Kind Code:
A3
Abstract:
The present invention relates to a sludge heating unit, to a sludge heating method, and to a sludge hydrolysis apparatus using same, which can perform sludge hydrolysis in an effective manner while reducing energy consumption. To this end, the present invention provides a sludge heating unit comprising a hydrolysis vessel in which an introduced sludge is subjected to hydrolysis through the contact with vapor in the space filled with the vapor, a discharge vessel having a path for discharging the sludge which has undergone the hydrolysis, a sludge space formed in the hydrolysis vessel and filled with the sludge, a partition wall for defining a vapor space for the passage of the vapor, and a stirring device which reciprocates and rotates between the sludge space and the vapor space to stir the vapor and the sludge and move the sludge in the direction of the discharge vessel at the same time. The present invention also provides a sludge heating method and a sludge hydrolysis apparatus using same.
