Description

Technical Field

[0002] A steam drum is a device used in a steam power system, usually used to store and distribute steam. It is a large pressure vessel for storing thermal energy. A steam drum is usually welded from steel plates, and has one or more compartments inside for containing water and steam. Steam drums are widely used in thermal power plants, petrochemicals, papermaking, textiles, printing and dyeing, food and other industrial fields. Most of the existing steam drums are fixed by welding with steel plates, and the scale attached to the inside is difficult to remove during long-term use, affecting the subsequent maintenance costs. At the same time, when cold water meets heat to generate steam, it will increase the pressure inside the steam drum. The existing steam drum lacks a buffer structure to buffer the rapidly rising air pressure. Excessive pressure can easily cause deformation of the external shell, shortening the service life of the steam drum. Therefore, it is necessary to design a steam drum with a new structure.
