Examination of Heat Exchange in a Porous Dust-Gas Catcher With a Ring-Pipe Sprayer

Abstract

Nozzle-free capillary-porous dust and gas trap with foam generating and defoaming structures was developed and studied. Foam flow is generated by dusty gas, micro and ultra microscopic particles, which are especially dangerous for human body, are cleaned. Stability of liquid film in the porous structure during supply of foam-forming liquid by a spray in the form of a tubular ring, was determined. Foam generating and defoaming structures have been optimized, due to this material consumption and dimensions are reduced by 2-2.5 times, hydraulic resistance - by dozens of times (up to one hundred times), and gas-dynamic - by up to two times.
