified.

Additionally, the additional transfer passage 30a may be filled with catalyst.

The catalyst may be filled in the additional transfer passage 30a when manufacturing the waste gasification device according to an embodiment of the present invention.

The catalyst is solid and may be formed in a bead shape, but the type of catalyst in the waste gasification device according to an embodiment of the present invention is not limited, and any one of various catalysts used in the gasification device may be selected and applied.

The catalyst further reduces the space of the additional transfer passage 30a.

The catalyst minimizes the space to prevent rapid combustion.

Specifically, due to the specific gravity of the catalyst, the space of the additional transfer passage 30a is narrowed even though gas and oxygen exist in the additional transfer passage 30a, so that a more perfect incomplete combustion section can be formed.

By forming a high-temperature catalyst section in the additional transfer passage (30a), the gas generated from the waste when passing through the catalyst layer is first reformed.

That is, the catalyst, which has been heated together due to incomplete combustion, reforms the gas generated from the waste.

In addition, the catalyst also serves as a filter for filtering fine dust of waste flowing back through the inlet 10a.

The condition of a material capable of functioning as a catalyst must be able to withstand high temperatures of about 600 ° C to 1,500 ° C without change in shape or character.

In addition, the catalyst is preferably made of porous material, and the size or shape is irrelevant, but it is preferable to be constant.

Additionally, the waste gasification device according to an embodiment of the present invention may include an oxide supplier (not shown).

The oxide supply unit includes a connection pipe (not shown) installed through the housing 30 to supply oxide to the additional transfer passage 30c.

At this time, the oxide may be at least one or more of air, oxygen, and steam.

The spark plug 80 is installed through the upper surface of the housing 30 .

The gas in the additional transfer passage 30a is incompletely combusted by oxygen and sparks generated from the spark plug 80.

The storage unit 70 is configured to store waste gas discharged through the discharge pipe 11 to the additional transfer passage 30a.

To this end, the storage unit 70 may include an intake fan 71 , a cooling fan 73 , and a storage unit 74 .

The intake fan 71 includes an intake pipe 72 installed through the housing 30 .

When the intake fan 71 operates, the gas in the additional transfer passage 30a is taken in through the intake pipe 72.

For example, a certain area of the intake pipe 72 may come into contact with the cooling fan 73 .

Accordingly, the gas is cooled to a certain temperature by the cooling fan 73 while being sucked into the intake fan 71 through the intake pipe 72 .

As another example, a certain area of the intake pipe 72 may cross the front of the cooling fan 73 .

Accordingly, the gas is cooled to a certain temperature when passing through the region of the intake pipe 72 crossing the cooling fan 73 .

The storage unit 74 has a tank structure in which the inside is sealed.

The storage unit 74 is connected to the intake fan 71 through a connection line 741.

Accordingly, the gas taken in by the intake fan 71 is stored in the storage unit 74 .

Next, an example of gasifying waste through the waste gasification device 1 according to an embodiment of the present invention will be described.

First, the gas supply unit 60, the oxygen supply unit 100, and the oxide supply unit are operated to inject gas, oxygen, and oxide into the additional transfer passage 30c.

In addition, the ignition plug 80 is operated to make the additional transfer passage 30c high.

At this time, the additional conveying passage 30a forms an incomplete combustion pyrolysis section by the screw part 40 and the catalyst, and the gas supplied to the additional conveying passage 30a through the gas supply part 60 is pyrolyzed at a high temperature, and the screw The shaped portion moves along the conveying passage 30a as if causing a whirlwind, and eventually the entire additional conveying passage 30a is heated to a high temperature at a uniform temperature.

Here, the temperature of the additional transfer passage 30a rises to a high temperature of about 800°C.

After forming the additional transfer passage (30a) at a high temperature, the supply of gas and oxide, which are external fuels, is cut off, and the waste is put into the hopper (H) while the motor (M) is operated to rotate the transfer unit (20). .

In addition, the intake fan 71 and the cooling fan 73 are operated to prepare for cooling the gas generated from the waste.

After the additional transfer passage 30a is formed at a high temperature, the supply of gas and oxide, which are external fuels, is cut off. The waste put into the hopper H is dropped and put into the transfer passage 10c through the inlet 10a.

