SOLID-STATE HEAT EXCHANGER MODULE

Abstract

The invention relates to a novel solid heat exchanger module containing a plurality of heat exchanger tubes having a particular shape and being arranged in a special manner.

Claims

1. A solid state heat exchanger module comprising (i) a closed housing for receiving heat exchanger tubes; (ii) a plurality of heat exchanger tubes; (iii) at least one substance inlet; (iv) at least one substance outlet; (v) pipe connections between the heat exchanger tubes for supply with heating or cooling media, in which (a) the heat exchanger tubes are grouped in bundles, each offset from one another, (b) each module contains 2 to 10 bundles, (c) each bundle contains 10 to 100 tubes, (d) each tube has a rectangular or rhombic cross-section with rounded edges with the angles , , and , for which angle the selection conditions apply, and =30 to 120 =60 to 150 =30 to 120 =60 to 150 with the proviso that the sum of all angles gives 360 e) the distance D1 between each two adjacent heat exchanger tubes in a row and the distance D2 between each two adjacent heat exchanger tubes in two adjacent rows is independently between 10 and 100 mm.

2. The module of claim 1, wherein the heat exchanger tubes in the bundles each offset to each other are arranged in 2 to 10 rows.

3. The module of claim 1, wherein the heat exchanger tubes in the bundle each have a diameter d1 in the range of 20 to 100 mm.

4. The module of claim 1, wherein the heat exchanger tubes are connected via a distributor for receiving the heating or cooling liquid.

5. The module of claim 1, wherein the heat exchanger tubes are heated or cooled with liquids, vapors, steam, gases, cooling water and corresponding mixtures.

6. The module of claim 1, wherein the heat exchanger tubes are heated with unpurified vapors.

7. A solid state heat exchanger comprising at least two modules according to claim 1.

8. The heat exchanger of claim 7, wherein said modules are interconnected via boxes.

9. The heat exchanger of claim 1, wherein said modules can be overturned in said boxes.

10. The heat exchanger of claim 1, wherein said modules are movable and extendable via rolls.

11. A method for the treatment of free-flowing bulk material, comprising (a) providing the solid state heat exchanger of claim 7, (b) feeding said bulk material to the inlet of said heat exchanger, and (c) collecting the treated bulk material from the outlet of said heat exchanger.

12. The method of claim 11, wherein the bulk material is selected from the group consisting of seeds, sands and polymer grits.

13. (canceled)
