Description

Vortex Waste Incinerator {A vortex type incinerator}

The present invention relates to a vortex type waste incinerator, which is particularly simple to manufacture and assemble, and has a convex surface that minimizes thermal expansion and minimizes heat deformation, resulting in high thermal efficiency during incineration. In addition, the present invention relates to a vortex type waste incinerator, which is harmless and does not emit harmful substances and enables continuous incineration of waste.

In recent years, despite the government's efforts (garbage quota system, garbage collection, etc.) due to industrial acceleration along with the improvement of living standards, the amount of garbage has been continuously increasing, and the types are also diversifying.

Accordingly, various physical and chemical properties of wastes have been generated, and various problems (environmental pollution, transportation costs, etc.) are generated in the process of treating them, and the present situation is seeking ways for efficient management and disposal.

On the other hand, waste disposal methods can be roughly classified into landfill, recycling, and incineration. In Korea, the disposal rate of landfill accounts for a higher proportion than other methods.

Here, landfill is a method of biologically stabilizing waste, which has been widely applied in the United States, etc., but it is not only effective in the case of Korea where the land area is narrow and the opportunity for recycling waste is lost.

In response, the government is actively pursuing a policy to reduce the disposal rate by landfill while increasing the disposal rate by incineration and recycling.

However, recycling is not only economically disadvantageous, but also has a problem that the advantages of recycling itself fade due to the generation of secondary pollutants during the treatment process.

As a result, landfilling and recycling has been found to be limited in terms of environment and economics, and incineration has many advantages, such as easy disposal, small area, and no serious pollution problems.

A waste incineration device according to the prior art is shown in FIGS. 1 and 2.

As shown in Figs. 1 and 2, the prior art has a tubular combustion furnace 1 having a combustion chamber C formed therein and a flange portion 1a formed at a lower end thereof, and a lower side of the combustion furnace 1 and an upper side thereof. A waste storage container 2 in which a garbage inlet 2a is formed, a hydraulic jack 3 for raising the waste storage container 2 to be in close contact with the flange 1a, and litter in the waste storage container 2 Is disposed on the lower surface of the flange portion 1a, and the air passage W1 (hereinafter referred to as "the first air passage") is formed between the waste storage container 2 and the waste. The lower case 5 which surrounds the reservoir 2 and has an air inlet 5a formed on the lower side thereof, and is installed on the upper side of the flange portion 1a and is provided between the air passage W2 (hereinafter referred to as a combustion chamber 1). An upper case 6 surrounding the combustion furnace 1 to form a "second air passage" and an exhaust pipe 6a formed on an upper side thereof, and the air inflow; And a blowing means 7 for forcibly supplying the air introduced into the sphere 5a to the combustion chamber C through the air passages W1 and W2.

Here, the blowing means (7) is a blower (7a), the air suction pipe (7b) for connecting the upper side of the blower (7a) and the first air passage (W1), the blower (7a) and the second air passage ( It consists of the air discharge pipe 7c which connects the lower side of W2).

Meanwhile, reference numeral R, which is not described, is a guide rail, and 2b is a wheel which is installed on the lower side of the waste storage container 2 to move the waste storage container 2 along the guide rail R. The opening and closing door (not shown) provided on one side is provided to easily enter and exit the waste container (2).

And although not shown in the figure, the flange portion (1a) is provided with a gasket to maintain the airtight with the waste container (2) on the lower side.

In the prior art configured as described above, the waste storage container 2 containing the waste is raised by the hydraulic jack 3 to be in close contact with the flange portion 1a, and then the ignition means 4 is operated to light the waste and blow the blower 7a. When activated, the air introduced into the first air passage W1 by the suction action of the blower 7a absorbs the indirect heat of the waste storage container 2, is preheated first, and is sucked into the blower 7a. The air is discharged to the second air passage W2 by the discharge action of the blower 7a to absorb the indirect heat of the combustion furnace 1, preheat secondarily, and rise along the second air passage W2. The preheated air flows into the combustion chamber (C) by collision with the upper side of the upper case (6), absorbs the direct heat of the combustion chamber (C), preheats it to high temperature, and lowers it to the waste storage container (2) for complete combustion of garbage. It is raised, smoked, and discharged to the outside through the exhaust pipe 6a.

