Plate MVR Evaporator

1. Plate MVR Evaporator Structure and Principle:

The core of the plate MVR evaporator is the use of a high-efficiency steam compressor to compress the secondary steam generated during the evaporation process, increasing its pressure and temperature, thus increasing its enthalpy. This high-temperature, high-pressure steam is then fed back into the heater as a heat source to heat the raw liquid. This recycling of secondary steam significantly reduces the demand for external energy, achieving rapid energy utilization.

2. Plate MVR Evaporator Structure:

Evaporator: The main equipment, including the heater, separator, and circulating pump, responsible for heating, evaporating, and concentrating the material.

Compressor System: The core equipment, providing the evaporation heat source by compressing the secondary steam and increasing its enthalpy.

Preheater: Used for waste heat utilization and increasing the feed temperature, further recovering heat.

Vacuum System: Maintains the vacuum level of the entire system, extracting some non-condensable gases and gases introduced by the solution to achieve a stable evaporation state.

Control System: Enables automatic evaporation, cleaning, and shutdown operations, with automatic alarms, automatic system protection against damage, and maintenance of system dynamic balance.

3. Key Selection Points for Plate-Type MVR Evaporators

Material Characteristics: Clearly define the wastewater's pH value, salt type and concentration, COD, and other parameters to select appropriate materials and equipment types. For example, high-salt wastewater (containing chloride ions) requires corrosion-resistant materials such as titanium alloy or 2205 duplex stainless steel.

Treatment Capacity and Efficiency: Select equipment specifications based on the daily treatment capacity to ensure a suitable evaporation capacity. For medium to large-scale treatment (≥10 tons/day), the energy-saving advantages of MVR evaporators are significant.

Comprehensive Economic Assessment: Although the initial investment in MVR equipment is higher, the operating cost is low, and the payback period is typically 6-12 months. Its energy-saving advantages are evident in long-term operation.

Manufacturer Qualifications: Choose manufacturers with ISO certification and proven track records.

4. Advantages of Plate-Type MVR Evaporators:

Significant Energy Saving: Compared to traditional evaporators, MVR evaporators can save 50%-80% of energy consumption.

Small Footprint: The compact size allows for the economical use of special alloy plates (such as titanium), saving floor space.

Modular Design: Facilitates integration with compressors, separators, etc., into standardized modules, reducing transportation and installation costs.

Intelligent Control: Combining the rapid response characteristics of welded plate evaporators, flow rate and temperature can be adjusted in real time via PLC, improving the automation level of the modular system.
