Abstract:
1. A concentrated acid treatment unit in which a phenol sorped raw material obtained by subjecting phenol to sorption by a botanical resource is reacted with concentrated acid and then phenol is added to the resultant treated liquid to extract a lignophenol derivative, comprising: a reaction section for obtaining treated liquid by the reaction between the phenol sorped raw material and the concentrated acid; and an agitation extraction section for adding phenol to the treated liquid to thereby extract mixed solution including a lignophenol derivative, wherein the reaction section has a reactor body and agitation blades provided in the reactor body such that the highly viscous and massive treated liquid obtained by the reaction between the phenol sorped raw material and the concentrated acid is rolled by an inner circumference face of the reactor body and the agitation blades for fragmentation, wherein the agitation extraction section includes: a cylindrical extraction container for which a shaft axis direction is an up-and-down direction; a rotation axis provided in the cylindrical extraction container; a plurality of circular plate-like flashboards that are arranged in a shaft axis direction of the rotation axis, the plurality of circular plate-like flashboards are configured so that an outer diameter is close to an inner face of the cylindrical container and have a small opening for communicating treated liquid; extraction agitation blades provided among the flashboards to agitate treated liquid, a plurality of inlets that are provided at one side of the cylindrical extraction container and that are arranged in a longitudinal direction to correspond to the respective flashboards; and a plurality of liquid outlets that are provided at the other side of the cylindrical extraction container and that are arranged in a longitudinal direction to correspond to the respective flashboards, whereas treated liquid sent from the reaction section is introduced through an inlet appropriately selected from among the inlets into the cylindrical extraction container, phenol is introduced through a liquid outlet appropriately selected from among the liquid outlets into the cylindrical extraction container, and mixed solution of the treated liquid and phenol is sent through another liquid outlet appropriately selected from among the liquid outlets.