However, the prior art constructed and operated as described above has the following problems.

① The case is divided into a lower case 5 and an upper case 6, and has a waste storage container 2 and a combustion furnace 1 inside thereof. .

② Since the wall of the furnace 1 is formed to be flat, the thermal expansion is large, so that the shape may be deformed or cracks may occur due to the heat of 1,800 to 2,000 ° C. in the combustion chamber C for a long time. Strength becomes weak.

③ The preheated air discharged into the second air passage W2 rises by forming a vortex flowing through the inner wall of the upper case 6 by the blowing action of the blower 7a, and the preheated air introduced into the combustion chamber C Due to the centrifugal force due to the vortex phenomenon, the vortex flowing through the inner wall of the combustion furnace 1 forms and flows down, and the wall of the upper case 6 and the combustion furnace 1 is formed to be flat so that vortex formation of preheated air is actively It is not possible to achieve smoother and faster airflow.

④ When the temperature of the combustion chamber (C) is excessively increased due to the preheated air flowing into the combustion chamber (C) through the air passage (W1) (W2) there is no way to simply and quickly lower the temperature, thereby the problem of ② This weighting is self-evident.

⑤ Since the preheated air rising through the second air passage (W2) is simply configured to change the flow direction and flow into the combustion chamber (C) due to the collision with the upper side of the upper case (6), some of the preheated air It is not possible to achieve the redirection and is immediately discharged through the flue pipe (6a) can not expect higher thermal efficiency.

⑥ Because of the problem of ⑤ above, high thermal efficiency cannot be expected. Hazardous substances such as carbon dust or dioxin, which are incompletely burned through the flue pipe 6a, are emitted, resulting in environmental pollution.

⑦ In order to inject waste into the waste storage container (2), the hydraulic jack (3) is operated to lower the waste storage container (2), release the contact with the flange portion (1a), and put the waste in close contact after the repeated operation of the frequent Therefore, not only the contact surface between the flange portion 1a and the waste storage container 2 is easily damaged or broken, but also the gasket between the two is damaged or broken together, resulting in an unexpected leakage of combustion gas.

⑧ Since the waste can be put into the waste storage container (2) only by performing the same process as the above ⑦, it is impossible to put the waste into the waste storage container (2) during the incineration operation, so the incineration efficiency is reduced.

The present invention is to solve the above problems of the prior art, the structure is simple by integrating the lower case and the upper case, the waste storage container and the combustion furnace, respectively, and formed in a coil shape so as to convex the wall of the case and the combustion furnace thermal expansion Not only this but also an object of the present invention is to provide a vortex type waste incineration apparatus which can actively form the vortex formation of the air due to the blowing action of the blowing means.

It is another object of the present invention to provide a vortex type waste incineration apparatus which is configured to directly blow external air so as to supply external air to the combustion chamber so that the temperature in the combustion chamber can be easily and quickly adjusted.

Still another object of the present invention is to provide a vortex type waste incinerator having high heat efficiency due to low heat loss by providing a guide means for guiding preheated air rising through the second air passage to the combustion chamber.

Another object of the present invention is to provide a vortex type waste incineration device that prevents accidental discharge of hazardous substances through the exhaust pipe by installing air nozzles on the exhaust pipe and injecting air to achieve complete combustion of the incomplete combustion material. There is.

Another object of the present invention is to provide a waste supply means for directly inputting garbage from the outside, so that there is no damage or damage to the components due to the detachment process, as well as vortex type waste which can continuously inject and incinerate the waste. To provide an incinerator.

Figure 3 is a cross-sectional view showing the overall configuration of the vortex type waste incineration apparatus according to the present invention, Figure 4 is a perspective view showing the shape of the incinerator of Figure 3 in detail.

3 and 4, the present invention is formed in a vertical cylindrical shape up and down to wrap the waste in the incinerator 10 and the incinerator 10, the air passage (W1) (W2) is formed between the incinerator (10) The case 20, the ignition means 30 for igniting the waste of the incinerator 10, and the air passages W1 and W2 are divided up and down, and the first air passage W1 is disposed upward. The partition 40 which forms the 2nd air path W2, and the blowing means 50 which supplies the air of the said 1st air path W1 to the inside of the incinerator 10 through the 2nd air path W2. And, guide means 60 for guiding the air provided by the blowing means 50 to be efficiently supplied to the incinerator 10, and injecting air toward the smoke discharged to the outside to incomplete combustion material in the smoke With the air nozzle 70 to combust and the waste supply means 80 which can supply waste to the waste storage chamber 12 from the outside. It is.

