Solvent extraction of triazine ketone operation process and equipment selection

by:Deyuan      2020-09-04
Triazine ketone is mainly used in the manufacture of pesticide products of intermediate of oxazine grass, enterprises in the process of production and processing will produce large amounts of triazine ketone wastewater, which also contains pivalic acid composition. Sometimes such waste water high chroma, have peculiar smell, for adverse impact on the surrounding environment, the problem of environmental pollution is becoming more and more serious. Therefore, in accordance with the need of this kind of wastewater processing first, and then to emissions.

for there are many ways of organic waste water treatment, but combined with the comprehensive cost, solvent extraction wastewater treatment effect is remarkable. Solvent extraction is not only less equipment investment, cover an area of an area small, and low energy consumption, easy operation, at the same time, also can have value in waste water recycling material.

the operation of the solvent extraction process is: waste water containing a triazine ketone and other organic matter compared with extraction agent according to certain through different inlet into the centrifugal extraction equipment, will be a full hybrid two-phase liquid mass transfer, in the wastewater organic matter triazine ketone will shift to the extraction agent, and then through rapid separation and shear force of two phase fluid through different export eduction body, complete extraction process. Organic compounds were extracted, and then through the extraction, separation of extraction solvent with the organic matter, organic matter recycling, extraction solvent regeneration for reuse, and more than extraction liquid through the subsequent biochemical treatment to achieve discharge standard.

extraction chemical organic wastewater recycling equipment is mainly adopted by the reaction kettle, extraction, extraction tower, centrifugal extraction machine, etc. Compared with other traditional equipment, the obvious advantages of centrifugal extraction machine, high extraction efficiency, simple and convenient operation, low power consumption, capacity is bigger, so is widely used in many fields of extraction section.

advantage of centrifugal extraction machine:

1, the equipment has simple structure, stable, structure of suspension single fulcrum, processing area at the bottom of the bearing and mechanical seal, no leakage risk, save the costs for equipment maintenance.

2, equipment capacity bigger, more energy saving.

3, the equipment can choose using perfluorinated polymer materials, resistant to strong acid, Hydrochloric acid and mixed acid, etc. ) The corrosion.

4, mixing, separation effect is good, — A variety of hybrid structure is optional, high separation efficiency, can be applied to easily emulsifying system.

5, a high degree of automation, — Can realize online real-time monitoring equipment operation data, fully able to adapt to the intermittent and continuous operation.
