Reliable dust removal was a task for specialists even at the beginning of the last century. Bag filters of Intensiv-Filter contribute to an improved environment for almost 94 years now. Also today the industrial dust removal has a mean significance. Modern technologies for efficient dust removal are a trend subject due to environmental impacts, climate change, rising energy consumption and conservation of natural ressources of renewable raw materials. As technology leader in industrial de-dusting we offer complete and tailor-made solutions in the area of dust removal technology and product recovery.

2. Customized solutions for industrial dedusting systems f
As a specialist for dedusting processes, we
manufac-ture and install dedusting systems for
exhaust volu-me flows from 2,000 m³/h to over
2,000,000 m³/h. Filter bags up to 10 m lengths
are used for higher flow rates.
Depending on the industry many different dedust-
ing problems have to be solved. This applies to
very complex processes flue gas cleaning. Beside
the dedusting process, toxic gas components as
well as heavy metals and polychlorinated
hydrocarbon compounds have to be separated.
Most severe hygienic and safety regulations must
be met in the food processing industry. In other
industries, e. g. cement production or power plant
technology, the emission sources are very nu-
merous so that high exhaust volume flows have to
be dedusted.
The variety of processes generates most different
types of dusts. They differ amongst others in
partic-le size, chemical properties, moisture
content and mechanical properties.
In addition to dust properties, the gas compositi-
on is of major importance. Furthermore, explosion
protection must be taken into account in many
pro-cesses due to combustible dusts and gas
composi-tions.

8. Competence partner for your application
Dairy and Food industry
When processing milk and other fluid foods to pow-
der products by spray drying plants, our filtration
plants are often part of the production process.
Here, we ensure the highest hygienic and statu-
tory requirements. Highly efficient product reco-
very and out-signed security concepts are further
strengths which distinguish us.
By using the gained products and the possibility of
recirculation into the production process, short
payback periods are achieved for the filter system.
As a result, it provides fast additional income for
the operators.
Worldwide, a multitude of filter systems are suc-
cessfully in operation. Of course, we also offer de-
dusting solutions for all other processes in the
food industry.
We assist you from production to conveying and
packaging of disperse substances such as sugar,
grain and other powdery food.
We provide safe equipment for your demanding
tasks due to explosion-proof filter systems.

9. The CIP process
In order to avoid product loss, the processing air is
passed through dust collectors. This can be cyclo-
nes but also filtering separators.
In both cases, the system components are washa-
ble, this means they are “cleaned in place” (CIP).
Filter with CIP technology are hygienically cleaned
from product residues by special patented washing
facilities without removing the filter media.
The „CIP filters“ are used for applications where
frequent product changes, product aging or pro-
duct contamination by germs and bacteria forma-
tion make a cleaning of the filter necessary.
The process is characterized in particular by dry
filtration with jet pulse cleaning and subsequent
washing cycles. The dry filtration process is restar-
ted after dehumidifying of the filter plant.
The product-laden volume flows, which are direc-
ted to the filter plants, amount up to 300.000
m³/h in operating condition. Filter bags with a
lengths up to 7 m can be provided.

10. ProSorp: Dry Scrubbing for simultaneous dust and corrosive gas se-
paration in power plants and thermal waste recycling facilities
The power generation from fossil and other solid
fuels will continue to play a major role. However
thermal reaction of fossil fuels such as coal and
lignite in power plants generate solid and gaseous
harmful substances.
The use of alternative fuels such as municipal was-
te and sewage sludge involve these problems as
well. Accordingly, flue gas cleaning plants are ne-
cessary to meet federal emission requirements.
These systems consist of separating units for de-
dusting of fly ash and acid gases in form of sulfur
dioxide, hydrogen chloride and hydrogen fluoride.
Further harmful substances to be separated are
heavy metal types as well as dioxins and furans.
Besides, wet flue gas cleaning processes, well ad-
vanced filters, the so-called dry scrubbing plants
are used. In addition to dedusting, the reduction
of gaseous pollutant emissions is ensured. For
this purpose, alkaline working additives are
dispersed into the raw gas in combination with
sorbents with high internal surfaces.
Partly reacted additives are recirculated with high
recirculation rates after a so-called conditioning
phase, in order to achieve a better additive utili-
zation.
Semi-dry processes are used besides dry flue gas
cleaning. Here, the additives are added as fluids
through spray drying into the process.
All legal requirements, such as the 17th BlmSchV,
are reliably observed, when operating our facilities
in accordance to our operating guidelines.

11. Pit and quarry industry
Until the use of efficient bag filter plants, the dust
emissions of e. g. rotary kilns amounted to about 3 -
5 percent of the production volume. Nowadays, the
dust emission level in the exhaust gas of rotary
kilns is approx. 20 mg/m³ in daily average due to
installa-tion of bag filters. Also the input of
alternative fuels is restricted by strict statuary dust
emission limits. The operation of process filters and
flue gas cleaning systems enables this input.
From raw material conditioning to packaging, every
dust source in cement and limestone production
can be handled by process filters.
Clean gas dust contents of < 10 mg/m³ can be
achie-ved with filter systems of Intensiv-Filter
Himenviro; both when operating with high raw gas
dust loads during mill operation and in the field of
clinker cooler dedusting. We offer compact filter
units for relatively low flow rates, too.
Steel, iron, non-ferrous metals
In almost every process in steel/metal industry
process filters are required. Wherever metals are
melted, moulded and refined, polished or milled,
emissions are produced in terms of dust, smoke,
soot or fumes. Depending on the end product, the
deposition of dioxins and furans, heavy metals or
corrosive gases, as sulfur dioxide, hydrogen chlo-
ride and hydrogen fluoride, is necessary. High
operating temperatures and critical gas compo-
nents put high requirements on the filter system.
Intensiv-Filter Himenviro systems are prece-dent-
setting for these applications. These inclu-de
dedusting applications in sinter plants, steel
production, aluminium factories, production and
processing of raw material, but also in the recyc-
ling of metallurgical materials.
