Embodiment 1
The utility model people of the application has found afterwards after extensive and in-depth study, particle is washed, traditional machinery
Washing methods predominantly impacts injection reactor, stirring container and ultrasonic washing method.But all there are many drawbacks in three kinds of methods,
Such as stirring container, required space is big, has larger noise and tank center is also easy to produce the temperature difference with material near tank skin, influence to wash
Effect.For another example supersound washing device, energy consumption is relatively high, cannot meet a large amount of particles while wash, and noise reduction packing material
Once damage, noise pollution are serious.And use just, the method that the particles collision and cavitation that reversed eddy flow causes organically combine can
To reach good washing effect, and it is compact-sized, required space is small, and low energy consumption, and detersive efficiency is high, thus is most applicable in
Property.Effect finds that the utility model is accomplished based on above.
As shown in Figure 1, being 1 structural schematic diagram of the embodiments of the present invention, which includes mainly：2 is trans-
Dextrorotation washing unit；3 n- derotation washing units；4 Venturi tubes.Certain petrochemical plant uses material inlet flow for 380m3/ h, text
The a diameter of 0.25m of venturi (D).It is analyzed according to treating capacity, using two n- derotations, four tubular types of two trans- dextrorotation washing units
Grain wash mill.Material flows into washing pipeline by import 1, particle to be washed with cleaning solution.Therewith, solidliquid mixture enters
Trans- dextrorotation washing unit 2, n- derotation washing unit 3.Pass through making for trans- dextrorotation washing unit 2 and n- derotation washing unit 3
Rotation act on, the liquid form of solidliquid mixture becomes rotational flow from bottom horizontal flow sheet, under cyclonic action, cleaning solution with to be washed
Grain comes into full contact with, and the petroleum hydrocarbons in solid particle preliminarily form emulsification state with cleaning solution.Pass through dextrorotation in washing unit
Fin and derotation unit are arranged alternately, and particle to be washed constantly changes spin with cleaning solution and flows to, and improves detersive efficiency.
It is different with eddy flow flowing rotation direction caused by derotation fin by the dextrorotation fins of adjacent tubes simultaneously, particle to be washed with wait washing
With cleaning solution severe friction occurs at washing pipeline axis for particle, particle to be washed, and collides.Due between particle and particle,
Tangential force coupling caused by frictional force and eddy flow between grain and cleaning solution, the elution effect of petroleum hydrocarbons increase
By force.Then, solidliquid mixture enters the contraction section of Venturi tube 4.By the cavitation of Venturi tube 4, vacuole rapidly generates,
It expands and crumbles and fall, form shock wave and high-speed micro-jet in a liquid, reduce adhesive force of the petroleum substance to solid particle.And text
4 unique reducing and expansion structure of venturi makes pressure reduction, and according to Bernoulli equation, flow velocity increases, and accelerates flowing to reach
Effect.The increase of speed can also be such that Reynolds number increases, and further increase the degree of turbulent flow, strengthen solid particle washing effect.Through
It crosses the cleaning solution of the reducing and expansion section of Venturi tube 4 and solid particle reserves wash mill, complete washing.It is washed by the multitube particle
The washing for washing device, for diameter>The oil-containing solids particle of 2mm, goes oil cut rate to reach 90% or more.For a diameter of 0.05-2mm
Oil-containing solids particle, eluting rate reaches 85% or more.Illustrate the wash mill will just, collision effect that reversed eddy flow causes,
The cavitation of radial spin, deflecting spin and Venturi tube organically combines, to the elution efficiency of petroleum hydrocarbons
It is higher, there is good applicability.
