Description

Combustion apparatus using waste synthetic resin as fuel {TH BURNING APPARATUS USING USELESS PLASTIC}

The present invention relates to a combustion apparatus for burning waste synthetic resin.

In the modern industrial society in which various products made from synthetic resins are inundated, the disposal of waste synthetic resins is a big social problem.

Although recycled synthetic resin products are recycled into various injection molded products, the capacity for recycling is much smaller than that of the collected synthetic resin, which has a limited use and processing capacity, and many of them cannot be recycled. Because it is relatively expensive.

Meanwhile, in the era of high oil prices, various industries are required to save oil.

As described above, various technologies have been developed to enable the use of waste synthetic resins as fuel by heating using heat generated when burning the waste synthetic resins.

Specifically, Korean Utility Model Registration No. 0263150, "Communication multi-stage combustion device with automatic feeder" (filed Nov. 14, 2001) and the like.

However, when the waste synthetic resin is burned using the conventional method, since the gelled waste resin is entangled in the supply portion of the combustion chamber and is not easily burned, it takes a long time to burn and there is a problem that the waste synthetic resin cannot be continuously supplied.

In addition, the combustion temperature is low, there was also a problem that various pollutants are mixed with the exhaust gas and discharged as it is.

The object of the present invention is to provide a combustion apparatus using waste synthetic resin having excellent combustion efficiency as fuel is burned at a high temperature at the same time as the burned synthetic resin gelled by high heat does not occur.

In addition, the purpose is to allow the flame generated during the combustion of the waste synthetic resin to be burned at a higher temperature while forming a whirlwind so that a faster combustion occurs and the amount of pollutants is reduced.

In addition, by injecting ozone with oxygen in the combustion chamber to combust at a higher temperature, the combustion is faster, and at the same time, there is also an object to maximize the effect of reducing the pollutants.

The present invention relates to a combustion apparatus using waste synthetic resin as fuel.

In the present invention, the combustion burner which is gradually lowered toward the rotation center is positioned in the combustion chamber and the combustion object is landed on the edge while rotating, so that the waste synthetic resin gelled by the high heat flows from the edge of the combustion burner to the rotation center gradually and then on the combustion burner. Thin and evenly distributed, smooth combustion is achieved.

Therefore, the combustion device using the waste synthetic resin of the present invention as a fuel,

A housing having a combustion chamber for combustion of the waste synthetic resin, the housing being an appearance of the combustion apparatus;

Synthetic resin supply means for supplying waste synthetic resin, which is a combustion object, to the combustion chamber;

Has an ignition device for combustion.

In addition, the combustion burner is located in the combustion chamber and rotated, the upper surface is lowered step by step toward the rotation center portion, the waste synthetic resin gelled by the high heat flows from the edge to the rotation center portion is thin and evenly distributed on the upper surface.

In addition, oxygen supply means for supplying oxygen for combustion in the combustion chamber;

Has a communication in which the gas generated during combustion is discharged.

Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

However, since the accompanying drawings are only examples illustrated to more specifically describe the technical idea of the present invention, the technical idea of the present invention is not limited to the form of the accompanying drawings.

The present invention relates to a combustion apparatus of waste synthetic resin.

Therefore, as in the conventional waste synthetic resin combustion apparatus, it has the combustion chamber 11 for combustion, and has the housing 10 which forms the external appearance of a combustion apparatus.

It also has an ignition device 20 for combustion and oxygen supply means 30 for supplying oxygen for combustion into the combustion chamber 11.

In addition, it has a communication (40) through which the gas generated during combustion is discharged and a synthetic resin supply means (50) for supplying the waste synthetic resin, which is a combustion object, to the combustion chamber (11).

The housing 10, the ignition device 20, the communication 40, the oxygen supply means 30, the synthetic resin supply means 50 may be implemented in the form as usual.

However, the combustion of the waste synthetic resin is not smooth through the conventional method.

Specifically, the combustion of the synthetic resin is made through the process of liquefaction-pyrolysis-gasification.

Therefore, when heat is applied to the waste synthetic resin, the gel is subjected to a process of gelation. The waste synthetic resin in the gel state is strongly entangled, and thus the supply is not smooth.

