产品概述

MVR（Mechanical Vapor Recompression，机械蒸汽再压缩）蒸发器是当今国际领先的高效节能蒸发浓缩设备。它利用压缩机对蒸发过程中产生的二次蒸汽进行压缩，提高其温度和压力后重新作为加热热源循环利用，实现蒸汽潜热的循环再生，大幅降低能耗与运行成本，是传统多效蒸发器的理想替代方案。

工作原理

物料进入蒸发器加热浓缩，产生的二次蒸汽经蒸汽压缩机绝热压缩后，温度与压力显著提升，再送入加热器作为热源加热物料，蒸汽释放潜热后冷凝成水排出。整个系统仅需少量启动蒸汽和电能驱动，即可连续稳定运行，实现 "一度电回收数十倍蒸汽潜热" 的节能效果。

核心优势

• 极致节能：无需锅炉供汽，吨水耗电量仅 20~60kW・h，较传统蒸发器节约运行成本 50%~70%

MVR Evaporator — Product Introduction (English)

Overview

The MVR (Mechanical Vapor Recompression) Evaporator is a world-leading, energy-efficient evaporation and concentration system. It compresses the secondary vapor generated during evaporation with a steam compressor, raising its temperature and pressure so it can be reused as the heating source. This recovers the latent heat of vaporization, dramatically cutting energy consumption and operating costs — the ideal replacement for traditional multi-effect evaporators.

Working Principle

The feed liquid is heated and concentrated in the evaporator. The secondary vapor is adiabatically compressed by the vapor compressor, raising its temperature and pressure before being fed back into the heater to heat the feed. After releasing its latent heat, the vapor condenses into water and is discharged. The system runs continuously and steadily with only minimal start-up steam and electric power — recovering dozens of times the latent heat for each unit of electricity consumed.

Key Advantages

• Ultimate energy saving: No boiler steam required; power consumption of only 20–60 kW·h per ton of water evaporated; operating costs reduced by 50%–70% vs. traditional evaporators

• Low carbon & environmental: Condensate and secondary vapor fully recovered, achieving near-zero liquid discharge

• Intelligent control: Fully automatic PLC control with real-time monitoring of temperature, pressure, level and concentration

• Low-temperature concentration: Ideal for heat-sensitive materials, preserving active ingredients and product quality

• Stable operation: Core components in 304 / 316L / Titanium / Hastelloy for demanding conditions

Applications

• Industrial wastewater treatment (high-salinity, chemical, electroplating)

• Pharmaceutical concentration (herbal extracts, API concentration)

• Food & beverage (juice, dairy, condiment concentration)

• Chemical & salt industry (NaCl, Na₂SO₄ crystallization)

• Biological fermentation & zero-discharge projects
