Single-Effect Evaporator

Sodium chloride single-effect evaporators are highly efficient and energy-saving integrated concentration/crystallization devices specifically developed for NaCl solutions. They employ either "forced circulation + mechanical vapor recompression (MVR)" or "single-effect + live steam thermal compression (TVR)" process packages, resulting in a comprehensive operating cost reduction of over 50% compared to traditional triple-effect evaporators. They are widely used in the resource recovery of sodium chloride and "zero discharge" of wastewater in industries such as chlor-alkali, dyes, pharmaceuticals, coal chemicals, and seawater desalination brine.

Sodium nitrate is an important inorganic chemical raw material, widely used in fertilizers, explosives, dyes, and glass manufacturing. In the production and recovery of sodium nitrate, evaporation and crystallization are key processes, directly affecting the purity and yield of the product. Our single-effect sodium nitrate evaporator is specifically designed for sodium nitrate solutions, providing an efficient, stable, and reliable evaporation and crystallization solution.

Sodium cyanide is a highly toxic chemical, and the treatment of cyanide-containing wastewater generated during its production and use is a top priority in environmental protection. Improper treatment can not only cause serious environmental pollution but also endanger human lives. Our sodium cyanide single-effect evaporator adopts a fully enclosed design and multiple safety protection measures, providing the safest and most reliable evaporation and concentration solution for cyanide-containing wastewater treatment.

The electrolytic aluminum production process generates a large amount of lithium-containing aluminum electrolyte waste residue. This residue contains valuable lithium resources, and traditional treatment methods not only waste resources but also pose environmental pollution risks. Our single-effect evaporator system for lithium extraction from aluminum electrolyte is specifically designed to extract lithium resources from aluminum electrolyte, maximizing the resource utilization of waste residue and economic benefits.

In industries such as chemical, pharmaceutical, and environmental protection, the treatment of sodium sulfate wastewater has always been a major challenge for enterprises. Traditional evaporation equipment is not only energy-intensive and requires a large area, but also has low automation and is difficult to operate. To address this pain point, we have launched the sodium sulfate MVR single-effect evaporator, which employs advanced mechanical vapor recompression (MVR) technology to provide customers with a highly efficient, energy-saving, and environmentally friendly evaporation crystallization solution.

Coking wastewater is a high-concentration organic wastewater generated during coking, coal gas purification, and chemical product recovery processes. It contains various toxic and harmful substances such as phenols, cyanides, ammonia nitrogen, and sulfides. Its complex composition and high treatment difficulty make it a key and challenging area in industrial wastewater treatment.

A forced circulation single-effect evaporator is an evaporation device that utilizes external power for feed liquid circulation. Forced circulation single-effect evaporators play an important role in the evaporation and concentration of difficult industrial wastewater and high-viscosity liquids due to their rapid, stable, and highly adaptable characteristics.​

This MVR single-effect evaporator is specifically designed for the concentration and crystallization of sodium sulfate solutions. It employs forced circulation and mechanical vapor recompression technology, consuming ≤32kWh of electricity per ton of water, resulting in operating costs more than 45% lower than triple-effect evaporators. The system inhibits scaling through preheating and high-speed circulating evaporation, and, combined with an OSLO crystallizer, produces high-purity crystals of 0.4–0.8mm. Its core advantages include: heat recovery rate ≥90%, virtually no need for live steam and cooling water, support for automated operation and modular installation, and wide applicability to high-salt wastewater treatment in coal chemical and lithium battery industries, achieving energy conservation, emission reduction, and resource recovery.
