Abstract
The invention relates to a liquid to solids heat exchanger and to a process for retorting carbon-containing solids (e.g. oil shale) using such heat exchanger. The heat exchanger contains a liquid pool reservoir, heat source or heat sink for heating or cooling the liquid pool, a support for the solids such that there is heat exchange between the solids and the liquid pool without direct contact of the solids and the liquid pool, and oscillators or vibrators to cause the solids to be conveyed while exchanging heat with the liquid pool.
Claims25
A liquid to solids heat exchanger wherein there is no direct contact between the liquid and the solids comprising:
- (a) a liquid pool within a reservoir;
- (b) means for heating or cooling said liquid pool;
- (c) at least one wall having side walls, said wall having a top surface and a bottom surface, said wall with said side walls being immersed in said liquid pool such that the bottom surface but not the top surface is in contact with the liquid pool;
- and
- (d) means for imparting an oscillatory motion to said wall relative to said reservoir thereby causing any solids present on said top surface to be conveyed along the top surface while exchanging heat with the liquid pool.
A liquid to solids heat exchanger wherein there is no direct contact between the liquid and the solids comprising:
- (a) a liquid pool within a reservoir;
- (b) means for heating or cooling said liquid pool;
- (c) at least one wall for supporting the solids, said wall having a top surface and a bottom surface, a duct communicating with and disposed beneath said bottom surface such that the bottom surface forms a closure for one end of the duct, the other end of the duct being immersed in said liquid pool such that the bottom surface but not the top surface of said wall is in contact with the liquid pool and the level of the liquid pool within the duct is at a higher elevation than the level of the liquid pool outside the duct;
- and
- (d) means for imparting an oscillatory motion to said wall relative to said reservoir thereby causing any solids present on said top surface to be conveyed along the top surface while exchanging heat with the liquid pool.
