Description
Technical field
The present invention relates to a kind of device of magnetic-particle in rotating excitation field gas recovery, belong to gas solid separation field.
Background technology
Isolation technics and magnetic separator according to modern existing more than 50 years developing history, its by magnetic field force effect, to magnetic conductivity
Different materials are separated, and ore dressing industry is applied to earliest.After the industrial magnetic separator of American invention, Magneto separate starts with machinery
Advised in field of the form of equipment successively in raw materials such as coal desulfurization, glass and cement in addition to the ore dressings such as iron, kaolin purification
Modelling application.Magnetic separation method majority was applied to water treatment industry in recent years, and Magneto separate utilizes the magnetic of impurity particle in waste water
Separated, for non magnetic or weak magnetic particle in water, can make them that there is magnetic using magnetic inoculation technique, by waste water
In magnetic suspended solid separate, so as to reach the purpose of purified water.Research for water process has preferably been sent out
Exhibition, but in terms of industrial cigarette (useless) gas Study on purification, research does not seldom also study foundation clearly.With social economy
Develop rapidly, the process of industrialization of China is also increasingly faster, while industrialized production brings economic development to us, great Liang Gong
The discharge of industry waste water, waste gas, serious threat is also brought to the natural environment that we depend on for existence.
Show that industrial wastewater discharge total amount is 716.2 ten thousand tons, the row of cigarette (powder) dirt according to national environmental statistics publication in 2015
Total amount is put for 1740.8 ten thousand tons, wherein industrial cigarette (powder) dirt discharge capacity is 1456.1 ten thousand tons.Industrial fumes contain substantial amounts of harmful
Or can recycle fine particles, if these particulates, which can not be handled and reclaimed in time, will cause serious environmental pollution and original
The waste of material, but industrial smoke progressively endangers environment, frequently haze weather has beaten alarm bell to us, administers industry
Flue gas is extremely urgent.For cigarette (useless) gas dedusting, traditional processing method such as generally existing efficiency such as particle precipitation method is relatively low
The bad situation with effect.China University of Geosciences's soup is cooked of HGMS technology to the separation of flyash ingredient up to detecing et al.
Experimental study, as a result shows：Magnetic separation technique can be effectively separated to three class bases in flue dust.This explanation Magneto separate
Technology has its unique advantage in cigarette (useless) gas.In addition, in industrial and life, there are a variety of gas containing magnetisable material
Flue gas in body, such as vehicle exhaust containing little metallic particles, containing the porous magnetic medium for being adsorbed with PM2.5~10, contain
Be magnetic particle industrial fluids, be mixed into flue-gas and be used to adsorb wherein Hg magnetic bead etc..
In gas solid separation, common separate mode has：Gravitational settling, inertia force separation, intercepts and separates, charged separation,
Gravitational settling is different from fluid density using particle, and the generation relative motion of particle and fluid is so as to reach point under gravity
From process, gravitational settling is characterized in that sinking speed is small, so the sedimentation time needed is long, gas flow very big situation
It is lower, it is necessary to which dust-settling compartment large area drawout in the plane, floor space is very big；According to multilayer architecture, then reclaim
Solid particle is difficult to continuous collect and discharged again, and efficiency of dust collection is very low.
Centrifugation is also one kind of sedimentation separation, and its principle is different from fluid density using particle, in centrifugal force
The lower particle of effect produces relative motion with fluid and separated, and the advantage of centrifugation is square of centrifugal force and fluid tangential velocity
The sinking speed of particle in a fluid can be greatly improved by being directly proportional, therefore improving linear speed, both improved separating effect, reduced again
Equipment volume, but be not particularly suited for the separation of carried magnetic porous media, centrifugal force can make carried magnetic porous media with
Sharp impacts occur for the wall of separator, and the fine particle that impact force can trap magnetic porous medium departs from, do not reached
The effect of clean flue gas.
Turnover suddenly occurs during air-flow cut-through thing for inertia separator, thing of being placed obstacles on the path that gas flows,
Particle or drop are just impinged upon on barrier and are captured down, and subject matter is, only by inertia force, there is class during its deflecting
Like the separation extreme of cyclone separator, and its deflecting process is short, therefore separating capacity is much smaller than cyclone separator, along with need
Want high linear speed to provide enough inertia force, therefore be difficult to avoid that particle takes up problem again, therefore separative efficiency is not high, only compares dust-settling compartment
It is slightly good, it can only typically be used as coarse separator.
Charged separation is the band Charged particle in gas, particle is separated with gas in the presence of electric field force.But
It is carried magnetic porous media without charged, therefore the technology can not be separated with this.And charged separation needs rapping, rapping meeting
Reentrainment of dust is caused, and to standard far can not be reached containing the larger occasion trapping of magnetic porous medium amount；In addition it is whole
Dust arrester needs high-voltage transforming and rectifying installation, and investment and operating cost are all higher.
