Description
Technical field
The utility model relates to a kind of solid granule pipe-line transportation system, relates in particular to the elutriator in this system.
Background technology
In industries such as petrochemical industry, electric power, grain, coal, semi-finished product and finished product are sent to packing after granulation, section, often use a kind of solid granule pipe-line transportation system, promptly so-called Pneumatic conveyer.Elutriator (also have and be referred to as elutriator) is a gather dust visual plant of part of tail gas in the air-transport system, and it is the capital equipment of pure this quality index of granular material that is transferred of influence; Also be to influence air-transport system exhaust emissions dust-laden capital equipment whether up to standard.
When solid granule was carried in the pipeline of air-transport system, particularly low for hardness, fragility, frangible material carried out dilute phase when carrying, and when perhaps long distance is carried, can produce particle, dust, filament.If particle, dust, filament and finished product are not separated, will influence end product quality.These particles, dust, filament take in the tail gas and emit, and then the exhaust emissions dustiness just can not satisfy environmental requirement.
The applicant is seen following table for details to the actual measurement of Pneumatic conveyer process and the statistics of the industry of part petrochemical industry vistanex product:
| Dilute phase is carried | Close conveying mutually | |||
| The polyester kind | Wear rate ppm/100m | Wearer | Wear rate ppm/100m | Wearer |
| The HDPE particle | 200~300 | Dust, fragment, |
15~40 | Dust |
| The LDPE particle | 300~500 | Dust, silk | 30~60 | Dust, fine hair |
| The LLDPE particle | 300~600 | Dust, silk | 30~70 | Dust |
| The PP particle | 200~300 | Dust, fragment, silk | 20~50 | Dust |
| The PS particle | 200~300 | Dust | 30~50 | Dust |
| The PA particle | 200~400 | Dust, silk | 20~50 | Dust |
| The PET particle | 100~300 | Dust, silk | 10~40 | Dust |
How designing an energy is the problem that the technical staff will solve with the elutriator that particle, dust, filament do not take in the tail gas.
Summary of the invention
The utility model technical issues that need to address have provided a kind of elutriator efficiently, are intended to solve the above problems
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: body; Described upper part of body is a column that comprises upper inlet; In the bottom of column is a up big and down small cylindrical shell; In the bottom of cylindrical shell is a drum type cylindrical shell that is included in the lower end cone; In body, also settle a center mozzle; A dusty gas outlet is arranged on cylindrical shell side side; There is a washing gas import at other place in the side of the upper end of drum type cylindrical shell.
Compared with prior art, the beneficial effects of the utility model are: the dustiness after the elutriation of reduction finished product; After improving an elutriation of finished product, particle can be at broken or generation dust in the elutriation process.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 adopts the utility model dust, filament and particle path schematic diagram; Among the figure: dust 100, filament 101, particle 102;
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: body 1; The top of described body 1 is a column 11 that comprises upper inlet 110; In the bottom of column 11 are up big and down small cylindrical shells 12; Be one in the bottom of cylindrical shell 12 and comprise the drum type cylindrical shell 13 of cone bottom; In body 1, also settle a center mozzle 14; A dusty gas outlet 15 is arranged on cylindrical shell 12 sides side; There is a washing gas import 16 at other place in the side of the upper end of drum type cylindrical shell 13;
The diameter of described cylindrical shell 12 is greater than the diameter of column 11; The diameter of drum type cylindrical shell 13 is greater than the diameter of cylindrical shell 12.
In common gravity elutriator, raw particle enters in the gas stream from top to bottom, the direction of this gas stream makes progress, its speed is slightly less than the decrease speed of particle, little light particle, their decrease speed is littler than the speed of gas, so they are separated removing in bag filter or cyclone separator.
Particle bigger, that weigh can fall along the opposite direction of gas.The falling speed of averaged particles be 5m/s. this be the relative velocity that acts on particle surface.This underspeed sticks to the dust granules of particle surface with " blowing off ".The VELOCITY DISTRIBUTION of gas is the midrange speed maximum in pipeline, and particle is more little the closer to tube wall speed, and speed is zero when arriving tube wall.So the dust granules and the particle that move to tube wall fall together.
The gravity elutriator volume that accuracy is high is big, because its solid-gas ratio is no more than 0.5kg particle/1m
3Gas is so it needs very high air velocity just can obtain desirable dust removing effects.
Gas accelerating sections in the utility model, all particles, dust all accelerates to the speed c of 35m/s with reeling off raw silk from cocoons, and this speed is down, and gas leaves bag filter or efficient cyclone separator that elutriator enters the downstream with 180 degree break-ins then.
All enter the particle of elutriator, because the principle of inertia can not done the break-ins of 180 degree together with gas, they can enter into following braking section and speed is that the purge gas of 15m/s converges.
As seen from Figure 2: dust is accelerated under the effect of purge gas and is purged away with reeling off raw silk from cocoons, and has only the heavier particle with cleaning could pass through braking section, enters following feed bin.Relative gas velocity around the particle is 35m/s+15m/s=50m/s, and this speed wants the relative gas velocity of force of gravity elutriator high 10 times.Because square being directly proportional of the relative velocity of the towing tension of gas and it is so the power that acts on the dust granules wants the power of force of gravity elutriator generation high 100 times.Therefore, adopt the utility model can reach very high cleannes.
The utility model adopts metal structure, is many with stainless steel and aluminium alloy especially.
Traditional design is that side is advanced, and takes bigger diameter, to scheme to fall low gas velocity, is convenient to sedimentation.The utility model is designed to upper inlet, and its diameter can form higher gas speed.Pipeline is longer slightly than traditional design, is unlikely to just to produce in inlet tube turbulent flow.
Middle part drum type cylindrical shell: traditional design is symmetrical up and down, and takes less diameter, to scheme improving gas speed, is convenient to discharging.The utility model is designed to asymmetric up and down, and the bottom is shunk and wanted mild, can not be the same with top.And take the diameter bigger than inlet pipeline.Because air velocity is excessive, can increase the air-flow pressure drop greatly herein.
Bottom drum type cylindrical shell: the utility model is designed to asymmetric up and down, and the bottom is shunk and wanted mild, can not be the same with top.The design of its barrel diameter must be able to form the washing air-flow greater than 15m/s.
The center mozzle makes the air-flow that enters elutriator can form ring-like uniform state.
The tangential inlet of washing air-flow also is essential.
