The utility model relates to
turbine fan technical field, and disclose
paper mill is with
turbine fan hot air recycling device, including device shell, still include first air inlet and filter mechanism, the bottom fixed connection of device shell has the support base plate of support device whole usefulness, the outside of device shell is provided with the filter mechanism for filtering high temperature
waste gas, the first air inlet of making cold gas enter is fixedly connected on device shell, the heat exchange
pipe body for heat exchange is fixedly connected on device shell. When carrying out heat exchange work, detect temperature value through temperature sensor body, and through controller body control telescopic link body adjust the distance between page board, to this control
cold air flow rate, can compare according to the actual temperature of current and the target temperature of setting, accurately judge whether the air flow needs to be adjusted, when needing, through the flow space of control
cold air to this reduce the flow rate of
cold air, make the heat exchange effect more stable, help to save cold quantity.
