Passing nitrogen from liquid-underground exists and catches up with chlorine efficiency is not high, catches up with chlorine uneven problem, is unfavorable for production control. If chlorine and hydrogen chloride can cause corrosion, damage to pipeline and equipment when entering subsequent production equipment, produce potential safety hazard. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0027] like Figure 1-Figure 4 As shown, in one embodiment, a continuous chlorine removal device includes a chlorine removal kettle 1. A heating jacket is provided on the outside of the chlorine removal kettle 1. Hot water can be introduced into the heating jacket to heat the chlorine removal kettle 1 to separate chlorine and hydrogen chloride from the reaction liquid.

[0028] The chlorine removal kettle 1 is connected to the gas-liquid separator 2 through a pipeline, and the gas-liquid separator 2 is connected to the tail gas absorption unit 3 through a pipeline. Similarly, the chlorine removal kettle 1 is also connected to the tail gas absorption unit 3 through a pipeline. The tail gas absorption unit 3 is a primary acid absorption tower, which can absorb and treat the discharged tail gas.

[0029] Furthermore, the mixture of chlorinated liquid, chlorine and hydrogen chloride enters the gas-liquid separator 2 after being discharged from the continuous reactor. The gas-liquid separator 2 is connected to the tail gas absorption unit 3, and the tail gas absorption unit 3 is provided with a blower 6, which can evacuate the gas-liquid separator 2 and the chlorine-eliminating kettle 1 to form a slightly negative pressure environment. Therefore, after the mixture enters the gas-liquid separator 2, the mixture, which was originally under positive pressure, is transferred to the slightly negative pressure environment, and a large amount of chlorine and hydrogen chloride are separated from the liquid phase in the form of pressure release, and enter the chlorination primary acid absorption tower from the tail gas. The chlorinated liquid is discharged from the bottom of the gas-liquid separator 2 to the chlorine-eliminating kettle 1 with a slingering tray 9 to remove chlorine. This process greatly reduces the workload of the subsequent chlorine-eliminating kettle 1.

[0030] After the chlorinated liquid enters the chlorine-eliminating kettle 1, it flows into the chlorine-eliminating tray 8, the center of which is connected to the stirring shaft 7 of the motor. The chlorine-eliminating tray 8 generates centrifugal force when it rotates, which flings the chlorinated liquid toward the wall of the chlorine-eliminating tray 8. After passing through the small holes on the wall of the chlorine-eliminating tray 9, it is divided into droplets and eventually reaches the inner wall of the chlorine-eliminating kettle 1. The droplets are continuously heated as they flow downward along the kettle wall, and chlorine and hydrogen chloride are separated from the reaction solution. They are then absorbed by the tail gas pipeline into the chlorination primary acid absorption tower. The chlorinated liquid that has passed the chlorine-eliminating tray 9 is directly discharged from the bottom of the chlorine-eliminating kettle 1 to the chlorination liquid tank 4.

[0031] The structure of the chlorine-eliminating plate 8 is described. The chlorine-eliminating plate 8 includes a spinner 9. A baffle 10 is provided at the edge of the spinner 9. A plurality of through holes 11 are provided in the baffle 10. The through holes 11 serve as droplet outlets. The diameter of the spinner 9 is 1000 mm, the height of the baffle 10 is 20 mm, and the diameter of the through holes 11 is 10 mm.

[0032] Furthermore, the spinning disc 9 is made of steel lined with PTFE.

[0033] Optionally, one side pipeline of the gas-liquid separator 2 is connected to the outlet material pipeline 5 of the external continuous flow reactor, so that the mixture of chlorinated liquid and chlorine gas and hydrogen chloride enters the gas-liquid separator 2 after being discharged from the continuous flow reactor.

[0034] The present disclosure removes chlorine through the chlorine removal plate 8, which can effectively improve the overall continuous flow reaction compared to the existing method using multiple chlorine removal kettles 1, thereby increasing the production rhythm and production efficiency of the entire process of chlorination and technical.
