Pesticide between organic waste water extract hydroxyl benzoic acid operation process

by:Deyuan      2020-08-14
Between the hydroxyl benzoic acid is a kind of chemicals, slightly soluble in water and benzene, soluble in ethanol and ether. Between the hydroxyl benzoic acid is mainly used as a fungicide, coating, preservatives, ion exchanger, synthetic azo dye, plasticizer and pharmaceutical intermediates, etc. Therefore pesticide companies often use this kind of material.

in pesticide production and processing will produce large amounts of hydroxyl benzoic acid waste water, the need for solvent extraction, extraction between hydroxyl benzoic acid.

solvent extraction is a liquid liquid extraction, extraction by organic phase and water phase are mixed, water phase to separate the material into the organic phase, again by two phase mass density different separate two phase.

when making between hydroxyl benzoic acid waste water extraction, choose suitable extractant, between hydroxyl benzoic acid wastewater with the extracting agent according to certain proportion respectively from different entrance into centrifugal extraction machine, with the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer, mixing and mass transfer process. Mixture again after the effect of drum centrifugal force through two separate out of the body side by side.

chose between centrifugal extraction machine of hydroxy benzoic acid extraction separation, because centrifugal extraction machine compared with traditional extraction equipment, centrifugal extraction machine is the use of motor driven rotary drum high-speed rotation, the density of different and each of two immiscible liquids in drum or under the action of shear force produced by the rotation of blades complete mixing and mass transfer, and the effects of the centrifugal force in the high-speed rotating drum under rapid separation.

if want to learn more about centrifugal extraction machine operating principles and process, can contact extraction technology co. , LTD. Zhengzhou days!
