Description

The Advanced Trash Burner

Incineration burners that can incinerate incineration efficiency in incineration of organic solids, combustible liquids, mixed organic and inorganic wastes, induce complete combustion, recycle the generated heat source to energy, and automatically coagulate combustion residues. More particularly, it relates to a rotary incineration burner capable of recycling the resources for the heat source generated by the incinerator, which solves the problem of environmental pollution to industrial waste and enables complete combustion.

Conventional incineration burners are provided with a dry distillation burner, and the dry distillation burner is used to separate volatile and nonvolatile substances by heating solid organic matter such as coal or wood into a non-air flow mechanism, or to remove coal gas and tar from coal. For example, it was commonly used to obtain coke or charcoal from wood.

In addition, it is common to expand the inside of the combustion chamber housing in order to increase the surface area of the burner in order to improve vaporization and reaction with oxygen, but this increases the efficiency of the installation space and loss of thermal energy by increasing the size of the overall equipment. I have a problem.

In addition, the surface area of the combustion chamber housing is constant depending on the volume, thereby limiting the processing capacity of the incinerated object per unit area, and when the excess capacity exceeds the processing capacity, the efficiency of the incinerator is not fully burned and the efficiency is further reduced. The incinerator was not very efficient in terms of size and cost, due to the difficulty in distributing and controlling the gas and maximizing the surface area compared to the combustion chamber volume and the lack of technical knowledge on turbulence.

Conventional burners require that the injected solid fuel particles have a high reach and that the injected fuel must be uniformly distributed throughout the space in the combustion chamber housing. However, the conventional burner has a single injection nozzle and is uniform in the housing. There is a problem that distribution is difficult to achieve.

In addition, in order to dispose of the residual residue after combustion, the process of stopping the ignition of the burner periodically and cleaning the interior or separating and collecting the residue is repeated to reduce the efficiency of the equipment and the efficiency of the operator. There is a problem that the overall utility over time is poor.

The present invention has been made to solve the above problems and to provide an incineration burner for more efficient and maximized effect, the applicant has already overcome the problems of the prior art, Korean Patent Registration No. 0845411 (Invention: Solid fuel dry distillation burners).

The present invention further improves the prior art, and provides an improved incineration burner having a structure that can effectively induce complete combustion and further maximize the efficiency of the easy collection of combustion residues and the burner scale.

Accordingly, the present invention provides a structure for maximizing the image area to the inner surface area compared to the volume of the combustion chamber, forming turbulence in the combustion chamber during combustion of the burned object to increase the complete combustion, and to control the temperature and combustion progress rate of the combustion chamber. It aims at the technical features to increase the complete combustion and combustion efficiency.

In addition, the present invention is to implement a combustion chamber consisting of a rotating body and a structure that can control the flow rate of the combustion gas in the combustion chamber so that the effective collection and treatment of combustion residues and complete combustion of unburned gas can be achieved. It is.

The present invention has no leakage of air supplied to activate combustion, can easily supply the incineration to the combustion chamber, it is possible to easily monitor and control the process including the temperature and flow rate, While significantly reducing the scale, it minimizes heat loss to the outside of the combustion chamber, and the combustion gas temperature can be maintained at a constant high temperature while preventing damage such as thermal deformation or breakage of the combustion chamber exhaust port due to high temperature melting.

In addition, it is possible to maintain the spontaneous ignition temperature of the object to be burned, and by providing a special projecting wall structure that forms a turbulent flow in the combustion gas, it is possible to maximize the amount of incineration per area compared to the general cylindrical combustion chamber by increasing the heat transfer area.

Therefore, the present invention conserves water quality and ecosystems from the problems of water quality and aquatic ecosystem pollution that may occur when industrial wastes are buried underground, and prevents air pollution generated by a conventional incinerator by a complete combustion facility. It can be used as a facility to promote waste disposal and resource saving and recycling.

The residue removal chamber 250 provided between the primary combustion chamber 240 and the secondary combustion chamber 260 should have a reduced flow rate so that unburned residues such as inorganic materials can be loaded after combustion is performed in the primary combustion chamber 240. do.

If the combustion gas flow rate inside the combustion chamber is fast, the residue may not be loaded and may be scattered to the exhaust port 300.

Therefore, the Bernoulli principle has been applied to the primary combustion chamber, which is provided in a tapered form in which the inner diameter is gradually expanded to lower the flow rate.

