Abstract

A continuous flow reactor without any moving parts to facilitate solid-liquid reaction without clogging is disclosed herein. It comprises plurality of identical cavities in series/sequence, each cavity being provided with: a pair of inlets at the top to allow entry of reactants into the reactor; an outlet at the bottom to allow the reactants to the next cavity for mixing; and a jacket covering around the cavities to provide heating or cooling effect as per the requirement. The outlet of the previous cavity is inclined at a suitable angle relative to the outlet of the next cavity to prevent clogging and facilitate efficient mixing of the reactants.

First claim

The invention claimed is:

1. A solid continuous flow reactor assembly to facilitate a solid-liquid suspension without clogging, comprising of:
a. a flow reactor;
b. a pair of inlets at a top side of the flow reactor;
c. an outlet at a bottom side of the flow reactor;
d. identical cavities arranged in series/sequence inside the flow reactor, wherein a first cavity included in the identical cavities is coupled with the pair of inlets at the top side of the flow reactor, and wherein the first cavity includes an outlet that opens into a second cavity included in the identical cavities, wherein the pair of inlets at the top side of the flow reactor are configured with the first cavity to allow entry of reactants into the flow reactor; and
e. a jacket covering the identical cavities is configured to provide a heating or cooling effect.

2. The solid continuous flow reactor assembly as claimed in claim 1 , wherein an angle between an inlet and an outlet in each of the identical cavities is in a range of 30°-180°.

3. The solid continuous flow reactor assembly as claimed in claim 1 , wherein a bottom surface of each of the identical cavities is selected from hemisphere, flat circular or an asymmetric conical.

4. The solid continuous flow reactor assembly as claimed in claim 1 , wherein the jacket has an inlet close to the outlet at the bottom side of the flow reactor, and wherein the jacket has an outlet close to the pair of inlets at the top side of the flow reactor.

5. The solid continuous flow reactor assembly as claimed in claim 1 , wherein the flow reactor is configured to operate at variable flow rates with solid concentration of 10%-30%.

6. The solid continuous flow reactor assembly as claimed in claim 1 , wherein the flow reactor is adapted to withstand pressure ranging from atmospheric pressure to 100 bar and temperature ranging from −20° C. to 180° C.

7. The solid continuous flow reactor assembly as claimed in claim 1 , wherein numbers of the identical cavities arranged are at least two and maximum of 20.

8. The solid continuous flow reactor assembly as claimed in claim 7 , wherein the identical cavities each have a radius, wherein a distance of an outlet of each identical cavities from a central axis of the flow reactor is in a range of 0.4-0.8 the radius of the identical cavities.
