ppt on venturi scrubber

Named after an Italian physicist, the Venturi effect occurs when gas or fluid is pushed through a throat, or choke, to increase the velocity of the fluid or gas stream passing through. The wet scrubbers discussed in this chapter use water to remove particulates, gases, or both from industrial gas streams or stacks. Venturi scrubbers - air or gas velocity is increased through a venturi shape - increased turbulence atomize the water droplets; Fiber-bed scrubbers - air passes through wet-laden fiber mats where mists are collected. Additionally, the system is an excellent choice for explosive dust applications. The energy from the gas atomizes the liquid, allowing particles and pollutants to be entrained in droplets. Type of Technology: Removal of air pollutants by inertial and diffusional interception. Water is injected at low pressure into the throat of the venturi through which the gas stream passes at high velocities. The dust/gas mix flows through the venturi tube and reaches top speed in the throat section. Venturi scrubbers are also known as venturi jet scr ubbers, gas-atomizing spray scrubbers, and ejector-venturi scrubbers. MONTHLY SCRUBBER INSPECTION FORM Facility Name: Facility Location: Process: Scrubber ID: Date of Inspection: Time of Inspection: Name of Inspector (Print): Signature of Inspector: INSPECTION ITEM COMMENTS/CORRECTIVE ACTIONS 1) Gas pretreatment equipment Piping Leakage Valve Operation Pump/Lub. 1. Applicable Pollutants: Venturi scrubbers are primarily used to control particulate matter (PM), including PM less than or equal to 10 Enviropol is the best-wet scrubber manufacturers in India. Recirculate Clean Air to Reduce Climate Control Costs The Sly Venturi Scrubber offers more advantages in separating and recovering liquid mists and ultra-fine particulate than other gas cleaning methods. A venturi scrubber consists of a converging section, a throat (the narrowest part of the venture tube) and a diffuser. Venturi Scrubbers. Water chemistry is often extremely complicated in these scrubber systems because of the variety of oper-ations occurring simultaneously in the scrubber environment. The Sly Venturi Scrubber serves industry in several ways. CONFIGURATION CONCEPTS (BASED ON THE CONNECTED E/G STREAMS) Determined by the type/number equipment connected on the Scrubber’s Unit Stream The size of the Scrubber determines the amount The numerous advantages are wet scrubber like separation of two-tower, higher scrubbing efficiency, an operation is trouble-free, a requirement the low-water, a wide range of applications. Venturi scrubbers are scrubbers with a venturi shaped chamber with converging and diverging sections. Venturi Scrubbers Similar to the IGS scrubber Easier Drain of the Process Water . Not suited if solid particles are present in the air since the fiber mats may plug; It supplies high-quality wet scrubber and venturi scrubber globally at the most competitive prices. A type of Wet Scrubber, the Venturi Scrubber uses Venturi technology, which has been used for over 100 years. bed scrubber for upgradation of biogas using a closed-loop process: An economical and environmental approach” submitted by Mr. Sudhir Sah (110ME0528) in partial fulfillment of the requirements for the degree of Bachelor of Technology in Mechanical Engineering at National Institute of Technology, It removes pollutants present in process gas streams. This includes removing hazardous and nuisance dusts, fumes and mists from stack gases. 8.
