[0029] It should be noted that by using the filter plate 24 to filter the hot air in the waste heat recovery component 2 and using the hot air to heat the water, clean heat recovery of the waste heat of the cold storage equipment body 1 can be achieved, energy utilization efficiency can be improved, and energy costs can be saved. At the same time, the recovery and utilization of hot air is cleaner and the utilization rate is more efficient.

[0030] Furthermore, in actual use, by means of the pressure limit of the filter screen 24 between the set top plate 241, the compression spring 242 and the connecting plate 243, when the filter screen 24 needs to be cleaned or replaced, only the connecting plate 243 needs to be loosened to conveniently remove the filter screen 24 from the waste heat recovery box 21 for cleaning or replacement, thus saving time and labor costs; by quickly disassembling and assembling the filter screen 24, the filter screen 24 can be cleaned or replaced in time to maintain its good filtering performance, and the cleaning and replacement of the filter screen 24 can effectively remove the particulate matter contained in the hot air, maintain the permeability and filtering efficiency of the filter screen 24, and ensure that the hot air in the waste heat recovery box 21 can fully pass through the filter screen 24, thereby improving the heat recovery effect.
