The invention relates to the technical field of heat exchangers, and discloses a cold wall jacket type high-temperature gas-gas heat exchanger. The cold wall jacket type high-temperature gas-gas heat exchanger comprises an outer shell, an inlet pipe box is fixedly installed at the top end of the outer shell, an outlet pipe box is fixedly installed at the bottom end of the outer shell, and a heat exchange pipe is fixedly connected between the inlet pipe box and the outlet pipe box. A shell pass is formed between the outer shell and the inner shell, a pipe pass is formed between the inner shell and the heat exchange pipe, the shell pass and the pipe pass are used for circulating low-temperature gas, the heat exchange pipe is used for circulating high-temperature gas, the low-temperature gas and the high-temperature gas flow relatively, the heat exchange mode of cold and hot media is pure countercurrent, the heat transfer efficiency is higher, and the heat exchange effect is improved. When the low-temperature gas flows in the shell pass and the pipe pass, the temperature of the outer shell, the inner shell and the heat exchange pipe can be reduced at the same time, the problem that the thermal expansion difference between the heat exchange pipe and the inner shell and the outer shell is large is solved, use of high-temperature-resistant precious metal of equipment can be reduced, and the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a cold-wall jacketed high-temperature air-gas heat exchanger. Background technique [0002] High-temperature gas cooling generally uses water as the cooling medium, in which the tube side is high-temperature gas, and the shell side is cooling water. Utilizing the large film heat transfer coefficient of the shell-side medium, controlling the shell-side cylinder and the metal wall temperature of the heat exchange tube can effectively reduce the thermal expansion difference between the tube bundle and the shell. [0003] For the harsh working conditions of high-temperature gas-gas heat exchange, the maximum temperature on both sides can reach more than 800°C. Since the medium on the shell side of the tube is high-temperature gas, the metal wall temperature of the shell side of the traditional fixed tube sheet and flexible tube sheet heat exchangers with expansion joints has...
