The gas being dissolved in liquid can be escaped, and form gas-liquid or gas-liquid-solid multiphase flow, after high-speed multiphase flow body enters tube of pressure-stabilizing 2, by
In the presence for having fluid column, gas-liquid mixture produces friction with fluid column, so as to further by kinetic energy dissipation, and due to fluid density it is remote
More than gas density, gas will not be shot through fluid column so that impact flow of the material in tube of pressure-stabilizing 2 is less.This utility model reality
A kind of first supercritical processing technique dropping equipment of example offer is applied, mainly by the pressure changed to make material of 1 bore of nozzle
Reduce, thus material can produce larger impact and abrasion in the runner 13 of nozzle 1 during flowing, but due to nozzle 1 it is detachable
Be connected on tube of pressure-stabilizing, thus individually nozzle 1 can be changed, is changed relatively simple.Meanwhile, nozzle 1 can adopt mould
Produced in batches, the production cost of single-nozzle is not high, this causes the first supercritical processing technique dropping equipment when in use
Cost it is relatively low.
To make the pressure drop that material is produced when through nozzle 1 larger, as shown in Figures 2 and 3, runner 13 is included along material
The secondary fluid course 131 of multistage connection that sets gradually of flow direction, and the diameter of multistage secondary fluid course 131 successively decreases step by step, the closer to
The diameter of the secondary fluid course 131 at material outlet 12 is less.Material when the intersection of adjacent two-stage secondary fluid course 131 is flowed to, by
In the unexpected reduction of secondary fluid course diameter, the resistance moment increase produced to material, so that material produces pressure drop, there is energy
Loss.
To reduce the size of nozzle 1, as shown in Figures 2 and 3, secondary fluid course 131 is straight barrel type secondary fluid course.By multistage connection
After secondary fluid course 131 is set to straight barrel type secondary fluid course, flowing velocity of the material in same one-level secondary fluid course is constant, but material is in flowing
During to next stage secondary fluid course, can be due to the unexpected reduction of secondary fluid course diameter, the resistance moment increase produced to material is produced larger
Pressure drop so that there is larger energy loss in material.And if the secondary fluid course 131 in runner 13 is set to round table-like structure
Secondary fluid course when, used in the runner 13 compared to equal length for straight barrel type secondary fluid course, material round table-like structure time
In runner during flowing, as the diameter of the secondary fluid course of round table-like structure persistently reduces, this causes material energy conversion in flowing
Process is more lasting, and energy loss is less, thus, to reach same pressure drop effect, using the nozzle 1 of straight barrel type secondary fluid course
In its size on Flow of Goods and Materials direction, much smaller than the secondary fluid course using round table-like structure nozzle at which along Flow of Goods and Materials side
Size upwards.Therefore, version in secondary fluid course 131 is different, but reach in the nozzle 1 of uniform pressure drop, by secondary fluid course
131 are set to size minimum of the nozzle 1 of straight barrel type secondary fluid course at which on Flow of Goods and Materials direction.
For ease of processing, as shown in Figures 2 and 3, the runner 13 in nozzle 1 is set to into two-stage straight barrel type secondary fluid course preferably
The form of connection.Now the runner 13 of nozzle 1 can be in the form of integrally casting in processing, it would however also be possible to employ bore mode,
Difficulty of processing is low.
As material flow is fast and contains solid particle, thus material in the nozzle 1 during flowing to the abrasion of runner 13 compared with
Greatly, to delay the abrasion of runner 13, on the inwall of runner 13, it is provided with wearing layer.Wearing layer preferably adopt diamond coatings or
Coat of silicon carbide.Wearability refers to the resistivity that coating is acted on to friction mechanism, actually the hardness of coating, adhesive force and
The embodiment of cohesiveness comprehensive effect, in the case of condition identical, wearability of the coating abrasion performance better than metal material, because wear-resisting
Coating has viscoelastic effect, row buffering, absorption is entered during Flow of Goods and Materials to the energy that 13 inwall of runner is produced or can discharge, from
And extend the service life of runner 13.It should be noted that the wear-resistant coating in runner 13 can be tungsten carbide coating, ceramics
Other high-abrasive materials such as coating spray the coating to be formed, and this utility model is not construed as limiting to this.
