Problems solved by technology

[0003] Patent document CN103803766A provides a low-temperature oil sludge demulsifier, which achieves a higher oil recovery rate, but the demulsification stirring time is longer; patent document CN109020107A reports a three-phase separator for oil sludge demulsification, but does not provide relevant test data; Patent document CN108975646A reports an oil sludge demulsifier with an oil recovery rate of 88.45-92.57%. The above-mentioned patents do not pay attention to the index of dehydration rate; at the same time, it can be seen that there is a demulsification time in the prior art Shortcomings of long life and low oil recovery rate
