The air tank 3 is to cool carbonated gas transferred through a series of the catalysts, the first through fifth catalysts, into temperature approximate to room temperature. Such an air tank 3 has an airtight receptacle structure in which a plurality of gas convection preventing plates 31 are provided with a constant capacity. On one side of the air tank 3, an inflow opening 32 is formed through a pipe connection. On one side of the inflow opening 32, a discharge opening 33 is formed through a pipe connection.

The vacuum pump 6 is a kind of carbonated gas exhausting units for pressurizing the carbonated gas transferred through the auxiliary filtering device 4 by a constant pressure and for transferring it to the water tank 7. One side face of the vacuum pump 6 is preferably connected to an air generation pipe 61 having numerous air generation holes P as shown in Fig. 1.

The water tank 7 finally filters the carbonated gas flowing in through the vacuum pump 6, and exhausts it in air. Such a water tank 7 is formed by filling up a receptacle inside of a constant quantity with water. One side upper part of the water tank is provided with a gas exhaust opening 71.

While, the electron control panel device 8 automatically controls a series of constructive parts described above, so as to control a series of driving relations required for a carbonizing operation, such as temperature and time of a far infrared rays heater, temperature of respective catalysts, and other driving relations, etc. Preferably, the electron control panel device 8 as the automatic control unit is formed as a general electron control device having a circuit connection relation as shown in Fig. 2.

Therefore, with such a described construction, and in a mutual combination with the carbonizing apparatus using the far infrared rays heater, as shown in Fig. 1, the far infrared rays heater 11 and the carbonizing receptacle 12 are installed inside the body case 1, and the body case 1 is formed in one body with the catalyst insulation 2 in structure connected through an upper center portion of the body case 1. That is, as shown in Fig. 1, the air tank 3, the auxiliary filtering device 4 and the vacuum pump 6 are connected with one another in a serially piped connection structure. Under such a connection construction, the ozone generator 5 as a separate construction is installed on one side of the vacuum pump 6. The ozone generator 5 is coupled with the vacuum pump 6. Further, the air generation pipe 61 of the vacuum pump 6 is structured to be inserted into the water tank 7. Such a serial construction embodies the inventive carbonizing apparatus using the far infrared rays heater.

Operations of the carbonizing apparatus using the far infrared rays heater will be described as follows.

First, the carbonizing receptacle 12 installed inside the case body 1 is filled with waste matter 10. Under such a state, when initial power is supplied by using the electron control panel device 8 shown in Fig. 2, the far infrared rays heater 11 installed inside the case body 1 emits radiant heat of high temperature, and heats the carbonizing receptacle 12 to start to progress the carbonizing operation.

Such a far infrared rays heater 11 has a line connection structure closely arrayed on the bottom face of the carbonizing receptacle 12, and the line closely, arrayed on the bottom face of the carbonizing receptacle 12 is inserted and installed into the inside of the carbonizing receptacle 12 through an upper part face of the carbonizing receptacle 12. According to such a structure, direct heat of a range of 350~400°C is applied onto the waste matter filled into the carbonizing receptacle 12. At this time, the carbonizing receptacle 12 with ceramic urethane coating process operates so that carbonated material may not get scorched thereto.

The insulation brick 13 as an inner wall face of the case body 1 is made of oxide aluminum, alumina and ocher, and has an insulation effect enduring against a temperature range of 1200~1300°C. The insulation brick 13 also has a function of partially suctioning vapor generated in the carbonizing operation, and simultaneously evaporates and removes the suctioned vapor by using carbonizing heat.

On the other hand, in case that waste matter is carbonized through the far infrared rays heater 11 and the carbonizing receptacle 12, noxious carbonated gas is generated inside the body case 1, and such a generated carbonated gas is passed through a primary dehumidifying procedure of the dehumidifier 21, and then flows into the catalyst insulation 2.

