Low temperature evaporator mother liquor concentration wastewater treatment equipment

One working principle

Low temperature evaporator mother liquor concentration wastewater treatment equipmentBy relying on a heat pump system to provide an efficient heat source, combined with a vacuum negative pressure environment to reduce the boiling point of the mother liquor, the mother liquor can quickly evaporate water at a low temperature of 30-40 ℃; The steam generated by evaporation is converted into distilled water that can be reused or discharged in compliance with standards through the condensation system. The mother liquor is then concentrated due to continuous separation of moisture (reducing the moisture content to 10% -15%), efficiently completing the reduction and concentration treatment of the mother liquor.

II Features of the equipment

Efficient and energy-saving:

Low temperature evaporator mother liquor concentration wastewater treatment equipmentThe processed distilled water can be recycled and reused, achieving water resource recycling.

Intelligent stability:

Siemens PLC control system+remote monitoring APP, real-time monitoring of operating data, supporting unmanned operation.

Corrosion resistant and durable:

The evaporation tank body is made of 316L stainless steel or titanium material, which can withstand strong acid and alkali environments with pH 2-12, and has a service life of over 10 years.

Special anti-corrosion coating treatment, suitable for complex mother liquors containing heavy metals and organic solvents.

Flexible customization:

The processing capacity range is 0.001-10T/h, supporting modular design, occupying only 1-10 square meters, and can be quickly installed and debugged.

Provide customized solutions for different water qualities (such as high salt, high oil, and heat sensitivity), such as precise recovery of solvents such as ethanol and acetone from pharmaceutical wastewater, with a recovery rate of ≥ 95%.

III Application Cases

Chemical industry: Reduction of high salt mother liquor

A certain chemical enterprise produces 3600 tons of high salt mother liquor (TDS ≥ 30000mg/L) annually. After adopting our low-temperature scraper crystallization evaporator, the volume of the mother liquor is reduced by 85%, and the annual production of ammonium sulfate crystals is 120 tons. The cost of hazardous waste disposal is reduced by 70%.

Electroplating industry: reuse of heavy metal wastewater

After equipment treatment, the nickel ion concentration in the nickel containing wastewater (80mg/L nickel ion, COD 3000mg/L) from a certain electroplating enterprise decreased to below 0.1mg/L. The reuse rate of distilled water reached 85%, saving 15000 tons of water annually and reducing the amount of hazardous waste disposal by 90%.

Pharmaceutical industry: Thermal wastewater treatment

The antibiotic fermentation broth (containing thermosensitive components) from a certain pharmaceutical factory is evaporated at a low temperature of 30-40 ℃, with a retention rate of over 95% for active ingredients, and 0.8 tons/day of ethanol is recovered.

Garbage leachate treatment: fully quantified disposal

A certain hazardous waste disposal unit processes 20 tons of leachate per day, combined with the "pretreatment+low-temperature evaporation+mother liquor drying" scheme, the produced water is reused for flushing the system, and the water content of the concentrated solution is reduced to below 10%.
