DIGESTIVE GAS CLEANING APPARATUS AND GAS TURBINE POWER GENERATION EQUIPMENT USING DIGESTIVE GAS

摘要

PPROBLEM TO BE SOLVED: To improve durability of apparatuses by cleaning a digestive gas. PSOLUTION: The digestive gas obtained from a sewage-treatment plant 11, etc., is supplied to a desulfurization column 12. The desulfurization column 12 is packed with an iron oxide as a desulfurizing agent, the iron oxide in the desulfurization column 12 is reacted with hydrogen sulfide in the supplied digestive gas component to form iron sulfide and the digestive gas is desulfurized. The digestive gas is introduced into dehumidifier main bodes 13a and 13b and water in the digestive gas is adsorbed on contact materials 17a and 17b packed with or supporting a dehumidifying agent held in the dehumidifier main bodies 13a and 13b. Water adsorbed on the contact materials 17a and 17b is released, for example, from a regeneration valve 19b to the outside by closing one of the regeneration valves 19a and 19b and supplying air from a four-way valve 14 to the dehumidifier main bodies 13a and 13b by a pump 16. These actions are alternately carried out. PCOPYRIGHT: (C)2004,JPO
