Abstract

Equipment for efficiently treating quinacridone production wastewater is provided, which comprises a reaction tower. The reaction tower is provided with a first spraying layer, a second spraying layerand a turbulence layer inside. The first spraying layer includes a plurality of first spraying pipes distributed in a pipe network manner. The first spraying pipes are provided with a plurality of first nozzles. An included angle a is between the plane where the first spraying layer is and the spraying directions of the first nozzles, and the spraying directions of each two of the first nozzles intersect with each other. The second spraying layer includes a plurality of second spraying pipes provided with a plurality of second nozzles. An included angle b is between the plane where each second spraying pipe is and the spraying direction of the corresponding second nozzles. The turbulence layer includes a plurality of turbulence plates provided with through holes. The a is less than 90 degrees and greater than 30 degrees, and the b is greater than 0 degree and less than 90 degrees. The equipment can avoid problems of uneven mixing of the slurry and high temperature, and can improve thewastewater treatment efficiency.

Description

technical field [0001] The invention relates to the field of quinacridone production technology, in particular to a high-efficiency treatment equipment for quinacridone production wastewater. Background technique [0002] During the production process of quinacridone, a large amount of phosphorus-containing wastewater will be produced. The generation of phosphorus-containing wastewater is mainly due to the use of polyphosphoric acid in the synthesis process of quinacridone. At present, calcium hydroxide obtained by emulsification of lime is usually used to carry out acid-base neutralization reaction with phosphorus-containing wastewater. On the one hand, the phosphorus content in wastewater can be greatly reduced, and on the other hand, calcium hydrogen phosphate products can be produced. [0003] In the prior art, phosphorus-containing wastewater directly enters the reaction tower and is emulsified with lime. After emulsification, the coarse residue is filtered out, and the...
