Product Description
The LTV-500 Low Temperature Wastewater Evaporator is a high-efficiency energy-saving vacuum evaporation wastewater treatment equipment independently developed based on advanced heat pump vacuum evaporation technology. It is widely applied in industrial wastewater concentration and purification scenarios, especially suitable for treating cleaning wastewater containing flux, cleaning agent and oil impurities such as PCBA rinsing water and fixture cleaning wastewater.
The equipment stably controls the evaporation temperature at 28-37℃ under high vacuum negative pressure, realizing low-temperature boiling and evaporation of wastewater without high-temperature heating. The wastewater recovery rate can reach 90%–95%, while only 5%–10% of high-concentration oil substances, residual cleaning liquid and flux concentrated residues are left and collected in the waste liquid barrel for subsequent centralized treatment, which greatly reduces wastewater discharge volume and enterprise environmental pressure.
Equipped with adjustable steam thermal compression ejector, precision heat transfer tubes and advanced three-way airflow components, the equipment optimizes the overall process system and core parameters. It precisely controls the effective heat transfer temperature difference within 2℃, achieving ultra-high heat exchange efficiency and excellent energy-saving performance. The whole machine adopts intelligent PLC control to realize continuous automatic operation, supporting unattended all-weather operation, which effectively reduces manual operation cost and improves wastewater treatment efficiency and stability.
Working Process
1. Filtration and Feeding: Industrial wastewater enters the equipment after being intercepted and filtered by the front-end feed filter to block crystal impurities and prevent pipeline blockage, ensuring smooth feeding.
2. Low-Temperature Vacuum Evaporation: The system forms a stable high negative pressure vacuum environment of -0.096~-0.098Mpa. The wastewater is heated by the immersed high-efficiency heat exchanger and evaporates steadily at 28-37℃ low temperature.
3. Vapor Condensation & Water Recovery: The evaporated water vapor is condensed and recovered into clean distilled water through the precision heat exchange system, with a recovery rate up to 90%-95% for recycling.
4. Concentrated Residue Discharge: High-concentration oil, flux and impurity residues that cannot be evaporated are automatically concentrated and settled, and the concentrated waste liquid is regularly discharged into the waste liquid barrel.
5. Automatic Maintenance & Operation: The equipment automatically feeds defoamer according to working conditions, matches automatic slag discharge and pipeline self-cleaning functions, and realizes continuous cycle operation without manual intervention.
Core Technical Features
1. Premium Anti-Corrosion Material Configuration: Both the evaporator main body and the annular coil heat exchanger are made of 316L stainless steel, which is resistant to acid, alkali, oil and chemical corrosion, adapting to complex industrial wastewater working conditions and extending equipment service life.
2. High-Efficiency Immersed Heat Exchange Structure: Adopts immersed heat exchanger design with large heat exchange intensity and high thermal efficiency. The optimized 2℃ tiny heat transfer temperature difference realizes rapid and uniform heating, greatly improving evaporation efficiency and energy utilization rate.
3. Dual Anti-Blockage Protection System: Equipped with front-end feed filter for crystal interception and built-in automatic pipeline cleaning function, which effectively avoids pipeline scaling and blockage during long-term operation and ensures long-term stable and smooth equipment operation.
4. Fully Automatic Unmanned Operation: Integrated PLC intelligent control system and touch human-machine interface, supporting one-click start/stop, automatic waste liquid feeding, automatic defoamer dosing and automatic slag discharge. It realizes 24-hour continuous unattended operation and reduces labor costs.
5. Fully Enclosed Negative Pressure Operation: The whole machine operates in a closed negative pressure state, completely preventing harmful gas and steam leakage, ensuring safe and environmentally friendly production with zero pollution overflow.
6. Low-Temperature Anti-Scaling Stable Operation: Constant low-temperature evaporation at 28-37℃ avoids high-temperature scaling and equipment aging problems of traditional evaporators. The equipment is easy to clean, stable in operation and low in failure rate.
7. Advanced Energy-Saving System: Matches adjustable steam thermal compression device and international advanced airflow three-way components. Through systematic optimization and core component verification, it achieves ultra-low energy consumption operation and excellent energy-saving effect.
