The steam steamed by the high-temperature dry distillation gas is taken out of the latter half transfer means, and the high moisture content biomass is highly dried by recharging and supplying the steam into the first half of the transfer means. It is characterized by that way to.

In order to solve the above problems, the present invention provides an apparatus for producing carbide from a biomass resource containing a large amount of water, the hopper being charged with a high moisture content biomass, and the high moisture content biomass as the hopper.

  Next, a production method for carbonizing cow dung as a biomass resource containing a lot of moisture to obtain a carbide using the above production apparatus will be described in detail.

    Usually, cow dung contains about 80% of water. Such cow dung is introduced into the storage box 13 by opening the opening / closing door 11 of the hopper 1 and entering from the inlet 12. Then, since the storage box 13 is heated by entering the space 15 of the storage box 13 by the later-described dry distillation gas supplied through the cylindrical hollow space 22C, the low-temperature vaporized gas containing ammonia or the like as the cow dung temperature rises. Occurs. This low-temperature vaporized gas is recovered from the recovery unit 16 and discharged to a device (not shown).

  And it is taken in into the screw conveyor 21 from the storage box 13 through the discharge port 14 and the intake port 221 of the screw conveyor 21 which is the first-half transfer means 2. The taken-in cow dung is fed into the conveyor 21 at the rear end of the conveyor 21 by the rotation of the screw 23 rotating by the power of a motor (not shown).

The cow dung fed into the feed port 222 is transferred into the screw conveyor 31 through the intake port 321 of the screw conveyor 31 which is the second half transfer means 3.
The cow dung that has entered the screw conveyor 31 is transferred to the take-out port 322 through the cylindrical casing 32 by a screw 33 that is rotated by a motor (not shown). The cow dung that has reached the take-out port 322 is sent to the carbonization furnace 4. And cow dung is carbonized in the carbonization furnace.

  Dry distillation gas is generated during carbonization. This dry distillation gas has a low temperature of about 400 ° C. and contains toxic substances such as dioxins. The dry distillation gas generated in the carbonization furnace 4 is put in the combustion means 5 and heated to 800 ° C. or more by the combustion. Then, the toxic substances in the dry distillation gas disappear.

  The combusted dry distillation gas, which is no longer toxic at the high temperature, is supplied from the rear side (bearing 34A side) into the hollow space 333 of the hollow shaft 331 of the screw 33 of the latter half transfer means 3. The high-temperature dry distillation gas that has entered the hollow space 333 heats the hollow shaft 331 and the mountain-shaped screw blades 332 from the inside to a high temperature. Subsequently, it is supplied to a cylindrical space 22C formed by the cylindrical inner casing 22A and the cylindrical outer casing 22B of the front half transfer means 2 to heat the cylindrical inner casing 22A. Furthermore, it is sent to the space 15 of the storage box 13 and used as energy for heating the cow dung in the storage box 13, and the temperature of the dry distillation gas becomes 200 ° C. or less. And it discharge | releases in air | atmosphere from the hopper 1 side edge part.

  The screw 33 supplied to the hollow space 333 of the hollow shaft 331 is heated by the high-temperature dry distillation gas, and the cow dung between the casing 32 and the screw 33 is heated. The water in the cow dung becomes hot steam and evaporates, and the cow dung is dehydrated.

  The high temperature steam generated here is taken out of the casing 32 from a high temperature steam recovery section 323 which is a part of the steam supply means 7 provided at an appropriate position of the cylindrical casing 32 of the screw conveyor 3. Then, the high-temperature steam is supplied to the hollow space 233 of the hollow shaft 231 of the screw conveyor 21 of the front half transfer means 2 through the pipe 324 attached to the steam recovery part 323.

  Further, the high temperature dry distillation gas supplied to the cylindrical space 22C of the screw conveyor 21 heats the cylindrical inner casing 22A, and the water of the cow dung is heated by the high temperature heat, and the water is vaporized and dehydrated.

  Further, the high-temperature water vapor supplied to the hollow space of the hollow shaft 231 is supplied from the hollow shaft 231 to the through holes 231A, 231B, 231C,... Is done.

  Cow dung is heated by the high temperature heat of the heated cylindrical inner casing 22A. And the water vapor | steam which the water | moisture content of cow dung was steamed, and the steam 231A, 232B, 232C ... which heated the thin pipe 232 and the water | moisture content of the cow dung was heated and steamed are the water vapor | steams attached to the cylindrical casing 22 in the right place. It is supplied to the hollow space 233 of the hollow shaft 231 through the recovery hole 223 and the pipe 224. Then, the screw blade 232 is heated again and used for heating and dehydrating cow dung. The water vapor supplied to the hollow space 233 uses the heat for dehydration of cow dung, lowers the temperature, and becomes liquid droplets and liquefies. The liquefied moisture is discharged from the through hole 225 on the bearing 24 A side of the hollow shaft 231 and stored in the storage tank 8. Note that even when the high-temperature steam reaches the hollow space 233 via the thin pipes 231A, 232B, 232C,... Of the screw blades 232, it is discharged from the through hole 225 in the steam state even in the steam state.

  Thus, high quality carbide can be obtained by heating and dehydrating the cow dung during the transfer to the carbonization furnace 4 to reduce the water content of the cow dung to 20% or less.

  If the water content of cow dung is reduced in advance, the dry distillation gas generated in the carbonization furnace 4 will reduce the water content and water vapor, so the fuel (heat quantity) for detoxification is increased by heating to a high temperature (800 ° C) or higher. Can be reduced.
