Steam-curing air heater for construction waste building blocks

A gas pipe and a water pipe are connected to the front portion and the rear portion of the steam-curing hot-air blower respectively. Fuel gas in the fuel gas pipe sequentially flows through the fuel gas burner and the burning bin. After being mixed with air entering from the air inlet in the combustion bin, the gas is ignited by the gas burner to form hot mixed gas; hot mixed gas is blown into a room by an air blower, so that the indoor temperature is increased, and indoor green bricks are cured; water in the water pipe cools the bearing and then enters the air outlet pipe through a pipeline B, so that the humidity of hot mixed gas flowing through the air outlet pipe is increased; the three-way valve on the pipeline B can control whether air enters the air outlet pipe or not; in this way, the indoor temperature can be controlled, the indoor humidity can also be controlled, and the maintenance efficiency and the finished product quality of the construction waste building blocks are guaranteed. 一种建筑垃圾砌块用蒸养热风机，前