In addition, the residue removing chamber 250 is provided in a cylindrical shape, and a coagulation jaw 213 is provided at a portion entering the secondary combustion chamber 260 so that the residue is accumulated in the coagulation jaw 213.

The accumulated residues are rotated according to the rotation of the combustion chamber when the residue guide grooves 212 provided on one surface of the agglomeration jaw 213 are positioned below the combustion chamber, and the accumulated residues are poured into the residue guidance grooves 212 and the combustion chamber. Since the rotation continues to the outside of the combustion chamber and the extended collection pipe 210 along the residue guide groove 212, when the end of the collection pipe reaches a predetermined position during rotation may be discharged and collected.

Figure 4 is a perspective view showing the secondary combustion chamber structure of the incineration burner according to the present invention, the residue remaining in the collection pipe 210 can be flowed back during rotation, preventing the back flow of the residue inside the collection pipe 210 A blocking plate 211 is provided.

In addition, a secondary air supply nozzle 310 is provided on the inner wall of the secondary combustion chamber so that the injection guide port 311 is formed to protrude at regular intervals to inject air.

The secondary air supply nozzle 310 prevents damage due to heat melting of the secondary combustion chamber and maintains the combustion chamber temperature at 1200 ° C to 1300 ° C to reduce nitrogen oxide (NOx) emissions that worsen air quality. It has the feature of implementing a NOx gas burner.

To this end, one side of the supply nozzle 310 is connected to the secondary air passage box 126, and has an injection guide port 311 open toward the exhaust port 300 along the inclined surface of the secondary combustion chamber 260.

The injection guide port 311 is not in close contact with the inner wall of the secondary combustion chamber 260, but is spaced apart by a predetermined interval, and is fitted on an extended virtual extension line of the inclined injection guide port 311. The inclination is maintained with the supply nozzle 310 such that the focal point is located behind the exhaust port 300.

When the focal point formed by the virtual extension line is formed in the exhaust port 300, a phenomenon may occur in which an air curtain is generated to make it difficult to efficiently discharge the heat source by the combustion gas to the exhaust port 300.

In addition, when the injection guide hole 311 is multi-array, the interference between the front and rear injection guide 311 may occur, it should be designed in consideration of the arrangement pattern.

Preferably, the arrangement is arranged so as not to be located on the same line with each other in the front and rear heat arrangement.

Preferably, when the arrangement and quantity of the injection guide port 311 and the inclination angle of the secondary combustion chamber 260 are supplied to the secondary combustion chamber 260 when the combustion gas that has maintained a flow rate of 0.5 m / sec or less is unburned, In order to completely burn it, the secondary air is injected at a high speed of 30 m / sec or more to supply the air required for combustion.

7 to 9 is a view showing a form for each orientation of the incineration burner according to the present invention, in Figure 7 the operator through the supply pipe (122) consisting of a transparent window mounted to the fixing portion cover 120 ( The state of inflow into the combustion chamber of the incinerated object supplied through 119 may be constantly checked, and the combustion state in the combustion chamber may be visually checked through the combustion chamber sight hole 125.

In addition, a plurality of heat dissipation holes 320 are provided in FIG. 8 corresponding to the rear part so that the air supplied to the secondary air passage box 126 may be exhausted around the exhaust port 300.

The heat dissipation hole 320 determines the diameter and the number of ground air so that the air pressure set in the secondary combustion chamber can be injected.

That is, the larger the total area of the heat dissipation hole 320, the lower the pressure in the secondary air passage box 126, which is proportional to the pressure in the injection guide port 311.

In addition, when the total area of the heat dissipation hole 320 is configured too narrow, this increases the pressure inside the secondary air passage box 126 as well as the temperature of the combustion chamber outer wall 227 due to the temperature transmitted from the combustion chamber, so that the heat insulation Performance may be degraded.

Therefore, it is preferable to implement this by adjusting it appropriately, and it may be possible to recycle the hot air exhausted through the heat dissipation hole 320.

As described above, the present invention preserves the water quality and ecosystem from the problems of water quality and aquatic ecosystem pollution that may occur when industrial wastes are buried underground, and the air pollution generated by the conventional incinerator is completely transferred to the combustion facility. It can be used as a facility to prevent waste, and to promote waste disposal and resource saving and recycling.
