[0031] The waste heat recovery device 6 includes an inner smoke outlet pipe 61, an outer cover 62, a heat sink 63, a hot air outlet 64, a partition 65, an air inlet 66, a connecting flange 67, a hot air connecting pipe 68, a second hot air cover 69, and a second hot air hood 69. Hot air distributor 70. The inner smoke outlet pipe 61 is a section of low pressure fluid conveying welded pipe. Its lowermost end is connected with a connecting flange 67. Its outer circle is sleeved in the outer cover 62 from top to bottom. The outer circle of the smoke outlet pipe 61 and the outer cover The annular columnar space between 62 is divided into a cold room and a hot room by two axially symmetrical partitions 65. The cold room is located on the outside, and a cold air inlet 66 is provided at the lower end, and the hot room is located on the inside and is provided at the lower end. Hot air outlet 64. There are 12 radiating fins evenly distributed longitudinally in both the cold room and the hot room; the cold room and the hot room pass through at the uppermost end; one end of the hot air connecting pipe 68 is connected to the hot air outlet 64, and the other end is connected to the second hot air hood 69 and the hot air distributor 70.