Alternatively, nozzle 1 is directly made using the high-abrasive material such as tungsten carbide or ceramics, due to the small volume of nozzle 1, because
When this is sprayed at high-abrasive material on runner 13, the operation difficulty of spraying coating process is higher, and directly makes spray using high-abrasive material
During mouth 1, due to the small volume of nozzle 1, the consumption thus for high-abrasive material is little, therefore cost will not increase, and technique
Difficulty is relatively low.
A variety of modes are removably connected between nozzle 1 and tube of pressure-stabilizing 2, for example, are usable on the outer wall of nozzle 1
Be threaded, nozzle 1 screwed into the mode to the import 21 of tube of pressure-stabilizing 2, or using flange group 3 by nozzle 1 removably

Place, flange group 3 include the upper flange 31 being detachably connected and lower flange 32, the centre bore 311 of upper flange 31 and entering for tube of pressure-stabilizing 2
Mouthfuls 21 connect, and flange 14 is held between upper flange 31 and lower flange 32, and nozzle 1 is provided with one end of material outlet 12 and is located at
In the centre bore 311 of upper flange 31 and towards tube of pressure-stabilizing 2.
Clamp for ease of upper flange 31 and lower flange 32, flange group 3 also include being arranged at upper flange 31 and lower flange 32 it
Between Gask-O-Seal, the diameter of the internal diameter of Gask-O-Seal more than flange 14, so that Gask-O-Seal can be arranged at method
Between blue 31 and lower flange 32；And the thickness of Gask-O-Seal more than flange 14 thickness, and the thickness of Gask-O-Seal with it is convex
The span of the difference between the thickness of edge 14 is 0.1mm～0.5mm, when the thickness of the thickness and flange 14 of Gask-O-Seal
Between difference when being less than 0.1mm, upper flange 31 and lower flange 32 in clamping process, for the squeezing action of Gask-O-Seal
It is less, it is unfavorable for the clearance seal between upper flange 31 and lower flange 32；And work as the thickness and flange 14 of Gask-O-Seal
When difference between thickness is more than 0.5mm, as the thickness of Gask-O-Seal is thicker, upper flange 31 and lower flange 32 were being clamped
Cheng Zhong, it is impossible to effectively nozzle 1 is clamped, nozzle 1 occurs the situation of rocking in use.Therefore, only work as Gask-O-Seal
Thickness and the thickness of flange 14 between difference span be 0.1mm～0.5mm when, guaranteeing upper flange 31 and purgation
Nozzle 1 can be clamped by blue 32 so that when dropping equipment runs, nozzle 1 can keep fixed, and nozzle 1 will not be because of the impact of material
On the premise of producing vibrations or offseting, additionally it is possible to leak in avoiding gap of the material between upper flange 31 and lower flange 32.It is excellent
Select Gask-O-Seal thickness and flange 14 thickness between difference be 0.3mm, now Gask-O-Seal is to 31 He of upper flange
Clearance seal best results between lower flange 32, and it is able to ensure that nozzle 1 is clamped by upper flange 31 and lower flange 32.
When gas content in material is more, as gas flow rate is larger, liquid being centrally formed in tube of pressure-stabilizing 2 can be passed through
Air-flow, liquid material is extruded to liquid film the inwall flowing along tube of pressure-stabilizing 2 are formed at the inwall of tube of pressure-stabilizing 2, and this is existing
As being referred to as annular flow.And the liquid film formed in annular flow is typically relatively thin, this causes constricted flow of the material in tube of pressure-stabilizing 2,
To avoid annular flow is formed in tube of pressure-stabilizing 2, as shown in figure 1, being sequentially provided with multilamellar orifice plate along the flow direction of material in tube of pressure-stabilizing 2
23, orifice plate 23 can be by the airflow crash formed in annular flow into minute bubbles so that cannot form annular flow in tube of pressure-stabilizing 2, it is ensured that
Proper flow of the material in tube of pressure-stabilizing 2.
