[0002] During the use of steam boilers, due to long-term use, the hot water used in the steam boiler has a high impurity content. It is necessary to discharge the high-temperature wastewater with high impurity content and replace it with new water for continued use. Therefore, the treatment of wastewater is usually an important step.

[0003] However, due to the high temperature and high pressure characteristics of sewage, direct discharge not only wastes a lot of heat energy, but also may cause thermal pollution to the environment. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-3 , a sewage soft water tank for a steam boiler, comprising a box body 1, a water inlet pipe 2 connected to the outer side of the box body 1 is provided on the upper side, a water outlet pipe 14 connected to the outer side of the box body 1 is provided on the lower side, and a drain valve is provided on the outlet pipe 14; connecting pipes 3 are inserted through the top and bottom of the box body 1, and the two connecting pipes 3 are connected to the box body 1 by rotation, and rotary joints 4 are connected to the two connecting pipes 3 and located on the outer side of the box body 1, and the two rotary joints 4 are respectively connected to a sewage pipe 5 and a sewage pipe 6, the sewage pipe 5 is connected to the steam boiler, and the sewage pipe 6 is connected to the collection equipment; a heat exchange tube 7 is provided in the box body 1, and the top and bottom of the heat exchange tube 7 are respectively connected to the two connecting pipes 3, and a support leg 13 is provided at the bottom of the box body 1, and an anti-slip pad is provided at the bottom of the support leg 13.

[0025] The above structure: When in use, the sewage pipe 5 is connected to the steam boiler, and the high-calorie sewage enters the heat exchange tube 7 in the box body 1 through the sewage pipe 5 and the connecting pipe 3. At the same time, soft water is introduced into the box body 1 through the water inlet pipe 2, so that the high-temperature sewage in the heat exchange tube 7 exchanges heat with the soft water. The sewage temperature is reduced and then discharged, which reduces thermal pollution. At the same time, the soft water is heated, reducing additional heating energy consumption.

[0026] Example 2

[0027] Based on the above embodiment, the heat exchange tube 7 is a continuously curved, upward-curving serpentine tube, increasing the heat exchange area. A drive mechanism 8 is provided at the top of the housing 1 to rotate the connecting tube 3 and the heat exchange tube 7. This drive mechanism 8 rotates the connecting tube 3 and the heat exchange tube 7, enabling a dynamic heat exchange process. The rotating heat exchange tube 7 continuously changes the angle and position of contact with the soft water, making the heat exchange more uniform and efficient. Furthermore, the rotating heat exchange tube 7 enhances the turbulent flow of the fluid at the bottom of the tube, further disrupting the thermal boundary layer and improving heat exchange efficiency.

[0028] Specifically, the drive mechanism 8 includes a support plate 81 fixedly mounted on the top of the housing 1. A drive motor 82 is fixedly mounted on the support plate 81. The output shaft of the drive motor 82 is fixedly connected to a driving gear 83. A follower gear 84 is sleeved on the connecting pipe 3 and fixedly connected to the driving gear 83. The driving gear 83 meshes with the follower gear 84. The drive mechanism 8 rotates the driving gear 83 through the drive motor 82. The meshing transmission of the follower gear 84 causes the connecting pipe 3 to rotate, which in turn drives the heat exchange tube 7 to rotate, thereby improving heat exchange efficiency.

[0029] In addition, in order to increase the stability of the heat exchange tube 7, an annular block 9 is fixedly connected to the box body 1, and a slide groove 10 is opened on the inner side of the annular block 9. A sliding ball 11 is slidably connected in the slide groove 10, and a connecting rod 12 is fixedly connected to the sliding ball 11. The connecting rod 12 is fixedly connected to the heat exchange tube 7.

[0030] Furthermore, the first sewage pipe 5 is located below the housing 1, while the second sewage pipe 6 is located above it. This design allows the hot sewage to enter from the bottom and gradually flow upward, creating a temperature gradient. This temperature gradient causes the sewage to gradually cool as it flows, exchanging heat with the soft water flowing from top to bottom. The existence of the temperature gradient makes the heat exchange process more efficient because the hot sewage first comes into contact with the cooler soft water, which transfers heat more quickly.

[0031] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