That is, when the waste synthetic resin is put into the combustion chamber 11, the waste synthetic resin does not flow largely at the landed position in the combustion chamber 11 and is entangled and accumulated so that the combustion is not smooth and the waste synthetic resin cannot be continuously supplied quickly. It is followed.

Due to this problem, the waste synthetic resin could not be used as fuel for combustion.

Therefore, in order to fuel waste synthetic resins, the gelled waste synthetic resins should be prevented from accumulating so as to be able to be burned at a high temperature through a smooth combustion as well as to enable continuous supply.

In the present invention, the combustion burner 60 rotated in the combustion chamber 11 is positioned to prevent the waste synthetic resin supplied from a specific position from stagnating at the landing point.

In addition, the upper portion of the combustion burner 60 is lowered stepwise toward the rotation center, so that the waste synthetic resin gelled by the high heat drops and rotates at the edge of the combustion burner 60 and gradually flows to the rotation center to be thin and even on the upper surface. Distributed, thereby allowing smooth combustion.

The configuration for the rotation of the combustion burner 60 may be implemented in the form of rotating the shaft 61 connected to the rotation center of the combustion burner 60 through the reducer 62 as shown in FIG. 1.

With only the above configuration, it is possible to supply the waste synthetic resin smoothly and smoothly burn it.

However, in order to remove contaminants generated during the combustion of the waste synthetic resin, the waste synthetic resin is required to be burned at a higher temperature while burning more smoothly, and a technique for completely burning the combustion residence time is increased.

As a method for this purpose, there is a method in which the oxygen supplied into the combustion chamber is injected and supplied to rotate in the combustion chamber as a whole to increase the combustion residence time as the flame is burned while forming a whirlwind and to burn at a high temperature.

As a specific configuration, there is a method of forming a tornado through oxygen supplied through the oxygen supply means 30 as shown in FIGS. 1 and 2.

The oxygen supply means 30 of FIG. 1 and FIG. 2 includes a source oxygen supply device 31 and a tornado oxygen supply device 32.

As shown in FIGS. 3 and 4, a plurality of nozzles 31a are installed at each step of the upper surface of the combustion burner 60, and nozzles are arranged in a circular structure on the same step. The oxygen is sprayed in the direction so as to be sprayed in a circle as a whole.

In addition, the whirlwind forming oxygen supply device 32 injects high-pressure oxygen at the upper end of the flame burned by the combustion burner 60, but the nozzle 31a of the source oxygen supply device 31 injects oxygen. Spray in the same direction as to form a whirlwind in the flame.

More specifically, as shown in FIG. 5, the high-pressure compressed air supplied from one side proceeds along a circular curved pipe, and is sprayed through an injection hole 32a formed at an angle to the pipe to form a tornado.

That is, in the vicinity of the upper surface of the combustion burner 60 on which the waste synthetic resin is landed, oxygen for smooth combustion is supplied at a relatively low speed, but oxygen injected from the nozzle in one direction only forms a whirlwind in the combustion chamber 11. In this way, the oxygen supplied to the upper surface of the combustion burner 60 in this manner is relatively low, so it is somewhat insufficient to form a whirlwind, so that a strong whirlwind is formed in the upper and middle portions of the flame to form a strong whirlwind.

By the above configuration, since the waste synthetic resin is burned while maintaining a very high temperature in the combustion chamber 11, the amount of pollutants discharged through the gas can be greatly reduced.

However, when the ozone generated through the ozone generator 71 is supplied to the combustion chamber 11 together with oxygen, combustion occurs at a higher temperature, and the amount of pollutants is further reduced.

The ozone supply device 70 may be implemented in various forms to connect the pipe through which the ozone generated from the ozone generator 71 flows to the oxygen supply means 30 described above.

In addition, as shown in Figs. 1 and 2, the mixture is injected with oxygen at the center of the flame, and the nozzles 72 are arranged in a spiral structure, and oxygen and ozone are injected along the helical direction to form whirlwind in the flame. It can also be supplied.

According to such a configuration, the tornado is more powerful and the ozone is also supplied smoothly, so that the waste synthetic resin can be burned at a high temperature of 1000 ° C. or more, and the emission of pollutants is extremely small.

In this case, when the combustion temperature is very high, problems such as gelation and ignition occur during the feeding process before the synthetic resin is introduced into the combustion chamber 11, so that the cooling device 53 is supplied to the synthetic resin supply means 50 for smooth supply of the synthetic resin. It is preferable to have a.

