Cold bed waste heat recovery device

The utility model relates to a hot rolling steel pipe cold bed waste heat recovery device, it includes steel calandria, water knockout drum, water collector, total inlet tube, total outlet pipe, electrical control valve, temperature sensor. Device internal recycling aquatic is retrieved with the heat that hot rolling steel pipe cold bed gived off through the heat exchange to the device more than utilizing to through the circulating water with heat transfer to waste heat utilization equipment, thereby realize the surplus pick up the heat of cold bed, it is extravagant to reduce the energy. And this device can realize through the control leaving water temperature that the circulating water directly is used for the heating system that different hot water temperature such as radiator heating or air conditioner heating required. 本实用新型是种热轧钢管冷床余热回收装置，其包括钢排管、分水器、集水器、总进水管、总出水管、电动调节阀、温度传感器。利用以上装置，将热轧钢管冷床散发的热量通过热交换回收到装置内部循环水中，并通过循环水将热量输送至余热利用装置，从而实现冷床余热的回收利用，减少能源浪费。并且本装置通过控制出水温度，可以实现循环水直接用于散热器采暖或者空调采暖等不同热水温度要求的采暖系统。