Subsequently, the catalyst insulation 2 turns power on at 350°C of the carbonated gas that flows thereinto through a temperature sense of the catalyst automatic temperature sensor 28, and heats the catalyst heater 22 and the catalyst alien substance removal heater 29. Interior temperature of a series of catalysts, the first through fifth catalysts, as an accumulated structure, is maintained in a temperature range of 250 ~350°C by such a heating operation, and primarily filters the pollution material of the carbonated gas through the catalysts 23, 24, 25, 26, 27. At this time, the catalyst alien substance removal heater 29 has a self cleaning function, and operates for about 2 hours in a temperature range of 500 ~550°C, one time every a constant period based on a carbonizing operation, about three months, so as to selectively remove alien substances remained inside the first through fifth catalysts. While such a catalyst alien substances removal heater 29 operates, it is desirable not to progress a specific carbonizing operation.

Next, the carbonated gas passed through the catalyst insulation 2 inflows into the air tank 3 along a piped line. According that the carbonated gas flows into the air tank 3, the gas convection preventing plate 31 disposed inside the air tank 3 delays a staying time of the fiown-in carbonated gas so as to cool temperature of the carbonated gas into temperature approximate to room temperature.

The carbonated gas passed through the air tank 3 flows into the auxiliary filtering device 4 through a piped line. In the auxiliary filtering device 4, trimethylamine, monomethylamine and ammonia etc. are removed from the carbonated gas through the basic activated carbon 41. Benzene, toluene, xylan, styrene, carbon bisulfide, acetic acid, bodice acetic acid, lactic acid, hydrogen sulfide, methylmercaptan, and dimethylsulfide, etc., which are contained into the carbonated gas, are eliminated through the acid activated carbon 42. Ethanol, acetic acid, bodice acetic acid, lactic acid, formicaldehyde, acetaldehyde, ethylene, and carbon monoxide, etc., which are contained into the carbonated gas, are removed through the neutral activated carbon 43.

The carbonated gas from which the harmful material is removed through the auxiliary filtering device 4, flows into the inside of the vacuum pump 6. Under such a state that the carbonated gas is mixed with ion gotten from the ion generator 5, the gas is transferred to the inside of the water tank 7 through the air generation pipe 61. Then, the carbonated gas is finally filtered through water filled into the water tank 7, and exhausted to the air through the gas exhaust opening 71. Thereby, all of carbomzing operations are completed.

When all the carbonizing operation were completed, the cooling fan 14 and the blast suction opening 15 formed on the case body 1 are automatically driven by the electron control panel device 8, to compulsively ventilate and cool a heat source of the case body 1 inside heated through the carbonizing operation. When temperature of the carbonizing receptacle inside the case body 1 falls to

75 ~ 80°C by such a cooling operation, a buzzer rings by a temperature sense of the carbonizing temperature sensor (not shown in the drawings).

Like this, when the buzzer rings to inform a worker of a completion of the carbonizing operation, the worker opens the door D of the body case 1 as shown in Fig. 2. Under such an opening state of the door, the carbonizing receptacle 12 that fallen in temperature, is taken out of the body case inside, to the outside. The carbonizing matter 10 is finally processed as waste matter.

INDUSTRIAL APPLICABILITY As afore-mentioned, in accordance with the present invention, a carbonizing apparatus using a far infrared rays heater can extremely heighten an operation efficiency by shortening a temperature rise time necessary for a carbonizing operation through a direct heating method using a cartridge heater of far infrared rays, and thus by preventing an unnecessary loss of power. In addition, a carbonizing apparatus using a far infrared rays heater can prevent a serious air pollution, by rapid cooling a carbonizing receptacle through a heat cooling device so as to easily discharge carbonized matter, and simultaneously, by effectively removing various kinds of noxious gases and a bed smell generated in the midst of a carbonizing operation through a filtering unit having multi filtering steps.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without deviating from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope . of the appended claims and their equivalents.
