Whether removing dust or recovering product, whether in production or in the surrounding safety system: wherever there is a need to retain solids from liquids or gases, filters play a crucial role.Different manufacturers offer different solutions for the numerous challenges and demands on modern filter systems - we have filtered out a selection for you at Powtech.3: GEA's Biscat filter system features an integrated catalyst matrix and combines three process stages in one system.(Image: GEA)1: The nanofiber material for WAM's Zero series filter elements is now also available in an antistatic version.(Image: WAM)2: The 85870 series of the Flex-on filter cleaning system from IMI Buschjost is designed as an all-in-one solution.(Image: IMI Buschjost)3: GEA's Biscat filter system features an integrated catalyst matrix and combines three process stages in one system.(Image: GEA)4: The Hecht Proclean Conveyor has a filter head with a powerful ring filter system.(Picture: Pike)5: The compact filter system Quad Pulse Package QPP2 PX from Camfil APC combines energy efficiency and dedusting performance.(Image: Camfil )6: For its Pressofiltro filter driers, Comber offers an effective heel break system to break up the residual layer that remains after product discharge.(Image: Comber/Heinkel)7: The mobile small dedusting solution HET compact offers three Hepa filter levels for safe recirculation operation.(Image: HET Filters)8: Herding Flameless sintered plate filters enable flameless and smokeless pressure relief.(Image: Herding)The nanofiber material developed by WAM, with which the own filter elements of the Zero series are equipped, is now also available in an antistatic version.This gives the filter systems the Atex certification for zone 21. The systems are therefore also suitable for systems at risk of explosion, such as in plastics processing plants, mills or sugar factories.The filter systems are characterized by reduced dust emissions and a 30% increase in air volume compared to the previous system.With the nano-coated filter media, it is possible to choose smaller versions of the respective filter series.This is usually also associated with lower costs.The 85870 series of the Flex-on filter cleaning system from IMI Buschjost is designed as an all-in-one solution.Thanks to its modular structure, the system can be tailored to individual requirements.It is easy to integrate into existing systems via plug-and-play.The design and manufacture of the system are based on the requirements of the EN 13445 standard, which is harmonized with the Pressure Equipment Directive 2014/68/EU. A tank up to 3 m long with an internal diameter of 220 mm forms the basis of the system.It consists of a corrosion-resistant aluminum profile and can be fitted with filter valves with a nominal width of DN 40 to DN 65. With a maximum length, it offers space for up to 20 valves.These achieve very fast opening and closing times thanks to high-quality TPE membranes.The series is designed for a maximum pressure drop of 0 bar.The system works without pressure loss and leaks at a medium temperature between -20 and 85 °C, the maximum operating pressure is 8 bar.Depending on the area of ​​application, the system can be supplemented with additional components such as maintenance units and filter controls.The latter indicate the degree of contamination of individual filter elements and give the signal for cleaning as soon as the upper threshold value is exceeded.GEA's Biscat filter system features an integrated catalyst matrix.It thus combines the process stages of dedusting, separation of acidic components and reduction of total hydrocarbons and nitrogen oxides.Inorganic pollutants such as HF, HCl, SOx can be bound by injecting lime-based reagents, and nitrogen oxides can be separated after injecting ammonia.This replaces the traditional Selective Catalyst Reactor (SCR).The high-temperature particle filter is chemically inert and corrosion-resistant.The particle separation takes place with filter elements made of mineral fibers, the so-called ceramic candle.These candles can also be used flexibly when the operating parameters change, especially with high gas temperatures.Flue gases do not have to be cooled, so no thermal energy is lost.The filter elements are cleaned of the separated dust during operation by compressed air blasts.The one-piece or multi-piece housing allows for a filter length of up to 6 m. This means that large gas volume flows can also be cleaned.The structure of the system enables the maintenance of individual elements during ongoing operation.Areas of application are, for example, in the cement and glass industry, in incineration plants, in refineries and roasting plants.The Hecht Proclean Conveyor has a filter head with a powerful ring filter system.The body of the filter represents an extension of the separator tank due to the ring filter technology used. During the conveying process, the product-gas mixture is sucked in from the feed point through a hose or pipe system and passes through the product inlet flap into the separator tank of the conveyor.The vacuum and compressed air unit are attached to the side of the body and therefore do not have to be dismantled when changing the filter, cleaning or maintenance.The filter head