Description

Technical Field

[0001] The utility model relates to the technical field of circulating water cooling, in particular to an air separation circulating water cooling device. Background Art

[0002] The air separation unit is a set of industrial equipment used to separate the various gas components in the air and produce oxygen, nitrogen, argon and other gases of the air components. The most commonly used air separation method is cryogenic distillation. This method converts air into liquid through compression cycle deep freezing. After cryogenic distillation, oxygen, nitrogen, argon and other gas components are gradually separated and produced from the liquid air according to different boiling points. During the operation of the air separation unit, circulating water will be used to cool the air. In order to save water resources and costs, the circulating water will be recycled. It is necessary to use a cooling device to cool the circulating water to meet the cooling needs of the circulating water for the air.

[0003] The working principle of the cooling device is to make the cooling water carrying heat contact and exchange heat with the air, so that the heat is transferred to the air and taken away. When the existing cooling device is in operation, the circulating water sprays downward from the upper part of the device, and a fan is set on the top of the device. The air flows upward from the lower part of the device. The two contact each other in reverse and exchange heat, but there are often the following problems: the contact time between the circulating water and the air is short, so the heat transfer time is short. When the circulating water falls to the bottom of the device, the circulating water is still not fully cooled, and the overall cooling effect is not good, which cannot meet the cooling requirements of the circulating water; second, the cooling form is single, the circulating water cooling speed is slow, and the cooling efficiency is low. Therefore, it is an objective need to develop an air separation circulating water high-efficiency cooling device with fast cooling speed, high cooling efficiency and good cooling effect.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] According to the utility model, the external air entering the second heat-conducting pipe will exchange heat with the heat-conducting plate, thereby reducing the temperature of the heat-conducting plate.
