[0019] See also Figures 1 to 3 Preferably, the heat conducting pipe of the present invention comprises a left heat conducting pipe 11 and a right heat conducting pipe 12, and the temperature sensing component is arranged between the left heat conducting pipe 11 and the right heat conducting pipe 12, and can automatically close or open the right heat conducting pipe 12 according to the steam temperature.

[0020] See also Figures 1 to 3 In addition, the input end of the left heat conducting pipe 11 of the utility model is arranged at the upper end of the tower body 1, the output end of the right heat conducting pipe 12 is connected to the recovery box 2, and the output end of the reflux pipe 21 is connected to the recovery box 2, which is convenient for recovering steam water and reducing the water replenishment amount of the circulating water system.

[0021] See also Figures 1 to 3 Furthermore, the top of the vertical rod 34 of the utility model is fixedly connected with an inner tube 33, and the inner tube 33 is arranged in the sleeve 31. An elastic member 342 is provided between the vertical rod 34 and the temperature sensing box 3 to facilitate the resetting of the vertical rod 34.

[0022] See also Figures 1 to 3 Better yet, the sleeve 31 of the utility model is fixedly connected to the temperature sensing box 3, and a temperature sensing material 32 is provided between the sleeve 31 and the inner tube 33. The temperature sensing material 32 can expand or contract as the temperature rises or falls; and a sealing ring is provided on the outer side of the inner tube 33 to ensure that the temperature sensing material 32 does not overflow.

[0023] Working principle: The steam generated by the tower body 1 flows out from the left heat conducting pipe 11, flows into the recovery box 2 through the right heat conducting pipe 12 or the reflux pipe 21, and the steam is condensed and recovered;

[0024] When the ambient temperature is high, the heat loss of steam in the left heat conducting pipe 11 is small, which can drive the temperature sensing material 32 to expand, drive the inner pipe 33 to move downward against the vertical rod 34, and the vertical rod 34 drives the upper baffle 341 to move downward, and the temperature sensing box 3 is provided with a moving space for the upper baffle 341; when the vertical rod 34 moves downward, the cross bar 41 is pushed to move by the connecting rod 5, driving the lower baffle 411 to close the return pipe 21, and the steam flows from the left heat conducting pipe 11 to the right heat conducting pipe 12 and then to the recovery box 2, and the heat energy in the steam is recycled by the heat conducting pipe;

[0025] When the ambient temperature is low, the heat loss of steam in the left heat-conducting pipe 11 is large, and the temperature-sensitive material 32 cannot drive the inner tube 33 to move downward. At this time, the elastic member 342 drives the upper baffle 341 to be located at the top, and closes the right heat-conducting pipe 12. The vertical rod 34 drives the lower baffle 411 to be located on the left side through the horizontal rod 41, and the return pipe 21 is set in an open state. At this time, the steam flows from the left heat-conducting pipe 11 into the return pipe 21 and then into the recovery box 2, avoiding the condensation of steam in the right heat-conducting pipe 12 and making it inconvenient to recover, thereby improving the recovery efficiency of steam water.

[0026] In summary, the utility model provides a cooling tower waste heat recovery device, including: a heat conducting pipe, a temperature sensing component arranged in the middle of the heat conducting pipe, the temperature sensing component including a temperature sensing box, an upper baffle arranged in the temperature sensing box, a vertical rod vertically fixed to the upper baffle, through which the connection channel between the left heat conducting pipe and the right heat conducting pipe can be closed or opened; a return pipe arranged on the front side of the input end of the temperature sensing component, a valve box arranged on the return pipe, a lower baffle arranged in the valve box, through which the return pipe can be closed or opened, a cross bar vertically fixed to the lower baffle, a connecting rod hinged between the cross bar and the vertical rod; the utility model can automatically open or close the right heat conducting pipe and the return pipe according to the steam temperature of the cooling tower through the temperature sensing component, can select two circulation pipelines of the right heat conducting pipe and the return pipe according to the ambient temperature, can improve the waste heat utilization rate and the recovery efficiency of evaporated water.
