The invention discloses tetrachloroethylene deoxidization and dehydration equipment. The equipment comprises a feed pump, a deoxidization drying tower, filters and a finished product tank, which are sequentially communicated, wherein the deoxidization drying tower comprises a tower body, and an end enclosure is arranged at each of the upper and lower ends of the tower body; the tower body is divided into an upper section, a middle section and a lower section, each of which is filled with an alkali filler and a molecular sieve; filler support grid plates are arranged on the lower and middle parts of the tower body respectively; stainless steel meshes are laid on the filler support grid plates; filler pressing plates are arranged on the upper parts of the fillers in the tower body; a feed port is formed in the central position of the upper end enclosure, and a discharge port is formed in the central position of the lower end enclosure; the filters I are arranged at the feed port and the discharge port, and a buffer plate is arranged at the feed port; a detachable distribution plate is arranged below the buffer plate; flow baffle plates are arranged below the filler support grid plates. According to the equipment, water in tetrachloroethylene is reduced, the PH value of tetrachloroethylene is increased, influence on the purity of tetrachloroethylene is avoided, and high chromaticity is ensured; a closed circulation mode is adopted for a system, waste residues and wastewater are avoided, and the equipment is easy to operate, safe and reliable.
