[0026] Reference Figure 1 A novel reactor of this embodiment includes a reactor body 1, a sampling assembly 2 and a receiving assembly 3 arranged on one side of the reactor body 1. When the reactants in the reactor need to be characterized and analyzed, the reactant solution is taken out through the sampling assembly 2, and the pressure of the reactant solution in the sampling assembly 2 is reduced, and then the reactant solution is received and processed by the receiving assembly 3 and transferred to the characterization analysis.

[0027] Reference Figure 2 The sampling assembly 2 includes a first sampling tube 21 disposed on one side of the kettle body 1, a second sampling tube 22 connected to the receiving assembly 3, and a pressure drop display tube 23 integrally connected between the first sampling tube 21 and the second sampling tube 22. In the embodiment of the present application, the receiving assembly 3 is a receiving pipe connected to the second sampling tube 22, wherein the receiving pipe and the second sampling tube 22 are detachably connected, and after the reactant solution is collected in the receiving pipe, it can be transferred for characterization.

By controlling the pressure in the pressure reduction chamber 231 by the pressure reduction valve 232 and displaying the pressure in the pressure reduction chamber 231 in real time through the display screen 233, the occurrence of the reactant spraying from the sampling assembly 2 is reduced.

[0029] Furthermore, a pressure-reducing hole 234 is provided on the pressure-reducing display tube 23 to connect the pressure-reducing chamber 231 with the outside, and a baffle 235 is provided on the pressure-reducing valve 232 to open or close the pressure-reducing hole 234. The pressure-reducing hole 234 is closed or opened by controlling the pressure-reducing valve 232, thereby controlling the pressure in the pressure-reducing chamber 231, and the pressure is displayed in real time on the display screen 233 to improve the safety of operation.

[0030] In addition, the pressure-reducing display tube 23 is provided with a shunt pipe 236 communicating with the pressure-reducing hole 234. At the same time, the shunt pipe 236 is provided with a connection port for connecting to an external pipeline, so that when the pressure-reducing valve 232 is opened, in order to prevent the liquid in the pressure-reducing chamber 231 from spraying out from the pressure-reducing hole 234, the liquid sprayed out from the pressure-reducing hole 234 will enter the external pipeline through the connection port, further improving the safety of the operation of the pressure-reducing display tube 23.

[0031] Reference Figure 3 and Figure 4 The first sampling tube 21 is integrally provided with a first positioning plate 211 in the direction of the step-down display tube 23, and a plurality of first connection holes 212 are provided on the first positioning plate 211; the step-down display tube 23 is integrally provided with a second positioning plate 241 in the direction of the first sampling tube 21, which is tightly abutted against the first positioning plate 211, and a second connection hole 242 corresponding to and communicating with the first connection hole 212 is provided on the second positioning plate 241. The step-down display tube 23 is provided with a first positioning rod 243, and the first positioning rod 243 is correspondingly penetrated through each group of the first connection holes 212 and the second connection holes 242.

[0032] Similarly, the second sampling tube 22 is integrally provided with a third positioning plate 221 in the direction of the step-down display tube 23, and at least one third connection hole 222 is provided on the third positioning plate 221; the step-down display tube 23 is integrally provided with a fourth positioning plate 244 in the direction of the second sampling tube 22, which is tightly against the third positioning plate 221, and a fourth connection hole 245 corresponding to and communicating with the third connection hole 222 is provided on the third positioning plate 221. Similarly, the step-down display tube 23 is provided with a second positioning rod 246, and the second positioning rod 246 is correspondingly penetrated through each group of third connection holes 222 and fourth connection holes 245. In the embodiment of the present application, the first positioning rod 243 and the second positioning rod 246 are both bolts, and the connection between the first sampling tube 21 and the step-down display tube 23, and the tight connection between the second sampling tube 22 and the step-down display tube 23 are achieved by the bolts.

[0033] Furthermore, the first sampling tube 21 is provided with a first sealing ring 213 at the connection of the pipeline, and the pressure reduction display tube 23 is provided with a first sealing groove 25 for the first sealing ring 213 to abut and receive. During the installation of the first fixed sampling tube, the first sealing ring 213 abuts against the groove wall in the first sealing groove 25, thereby improving the sealing of the installation of the first sampling tube 21. Similarly, the second sampling tube 22 is provided with a second sealing ring (not shown in the figure) at the connection of the pipeline, and the pressure reduction display tube 23 is provided with a second sealing groove (not shown in the figure) for the second sealing ring to abut and receive.

When it is necessary to sample the reactants in the reactor, first, close the second valve 223, open the first valve 214 and control the flow rate of the reactant solution flowing through the pressure reduction display tube 23, and then close the first valve 214; secondly, connect an external pipeline to the connection port of the shunt tube 236, and slowly open the pressure reduction valve 232, and observe that the pressure in the pressure reduction chamber 231 in the display screen 233 is the same as the external atmospheric pressure; finally, open the second valve 223, the reactant solution flows into the second sampling tube 22, and the reactant solution in the second sampling tube 22 is characterized to reduce the occurrence of reactants spraying from the sampling component 2.
