A continuous extraction device for recovering trichlorophenol from pyrithiobencarb

Abstract

The application relates to a device for continuously extracting and recovering trichlorophenol from prochloraz, and relates to the technical field of trichlorophenol, which comprises a hydrochloric acid tank, an alkaline wastewater tank, a dichloroethane tank, a first mixer, a first continuous extractor, an acid washing water layer tank, an acid washing oil layer tank, a liquid alkali tank, a second mixer, a second continuous extractor, an alkali washing oil layer tank and an alkali washing water layer tank, the hydrochloric acid tank, the alkaline wastewater tank and the dichloroethane tank are connected with the first mixer through pipes, and the first mixer is connected with the first continuous extractor through a pipe, the complete connection system of the hydrochloric acid tank, the alkaline wastewater tank, the dichloroethane tank, two-stage mixers, two-stage continuous extractors and multiple layering tanks realizes a continuous extraction and recovery process of trichlorophenol in prochloraz amination wastewater, the structure does not need to set a solid-liquid separation link, the process steps are simplified, and meanwhile, the processing capacity is improved through a closed continuous operation design.
