Self-cleaning method of circulating fluidized bed with multiple vertical tubes with solid particle storage tank and its self-cleaning type circulating fluidized bed with multiple vertical tubes

摘要

the present invention is a solid particle storage tank equipped with a circulating fluidized bed heat exchanger Tube of self-cleaning method and that relates to a self-cleaning type circulating fluidized bed heat exchanger is tubular, its object is provided with a solid particle storage tank in the lower part of the circulating fluidized bed heat exchanger is installed groups tubular perforated plate, by putting the solid particles are stored using a screw-in passage of the exhaust gas flowing , the tubular circulating fluidized bed heat exchanger of the solid particles are suspended during startup of the trial and if ever collided with the fouling problem solving around the hole in the trial, and the solid particles having a storage tank Tube circulating fluidized bed heat exchanger itself cleaning method and to provide an self-cleaning type circulating fluidized bed heat exchanger is tubular. ever configuration of the present invention is the groups in a tubular circulating fluidized bed heat exchanger, located on the lower side of the body of the porous plate storage the solid particles and a solid particle storage tank; The solid particles are stored in the solid particle storage tank to the storage tank screw feeder to feed the ever rich exhaust gas inlet; including further, solid particles are suspended portion ever configured at start-up to remove the fouling lower solid particle collides with the perforated plate The self-cleaning type circulating fluidized bed heat exchanger Tube self-cleaning method using the same tile with a storage tank with features of the invention. ;
