EcoTurbo

Introduction and Purpose

The EcoTurbo device for metallic cages of sleeve filters based on impulse air cleaning technology aims to simultaneously improve sustainability aspects:

  • The energy consumption of the dust collector
  • The efficiency of filtration and cleaning of the sleeve filter
  • The lifespan of the installed devices.

Inlet and Outlet Air Flow

Inlet and Outlet Air Flow

One of the drawbacks sometimes attributed to the traditional use of the venturi tube in sleeve filters is that, while favoring cleaning operations by improving the dust discharge phase, it limits the air outlet under operating conditions compared to the useful section of the sleeve filter diameter. This does not occur with EcoTurbo, a high-performance venturi tube both during the cleaning phase and in normal suction operation.


Utilization of the Entire Filtration Surface

Utilization of the Entire Filtration Surface

The EcoTurbo device is mounted elevated on the flanged collar of the cage. It effectively extends inward into the basket. In contrast to traditional venturis riveted with internal development, EcoTurbo utilizes the space properly created between the collar and venturi to achieve the patented dual effect of enhancing the shot with indirect air input and obtaining flows in the area immediately adjacent to the device, otherwise not affected by the shot's effect.


Sustainability and Durability

Sustainability and Durability

The EcoTurbo device is designed for maximum durability and sustainability. It can be riveted to the support collar or bolted and easily removed for reuse on a new support. It is also made of recyclable aluminum and is safe even in environments with combustible dust, especially when associated with the Ecoatex cataforesis cage.


Enhanced Shock Wave

Enhanced Shock Wave

The design of EcoTurbo has particularly emphasized those constructive features capable of enhancing the effect of the shock wave from the compressor shot, with the declared goal of being able to discharge a larger amount of dust from the sleeve at the same pressure offered by the shot. EcoTurbo practically amplifies the peak positive pressure and depression of the shock wave by percentages up to 50%.


Dust Cake Removal

Dust Cake Removal

The combined effect of enhancing the peak pressure and controlling a contained shot time allows slowing down the cleaning cycles operated by the compressor, simultaneously lowering the ∆P present on average in the system with substantial advantages in energy recovery, even on the collector fan.


Advantages

Advantages

  • Reduced compressed air and energy consumption for valves and compressor
  • Reduced fan energy consumption
  • Increased air outlet flow compared to traditional venturis
  • Increased sleeve filter lifespan


Characterizing Elements of the EcoTurbo System

The Venturi Tube

The Venturi Tube

The EcoTurbo venturi tube is only superficially similar to other venturis. In fact, the ratio between the diameters of the various sections, lengths, and radii of curvature has been designed using CFD analysis techniques and subsequently experimentally validated. The device is patented. An important element of the patent lies in the ability to recover space to increase the size of the central throat outside the cage space, avoiding closing the air outlet section too much (section lost due to maximum values of 4% compared to available space). Therefore, the goal is to maximize the available space inside the cage for device placement. The venturi tube marked with the CleanAir logo is marked with the recyclable aluminum symbol and production lot information.

Available Models

Available Models

The unique shape of EcoTurbo has been studied in three different models to adapt to tubular plates with diameters from 120 mm up to 170 mm and respective cages.

The Tag

The Tag

An appropriate seat on the upper part allows the application of digital tags and beacons, such as the EcoSmart tag, the CleanAir Europe basket EAM identification solution in NFC technology.

In the following charts, a comparison is made, using CFD techniques, of the values of the peak pressure detected for the EcoTurbo venturi compared to the traditionally used Venturi. The simulation was then experimentally validated with a field test.

Research with the Polytechnic of Milan – CFD Analysis and Experimental Verification

The design of the profile of the new EcoTurbo venturi, aimed at increasing the performance of the shot management in particular, is the result of the company's collaboration with the Department of Civil and Environmental Engineering and the Department of Mechanical Measurements of the Polytechnic of Milan. The analyses, especially carried out with CFD techniques, lasted for two years until the presentation of the device on the market. The analyses concluded with experimental validation confirming the validity of the CFD techniques used to study the peak pressure field of the shot.


European Patent

EcoTurbo devices are patented with European patent application No.230060/EP and two Italian prior rights numbers 102023000002421 of 13.02.23 and number 102023000015945 of 28.7.23. In particular, the patent emphasizes the innovative function of:

  • The slots on the device to increase the flow of indirect air sucked during cleaning
  • Ratios between the different throats of the venturi tube and the internal diameter of the support collar (and therefore of the tubular plate)
  • The maximum percentage of space (internal light) subtracted from the useful section of the sleeve during emission.


Return on Investment

Return on Investment

In the face of a slight initial cost increase due to the enlargement of the device, once installed, EcoTurbo provides a very rapid return on investment with significant savings over time, starting from the first year compared to the traditional solution. Substantial reductions in energy consumption of the compressor and valves, compressed air savings, and reduced power used by the fan characterize the solution.

FAQ – Frequently Asked Questions EcoTurbo features

To what extent are peak pressure of the shock wave and lower energy consumption connected?

According to various academic studies, the best shock wave connected to a short cleaning shot duration is capable of discharging more dust on average with each shot, thus reducing the cleaning frequency, as it will take more time to reload the dust with the same ∆P.

Can I calculate the energy savings I will have in advance?

Energy savings depend on multiple factors, including, just to name a few, plant settings, filtration area, dust type, basket length, shot power, and air flow. Therefore, a precise calculation of savings is possible only after installation. In principle, savings of 10% to 30% are expected.

Can I increase the treated air flow?

One of the advantages of EcoTurbo is precisely not to subtract light to the emission into the atmosphere during normal operation and to favor a longer cleaning cycle.

Does installing EcoTurbo require special skills?

No special instructions are needed to install EcoTurbo, which only requires a flanged surface of the collar and the presence of holes to be made at the supports of the device with a simple drill. Riveting is then recommended.

Can I install EcoTurbo in my old system?

In most cases where the cage has a flanged collar, it is possible to install EcoTurbo above the existing cage.

How far from the device should I place the shot pipe?

Generally, at distances not exceeding 10 cm from the upper flanged plane of EcoTurbo; specific exceptions may depend on the shape of the shot nozzle.

Can I use EcoTurbo in ATEX applications?

EcoTurbo is made of conductive material, so it is suitable for use in explosive dust environments. To reduce jumps in the triboelectric scale, it is recommended to use it with EcoAtex cages in cataforesis.

At what nominal pressures of the Jet-Pulse system tank does EcoTurbo work?

Ecoturbo has been tested with system tank pressures from 3 to 6 bar.

Can I reuse EcoTurbo for other baskets in case of replacements?

If the device is still in good condition, it will be possible to easily disassemble and reassemble it on the new basket, favoring greater durability and sustainability.

Can I record data related to the cage and sleeve in the EcoTurbo tag?

The EcoTurbo device is designed to accommodate a digital beacon in a suitable seat on the flange. Through the CleanAir Europe srl EcoSmart cage platform, information can be stored and made available to the user not only about the venturi tube but also about the installed filter sleeve and basket, documenting over time any replacements that have occurred.
