Demulsifier filler is offered between mouthful on barrel, is dosing room in barrel, dosing room is connected with demulsifier filler.
The present invention, which further improves, to be：
Dosing room is around barrel to the radially distributed several spray tubes in center.
A diameter of 8mm of spray tube, length 24mm, and surface is evenly distributed with the circular hole of several a diameter of 0.8mm.
The nozzle of spray tube is provided with seal cap.
The quantity of spray tube is 8.
Mixing chamber is the hollow cylinder perpendicular to mixing drum.
Several gaps are offered on hollow cylinder.
The length of cylinder is 154mm, a diameter of 137mm, wall thickness 7.1mm.
The width in gap is 3mm, length 110mm.
Gap is slot, offers six groups altogether；Wherein, it is made of 5 slots for four groups；Two groups are made of 16 slots.
Compared with prior art, the invention has the advantages that：
Cylindrical body of the present invention by flanged joint in fluid line is equipped with ring at the feeder connection of mixer
Shape dosing center distributor chamber distributes chamber interior walls around the dosing center and extends to body central and in uniformly distributed more and dosing
The dosing branch pipe equipped with medicine outlet hole of heart distributor chamber connection, dosing branch pipe are directed toward body central perpendicular to the liquid direction of coming of tube body；
Dosing center distributor chamber be connected with connection medicine source for medicine manifold；Dosing branch pipe is uniformly distributed medicine feeding hole, while nozzle is stamped sealing
Cap.Mixing chamber is made of drum-shaped band slot steel pipe, and the present apparatus may be implemented demulsifier and is sufficiently mixed with crude oil emulsion, simultaneously
The crude oil emulsion caused by the factors such as pressure drop is low emulsifies the problems such as serious when entering centralized processing device by reducing, and passes through
Field test proves, using can effectively reduce by 20% or more demulsifier dosage after the medicine mixing device.
