[Prior art]

 Traditionally, the main fuel, charcoal, has generally been produced in a charcoal carbonization furnace. This charcoal carbonization furnace used a clay kiln filled with soil and a stone kiln in which stones and clay were stacked, and wood was burned and carbonized in this kiln. In addition, in recent years, there has been a carbonization treatment technique in which charcoal is burned in a carbonization furnace or a drum that uses some refractory bricks. When wood, which is a carbon material, is put into a kiln and carbonized, a raised tree that is ashed during carbonization to accelerate ignition of the carbon material is placed on the upper part, and a lower part of the carbon material that evaporates during carbonization is placed. It was necessary to have a floor covering that absorbs the water content and keeps the heat inside the kiln. Furthermore, the charcoal carbonization process involves opening and closing the flue vents and vents to prevent the ignition of raised trees from extinguishing due to the color and odor of smoke emitted from the chimney, and additional measures to increase the amount of coal collected. The timing of firing and the timing of kiln stopping to obtain high-quality charcoal are important operations, and this charcoal-burning operation used the wealth of experience to produce charcoal.

In the figure, 1 is a carbonaceous material for producing charcoal, 2 is an industrial waste for performing a carbonization treatment using the carbonization furnace of the present invention, and 3 is a crushed carbonaceous material 1 or industrial waste 2 into a predetermined size. Crusher, 4 is a carbonization furnace, 5 is activated carbon produced as carbonaceous carbide in the carbonization furnace 4, and 6 is an organic fertilizer produced as carbonaceous carbide as described above.

Reference numeral 7 denotes smoke emitted from the carbonization process of the carbonization furnace 4 and discharged. The smoke 7 is completely combusted by a combustion type smoke eliminating device 8. Reference numeral 9 indicates the waste heat generated and discharged in the combustion type smoke eliminator 8. In the drying furnace 11 to which the waste heat 9 is supplied, the waste heat 9 is used to generate a high water content waste 10 having a high water content. Let it dry. Then, the waste 10 dried in the drying furnace 11 is crushed by the crusher 12 and sorted by the sorter 13 to be a raw material for the organic fertilizer, feed or medicine 14. Reference numeral 15 is an exhaust gas generated and discharged in the drying furnace 11. The exhaust gas 15 is a malodorous gas having an odor and is supplied to the deodorizing device 16 and completely combusted to be odorless and harmless. Reference numeral 17 denotes waste heat generated in the deodorizer 16 and discharged. The waste heat 17 is guided to the steam generator 18, and the activation device 19 uses the water vapor generated in the steam generator 18 to activate the powdered activated carbon 20. The activation process is performed. Reference numeral 21 is a hot water generator that obtains hot water from the waste heat 17, and the hot water of the hot water generator 21 is supplied to the hot water supply equipment 22 and the heating equipment 23.

In the carbonization treatment of the recycling plant system of the present invention configured as described above, the carbonaceous material 1 which is a raw material of wood, bamboo and the like and the industrial waste 2 such as wood waste, old tires, dehydrated sludge and the like have a predetermined size. Furthermore, it is crushed by the crusher 3 and carbonized in the carbonization furnace 4. The carbonization furnace 4 of the present invention is configured as follows. That is, the actual volume of the basket containing the carbonaceous material is set to 5 m ^3, and all the materials are made of stainless steel. The carbonization furnace 4 in which this carbon cage is put is made of iron, and the inner surface of the furnace is castable and refractory to improve heat retention and heat insulation. Next, in order to speed up the ignition of the raw materials, an automatic ignition burner was used to create a structure in which the flow was even from the upper surface of the furnace. As a result, the time from ignition to ignition is shortened to 1/3 to 1/4 as compared with the conventional case.

Furthermore, the temperature inside the furnace is automatically controlled, and the height of the chimney is made twice as high as the height of the carbon cage, so that the self-combustion efficiency after ignition is increased and the production yield of carbide is reduced. Improved. In this carbonization furnace, good quality carbide can be processed in a process of 12 hours.

The carbon-based carbide thus carbonized is used as activated carbon 5, organic fertilizer 6 or a soil conditioner. Further, the flue gas 7 produced in the carbonization process in the carbonization furnace 4 is supplied to the combustion type smoke eliminator 8 and becomes smokeless. As for the smoke elimination method, a smoke conduit is connected to the bottom of a combustion-type cylindrical combustion furnace, and smoke is introduced from the bottom surface of the combustion furnace. About 0.5 liter of fuel (kerosene, heavy oil, waste oil) is injected into the bottom side of the furnace, and air is blown into the furnace by a blower from the perforated pipe installed in the center of the furnace. The fuel is vaporized by the action, and when ignited, it becomes a state of complete combustion. At that time, the temperature inside the furnace is around 1500 ° C, and the temperature is adjusted by the air volume of the blower and the injection amount of fuel, and its function is controlled by electrical control.

It takes 3 to 5 minutes for the temperature in the furnace to reach around 1500 ° C., and when a complete combustion state is reached, smoke is introduced and mixed with the vaporized fuel to complete combustion. Therefore, no smoke is emitted at the exhaust port of the combustion furnace and the gas is discharged as a transparent gas. The temperature at the exhaust port is around 1000 ° C.

The waste heat 9 of about 1000 ° C. discharged from the combustion type smoke eliminator 8 is used as a heat source of the drying furnace 11 to which the high water content waste 10 is supplied. A heat resistant conveyor (not shown) is installed inside the drying furnace 11, and a high moisture content waste 10 having a large amount of water is placed on the heat resistant conveyor and dried using the waste heat 9. . The dried high-moisture content waste 10 is pulverized by a pulverizer 12 into powder, and is sorted by a sorter 13 to be used as a raw material for organic fertilizers, feeds or pharmaceuticals 14.

On the other hand, the exhaust gas 15 generated in the drying furnace 11 is supplied to the deodorizing device 16. Since the exhaust gas 15 of the drying furnace 11 is a malodorous gas having an odor, this malodorous gas is completely burned by the deodorizing device 16 like the combustion type smoke eliminating device 8 to be deodorized or deodorized to be harmless and odorless. Further, since the waste heat 17 discharged in the deodorizer 16 is high in temperature, it is supplied to the steam generator 18 and the hot water generator 21, and the steam generator 18 generates steam, which is used to generate powdered activated carbon. 20 is used for the activation device 19 required for generation.
