Good air quality that meets the standards of DSEAR (COSHH) is a prerequisite for

waste processing plant operators, employees and indeed for their neighbours.

Dantherm Filtration’s wide ranges of dust filtration and material separation

equipment enable their experienced engineers to remove airborne pollutants

whilst also playing a part in sorting waste materials.

Close working with plant designers and operators will ensure that the

extraction equipment becomes integrated effectively with the whole

system. The company naturally offers best available techniques (BAT)

to ensure compliance with all relevant regulations including ATEX

certification requirements as appropriate.

A dust extraction system from

Dantherm Filtration fulfills the ATEX demands:

• Explosion strengths of filters and protective systems independently tested

• EC-Type Examination certificates for all explosion panels, rotary valves and other

protective systems

Waste management and recycling

processes generate dust that must

be minimised, typically requiring

an effective coarse separation system

together with dust extraction for

finer particulate matter.

Dantherm Filtration manufactures all

key items of equipment used in such

installations and thereby offers a high

quality cohesive system with readily

available parts and service to ensure

a long trouble-free life.

Dantherm’s in-house design and manufacture

includes reverse air and reverse jet cleaned

bag and cartridge filters, fans, Nordfab QF

ducting, discharge devices and specialised

comprehensive control systems with easy to

use touch screen funcionality and monitoring

as appropriate. Minimum energy use is assured,

with inverter drives to continuously match the

system requirements.

Total quality control of design,

manufacture, installation and

after sales service will ensure

a long life and hence minimal

depreciation.

As an integral part of materials recovery facilities (MRF),

Dantherm provides highly efficient dust extraction at

conveyor transfer points together with separation of

light material from pre-separated co-mingled material

lines. Strategically placed Dantherm air knives may be

used to clean the resulting material streams by

removing “lights”, which are then separated from the

off-take airstream by means of continuously rated

Dantherm NFV coarse separators. The dusty air from

these processes, together with that from conveyor

transfer points and other hoods may be filtered by a

common high efficiency Cyclopac reverse jet cyclonic

bag filter with patented features to maximise dust

loading with the lowest energy requirement. The

combination of air knives and NFV coarse separators

effectively removes lightweight material, for example

from container or paper lines and the large volume

rotary valve integrated into the NFV separator delivers

this waste at atmospheric pressure for further

processing. Dantherm Cyclopac filters are ideally

suited to this purpose as they occupy minimal floor

space and their fully ATEX certified explosion relief

at high level offers increased versatility when locating

the units in restricted spaces.

FS flat bag filter Features:

• Heavy gauge fully welded steel construction

• Compact modular design minimises space

requirement


• Filter area up to 2500m2 in single housing

• High efficiency off-line cleaning during

continuous operation

• Lower pressure cleaning minimises emissions

• Wide range of filter media for special applications

• Easy access for maintenance from front mounted

clean gas chamber


• No compressed air required

The FS is a range of modular reverse air cleaned

horizontal flat bag (or "cassette") filters designed

for continuous operation in heavy duty

applications. It has a downflow design, dirty gas

entering via an inlet hood at high level, passing

downwards across the horizontal bags where the

dust is separated from the gas. Most of the dust

then drops into the hopper. The cleaned gas

passes through the bags, on the surface of which

a filter cake is deposited, then into the clean gas

chamber from where it is extracted at low level.

Typical Applications:

• Waste incineration

• Aluminium production

• Ferrous and non-ferrous foundries

• Asphalt production

• Quarries, minerals, aggregates

Options for FS and FD filters:

• Discharge options include screw conveyors,

rotary valves, gravity or motorised flap valves

or bin

• Customised dirty gas inlet hoods

• Air blast coolers for higher temperature

applications

• Pre-separators, skimmers and cyclones

• Access platforms

Offline effect advantages:

• Small difference between gross and net surface

• Powerful low energy cleaning

• Low residual dust content

• Very high efficiency in collecting fine dust

(PM10, PM 2,5)

Cleaning is effected by a cleaning air fan whose flexible

outlet duct is connected to a movable cleaning carriage.

