FLUE GAS FILTRATION AND DEDUSTING. Ventilex and the Environment. Ventilex started building air pollution control systems for industry 50 years ago to cooperate with the fast growing needs of the environmental market and the severe legislation in Holland. Very soon the experience and success of Ventilex in building air pollution control systems expended all over Europe, especially in the field of the industrial process related applications of flue gas filtration and dedusting. The air pollution control systems engineered and supplied by Ventilex are always using in house designed filtration equipment, most of the time constructed in our own workshops in Holland. In this way, Ventilex is controlling the high quality level of the equipment. Although all the Ventilex air pollution control equipment is constructed according to the international standards, most of the systems will be tailor made in order to optimize the performance in function of the application. Summary of Ventilex air pollution control equipment; ▫ ▫ ▫ ▫ ▫ ▫ ▫ ▫ Jetbag fabric filters, with automatic pulse-jet cleaning (on-line and off-line). Gas filtration at high temperature, using stainless steel sintered fibers filter elements. High efficiency cyclones. Venturi scrubbers. Packed bed wet scrubbing towers. Dry gas scrubbing reactors. Dry scrubbing products storage, dosing and injection systems. Gas coolers. JETBAG Filter

Applications air pollution control systems. Most of the air pollution control systems use "dry" gas filtration with a Ventilex Jetbag pulse-jet fabric filter. Using dry filtration gives important advantages compared to other systems, such as wet systems. The advantages of dry filtration systems are: very high filtration efficiency (solids emission levels < 1 mg/Nm³), dry handling and storage of the collected solid dust particles and eventual validating of the collected dust (no waste water), smaller energy consumption, and less maintenance. For these reasons Ventilex shall only use wet...

Abrasive dust filtration: the major operating parameters which will determine the life time of the filter elements and the risk of abrasion on the steel parts of the system are gas velocity and gas distribution in the system (wear by abrasion is related to gas velocity in an exponential way). In addition to the special design for gas velocity and distribution, some parts of the system will have a special design by using wear plates and abrasion resistant steel for construction (baffle plates, dedusting piping bends, etc..) JETBAG - Filter on abrasive dust from sand dryer. Filtration of very...

Dry gas scrubbing and filtration to eliminate gaseous (HCl, HF, SOx, dioxins and furans, etc.) and solid pollutants Certain applications of gas filtration, mostly related to thermal process systems (waste incineration, melting furnaces, etc..) contain also gaseous pollutants such as HCl, HF, SOx, dioxins, furans, etc..) which can be very dangerous for the environment. These hazardous gaseous pollutants have to be eliminated, together with the dust particles. To solve these problems, Ventilex uses a "Dry Gas Scrubbing and Filtration" process, based on the dry absorption of the gaseous...

Hot process gas filtration (up to temperatures of 800°C). For some industrial processes it is necessary to filtrate the hot process gas, without cooling, for example to allow recycling of the gas in the process or energy saving reasons. For these special applications Ventilex uses a special Jet-bag filter design with heat resistant filter elements, made in stainless steel micro fibers (max. design temperature 800°C). JETBAG FILTER with stainless steel fibres filter elements JETBAG FILTER with automatic cleaned gas cooler

Wet scrubbing. Although in most of gas filtration applications, dry filtration by mean of a fabric filter is the best technology, in some cases gas filtration by wet scrubbing can be advisable for different reasons such as: hot gas which is difficult to cool before filtration, or, the possibility of waste water recycling into the process. In the Ventilex program we use three types of wet scrubbers: - Dynamic scrubbers, composed of a centrifugal turbine (fan) with water injection at the turbine inlet, followed by a wet cyclonic separator or demister. - Venturi scrubbers, where the solid dust...
