Description

Technical Field

[0001] This utility model relates to the field of chlorine absorption technology, specifically a device for absorbing chlorine using ferrous chloride solution. Background Technology

[0002] Currently, chlorine absorption is mainly carried out through ferrous chloride absorption towers. The absorption of chlorine using ferrous salt solutions is a redox reaction, with the following reaction formulas: Absorption (oxidation) reaction: 2Fe2++Cl2=2Fe3+ +2Cl-; Regeneration (reduction) reaction: 2Fe3++Fe=3Fe2+. This method can absorb a large amount of chlorine at once, far exceeding the rated absorption capacity.

[0003] Currently, when using ferrous chloride solution to absorb chlorine gas, it is important to pay attention to the concentration of ferrous iron in the solution and keep the Fe2+ concentration at no less than 20 g / L. When the Fe2+ concentration drops to around 20 g / L, the absorbent solution needs to be replaced to prevent chlorine gas from escaping and endangering safety.

[0004] Therefore, a device is needed to absorb chlorine gas using ferrous chloride solution to improve the above-mentioned problem. Utility Model Content

[0025] A device for absorbing chlorine gas using ferrous chloride solution includes a chlorine absorption tower 1, a support leg 2 on the lower side of the outer wall of the chlorine absorption tower 1, a liquid addition pipe 3 on the lower left side of the chlorine absorption tower 1, a first solenoid valve 4 installed on the liquid addition pipe 3, an air inlet pipe 5 in the middle of the front of the chlorine absorption tower 1, a second solenoid valve 6 installed on the air inlet pipe 5, a solution concentration detector 7 installed inside the chlorine absorption tower 1, a drain pipe 8 at the bottom of the chlorine absorption tower 1, a third solenoid valve 9 installed on the drain pipe 8, an information processing controller 10 installed on the lower front of the chlorine absorption tower 1, a liquid extraction pipe 11 on the lower right side of the chlorine absorption tower 1, a liquid extraction pump 12 installed on the upper side of the liquid extraction pipe 11, a circulation pipe 13 installed on the upper side of the liquid extraction pump 12, a spray pipe 14 on the upper side of the interior of the chlorine absorption tower 1, and spray nozzles 15 evenly installed on the lower side of the spray pipe 14.

[0026] In this embodiment, the solution concentration detector 7 is connected to the information processing controller 10 via a wire, and the connection is electrical. The information processing controller 10 is also electrically connected to the first solenoid valve 4, the second solenoid valve 6, and the third solenoid valve 9. The information processing controller 10 is also electrically connected to the liquid pump 12. The circulation pipe 13 runs through the chlorine absorption tower 1 and is connected to the spray pipe 14. The support leg 2 has three parts and is integrally formed with the chlorine absorption tower 1. Through the liquid addition pipe 3, the first solenoid valve 4, the air inlet pipe 5, the second solenoid valve 6, the solution concentration detector 7, the liquid discharge pipe 8, the third solenoid valve 9, the information processing controller 10, the liquid extraction pipe 11, the liquid pump 12, and the circulation pipe 13, the ferrous chloride solution can be replaced in time when the concentration of the ferrous chloride solution decreases, thereby improving the chlorine absorption effect.

[0027] The working process of this utility model is as follows: First, open the first solenoid valve 4 to add ferrous chloride solution into the chlorine absorption tower 1. Then, open the second solenoid valve 6 to add chlorine gas into the chlorine absorption tower 1 through the inlet pipe 5. Next, start the liquid pump 12 to draw the ferrous chloride solution into the spray pipe 14 through the liquid pumping pipe 11 and the circulation pipe 13. Then, the ferrous chloride solution is sprayed out from the nozzle 15. At this time, the ferrous chloride solution will chemically react with and absorb the chlorine gas. Then, the concentration of the ferrous chloride solution will decrease. At this time, the solution concentration detector 7 will detect the concentration of the ferrous chloride solution. When the concentration of the ferrous chloride solution can no longer absorb chlorine gas, open the third solenoid valve 9 to discharge the ferrous chloride solution. Then, open the first solenoid valve 4 again to add ferrous chloride solution into the chlorine absorption tower 1. Repeat the above steps until the chlorine absorption is completed.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
