Therefore, the development of mobile incinerators that can be disposed of in the area and the waste generated in the area is urgently required, and research and development are also actively progressing.

On the other hand, the existing incinerator including a mobile incinerator has a fatal disadvantage that too much fuel consumption due to the high temperature heat supply.

In particular, a high enough concentration of oxygen necessary for combustion is not smoothly supplied, so the combustion efficiency is not so high, and thus there is a problem that harmful toxic gases are emitted.

In addition, foreign incineration equipment is inadequate to dispose of wet Korean waste and its price is very expensive.

Therefore, there is an urgent need for the development of an environment-friendly incinerator that is suitable for waste incineration in Korea, is inexpensive, saves more energy, and minimizes the emission of toxic gases.

In order to achieve the above object of the present invention, the incinerator according to the present invention includes at least one combustion chamber for burning the incineration. The combustion chamber is provided with a burner for providing combustion heat. The burner is powered by the generator. On the other hand, a dust collecting filter is connected to the combustion chamber so that the combustion products are collected by the dust collecting filter and then cooled.

The inner wall of the combustion chamber is provided with a thermoelectric element for converting the waste heat generated during combustion into electrical energy. The inner wall of the thermoelectric element is provided with a heating element that receives the electrical energy from the thermoelectric element is converted into thermal energy and provided into the combustion chamber.

On the other hand, the combustion chamber is divided into primary and secondary combustion chambers in communication with each other, and incinerators are incinerated by the heat of combustion higher than the primary combustion chamber in the secondary combustion chamber. Preferably, the secondary combustion chamber is formed in a smaller size, i.e., a smaller volume than the primary combustion chamber, and a burner is provided between the primary combustion chamber and the secondary combustion chamber, and each side of the burner is configured to generate combustion heat in each combustion chamber. The nozzle is provided with an ignition means at the end of the nozzle, and the nozzle on the secondary combustion chamber side is provided as a larger capacity to supply a larger amount of gas and oxygen than the nozzle on the primary combustion chamber side and also in a larger number. In the incineration of the incineration, the first small combustion chamber is heated by the burner, thereby preheating the primary combustion chamber connected with the secondary combustion chamber through heat convection.

In addition, for complete combustion, it is preferable that an oxygen supply device is connected to each combustion chamber so that a high concentration of oxygen generated in the oxygen supply device is provided to each combustion chamber during combustion.

Incinerators having such a configuration can be used by being fixed to a certain ground as well as mounted on a moving means such as a vehicle.

Hereinafter, although an incinerator according to a preferred embodiment of the present invention will be described in detail with reference to the drawings, the present invention is not limited or limited by the following examples.

1 is a perspective view showing a state in which an incinerator is mounted on a vehicle according to the present invention, Figure 2 is a cross-sectional view showing the internal structure of the incinerator according to the present invention, Figure 3 is an internal structure of the oxygen generating device which is the main part of the present invention It is sectional drawing shown.

1 and 2, the incinerator according to the present invention includes the primary and secondary combustion chambers 50 and 30 in communication with each other. Accordingly, the incineration is first burned in the primary combustion chamber 50 and then reburned in the secondary combustion chamber 30 at a temperature higher than that of the primary combustion chamber 50. Therefore, one side of the primary combustion chamber 50 is rotatably provided with an opening and closing port 70 for injecting the incineration into the primary combustion chamber 50. Further, the primary combustion chamber 50 and the secondary combustion chamber 30 Burners 40 are provided to provide combustion heat to the combustion chambers 50 and 30 as nozzles 40a and 40b having different capacities on one side thereof. The first combustion chamber (2) is provided on both sides of the burner 40. 50 and the second combustion chamber 30 are provided with respective nozzles 40a and 40b adapted to generate combustion heat. At the ends of the nozzles 40a and 40b, conventional ignition means is provided and secondary combustion chambers are provided. It is preferable that the nozzle 40a on the 30 side is provided as a large capacity to supply a larger amount of gas and oxygen than the nozzle 40b on the primary combustion chamber 50 side and is provided in a larger number.

