Any pulse-jet dust collector can be retrofitted with a VEnTO controller to extend bag life and optimize compressed air consumption.
One advantage of the VEnTO controller is its ability to extend the life of membrane bags. Typical expected lifetime is greater than 4 years, and often in excess of 6 years.
The latest emissions regulations have reduced the maximum allowable emission limits to such a degree that many existing precipitators cannot achieve compliance. In such cases, it becomes necessary to provide costly additional fields, or to install cost-effective, high efficiency, retrofit fabric filter technology in the existing casing.
In many cases, the fabric filter portion of the retrofit can be assembled and tested on the ground. The ESP is removed in one piece and the new fabric filter section is lifted in one piece, reducing plant down time. In most cases the retrofit will require 1-2 weeks for the tie-in work.
Our technical department is specialized in the analysis, design and supply of custom engineered fabric filter retrofit technologies and in the supply, erection and commissioning of the new system, including performance guarantees.
Even the analysis of the gas moving system under the new operating parameters can be trusted to the competence of our fan specialists.
Filtering equipment can be selected with various bag lengths, typically from 4 to 8 meters (12 to 24 feet).
Due to the unique experience of BoldEco Environment and with the implemenation of new technologies, such as the newly developed Vento Controller, CFD Technology and ePTFE membrane filter media, one can expect 4-6 years of bag life under normal use.
BoldEco offers the following fabric filter system solutions for conversions of ESPs in dedusting applications:
The EcoVent medium-pressure PJFF design is implemented in applications with powdery or easy to release dust and medium to low dust loads. EcoVent medium-pressure PJFFs are the industry standard for bags greater than 6m (18 feet) in length. Medium-pressure PJFFs utilize pressures between 1-3 bar (15-45 psig).
With the addition of a VEnTo (Variable Energy-Timing Optimized) pulsejet controller, the any EcoVent PJFF can be converted to a hybrid-pressure design. The main advantage of a hybrid design is that the dust collector will automatically respond to changing dust collector conditions to provide the optimum pulsing pressure, thus resulting in a design that provides the best balance between performance and bag life. Hybrid-pressure PJFFs utilize pressures between 1-6 bar (15-90 psig).
