[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 A waste heat recovery device for treating hazardous waste mixtures includes a heat exchange box 1. A flue pipe 2 is fixedly connected to the upper left side of the heat exchange box 1. A pressurization mechanism 3 is installed inside the flue pipe 2. A multi-tube heat exchanger 4 is fixedly connected inside the heat exchange box 1. A flue pipe 5 is fixedly connected to the lower right side of the heat exchange box 1. A filter box 6 is fixedly connected to the end of the flue pipe 5 away from the heat exchange box 1. A box cover 7 is threadedly connected to the upper end of the filter box 6. An exhaust pipe 8 is fixedly connected inside the box cover 7. A filter barrel 9 is installed on the inner bottom of the filter box 6 through a bearing. A fixing frame 10 is fixedly connected to the inner top of the box cover 7. A fan blade 11 is installed on the inside of the fixing frame 10 through a bearing. A connecting strip 12 is fixedly connected to the lower end of the fan blade 11. A connecting ring 14 is fixedly connected to the upper part of the inner wall of the filter barrel 9.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5A connecting post 13 is fixedly connected to the lower end of the connecting strip 12. The connecting post 13 is slidably connected to the connecting ring 14. The connecting post 13 can drive the filter barrel 9 to rotate through the connecting ring 14. The connecting strip 12 is slidably connected to the connecting ring 14 and the filter barrel 9. The fan blade 11 can drive the connecting strip 12 to rotate. A sealing ring 15 is installed on the upper part of the inner wall of the filter box 6 through a bearing. The sealing ring 15 is slidably connected to the filter barrel 9 and can seal the connection between the filter barrel 9 and the filter box 6.

[0024] Please see Figure 2 , Figure 4 The pressurization mechanism 3 includes a pressurization hood 31. The pressurization hood 31 is fixedly connected to the lower part of the inner wall of the exhaust pipe 2. A fixing strip 32 is fixedly connected to the upper part of the inner wall of the pressurization hood 31. A connecting pin 33 is slidably connected inside the fixing strip 32. A sealing plate 34 is fixedly connected to the upper end of the connecting pin 33. A spring 35 is provided on the outside of the connecting pin 33. The connecting pin 33 can drive the sealing plate 34 to move. The sealing plate 34 contacts the pressurization hood 31 and contacts the fixing strip 32. The sealing plate 34 can seal the pressurization hood 31. One end of the spring 35 is fixedly connected to the connecting pin 33, and the other end of the spring 35 is fixedly connected to the fixing strip 32. The spring 35 can drive the connecting pin 33 to automatically reset through its elastic force.

[0025] The specific implementation process of this utility model is as follows: In use, the flue gas enters the interior of the filter box 6 through the exhaust pipe 8. After being filtered by the filter barrel 9 inside the filter box 6, it flows into the interior of the heat exchange box 1. When the exhaust gas comes into contact with the multi-tube heat exchanger 4 inside the heat exchange box 1, heat exchange occurs. At the same time, as the exhaust gas enters the heat exchange box 1, the internal pressure increases. When the pressure pushes the sealing plate 34 to a force greater than the elastic force of the spring 35, the sealing plate 34 can be moved upward, which can discharge the gas after heat exchange inside the heat exchange box 1. During the discharge process, when the pressure is less than the elastic force of the spring 35, the spring 35 automatically resets, which can prevent the discharge of the flue gas and increase the internal pressure of the heat exchange box 1 again, thereby increasing the residence time of the flue gas.

[0026] During the flue gas filtration process, the flue gas drives the fan blades 11 to rotate. The fan blades 11 drive the filter barrel 9 to rotate through the connecting strips 12 and connecting columns 13. The centrifugal force generated by the rotation of the filter barrel 9 and the blowing force generated by the flue gas flow can disturb the dust inside the filter barrel 9, thereby preventing the filter barrel 9 from clogging.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
