Then the deodorized oil enters the deacidification tower 16 through the input end of the deacidification tower 16 for deacidification treatment. In the deodorization process, the deacidification tower 16 needs to deliver the vacuum in the Roots mechanical vacuum unit 3 and the steam output from the sixth output end of the steam generator 1 to the deacidification tower 16 for vacuum heating and deacidification treatment of the deodorized oil inside the deacidification tower 16, to obtain deacidified oil. The deacidified oil is delivered to the deacidification heat exchanger 17 through the input A end of the deacidification heat exchanger 17 for heat exchange treatment. In the heat exchange process, the deacidification heat exchanger 17 needs to deliver the heat exchange oil in the heat exchange oil tank 5 to the deacidification heat exchanger 17 for heat exchange treatment of the deacidified oil inside the deacidification heat exchanger 17. The heat-exchanged deacidified oil enters the cooling tower 18 through the input A end of the cooling tower 18 for cooling treatment. In the cooling process, the cooling tower 18 needs to deliver the cooling water in the cooling water storage tank 28 to the cooling tower 18 for cooling treatment of the deacidified oil inside the cooling tower 18. The cooled deacidified oil enters the bag filter 19 through the input end of the bag filter 19 for filtration to obtain finished oil, which is then sent to the finished oil storage 20 for storage.