In the present invention configured as described above, the incinerator 10 and the case 20 are coiled embossing portions 11 and 21 wound around the inner wall in a spiral shape along a longitudinal direction, respectively. (The shape reference and case of the incinerator shown in FIG. 4 are similarly formed.)

The embossing part (11) (21) is embossed by the embossing part (11) (21) of the air supplied into the incinerator 10 through the second air passage (W2) by the blowing action of the blowing means (50) Along the spiral valleys 11 'and 21' formed between the portions 11 and 21, the natural flow forms a vortex and smooths the flow itself.

In addition, due to its convex shape, the thermal expansion of the incinerator 10 is minimized due to heat so that the heat resistance of the incinerator 10 is also excellent.

The embossing parts 11 and 21 are formed only on the inner wall of the incinerator 10, while only the parts necessary for forming the second air passage W2 are formed on the inner wall of the case 20. However, the present invention is not limited thereto, but may be formed together with a portion necessary for forming the first air passage W1.

The incinerator 10 has a waste storage chamber 12, which is a space in which waste is stored, and a combustion chamber 13, which is a space in which waste is burned, is formed above the waste storage chamber 12.

In addition, an open air inlet 14 is formed at an upper side thereof so that air supplied from the blowing means 10 can enter and exit the combustion chamber 13.

The case 20 has an air inlet 22 formed at the lower side to allow external air to flow into the air passages W1 and W2, and the smoke generated during the combustion of the combustion chamber 13 at the upper side is an air inlet. The exhaust pipe 23 is formed to be discharged to the outside through the (14).

Therefore, the external air introduced into the air passages W1 and W2 through the air inlet 22 is preheated by the heat of the waste storage chamber 12 and the combustion chamber 13 during the passage of the air passages W1 and W2. After this is made to flow into the combustion chamber 13 to help the combustion is discharged to the outside through the exhaust pipe (23).

Although not specifically illustrated in the drawing, the ignition means 30 may be used as long as it can light the garbage. For example, a gas burner ignited by a flame rising toward the garbage may be used.

The blowing means 50 causes the flow of air to suck the air introduced into the first air passage (W1) through the air inlet (22), and discharge it to the second air passage (W2) to achieve complete combustion of the waste do.

The blowing means 50 is a blower 51 consisting of a casing and an impeller built in the casing, and the blower 51 and the first so that the blower 51 can suck the air of the first air passage (W1) The air inlet pipe 52 connecting the air passage W1 and the blower 51 and the second air passage W2 are configured to discharge the air sucked by the blower 51 into the second air passage W2. An air discharge pipe 53 to be connected, an air suction pipe 54 installed in the air suction pipe 52 to directly suck external air of the blower 51, and an air suction pipe of the air suction pipe 52 ( 54) It consists of a 3-way valve 55 installed at the branch.

Here, the air suction pipe 52 has one end connected to the upper side of the first air passage W1, and the air discharge tube 53 is connected so that one end passes through the lower side of the second air passage W2. And close to 40).

In addition, the three-way valve 55 is to allow the blower 51 to suck the entire amount of air or external air introduced into the first air passage W1 or to mix and mix both of them. The purpose of the present invention is to prevent external air having a lower temperature than preheated air preheated through the first air passage W1 into the combustion chamber 13 and excessively increasing the temperature of the combustion chamber 13.

In other words, it is to control the temperature of the combustion chamber 13 and to maintain it at an appropriate temperature at all times.

At this time, the three-way valve 55 may be manually operated or vice versa automatically. If the automatic operation is desired, a temperature sensor for sensing the temperature of the combustion chamber 13 and a signal from the temperature sensor are received. Of course, it should be provided with a control unit for controlling the operation of the three-way valve (55).

On the other hand, the blowing means 50 may increase the number of installation according to the blowing capacity required, unlike in the figure.

