Designed for high-concentration saline waste liquid (TDS ≥ 10,000mg/L) from various industries, the equipment submerges the atomized waste liquid directly into high-temperature molten salt (850–1100℃), realizing instant evaporation, organic oxidation, and salt vitrification in one step. This unique process eliminates the risk of scaling and blockage, ensures efficient treatment, and converts waste into reusable resources, helping enterprises achieve environmental compliance and cost optimization.

Product Feature
Core Working Principle
The Submerged Combustion Furnace integrates atomization, high-temperature oxidation, molten salt absorption, and vitrification, with a streamlined, efficient working process that ensures thorough treatment and stable operation:
1、Preprocessing & Atomization: The high-concentration saline waste liquid is first filtered to remove large impurities and then atomized into fine droplets by a corrosion-resistant high-pressure atomizer. This ensures full contact between the waste liquid and the high-temperature molten salt, maximizing treatment efficiency.
2、Submerged High-Temperature Oxidation: The atomized waste liquid droplets are directly injected into the high-temperature molten salt (850–1100℃) in the furnace chamber. The molten salt acts as a heat carrier, instantly evaporating the water in the waste liquid, while organic pollutants are completely oxidized and decomposed into harmless CO₂ and H₂O. Salt components in the waste liquid are dissolved and integrated into the molten salt system.
3、Vitrification & Resource Utilization: As the salt content in the molten salt increases, the excess molten salt is continuously discharged into a cooling system, rapidly solidifying into inert, non-leaching vitrified slag. This vitrified slag is non-toxic, stable in chemical properties, and can be recycled as building materials or safely landfilled. The flue gas generated during the process is treated by waste heat recovery, dust removal, and desulfurization before reaching emission standards, and the recovered heat is reused for production.
Key Product Advantages
1、Superior Treatment Efficiency: The submerged design ensures direct contact between waste liquid and high-temperature molten salt, with organic decomposition rate ≥ 99.5% and salt vitrification rate 100%. It efficiently handles high-concentration saline waste liquid (TDS up to 100,000mg/L) and high-COD waste liquid, ensuring discharge meets global environmental standards.
2、Anti-Scaling & Anti-Blockage: Unlike traditional evaporation or incineration equipment, the submerged process avoids the formation of salt scale on furnace walls and pipelines, eliminating blockage risks, reducing maintenance frequency, and ensuring long-term stable operation.
3、Corrosion & High-Temperature Resistance: The furnace body, atomizer, and key components are made of high-quality corrosion-resistant and high-temperature-resistant alloy materials, which can withstand the strong corrosion of high-salt, high-acid, and high-alkali waste liquid, extending equipment service life.
4、Zero Secondary Pollution: The entire treatment process generates no wastewater, sludge, or harmful by-products. Organic pollutants are completely oxidized into CO₂ and H₂O, and salt is converted into recyclable vitrified slag, achieving true zero secondary pollution.
5、Energy-Saving & Cost-Effective: Equipped with a high-efficiency waste heat recovery system, heat recovery efficiency reaches ≥ 90%. The recovered waste heat is used to preheat the waste liquid and maintain molten salt temperature, greatly reducing auxiliary fuel consumption and operating costs. The recyclable vitrified slag also creates additional economic value.
6、Stable & Safe Operation: Adopts micro-negative pressure furnace design and multiple safety interlock protection systems (explosion relief, over-temperature alarm, flameout protection, molten salt level monitoring, leakage detection), effectively preventing risks such as deflagration, over-temperature, and molten salt leakage, adapting to high-risk industrial scenarios.
7、Intelligent Automatic Control: Equipped with PLC intelligent control system, it realizes automatic feeding, automatic temperature adjustment, automatic slag discharge, remote monitoring, and fault alarm, supporting 24-hour unattended operation, reducing manual management costs and ensuring stable operation parameters.
8、Compact & Easy to Install: Modular integrated design, small footprint, easy to install, disassemble, and expand. It can be prefabricated in the factory and quickly assembled on site, shortening the construction and commissioning cycle, suitable for both new projects and old factory renovation.
9、Strong Adaptability: It can adapt to large fluctuations in salt concentration, COD value, and viscosity of waste liquid, stably handling high-salt waste liquid from different industries, with strong anti-impact load capacity and wide applicability.
