Fixed tube-sheet heat exchange equipment

Shell and tube heat exchangers have many advantages. First of all, it has the characteristics of high heat transfer efficiency. The design of the tube and the shell makes the heat transfer area large, and can provide an effective heat transfer path, so that the heat can be fully transferred. Secondly, the shell and tube heat exchanger has the advantages of stable structure and strong reliability. Because of its relatively simple structure, long service life, and relatively easy maintenance and maintenance. Again, shell and tube heat exchangers are also compact. Compared with other types of Pressure Vessel, shell and tube heat exchangers take up less space with the same heat transfer effect.

Shell and tube heat exchangers are used in a wide range of applications. In the chemical industry, metallurgy, electric power, petroleum, papermaking, food and other fields, the application of shell and tube heat exchangers is as extensive as Universal Valve. For example, in oil refineries, shell and tube heat exchangers are commonly used in the heating and cooling of crude oil. In power plants, shell and tube heat exchangers are used for heat transfer between boilers and condensers. In addition, shell-and-tube heat exchangers can also be used in waste gas waste heat utilization, air conditioning systems, industrial recycling, etc.

However, shell and tube heat exchangers also have some problems. First of all, its structure is relatively complicated, and the cost of manufacturing and maintenance is relatively high. Secondly, due to the accumulation of errors, the heat transfer effect is often slightly reduced. In addition, the self-cleaning ability of the shell-and-tube heat exchanger is poor, and problems such as scaling and biological growth are prone to occur, which affects the heat transfer effect.
