摘要： PROBLEM TO BE SOLVED: To provide a carbon dioxide liquefying apparatus capable of saving energy. SOLUTION: This carbon dioxide liquefying apparatus 1 includes a pressure-increase dehumidifying apparatus 10 for pressure-increase a gas mixture Gm, containing carbon dioxide as the main component and steam for removing moisture; a cooler 21 for cooling the gas mixture Gm by a cooling medium F; a moisture condenser 41; a dehumidifier system 50 for generating a dehumidified carbon dioxide gas Gdh; with the moisture concentration of the gas mixture Gm being reduced to a prescribed concentration; and a carbon dioxide condenser 42 for cooling-condensing the dehumidified carbon dioxide gas Gdh for generating liquefied carbon dioxide Ln. The moisture condenser 41 cools the gas mixture Gm to a prescribed temperature which is higher than the condensing temperature of carbon dioxide, and the moisture in the gas mixture Gm can be condensed. The moisture is removed by the moisture condenser 41, before introducing the gas mixture Gm into the dehumidifier system 50, and a dehumidifying load is thereby reduced in the dehumidifier system 50 and energy is saved.

摘要： PROBLEM TO BE SOLVED: To provide a pump and a disassembling method of pump shaft water- sealing part capable of easily assembling/breaking down a pump water-sealing part mounted to a pump shaft even without removing an impeller. SOLUTION: A hub 3 of an impeller 1 is divided to a part 3-2 fixed to the impeller 1 side and a part 3-1 fixed to a pump shaft 2 side. The hub 3-1 fixed to the pump shaft 2 side and a shaft end fitting 41 are only removed in the state that the impeller 1 is fixed to an own position by a fixing means separately prepared. A maintenance of a mechanical seal (pump water-sealing part) 15 at a pump shaft 2 end exposed is carried out. Thereafter, the hub 31 and the shaft end fitting 41 are only mounted again. Therefore, since it is not necessary that the impeller 1 is removed to another place, the maintenance of the mechanical seal 15 can be easily carried out.