When waste is put into the conveying passage 10c, the waste is transported by the screw part 40 while achieving high temperature pyrolysis (gas fication) due to the high temperature of the additional conveying passage 30a in the conveying passage 10c, and is transferred to the conveying part 20. It is discharged to the collector 90 through the outlet 10b of the.

At this time, since oxygen is generated when the waste is pyrolyzed, the amount of oxygen supplied through the oxygen supplier 100 is reduced to about 1/10 to 1/20.

For example, assuming that the amount of oxygen supplied to the first additional transfer passage 30a is 100, when the entire additional transfer passage 30a is heated to a uniform temperature at a high temperature, if the oxygen supply amount is set to about 10 to 20 do.

At this time, in order to heat the additional conveying passage 30a, a gas (LPG, methane), liquid, or fuel may be injected together with an oxidizing agent (air or oxygen) to raise the additional conveying passage 30a, which is a catalyst section, to a high temperature.

The wastes transported along the transfer passage 10c of the transfer guide 10 are pyrolyzed by incomplete combustion heat formed in the additional transfer passage 30a of the housing 30 to generate gas, and the waste gas is discharged through the discharge pipe 11. The additional is discharged to the transfer passage (30a) through.

The discharged waste gas is incompletely burned by the spark plug 80 and the oxides (air, oxygen, steam) introduced from the oxide supply unit.

That is, by the heat of incomplete combustion formed in the additional conveying passage 30a, the wastes transported along the conveying passage 10c spontaneously undergo a combustion reaction, and a part of the waste is changed into gas.

The additional conveying passage 30a forms a screw shape by the additional screw portion 50 located in the additional conveying passage 30a, so that the gas passing through the catalyst layer filled in the additional conveying passage 30a moves through the conveying guide 10. Since the whole is uniformly maintained at a high temperature and the waste can be gasified by immediately using the high-temperature heat, the length of the transfer guide 10, the transfer unit 20, and the housing 30 can be manufactured long.

In this way, when the lengths of the transfer guide 10, the transfer unit 20, and the housing 30 are manufactured long, the input amount of waste and the speed and time for gasifying the waste can be increased.

Additionally, the temperature of the transfer passage 10c may be maintained by an exothermic reaction of the waste itself. However, it is important to control the amount of air, oxygen, or water vapor so that carbon monoxide is generated rather than carbon dioxide in order to perform the exothermic reaction more efficiently.

On the other hand, syngas (Co, H2, CH4, etc.) generated by the waste gasification device 1 according to an embodiment of the present invention is cooled and separated and purified through a second catalyst device (not shown). A general process or process as shown in FIG. 5 is performed.

On the other hand, the waste gasification device 1 according to an embodiment of the present invention gasifies waste by a high-temperature pyrolysis method, and FIG. 6 shows the difference between the high-temperature pyrolysis method of the present invention and a general low-temperature pyrolysis method.

As shown in FIG. 6, it can be seen that the waste gasification device 1 according to an embodiment of the present invention using high-temperature pyrolysis does not add an external heat source cost compared to the low-temperature pyrolysis method, and the waste throughput and gasification rate are very high. can

Furthermore, it is possible to increase the filtering effect of tar, heavy metals, halogens, alkali compounds, etc. by easily installing several stages of catalysts and filter sections.

And, when waste is gasified through the waste gasification device 1 according to an embodiment of the present invention, the following effects can be exerted.

First, since there are many heat exchange sections capable of steaming H2O at a high temperature, a large amount of high-quality syngas can be produced by injecting a large amount of steam. At this time, when a large amount of steam is used as an oxidizing agent, there is an advantage in that the amount of Nox generated when using air is reduced and the cost of oxygen is reduced.

Second, since continuity (high throughput, speed) is possible, miniaturization of the product is easy.

Third, it can be treated regardless of the type and characteristics of the input waste.

Fourth, since a very small amount of oxidizing agent (oxygen) is required, the emission of carbon dioxide (CO2) is minimal.

Those skilled in the art to which the present invention pertains will understand that the present invention can be embodied in other specific forms without changing its technical spirit or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting. The scope of the present invention is indicated by the claims to be described later rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts thereof are included in the scope of the present invention. should be interpreted
