Abstract
The invention discloses a countercurrent multistage rotating heat pipe hot blast stove. The countercurrent multistage rotating heat pipe hot blast stove which is composed of a cold air inlet, a hot air outlet, a high-temperature smoke inlet, a smoke outlet, a transmission device, a riding wheel device, a heat holding cover and heat exchanging cylinders. The multistage heat exchanging cylinders are composed of at least one rotating heat exchanging cylinder and one or more static heat exchanging cylinders. A smoke channel enables the rotating heat exchanging cylinder and the static heat exchanging cylinders to be connected in series, so that a multistage heat exchanging system is formed. Cold air and hot smoke conduct heat exchange stage by stage, so that the number of the procedures of heat exchange is increased and the time of heat exchange is prolonged. The rotating hot air cylinder enables heated airflow to form turbulent flow when the heated airflow passes through heat pipes, so that the number of the procedures of heat exchange is further increased and the time of heat exchange is further prolonged. Therefore, heat exchange is more sufficient, the heat exchange efficiency is improved, heat loss is reduced, energy consumption is reduced, the structure is simple, cost is low, and popularization and application are convenient.
