Description
Technical field
The present invention relates to a kind of using solid phase particles by the metal smelt of micronic dust circulation absorption in the ultra-fine flue gas of metal smelt
Ultra-fine flue gas solid phase adsorption processing unit and processing method belong to the ultra-fine fume treatment field of metal smelt.
Background technique
CN103553248B, title " heavy metal-polluted acid waste water reclaiming recovery method ", successively the following steps are included: first
The waste acid free settling first that step, smelting process generate removes suspended matter, after refiltering the fine particle in waste acid greater than 5 microns
Into electrodialysis plant；The waste acid is that the flue gas that metal smelt process generates uses wet cleaning technical process in relieving haperacidity
The acid waste water of middle generation, in waste acid h 2 so 4 concentration between 2%-11%, containing copper, lead, mercury, antimony, zinc, arsenic, cadmium,
One or more of indium, nickel, tin, manganese ion and fluorine, chlorine, sulfate radical and hydrogen ion；In second step, electrodialytic process, yin
Ionic membrane uses dianion passability film, and cationic membrane uses monovalent cation passability film, under the action of electric field force,
H in waste acid+Enter sour concentrate, including SO by cationic membrane4 2, monovalence including C, F and dianion then pass through yin
Ionic membrane also enters sour concentrate, and divalent and the heavy metal ion of the above valence state include copper, lead, mercury, antimony, zinc, arsenic, cadmium, indium,
One or more of nickel, tin, manganese ion cannot then be remained in waste acid solution by cationic membrane, including AsO3 3、
AsO4 3High-valence anion inside cannot be also stayed in waste acid solution by anionic membrane, to realize acid and heavy metal ion
Separation, the acidity in waste acid is reduced to H+Concentration is no more than 0.001mol/L；The sour concentrate that third step, second step obtain is used
In recycling relieving haperacidity, obtained low acid heavy metal liquid carries out sulfide precipitation and removes removing heavy metals.Its shortcoming: metal smelting is not suitable for it
Refine the processing of ultra-fine flue gas.
Summary of the invention
Purpose of design: avoiding the shortcoming in background technique, designs a kind of using solid phase particles that metal smelt is ultra-fine
The ultra-fine flue gas solid phase adsorption processing unit of the metal smelt of micronic dust circulation absorption and processing method in flue gas.
Design scheme: in order to realize above-mentioned purpose of design.The present invention is in structure design: 1, gas-solid mixer uses whirlwind
Design of the separator as power source and gas-solid separator is one of technical characteristic of the invention.The purpose of this design is:
Since gas-solid mixer lower-lying metal smelts ultra-fine flue gas and the common necessary channel of porous calcium carbonate particle, in cyclone separator
Under the action of negative-pressure ward, the ultra-fine flue gas of metal smelt and porous calcium carbonate particle enter the process mixed in gas-solid mixer
In, since porous calcium carbonate pellet pores are flourishing, absorption is strong, and the micronic dust in the ultra-fine flue gas of metal smelt can be adsorbed on it by it
On, then when passing through cyclone separator, trace meter is smelted ultra-fine flue gas and is siphoned away by deduster, and adsorbs the porous of micronic dust
Calcium carbonate granule is again introduced into gas-solid mixer lower-lying metal by feeding machanism and smelts ultra-fine flue gas and porous calcium carbonate particle
Common necessary channel, so recycles, until porous calcium carbonate particle saturation (growing up) is discharged afterwards, to realize that physical recycling is gone
Except the purpose of micronic dust in the ultra-fine flue gas of metal smelt.2, using porous calcium carbonate particle as micronic dust in the ultra-fine flue gas of metal smelt
The design of absorbent filter medium, is the second technical feature of the present invention.The purpose of this design is: calcium carbonate adsorption capacity is very strong,
Because the electron microscope of calcium carbonate attritive powder is in spongy porous, porosity in taking pictures, surface is just very big, therefore begins
Very strong suction-operated, exchange interaction are kept eventually.3, the design that gas-solid mixer is made of outer cylinder and chimney fan is of the invention
The three of technical characteristic.The purpose of this design is: chimney fan covers in outer cylinder, and the annular housing between outer cylinder and chimney fan
Upper and lower side is sealing cover, while multiple air inlets are opened on outer tube wall, and multiple air ports are provided on the wall of chimney fan, to make gas-solid
Mixer, which forms a surrounding (periphery), has multiple air nozzles that intersect, multiple to intersect what air nozzle was sprayed
Air-flow enables porous calcium carbonate pellet sufficiently to mix with the micronic dust in the ultra-fine flue gas of metal smelt, and then micronic dust is adsorbed on carbon
Under sour calcium pellet, calcium carbonate pellet is made not stop to grow up by adsorbing micronic dust in the circulating cycle, and it is micro- in the ultra-fine flue gas of metal smelt
Dirt is cleared, to achieve the purpose that purify the ultra-fine flue gas of metal smelt.4, super as metal smelt using Sinter-plate Filter
Calcium carbonate absorption carrier, which is run, in thin flue gas micronic dust treatment process leaks the removal of micro micronic dust and remedies and arrange the design of rotation, is of the invention
The four of technical characteristic.The purpose of this design is: sintering panel filter made due to using special sintering plate material
Filtering element, thus compared with traditional deduster for making filter element with fiber filtering, have the advantages that many uniquenesses, it can
The dust and gas room that dust-contained airflow is entered to middle part cabinet by the deflector of dust and gas inlet, is passed through by sintered plate purified gas
Blower discharge, with the increase for being delayed at dust on sintering plate surface coating, timing or the deashing control for determining differential pressure working method
System processed would automatically turn on fast-open type pulse valve, the dust of sintering plate surface effectively be removed by compressed air, by landing
Dust is discharged after falling under gravity into ash bucket, and concentration of emission can reach much smaller than 1mg/Nm, effectively filters dust grain
Diameter >=0.1um.Secondly as the coating of PTFE has extremely strong hydrophobicity and non-stick, it can be just containing a large amount of steam
Often work, adapts to strong acid and strong base operating condition, it is contemplated that service life >=10 year, and it is capable of washing, it is renewable, it can be recycled.
