Description
Technical field:
This utility model relates to SO in a kind of flue gas dry cleaning device, especially removing flue gas2、NOX, dust, hydrargyrum, two
The reverse-flow integration activated coke smoke eliminator of the pollutant such as English.
Background technology:
China's industrial gas emission standard is increasingly stricter, to controlling SO in waste gas2、NOXThe pressure of discharge capacity is bigger.Mesh
Front flue gases purification technology in a wet process is main, consumes great lot of water resources, easily causes secondary pollution, and can not desulfurization simultaneously take off
Nitre, produces theory run counter to China energy-saving and emission-reduction, green industry.
Flue Gas Purification Technology Using Activated Coke is a kind of renewable, dry FGD process technology of resourcebility, utilizes activated coke
Characterization of adsorption, the dust in pollutant, SO in efficient removal flue gas2、NOX, hydrargyrum, the pollutant such as two English, moreover it is possible to removing wet method
Technology is difficult to the SO removed3, it is to avoid the series connection construction of different pollutant purification devices in flue gas, simultaneously can also to ultra-fine
Dust (PM10) has certain purification.Be applicable to purify coal-fired flue-gas, gas from oil burning, flue gas of refuse burning, heavy oil divide
Solve flue gas and sintering flue gas etc..
Adsorption-type desulfurizing tower and adsorption-type denitrating tower are the nucleus equipments of activated coke dry FGD process device.Industry at present
The fixed bed desulphurization denitration technology that mostly is of middle application and moving bed desulphurization denitration technology, the wherein treatment quantity of fixed bed unit
Relatively low, it is impossible to adapting to industrial production demand, and moving bed is big due to the optimum contact area of gas-solid, purification efficiency is high, treating capacity
The advantage such as big, has higher industrial application value.Wherein moving bed desulphurization denitration technology presses the side of contact of flue gas and activated coke
Formula is divided into and flows, adverse current and three kinds of modes of cross-flow.Parallel type operation mass transfer force is relatively low；Activated coke during cross-current type operation
Can not be fully utilized, exist and be not fully contacted the phenomenon being just discharged with flue gas, thus activated coke consumption is big, circulating load is also
Greatly.And the activated coke in counterflow moving bed, its activity is along tower top to being gradually lowered at the bottom of tower, and the final activated coke discharged is almost
Being complete deactivation, activated coke is fully utilized with the whole process of smoke contacts, and therefore activated coke consumption is little, and circulating load is also
Little, thus reduce regeneration energy consumption and operating cost.
But existing counter-current operation technology exists after activated coke is introduced into denitration region and enters back into desulfurization zone.Denitration reaction generates
NH4HSO4(NH4)2SO4It is liquid between 147～350 DEG C, is generally solid in adsorptive reactor, and has temperature fluctuation
Time may liquefy, therefore one layer of sticky mass may be adhered in activated coke surface.And now activated coke enters back into desulfurization zone
Time, activated coke can be lumpd because of the existence of attachment or block absorption duct, thus activity is greatly lowered.
A kind of flue gas desulfurization and denitrification tower based on activated carbon disclosed in CN203043829U, it is simply that typical counter-current operation,
Activated coke enters back into desulfurization zone after being introduced into denitration region.Denitration product is easily occurred to make activated coke inactivation affect de-during practical operation
Sulfur effect.
