Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Such as figure 1 The embodiment of the present invention provides an air separation pre-cooling system, including an air cooling tower 200 and a water cooling tower 100. The air cooling tower 200 is connected with an air inlet pipe 300 at the bottom and an air outlet at the top. The air cooling tower 200 has at least part The tower section is located in the tower cavity of the water cooling tower 100.

[0021] Among them, the air s...

Abstract

The invention relates to a space division precooling system which comprises an air cooling tower and a water cooling tower; an air inlet pipe is connected to the lower part of the air cooling tower; the top of the air cooling tower is provided with an air outlet; and at least a part of tower section of the air cooling tower is arranged in a tower cavity of the water cooling tower. For the space division precooling system provided by the invention, the air cooling tower and the water cooling tower are combined into one, and one tower body can satisfy respective functions of the air cooling tower and the water cooling tower, so that the occupying area of the space division precooling system is obviously reduced, and the system building cost is reduced. As the water cooling tower encloses theouter part of the air cooling tower to exert the cooling effect to the whole body of the air cooling tower, the cooling efficiency and effect of the air cooling tower can be improved, and the cost ofarranging a heat insulation material at the outer part of the whole tower of the air cooling tower can be reduced; and radiation heats produced by illuminating two tower bodies with the sun are reduced in high-temperature summer, and the cooling efficiency of the precooling system is improved.

Description

Technical field [0001] The invention belongs to the technical field of oxygen production, and specifically relates to an air separation precooling system. Background technique [0002] The pre-cooling system is an indispensable part of the air separation system. After filtering and compression, the air temperature is about 100 degrees, and it must be cooled by a set of pre-cooling system before it can enter the downstream purification system and finally undergo rectification and separation. [0003] In the prior art, the pre-cooling system has an air cooling tower and a water cooling tower respectively. The air in the air cooling tower is respectively cooled by circulating water and low temperature chilled water twice; the water cooling tower cools the circulating water or the return water of the low temperature cooling water. The air-cooling tower and the water-cooling tower occupy a large area, and the waterway system has two towers back and forth, and the supporting water pumps...
