Detailed description of the invention
The utility model is by increasing stabilizer and reductor device to peroxide passivation desulfurizer, overcome start-stop car in existing peroxide passivation sulfur removal technology technology and easily cause instability, in diluted acid, remaining hydrogen peroxide easily causes dysgenic problem to follow-up equipment and downstream product.
Adopt the flue gas peroxide passivation devulcanizer 4 of band stabilizer 3 in the technical solution of the utility model, the effect of stabilizer can reach the object that hydrogen peroxide contacts with stabilizing agent when needed.In one case, stabilizer is a pipeline, and pipeline tapping is at circulating slot, and the pipeline other end is connected with stabilizing agent source.When needing, stabilizing agent adds in circulating slot by this pipeline tapping by stabilizing agent source, and namely the stabilizing agent added contacts with hydrogen peroxide and reach stable object.In another case, hold the stabilizing agent for preventing decomposing hydrogen dioxide solution in stabilizer, when needing, stabilizer is opened, and stabilizing agent is discharged in circulating slot.Both of these case is all stabilizing agent release, reaches stabilizing agent and contacts with hydrogen peroxide.The stabilizing agent worked in this way can be liquid or solid-state, such as stabiliser solution or graininess stabilizing agent.
Stabilizing agent can adopt the various reagent that can prevent decomposing hydrogen dioxide solution.In general, hydrogen peroxide is more stable under faintly acid and neutrallty condition, and activates in the basic conditions, can fast decoupled under heavy metal ion exists.Relate to adopt in the field of hydrogen peroxide application hydrogen peroxide can be stoped uncontrolledly to decompose added reagent be called hydrogen peroxide stabilizer.The type of hydrogen peroxide stabilizer has multiple, such as absorbent-type, chelating type or mixed type etc., and heavy metal ion can be isolated by modes such as absorption and chelatings by they, avoids affecting hydrogen peroxide product.Conventional hydrogen peroxide stabilizer also has the types such as siliceous or not siliceous.Siliceous stabilizer package is containing the such as silicate such as sodium metasilicate, magnesium silicate stabilizing agent, and they have excellent adsorption capacity, have good physical and chemical adsorption characteristic to metal ion, thus reduces the catalytic action of metal ion.Not siliceous stabilizer package is containing types such as such as soaps.Also have macromolecule stabilizer, they form large scale structure by forming macromolecule network structure, have very strong suction-operated, and can be obtained by finishing and well adsorb isolation effect.Some conventional small molecule chelators are also conventional hydrogen peroxide stabilizers, they are coordinated with macromolecule, can obtain good stabilized hydrogen peroxide effect.Chelating type stabilizing agent is generally multivalence organic acid or its salt, such as carboxylate, phosphonate etc.Hydrogen peroxide stabilizer can be buied from suppliers, such as, purchased from the ST-1/2 stabilizing agent of Jiangsu Cheng Tian Environmental Protection Technology Co., Ltd, also oneself can prepare, such as, adopts EDTA to carry out Stabilizing Hydrogen Peroxide as chelating agent.
In another embodiment, stabilizing agent adopts the stabilizing agent that is fixed on carrier or stabilizing agent itself to be the solid-state stabilizing agents of macromolecule, such as waterglass and polyacrylamide amine stabiliser.In this case, stabilizing agent is contained in stabilizer, and stabilizer is when needed in opening kenel or be open kenel always, and when making to need, hydrogen peroxide can contact with stabilizing agent, reaches the Undec object of Stabilizing Hydrogen Peroxide.
