Introduction to Industrial Water Evaporator Systems
Industrial water evaporation technology, namely mechanical vapor recompression technology (Mechanical Vapor Recompression), is an energy-saving technology that reuses the energy of secondary steam generated by itself, thereby reducing the demand for external energy. The industrial water evaporator recompresses the evaporated secondary steam through a mechanical compressor or fan to increase its enthalpy value. The secondary steam with increased enthalpy value is again sent to the heating chamber as a heat source to heat the feed. After releasing the heat Condensate into water and drain. The vaporized and concentrated materials are finally discharged from the system as products.
Industrial water evaporator system components
The industrial water evaporation system consists of evaporators, separators, compressors, vacuum pumps, circulation pumps, operating platforms, electrical instrument control cabinets, valves, pipelines and other components, forming a complete working system.
Industrial water evaporator system features
Industrial water evaporators only require a small amount of raw steam, which greatly reduces operating costs and environmental pollution. The system has no waste heat steam emissions and has significant energy saving effect.
Using a compressor to provide heat source, compared with traditional evaporators, the temperature difference is smaller, achieving gentle evaporation, significantly improving product quality and reducing scaling.
The system structure and process are simple, fully automatic operation, continuous operation, safe and reliable.
The equipment has a built-in CIP cleaning pipeline, which can realize on-site cleaning. The entire equipment is easy to operate, has no cleaning dead corners, and has significant energy saving effect.
The materials suitable for single-effect and multi-effect evaporators are technically completely replaceable and have better environmental protection and energy-saving characteristics.
Industrial water evaporator system application areas
Industrial water evaporators are widely used in many industrial fields, especially in industries that require efficient and energy-saving evaporation, crystallization and concentration processes. Specific application areas include:
Chemical industry: In the chemical production process, solutions are concentrated or pure solvents are extracted. Industrial water evaporator technology can effectively complete these processes while significantly reducing energy consumption.
New energy industry: In processes such as battery manufacturing, evaporation technology is used to recover or purify substances.
Food industry: used to concentrate liquid foods such as juices and syrups to increase concentration while retaining flavor.
Coal chemical industry: Effective treatment and recycling of wastewater containing various chemical substances produced by coal chemical industry.
Electric power industry: For example, treatment of desulfurization wastewater from power plants can help reduce costs and improve water resource recycling rates.
Electroplating industry: purify and recycle wastewater containing heavy metals and other harmful substances produced in the electroplating process.Environmental
Protection field: Provide effective solutions to environmental problems such as high-salt wastewater treatment and landfill leachate treatment, reduce pollutant emissions, and meet environmental protection standards.
Technical principle of
Technical principle of high salt water discharge MVR Evaporator: in working process of high salt water MVR evaporator, the softener is first heated in the pre-stressed heat to near the boiling point, and then applied to the body of the evaporator. Here the softener is heated until boiled to produce steam; then, water steam comes into the liquid separator to separate out pure vapor and concentrated liquid. Pure steam is inserted into the steam compressor, where temperature and pressure increase after pressing, and the evaporator continues to be used to deflate as a source of heat. While the concentrate is discharged from the system for subsequent treatment or recovery.
