Contain vapor, SO in wet flue gas2、NO2, molecule (micronic dust), volatile materials and other compounds etc. it is miscellaneous
Matter, according to the division of different enterprises, smoke components are different.
PM10 blocking apparatus in method of the invention mainly uses membrane separation technique, to (being greater than PM10) larger in flue gas
Particle (micronic dust) sieved, filtered, filtered particle is recycled by automatic remover, and PM10 particle row is imported
Outlet.It is in High Temperature Gas through in the filtered flue gas of this device, the larger particles in flue gas are removed, and smoke behavior remains unchanged
Body state.
Wet flue gas purification separation cabinet flue gas in method of the invention enters in the perforated membrane under low temperature, cools down through condensation,
Flue gas is in " liquefied ", and wherein vapor is condensed into rapidly liquid condition, along with the condensation of vapor, contains originally in flue gas
Pernicious gas, such as SO2、NO2Equal pernicious gases are dissolved in perforated membrane, are in ionic condition: such as inferior sulfate radical, sulfate radical, nitric acid
Root, chloride ion etc., and the impurity such as particle less than PM10 also enter in perforated membrane；Flue gas is after liquid filter membrane filters sublimate
Become cryogenic gas, discharged by air flue, main purpose is release device pressure, no longer contains harmful gas in the gas of discharge
Body and objectionable impurities.
The effect of COD device in method of the invention mainly to contain in perforated membrane harmful substance, impurity, particle
Etc. being handled, solid and liquid separation, solid recycling, the purpose that liquid circulation utilizes are realized.
It is weakly acidic after membrane filtering flue gas, and with inferior sulfate radical, sulfate radical, nitrate anion, chloride ion, small solid
The impurity such as body particle, first pass around pH-meter, balance by acid-base integration, into flocculation stirring device.The work of flocculation stirring device
It is uniformly distributed with all kinds of ions and particle that are to maintain in liquid, it, being capable of rapid generation so that into after combined reaction kettle
Learn reaction, inferior sulfate radical, sulfate radical, nitrate anion, chloride ion etc. in purifying liquid.
In combined reaction kettle, the gas of generation is absorbed by ammonia nitrogen filter membrane, the bisalt ion in liquid filtering
Precipitating, becomes solid particle, is discharged with other granule foreigns, into PM2.5 separator.
PM2.5 separator in method of the invention: it after all kinds of solid particle polluters enter equipment from channel, is adjusting the speed
Under the action of motor, liquid stirs by evenly mixing, passes through graphene superconduction filter membrane by certain pressure.Through filter membrane mistake
Liquid after filter is recycled by liquid outlet into condensation cycle aquaporin, and solid impurity is discharged by particle discharge ports,
Into solid recovery unit.The filter membrane main function of the device is to remove the solid particle for being greater than PM2.5 in liquid, according to reality
Border uses, and also adjustable filtering membrane aperture dispels smaller solid impurity.The design of second swivelling tool-holder, not only makes liquid
In solid impurity can be uniformly distributed, quickly filter, improve filter efficiency, while can prevent filter membrane surface from blocking, energy
Effective operation of enough long-acting guarantee equipment.
The present invention is not limited to above-mentioned optional embodiment, anyone can show that other are each under the inspiration of the present invention
The product of kind form.Above-mentioned specific embodiment should not be understood the limitation of pairs of protection scope of the present invention, protection of the invention
Range should be subject to be defined in claims, and specification can be used for interpreting the claims.
