Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature heat exchangers, in particular to a shell cooling device for a high-temperature heat exchanger. Background Art

[0002] Shell and tube air preheater is an important energy-saving equipment. It has been widely used in the energy-saving recovery of waste heat in chemical, steel, power generation, carbon black and other industries. According to the different requirements of each industry, the maximum operating temperature can reach about 1100℃. The heat exchange tubes, tube sheets and shells are the main components of shell and tube air preheaters. The selection of materials plays a vital role in the use of the equipment. With the development of society, the application of shell and tube air preheaters has become more and more extensive. Therefore, the demand for a shell cooling system structure for high-temperature heat exchangers is growing.

[0003] The existing shell and tube air preheater cannot cool the shell when operating at high temperature for a long time, causing the shell to be in a high temperature state for a long time. There is a great risk when using the equipment. In addition, since the temperature of the high-temperature air is too high, the shell temperature is high. After the cooling device contacts the shell, the temperature will rise rapidly, resulting in poor cooling effect on the shell. Therefore, a shell cooling system structure for a high-temperature heat exchanger is proposed to address the above problems. Utility Model Content
