Water purification device

Abstract

The invention discloses a water purification device. The water purification device comprises a raw water tank, a raw water pump, a pretreatment part, a filtering water tank, a primary high-pressure pump, a reverse osmosis part, a primary pure water tank, an EDI treatment part and a secondary pure water tank, wherein the raw water tank, the raw water pump, the pretreatment part, the filtering watertank, the primary high-pressure pump, the reverse osmosis part, the primary pure water tank, the EDI treatment part and the secondary pure water tank are connected in sequence through pipelines; thepretreatment part is communicated with a water softener, a pH adjusting and chemical feeder is arranged on a first pipeline, the reverse osmosis part is communicated with a cleaning water tank, and communicated with a reverse osmosis concentrated water tank, and the reverse osmosis part concentrated water tank is communicated with the second reverse osmosis part body; the second reverse osmosis part body is communicated with the filtering water tank, the cleaning water tank and a concentrated water storage tank, and a cleaning part is communicated with a pipeline connecting the primary high-pressure pump and the reverse osmosis part, communicated with the pretreatment part and connected with a control module through a circuit. The water purification device has the advantages that automaticcleaning is achieved, pipelines do not easily get clogged, the water purification efficiency is high, circular sewage treatment is achieved, and the sewage discharge amount is small.
