Title:
DEVICE FOR EXECUTING PHYSICAL AND/OR CHEMICAL TREATMENT AND METHOD OF OPERATING SAID DEVICE
Document Type and Number:
Japanese Patent JPS6089686
Kind Code:
A
Abstract:
This invention relates to apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger (10) of the continuous type, comprising a large number of vertical heat exchanger tubes (18) mounted between a lower chamber (17) and an upper chamber (16) within a jacket (15). Within the tubes (18) small solid particles are kept in a fluidized condition by the fluid medium passing up from the lower chamber (17) through the tubes (18), so as to achieve a good heat transfer, whereas also any deposit will be removed from the innertube walls. Forthe downward flow of the granular mass at least one return tube (21) is provided. Downward circulation of the fluid medium through the return tube (21) should be minimal, however, which can be achieved by an increase of the pressure difference between the upper and lower chamber (16; 17), which increase of the pressure difference can be achieved by fitting several distribution plates (24; 42) at a level above the return tube (21) outlet into the lower chamber (17), preferably so thatthe apertures in the various distribution plates (24; 42) of the multiple design are not vertically in line.The second distribution plate (42) also serves to minimise excessive wear of the material of the jacket (15) due to the eddying motion of the granules.
