Stiavelli Irio srl industrial fans and blowers for environmental solutions applied at filtering devices plants have an historical application. Processes and equipments for this sector are several and often very specific. Recycling technologies may be innovative and advanced in concept and design, requiring proper solutions to meet specific requirements.
Environmental Applications. Industrial fans and blowers are used for the treatment of exhaust fumes and emissions processing in dust fan configuration, with pollutant abatement through industrial filtration, separation devices as bag filters, electrostatic precipitators, scrubbers, carbon or cartridge filters. Exhalations, pollutants, gases, fluids containing powders, suspended substances (often abrasive or corrosive) require specific abatement and treatment procedures: our Fans and Blowers has to excell in treatment, in processing emissions from waste incineration, by guaranteeing the maximum efficiency for the highest environmental standards and enhanced solutions and reliability for wastewater treatment plants.
Industrial Induced Draft Fans. They find wide application with pollutants from treatment plants. After the fumes has been draught out, a proper abatement plant is necessary to clean combusted fumes before the emission in the atmosphere. Separation devices work with industrial fans before a chimney provides a proper smoke outlet. The kind of fumes and gas may vary according to the process, because different plants for various purposes work at different atmospheres too. The method exhaust air purification depends on the exhaust air volume and temperature, the type and the concentration of the emitted pollutants, the economic value of the recovered materials. During the treatment of some fumes blowers can ignite sodium carbonate and soda in neutralizer devices for the pH regulation.
Thermal Treatment and Incinerators. Municipal and industrial organic and non-organic waste are a valuable energy source. After a process of shredding, sorting and drying to obtain combustible material, they are burned in incineration plants at high temperatures (depending on the process and the type of waste). They produce energy that may be applied in many useful ways (electric power, heating). Incinerators work not only with municipal or industrial waste but with medical or hazardous waste, wastewaters and sludges, petroleum derivatives. A wide range of Forced Draft Fans supply combustion air for thermal treatments in burner systems.
Biogas Production Plants and Gas Treatment. Fermentation of biological waste is a widespread process for natural gas production. Bacteria enable the gas production during the digestion processes of organic waste, sements, animal manure and biological waste. This gas may be used for electric power production. Gas cleaning systems are necessary to deprive the gas of elements that may degrade the end product quality which is used to fuel and power gas engine or burners. Therefore, biogas may be upgraded to biomethane for the combustion. Flue gas treatment systems are useful to remove hazardous substances generated in combustion process of the gas. Filters and/or wet scrubber are employed for this application.
Operative areas may be classified and require explosion-proof fans and blowers (in compliance with Atex Directive). In the garbage dump, flammable gas and fluids may generate due to various chemical treatments.
