Embodiment 1
[0022] refer to Figure 1-3 As shown, an ejector for interfacial polymerization reaction includes a solution tank 1, a partition 2, a circulation device 3 and a guide roller 4, and the partition 2 is fixedly installed in the solution tank 1 and divides the solution tank 1 into an upper tank 101 1, the upper and lower parts of the lower groove 102, the partition plate 2 is provided with a number of wing-like structures 201 connecting the upper groove 101 and the lower groove 102, and the front end of the partition plate 2 is provided with an opening 202 connecting the upper groove 101 and the lower groove 102; The rollers 4 are installed in a linear array on the top of the upper tank 101 of the solution tank 1, a passage for the membrane 7 to pass is formed between the guide roller 4 and the separator 2, the bottom of the lower tank 102 of the solution tank 1 is provided with a circulation inlet 103, and the upper part is provided with a Circulation outlet 104;
[0023] The wi...
Embodiment 2
[0029] As a preferred embodiment of the present invention, this embodiment adds a flanging mechanism on the basis of the first embodiment.
[0030] refer to figure 2 and Figure 4 As shown, in order to make the diaphragm 7 only have one side contacting the solution to participate in the interface reaction, a kind of jet device for the interface polymerization reaction includes the flange plate 5, the flange plate 5 is two inclined plates, and the flange plate 5 is fixedly installed on On the inner wall of the upper groove 101 below the joint of the guide roller 4 rotating shaft and the upper groove 101, and the flanging plate 5 is located above the dividing plate 2;
[0031] Under the common clamping and limiting of the guide roller 4 and the inclined flange plate 5, the diaphragm 7 forms a groove-like structure, so that only one side of the diaphragm 7 participates in the interface reaction to form a high polymer layer. After the reaction, the solution and flocculation The...
Embodiment 3
[0033] As a preferred embodiment of the present invention, this embodiment adds a circulating liquid outlet pipe 6 on the basis of the second embodiment.
[0034] refer to figure 1 and Figure 5 As shown, in order to increase the flow rate of the solution, a jet device for interfacial polymerization, the circulation outlet 104 in the lower tank 102 of the solution tank 1 is connected with a circulation outlet pipe 6 full of hole-shaped nozzles 601, and the circulation outlet Tube 6 is a T-shaped tube.
[0035] In order to intensify the flow velocity of the solution in the lower tank 102, the solution that the circulation pump 302 is allowed to beat enters the lower tank 102 of the solution tank 1 through the circulation outlet pipe 6 that is full of hole-shaped nozzles 601, thus increasing the flow velocity of the solution and making the upper The discharge speed of the reacted solution and flocculent impurities in the tank 101 is accelerated, and new solution is quickly rep...
