Antimony pentachloride waste liquid treatment system

Abstract

The invention provides an antimony pentachloride waste liquid treatment system. The antimony pentachloride waste liquid treatment system mainly comprises a primary reaction kettle and a secondary reaction kettle, wherein the primary reaction kettle is sequentially connected to a vacuum filtration machine, a first-stage filtrate tank, a first pipeline pump and the secondary reaction kettle; the secondary reaction kettle is sequentially connected to a filter press, a secondary-stage filtrate tank, a second pipeline pump and a wastewater treatment system; the primary reaction kettle is sequentially connected to a graphene condenser, a liquid distribution tank and a first-stage falling film absorption tower, and the liquid distribution tank is respectively connected to a dilute acid storage tank and a chloroform storage tank; the first-stage falling film absorption tower is sequentially connected to a fourth pipeline pump, the first-stage falling film absorption tower, a secondary-stage falling film absorption tower and a third pipeline pump; the secondary reaction kettle, the first-stage filtrate tank and the secondary-stage falling film absorption tower are connected to a vacuum buffer tank which is connected to a vacuum pump. The antimony pentachloride waste liquid treatment system can be used for recovering antimony oxide in waste liquid very well and collecting acid gas and chloroform generated in a reaction process and is complete in treatment and good in effect.

Description

technical field [0001] The invention relates to a system for disposing antimony pentachloride waste liquid to recover antimony oxide, and belongs to the technical field of antimony pentachloride waste liquid disposal. Background technique [0002] The composition of antimony pentachloride waste liquid is complex, and the existing recovery process and equipment often ignore the collection and recovery of acidic components and chloroform, which causes damage to the surrounding atmospheric environment and causes and harms the health of surrounding environmental workers. [0003] Chinese patent document CN102220496A discloses a method for reclaiming antimony pentoxide from waste fluorination catalyst antimony pentachloride, A. extraction, extracting waste fluorination catalyst antimony pentachloride with extractant to obtain antimony ion-containing inorganic phase extract; B, oxidation, the inorganic phase extract is oxidized with an oxidant to obtain an antimony oxidation solut...
