摘要
Abstract
In order to solve problems in the coke powder removal of oil coke delayed coking process,an ultrasonic assisted backwashing test bench is designed.First of all,we use the filter to filter the foul oil,and then wash the filter core by the ultrasonic auxiliary backwash.The cleaning effect of the filter core is judged by the method to measure the pressure difference of the filter core.At the same time we analyze the influence of the recoil time,the ultrasonic power density,the effects of ultrasound time and other parameters on the filter cleaning effect.The tests show that:the ultrasonic assisted backwashing filtering method can significantly reduce the filter pressure difference,and compared to the recoil liquid method without ultrasonic assisted,the filter washing cleaning effect is significantly improved.When the power density is 1.6 W/cm2,the ultrasonic effect is 15 min,and the recoil liquid is 15 min,the cleaning effect is more suitable.关键词