The guide means 60 is installed inside the upper portion of the case 20 to prevent the air flowing from the second air passage (W2) to the combustion chamber 13 to immediately flow into the exhaust pipe 23, and to be discharged to the outside As guided to the combustion chamber 13, it consists of the air discharge prevention part 61 and the air guide plate 62 roughly.

First, the air discharge preventing part 61 extends from the lower end of the exhaust pipe 23 toward the air inlet 14 so that air flowing from the second air passage W2 to the combustion chamber 13 is exhausted. (23) is prevented from entering.

At this time, the air discharge preventing portion 61 is formed in the same shape as the exhaust pipe 23, the end of the air outlet 14 is preferably formed in a length that can be located on the same line.

Next, the air guide plate 62 converts the air flow direction of the second air passage W2 toward the combustion chamber 13 by 180 degrees, and is formed in an upper convex arc shape to surround the air discharge preventing part 61. Is installed.

Here, the air guide plate 62 may be formed in a ring shape so as to be fitted around the air discharge preventing unit 61, and divided into a plurality of air guide plates 62 at predetermined intervals around the air discharge preventing unit 61, respectively. You can also place it.

The air nozzle 70 is installed to the lower side of the exhaust pipe 23 so that the end toward the center of the exhaust pipe 23 so that the air can be injected into the smoke discharged through the exhaust pipe 23, the circumference Many are arranged along the direction to inject air at regular intervals.

At this time, the air nozzle 70 is specifically installed in the air discharge prevention portion 61 extending from the exhaust pipe 23 so that its end is directed to about 45 upward.

Like the three-way valve 55, the air nozzle 70 can be operated manually or automatically by a control unit.

The waste supply means 80 is provided for the purpose of simply and quickly supplying and incinerating waste to the waste storage chamber 12 even during the incineration operation, a waste injecting hopper 81 installed outside, and the waste injecting hopper ( A waste transfer drum 82 connected to the lower side of the waste container 81 through the waste storage chamber 12 and the waste introduced into the waste input hopper 81 are installed in the waste transfer drum 82 and the waste storage chamber 12. The waste conveying screw 83 to be transferred to, and the drive means 84, that is, the driving motor for providing power for rotating the waste conveying screw 83.

Reference numeral 15, which is not described above, is a check opening for checking the state of the inside from the outside, and 16 is a cap covering the inlet of the check opening (15).

Figure 5a is a cross-sectional view showing the air flow during the incineration operation of the vortex type waste incineration apparatus according to the present invention, referring to the operation of the present invention configured as described above with reference to this.

First, the driving means 84 is operated to rotate the waste conveying screw 83, and the waste is introduced into the waste moving drum 82 through the waste injecting hopper 81.

At this time, the waste is gradually transported to the waste storage chamber 12 by the driving force of the waste transport screw 83 is collected in the waste storage chamber 12.

Next, when the amount of garbage corresponding to the proper capacity is collected in the waste storage chamber 12, the driving means 84 is stopped, the ignition means 30 is operated to light the garbage, and then the three-way valve 55 is operated. The air intake pipe 52 is opened at the same time as the outside air intake pipe 54 is closed, and the blower 51 is operated at high speed and high pressure.

Therefore, when the blower 51 is operated, the air introduced into the first air passage W1 through the air inlet 22 absorbs the indirect heat of the waste storage chamber 12 by the action of the blower 51, and the incinerator 10 At the same time as the wall is cooled, it is first preheated and sucked into the blower 51 through the air suction pipe 52.

The sucked preheated air is discharged to the second air passage W2 through the air discharge pipe 53 by the blowing action of the blower 51, and the discharged preheated air absorbs the indirect heat of the combustion chamber 13, and incinerators ( 10) At the same time as cooling the wall surface of the secondary preheating and rises along the second air passage (W2).

At this time, the preheating air that rises forms a vortex that flows through the inner wall of the case 20 by the blowing action of the blower 51, and the ribs are formed by the coil-shaped embossing part 21 of the case 20. 21 ') flows naturally up and rises.

Then, the rising preheating air is blocked by the upper side of the case 20, and when it cannot rise any more, it collides with the air guide plate 62, and naturally flows toward the air inlet 14 along the curved surface of the air guide plate 62. After switching to the combustion chamber 13, the preheated air that did not change the direction impinge on the secondary air discharge prevention portion 61 to switch the direction toward the air inlet (14).

