Title: Dry type waste gas desulfurization system
Inventor: SETO HIROSHI
IPC: B01D53/60
Filed: 2002-02-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a dry type system for desulfurization, denitrification, and dust collection which is sufficiently competitive with a wet type desulfurization system in cost.  <P>SOLUTION: A wet type method which uses a large amount of water is widely used in waste gas desulfurization. A dry type desulfurization system is free from defects such as the large amount of water used. A conventional dry type desulfurization system uses a particulate desulfurizing agent and must reduce gas flow rate for suppressing pressure drop, thus a moving bed of a solid-gas reactor is large-sized. The production cost of a particulate desulfurizing agent is prone to be increased. Accordingly, the particulate absorbing agent used in the conventional dry waste gas desulfurization system is made into a powder desulfurizing agent so as to eliminate the process of granulation, thus the decrease in yield is not necessary to be considered. By powdering of the absorbing agent, a multistage spouted bed and the moving bed are applied to the solid-gas reaction of the waste gas with an absorbing agent, thus increasing the flow rate of the waste gas. This dry type system is made into an economical waste gas desulfurization system by the decease in cost due to downsizing of the system and a composite function of a desulfurization, denitrification and dust collection system.  <P>COPYRIGHT: (C)2003,JPO
