The two ends of the heat exchange tubes 3 are fixed to the two tube sheets 2, and the two ends of the heat exchange tubes 3 are connected to the left cylinder 11 and the right cylinder 12, respectively. Cold water enters the right cylinder 12 through the cold water inlet 16 and finally enters the heat exchange tubes 3.

Heat medium is introduced into the intermediate cylinder 13 through the heat medium inlet 18, and the heat medium exchanges heat with the cold water in the heat exchange tube 3. The cold water after heat exchange is heated and flows to the left cylinder 11 through the heat exchange tube 3, and is finally heated into steam and discharged through the steam outlet 17 connected to the left cylinder 11. At the same time, the temperature of the heat medium after heat exchange decreases and flows out through the heat medium outlet 19.

[0022] Several upper baffles 4 and lower baffles 5 are evenly arranged on the inner wall of the intermediate cylinder 13. The upper baffles 4 and lower baffles 5 are used to guide the flow of the heat medium. Figure 3 As shown, the upper baffle 4 and the lower baffle 5 are alternating arc-shaped plates, and the alternating upper baffle 4 and lower baffle 5 form an S-shaped path, which can extend the flow path of the heat medium, enhance the turbulence effect, and improve the heat exchange efficiency.

[0023] The top of the intermediate cylinder 13 is provided with a thermometer interface 112, a pressure gauge interface 113 and a lifting lug 111. The thermometer interface 112 is used to connect a thermometer and the pressure gauge interface 113 is used to connect a pressure gauge, so as to facilitate the observation of the temperature and pressure inside the intermediate cylinder 13. The lifting lug 111 is arranged symmetrically on both sides of the top of the intermediate cylinder 13, so as to facilitate the hoisting of the entire device.

[0024] The bottom of the intermediate cylinder 13 is provided with saddle supports 6. The saddle supports 6 are arranged symmetrically on both sides of the bottom of the intermediate cylinder 13. Each set of saddle supports 6 has an anti-slip pad layer at the bottom, which can provide stable support for the device.

[0026] Manholes 110 are provided on the left cylinder 11 and the right cylinder 12 respectively, which facilitates the cleaning of the interior.

[0027] In use, cold water enters the right cylinder 12 through the cold water inlet 16 of the right end cap 15 and flows to the left cylinder 11 through the heat exchange tube 3; the heat medium enters the shell side of the middle cylinder 13 through the heat medium inlet 18 and is guided by the upper baffle 4 and the lower baffle 5 to form an S-shaped flow path, and fully exchanges heat with the outer wall of the heat exchange tube 3; after absorbing heat, the cold water vaporizes and the steam is discharged through the steam outlet 17, and the cooled heat medium flows out through the heat medium outlet 19.
