Problems solved by technology

[0013] However, in this carbide production method, since only the heat energy in the exhaust steam is recovered, the recovered heat is not very large.
In addition, there is a possibility that impurities and odor contained in the exhaust steam are discharged from the thermal decomposition device

Embodiment 1

[0077] figure 1 It is the whole structure diagram of the carbonization apparatus for activated carbon manufacture of this invention. As shown in the figure, in the carbonization device 10 for activated carbon production, there is provided: a processing object supply mechanism 20, which stores organic processing objects such as garbage, wood, meat and bone meal, rags, plastics, etc. The object is supplied into the drying furnace 30; the drying furnace 30 introduces the water vapor discharged from the carbonization furnace 40 to dry the object to be processed, and discharges the processed object and the used water vapor; the carbonization furnace 40 is supplied by The object to be processed dried by the drying furnace 30 is introduced into superheated steam from the high-temperature steam generating device 60 to carbonize the object to be processed, and the carbonized activated carbon and the used water vapor are discharged; The carbonized activated carbon is cooled and stored....

Embodiment 2

[0094] In the above-mentioned examples, the activated carbon was used for carbonization treatment such as drying, carbonization, and activation of organic objects to be treated using two types of reaction furnaces: the drying furnace 30 (first reaction furnace) and the carbonization furnace 40 (second reaction furnace). The carbonization apparatus for production has been described, but the present invention is not limited to the example of carbonization treatment using two types of reaction furnaces.

[0095] For example, depending on the type of object to be treated and the amount of treatment, if high-temperature superheated steam is generated by using superheated steam that has been heat-recovered from the high-temperature exhaust gas discharged from the deodorization furnace 70, and the high-temperature superheated steam The object of the present invention can also be achieved by introducing into a dry carbonization furnace (first reaction furnace) to dry and carbonize the ...

Abstract

A carbonization apparatus (10) for producing an activated carbon wherein an organic based material to be treated is carbonized, which comprises a carbonization furnace (40) wherein overheated steam is introduced to carbonize a material to be treated and the spent steam is discharged, a drying furnace (30) wherein the steam discharged from the carbonization furnace (40) is introduced to dry the material to be treated and the spent steam is discharged, a high temperature steam generating device (60) wherein steam is introduced and the high temperature overheated steam for use in supplying to the carbonization furnace (40) is formed, a deodorizing furnace (70) wherein impurities contained in the spent steam discharged from the drying furnace (30) are heated to deodorize them through burning and discharging a high temperature an exhaust gas is discharged, and a waste heat boiler (80) wherein water is heated by using the high temperature exhaust gas discharged from the deodorizing furnace (70) and the steam for supplying to the high temperature steam generating device (60) is formed. The carbonization apparatus allows the production of an activated carbon having high quality at a low cost, by recovering and reutilizing the heat contained in the exhaust gas which has been discharged from a deodorizing furnace and has been subjected to a burning treatment.

Description

technical field [0001] The present invention relates to a carbonization device for activated carbon production that performs carbonization treatments such as drying, dry distillation, activation, etc. of organic objects to be processed such as garbage containing water, wood, meat and bone meal, rags, and plastics. Background technique [0002] Conventionally, it is known that wastes containing moisture, waste wood, and disposable diapers are mainly exposed to high-temperature steam at 510 to 900°C in an oxygen-free state to carbonize them. Waste disposal methods. In this waste treatment method, by exposing waste to high-temperature steam for a predetermined time, the volume or weight can be reduced to about 1% of that before treatment, and carbonization can be effectively performed (for example, refer to Patent Document 1). [0003] In addition, conventionally, when organic wastes such as brewer's grains are dried to obtain carbides and the like, heat treatment devices for ...
