Abstract
The invention relates to a method for removing sulfur dioxide, sulfur trioxide and hydrogen sulfide in tail gas of an oil burning boiler. The method comprises the steps of introducing a sufficient amount of desulfurizing agent into the tail gas of the oil burning boiler through a pipeline, carrying out reaction on sulfur dioxide, sulfur trioxide, hydrogen sulfide and the desulfurizing agent to obtain complex precipitates, and filtering for removing the complex precipitates. The desulfurizing agent comprises the following components by weight percent: 2-ethoxybenzaldehyde, 4-methoxybenzyl bromide, cyclohexanone, triethylamine, 3-buten-1-ol, 1-tetralone, tritolyl phosphate, 3-dimethylaminopropylamine, 2-methoxy-5-fluorouracil, isopropylamine, 1-boc-3-piperidone, ethyl oxalyl monochloride and ethyl alcohol absolute. According to the method, the complexing capability with target substances is strong, the complex precipitate formation speed is high, the removal rate can up to 99%, the cost is low, the using amount is small, and scaling cannot occur, so that the environment cannot be damaged.
Description
Technical field
The present invention relates to a kind of 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.
