Sieve array and precipitator device and method of treating exhaust

Abstract

A vibrating wet precipitator is designed to remove particulates from particulate-laden hot gas. The precipitator includes an array of vertical wet cords stretched within a duct. The cords are tuned to vibrate due to the gas flow by controlling key parameters such as gas flow, velocity, cord length and diameter so that particulate collection and heat transfer efficiency are maximized. The cords are part of sieves. A plurality of these sieves are arranged to define a plurality of gaps, through which the exhaust flows. The sieves and thus the cords are space so that a vortex from a first cord affects an adjacent cord and subsequently cord. The particles are then absorbed in liquid, which can be passed through a heat exchanger filtered and subsequently reused. Preferably the cord arrangement is designed to allow the cords to vibrate at high frequencies, typically 10 to 100 Hz, to maximize particulate collection.
