Fig. 3 shows the structure of reactor communication means 200 of the present invention, as shown in figure 3, the air inlet pipe of long straight pipe shape
220 run through the first connector 211 and the 3rd connector 213 and extend into inside pressure-resistant bottle 100；The effect of air inlet pipe 220
It is that guiding purgative gas enters pressure-resistant bottle 100, but has single without the effect for discharging any gas, i.e. air inlet pipe 220
To air inlet act on.Due to the reactor relate separately to purge reactor, filling reaction gas, urea synthesizing in use it is anti-
Answer, four basic steps of scavenging, the structure of first association reaction kettle is explained respectively.
When purging reactor, the first globe type of control valve 251 and the second globe type of control valve 252 are all in opening, air inlet
Pipe 220 connects with source of purge gas, and the 4th connector 214 connects with outlet pipe, and purgative gas now is helium；Helium is along entering
Tracheae 220 enters inside pressure-resistant bottle 100, and is mixed with the air in pressure-resistant bottle 100, and mixed gas flows through the first company successively
Interface 211, the 4th connector 214, and enter outlet pipe, through helium purge after a while, it is used for emptying before inflation
Residual air in reactor, and then close the first globe type of control valve 251 and the second globe type of control valve 252.
When filling reaction gas, the second globe type of control valve 252 is opened, the first globe type of control valve 251 is still within closed mode,
4th connector 214 connects with feed gas source, and unstripped gas can flow through the 4th connector 214, the first connector 211 successively, and then
Into pressure-resistant bottle 100, liquid is cooled under strong refrigeration, falls into the bottom of bottle of pressure-resistant bottle 100, the lasting stream of unstripped gas
Enter to complete the filling of unstripped gas, close the first globe type of control valve 251 and the second globe type of control valve 252 to carry out subsequent reactions.
During urea synthesis reaction, the first globe type of control valve 251 and the second globe type of control valve 252 all in closed mode, this
When whole reactor there is no a substance circulating with extraneous, inside reactor13CO、S、NH3Reaction generation carbon【13C】- urea and H2S。
During scavenging, urea synthesis reaction has been completed.Because other raw materials are excessively launched to cause13CO can fill
Divide reaction complete, so also remaining unreacted complete S, NH in reactor3With the H of reaction generation2S.First globe type of control valve
251 and second globe type of control valve 252 connected all in opening, air inlet pipe 220 with source of purge gas, the 4th connector 214 with
Outlet pipe connects, and purgative gas now is nitrogen；Nitrogen along air inlet pipe 220 enter pressure-resistant bottle 100 inside, and with it is pressure-resistant
Gas mixing in bottle 100, mixed gas flows through the first connector 211, the 4th connector 214 successively, and enters escape pipe
Road, purged through nitrogen after a while, be used for emptying residual exhaust gases in reactor before inflation, and then close the first spherical control
The globe type of control valve 252 of valve 251 and second processed.
