Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in figure 1, a condensation buffer type propionitrile distillation tower comprises a tower body 1, a kettle body 2 arranged at the bottom of the tower body 1, a condenser 3 and a buffer tank 4. Wherein the top of the tower body 1 is provided with a tower body discharge hole 11, the top of the condenser 3 is provided with a condenser feed inlet 31, and the bottom is provided with a condenser discharge hole 32; the tower body discharge port 11 is connected with the condenser feed port 31 through a pipeline, and the side wall of the condenser 3 is provided with a cooling coil 33. The top of buffer tank 4 is provided with buffer tank feed inlet 41, and the bottom is provided with buffer tank discharge gate 42, and condenser discharge gate 32 pipeline divides into two branch road pipelines, is first branch road 71 and second branch road 72 respectively, connects tower body feed back 12 and buffer tank feed inlet 41 respectively. The buffer tank 4 is further provided with a vacuum port 43 connectable to a vacuum pump (not shown) via a vacuum line 75.
The buffer tank outlet 42 is connected to the inlet of the discharge pump 5 via a pipe (not shown). The outlet (not shown) of the discharge pump 5 is connected with two branches, a third branch 73 and a fourth branch 74, wherein the third branch 73 is connected with the buffer tank feed back port 44, and the fourth branch 74 can be connected with a downstream use unit.
The bottom of the kettle body 2 is also provided with a sewage discharge outlet 21, and a pipeline and a valve are arranged for sewage removal treatment operation. A heating coil 6 is arranged in the kettle body 2, and high-temperature steam is injected through a steam pipeline 61. The bottom of the kettle body 2 is provided with a condensed water outlet 22 which is connected with a pipeline and a valve for discharging the steam condensate to a clear water ditch.
The principle is briefly described as follows: the propionitrile gas enters a condenser through a discharge hole at the top of the tower body, is condensed into liquid, flows into a buffer tank and is discharged to a downstream use unit through a discharge pump. This novel water-cooled condenser cooling rate that adopts is fast, and the buffer tank can play the effect of storage regulation and control propionitrile liquid flow. Meanwhile, the condensing unit and the buffer tank unit are provided with backflow branches, so that the flow of each link is kept more stable.
