Description
Technical field
The present invention relates to antichlor of a kind of deep removal HCl gas under middle hot conditions and preparation method thereof, belong to gas cleaning processing technology field.
Background technology
The output of current China domestic waste has reached 1.6 hundred million tons every year, and still with annual 8 ~ 10% speed increase, that wherein can carry out harmless treatment accounts for 66%, nearly 1/3 rubbish can only carry out simple landfill, China clears disposal of refuse and spends nearly 30,000,000,000 yuan every year, city, 600, the whole nation has been stacked or all kinds of rubbish of landfill reaches 8,000,000,000 tons, and rubbish is stored up and added up to occupy 500,000,000 square metres of soils, and 2/3 city faces " garbage-surrounded city ".The process problem of house refuse is very urgent, burning disposal because having significant minimizing (decrement about 80%, subtracts appearance 90%), resource (recoverable energy be used for generating and heat supply) is widely used by U.S., day, method, moral, Yi Deng developed country.China starts late, and the First garbage incinerating power plant set up for 1988, garbage incinerating power plant has reached over thousands of seat so far.On April 29th, 2012, the General Office of the State Council has printed and distributed " planning of " 12 " national application of city life garbage harmless treatment Facilities Construction ", waste incineration project construction is proposed and quantizes to require: by 2015, whole nation application of city life garbage burning disposal facility ability, reach more than 35% of harmless treatment total capacity, its Middle Eastern reaches more than 48%.
Because component of refuse is quite complicated, in burning process, inevitably secondary pollution problem to be produced.And the problem of the HCl burnt away the refuse in the sour gas of generation more and more causes the extensive concern of international community.Different from fire coal, the abundant chlorinated organics (rubber, PVC etc.) contained in house refuse and inorganic matter (NaCl) can mainly be discharged with the form of HCl, up to hundreds of even several thousand PPm in burning process.The basic principle of, minimizing innoxious according to urban garbage disposal and resource, effectively must control these pollutants.
Chlorine is one of important element causing secondary pollution in consumer waste incineration, and its existence directly has influence on design, the operation and maintenance of incinerator; And chlorine can change into HCl and give off, atmospheric environment and CIU are worked the mischief.HCl in air may react at normal temperatures with water vapour: OH+HCl-Cl+H
2o, the Cl of generation can as catalyst breakage ozone layers in high stratosphere gas-bearing formation, and meeting and SO
2deng formation acid rain, animals and plants and building are worked the mischief.At refuse burning system, the burning facility body of HCl to incinerator causes strong corrosion, can cause the high temperature corrosion damage of furnace heating surface and the cold end corrosion of back-end surfaces, can cause the raising of steam parameter, cause the corrosion on heated exchanger surface, also can promote NO
xgeneration, the desulfurizing agent of the HCl gas in coal gas easily and in desulphurization system reacts and generates the chloride of volatile, desulfurized effect is deteriorated, and blocks pipe-line system.Chlorine also can affect migration and the distribution of heavy metal, and forms dioxin, particularly at 300 ~ 400 DEG C as one of element.Point out in the report " incinerator and human health " that United Nations Environment Programme announced 20 end of the centurys, waste incineration is the largest source of dioxin.Estimate that the dioxin given off by incinerator accounts for 10% ~ 40% of total release in the world.Therefore, removing HCl gas at middle high temperature is one of core missions of garbage incinerator tail gas process.
Current antichlor can be divided into by chemical constituent: modified aluminas system antichlor, copper system antichlor, calcium system antichlor and ferripotassium system antichlor.But the exploitation due to each antichlor is targetedly, different antichlors is suitable for different occasions.And most of antichlor be mainly applicable in, under cryogenic conditions, the chlorosity of antichlor is not high, under middle high temperature, the harm of HCl gas can not be avoided.Therefore in research and development, under high temperature, the degree of depth efficiently seems particularly important at the antichlor of HCl gas.
Summary of the invention
Goal of the invention: not high for the antichlor chlorosity existed at present, and adaptive temperature scope is wideless, the problem of HCl gas in efficient deep removal flue gas under high temperature in cannot realizing, the invention provides antichlor of a kind of deep removal HCl gas under middle hot conditions and preparation method thereof, this antichlor has high HCl content in wide temperature range.
