Description
Technical field
The present invention relates to the gas solid separation technical field, be specifically related to a kind of gas-solid centrifugation and exhaust integrated machine, carry two big functions to accomplish gas solid separation and gas, improve the separative efficiency of solid ultra-fine grain (particle diameter≤10 μ m) with an equipment.Be mainly used in the dust pelletizing system of industries such as oil, chemical industry, medicine, smelting iron and steel, non-ferrous metal metallurgy, cement plant, thermoelectricity boiler, grain processing plant, coking plant.
Background technology
The gas solid separation of dusty gas is the main technique flow process of industries such as oil, chemical industry, medicine, mine, metallurgy, cement, thermoelectricity, grain processing.Reducing the pollution of all types of industries dust to atmosphere, is the environmental protection problem that the current whole world is paid attention to.
The gas solid separation of dusty gas is divided with regard to big aspect has two types, and one type is dry method dust, and one type is wet dedusting.Though some hydrofilters are high to fine grain separative efficiency, bring water to pollute and the wasting of resources, because available raw material behind most dust collection; Just lost using value after the immersion; Be water insensitive material, reclaim and also want dry, increase energy consumption.In addition in the winter of cold district, also to heat and be incubated dust pelletizing system, increase power consumption.So occasion is as far as possible without wet dedusting mostly.At present, dry method dust is the most frequently used dedusting method.Dry dust removal equipment mainly contains cyclone separator, electrostatic precipitator, sack cleaner and all kinds of inertial dust separator.Wherein to be dust-contained airflow get into the cylindrical shell shape of spinning along tangent line to the basic principle of cyclone separator rotatablely moves, and under centrifugal action, grit separated.As shown in Figure 1.Simple in structure because of it, reliable, 100 for many years, in industry, uses the most extensive.The shortcoming of cyclone separator is very low to the separative efficiency of fine particle.Introduce according to list of references [1] table 1-18, when the solid grain size in the dusty gas >=50 μ m, the separative efficiency of cyclone separator can reach 94%; But when solid grain size in the dusty gas is 5 μ m; Separative efficiency only 27%, when particle diameter was 1 μ m, separative efficiency was merely 8%.According to list of references [1] table 1-21 regulation, when the solid grain size in the dusty gas≤10 μ m, must adopt sack cleaner or electrostatic precipitator.During the velocity perturbation of cyclone dust collectors inlet air flow, bigger in addition to the separative efficiency influence.
The basic principle of sack cleaner is to capture dust with the fibroid filter bag.The separative efficiency of sack cleaner is high, be solid grain size in the gas be 1 μ m, the separative efficiency of sack cleaner is also up to 99%
[1], it is the highest deduster of separative efficiency in the present dry collector.But the average filtration speed of sack cleaner is that (0.017～0.02m/s), so when the flow of dusty gas was big, the filtering surface of fiber was very big, causes equipment huge, investment is high, and can only be applicable to the occasion of gas temperature≤250 ℃ for 1～1.2m/min
[2], in the allowable temperature scope, when being higher than 80 ℃, temperature is high more, and the price of filter pocket material is high more.Except that sack cleaner cost height, operating cost is also higher, because of filter bag wearing and tearing and grit fouling obstruction, needs often to change filter bag.
The basic principle of electrostatic precipitator is under the high voltage electric field effect, makes the particle particle in the dust-contained airflow charged, and is attracted, captures.The separative efficiency of electrostatic precipitator is high, is that the separative efficiency of 5 μ m is 99% for particle diameter
[1], be that the separative efficiency of 1 μ m is 86% to particle diameter
[1]The average flow velocity of dusty gas is 0.4～1.8m/s in electrostatic precipitator
[1]So area of passage is also bigger.Because high-tension system is arranged, its structure is more complicated, and the one-time investment expense and the operation and maintenance cost of electrostatic precipitator are also higher.
Can in dusty gas, solid grain size be when proportion is higher in 1～10 mu m range, work out that the low deduster of a kind of cost replaces or part replaces sack cleaner and electrostatic precipitator, and this is pursuing one's goal of present gas solid separation researcher.
Since O.Morse in 1886 had obtained first patent of cyclone separator, the technology of cyclone separator was constantly developed always, to main two aspects, the one, theoretical research, the one, the experimental study of dividing of its research.For the separative efficiency and minimizing flow losses that improve cyclone separator, experimental study is divided into two aspects again, and the one, each geometric parameter and the inlet velocity of optimization cyclone separator; The one, the version of change cyclone separator.This two aspect has all obtained obvious effects.Effect is preferably U.S. Pat 2941621 aspect parameters optimization, this patent be with the reduced of separation chamber's cylinder to 80mm, improved separative efficiency, for the catalyst dust of particle diameter≤10 μ m separating effect has preferably been arranged.In order to satisfy big flow, more a plurality of separate unit tubule cyclone separators are made the array of parallel connection.Because tubule quantity is more, cause equipment huge, complex structure is made difficulty, and it is uneven to be prone to produce assignment of traffic between each single tube, and dust problem such as play a reversed role causes separative efficiency to reduce.When charge flow rate fluctuation was big, separative efficiency was lower especially, and time is everlasting on the ground far away of hundreds of rice around the refinery catalytic cracking unit, and naked eyes just can be seen the catalyst dust that one deck is white.Because the separating force of cyclone separator depends on the diameter of dusty gas inlet velocity and separation chamber, so the fluctuation of inlet gas flow is the inevitable shortcoming of cyclone separator to the influence of separative efficiency.
Changing version has certain innovation property, and patent documentation CN85200870U makes cyclone separator into several by an air inlet exactly, and concrete structure is seen shown in Figure 2.In this patent documentation the air velocity of each air inlet is brought up to 100m/s, improve 4～5 times than the speed of former cyclone separator air inlet, this improvement has improved separative efficiency.But import department's flow resistance can increase, and air velocity only can reach 100m/s in import department, and after air-flow got into the annular release chamber, air velocity can descend rapidly, can not in whole volute chamber, keep high centrifugal acceleration always.The big minor swing of air velocity of import department can influence separative efficiency simultaneously.
Increase centrifugal force and be the effective way that improves the gas-solid separator separative efficiency.Chinese patent document ZL02103986.0,02103989.5 and CN2766964Y made effective achievement in this respect; Their common characteristic is in being similar to the circular cylindrical shell of cyclone separator, to adorn the pinwheel of a rotation, like the described pinwheel structure of CN2766964Y: " pinwheel 3 by U font needle-like seedling radially evenly dense arrangement layering stacked combination on wheel hub, form.There is at least one pinwheel to be fixed on the turning cylinder." its structural principle is as shown in Figure 3, pinwheel 3 is to do dead axle by driven by motor to rotate among the figure.The flow direction of dusty gas can be the tangential with pinwheel and flow (or helical flow), also can be axial flow.The effect of pinwheel be with gas in solid particle collide, make particle obtain higher centrifugal force, thereby improve the separative efficiency of ultra-fine grain.According to this patent documentation statement, be the particle of 2 μ m to particle diameter, separative efficiency can improve 2 times.This be one greatly the progress.Obviously, the main solid particles of this pinwheel additional in the patent documentation increases rotation function, improves separative efficiency.This improvement has increased by a cover rotor, added energy consumption, and the entering of dusty gas and discharge must provide kinetic energy by blower fan.
