1results about How to "Reduce ammonia content" patented technology

The utility model provides a continuous production device for EDTA (Ethylene Diamine Tetraacetic Acid) condensation reaction, which belongs to the technical field of chemical equipment and comprises a reaction deamination tower, a first heat exchanger, a second heat exchanger and a blender, a tubular heat exchanger is arranged at the top of the reaction deamination tower, and an ammonia discharge pipe is arranged at the top of the tubular heat exchanger; the materials subjected to heat exchange by the second heat exchanger and the materials subjected to heat exchange by the first heat exchanger are mixed in the blender; and the mixer is communicated with the reaction deamination tower through a mixture feeding pipe. An extraction pipe is arranged at the bottom of the reaction deamination tower, part of high-temperature reaction liquid extracted from the bottom of the reaction deamination tower by a ramming circulating pump on the extraction pipe enters the first heat exchanger and the second heat exchanger for heat exchange, and part of the high-temperature reaction liquid enters the blender through a circulating communicating pipe for material mixing. By utilizing the device, the ammonia discharge effect and the ammonia discharge timeliness can be improved, the product quality after the EDTA condensation reaction can be improved, the land can be saved, and the production cost, the energy consumption and the labor intensity can be reduced.
