Claims

[Scope of Claim for Utility Model Registration] 1. Condenser blocks are provided in multiple stages in a condenser that exchanges heat between nitrogen gas and limb oxygen, which is installed between the upper and lower tubes of a double rectifier tube of a large air separation device. , the nitrogen gas in the lower cylinder is piped upward to the top of the condenser block at each stage, and the pipes that lead the liquid nitrogen condensed in the condenser to the lower cylinder are installed at the bottom of each stage condenser block, and the pipes are installed around the condenser block at each stage. A partition liquid reservoir is defined, and the upper and lower ends on the liquid oxygen side of the heat transfer fin portion of the condenser block are opened into the liquid reservoir, and the liquid oxygen flows from the upper stage to the center, outer periphery, and next stage of the condenser partition. An overflow duct is provided from the outer periphery to the center of the capacitor block, entering from below the capacitor block and reaching an overflow port at the height where the capacitor block is immersed, so that the flow is constant, and a duct that raises oxygen gas to the inner and outer peripheries of this overflow duct. A condenser for a large air separation device, characterized by being equipped with. 2. A condenser for a large air separation device according to claim 1, wherein a liquid oxygen blow pipe is provided at the bottom of each condenser partition. 3. A condenser for a large air separation device according to claim 1 or 2 of the utility model registration claim, wherein a drain hole is provided at the bottom of each condenser partition.
