Results are presented for the development and testing of mock-up and experimental-industrial prototypes of an annular vibratory absorber with a resonance type of vibration exciter, which is intended for the deep cleaning of gases emitted during chemico-metallurgical productions. Optimal design and regime operating parameters of the equipment, which ensure high entrapment efficiency of toxic gaseous impurities at increased gas flows, are obtained.Absorption column vessels with a vibratory drive, which are under development by the VNIINM, are intended for the removal of toxic and corrosion-inducing gaseous impurities from effluent gases by a liquid absorbent [1][2][3][4]. The effectiveness of various modifications of vibratory-column absorbers during entrapment, for example, of acidic gaseous impurities and iodine approaches 100%, and is virtually independent of their initial concentration in the effluent gases [5].Resonance electromagnetic vibration exciters, which are distinguished by economy and ease of maintenance, and the possibility of on-going smooth regulation of vibration intensity, are used to drive the vibratory mixers (mixer). The relatively low amplitude (no more than 2.5 mm at a frequency of 50 Hz) of the harmonic vibrations generated permit ready sealing of the vessel housing at the point where the vibratory mixer is introduced; this assumes major significance during operation with radioactive materials, since ecological safety and reliability of the equipment are ensured during operation.Column vibratory absorbers are used in gas-cleaning units of chemico-metallurgical production operations carried out by the Mayak Association; nuclear-safety requirements (vessel diameter of no more than 0.12 m, output of 4 m 3 /h with a specific gas load of 0.01 m 3 ·sec/m 2 ), however, restrict their use only to local cleaning of separate gas flows containing toxic impurities. In that case, cleaning of an overall gas flow, the rate of which reaches 250-300 m 3 /h, by use of several tens of safe column vibratory absorbers operating in parallel is inexpedient, since significant production areas and major expenditures for fabrication of the vessels themselves are required, the gas-cleaning system is also appreciably complicated, and labor outlays for its maintenance are increased.A vibratory absorber with an annular (in cross section) effective zone, the internal wall of which serves as a vibratory mixer, has been developed to improve the output of a single vessel and replace the inadequately effective and unsafe-to-operate equipment in the gas-cleaning units [6].
