Facing the pain points of difficult disposal, high energy consumption and low recovery rate of industrial waste salt, Baihuipu Pure Vacuum Evaporation Salt Machine, with core low-temperature vacuum evaporation and crystallization technology, has been successfully exported to Sri Lanka, providing a low-energy, high-purity, fully automatic waste salt recycling solution for local chemical, printing and dyeing, and mining enterprises. As an emerging industrial country in South Asia, Sri Lanka has a large amount of waste salt by-products from chemical and mining industries. Traditional landfilling easily causes soil and groundwater pollution, while imported equipment is costly and difficult to maintain, creating an urgent need for cost-effective pure vacuum evaporation salt equipment. Baihuipu Pure Vacuum Evaporation Salt Machine accurately adapts to local working conditions. With mature technology and stable performance, it helps Sri Lankan enterprises realize "reduction, harmlessness and recycling" of waste salt, in line with local environmental regulations and sustainable development requirements.
Core Process & Technical Equipment
Baihuipu Pure Vacuum Evaporation Salt Machine adopts an integrated process of high-vacuum low-temperature evaporation + continuous crystallization + automatic salt discharge. The core system consists of a vacuum unit, evaporation crystallizer, heat exchange system and automatic control unit. Operating at a high vacuum of -0.07~-0.09MPa, the boiling point of brine drops to 45–60℃, reducing energy consumption by 30%+ compared with traditional high-temperature evaporation and avoiding scaling and salt quality deterioration. The evaporation chamber is made of 316L/2205 duplex steel for corrosion resistance, equipped with internal forced circulation stirring and anti-scraping blades to ensure uniform salt evaporation and controllable crystal particle size (0.5–1mm), with salt purity reaching 98%+. The entire equipment features fully automatic DCS control with real-time monitoring of over 70 parameters and 24/7 unattended operation. Condensed water can be reused or discharged up to standard, truly achieving "zero discharge, high recovery and low operating cost".
Sri Lanka Case Study
Baihuipu has implemented 2 benchmark projects in the Western Province Chemical Industrial Park of Sri Lanka, processing chemical by-product sodium chloride/sodium sulfate waste salt with a capacity of 5–15 tons/day. The projects adopt Baihuipu Pure Vacuum Evaporation Salt Machine, with fully automated operation from waste salt dissolution, vacuum evaporation, crystallization separation to salt drying and packaging. Since commissioning, the equipment has operated stably for 18 months without major maintenance, with a waste salt recovery rate of ≥95% and industrial salt purity of ≥98.5%, which can be directly reused in chemical production or sold externally. Condensed water COD is less than 50mg/L, fully complying with Sri Lanka’s Central Environmental Authority discharge standards. The projects have significantly reduced customers’ hazardous waste disposal costs (by 60%+) and generated additional revenue through salt resource recovery, earning high recognition from local environmental authorities and clients, and becoming a model project for waste salt recycling in South Asia.