In addition, the synthetic resin supply means 50 is preferably to be able to inject the pulverized waste synthetic resin to the edge of the combustion burner 60 through a screw conveyor.

Referring to the operation of the present invention using the accompanying drawings as follows.

Combustion chamber 11 of the present invention shown in Figure 1 is a double castable and the heat insulating material is filled in the outer wall thick enough to withstand high temperatures.

Before the waste synthetic resin is supplied, the ignition device 20 is operated to heat the combustion chamber 11. Like the ignition device 20 provided in the conventional synthetic resin combustion device, the ignition device 20 of the present invention is also the combustion chamber 11. Fire the flame until the temperature inside is about 450 ℃, and stop automatically when it reaches about 450 ℃.

When the waste synthetic resin is supplied through the synthetic resin supply means 50, the combustion burner 60 is already rotated, but the combustion burner 60 gradually decreases in a stepped manner toward the center of rotation, so that the fuel inside the combustion chamber 11 Liquefaction-pyrolysis-gasification can facilitate the combustion process can be continuously supplied to the combustion burner 60 a large amount of waste synthetic resin.

The rotation of the combustion burner 60 is connected to the shaft 61 formed at the rotational center of the combustion burner 60 by the chain and rotated at a speed of about 0.3 rpm in accordance with the rotation of the speed reducer 62. do.

The waste synthetic resin injected into the combustion chamber 11 is ignited at the upper end of the combustion burner 60, and the waste synthetic resin ignited when oxygen is injected through the nozzle 31a formed at the upper end of the combustion burner 60 among the oxygen supply means 30. Combustion becomes more active.

In addition, when oxygen is injected through the whirlwind forming oxygen supply device 32 formed at the upper end of the flame to be burned, a whirlwind is formed in the combustion chamber 11 and the flame causes the whirlwind to be burned.

The synthetic resin supply means 50 and the combustion chamber 11 is burned while the whirlwind is formed to reduce the emission of nitrogen oxides (NOx) regenerated by the high temperature, the combustion residence time is long, the heat energy generated during combustion Is to heat the water outside the combustion chamber (11).

When ozone is injected through the ozone generator 71, the waste synthetic resin is completely burned by burning at a high temperature of 1000 ° C. or more, and contaminants such as nitrogen oxides are greatly reduced.

In FIG. 1, the nozzles 72 of the ozone generator 71 are arranged in a spiral structure and sprayed in four directions, thereby forming a strong whirlwind.

A small amount of ash generated by the combustion is displaced to the outside of the combustion chamber 11 due to the whirlwind phenomenon in the combustion chamber 11 and is discharged to the bottom by falling between the iron rod hooks which are formed on the outside of the combustion burner 60 in a straight line. do.

Exhaust gas is discharged to the outside through the communication (40), the fine dust mixed in the exhaust gas is collected by the cyclone (80), the middle of the communication 40 is equipped with a blower ejector nozzle 90 in the combustion chamber ( 11) The inside becomes negative pressure (-).

The completely burned high-temperature clean gas is converted into steam or hot water energy while heating the boiler's heating surface by very high heat diffusion, and is used for industrial or rural fishing facilities.

The present invention can be applied to a boiler such that heat generated during combustion heats water.

In addition, it is also possible to heat the greenhouse or the plastic house using the exhaust gas discharged through the communication.

In other words, the heat generated by burning the waste synthetic resin is used for heating to recover the heat due to the combustion of the waste synthetic resin.

Reference numeral 16 is an association in which gas in the combustion chamber 11 is discharged, and 100 is water heated by heat generated in the combustion chamber.

The waste synthetic resin combustor of the present invention, as the combustion burner is rotated and gradually lowers stepwise as it goes to the center of rotation, not only does the waste synthetic resin get tangled at a specific position, but also the liquefaction-pyrolysis-gasification process of the waste synthetic resin is fast. By doing so, stable and fast combustion is achieved.

Therefore, since the waste synthetic resin can be continuously supplied, it is possible to fuel the waste synthetic resin.

In addition, if the whirlwind is formed in the flame generated when the waste synthetic resin is burned, more smooth combustion occurs, and when it is supplied to ozone (O³), it is completely burned to reduce the pollutants. Can be.
