Bag filters for powders: which model to choose according to the load

When you need to install a bag filter for dust abatement within a company, there are a series of parameters to consider in order to evaluate the most suitable model according to specific needs. .

However, it should be noted that the use of sleeve dedusting devices ensures a series of advantages , such as:

  • Net reduction of emissions.
  • Reduced maintenance thanks to the efficient self-cleaning system using compressed air.
  • Reduced load losses in operation with minimum consumption of compressed air.
  • High durability of filter bags.

There is also the possibility of purchasing bag filters that comply with ATEX standards.

CleanMist® centrifugal filter to reduce oily mists

Cleanmist ® is the centrifugal filter for the abatement of oily mists produced by HFiltration .

This system is able to filter the air polluted by oily mists and coolants by conveying it into the filter through an inlet designed to block access to solid particles dispersed in the atmosphere.

From here, thanks to a conical diffuser, the particles of mists and vapors will be centrifuged at high speed and pushed towards special filter panels, passing through them the particles undergo the coalescence effect and are transformed into drained drops and subsequently collected externally by means of a special discharge pipe . What is collected can then be used again in the production cycle of the plant to which the centrifugal filter is associated.

The air that undergoes the purification process, once deprived of the polluting part, is pushed into the upper part of the filter where it will be treated by a final cartridge or, alternatively, sent to a final electrostatic filter (FEF), consequently depriving it of 99 % of impurities . In the latter case, the air will pass through an additional ionizing filter where particles up to 0.03 microns will be subjected to a strong electric charge and then subsequently attracted to special plates.

 

The benefits guaranteed by Cleanmist®

Thanks to the use of Cleanmist®, the filter for purifying the air from oily mists, you will find yourself in front of a system:

  • Easy to install
  • Effective
  • Little noisy
  • Which requires simple and reduced maintenance
  • Capable of recovering processing oil dispersed in the atmosphere

There will also be the possibility of making use of the HFiltration technical assistance to develop the most suitable solution, both in terms of scope and operation, but also for any problems and post-sales requests.

What is a centrifugal filter used for and what are its fields of application?

What is a centrifugal filter used for and what are its fields of application?

Centrifugal filters are designed to purify and break down the oily mists produced by industrial plants, precisely separating the air from the oil (or coolants), collecting the latter to re-enter it in the production cycle or to dispose of it.

The mists pass through the inlet of the filter passing a net positioned to avoid access to solid materials, and are then conveyed inside the plant itself. Here, through a conical diffuser , the particles are evenly distributed inside the filter and centrifuged at high speed to be pushed towards the external filter panels. Crossing them, the particles turn into droplets due to the coalescence effect , drained and conveyed to an exhaust pipe to be collected.

The purified air is then pushed into the upper part of the filter, where it will then be reintroduced into circulation after any treatment through a final cartridge or an electrostatic filter.

Application of centrifugal filters
  • Centrifugal filters that exploit the coalescence principle for the recovery of the oils present in oil mists can be
  • applied for the suction of:
  • Machine tools
  • Lathes
  • Metal washing machines
  • Drilling
  • Milling
  • Boring machines
  • Machining centers.

The success of this type of centrifugal filter lies in the ease of installation , in the high efficiency guaranteed, in the low noise level , in the reduced maintenance and in the low consumption necessary for its operation. Furthermore, thanks to the coalescence principle, the oily particles dispersed in the atmosphere will be recovered, collected and, consequently, reintroduced into the production cycle of the plant.

The CLEANMIST® Solution for Oil Mist Centrifugal Filters

HFiltration_Mistcollector-Cleanmist-range.jpg
The CLEANMIST® range includes a vast series of oil mist centrifugal filters. Air polluted by oil mist or liquid coolant is channelled into the centrifugal filter, going through the intake with mesh to prevent solid materials from being suctioned.
A cone-shaped diffuser ensures that the mist particles and vapours are evenly distributed inside the impeller, where they are rapidly spun and pushed towards the filtering panels. As they go through the panels, the particles undergo coalescence, transforming into droplets, which are then drained to the outside through a specific drain pipe. Purified air is thus channelled towards the upper part of the centrifugal filter, where, if necessary, it is treated with a final cartridge or with a final electrostatic filter (FEF).

CLEANMIST® with Final Electrostatic Filter

CLEANMIST-con-Filtro-Elettrostatico-Finale.jpg

It operates based on the principle of ionisation of polluting particles. The air coming out of the CleanMist® filter passes through an “ionising” section where particles up to 0.03 µm (micron) receive a strong electrical charge. The air flow goes through a second “collector” section, made of plates with the opposite electrical charge. Ionised contaminant particles are thereby drawn to the plates and stick to them. The treated air is delivered back into the environment with 99% of the impurities removed.

The Idrodust Compact® hydrodynamic filter Solution for a hydrodynamic dust, vapour and gas suppressor

Filtro-idrodinamico-IDRODUST-COMPACT-ID115.jpg

The Idrodust Compact® hydrodynamic filter is a hydrodynamic dust, vapour and gas suppressor that uses the effect of micromixing the air being treated with water.

The air to be treated enters the filter by passing through an expansion chamber which significantly slows down the flow which promotes the precipitation of coarse polluting particles; the air flow then passes through the venturi duct, dragging part of the water present in the filter. The centrifugation process, which humidifies the polluted air and retains the polluting particles, takes place in the venturi duct. Before the clean air is ejected, it passes through a droplet separator, depositing the particles of water trapped in the air flow onto this separator.

It has no parts that are subject to wear or clogging, which helps reduce maintenance.

  • Applications :
  • Sandblasting
  • Mechanical processing
  • Water soluble gas flows
  • Metal glazing
  • Generic dust

  • Efficiency: Emissions ≤ 10 mg/Nm³*
    *Other emissions obtainable on request
  • Extremely contained installation, use and maintenance costs
  • Multiple filter inspection access points
  • No risk of fire thanks to the presence of water

  • IDRODUST COMPACT® hydrodynamic filter with Sludge dredge

Filtro-idrodinamico-IDRODUST-COMPACT-con-Dragafanghi.jpg

The Idrodust Compact® hydrodynamic filter with Sludge dredge operation, similar to the standard version, differs in how sludge is automatically drained from the sedimentation tank. Scrapers collect the dust/sludge that settles at the bottom of the tank and it is transported mechanically to the outlet for disposal. The Sludge dredge prevents having to stop the machine to remove sludge, considerably reducing general management costs.

 

  • IDRODUST COMPACT® hydrodynamic filter with Venturi Pump

HFiltration_Hydrodynamic-Filter-Idrodust-Compact-Pump-2000x1000px.jpg

The Venturi Pump system consists of a 250 litre water tank connected to the IDRODUST COMPACT® filter tank. The tank is equipped with a pump that pushes the fluid into a rigid PVC pipe up to the nozzles inserted in the venturi pipe. The flow of air being treated is thus washed before entering the filter. A level switch to protect the pump is installed on the tank, which switches off the motor if the level of water in the tank drops below a safety threshold.
