The fixing holes 901 are inserted into the heat transfer tube bundle 7.
[0024] The liquid, such as dyeing liquid or washing water, which needs to be heated, enters the liquid inlet chamber 101 through the liquid inlet pipe 2 and then enters the heat transfer pipe bundle 7, the steam enters the heat transfer pipe main body 1 through the first shell side pipe 4, heats the heat transfer pipe bundle 7, and then the steam is discharged from the heat transfer pipe main body 1 through the second shell side pipe 5, the temperature of the heated steam is reduced to generate condensed water in the heat transfer pipe main body 1, the condensed water is discharged through the blowdown valve 6, and the heated liquid flows out of the heat transfer pipe bundle 7 to the liquid outlet chamber 103 and then flows out of the elution machine cylinder through the liquid outlet pipe 3.

[0026] The arrangement of the baffle plates 8 can block the steam from being directly discharged from the second shell side pipe 5, due to the upper-lower staggered arrangement of the two groups of baffle plates 8 and the partial overlap of the end portions of the two groups of baffle plates 8, the steam is forced to pass through the heat transfer pipe bundle 7 multiple times in a transverse direction according to the arrangement of the baffle plates 8, the disturbance of the steam in the heat transfer pipe main body 1 is enhanced, the heating effect of the steam on the heat transfer pipe bundle 7 is improved, and the residence time of the steam in the heat pipe main body is prolonged to make the heating effect of the steam on the heat transfer pipe bundle 7 better.
