Not using the "trade" of test
planning, production after the
principle „trial and error“ is still
valid for some extend. However, the effective conversion
of known and proven technologies help to improve the
problem understanding substantially and besides to minimise costs for the product
development and also design
of the plant. And what deals
CFD (Computational Fluid
Dynamics) with it? CFD awakens ideas, CFD reveals,
CFD prevents mistakes. Modern CFD programmes permit
the simulation and analysis of
flows on the computer. The
computer-supported analysis
technology enables to examine the dynamic of flowing
media and provides a computer model which represents
the examined conditions of an
installation.
The
special
strength of CFD simulations
lies in the fact that experiments, which are practicable
in reality only with high effort,
can be limited to the most necessary and optimum solutions of the problem statement
are possible with a minimum
of effort.
Also Intensiv-Filter, a leading
manufacturer of filter plants
for the cement industry, avails
itself of CFD-simulations.
Because of the way the system operates, high exhaust
gas amounts to be cleaned
are typical for the cement
production. Therefore bag filters are basically installed for
the dust removal. Only they
are able to keep with the increased legal emission limit
values under all conditions.
Beside low investment costs
and maintenance costs the filter plants must also contribute
to the increase of energy efficiency. Exhaust gas amounts
from 1 or 0.5 million m3/h n.c
are cleaned at cement mills
as well as cooler and bypass;
even to 2 million m3/h n.c for
the kiln / raw mill dust removal. Improvements which
lead to a reduction of the
pressure loss play an important role in this regard.

Successful start for the
ProJet smart® on the POWTECH
The course of the trade fair
POWTECH 2010 has underlined the upward trend in the
German machine and plant
manufacturing. Also IntensivFilter presented itself successfully for the POWTECH
2010. The raised investment
readiness was considerably
perceptible on the exhibition
stand and in the conversations.
As a new innovation the ProJet smart® was issued, the
new with ProTex energy savings filter media equipped
compact filters. With the objective of process optimisation, reduction in costs and
economic efficiency the dust
removal specialist has developed an optimised compact
filter which is tailored to respective
applications.
Equipped with fitted fan and
silencer as well as accompanying cleaning control system,
these new compact filters are
the quickly available and inexpensive dust removal solution. The ProJet smart® is
conceived as a compact filter
with dust collection hopper or
bunker filter with optional bypass flap modular design. It is
based on four filter heads
which are combined with four
lengths of filter bags. Filter
surfaces between 20 and 140
m² can be realised with this
system. This corresponds to
an air flow range of 1,000 to
17,000 m³/h.
Due to the reduction of the
pressure losses by the used
ProTex filter medium, the operating expenses of filter
plants of Intensiv-Filter can be
lowered up to 40% compared
to conventional bag filters.
With the very keen interest of
the visitors, Intensiv-Filter
sees the confirmation for their
product politics oriented in the
market. Many conversations
led in concrete proposals
whose conversion was also
timed on the fair. After this resonance Intensiv-Filter will be
represented again on the next
POWTECH: From October 11
to 13, 2011 in Nuremberg.
New CIP filter for the
spray-drying plant Sloten
Since 1958 the Dutch company SLOTEN B.V. produces and sells breeding products
for
land-economic
young animals. The spraydrying plant to which all raw
materials are delivered liquidly and after pasteurisation, homogenisation and
spray-drying are processed
to protein-fat concentrates is
located in the city of the
same name. Sloten is one of
the few companies in the
world that uses spray-drying
technology for the exclusive
production of animal feed
ingredients..
Intensiv-Filter received the
order for the delivery of new
CIP filters (Cleaning-InPlace) for three spray dryers
The CIP filters are laid out
3
for 67,000 m /h respectively
3
twice for 120,000 m /h each.
The commissioning of the
product filters will be carried
out at the beginning of November, 2010
Internship in the „Technikum“
The new project of the federal ministry of education
and research has the aim to
inspire young people for a
technical physical-scientific
study. The industry in this
country – from the investment construction up to the
solar technology – is depended on graduates of the
fields mathematics, informatics, natural sciences and
engineer's sciences or technology (MINT).
New advertising appearance
There are some extras
going along with the Technikum-internship: Training period companies and universities co-operate for the period of the internship. The
universities can invite the
Technikum-participants for
example to lectures and excursions or support them
during their training period.
In parallel she or he gets to
know courses of MINTstudies in co-operating universities.
The advertising appearance
of
Intensiv-Filter
has
changed. „Less technology
– more emotion“ was the
motto for the design of the
new advertisement of Intensiv-Filter.
Also Intensiv-Filter gives to
young people after their
graduation the opportunity to
collect practical experiences
in a technical company. The
trainees contribute on special projects for five to eight
months at Intensiv-Filte. For
training period of the Technikum-internship we cooperate with the university of
Wuppertal.
With the new
slogan „Cut
operating
costs“
and
the
outstretched
hands,
the
advantages
of the use by
Three E and
ProTex
are
underlined.
The new advertising
campaign
demonstrates that the customer can lower the operating costs of his bag filter
plant alone by the choice of
the right technology and the
right filter media.
Figures, dates, facts
Three high-school graduates
have already begun with
their training period at Intensiv-Filter. „We want to use
the time between school and
study reasonable and collect
practical experiences in a
technical-scientific
field
which we can integrate in
the later choice of the
course of studies. Additionally, we get to know the daily
work routine and can make
a better decision on which
professional sector fits to
our interests and abilities“,
according to the trainees in
unison.
With the production of lead
from ores and scrap metal
above all dust containing of
lead is released.
Depending on aerial relations the dust load amounts
in companies equipped according to the state of the
technology between 340
and 1,160 g of dust of lead/t
of produced lead. The dust
of lead consists of lead from
30 to 55%, the rest are varying shares of zinc, copper
cadmium, antimony and arsenic. According to “TA Luft”
1986 the issue of dust from
lead may amount at most to
10 mg/m3. Thanks to bag filter plants of Intensiv-Filter
the limits are complied.
