Filter Technology & Gas Cleaning

Outstanding cleaning performance combined with an excellent degree of separation

The Scheuch IMPULS filter is a high-capacity filtering separator that delivers outstanding cleaning performance combined with an excellent degree of separation. It is used for the dry separation of solid matter, primarily in the extraction of contaminants from machinery and the workplace, as a process filter in material recycling or for conveyed material separation purposes.

The patented IMPULS cleaning system

Thanks to the specially shaped twin nozzles on the jet pipe, the pulsed free jet pulls along an envelope of clean gas from the primary compressed air as it makes its way to the injector. The two gas flows are mixed in the injector by means of pulse exchange and, at the same time, experience a significant increase in pressure. This ensures highly efficient cleaning throughout the bag length and filter bags that require cleaning less frequently.

Proven practice for decades, the IMPULS cleaning system has become a byword for low operating costs:

• Low compressed air consumption
• Long service life demonstrated by filter media
• Very little maintenance or servicing required

Fuel Processing – Cement Industry

Processing fuel – of both the primary and secondary varieties – requires dedusting plants to have specific designs to accommodate explosion protection measures and monitoring equipment.

Generally, filter plants are designed to be pressure shock-proof in accordance with VDI 3673 and have extensive safety equipment such as pressure relief stacks, explosion flaps and function monitoring for cleaning facilities.

Dedusting plant components must meet a range of safety requirements according to the ATEX directive and their defined zone. In this respect, you will benefit from the in-depth, cross-industry expertise that Scheuch GmbH possesses in the area of explosion protection, as well as from tested components and autonomous protective systems.

Material Processing & Handling – Cement Industry

When it comes to auxiliary dedusting facilities used in tasks such as crushing, grinding, transportation, storage and packaging, compact filter plants installed directly at the source of emissions are becoming an increasingly popular choice.

For these applications, Scheuch offers a complete, finely graded range of filters that are proven in practice, accommodating volume flow rates of 200 to 20,000 Bm³/h. Depending on the space available and the volume flow rate, there is the option of installing filter bags either vertically or horizontally and using filter cartridges. These filter plants are supplied pre-assembled, equipped with bags, and ready to connect – and can come with the option of installed fans and silencers.

Packaging Area Dedusting – Cement, Lime & Plaster Industries

The packaging area is where materials are packed or placed into containers for transportation. Therefore, this is another area that is subject to dust accumulating and, as a result, requires an extraction solution. Packaging area dedusting forms part of a plant’s auxiliary dedusting measures.

Hydrator Dedusting – Lime Industry

The process is referred to as dry slaking or wet slaking according to whether hydration leads to a dry or wet hydrate, which itself depends on the quantity of water that is supplied.

The benefits of dry hydrator dedusting:

• Filter is installed directly on the slaking trough
• Water steam vapour is dedusted
• Solids are fed back into the production process immediately
• No intensive, high-maintenance wet dedusting processes

Crushers, Screens & Sorting – Lime & Plaster Industries

Auxiliary units used in applications such as crushing and screening raw materials or sorting are subject to significant accumulations of dust, and dedusting plants for processing this need to be selected and coordinated with the same level of care as would be taken in any other application. Decentralised, compact dedusting solutions installed directly at the source of emissions are becoming today’s systems of choice.

Mills – Lime Industry

The lumpy material is transported to the silo plant on a conveyor belt and is either sold in its lumpy format or ground into fine material. The grinding process produces extremely fine dust in significant quantities: it is not unusual to see as much as 1,000 g/Bm³. A key requirement in these applications is a uniform filter inflow in order to ensure efficient material recycling.

Conveying Path Dedusting – Lime Industry

Auxiliary units used in applications such as transport and storage are subject to significant accumulations of dust, and dedusting plants for processing this need to be selected and coordinated with the same level of care as would be taken in any other application. Decentralised, compact dedusting solutions installed directly at the source of emissions are becoming today’s systems of choice.

Mixers, Weighing Devices, Silos – Lime & Plaster Industries

Auxiliary units used in applications such as mixing raw materials or storage are subject to significant accumulations of dust, and dedusting plants for processing this need to be selected and coordinated with the same level of care as would be taken in any other application. Decentralised, compact dedusting solutions installed directly at the source of emissions are becoming today’s systems of choice.

Coolers and Conveying Paths – Plaster Industry

Auxiliary units used in applications such as cooling or transport are subject to significant accumulations of dust, and dedusting plants for processing this need to be selected and coordinated with the same level of care as would be taken in any other application. Decentralised, compact dedusting solutions installed directly at the source of emissions are becoming today’s systems of choice.

Saws and Bundlers – Plaster Industry

The continuous boards that are created during plasterboard production are sawn, cut into various shapes and bundled. Scheuch provides the ideal extraction solutions for saws and bundlers.
