[0040] Reference Figure 1 、 Figure 3 and Figure 4 The filter element includes a connecting frame 20 that is symmetrically slidably connected to the inside of the filter box 16. An activated carbon filter plate 21 is arranged inside the connecting frame 20. Two sliders 22 are symmetrically fixedly connected at both ends of the connecting frame 20. Two slide grooves 23 are symmetrically opened on both sides of the interior of the filter box 16. The two sliders 22 are slidably connected in the slide grooves 23.

The rotation of the two cams 26 can continuously impact the connecting frames 20 on both sides, so that the two connecting frames 20 drive the slider 22 to slide back and forth in the slide groove 23. In the sliding process, the springs 27 at both ends will be squeezed to continuously rebound and contract.

[0042] The implementation principle of the waste heat utilization system of a thermoelectric steam turbine in this embodiment is as follows: when in use, the air inlet pipe 2 is first connected to the steam exhaust end of the thermoelectric steam turbine to allow high-temperature steam to enter the interior of the box body 1, and then cold water is poured into the water tank 4 through the water inlet pipe 5, so that the cold water enters the interior of the metal heating pipe 7. When the high-temperature steam continues to enter the interior of the box body 1, it will contact the metal heating pipe 7. At this time, the metal heating pipe 7 can absorb the heat in the high-temperature steam, thereby heating the cold water inside the metal heating pipe 7. Secondly, while the steam continues to heat the water source inside the metal heating pipe 7, the circulation pump 8 can be started to operate to continuously circulate the water source inside the water tank 4, pump the heated water inside the metal heating pipe 7 into the water tank 4, and then re-guide the cold water to the metal heating pipe 7, and continue to heat the cold water with the high-temperature steam, thereby effectively improving the recovery and utilization of the waste heat in the high-temperature steam, reducing the direct discharge of steam, thereby reducing the emission of gas and other pollutants, alleviating environmental pressure, complying with the national environmental protection policy, and achieving energy saving. and reuse. After the metal heating tube 7 has been used for a long time, some dirt remaining in the high-temperature steam will gradually be generated and attached to its surface.

In the process of reciprocating movement, the cleaning brush 13 inside the through hole can continuously scrape and clean the dirt on the outer wall of the metal heating tube 7, thereby effectively improving the cleanliness of the metal heating tube 7, so that the metal heating tube 7 can continue to maintain an efficient heat exchange effect and better utilize the high-temperature waste heat generated by the steam turbine. Then, the dirt falls on the inclined platform 28 according to the influence of gravity, and is uniformly collected in the collection box 29 through the inclined surface of the inclined platform 28, waiting for subsequent cleaning by the staff, thereby effectively improving the cleanliness of the metal heating tube 7, so that the metal heating tube 7 can continue to maintain an efficient heat exchange effect and better utilize the high-temperature waste heat generated by the steam turbine.

[0043] In the process of waste heat utilization, in order to reduce the impact of impurities in the steam on the metal heating pipe 7 and the situation that some heat cannot be fully utilized, the second pump 18 can be started to operate to guide the steam inside the box 1 through the guide pipe 1 15 and the guide pipe 2 19 to re-enter the interior of the box 1 for steam circulation, and in the process of steam circulation, the activated carbon filter plate 21 set in the filter box 16 can effectively reduce the impurities remaining in the steam, thereby reducing the impact on the metal heating pipe 7 during the waste heat utilization process, and in the process of filtering, the second motor 25 can be started to drive the two cams 26 to rotate, and the rotation of the two cams 26 can continuously impact the connecting frames 20 on both sides, so that the two The connecting frame 20 drives the slider 22 to slide back and forth inside the slide groove 23. During the sliding process, the springs 27 at both ends will be squeezed to continuously rebound and shrink. The rebound and contraction of the springs 27 will cause the connecting frame 20 to drive the activated carbon filter plate 21 to continuously shake during the filtration process, so that the particles inside the activated carbon filter plate 21 can be better dispersed, thereby improving the filtration efficiency, and can remove some coverings adhering to the surface of the activated carbon filter plate 21, restore the adsorption performance of the activated carbon filter plate 21, restore the permeability of the filter layer, and prevent the filter layer from being blocked.
