[0031] It should be noted that in some practical situations, in order to achieve photoelectrocatalytic reactions, additional light sources are required. Please refer to Figure 1 The independent light source 111 is the light source for photoelectrocatalytic reaction. When photoelectrocatalysis is carried out, the configured reaction liquid is passed through the sampling port 109 at a certain flow rate through an external injection pump, and then the reaction liquid enters the gap between the cathode tube 103 and the anode tube 104, that is, the reaction channel, and the electrocatalytic reaction of the reaction liquid is completed by the cooperation of the cathode tube 103 and the anode tube 104. At the same time, the external independent light source 111 is combined to realize the photoelectrocatalytic reaction. It should be noted that the fixed shell in this embodiment also has a sampling port 110, so that the reaction liquid can flow, thereby greatly improving the photoelectrocatalytic efficiency of the reaction liquid. In some preferred embodiments, the circulation of the reaction liquid can be completed by the injection pump and the pipeline to ensure the complete photoelectrocatalysis of the reaction liquid.

[0032] In some preferred embodiments, the channel width of the gap formed between the cathode tube 103 and the anode tube 104 may be 2 mm.

[0033] In addition, in order to realize the electrocatalytic reaction, in the present embodiment, the fixed shell includes a fixed sleeve 105, an upper cover 101 and a lower cover 106 arranged at both ends of the sleeve 105; one of the upper cover 101 and the lower cover 106 is arranged at the sample outlet 110 and the sample inlet 109, and the other is provided with a cathode terminal 108 and an anode terminal 107; the anode terminal 107 is used to connect to the end of the anode tube 104, and the cathode terminal 108 is used to connect to the end of the cathode tube 103.

[0034] Furthermore, the upper cover 101 is detachably connected to one end of the fixed sleeve 105, the lower cover 106 is detachably connected to the other end of the fixed sleeve 105, and the injection port 109 and the injection port 109 are arranged on the upper cover 101, the cathode terminal 108 and the anode terminal 107 are arranged on the lower cover 106, and the seal 102, the anode tube 104 and the cathode tube 103 can all be detachably connected in the fixed sleeve 105.

[0035] To ensure the reliability of sealing and installation of the anode tube 104 and the cathode tube 103, in some other preferred embodiments, the anode slot 1021 includes a first anode gap portion and a second anode gap portion, and the size of the first anode gap portion extends from large to small toward the direction of the second anode gap portion, wherein the gap size of the end of the first anode gap portion close to the anode tube 104 is larger than the cross-sectional size of the anode tube 104, and the gap size of the second anode gap portion corresponds to the cross-sectional size of the anode tube 104;

[0036] The cathode slot 1022 includes a first cathode gap portion and a second cathode gap portion, and the size of the first cathode gap portion extends from large to small in the direction of the second cathode gap portion, wherein the end gap size of the first cathode gap portion close to the cathode tube 103 is larger than the cross-sectional size of the cathode tube 103, and the gap size of the second cathode gap portion corresponds to the cross-sectional size of the cathode tube 103.

[0037] Specifically, in the present embodiment, there are two seals 102, which are respectively located at the two ends of the anode tube 104 and the cathode tube 103, that is, the anode tube 104 can be clamped through the anode clamping groove 1021 in one seal 102, and the size of the first anode gap part in the anode clamping groove 1021 extends from large to small in the direction of the second anode gap part. The size difference makes it easy for the anode tube 104 to enter. At the same time, the second anode gap part corresponds to the cross-sectional size of the anode tube 104, so that the anode tube 104 is clamped by the second anode gap part. Similarly, the cathode tube 103 is clamped with the cathode clamping groove 1022 in the same manner as the anode tube 104. Through this arrangement, the safety and reliability of the installation are improved under the premise of ensuring the sealing performance.

[0039] In the sleeve-type photoelectrocatalytic reactor provided by the utility model, a gap portion for the reaction liquid to flow is formed between the anode tube 104 and the cathode tube 103 due to the size difference between the anode tube 104 and the cathode tube 103, and the gap portion is respectively connected to the injection port 109 and the outlet port 110, so that the reaction liquid can flow through a very small flow gap, thereby avoiding the problem of incomplete photochemical reaction due to a large liquid volume.
