Abstract

A reaction apparatus includes first and second reaction material accommodation parts, each of which accommodates a solid, gaseous, or liquid reaction material. A feed pump feeds the reaction material to one or each of the first and second accommodation parts. A reactor mixes the reaction material fed from the feed pump. The reactor is configured to have a cylinder that has a reaction chamber which accommodates the reaction material therein. The reactor has injection ports on which one side of each of the upper portion and lower portion thereof are connected to the first and second reaction material accommodation parts, respectively. A stirring shaft is disposed to be rotatable in the cylinder and stirs the reaction material supplied from the first and second reaction material accommodation parts. A stirring motor provides torque for the stirring shaft.

First claim

The invention claimed is:

1. A reaction apparatus for mixing, comprising:
two or more reactant storage units, each configured to store any one of a solid reactant, a gaseous reactant and a liquid reactant;
two or more pumps configured to pump the reactants stored in two or more of the reactant storage units; and
a reactor configured to mix the reactants pumped by the pumps and comprising:
a stirring shaft disposed rotatably in a cylinder and configured to stir the reactants supplied from the reactant storage units;
the cylinder comprises a reaction chamber configured to receive the reactants, and has inlet ports provided at upper and lower sides thereof, respectively, and connected to the reactant storage units, respectively, such that the reactants from the reactant storage units are supplied at opposing sides of the stirring shaft;
a stirring motor configured to provide a rotational force to the stirring shaft; and
a packed chamber disposed around the reaction chamber and through which a heating medium or a refrigerant circulates, the packed chamber being configured to increase or reduce an internal temperature of the reaction chamber wherein one of the reaction products comprises water and further comprising a water removal unit disposed at an outlet side through which a reaction product produced by mixing of the reactants in the reactor is discharged, and configured to remove water from the reaction product discharged from the reactor wherein the water removal unit is a centrifugal hydroextractor or a concentrator.

2. The reaction apparatus of claim 1 , further comprising a check valve disposed between the reactor and the pumps.

3. The reaction apparatus of claim 1 , wherein the solid reactant is stored in a first reactant storage unit; and the reaction apparatus further comprises, between the first reactant storage unit and the reactor, a metering unit configured to meter and feed the solid reactant, and a feeder configured to feed the reactant to the reactor, and between a second reactant storage unit and the reactor, a pump and a flow control valve.

4. The reaction apparatus of claim 3 , wherein the metering unit comprises a load cell.

5. The reaction apparatus of claim 3 , wherein the metering unit comprises a control unit configured to electronically control a degree of metering.

6. The reaction apparatus of claim 1 , further comprising a flow control valve disposed between the pumps and the reactor, in which a degree of opening of the flow control valve is electronically controlled by a control unit.

7. The reaction apparatus of claim 1 , wherein the inlet ports have a Venturi tube shape whose inner diameter gradually decreases toward inside of the reactor.

8. The reaction apparatus of claim 1 , further comprising a pressure control valve disposed above an outlet port of the reactor and configured to control an internal temperature of the reaction chamber.
