Heat exchanger with cold fluid and hot fluid not leak through with each other

Abstract

The invention discloses a heat exchanger with a cold fluid and a hot fluid not leak through with each other. The shell side of a high-position cold fluid container (1) passes through the cold fluid. The shell side of a low-position hot fluid container (3) passes through the hot fluid. A hot fluid inlet (9) and a hot fluid outlet (10) are respectively installed at the top and the bottom of the hot fluid container (3). A cold fluid inlet (11) and a cold fluid outlet (12) are respectively installed at the top and the bottom of the cold fluid container (1). A condensation heat exchange tube (2) is arranged in the cold fluid container (1). An evaporation heat exchange tube (4) is arranged in the hot fluid container (3). The lower end of the condensation heat exchange tube (2) is connected with the lower end of the evaporation heat exchange tube (4) through a condensed liquid return tube (5) and the upper end of the condensation heat exchange tube (2) is connected wit the upper end of the evaporation heat exchange tube (4) through a steam ascending tube (6) to form an independent closed circulation loop. The cold fluid and the hot fluid respectively pass through two containers, the occurrence of mutual leakage between the cold fluid and the hot fluid is absolutely avoided and the operation safety of the equipment is ensured.

Description

technical field [0001] The invention relates to the field of industrial equipment manufacturing such as petroleum, chemical industry, food, metallurgy and the field of chemical process, and more specifically relates to a heat exchanger for cold and hot fluids without leakage. Background technique [0002] Heat exchangers are important industrial general-purpose equipment widely used in processes such as evaporation, condensation, cooling, and heating. Traditional heat exchangers are classified in form: tube heat exchangers, casing heat exchangers, jacket heat exchangers, plate heat exchangers, etc. The common feature of these traditional heat exchangers is that heat is exchanged through a layer of partition wall. One side of the partition wall is hot fluid, and the other side of the partition wall is cold fluid. Once the partition wall has defects such as cracks and perforations, it will inevitably cause the two fluids to interact. leakage. In many industrial production pr...
