Heavy oil dehydration instrument

The utility model discloses a thick oil dehydration instrument which comprises a dehydration reaction kettle, a stirrer and a three-dimensional electric shock device, the stirrer is provided with at least two stirring blades and is inserted into the dehydration reaction kettle, so that all the stirring blades are arranged in the dehydration reaction kettle; the three-dimensional electric shock device is provided with at least two electric shock layers in the dehydration reaction kettle. The device provided by the utility model has the characteristics that stirring can be carried out after high-voltage electric shock breakdown demulsification is carried out in the heavy oil dehydration process, the experiment time is shortened, the experiment energy consumption is reduced, meanwhile, water drops are gathered through stirring after high-voltage electric shock demulsification, the volatilization of light components at high temperature can be avoided, the property of the dehydrated heavy oil is not changed, and t
