A venturi scrubber consists of a converging section, a throat (the narrowest part of the venture tube) and a diffuser. The dust/gas mix flows through the venturi tube and reaches top speed in the throat section. Thereafter, the mixture passes into the diffuser where the speed drops again. Liquid is added to the gas flow either in the throat section or prior to it. Intensive mixing takes place between the gas and the liquid in the throat section of the venture tube. Due to the high speed realized by the gas and liquid, water is released in fine water droplets.
The venturi scrubber itself has a low volume. The dimensions of the installation are primarily determined by the droplet separator, which can be a few times larger than the scrubber. Venturi scrubbers can be used to remove small particles from a gas stream. However, they can also be used for larger particles, though energy use is relatively high in such cases. Teral-aerotech at very high pressure drops, some types of dust cannot be separated. In some venturi it is possible to vary the width of the throat section, thus allowing the separator to be adjusted for varying flow volumes thus retaining a high yield.
Teral-aerotech Venturi Scrubbers, are effective at removing particulate from exhaust with high efficiency. Venturi scrubbers have several advantages compared to other dust collection equipment. Venturi scrubber are able to handle gas streams that contain moisture are high temperature, the overall size of the equipment is typically smaller, and they have the potential to remove pollutant gas at the same time as the particulate.
Venturi Scrubber Applications
Venturi scrubber high quality design and construction also incorporate self cleaning features to maintain high on-stream performance. Some of the more common industrial applications of venturi scrubbers include Corn Processing Facilities, Food Manufacturing, Machining and Grinding exhaust, Fiberglass and Composite Industries, Utility Boilers, Foundries and Metal Finishing Operations.
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. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers.
