Problems solved by technology

Sometimes the height of the upper tower of the rectification tower is increased due to the design of the opening of the dirty nitrogen gas. At the same time, the actual number of packing plates of the pure nitrogen tower is more than required due to the increase of the height of the upper tower of the rectification tower. The number of theoretical packed trays, resulting in an increase in the overall transport height of the rectification column (the upper column of the rectification column is usually transported together with the pure nitrogen column)

Abstract

The invention discloses an air separation device. The device at least comprises a rectifying tower, the rectifying tower comprises a first tower body and a second tower body, the first tower body is arranged on the second tower body, the diameter of the first tower body is smaller than that of the second tower body, the first tower body and the second tower body are connected through a conical seal head, and at least one open hole is formed in the conical seal head.

Description

technical field [0001] The invention belongs to the field of pressure equipment, and in particular relates to an air separation device. Background technique [0002] The head is an indispensable and important part of pressure vessel equipment in many industries from petrochemical, atomic energy, to food, pharmaceutical and so on. The head is an important part of the equipment. It is connected with the cylinder to form the shell of the equipment. The head and the cylinder can be directly welded to form a non-detachable connection. The advantage of this connection method is that the connection cost is low, The sealing performance is good, and the leakage accident in the production process is not easy to occur. [0003] As a part of the container, the head can be divided into spherical, oval, dish, spherical crown, conical shell and flat cover according to the geometric shape and different fields of application. The head is also collectively referred to as the convex head, wh...