makes it possible to use the complete diameter of the separating container as the diameter for the filter.The filter surface is therefore larger than in the previous model, which extends the filter service life and thus the delivery time when sucking in products.Even difficult to convey and very fine products can be conveyed efficiently.The compact filter system Quad Pulse Package QPP2 PX from Camfil APC combines energy efficiency and dedusting performance.It is specially designed for the often limited space in the pharmaceutical and chemical industry.The space-saving and quiet system uses two primary filter cartridges with segmented dedusting.The "Bag-In/Bag-Out" system keeps hazardous dust under containment in a closed filter bag.Filter changes are quick and easy without opening the containment.The built-in Hepa filter achieves a performance of 99.995% in the range of 0.3 μm.The system withstands explosive pressure from dusts up to ST2, which saves additional safety systems such as long shafts for external pressure relief.For its Pressofiltro filter driers, Comber / Heinkel offers an effective heel-break system to break up the residual layer that remains after the product has been discharged.It ensures that the discharge is free of residual layers and ensures the greatest possible product yield.For this purpose, the multi-layer filter plate is pressurized in pulses with nitrogen from below, the remaining layer breaks up and can be discharged by the agitator.The system enables a closed and automated process flow and represents an alternative to manual emptying via glove box. This increases both the efficiency of the process and the safety for the product and operator.The focus of the filter solutions from HET Filter is on modern filtration processes, safe containment up to level OEB 5 and constructive explosion protection.The filter manufacturer also implements the high requirements of the chemical and pharmaceutical industry in suitable systems through close exchange with users.The mobile small dedusting solution HET compact offers three Hepa filter stages as standard for safe recirculation operation.The use of the filter system is also suitable for toxic and respirable dust.The filter change takes place without contact with dust thanks to the proprietary Safe-Change-System.In the event of an explosion, the Herding Flameless sintered lamella filters enable not only flameless but also smoke-free pressure relief.While conventional solutions for flameless pressure relief cannot hold back smoke or burned and unburned dust, the rigid sintered plate filters are sufficiently stable to counteract this: the explosion in the raw gas space can be guided through the filter elements.As with filtration, the dust can be held back.The flame is smothered in the dimensionally stable sintered plate filter and the pressure is dissipated via a bursting disc on the clean gas side.The effect as a flame barrier has been proven based on ISO 16852.Sintered lamella filters are also insensitive to alternating loads from filtration and cleaning, which extends their service life.The lamella shape also increases the filter surface by up to three times compared to the envelope surface.Do you already know our practice conference Containment?There you will learn how containment solutions can be easily implemented in practice, where interfaces in containment can be avoided and how they can be implemented safely and much moreI agree to being informed by chemietechnik.de via email about magazines, online offers, products, events and downloads from the industry media network.I also agree to the evaluation of my use of the newsletter to optimize the product range.I can revoke this consent at any time with effect for the future by unsubscribing from the newsletter.I have read and acknowledged the data protection information.By registering, I accept the terms of use of the portals in the industry media network.I have taken note of the data protection declaration.Detmolder Strasse 256 32545 Bad Oeynhausen GermanyLudwigstaler Strasse 149 78532 Tuttlingen GermanyCOMBER Process Technology SrlPalazzo Cassiopea 1 Via Paracelso, 22 20864 Agrate (MB) ItalyPeter-Müller-Strasse 12 40468 Düsseldorf GermanyHEINKEL Drying and Separation GroupProleit's Plant iT Batch Orchestration System (BOS) is equipped for all batch management requirements.Read more...Due to the current energy crisis, diesel fuel will be used primarily for production and cleaning services for maintenance will be postponed.However, regular maintenance is the be-all and end-all for proper system operation.But it is also possible without diesel fuel and drinking water consumption.Read more...Afriso-Euro-Index presents the revised pressure transmitter DMU 13 Vario, a further development of its predecessor DMU 13, with, among other things, a significantly larger measuring range.Read more...Henkel's venture capital arm invests in Direct-C to expand its maintenance, repair and overhaul (MRO) business.The start-up has developed sensor technology for the early detection of leaks in liquid hydrocarbons.Read more...Various Hessian companies have called for an accelerated ramp-up of the hydrogen economy in the federal state.In view of the geopolitical situation, "quick action is now required".Read more...
