Evaporation of liquid in a closed circuit Process steam (evaporation) resulting from industrial processes is removed by means of a radial fan (steam compressor) to a higher temperature, and therefore energy level, and then returned to the circuit as fresh heating steam. The energy of the steam is not lost; it is only necessary to additionally supply the energy required to increase the temperature. Since energy costs have risen sharply in recent decades, everyone is looking to reduce fossil fuel consumption and emissions. carbon dioxide, as well as reduce the still high steam consumption in these processes.

These goals can be achieved through mechanical vapor recompression, since lately Refinement of this process has turned it into an economical and reliable technology used in processes such as evaporation, distillation, crystallization and drying.

The closed process allows temperature-sensitive liquids, such as milk at approximately 60°C or even blood plasma at 35°C, to be evaporated under high vacuum. At the same time, valuable components of the final product are preserved (for example powdered milk) and the quality increases, and with it the cost of the product.

Applications
At the beginning of its development, mechanical vapor compression was used mainly in the dairy industry. Subsequently the process found wide application and in other areas, such as processing and/or production:

Applications

The Piller steam compressor is a high-tech equipment that is highly standardized. No other product from Piller Industrieventilatoren GmbH has so many design innovations. Thanks to standardization, the basis has been laid for cost-effective solutions that can be implemented very quickly.

To ensure long-term reliability and reduce vibration to almost zero, Piller has developed a bearing unit that is unique in its kind. support system Piller-Quetschöldämpfung, for which she subsequently filed a patent. This bearing assembly, which is used with both rolling and plain bearings, is designed to operate in supercritical conditions.

This means that the stiffness of the bearings is no longer a significant factor in the calculations, and therefore the unwanted and critical dependence of the rotor-wheel system on vibration that destroys the bearings can be significantly reduced. Since the rigidity of the bearings is now of secondary importance, the bearing assemblies are precisely designed for greater reliability in response to the loads encountered (load factors) and peripheral speeds.

Typically, a smaller bearing assembly with a higher permissible speed can be used in this way. Detailed information See our brochure “Fans in the Critical Range”. Shaft seal Depending on operating conditions, apply various principles shaft seals.

In general, they differ in the following operating conditions:

  • The process takes place in a high vacuum of 50 mbar< Pabs, < 200 мбар
  • The process occurs when excess pressure 1 bar< Pabs
  • The process takes place in high vacuum without a sealing medium

Control devices

The basic kit of the Piller steam compressor includes an electronic control device. Touch sensors are located in the main terminal box and record the following parameters

  • Case temperature
  • Bearing temperature
  • Fan shaft vibration level
  • Rotational speed
  • Oil temperature
  • Oil level
  • Oil volumetric flow
  • Oil pressure
  • Condensation level at the bottom of the housing

Evaporation and distillation processes are used in a variety of industrial applications. Be it chemical food industry or water treatment - the most effective way To reduce energy costs is to use mechanical vapor recompression fans.

TLT-Turbo GmbH has developed a range of steam compressors that meet and exceed all modern standards, as do many of our products.

MVR Turbo Fan

We reduce operating costs.

A number of factors play a critical role in accounting for and amount of potential savings:

1. Best selection and design of the fan

The correct selection of a fan for specific requirements is guaranteed thanks to the wide range of TLT-Turbo sizes. This is important to achieve maximum efficiency.

2. Proper temperature rise

An increase in temperature up to 9°C is quite possible with TLT-Turbo steam compressors. Values ​​higher are possible depending on the operating point. What is important is that steam compressors can be installed in cascade and the temperature increased even higher. It should be remembered that the higher the pressure and temperature, the more the efficiency of the steam compressor can drop, so it makes sense to install another steam compressor and thereby reduce energy consumption. This and other factors are subject to discussion on a case-by-case basis.

3. Use of energy-efficient motors and emergency situations

If there is such a requirement, we can offer our fans with optimally matched motors and variable speed drives from well-established manufacturers.

4. Long service life at low running costs

TLT-Turbo GmbH has something special in store for you in terms of service life and operating costs. All mechanical vapor recompression fans are equipped with modern maintenance-free hybrid ceramic bearings. These high-tech bearings, which until now have been mainly used in wind turbines and machine tools, have a lifetime lubricant supply and have a service life longer than standard bearings. Since no lubrication is required, regular oil changes are completely eliminated.

Made to order for your project, the way you want it

All fans are produced and completed various materials, for example, impellers made of duplex or super-duplex stainless steel, or even titanium - and this is a design created specifically for your application.
