Abstract:

One of the main sources of dust-bearing emissions in the metallurgical industry is the sintering machine. An acoustic field was formed during the initial stage of heat treatment of a sintering-machine charge by using an acoustic radiator in the form of a Hartmann whistle installed in the vacuum chambers of the machine. The acoustic field covers 15-20\% of the sintering area and has an acoustic power of 1.0-1.2 kW/m(2). Use of the field has increased the productivity of the sintering machine 3.2-8.3\%, reduced the amount of carbon monoxide formed by 26.7-33.4\%, and reduced the entrainment of dust by the gas by 29.2-36.2\%. When an acoustic field with a power of 0.3-0.4 W/m(3) is created inside the flue-gas collection main, dust emissions can be cut by at least 20-25\% of the original value.
