Problems solved by technology

This type of heat exchanger is also suitable for using the heat of high-temperature flue gas to heat liquid, but the liquid will evaporate and gasify after being heated, and the volume of gas generated by gasification will increase, and the pressure will also greatly increase
The pressure generated by the gas will stretch the bent plate outward, resulting in damage to the structure of the heat exchanger and making it unable to use normally, so its structure needs to be further improved

Abstract

The invention discloses a pressure resistant heat exchanger comprising a housing. Bent units are arranged in the housing at intervals, are provided with liquid accommodating cavities inside and are provided with liquid inlets and liquid outlets; partitions matching with the bent units in shapes are arranged in the bent units at internals, two sides of the partitions are fixedly connected to first bent plates and second bent plates of the bent units, the partitions are provided with through holes, smoke channels are formed between the adjacent bent units, one ends of the smoke channels are provided with smoke inlets, the other ends are provided with smoke outlets, and the sections of the liquid cavities and smoke channels are in continuous bent structures. The pressure resistant heat exchanger is simple in structure, the bent units are adopted and the liquid cavities and smoke channels in the continuous bent structures are arranged in the housing, structure is compact, and size is small; the pressure resistance of the bent units is improved by arranging the partitions in the bent units.

Description

Technical field [0001] The invention relates to a heat exchange equipment, in particular to a pressure-resistant heat exchanger. Background technique [0002] The heat exchanger is a heat exchange device that transfers part of the heat of the hot fluid to the cold fluid so that the temperature of the fluid reaches the index specified by the process flow, also known as the heat exchanger. [0003] Existing heat exchangers mostly adopt two forms: a shell-and-tube heat exchanger and an immersed serpentine heat exchanger. Shell and tube heat exchanger Heat Exchanger , It is a partition type heat exchanger with the wall surface of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger has a simpler structure and reliable operation; the shell-and-tube heat exchanger has two types of fluids for heat exchange. , A kind of flow inside the tube is called the tube side fluid; the other kind of flow outside the tube is called the shell side fluid. In ...