At this time, the rising preheated air is blocked by the air discharge prevention unit 61 and is guided by the air guide plate 62, so that the total amount of the air flows into the combustion chamber 13.

Next, the preheated air introduced into the combustion chamber 13 absorbs the direct heat of the combustion chamber 13, cools the wall surface of the incinerator 10, and is preheated to the third temperature to become high temperature, and descends toward the waste storage chamber 12.

At this time, the preheating air descends toward the waste storage chamber 12 by forming a vortex flowing through the inner wall of the incinerator 10 by centrifugal force due to the vortex phenomenon, which is likewise the embossed part 11 of the incinerator 10. By naturally flowing down the wall surface of the incinerator (10).

Then, the preheated air is introduced into the waste storage chamber 12, mixed with the waste, completely burned, and then smoked to rise through the center portion of the incinerator 10.

At this time, the heat reaching 1,800-2,000 ° C. is generated, and the incinerator 10 minimizes deformation or cracking due to its excellent heat resistance by the embossing portion 11.

The next rising smoke is introduced into the exhaust pipe 23 through the air inlet 14 and then discharged to the outside through the exhaust pipe 23.

At this time, the incomplete combustion material contained in the high-temperature smoke is discharged in a harmless state by the secondary air combustion by the injection air of the air nozzle 70 which periodically performs the injection operation.

On the other hand, when the incineration of the waste is partially completed and the waste is to be put into the waste storage chamber 12, the driving means 81 is operated, the waste conveying screw 83 is rotated, and the waste is immediately put into the waste injecting hopper 81. do.

At this time, the waste is naturally dried in the waste transfer drum 82 by indirect heat of the waste storage chamber 12 and then transferred.

On the other hand, if the temperature of the combustion chamber 13 is excessively increased while the above process is repeatedly operated, it is necessary to close the air intake pipe 52 by operating the three-way valve 55 as shown in FIG. At the same time, the open air suction pipe 54 is opened.

Therefore, only the pure external air, not the primary preheating air, is sucked into the blower 51 through the outside air suction pipe 54, and the sucked external air flows into the combustion chamber 13 through the second air passage W2, and the combustion chamber Lower the temperature of (13).

At this time, the incinerator 10 is lowered in the temperature of the combustion chamber 13 to further prevent deformation or cracking of the wall surface.

The present invention constructed and operated as described above has the following effects.

First, since the waste storage chamber and the combustion chamber are formed in the incinerator, respectively, and are composed of a structure surrounding the case, the structure is simple, and thus manufacturing and assembly can be easily and easily performed.

Second, since the embossed portion is formed on the wall surface of the incinerator, it is excellent in heat resistance, thereby minimizing the occurrence of deformation or cracking of the incinerator by heat reaching 1,800-2,000 ° C. in the combustion chamber.

Thirdly, by the blowing means having a three-way valve for opening and closing the outside air suction pipe and the outside air suction pipe, the outside air can be sucked in and supplied to the combustion chamber, so that the temperature of the combustion chamber can be controlled, and thus the temperature of the combustion chamber is excessively increased. You can prevent it.

As a result, the deformation or cracking of the incinerator together with the embossing part can be prevented more actively.

Fourth, as the blower forms a vortex into the combustion chamber through the air passage, the natural air flow is possible due to the valleys formed by the coil-type embossing part of the case and the incinerator, so that the vortex formation of air can be actively promoted. It can provide smooth and fast airflow.

Therefore, it is possible to maximize the complete combustion of garbage as well as firepower.

Fifth, since the air introduced into the combustion chamber by the guide means is guided to the combustion chamber while preventing the discharge into the flue pipe, heat loss can be minimized and high thermal efficiency can be expected.

Of course, this also maximizes the complete combustion of waste, just like the embossing section.

Sixth, even if incomplete combustion material is unexpectedly introduced into the flue pipe, the secondary combustion of the incomplete combustion material by the air injected from the air nozzle prevents its emission itself, thereby preventing environmental pollution.

Seventh, it is possible to incinerate waste efficiently because the waste supply means can continuously input waste.

Therefore, as in the prior art, not only a cumbersome detachment process for injecting waste is necessary, but also there is no damage or breakage of components inevitably generated during frequent detachment processes, thereby prolonging its life.
