Double Scrubber can now eliminate 1.5 micron or coarser dust from your exhaust
WET SCRUBBER - Principle
WET SCRUBBER
Efficiently collects dust, odor/bad smells, gas/vapor by mixing liquid
with gas containing dusts.
Gas containing dusts is introduced to the narrow pass #2 between the guide plate #1 and liquid surface.
And it is passing through very fast with much liquid, which makes it dispersed
and creates vortex at the scrubbing part #3.
Gas/liquid mixing is done here.

Double Scrubber
Double Scrubber dust removing efficiency (I - 1.5 microns top), compared with single scrubber (I - 8 microns top) for fly ash

◎Typical Problems of Packed
Bed Scrubber◎
1) Easy to clog
2) Often declined gas flow rate
3) Takes time to wash filler
4) Necessity of regular maintenance
of pump and mist eliminator
>>> Solutions
◎ACO Wet Scrubber - holds water inside◎ 1) Requires no pump because gas itself draws water
2) Simple structure makes it possible "No Clogging"
3) No gas flow rate declined because of no clogging.
4) No clogging makes it possible "No Maintenance"
WET SCRUBBER - Features, Applications
ACO wet scrubber is used for various purpose, such as eliminating fine powder, bad smells, water soluble solvent, sticky/greasy
powder, etc. These are all not collected by bag filters. Sometimes they are scattered
in air, which used to be no other choice. Now, there is a solution - use
wet scrubber.

Wet Scrubber Case Study 1
Client:
Glass Manufacturer
Use:
Exhaust gas collection from Borosilicate Glass melting furnace
Situation before installation:
1) In the bag filter, heated and vaporizing Borosilicate passed through
the filter, crystallizing and depositing inside the duct.
2) Filter clogging occurred due to Borosilicate crystallizing in the filter.
3) The factory was covered in dust due to loss of air volume and suction
in the bag filter because of clogging.
Solution:
Collect the crystallized dust while cooling the gas in the scrubber.
Apparatus:
Model Name: Double Wet Scrubber
Model Type: DWS-120-H
Air Volume: 120 m³/min @ 70℃ (4,236 cfm, 158 degree F)
Pressure loss: 2.5kPa (10" water)
Result:
1) After installing a double wet scrubber, bag filter exhaust has been stabilized and suction has been restored, the factory environment has been also improved.
2) Filter maintenance disappeared.
Inside has become very clean in two weeks later.
Wet Scrubber Case Study 2
Client:
Metal Processing Manufacturer
Use:
Metal dust collection
Situation before installation:
Metal dust originating from a belt sander containing sparks
frequently caused fires in the bag filter.
Solution:
Remove the bag filter and replace with a wet scrubber.
Apparatus:
Model Name: Wet Scrubber
Model Type: WS-150-SC
Sludge Conveyor Type
Air Volume: 150 m³/min (5,295 cfm)
Pressure loss: 1.3kPa (5.1" water)
Result:
After installing a single wet scrubber, fires never occurred again.
Al;so, filter maintenance was no longer needed resulting in lower costs.
Wet Scrubber Case Study 3
Successive fire accidents at automobile parts factories. Wet Scrubber
eliminates potential hazards from the workplace and workers are saved from
risky situation.
Client:
Automobile parts manufacturer
Use:
Metal dust collection
Situation before installation:
Repeated fire accidents of dust collector in the process of manufacturing automobile parts were their major problems.
In the first stage of manufacturing, metal powder dust produced in the polishing process of large metallic plate is collected by bag filters. In this process, sparks come off when the metal is curved. The dust collector sucks the spark as well and then burns filters installed inside the unit frequently.
Filter change is fairly costly, and the workers always remain fraught with extreme risk because they need to respond to these frequent fires.
Solution:
They are in search for the dust collector which can prevent itself from
fire accidents. ACO proposed “Wet Scrubber”. The automobile parts company
ordered ACO to design fully tailored dust collector - wet scrubber to replace
the existing filter type dust collectors.
Result:
Wet Scrubber contains water inside and never result in a fire during its operation process, even though it continues to suck sparks together with metal dust.
It is not necessary to change the burnt filter and the workers do not have to cope with danger anymore.
First and foremost, it reduces cost because the filters are not necessary anymore.

Wet Scrubber Case Study 4 [Confectionery Factory]
Troubles when collecting dust including Sticky ingredients
Client:
Potato chips manufacturer
Use:
Collecting dust from potato chips machine
Situation before installation: In the factory, they use dust collecting machine with filter……. but
①Inevitable decline in dust collecting efficiency
②High maintenance frequency
Result:
- No decline of dust collecting efficiency
- No clogging because it uses water
- No maintenance because equipped with Automatic Cleaning Devices
Wet Scrubber Case Study 5
[Oily Smoke Polyethylene & Paper powder]
Dust collection・Deodorization・Fire prevention- by Installation of Wet Scrubber
Case study of oily smoke of Polyethylene and dust collection of paper powder
Before installation - Troubles before installation
• Not wanted to discharge outside the factory, such as oily smoke, paper
powder and odor that occur during production.
• Not wanted to make sticky dust buildup inside exhaust ducts.
• Wanted to prevent fires inside exhaust ducts.
Installation conditions
• Collection of oily smoke, sticky dust and odor.
• Prevention of piling up of dust inside the ducts.
Proposal and Result - Proposal by ACO CO., LTD.
Installation of「Wet Scrubber」which uses water. Wet Scrubber is clog free with sticky oily smoke orand dust with high enough flowing speedthe speed setting of flow rates which prevents from making dust build up inside ducts. As a result, no fire case occurred because fire can be extinguished and odor is rreduced.
Results
• Oily smoke and paper dust discharged outside the factory are drastically
reduced.
• Sticky dust which piles up inside the exhausted duct is drastically reduced.
• Successfully reduced the bad & uniquecharacteristic odor of exhaust.
• Zero duct fire.
• Maintenance is conducted only once in four months, just exchange water.
• It has been working without any problem since the purchase installation
of 2017.
