The term wet scrubber describes a variety of devices that remove pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants.
Wet scrubbers can also be used for heat recovery from hot gases by flue-gas condensation. [1] In this mode, termed a condensing scrubber, water from the scrubber drain is circulated through a cooler to the nozzles at the top of the scrubber. The hot gas enters the scrubber at the bottom.
A spray tower (or spray column or spray chamber) is a gas-liquid contactor used to achieve mass and heat transfer between a continuous gas phase (that can contain dispersed solid particles) and a dispersed liquid phase. It consists of an empty cylindrical vessel made of steel or plastic, and nozzles that spray liquid into the vessel.
A venturi scrubber is designed to effectively use the energy from a high-velocity 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 .
Electric scrubbers can make all cleaning tasks look like a breeze in the snippets shown on social media, but don't be fooled. Like with most products, electric scrubbers have their disadvantages.
When very hot gases are to be treated and cleaned using the fluidized bed scrubber technology, they are first passed through a quench chamber, which is usually integrated with the scrubber such that quenching can occur in two steps, using both the inlet quench section and a specially designed sump to maximum effect. The cooled gases are then ...
