Abstract

The present invention relates to a reactor, and according to one aspect of the present invention, there is provided a reactor comprising a housing provided with a reaction space, a tube disposed inside the housing, an impeller provided inside the housing to allow reactants in the reaction space to flow into and out of the tube and a nozzle provided to spray a liquid from the reaction space toward the housing wall surface side.

First claim

The invention claimed is:

1. A reactor comprising:
a housing provided with a reaction space;
a tube disposed inside said housing;
an impeller provided inside the housing to allow reactants in the reaction space to flow into and out of the tube; and
a nozzle provided to spray a liquid from the reaction space toward the housing wall surface side,
wherein the nozzle is provided such that a jetting port is located at 5% or less of the distance between the housing wall surface and the tube, and
wherein the nozzle is provided along the circumferential direction of the tube.

2. The reactor according to claim 1 , wherein the nozzle is provided to spray the liquid toward the housing wall surface side after being extended from the housing wall surface toward the tube side.

3. The reactor according to claim 2 , wherein the nozzle is provided to have a bent part.

4. The reactor according to claim 1 , wherein the reactor is provided such that in the reaction space, a crystallization reaction takes place, and
the nozzle sprays the liquid for eliminating crystallization heat.

5. The reactor according to claim 4 , wherein the nozzle is provided so that vapor generated by vaporization of the liquid sprayed from the nozzle during the crystallization reaction rises adjacent to the wall surface of the housing.

6. The reactor according to claim 1 , wherein the tube has a hollow opening along the height direction of the housing.

7. The reactor according to claim 6 , wherein the impeller is disposed inside the tube.

8. The reactor according to claim 6 , wherein the tube is provided such that the diameter increases or decreases at any one of the upper end and the lower end.
