The invention's effect

The present invention has the following advantages.
(1) Since it burns in a fired state except when it is ignited, the energy cost is low.
(2) Residual ash discharged from the bottom of the wood-fired potter is reduced to 1/200 to 1/300 of the combustibles charged, so the land to be landfilled is greatly reduced.
(3) Due to the smoldering method, almost no NOX, SOX, dioxin, CO2 etc. are generated, but most of them are returned to the smoldering machine and circulated, so the amount of exhaust gas is very small. Some exhaust gases are also harmless with smoke, deodorant, and purification. Therefore, environmental problems such as exhaust gas pollution and global warming do not occur.
(4) Residual ash discharged from the bottom of the pottery oven is ceramicized and can be used as a recycled product.
(5) Pyroligneous acid liquid, tar, etc. recovered from the roasting gas can be used as recycled products or as an auxiliary combustion material for roasting.
(6) Because the furnace is small and smoldering, it does not require large-scale equipment and does not require special qualifications or technology for operation.
(7) Since no oil burner or gas burner is used, no dust is generated silently and the neighborhood is not disturbed.
(8) The outer wall temperature of the pottery ware only rises to about 50 ° C and is low temperature, so there is no risk of fire.

Yes. Reference numerals 26a to 26c denote air supply valves. Permanent magnets 25a to 25c are fixedly provided on the wall surfaces of the sinter burner 1 in the vicinity of the supply pipes 23a to 23c.

Next, the operation of this embodiment will be described. An organic waste material obtained by removing non-combustible materials such as metal, glass, ceramics, etc. from garbage generated in various facilities such as agriculture, fishery, industry, commerce, home, etc., is introduced from the inlet 7 of the smelter 1. Next, electricity is supplied from the power supply cords 9a and 9b to the electric rod 10 to heat the electric heating rod 10, and the organic waste material is ignited. At the stage of ignition, the lid 8 is closed to limit the amount of oxygen, and the supply of oxygen is adjusted by the air supply valves 26a to 26c. If it does so, organic substance waste will be in a calcination state, and will maintain that state, even if it does not heat from the outside with the electric rod 10 grade | etc.,.

FIG. 4 schematically shows this state. From the top organic waste region (80-100 ° C), dry region (180-200 ° C), carbonized region (450-500 ° C) ashing region (700-900 ° C) high temperature region (900-1000 ° C), ceramic ash region Each region is formed in a layered form (800 to 900 ° C.) and smoldering proceeds. At this time, good results can be obtained by holding the electromagnetic rod 10 at 800 to 900 ° C. In addition, the gas that is magnetized by the action of the permanent magnets 25a to 25c fixed to the air supply pipes 23a to 23c generates plasma with high heat (800 to 900 ° C.) in the furnace, and a small amount of oxygen is supplied thereto. Then, highly reactive electronic oxygen (negative ions) is formed, and toxic substances contained in the organic waste are oxidatively decomposed. Charcoal produced in the wood-fired oven 1 is used as a soil conditioner, filter material, deodorant material, humidity control material, etc., and ceramic ash is used as a glaze. Such useful residues are taken out from the residue discharge port 11 and the ceramic ash removal port 18.

Next, the smoldering gas generated by pyrolysis in a high temperature range of 900 to 1000 ° C. flows upward and flows into the dry distillation liquid recovery chamber 2 while drying the upper combustible material. Therefore, it cools and condenses while passing through the processing compartments 2a and 2b, and a dry distillation liquid such as a wood vinegar is generated. The dry distillation liquid is taken out from the dry distillation liquid outlet 5 and used as a valuable material such as a soil conditioner, a preservative, and an insect repellent. On the other hand, the remaining smoldering gas is sent to the solution tank 15 of the smoldering gas processing section B through the smoldering gas feed pipe 3.

The solution tank 15 contains dry distillation liquid such as wood vinegar or deodorant liquid, neutralizing liquid, and the like. In the solution tank 15, the smoldering gas is discharged below the surface of the compartment 15a, and rises as bubbles while eluting components such as tar and carbon by the solution. The air bubbles that have risen are sucked into the turbine 17 from the upper suction pipe 17a. In the turbine 17, the gas-liquid constituting the bubbles is agitated by high-speed rotation and becomes fine bubbles, and sufficient contact between the gas and liquid is performed, so that the gas-containing components are further eluted into the liquid side and enter the compartment 15 b. The fine bubbles that have entered the compartment 15b enter the compartment 15c through the filter 20, but by passing through the filter 20, the bubbles are broken and the gas and liquid are separated. The compartment can be divided into four or more, but the basic technical idea is the same. When the water content of the organic waste material to be added is low, the solution surface in the solution tank is lowered, so that the solution is replenished. When the water content is high, the solution surface is raised and the solution needs to be extracted. The extracted solution can be reused for replenishment, or tar, carbon, etc., obtained by evaporating moisture with smoldering heat can be used as a combustion aid for a sinter burner.

The gas thus separated (smoked gas) is a odorless, smokeless, harmless, deodorized, neutralized, odorless, smokeless, or harmless component. A part of the smoldering gas treated in this way is discharged from the exhaust pipe 24 to the atmosphere, but since it has been cleaned as described above, no environmental problems occur. The other smoldering gas passes through the smoldering gas return pipe 4, passes through the fan 21, the air supply header 22, and the air supply pipes 23 a to 23 c, and circulates back to the calcination machine 1. At this time, outside air is also sucked by the fan 21 and is sent to the smoldering machine 1 together with the smoldering gas.
