This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers. The results show that the pressure drop depends significantly on the gas flow rate. The scrubber is very simple to operate as it has no moving mechanical parts. Wet scrubbers remove particles from gas streams by capturing the particles in liquid droplets and then separating the droplets from the gas stream. The filtered containment venting system fcvs is a safety relevant system, which consists of venturi scrubber and a mesh filter. The venturi removes the majority of the particulate and the acid gases. Particleladen exhaust gas enters the scrubber where it becomes in contact with a mist of tiny droplets of scrubbing fluid. A venturi scrubber is designed to effectively use the energy from the inlet gas stream to atomize the liquid being used to scrub the gas stream. Fcvs needs to be further assessed to improve the existing.
Particle collection and pressure drop in venturi scrubbers. To correctly size and design these equipments, detailed information on the fluid dynamics is very important. Numerical simulation of flow behavior within a venturi. Equipamentos e maquinas aplicados em diversos setores como. Venturi scrubber case studysummary venturi scrubber case studyfor engineers. Graphical analysis of the performance of venturi scrubbers. Venturi scrubber systems incorporate a scrubbing vessel with a system fan, recycle pump, instrumentation and controls, mist eliminator, and exhaust stack. The dimensions and operating parameters correspond to industrial applications. Exhaust gas scrubber training video convergence training. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers venturi devices have also been used for over 100 years to measure fluid flow venturi tubes derived their name from giovanni. This module will discuss the major components as well as the purpose and operation of an exhaust gas scrubber. These gases are often treated to remove pollutants in order to meet environmental regulations. Login or register free and only takes a few minutes to participate in this question you will also have access to many other tools and opportunities designed for those who have languagerelated jobs or are passionate about them.
Numerical simulation of flow behavior within a venturi scrubber. Pressure drop and liquid distribution in a venturi scrubber. Pressure drop and liquid distribution in a venturi. One of the most efficient wet particle collectors is the venturi scrubber 6. Venturi scrubbers are scrubbers with a venturi shaped chamber with converging and diverging sections. Venturi scrubbers are widely used to control industrial emissions, because of their high efficiency in the removal of particles from gases. The scrubber system receives hot gases, which may be as hot as 1650f, from the furnaces and contacts the gas with atomized scrubbing solution in the venturi. The present work details the threedimensional numerical simulation of singlephase and twophase flow airwater in a venturi scrubber with an inlet and throat diameters of 250 and 122. The objective in this article is to deal with venturi scrub. Numerical simulation of the flow was performed using software fluent 12. Venturi scrubbers are simples, low cost and highly applicable equipments. Development of a computational model of venturi scrubber to simulate its performance for filtered vented containment system. Particulate venturi scrubber systems tailored to achieve your goals.
Venturi scrubber venturi wet scrubbers particulate. Design otimizado, com grande robustez e durabilidade grande resistencia a desgaste e corrosao. The outotec venturi scrubber is a highpressure scrubber that cleans electric furnace offgas and effectively pressurizes the co gas line. The purpose of this article is to study, both experimentally and through cfd simulations, the fluid dynamics of the gas and liquid phases in the. A series of low pressure, large orifice spray nozzles direct the scrubbing solution into the system. The basic principle of a sulfur dioxide scrubber system is the removal of so 2 by using its chemical characteristics to combine with water. A wet scrubber is one method that can be used to clean a gas stream by bringing the gas into contact with a liquid. Our experienced design team is focused on developing a solution which will fit your application and. Industria ceramica, industria coureira, industria quimica, alimenticia, mineracao e fundicao. Pollution systems is a leading manufacturer specializing in particulate venturi scrubbers.