In the above-described embodiments, on orifice plate 23, the aperture of perforate can be adjusted according to the air content in material, its value
Size is typically between 3mm～20mm.Meanwhile, the percent opening of orifice plate 23 should be between 30%～70%, and percent opening refers to orifice plate
The ratio between all aperture area sums and the imposite area of orifice plate 23 on 23.Percent opening can be badly influenced less than 30%
The flowing of material；And percent opening can cause the intensity decreases of orifice plate 23, the impact that material is produced in flow process more than 70%
It is easily damaged orifice plate 23.
To avoid multilamellar orifice plate 23 excessive to resistance that material is produced, the value model of the spacing between adjacent two layers orifice plate 23
Enclose for 50mm～500mm.Between adjacent two layers orifice plate 23 when being smaller than 50mm, 23 layout of orifice plate is more tight, and material exists
The number of the orifice plate 23 needed guiding through during flowing in tube of pressure-stabilizing 2 is more, and the energy loss of material is larger, can cause whole system pressure
Increase, energy consumption increase.And when the spacing between adjacent two layers orifice plate 23 be more than 500mm when, between adjacent two layers orifice plate 23 between
Away from excessive, it is unfavorable for the blood pressure lowering to material.It is preferred that the spacing between adjacent two layers orifice plate 23 is 50mm.Now material is in tube of pressure-stabilizing
Will not form annular flow in 2, and material to flow through the flow velocity after multilamellar orifice plate 23 moderate, do not interfere with the subsequent treatment of material.
Flow direction of the material in tube of pressure-stabilizing 2 can be horizontal, or longitudinal direction.When the flow direction of material is horizontal stroke
Xiang Shi, the solid particulate matter in material are easily deposited on the bottom of tube of pressure-stabilizing 2 in the presence of its gravity, it is difficult to pushing away in material
Action is flowed out by the outlet 22 of tube of pressure-stabilizing 2 with lower, and this fraction solids granule cannot be introduced into, in subsequent processing device, reducing thing
The conversion ratio of material.Therefore, in order to avoid the problems referred to above, it is preferred that as shown in figure 1, the import 21 of tube of pressure-stabilizing 2 is arranged at tube of pressure-stabilizing
2 bottom, outlet 22 are arranged higher than import 21, and multilamellar orifice plate 23 is set in turn in the import 21 of tube of pressure-stabilizing 2 from the bottom to top and goes out
Between mouth 22.
For the material containing solid particle, material turbulence of the tube of pressure-stabilizing 2 at import 21, solid particle is to steady
The erosive wear of the inwall of pressure cylinder 2 is more serious, thus can be in tube of pressure-stabilizing 2 near spraying abrasion-proof material on the inwall at import 21
Material, such as SiC or diamond.
The complete material of supercritical reaction includes gas, liquid and solid particle, wherein, the gas contained in material is more
For nonhazardous gas such as carbon dioxide, meet the requirement of environmental protection, thus this portion gas can be separated from material and directly
It is emitted in air, as shown in figure 1, dropping equipment also includes the cylinder 4 connected with the outlet 22 of tube of pressure-stabilizing 2, cylinder 4
Internal diameter offers mixture outlet 41, is further opened with gas on cylinder 4 more than the internal diameter of tube of pressure-stabilizing 2 on the side wall of cylinder 4
42 are exported, and gas outlet 42 is arranged higher than mixture outlet 41.Material Jing after the outlet 22 of tube of pressure-stabilizing 2 is flowed in cylinder 4,
Due to cylinder 4 internal diameter more than tube of pressure-stabilizing 2 internal diameter, the flow velocity of liquid material can reduce, under gravity, easily and gas
Body feed separation, after most of gas is escaped from material, Jing gas outlets 42 discharge, the mixture of the separated cylinder of rest materials 4
Outlet 41 carries out subsequent treatment in being sent to next stage processing equipment.
Occur the problem of solids particles precipitate in use to avoid dropping equipment, as shown in figure 1, tube of pressure-stabilizing 2
Bottom offers the import 21 of tube of pressure-stabilizing, and top offers outlet 22；Cylinder 4 is arranged at the top of tube of pressure-stabilizing 2, cylinder 4
