Study on fluid-structure interaction vibration characteristics of absorber feed tank based on micro vibration monitoring

Absorber feed tank (AFT tower) is a kind of reinforced concrete structure supported steel tank. It composite used for desulfurization and cleaning in power industry. A large amount slurry sumped the tank, oxidation air blown into through pipe to impact surface, then agitator vibrates disturbs The has obvious vibration daily operation, which not conducive safety structure, but also brings greater psychological burden staff. Therefore, field monitoring numerical simulation analysis are carried out AFT tower. investigation tower out. video local monitor tower, corresponding laws explored. simplified method this proposed. model established with aid fluid coupling function ADINA finite element software study characteristics results show that motion trajectory can be determined quickly by monitoring. demonstrate effect mixer main factor structural vibration, blowing wind intensifies response, resulting different degrees damage infilled wall between columns structure. By comparing results, reliability verified, provides reference analyzing mechanism reinforcement design
