Abstract

A chemical reaction apparatus includes: a horizontal flow-type reactor inside of which has been partitioned into multiple chambers by a partition plate, 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 reactor has a shape in which an area of a liquid surface does not change even in a case where a height of the liquid surface changes according to a change in an amount of the content.

First claim

The invention claimed is:

1. A chemical reaction apparatus, comprising:
a horizontal flow reactor inside of which has been partitioned into multiple chambers by a partition plate, and in which 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;
at least one agitation unit that rotationally agitates the content inside the reactor, comprising:
a rotational shaft that extends in a liquid content flow direction in the reactor;
at least one rotatable member that is rotated about the rotational shaft; and
a rotating unit that rotates the at least one rotatable member; and

a reactor outlet disposed at a height above the rotational shaft maintaining a surface of the liquid content above the rotational shaft,
wherein the unfilled space is between the liquid surface and a transmission end of the at least one waveguide,
wherein the unfilled space is continuous over at least two of the multiple chambers, and
wherein the reactor has a shape in which an area of the liquid surface does not change even in a case where a height of the liquid surface changes according to a change in an amount of the content, and
wherein the reactor shape further comprises the area in a liquid surface direction that is unchanging above the rotational shaft.

2. The chemical reaction apparatus according to claim 1 , wherein the reactor shape is such that the area of the liquid surface does not change according to the change in the amount of the content, as long as the amount of the content is within a predetermined range.

3. The chemical reaction apparatus according to claim 1 , wherein the reactor has, below the rotational shaft, a semicylindrical shape elongated in the flow direction and projecting downward.

4. The chemical reaction apparatus according to claim 1 , wherein the reactor can be opened and closed above the unfilled space.