A quick acting valve allows a pulse of cleaning air to be

injected into each row of bags in turn, whilst adjacent

rows are shielded to take them off line. This feature greatly

enhances the cleaning efficiency, allowing the filter to

operate normally whilst cleaning progresses.

Operation of the cleaning mechanism is programmable

according to requirements.

FD flat bag filter

Typical applications:

• Incineration and other combustion processes


• Asphalt production


Reverse jet compressed air cleaning system

Reverse jet cleaning is effected by separate diaphragm

valves fixed above each vertical row of filter bags,

supplied by a distribution manifold horizontally

mounted at high level. A pulse of cleaning air is

injected via a vertical jet tube into each row of bags

in turn. Operation of the cleaning mechanism is

programmable according to requirements. The FD is

a reverse jet cleaned alternative to the FS reverse air

filter, particularly useful where the higher quantity of

cleaning air injected by the FS could adversely affect

the process gas conditions.

9 www.danthermfiltration.co.uk Tel. +44 (0)1132 739 400


The FD range is based closely on the efficient FS

reverse air filter, but it is fitted with a compressed

air reverse jet cleaning mechanism. The cleaning

jet tubes are mounted vertically and the top

mounted diaphragm valves are arranged to clean

one column of bags with each pulse. With no

moving parts in the clean air chamber and higher

temperature capability, the FD is particularly

suitable for flue gas cleaning in boiler and

incineration applications.

Arrangement of bags in FS and FD

filters

The flow of hot gases

The hot gases flow into the cooler vertically

downwards along the cooling elements.

The gases are deflected through 180° and

a pre-separation of the coarse dust takes

place. Cold air fans blow ambient air through

the cooling elements. A temperature control

element switches the necessary number of

cold air fans on.

The danger of the dew point

The cooling air has to be pre-warmed if it is

likely that the temperature could fall below

the dew point on the cooling elements

during the cooling of hot process gases.

Unlike KS, preheating of cooling air is

provided with KU. In this case, a partial

flow of heated cooling air and fresh air

are blown in together by the cooling

air fan. A pre-selected mixing temperature

is regulated prior to entry into the cooling

elements by opening or closing the fresh-air

valve.

The recirculation of additives minimises additive

consumption and consequently the occurrence of

residual products. Here too, our engineers have

developed a wide range of processes such as the

Rotosorp process with or without moisturised

recirculation.

Optimum fine dust collection through the synergy of cleaning processes and special filter media.

With the filter media tailored to the respective cleaning systems, we are already able today

to meet the stringent EU regulations for fine dust (PM10). This has been confirmed by latest

research by the University of Karlsruhe. As a customer, you too can benefit from this

enormous lead in know how.

Adsorption and absorption can be combined

by mixing different sorbents to influence the

separation of pollutants.

We are able to provide a vast range of versions to

comply with customer-related demands. In do-

ing so, we use system components such as mixer

reactors that achieve an optimum separation of

pollutants such as HF, HCL and SO2 through an

homogenous mixture of additive and crude gas

flow.

Dangerous Substances and Explosive Atmospheres

Regulations (DSEAR) Rigorous Enforcement

Airborne dust and fume in the workplace must be controlled to protect the health of

personnel. In May 2008 the Health & Safety Executive (HSE) introduced new guidance

relating to COSHH regulations and the mandatory regular thorough examination and

testing of “local exhaust ventilation” (LEV) equipment. This follows a mandate by the

Government to HSE to reduce the incidence of work related respiratory disease. All

such installations must by law be tested and inspected at 14 month maximum

intervals. A detailed report, which compares with original commissioning data is a

legal requirement. HSE have now trained their inspectors to fully understand these

tests and they are equipped to take their own measurements if required to verify data.

Maintenance for long life and economy

It goes without saying that a neglected machine will finally bite back with costly inconvenient

breakdowns. However, day to day energy costs may also become much higher, replacement

parts will be required more frequently and its shorter lifespan will increase the rate of

depreciation. The use of non-standard “pattern” replacement parts, in particular inferior filter

bags or cartridges can prejudice performance and prove to be a false economy.

service in accordance with COSHH. Please ask for details.
