High - efficiency Industrial Wastewater Treatment Equipment: Technical Analysis and Application Guide for Wastewater Evaporators

2025-10-01

In the field of industrial wastewater treatment, wastewater evaporators, as the core technological equipment for dealing with high - salinity and high - COD wastewater, have become key equipment in highly polluting industries such as chemical engineering, pharmaceuticals, and food processing, thanks to their diverse process forms and remarkable environmental benefits. This equipment achieves the goals of wastewater volume reduction, resource utilization, and up - to - standard discharge through evaporation concentration and crystallization separation. I. Core Technologies and Process Forms Wastewater evaporators mainly include processes such as triple - effect evaporators, falling - film evaporation, forced - circulation evaporation, and low - temperature evaporation. Among them, the triple - effect evaporation system is widely used due to its high energy - efficiency. This system consists of three sets of series - connected evaporators, condensers, and salt separators. When treating wastewater with a salt content of 3.5% - 25% and a COD concentration of 2000 - 10000 ppm, the energy utilization rate can be increased to more than three times that of traditional single - effect evaporators.

Shell and Tube Condensers: A Comprehensive Analysis of the Principles and Applications of High-Efficiency Heat Exchange Equipment

2025-09-27

As a key device in the field of heat exchange, shell and tube condensers are widely used in industrial production. Their main function is to quickly transfer the heat in gases or vapors, causing the medium to condense into a liquid state. Its core structure consists of parallel tubes and an external shell, and the condensation process is achieved through the efficient heat transfer between the heat source and the cooling medium. I. Working Principle and Structural Design When the shell and tube condenser is in operation, high-temperature gases or vapors flow through the inside of the tubes, while the cooling medium (such as water or air) circulates in the shell. Heat is transferred through the tube wall to the cooling medium, causing the temperature of the heat source to drop and gradually liquefy. Its high efficiency is due to the use of high thermal conductivity materials such as copper and aluminum, which can accelerate heat transfer. In addition, some shell and tube condensers are equipped with cooling fins to increase the heat dissipation area, or use fans to enhance air convection, further optimizing the heat dissipation effect. Structurally, shell and tube condensers can be divided into three categories: water-cooled, air-cooled, and evaporative: 1. Water-cooled: It re...

2025-09-24

As an indispensable and highly efficient separation device in modern industry, the thin film evaporator has become a core equipment in fields such as chemistry, biopharmaceuticals, and food processing, thanks to its unique working principle and wide range of application scenarios. By precisely controlling temperature and vacuum degree, this device can achieve rapid concentration, desolvation, and purification of solutions. While improving production efficiency, it significantly preserves the active ingredients of materials, and is especially suitable for the processing needs of heat - sensitive and high - viscosity materials. I. Technical Principle and Structural Design The core working principle of the thin film evaporator is based on the synergistic effect of an ultra - thin liquid film (0.5 - 2mm) formed by the material on the heating surface and the vacuum system. During operation, the material enters the evaporation chamber from the top, and the rotating scraper system evenly distributes it on the heating surface, forming a continuously updated dynamic liquid film. Under vacuum decompression conditions, the boiling point of the solvent decreases. Combined with the heating of an external heat source (such as steam or heat - conducting oil), the solvent evaporates rapidly and ente...
