Application of MVR Roots blower in environmental protection field
MVR (Mechanical Vapor Reconsideration) Roots blower, more precisely MVR Roots steam compressor, is a special purpose compressor developed based on the basic principles of Roots blower, commonly used for compressing water vapor in MVR evaporation systems. The following is a detailed analysis of the MVR Roots blower:
 
1、 Working principle
The MVR Roots blower (steam compressor) separates the inlet and outlet through the "engagement" of a pair of rotors. The rotor is driven by a pair of synchronous gears and moves in the opposite direction, pushing the secondary steam sucked into the MVR system evaporation chamber from the suction port to the exhaust port. When the secondary steam reaches the exhaust port, it is pressurized due to the back pressure on the heating side of the heat exchanger, thus completing the transportation and compression of the secondary steam.
 
2、 Structural composition
The MVR Roots blower mainly consists of the following components:
 
1. Host: Core component, including rotor and related sealing structure.
2. Motor: Provides power source to drive the rotor to rotate.
3. Inlet and outlet bellows compensator: used to compensate for pipeline deformation caused by temperature and pressure changes.
4. Inlet sealed water connection pipe and outlet connection pipe (T-shaped air outlet): used for connecting the inlet and outlet of steam respectively.
5. Pressure gauge: displays the pressure status of steam.
6. Transmission device: including gearbox, etc., used to transmit the power of the motor to the rotor.
7. Anchor bolts (or shock absorbers): used for fixing and damping.
8. Lubricating oil: Ensure lubrication and cooling of components such as rotors and gears.
3、 Performance characteristics
1. Energy saving: MVR Roots blower achieves steam reuse by compressing secondary steam, greatly improving energy utilization efficiency and reducing energy consumption.
2. Reliable operation: Made with advanced technology and materials, it can operate stably in high temperature and high pressure environments, ensuring the normal operation of production equipment.
3. Easy maintenance: The structure is relatively simple, and the components are easy to disassemble and replace, reducing maintenance costs.
4. Environmental protection and emission reduction: By reusing steam, the emission of waste gas is reduced, which meets the requirements of energy conservation and emission reduction.
4、 Application Fields
MVR Roots blowers are mainly used in MVR evaporation systems for compressing and transporting secondary steam. MVR evaporation systems are widely used in industries such as chemical, pharmaceutical, food, and environmental protection to treat materials such as wastewater and waste liquid, achieving the goals of energy conservation, consumption reduction, and environmental protection.
 
5、 Maintenance and upkeep
In order to ensure the normal operation and extend the service life of MVR Roots blowers, regular maintenance and upkeep are necessary. Here are some common maintenance and upkeep measures:
 
1. Regular inspection: Regularly check the operation status of the fan, including vibration, noise, temperature and other indicators.
2. Cleaning and maintenance: Regularly clean the inlet, outlet, and internal components of the fan to avoid dust and debris from affecting the normal operation of the fan.
3. Lubrication and maintenance: Regularly check the oil level and quality of the lubricating oil, replenish or replace the lubricating oil in a timely manner, and ensure good lubrication between various components.
4. Tightening components: Regularly check the fastening condition of each component, and if there is any looseness, tighten it in a timely manner.
5. Troubleshooting: If the fan malfunctions, timely troubleshooting and maintenance should be carried out to avoid the expansion of the fault.
In summary, MVR Roots blower is an energy-saving, reliable, and easy to maintain compressor equipment. It plays an important role in MVR evaporation systems and provides strong support for industries such as chemical, pharmaceutical, food, and environmental protection.
