Description
Technical field
The present invention relates to a kind of liquid waste incineration flue gas purifying equipment, more particularly to it is a kind of available for the net of high temperature saliferous flue gas
Change equipment, the equipment can also be used for the purified treatment of the high-temperature flue gas such as kiln, catalyst recovery.
Background technology
Liquid waste incineration is a kind of effective method of current processing industrial wastes, is had in numerous industrial process extensive
Using.The gas cleaning process that liquid waste incineration is produced mainly have of both problem, one is that heat in high-temperature flue gas needs back
Receive and utilize；Two be the recovery of salt needs or removal in flue gas, makes flue gas qualified discharge.It is especially high during liquid waste incineration
In the combustion process of bisulfate waste liquor, heat exchange equipment inwall is easily sticked in the salt particle of molten condition, pipe on the one hand can be caused
The blocking and corrosion in road, on the other hand can cause the heated inequality of boiler, there is the danger of explosion.Although can be gone by wet sprinkling
Except the particulate matter in flue gas, but the waste water formation secondary pollution produced needs to discharge after after-treatment, to being returned with height
The salt of value is received, difficulty is extracted also higher.Other wet sprinkling can not be in recovered flue gas heat, cause the waste of the energy.
Recovered flue gas heat can both have been made full use of by being thus badly in need of one kind, again can salt effectively in recovered flue gas, reach flue gas
Mark the efficient waste liquid flue gases purification of discharge.
Bag-type dusting especially membrane bag filter dedusting has very high efficiency of dust collection, to the removal that average grain diameter is 2.5 μm
Rate can reach more than 99.99%.But it is passed through the flue-gas temperature after air cooling and still reaches 600 ~ 700 degree, ordinary filter can not be met
Heatproof requirement.If will be dropped to flue-gas temperature below 260 degree of the scope of application of filter bag by heat exchanger, the salt of precipitation can not can be kept away
The absorption exempted from causes a hidden trouble in heat exchanger inwall, is unfavorable for the utilization of heat.
CN105169815A discloses a kind of dust removal method of the high-temperature flue gas of high salt bearing liquid wastes incinerator, first passes through pipeline
Air cooled flue gas is passed through, then realizes by inertial dust separator the separation of solid particle salt and flue gas, it is to avoid salt particle is in heat exchange
Boiler surfaces are bonded.But cooled down by simple pipeline blowing air, its mixing efficiency is unfavorable for the precipitation of salt particle than relatively low.
And inertial dust separator efficiency of dust collection is relatively low, having considerable amount of particle can not still be removed.
CN101520182A discloses a kind of full automatic liquid waste incinerator, and flue gas is utilized using the heat exchanger of secondary combustion chamber
Waste heat, and water-cooled deduster removal part fine particle therein is first passed through, removing remaining particle by sack cleaner.
Its process route is complicated, and the flue gas with particulate matter has had salt absorption in inwall when by heat exchanger cooling.In addition, water cooling
The waste water that deduster is produced can cause secondary pollution problem, in addition it is also necessary to carry out purified treatment to waste water.It is wet by the flue gas of washing
Degree is larger, is unfavorable for follow-up sack cleaner operation, easily causes blocking.
Because ceramic membrane is that inorganic particle sinters form at high temperature, it is possible to more than 1000 DEG C of heatproof, thus it makes
It can be greatly improved with the life-span.Further, since ceramic membrane has unsymmetric structure, it can solve to breathe freely using surface filtration technology
The problem of amount can not get both with dust rejection, makes equipment have the advantages that gas treatment amount is big and dust rejection is high.Ceramics
Film is more and more applied in the purification of high-temperature gas, but for the liquid waste incineration flue gas especially flue gas containing fuse salt
Processing has not been reported.
CN206103562 U disclose a kind of high-temperature smoke purifier, can not be handled available for common organic filter bag
High-temperature flue gas field.But the flue gas device is without flue gas refrigerating function, it is impossible to be applied to during liquid waste incineration.In addition,
The device is simple filtration system, the occasion larger to dust concentration, and easily causing to build bridge blocks, and causes filtration resistance anxious
Play rises.
The content of the invention
Present device is provided with cyclone dust collectors below the integrated filtering area of ceramic membrane, on the one hand available for high-temperature flue gas
It is that the salt particle of molten condition separates out old solid granulates with being sufficiently mixed for air；On the other hand, it can remove what is separated out in flue gas
Part salt particle, reduces the dust granules concentration into ceramic membrane filter area, is conducive to reducing operation pressure and service life,
Reach double effectses.
The present invention provides a kind of liquid waste incineration flue gas purifying equipment, and the purpose is to made not causing ventilation inwall to adsorb salt
In the case of clog, the heat in flue gas is made full use of, salt that can also be effectively in recovered flue gas, and do not result in any
Secondary pollution.The use of high temperature resistant and corrosion resistant ceramic membrane is filter material, to high-temperature flue gas and with good applicability, ceramics
Film has the double dominant of high Air permenbility and high filtering precision.
Another free-revving engine of the present invention is fully to combine heat exchange cooling, dust removal process, on the one hand enhances and exchanged heat
Journey, by providing the mixed zone of air-flow, makes the salt in flue gas effectively separate out.Another aspect cyclone structure makes the salt of generation first be gone
Remove.Compact equipment, forms the efficient coupling of plurality of devices, significantly improves the operational efficiency of equipment.
