Apparatus for treating organic wastes

Abstract

The invention provides a device of processing organic waste capable of removing offensive odor by simple apparatus and charring the hydrous organic waste at low energy. The device of processing organic waste (1) comprises a drying oven (10) for drying the organic waste by contacting the organic waste with the gas; a retort (20) for charring the dried organic waste; and a waste processing portion (30) for innoxiously processing the gas discharged from the drying oven (10); the device of processing organic waste is characterized that: the waste processing portion (30) comprises a processing tower having divided separation chamber, a processing liquid storage tank for storing the processing liquid, and a waste spraying mechanism; the waste spraying mechanism mixes the processing liquid with the gas to form mixture; and the mixture gas flows into the processing tower to innoxiously process the gas.

Description

technical field [0001] The invention relates to a treatment device for organic waste. Background technique [0002] Recently, from the standpoint of environmental protection, etc., water-containing organic wastes such as food residues and livestock excrement are expected to be efficiently utilized as fuel by carbonization treatment. [0003] Furthermore, many carbonization treatment methods of organic wastes have been disclosed and put into practical use. [0004] As a carbonization treatment method of such organic waste, for example, a method is disclosed in Patent Document 1: image 3 Like the carbonization treatment device 100 shown in (a), after the water content of the organic waste is reduced by heating with high-temperature gas in the drying furnace 110, the organic waste is carbonized in a high-temperature atmosphere in the carbonization furnace 120. In addition, the boil-off gas generated in the drying furnace 110 is transported to the combustion furnace 130 throug...

AI Technical Summary

Problems solved by technology

[0008] However, in the above-mentioned existing carbonization treatment devices 100 and 200 for organic waste, although the thermal energy of the carbonization furnace 120 and 220 is used in the drying furnace 110 and 210 to perform drying treatment on the organic waste, the carbonization treatment can be achieved. However, in order to maintain the drying furnace 110, 210 in a high-temperature atmosphere so that the drying process can be efficiently performed, heating is required; the combustion treatment of the boil-off gas G generated in the drying furnace 110, 210 needs to be carried out at a high temperature Etc., for this reason, in drying furnace 110,210 and charring furnace 120,220 and burning furnace 130,230 need to have heating unit respectively, thus energy consumption saving degree is limited

[0009] In addition, since the combustion treatment of the boil-off gas G takes a certain amount of time, depending on the processing capabilities of the drying furnaces 110 and 210 and the carbonization furnaces 120 and 220, large-scale combustion furnaces 130 and 230 are sometimes required, so the carbonization treatment devices 100 and 200 Overall compactness is limited

[0010] In addition, when using the drying furnaces 110 and 210 to dry organic waste, a large amount of high-temperature gas is required, but since the combustion treatment by the combustion furnaces 130 and 230 takes a certain amount of time, a large amount of high-temperature gas cannot be discharged continuously, and the organic waste takes a long time to dry
