Abstract
The present invention relates to a heat exchanger (1) for a solid bulk material, comprising a casing (2), a treatment space (6) located within the casing (2) and having the form of a substantially vertically oriented hollow cylinder, wherein the hollow cylinder is limited by an inner cylinder wall (5) and by an outer cylinder wall (9), wherein the inner cylinder wall (5) and the outer cylinder wall (9) are gas-permeable, but the particles of the solid bulk material cannot substantially pass through the cylinder walls (5, 9), and the inner cylinder wall (5) has a height (h1) which is greater than the height (h2) of the outer cylinder wall (9).
Claims15
A heat exchanger for a solid bulk material, comprising
- a jacket,
- a treatment chamber arranged within the jacket, which is connected to a product inlet in an upper region of the heat exchanger and at least one product outlet in a lower region of the heat exchanger and has a shape of a substantially vertically aligned hollow cylinder, wherein the hollow cylinder is delimited by an inner cylinder wall and by an outer cylinder wall,
- an inner cylindrical gas chamber-within the inner cylinder wall of the treatment chamber, which is connected to a gas inlet,
- an outer hollow cylindrical gas chamber between the outer cylinder wall of the treatment chamber and the jacket of the heat exchanger, which is connected to a gas outlet,
- wherein the inner cylinder wall and the outer cylinder wall are gas-permeable, but the particles of the solid bulk material cannot pass through the cylinder walls,
- wherein the inner cylinder wall has a height h1 which is greater than a height h2 of the outer cylinder wall.
