Abstract
The invention relates to a method for removing sulfide in oil burning boiler tail gas. The method includes the step that the oil burning boiler tail gas is introduced into enough desulfurizer through a pipeline, and sulfur dioxide, sulfur trioxide and hydrogen sulfide in the tail gas react with the desulfurizer to form complex precipitates to be filtered out. The desulfurizer is prepared from, by weight, 5,7-trihydroxy-2-(3,4,5-trihydroxy phenyl)-4H-1-benzofuran-4-ketone, harringtonin, 7-hydroxy-6-methoxy-2H-1-benzofuran-2-ketone, pentahydroxy flavone-3-rhamnoside, 3-methyl pyridazine, 4-acetoxyl-3-methoxy-(2-propenyl) benzene, 4,4'-sulfonyldiphenylamine and the like. According to the treatment method, the capacity of complexing the target substances is high, the speed of forming the complex precipitates is high, the removal rate can reach 99%, cost is low, usage amount is small, scale formation is avoided, and the environment is not damaged.
Description
Technical field
The present invention relates to a kind of processing method removing oil burning boiler sulfur dioxide in tail gas, sulfur trioxide and hydrogen sulfide, belong to environmental protection technical field.
Background technology
Desulfurizing agent refers generally to remove the medicament of free sulphur in fuel, raw material or unclassified stores or sulphur compound; Mainly refer to remove (the such as SO of sulfur-containing compound in waste gas in the control and process of pollutant
2, SO
3and H
2s) medicament used.Conventional several desulfurizing agent has: calcium-based desulfurizing agent, sodium base desulfurizer, Mg-base desulfurizing agent, amino desulfurizing agent etc.
Calcium-based desulfurizing agent is applied the most general in desulfurization, and conventional calcium gene sulphur agent has lime, calcium hydroxide, carbide slag, lime stone and dolomite etc., also can take from industrial residue and the raw material of rich calcium.The advantage of this technique is that investment is low, and desulfurization degree can reach 70%-80%, and shortcoming easily produces lime scale formation.
Sodium compound is used for wet scrubbing technique (Na
2cO
3) and furnace injection and duct injection (NaHCO
3) make desulfurizing agent in technique.Wet scrubbing technique mainly uses, especially in less power plant and Industrial Boiler in the U.S..The advantage of this technique is that investment is low, and desulfurization degree can reach 70%, and has the denitrification percent of 10% ~ 20%.Shortcoming is that the sodium salt produced is soluble in water, and slag directly discharges and easily produces pollution.
Ammonia is generally used in electron beam irradiation sulfur removal technology and ammonia stripping technique using the form of ammoniacal liquor or ammoniacal liquor as desulfurizing agent.The activity of amino desulfurizing agent is fine, and therefore consumption other desulfurizing agents relative will lack.Be ammonium sulfate with the sulfur removal technology byproduct of amino desulfurizing agent, can be used as agricultural fertilizer and use.But the price of amino desulfurizing agent is higher, need special transport, storage, metering and conveying equipment, the leakage of ammonia can cause stench, the environmental problem such as poisoning.
Mg-base desulfurizing agent comprises MgO, Mg (OH)
2deng.Magnesia (light calcined magnesia), magnesium hydroxide have stronger shock-absorbing capacity (pH value is the highest is no more than 9), and higher activity and adsorption capacity, can reach the desulfuration efficiency of more than 95%, accessory substance magnesium sulfate recoverable.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of method removing oil burning boiler tail gas medium sulphide content, oil burning boiler tail gas is passed in enough desulfurizing agents by pipeline, sulfur dioxide in tail gas, sulfur trioxide and hydrogen sulfide and desulfurizing agent react, form complex compound sediment and be filtered removal, described desulfurizing agent comprises the component of the following meter of mark by weight:
