Embodiment Construction

[0026] The present invention is illustrated by the following preferred examples, but is not limited thereto.

[0027] The multi-stage organic matter drying system of the present invention has the conveying unit (each stage is indicated by reference numeral 4 ) and the drying chamber 1 for accommodating the conveying unit in a multi-stage manner by conveying the organic matter containing moisture such as sludge from the upper stage to the lower stage. The drying chamber sends out superheated steam (a-c) to dry the organic matter, and it is characterized in that there are N (N is a natural number of 2 or more) introduction of superheated steam (a-c) into the drying chamber 1 ports (21-23); N±1 export ports (31, 32) leading out the superheated steam (d, e) from the drying chamber 1 .

[0028] As the handling unit used in the multi-stage organic matter drying system of the present invention, such as figure 2 As shown, a plurality of rakes 8 are arranged on the conveyance table 4...

Abstract

An object of the present invention is to provide a multi-stage organic matter drying system, which is easy to control the overall temperature, has high heat utilization efficiency, and can suppress the flow rate of superheated steam from becoming too high even when a low-temperature heat source is used. The multi-stage organic matter drying system has a conveying unit for conveying organic matter from the upper stage to the lower stage in a multi-stage manner (4), and a drying chamber (1) for accommodating the conveying unit, and superheated steam (a-c) is sent into the drying chamber, And the drying of the organic matter is characterized in that it has: N (N is a natural number greater than 2) inlets (21-23) for introducing superheated steam into the drying chamber; N±1 outlets (31, 32).

Description

technical field [0001] The present invention relates to a multi-stage organic matter drying system, in particular to a multi-stage organic matter drying system used for drying organic matter containing a large amount of water such as sludge. Background technique [0002] In order to dry organic matter containing a lot of water such as sludge, a multi-stage organic matter drying system has been proposed that transports organic matter from the upper level to the lower level in a multi-stage manner, and sends superheated steam to dry the organic matter. [0003] As shown in Patent Document 1, organic matter is successively transported horizontally by a plurality of rotating rakes arranged at each stage, drops at the end of each stage to the next stage, and is continuously conveyed laterally by the rakes of the lower stage. In this way, the organic matter is transported in a multi-stage manner from the upper stage to the lower stage. Then, the heating gas flows in the same dire...
