Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1 to 3, the continuous stripping apparatus includes a stripping column 1, a feed liquid tank 2, a feed liquid pump 3, a heater 4, a condenser 5 and a product tank 6.
The feed liquid tank 2 is connected between the bottom of the stripping tower 1 and the inlet of the feed liquid pump 3, the outlet pipe of the feed liquid pump 3 is communicated to the feed liquid spraying system 7, the heater 4 is arranged between the feed liquid pump 3 and the feed liquid spraying system 7, the inlet of the condenser 5 is communicated with the gas phase pipeline at the top of the stripping tower 1, and the finished product tank 6 is communicated with the outlet pipe of the condenser 5. The feed tank 2 is provided with a feed pipe and a discharge pipe to realize material balance in the stripping process through feeding and discharging. The feed liquid is conveyed into the heater 4 by the feed liquid pump 3 to be heated and then is conveyed into the stripping tower by the feed liquid spraying system 7, after the stripping is finished in the stripping tower 1, the target product enters the condenser 5 through a gas phase pipeline at the top of the stripping tower 1 and enters the finished product tank 6 after being condensed by the condenser 5.
The steam coil 8 is arranged at the bottom of the stripping tower 1, saturated steam is provided for the steam coil 8 through a steam pipeline, feed liquid is sprayed by the feed liquid spraying system 7 and is in countercurrent contact with the steam, the contact area of the atomized feed liquid and the steam is large, and the stripping efficiency is high. The spray head of the feed liquid spraying system 7 is a spiral spray head, and the feed liquid sprayed by the spiral spray head has a certain rotating track, so that the spiral spray head can generate a rotating action on steam, and the contact effect of the steam and the feed liquid is further enhanced. Through set up heater 4 on the 3 outlet pipes of feed liquid pump, adopt feed liquid and steam to strip against the current in the strip tower 1, so, can avoid feed liquid and steam difference in temperature too big, the gas temperature in the strip tower 1 is better controlled simultaneously.
