<p>PURPOSE:To miniaturize a water remover and to reduce the weight of CO2 removing device by using the water remover containing an electrochemical cell provided with a solid electrolysis chamber, electrodes, a reaction chamber for removing water and a reaction chamber for recovery of water. CONSTITUTION:In the CO2 removing device consisting of two systems, the water content in a gas to be treated introduced to the reaction chamber 1d1 for removing water is allowed to react on the interface of the electrode 1e1 as shown in equation I. The produced O2 is accompanied with the gas flow and introduced to a heat exchanger of a 1st system and cooled. The cooled gas is sent to an adsorption tower, and CO2 is adsorbed and removed by a molecular sieve, and then introduced to the reaction chamber 1d2 for the recovery of the water. On the other hand, H<+> in the equation I reaches the electrode 1e2 from the inside of the solid electrolysis chamber 1f and is allowed to react with O2 in the reaction chamber 1d2 for the recovery of water, and water is produced as shown in equation II. And the treated gas deprived of CO2 and recovered with water is again sent to a chain. In the 2nd system, CO2 is desorbed by heating the molecular sieve. Thus, by alternatively using the 1st and the 2nd systems, the adsorption of CO2 and the regeneration are continuously carried out.</p> |
