WO2005063923B1 - Carbonization apparatus for producing activated carbon - Google Patents

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.

This correction is given on page 9 of the specification. [0031] Step 7-8 [Lines of superheated steam from the outside of the cylindrical part 43 from the outside of the cylinder 43 in the same direction as the direction of rotation of the stirring blade 44] It is based on the water vapor inlet 46 to be introduced, and the description of '· · ·', and Figures 1 and 2.

 With regard to claim 2 item, “with the object to be processed and direct contact heat transfer” was added and corrected in two places. This correction is given on page 9 of the specification. [00 30] Paragraphs 5 to 7 [· · · · Water vapor from the outside of the cylindrical portion 33 from the outer side of the stirring blade 34 in the same direction as the direction of rotation of the stirring blade 34 (tangential direction Water vapor inlet 36 to be introduced into the), · · ·, page 13 [0050] Paragraphs 4 to 5 "· · · Water vapor mixes well with the processing object being sold and moved by the stirring blade 34 While the thermal decomposition · · · · ·, and is based on the description of Figure 1 and 2.

 With regard to claim 3 item, we corrected “by processing object and direct contact heat transfer” at three locations and corrected. This correction is made on page 9 of the specification [00 30] paragraph 5 to line 7, page 13 [0050] paragraph 4 to line 5, page 1 1 [0044] paragraph 1 to line 2, page 7 [0070] ] Based on the description in paragraphs 2 to 5 and figures 1 and 2.

 There is no change to items 4 and 12 of the claims.

 The cited documents 1 to 4 disclose nothing about drying and carbonizing the object to be treated by direct contact heat transfer between the superheated steam (or steam) and the object to be treated, and it is even suggested. not here.

Also, cited reference 5 indicates that the air containing steam is tangential to the separation tank. However, this is the purpose of separating tar etc. from air, as in the present invention, “It is heated while mixing well with the object to be treated, and the object to be treated is treated by direct contact heat transfer. Unlike the purpose of drying and carbonizing objects, the present invention is therefore not easily identifiable from the cited references 1, 2 and 5.

 From the above, the amended claims are considered to be novel and inventive in all of the cited documents.
