Abstract

The invention discloses a salt slurry elutriation and purification system for an evaporation-method salt-nitrate co-production process and a salt-nitrate co-production system. The salt slurry elutriation and purification system comprises a salt discharge buffer tank, a first salt slurry pump, a cyclone, an elutriation salt slurry barrel, a second salt slurry pump, an elutriation overflow thickener, a salt centrifuge and a salt drying device which are sequentially arranged behind a salt discharge foot of a salt group tank of the evaporation-method salt-nitrate co-production system. The system is relatively low in transformation cost, water and halogen balance in the system is maintained on the basis of not interfering with operation of an existing system, the purity of finished salt can beimproved to 99.9%, energy consumption cannot be greatly increased, and economic benefits are remarkable.

Description

technical field [0001] The invention relates to the technical field of evaporation method salt and nitric acid cogeneration equipment, in particular to a salt slurry elutriation purification system and a salt and nitric acid cogeneration system for the evaporation method salt and nitric acid coproduction process. Background technique [0002] At higher than normal temperature, NaCl-Na 2 SO 4 -H 2 O brine system shows that the solubility of NaCl increases with the increase of temperature, and the solubility of NaCl 2 SO 4 Solubility tends to decrease with the increase of temperature. Based on this characteristic, domestic mineral salt basically adopts the process of co-production of salt and nitrate by evaporation method to produce salt and nitrate (see figure 1 ). [0003] Theoretically, according to NaCl-Na 2 SO 4 -H 2 The solubility characteristics of the solute in the O brine can realize the extraction of nearly 100% pure NaCl and Na through cold crystallization a...
