Precautions for pearlite filling in air separation unit

on the tower on the section of the sealing plate and pure nitrogen export cap, coarse argon tower condenser coarse argon export cap must be removed on the ground, clear clean aluminum chips with clean white cloth or plastic wrap before lifting in place. During the lifting of aluminium pressure vessels and aluminium pipelines, the installation should take protective measures to prevent damage to the surface, such as rigging jacket rubber tube, rigging between with support to open.

At present, there are two types of common condensing evaporators in domestic air separation units, plate fin condensing evaporator and tubular condensing evaporator. Tubular condensing evaporator is divided into three types: long tube, short tube and coil. The long tube and short tube are all in row. The tube is made of red copper and the tube sheet is made of brass. It is generally used in small and medium-sized air separation plants. Coil type is generally used for auxiliary condensing evaporator. Because there is no fixed liquid level in the coil, the heat transfer coefficient is small, so it has been gradually eliminated. The plate fin condenser evaporator is made of all aluminum structure, and the plate unit is arranged in vertical star shape. Its characteristics are compact structure, light weight, small volume and easy to manufacture. It is widely used in large and medium air separation plants. Due to the gradual enlargement of the air separation unit, the heat excha
