Scrubber adalah sistem filtrasi, juga dikenal sebagai scrubbing towers untuk menghilangkan senyawa organik yang mudah menguap, apa itu dan bagaimana cara kerjanya? Pada artikel ini kami akan memberikan informasi dasar untuk lebih memahami mekanisme yang memungkinkan pengurangan VOC dan pemurnian udara.

Scrubbing towers digunakan untuk mengurangi dan menghilangkan debu dan polutan yang ada di aliran udara. Sistem ini biasanya dimasukkan dalam konteks tertentu yang bertujuan untuk menyaring dan memurnikan udara dari asap, uap, dan debu yang berbeda asalnya. Penggunaan sistem penyaringan khusus ini merupakan persyaratan wajib, terutama untuk menghilangkan polutan sisa yang mungkin ada dan memiliki lingkungan yang sehat dan aman.

Bagaimana cara kerja scrubber?

Scrubber dapat mengurangi senyawa organik volatil (VOC) dan konsentrasi debu yang ada dalam aliran gas. Ini digunakan bila ada zat yang akan dihilangkan yang mampu bereaksi dengan adanya air karena sebenarnya pengurangan terjadi melalui dampak antara washing liquid yang disemprotkan dan polutan.

Scrubbing towers sebenarnya terdiri dari badan silinder di mana proses pemurnian dan netralisasi zat berbahaya terjadi, asalkan ini adalah bahan kimia organik atau anorganik yang larut dalam air.

Asap yang akan diolah masuk ke washing tower, atau scrubbing column, melalui akses yang ditempatkan di bagian bawah menara. Saat naik, asap terus disemprot dengan washing liquid nebulisasi yang diambil dari tangki penahanan oleh pompa resirkulasi. Pada akhir pengolahan, separator akan menangkap tetesan-tetesan yang telah menjebak polutan, sedangkan asap yang telah dimurnikan akan dilepaskan ke lingkungan dengan keluar melalui lubang khusus yang terletak di bagian atas plant.

Wet abatement systems dapat terdiri dari beberapa tahap pencucian, bahkan dengan jenis operasi yang berbeda, tergantung pada polutan yang akan diolah.

Apa hasil yang diperoleh setelah penggunaan sistem penyaringan udara ini? Polutan, yaitu senyawa organik yang mudah menguap, akan berkurang, memastikan keuntungan yang sangat besar bagi lingkungan, yang akan lebih bersih dan sehat baik untuk operator maupun untuk instalasi yang ada.

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® 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 cartridge filter

After the CLEANMIST® filter according to standard EN1822-201 in filtration classes
The final cartridge filter can have an efficiency between H10 85% and H13 99.96%.
The cartridges are also available in the active carbon version for odour removal.

CLEANMIST® with Final Electrostatic Filter

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 PC® CYCLONE is a pre-separator which, through centrifugal force, considerably reduces the presence of coarse dust particles.

PC® CYCLONE is used as preliminary treatment of the contaminated stream to partially abate the polluted elements in the air. The standard HFiltration cyclone supply includes the dust collection bin up to Ø1000 mm. To promote the discharge of the abated dust, in addition to the Ø1000 mm, a motorized rotary valve is installed by default below the cyclonic cone.

We suggest using the PC® CYCLONE dust separator as a pre-dust suppressor, paired with our Cart, HJL Bag or Pulsatron Compact® filters. Recommended for a wide range of industrial processes where dry dust and coarse dust or sparks must be treated. The head loss in these cyclones varies between 95 and 130mm H2O.

For heavy duty applications, the pre-separator can be made of wear-resistant steel (HARDOX®).

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

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

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.
