Beneficial Effects

[0014] 1. The waste heat recovery pipeline of the present invention is fixedly installed on three reinforcement plates, thereby recovering the waste heat of the desulfurization slurry and heating the indoor air when used in winter.

[0015] 2. In the present invention, eight sealing blocks A are fixedly installed at the bottom of eight lifting shafts, and the outer walls of the eight sealing blocks A are in contact with eight hollow tubes.

Moreover, eight reset springs are mounted on the outside of the eight lifting shafts, and the eight reset springs are located between the eight crosses and the eight sealing blocks A. Therefore, when the sealing block B moves upward, the eight hollow conical covers are slowly reset under the action of the eight reset springs. Since the magnet B is fixedly mounted inside the waste heat recovery pipeline, and the magnet B is located directly below the magnet A, when the eight hollow conical covers are slowly reset, the magnet B and the magnet A are instantaneously in contact, thereby sealing the lower end of the waste heat recovery pipeline, thereby making the eight sealing blocks A continue to move upward under the action of the desulfurization slurry pressure, thereby realizing the up and down reciprocating movement of the eight hollow conical covers, thereby improving the utilization effect of waste heat.
