Product category: Filter technologies (flue gas and electrostatic)

Electrofilters

Electrostatic precipitators are designed for the removal, within the required limits, of the dust carried by gases generated by fusion or combustion processes. The precipitator is constituted by collecting plates and emitting electrodes. Area Impianti has refined its technological expertise in this sector, optimising it to meet the needs of the various specific applications.

Having started out with consolidated technology, Area Impianti has gone on to overhaul the concept of the electrofilter by applying innovations deriving from its experience in the field and its partnerships with universities.

Specifically, it has conducted research and development on:

  • special-geometry electrodes for superior distribution and increased intensity of the electrical field
  • an innovative pre-heating and flushing system for the insulators to increase reliability and efficiency over time
 To design our electrofilters, our Technical Department utilises state-of-the-art software that makes it possible to:

  •  integrate solid/fluid dynamic modelling with electro-capturing simulations, optimising the performance levels constantly update the algorithms, comparing the simulations against the results obtained in the field

Bag filters

Bag filters are Area Impianti’s most well-established product. The experience accumulated over the years across various applications has enabled the company to develop solutions that make it possible to improve the efficiency and reliability of the bags, reducing the frequency and associated cost of maintenance operations to exceptionally low levels.

 The ALL IN ONE range combines optimised dimensions with clear advantages in terms of installation time and cost. The (round or oval-shaped) bags are always positioned vertically, with positive consequences in terms of durability, the efficiency of the cleaning process and the level of safety in the event of maintenance.

 The chosen filtering medium is always appropriate for the specific nature of the flue gas in question, making it possible to guarantee dust levels even below 1 mg/Nm3.

Area Impianti’s filters can be sub-divided into cells, ensuring easy access to all of the components subject to maintenance, thus reducing downtime.

Even when featuring excludable cells, the filters continue to provide efficient ON-LINE cleaning with compressed air: an electronic sequencer manages the blowing cycle of the bags, keeping all of the cells open, thereby fully exploiting the available filtering surface area.

The PPOD cleaning system makes it possible to calibrate the pulse pressure for the cleaning of the bags to match the actual level of dirt; this allows users to boost effectiveness, save energy and enhance the efficiency of the reagent deposited on the bags.

Gas conditioning

Temperature management has a crucial role to play in flue gas treatment chains.
By leveraging its know-how, Area Impianti has the capacity to optimise in energy terms the cooling and post-reheating phases of the flue gas, enabling at the same time the recovery of energy from the flue gas.

The following technologies are regularly deployed:

  •  Cooling through air dilution
  • Water quenching
  • Flue gas/air or flue gas/flue gas heat exchange
  • Flue gas/water or oil heat exchange
Water cooling takes place in quenching towers, where water is sprayed and then evaporates completely. Spillback and twin-fluid nozzles may be used. The quenchers may have ascending or descending flow. The water used may be process water, with consequent elimination of the liquid discharge of the plant.
The heat exchangers may be tubes or plates. Plates are recommended in the event of high dust levels.

These devices can also be used for flue gas/flue gas heat recovery, pre-heating of condensation, ORC, etc…
Thanks to Area Impianti’s industry expertise, certain elements in the construction of these cooling systems allow them also to be used as reactors. Due to specific, reliable, automated internal cleaning systems (chain scrapers), the injecting of the reagent can take place upstream of the cooler, the volume of which can therefore be used for reactions and adsorptions.

In addition, the special design of the heat exchangers eliminates the risk of the wall temperature nearing the acid dew-point. Partial recirculation of the outgoing warm air makes it possible to adjust the temperature of the incoming air.