1 and 2, the size of the secondary combustion chamber 30, that is, the volume, is smaller than that of the primary combustion chamber 50. The reason for this is that when the incineration operation starts, the secondary combustion chamber 30 is heated before the primary combustion chamber 50 through the nozzle 40a of the burner 40, and the combustion heat of the secondary combustion chamber 30 is reduced to 1. This is because it is formed to be higher than the heat of combustion of the primary combustion chamber 50. More specifically, combustion is performed at 1,400 to 1,600 ° C in the secondary combustion chamber 30, and in the primary combustion chamber 50 than the secondary combustion chamber 30. Combustion takes place at low 1,200 to 1,400 ° C. Therefore, rather than starting combustion in a relatively large primary combustion chamber 50 first and then raising the temperature of the secondary combustion chamber 30, the combustion space volume, that is, the temperature of the secondary combustion chamber 30 with a small combustion volume, is increased. First, after raising the heat energy of the secondary combustion chamber 30 to the primary combustion chamber 50 through the tropical flow to some extent, using the burner 40 to increase the temperature of the primary combustion chamber 50 This is because it is superior in terms of energy efficiency and combustion efficiency. On this basis, the secondary combustion chamber 30 has a smaller size than the primary combustion chamber 50. Furthermore, since the incineration is incinerated in a large amount in the primary combustion chamber 50, the size is greatly reduced, even if the size of the secondary combustion chamber 30 is relatively smaller than that of the primary combustion chamber 50, there is no problem in the incineration operation. In addition, as described above, the secondary combustion chamber 30 has a higher heat of combustion than the primary combustion chamber 50, which is the first volume of the secondary combustion chamber 30. Thermal efficiency, that is, the combustion temperature is high due to the smaller volume, and secondly, the nozzle 40a on the secondary combustion chamber 30 side has a larger capacity than the nozzle 40b on the primary combustion chamber 50 side. In addition, the gas and oxygen supplied from the burner 40 and the oxygen generator 60, which are provided by a large number and are controlled by the controller 90, which will be described later, are firstly combusted by the nozzle 40a. Is supplied in a large amount to the secondary combustion chamber (30), and fourthly incineration The secondary combustion chamber 30 heated before the primary combustion chamber 50 to preheat the primary combustion chamber 50 heats the combustion by-product combusted in the primary combustion chamber 50 again than the primary combustion chamber 50. The heating operation is performed for a longer time, and its operation and set temperature are controlled by the controller 90 so that the heat of combustion of the secondary combustion chamber 30 is formed higher than that of the primary combustion chamber 50.

Here, a significant amount of the thermal energy provided from the burner 40 to each of the combustion chambers 50 and 30 cannot be used for the incineration operation, so that the fuel consumption of the burner 40 is increased. The present invention proposes a method of reducing fuel consumption using such waste heat.

To this end, referring to FIG. 2, thermoelectric elements 51 and 31 are installed on inner walls of the primary and secondary combustion chambers 50 and 30 to convert waste heat into electrical energy. The thermoelectric elements 51 and 31 consist of a thermocouple which generates a voltage by a temperature difference, and a thermoelectric generator which extracts the voltage generated by the thermocouple as electrical energy. Since the thermoelectric elements 51 and 31 directly convert thermal energy into electrical energy, the thermoelectric elements 51 and 31 have been attracting much attention in the field of using waste heat, and various forms have been applied for.

Heat generating elements 52 and 32 that receive electric energy from the thermoelectric elements 51 and 31 and generate heat are installed on the inner walls of the thermoelectric elements 51 and 31. The heat generating elements 52 and 32 are materials having a property of generating heat when electricity is supplied, and are heat radiating members used in various fields, that is, a type of heat sink.

Since waste heat is not lost by the thermoelectric elements 51 and 31 and the heat generating elements 52 and 32 to the respective combustion chambers 50 and 30, the corresponding thermal energy does not have to be provided from the burner 40. Therefore, the fuel consumption rate of the burner 40 is drastically lowered.

Subsequently, a dust collecting filter 20 that collects, filters, and cools high-temperature combustion products burnt in the secondary combustion chamber 30 is connected to the secondary combustion chamber 30. Inside the dust collecting filter 20, an ordinary dust collecting machine is installed. In addition, in order to efficiently cool the high temperature combustion product delivered from the secondary combustion chamber 30 closer to room temperature, the inside of the dust collecting filter 20 is preferably in the form of a venturi tube. When the high-temperature exhaust stream collected / filtered after flowing from the secondary combustion chamber 30 passes through the inside of the venturi tube-type dust collector 20, the thermal energy of the exhaust stream is converted into kinetic energy due to the pressure drop, Is lowered more easily.

The dust collecting filter 20 and the burner 40 are supplied with power from the generator 10. Each of the above components is controlled by the controller 90 provided at the top of the generator 10.

On the other hand, the combustion efficiency of each combustion chamber 50, 30 depends largely on the concentration of oxygen. Therefore, an oxygen generator 60 for supplying a high concentration of oxygen to each of the combustion chambers 50 and 30 is disposed between each of the combustion chambers 50 and 30 and is controlled by the controller 90 to supply high concentrations of oxygen to each combustion chamber. To (50,30).

As shown in FIG. 3, the oxygen generator 60 includes two compressors 110 and 130 therein, and an adsorber 120 connected between the compressors 110 and 130. Oxygen generator 60 having such a configuration is strongly sucked into the adsorber 120 after the air sucked into the air inlet 140 is compressed by the right compressor 110, the air passing through the adsorber 120 is oxygen Except the components are adsorbed to increase the oxygen concentration, this high concentration of oxygen is discharged back to the oxygen outlet 150 by the left compressor (130). High concentrations of oxygen discharged through the oxygen outlet 150 are supplied to the primary and secondary combustion chambers 50 and 30.

