Abstract

A chemical reaction apparatus includes: a horizontal flow-type reactor inside of which has been partitioned into multiple chambers by multiple partition plates, and a liquid content horizontally flows with an unfilled space being provided thereabove; a microwave generator that generates microwaves; and at least one waveguide that transmits the microwaves generated by the microwave generator to the unfilled space in the reactor. The content flows over each of the partition plates, and, in each chamber, a weir height on an inlet side is higher than a weir height on an outlet side by at least an overflow depth at the partition plate on the outlet side.

Claims (21)

1. A chemical reaction apparatus, comprising:

a horizontal flow reactor inside of which has been partitioned into multiple chambers by multiple partition plates, and a liquid content horizontally flows with an unfilled space being provided thereabove;

a microwave generator that generates microwaves;

at least one waveguide that transmits the microwaves generated by the microwave generator to the unfilled space in the reactor; and

at least one agitation unit that rotationally agitates the content inside the reactor, comprising:

a rotational shaft that extends in a flow direction in the reactor;

rotatable members that are rotated about the rotational shaft; and

a rotating unit that rotates the rotatable members;

wherein the content flows over each of the partition plates,

wherein in each of the chambers the partition plates are disposed on at least one of an inlet side and an outlet side of each of the chambers,

wherein a top portion of the partition plates act as a weir, and

wherein each of the multiple partition plates has a hole through which the rotational shaft extends so as to dispose the rotational shaft completely inside the content.

2. The chemical reaction apparatus according to claim 1 , wherein an overflow depth at the partition plate on the outlet side is H that is calculated using the following equation:

15 eQ =√{square root over (2 g )} CN{ 4( b−a ) H 5/2 +10 aeH 3/2 }

(where Q is a flow rate, a is a width of a bottom of a trapezoidal flow path, b is a width of an upper side of the trapezoidal flow path, e is a height from the bottom to the upper side of the trapezoidal flow path, C is a flow coefficient, N is a number of the trapezoidal flow paths formed at one partition plate, and g is an acceleration of gravity).

3. The chemical reaction apparatus according to claim 1 , wherein the unfilled space is between a surface of the liquid content and a transmission end of the at least one waveguide, and

wherein the unfilled space is continuous over the multiple chambers.

4. The chemical reaction apparatus according to claim 1 , wherein at least two chambers of the multiple chambers are uninterrupted by partition plates.

5. The chemical reaction apparatus according to claim 1 , wherein:

the horizontal flow reactor further comprises a bottom face, and

the rotational shaft is parallel to the bottom face.
