Description
Technical field
The present invention relates to a kind of under hot conditions the antichlor and preparation method thereof of deep removal chlorine-containing gas, belong to the high-temperature flue gas purification processing technology field.
Background technology
Studies show that the waste incineration that the generation of chlorine-containing gas is mainly derived from the fossil fuel burning of coal and sharply increases.If the chlorine-containing gas in its flue gas is discharged into the increase that can cause acid rain in the atmosphere, and can all cause huge harm to nature and the mankind, in combustion system equipment is also had very large harm in addition: the chlorine-containing gas in the flue gas is highly acid, 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, the service life of the serious shortening equipment of meeting.Special HCl gas easily with desulphurization system in desulfurizing agent react and generate the chloride of volatile, make the desulfurized effect variation, and the obstruction pipe-line system.And chlorine-containing gas can promote the problems such as PCDD/PCDF generation under middle high temperature; If remove chlorine-containing gas in lower temperature, can bring comparatively serious energy loss to power plant, be equivalent to reduce the net electric generation problem of 13%-37%.Therefore, removing HCl in middle high temperature is one of core missions of vent gas treatment.
Removing of HCl had higher requirement in integrated coal gasification combined cycle (IGCC) system and in the coal gasification fuel cell (MCFC).In the IGCC system, the existence of HCl can be verified corrosion combustion gas turbine blade, requires the content of HCl in the combustion gas can not surpass 0.5ppm; In the MCFC system, the HCl in the combustion gas is easy to form low-boiling compound with wherein electrolyte, and this compound at high temperature is easy to evaporation and causes electrolytical loss, according to one's analysis, if as long as the content of HCl reaches 1ppm in the combustion gas, cell resistance is increased, cause cell voltage to reduce.Therefore, the high temperature dechlorination also is one of core missions of IGCC and MCFC system.
The antichlor that removes at present chlorine-containing gas in the flue gas all concentrates in the medium and low temperature scope, and the chlorosity of antichlor is all very low, and accommodation is narrow.Therefore research and develop that the degree of depth efficiently seems particularly important at the antichlor of chlorine-containing gas under the high temperature.
