[0025] This utility model embodiment provides an industrial waste liquid evaporation heat recovery device, such as... Figure 1-5As shown, the industrial waste liquid evaporation heat recovery device includes: a heat exchange tube 2 disposed within a mounting shell 1 for heat exchange and recovery of the evaporation heat of the industrial waste liquid; a cleaning tube 3 rotatably installed within the mounting shell 1 for cleaning the heat exchange tube 2; a connecting pipe 5 fixedly installed on the mounting shell 1, a flexible hose 4 connected to the connecting pipe 5, and the flexible hose 4 communicating with the cleaning tube 3; and an adjustment mechanism assembled on the mounting shell 1 and the cleaning tube 3 for adjusting the angle at which the cleaning tube 3 cleans the heat exchange tube 2.

[0026] In this embodiment, during use, water is circulated into the heat exchange tube 2 installed inside the mounting shell 1, and steam generated during industrial waste liquid treatment is introduced into the mounting shell 1, allowing the circulating water and steam in the heat exchange tube 2 to exchange heat, thereby recovering the heat of industrial waste liquid evaporation. When impurities adhere to the surface of the heat exchange tube 2 after prolonged use, affecting the heat exchange effect, the connecting pipe 5 is connected to the corresponding pump source pipe. Pressurized cleaning water is then sprayed onto the surface of the heat exchange tube 2 through the connecting pipe 5 and the hose 4, and through the cleaning nozzle on the cleaning pipe 3, thereby rinsing the heat exchange tube 2 and maintaining a good overall heat exchange effect. During cleaning, the angle of the cleaning pipe 3 on the heat exchange tube 2 is adjusted by the adjustment mechanism to make the cleaning more comprehensive and effective, further improving the cleaning effect and ensuring the heat exchange performance of the heat exchange tube 2. This device can recover the heat of industrial waste liquid evaporation and facilitate the cleaning of the heat exchange tube 2, maintaining a good overall heat exchange effect. The mounting shell 1 is equipped with a discharge pipe, which is used to discharge the wastewater used for cleaning the heat exchange tube 2 and to discharge steam condensate.

[0027] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a first servo motor 6 fixedly mounted on the mounting shell 1; a plurality of synchronous pulleys 7 respectively fixedly sleeved on the plurality of cleaning pipes 3 and the output shaft of the first servo motor 6, and a plurality of synchronous belts 8 sleeved on the plurality of synchronous pulleys 7.

[0028] In this embodiment, when cleaning the heat exchange tube 2, the controller starts the output shaft of the first servo motor 6 to rotate in a certain forward and reverse direction, driving the synchronous wheel 7 fixedly sleeved on its output shaft to rotate. Since multiple cleaning tubes 3 are also fixedly sleeved with synchronous wheels 7, and multiple synchronous belts 8 are sleeved on multiple synchronous wheels 7, the multiple cleaning tubes 3 are rotated back and forth at a certain angle through the transmission action of the synchronous belts 8, thereby increasing the cleaning area of ​​the heat exchange tube 2, making the cleaning more comprehensive and effective, and further improving the cleaning effect.

[0029] In a further preferred embodiment of the present invention, the mounting shell 1 is provided with two mounting pipes 9, one of which is used to introduce steam generated during the processing of industrial waste liquid into the mounting shell 1, and the other mounting pipe 9 is used to discharge the steam after heat exchange from the mounting shell 1. The mounting pipe 9 is provided with an adjustment mechanism for adjusting the air flow rate of the mounting pipe 9.

[0030] In this embodiment, during use, one mounting pipe 9 is connected to the steam pipe generated by the industrial waste liquid processing. The steam enters the mounting shell 1 through the mounting pipe 9. The other mounting pipe 9 is used to discharge the steam after heat exchange from the mounting shell 1. The steam ventilation speed can be adjusted according to the actual situation through the adjustment mechanism. For example, when the heat exchange effect is good, the ventilation speed can be appropriately reduced to reduce energy waste; when the heat exchange effect decreases, the ventilation speed can be appropriately increased to ensure heat recovery efficiency, thereby improving the heat recovery efficiency and stability of the entire industrial waste liquid evaporation heat recovery device.

[0031] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a second servo motor 10 fixedly installed on the outer wall of one side of the mounting tube 9; a mounting shaft 11 rotatably installed on the mounting tube 9, one end of the mounting shaft 11 being fixedly connected to the output shaft of the second servo motor 10; and a stop block 12 fixedly sleeved on the mounting shaft 11, the stop block 12 being adapted to the inner wall of the mounting tube 9.

[0032] In this embodiment, when it is necessary to adjust the ventilation speed of the installation pipe 9, the second servo motor 10 is started. The output shaft of the second servo motor 10 rotates, which drives the stop block 12 on the installation shaft 11 to rotate inside the installation pipe 9, changing the size of the opening between the stop block 12 and the inner wall of the installation pipe 9, thereby realizing the adjustment of the ventilation speed of the installation pipe 9. The ventilation speed of steam can be precisely adjusted according to the actual situation.

[0035] In a further preferred embodiment of the present invention, a first filter box 15 is provided on the water inlet pipe 14, and a filter screen 16 for filtering large particulate impurities in the water is provided in the first filter box 15. A second filter box 17 is provided on the water inlet pipe 14, and activated carbon and anthracite are provided in the second filter box 17.

[0036] In this embodiment, when water flows into the heat exchange tube 2, the water first passes through the first filter box 15 when it enters the inlet pipe 14. The filter screen 16 in the first filter box 15 filters out large particulate impurities in the water. The water after passing through the first filter box 15 continues to flow and enters the second filter box 17. The activated carbon and anthracite in the second filter box 17 adsorb and filter out small particulate impurities, odors, pigments, etc. in the water, further purifying the water quality. On the one hand, this improves the safety of water use, and on the other hand, it reduces the residue of impurities in the heat exchange tube 2.

[0038] In this embodiment, when water is passed through the heat exchange tube 2, the soft material tube and the corresponding water source pipe are connected. The first filter box 15 can be sealed by the sealing cover 18, and the sealing gasket 19 can increase the seal between the sealing cover 18 and the first filter box 15 to prevent water leakage. The support block 20 is used to support and place the filter screen 16. When the sealing cover 18 and the first filter box 15 are sealed and connected, the abutment rod 21 can abut and fix the filter screen 16, thereby improving the stability of the filter screen 16 during use.

[0039] In a further preferred embodiment of the present invention, a hook 22 is fixedly installed on the sealing cover 18, and a buckle 23 is fixedly installed on the outer wall of the first filter box 15, wherein the buckle 23 and the hook 22 are adapted to be connected.

[0040] In this embodiment, the sealing cover 18 and the first filter box 15 can be connected and fixed by the cooperation of the buckle 23 and the hook 22, while facilitating the disassembly of the first filter box 15 and the cleaning of the filter screen 16.

[0041] In summary, compared with related technologies, this device can recover the heat from the evaporation of industrial waste liquid and facilitates the cleaning of heat exchange tube 2, thus maintaining a better overall heat exchange effect.