The adsorber 120 is made of zeolite and absorbs nitrogen, carbon dioxide, and the like except for oxygen in the air. Therefore, although the normal air is sucked into the oxygen supply device 60, since most nitrogen and carbon dioxide are adsorbed while passing through the adsorber 120, the gas discharged to the oxygen outlet 150 has a relatively high oxygen concentration. It becomes an elevated gas.

On the other hand, the various components described above are mounted on the vehicle 80, it is possible to perform incineration regardless of the incineration site. However, the incinerator according to the present invention is not limited to being mounted on a vehicle and implemented in a mobile manner, and of course, it may be fixedly installed and used at a predetermined place.

Hereinafter, the incineration operation of the incinerator having the above configuration will be described in detail.

First, incineration is introduced into the primary combustion chamber 50 through the opening and closing port 70 of the primary combustion chamber 50. After closing the opening / closing opening 70 of the primary combustion chamber 50, the secondary combustion chamber 30 having a smaller combustion volume, that is, the combustion volume, is heated first than the primary combustion chamber 50. Then, the thermal energy of the secondary combustion chamber 30 is provided to the primary combustion chamber 50 by tropical flow.

After some degree of heat transfer from the secondary combustion chamber 30 to the primary combustion chamber 50, the primary combustion chamber 50 is heated to raise the temperature of the primary combustion chamber 50 to 1,200 to 1,400 ° C. to burn the incineration. Burn. In this case, since the primary combustion chamber 50 is maintained at the above-mentioned temperature, almost all kinds of incinerations are incinerated.

Combustion by-products of various incinerations, that is, some combustion in the primary combustion chamber 50, that is, particulate soot materials are then introduced into the secondary combustion chamber 30 and reburned at a higher temperature in the secondary combustion chamber 30. At this time, the secondary combustion chamber 30 is maintained at a temperature of 1,400 to 1,650 ℃, so that the high-temperature combustion by-product delivered from the primary combustion chamber 50 is burned closer to complete combustion.

After this initial combustion operation in the primary and secondary combustion chambers 50 and 30, a large amount of thermal energy provided from the burner 40 is not available for the combustion operation. Since the waste heat is converted into electrical energy by the thermoelectric elements 51 and 31 and supplied to the heating elements 52 and 32, thermal energy using waste heat from the heat generating elements 52 and 32 is returned to the respective combustion chambers 50 and 30. Will be provided. Therefore, since the thermal energy provided by the burner 40 can be omitted by the thermal energy provided by the heating elements 52 and 32, the fuel consumption of the burner 40 is greatly reduced.

In addition, the primary combustion chamber 50 that primarily burns the combustion chamber and the secondary combustion chamber that has a smaller combustion space volume, that is, a smaller combustion volume, and are supplied at a higher temperature by supplying a large amount of gas and oxygen than the primary combustion chamber 50. By partitioning 30, garbage incineration can be achieved more efficiently.

On the other hand, during the combustion operation in the primary and secondary combustion chambers 50 and 30, a high concentration of oxygen is supplied from the oxygen supply device 60 to each combustion chamber 50 and 30. Therefore, the combustion operation close to complete combustion in each of the combustion chambers 50 and 30 becomes possible, whereby the emission of toxic substances due to combustion can be greatly suppressed.

The combustion byproduct burned twice is collected in the dust collecting filter 20 and then filtered. The high-temperature exhaust gas collected / filtered is converted into kinetic energy due to a pressure drop while passing through the inside of the venturi tube-shaped dust collector 20, and is discharged to the outside in a cooled state.

On the other hand, the controller 90 automatically adjusts the combustion time and the combustion temperature, and the amount of gas and oxygen supplied.

As described above, the incinerator according to the present invention is provided with a thermoelectric element and a heat generating element in the primary and secondary combustion chambers, so that the waste heat of the incineration can be reused again, thereby greatly increasing energy efficiency. There is an advantage.

In addition, by supplying a high concentration of oxygen to each combustion chamber through the oxygen generator, it is possible to burn more close to combustion, and as a result, it is possible to implement an environmentally friendly incinerator that can suppress the generation of toxic gases to the maximum.

In addition, two compartments of the primary combustion chamber are maintained at about 1,400 ° C., and the secondary combustion chamber is maintained at about 1,650 ° C., whereby almost all materials of the incineration are incinerated, thereby reducing the post-treatment cost after incineration as much as possible.

In particular, the incinerator according to the present invention, as implemented in the embodiment, can be mounted on the vehicle, can reduce the moving / loading costs for the incineration of waste, the problem of incineration waste in only one region, that is, It provides clues to resolve environmental problems and local residents' campaigns against incineration.

Although the present invention has been described in detail with respect to the preferred embodiment of the present invention, the present invention is not limited to the above embodiments and the present invention without departing from the gist of the present invention claimed in the following utility model registration claims Anyone with ordinary knowledge in the field will be able to implement various changes.
