MVR Evaporative System

　MVR Evaporative System

ModMVR Evaporative System

Traditional single- and multi-effect evaporators rely on boiler-generated fresh steam as the heating source. The secondary steam produced during evaporation is condensed by cooling water, causing heat loss and additional cooling water consumption.

MVR Working Principle: The MVR evaporator compresses secondary steam through a st compressor to increase its pressure, temperature, and enthalpy. The compressed steam is reused as the heating medium, replacing fresh steam and enabling an efficient heat cycle with minimal electrical energy consumption. As an open heat pump system, the steam compressor transfers secondary steam heat rather than generating additional evaporation heat.

SHANGCHEN standard skid-mounted ModMVR evaporative equipment integrates HEMVR heat pump technology with evaporation, crystallization, separation, and           intelligent automation systems. By utilizing electrical energy to recover and reuse secondary steam, the system significantly improves energy efficiency while enabling material concentration and zero liquid discharge (ZLD) treatment for the brine.

Applications

Widely applied in the concentration and crystallization of brine and Elevated-COD effluent streams from chemical, electroplating, semiconductor, metallurgy, printing and dyeing, pharmaceutical, new energy, machining, environmental protection, hazardous waste, and other industries.

Main application: electroplating effluent, cutting effluent, emulsion effluent, fermentation effluent, cleaning effluent, battery effluent, landfill leachate and RO              membrane concentrate, etc.

Based on ModMVR Evaporative System, SHANGCHEN energy-saving EcoMVR evaporation system adopts the latest energy-saving steam compressor to further cut operating power consumption for energy saving and cost reduction.

Product Features

1. Low Vibration and Noise

Energy-efficient steam compressors ensure quiet, low-vibration operation.

2. Energy Saving

The SHANGCHEN EcoMVR Evaporator features a high-efficiency permanent magnet motor and 3D-flow impeller, reducing energy consumption by over 25% compared with conventional high-speed centrifugal MVR systems and over 50% compared with Roots-type MVR systems.

Product Model

UltraMVR Evaporative System

Conventional MVR evaporators typically have a maximum temperature rise of 25°C, limiting their ability to concentrate and crystallize high-boiling-point, high-concentration solutions, such as chemical waste liquids, evaporation mother liquor, chloride and nitrate solutions, phosphates, acids, and alkalis.

The SHANGCHEN UltraMVR Evaporative System bases on the ModMVR Evaporative System, using proprietary ultra-high temperature-rise MVR technology to raise secondary steam temperature to 60°C for cost-effective concentration and crystallization of high-boiling materials.

Product Features

1. Designed for Complex Effluent

Suitable for concentrating and crystallizing high-boiling materials, including calcium chloride, lithium chloride, sodium nitrate, brine and high-COD effluent, evaporation mother liquor, landfill leachate, and electroplating effluent.

2. Rise up to 60°C

The SHANGCHEN UltraMVR Evaporative System achieves a secondary steam temperature rise of up to 60°C and a maximum pressure ratio of 25:1, significantly exceeding conventional MVR systems. Enables efficient concentration and crystallization of high-concentration, high-boiling materials while reducing the risk of low evaporation rates and compressor surge.

3. Low Operating Costs

MVR energy-saving technology reduces operating costs to as low as RMB 50–80 per ton of water treated, compared with RMB 200–500 for conventional treatment equipment, according to the stated cost estimates.

4. Flexible Material Selection

Stainless steel, titanium, and other materials can be selected based on the feed characteristics, balancing corrosion resistance, service life, and cost-effectiveness.