Peroxide passivation flue gas desulfurization device comprises the circulating slot of superposed desulfuration absorber and bottom, hydrogen peroxide in dioxygen tank 1 pumps into devulcanizer by dioxygen water pump 2 through pipeline, after smoke contacts, tail gas is discharged by devulcanizer top, and reacted liquid drops in the circulating slot of bottom.Stabilizer 3 is arranged on bottom circulating slot, is buried in absorbing liquid, after allocating hydrogen peroxide solution into, plays the object that Stabilizing Hydrogen Peroxide does not decompose in initial driving circulating slot.During driving, by the stabilizing agent in stabilizer and the hydrogen peroxide obtain solution entering devulcanizer first simultaneously or inserted before hydrogen peroxide in circulating slot, play the effect of Stabilizing Hydrogen Peroxide obtain solution.And stabilizing agent is by always along with circulating in devulcanizer of liquid is circulated, and do not need other interpolation, or can add again after operation a period of time yet, with stabilizer concentration certain in ensureing to circulate.
Desulfuration absorber can be form conventional in this area, and the apparatus-form such as such as void tower, packed tower, hypergravity machine, can adopt one or more levels desulfurization to absorb according to actual conditions.
Preferably no matter adopt which kind of form desulphurization plant, all can arrange the removal device to thing foam in flue gas, what removal device was preferential selects nonmetallic silk screen, filler or its combining form.
Circulating fluid enters separator by cyclic absorption pump 5.Separator is separator conventional in peroxide passivation desulfurization process, for separating of the sulfuric acid that desulfurization produces.Liquid after separation proceeds devulcanizer, under by top spray, fully contacts with sulfur-containing smoke gas.
The dilute sulfuric acid separated, before discharge, preferably enters reductor and processes.The reducing agent for decomposing remaining hydrogen peroxide in by-product dilute sulfuric acid is accommodated in reductor.For holding the container that the reductor of reducing agent is non-metallic material making, inside is filled with the reducing agent material that can decompose remaining hydrogen peroxide in dilute sulfuric acid, is equipped with liquid inlet, liquid outlet and gas discharge outlet; Dilute sulfuric acid containing remaining hydrogen peroxide enters from liquid inlet, and be sprayed at above the inner reducing agent loaded, remaining hydrogen peroxide is broken down into water and oxygen is emptying from gas discharge outlet, and liquid is discharged from liquid outlet.Decomposing hydrogen dioxide solution is and foregoing stabilization opposite effect, as long as the reagent that therefore can accelerate decomposing hydrogen dioxide solution can be used as reducing agent used herein, preferably through fixing catalyst, such as metal oxide bed, such as with the Solid Bed that the material comprising manganese dioxide-catalyst is made, described reducing agent is such as purchased from the ST-1 reducing agent of Jiangsu Cheng Tian Environmental Protection Technology Co., Ltd.
Adopt the flow process of desulfurizer desulfurization of the present utility model as follows:
Step 1, hydrogen peroxide desulfurization.Sulfur-containing smoke gas enters the main device of peroxide passivation flue gas desulfurization of band stabilizer, absorbs sulfur dioxide wherein through cyclic absorption pump circulated sprinkling in desulfuration absorber containing hydrogen peroxide solution, and after absorbing, gas is containing sulfur dioxide 20mg/Nm
3, emptying after removing thing foam except thing foam device.When initial driving or start-stop car, stabilizer plays and stable newly add hydrogen peroxide and do not decompose, and reduces the object of its consumption.The continuous cyclic absorption of sulfur dioxide in flue gas, after liquid dilute sulfuric acid concentration to be recycled reaches the requirement numerical value within 10-40%, open circuit outer row part dilute sulfuric acid.The balance of the liquid, concentration etc. of desulphurization system is maintained by continuous supplementation hydrogen peroxide, continuous supplementation fresh water (FW).Preferably, keep hydrogen peroxide concentration within 0-10.0%, more preferably, remain within 0-1.0%.
Step 2, remaining hydrogen peroxide in reduction decomposition dilute sulfuric acid.Dilute sulfuric acid containing remaining hydrogen peroxide enters reductor liquid inlet, and be sprayed at above the inner reducing agent loaded, remaining hydrogen peroxide is broken down into water and oxygen is emptying from gas discharge outlet, and liquid is expelled to dilute sulfuric acid from liquid outlet and concentrates thickening device.
