Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ammonium chloride production equipment, in particular to an ion exchange column used for efficiently removing ammonia nitrogen from tail water in the production of ammonium chloride. Background Art
[0002] Ammonium chloride is produced as a byproduct during the production of copper sulfate. The acid and alkaline copper-containing etching waste liquids are mixed and adjusted with ammonia water to produce a neutralization reaction to generate a precipitate. After the first filter press, the filter cake is slurried with an appropriate amount of water and then filtered for the second time. The filtrate is passed through an ion exchange resin to remove residual copper ions and then enters a double-effect evaporation tower. Ammonium chloride crystals can be recovered by evaporation, cooling and crystallization. The copper sulfate production process produces copper-containing ammonium chloride wastewater. After the residual copper ions and other impurity metal ions are removed through a cation exchange column, it enters a double-effect evaporation system for concentration production to obtain ammonium chloride crystal byproducts.
[0003] The double-effect evaporation system requires condensed water for concentration production. The condensed water needs to be collected and reused after production is completed. However, the collected condensed water contains chlorine and nitrogen components and cannot be put into use directly. It needs to be treated to remove ammonia nitrogen first. Generally, ion exchange technology is used. However, conventional ion exchange towers can only perform a single exchange, and the condensed water may not meet the usage standards after treatment.

[0008] As a further improvement of the utility model, one side of the three-way valve pipe is fixedly connected to a collecting pipe, and the other end of the collecting pipe is fixedly connected to a condensation water tank.
[0009] As a further improvement of the utility model, a second water pump is fixedly connected to the upper surface of the base, the water outlet end of the second water pump is fixedly connected to a water inlet pipe, the other end of the water inlet pipe is fixedly connected to the tower cover, and the water pumping end of the second water pump is fixedly connected to a water pumping pipe.
[0010] As a further improvement of the utility model, a visual glass is fixedly installed on the front of the condensation water tank, and a recovery valve pipe is fixedly connected to one side of the condensation water tank.

[0012] Beneficial effects of the utility model:
[0013] By setting up an ion exchange tower, when in use, the water suction pipe is connected to the used condensed water, and the second water pump is started to input the condensed water containing ammonia nitrogen into the ion exchange tower through the water inlet pipe, and ions are exchanged with the cation exchange resin in the ion exchange tower, so that the device can simply treat the condensed water containing ammonia nitrogen and effectively reduce the ammonia nitrogen content in the condensed water.
[0014] By setting up a detection structure, when in use, the condensed water after the reaction is completed enters the transfer barrel through the outlet pipe, and the water quality detector detects the ammonia nitrogen content therein. If the ammonia nitrogen content is too high, the first water pump is started and the three-way valve pipe is turned to continue to input the condensed water through the circulation pipe into the ion exchange tower for secondary exchange reaction. When the ammonia nitrogen content of the condensed water meets the standard, the three-way valve pipe is turned to input the condensed water through the collection pipe into the condensed water tank for recycling, so that the device can perform multiple ion exchange treatments on the condensed water until the ammonia nitrogen content in the condensed water meets the standard, thereby avoiding the situation where the ammonia nitrogen content of the condensed water is still too high after the reaction, thereby increasing the availability of the device.
