Description
Technical field
The present invention relates to the application process of chemical industry nano composite material, be specifically related to the heavy antisepsis composite material of nanofiber and the application in the wet desulphurization concrete chimney.
Background technology
For further implementing State Council's " comprehensive programme of work of energy-saving and emission-reduction " and " energy-saving and emission-reduction statistical monitoring and examination embodiment and way ", improve operational efficiency and the managerial skills of coal desulfurization facility, guarantee to realize that the Eleventh Five-Year Plan total sulfur dioxide reduces discharging target, conscientiously strengthen the supervision to coal desulfurization facility operation process, conscientiously strengthen operation, the maintenance and management of desulfurization facility, guarantee normal operation and the desulfuration efficiency of desulfurization facility, for adopting the high-efficiency flue gas desulfurization system to seem particularly important.
The inner normal operating temperature of desulfurization after funnel is between 50～100 ℃, and temperature reduces, and smoke moisture increases greatly; Acid dew-point temperature due to flue gas reduces simultaneously, and inner wall of stack is dewfall very easily, the SO of remnants in flue gas
3The rear formation of dissolving corrosivity, the dilute sulfuric acid solution that permeability is very strong, cause very strong corrosivity to chimney structure.Chimney finds that in use there is many places Seepage in various degree in the outer side tube-wall of chimney, and sepage forms crystallization on the stack shell surface, forms the bulk icicle winter.Former chimney coated inside has lost antiseptic effect.
The anticorrosion means of desulfuration chimney commonly used and the problem that faces
From present situation, the technological means that can effectively prevent desulfurization after funnel inner wall corrosion is very limited, and common method comprises: titanium alloy liner, stainless steel inner lining, steel cylinder liner add anticorrosive paint, adopt the bonding glass block of acidproof friendship mud and glass flake etc.; In these methods, except the high titanium alloy liner of cost has preferably anti-corrosion function, objectively to say, the anticorrosion time that other comparatively economic anticorrosion means can play is very limited, almost can't be over 1 year.The reason that causes present anticorrosion means can't obtain promising result mainly comprises following three aspects:
(1) have flexible gap between the anticorrosion wall of acidproof brick that adopts segmentation to support, present anticorrosion means can't solve the etching problem that gap location exists, and cause SO
3The dilute sulfuric acid solution that forms after dissolving passes gap, inner wall of stack is formed corrosion, and penetrate very soon chimney wall, causes serious potential safety hazard.
(2) different from the coefficient of expansion of acidproof friendship mud as adhesive due to acidproof brick, after the temperature through after a while alternately changes, gap, SO will inevitably appear between both
3Dilute sulfuric acid solution will be by these trickle crevice corrosion inner wall of stack.
(3) in order to address the above problem, traditional anti-corrosion method has to enter gap at acidproof brick surface sticking glass scale to prevent acidic liquid; But the coefficient of expansion as the glass flake of rigid material itself is different from acidproof brick, between the two adhesive force limited (being approximately only 0.4～1.0 MPa) in addition, alternately variation and the passing of time along with temperature, cause glass flake layer seepage and come off in a large number, thereby losing anti-corrosion function.
Due to corrosion, a large amount of hard-earned useful materials become waste material, and due to the immoderate exploitation of people and use raw material, tellurian limited resources are just day by day exhausted.Introduce according to " Chinese Investigation On Corrosion report ", the whole world just had one ton of steel corrosion to become iron rust in every 90 seconds, corrosion is annual engulf a country then GDP 3%～5%, by this calculating, China's corrosion loss was about 20000 trillion yuan in 2011.
Anticorrosion is an old problem, is also world's hard nut to crack.Prevent that the method for corrosion of metal and the research of material is not only a great problem in science, and have important effect and status in national economy.The development level of heavy anticorrosive material how, and performance how, becomes the sign of a national science technical merit of sign.For further implementing State Council's " comprehensive programme of work of energy-saving and emission-reduction " and " energy-saving and emission-reduction statistical monitoring and examination embodiment and way ", improve operational efficiency and the managerial skills of coal desulfurization facility, guarantee to realize that the Eleventh Five-Year Plan total sulfur dioxide reduces discharging target, conscientiously strengthen the supervision to coal desulfurization facility operation process, conscientiously strengthen operation, the maintenance and management of desulfurization facility, guarantee the normal operation of safety and the desulfuration efficiency of desulfurization facility, for adopting the high-efficiency flue gas desulfurization system to seem particularly important.

Heavy anticorrosion basic principle introduction:
The variation that metal material surface state occurs due to the chemistry that is subject to surrounding medium (atmosphere, high temperature, fused salt, non-water or water-bearing media) or electrochemical action also is converted into cenotype, thereby make metal material be subjected to destroy, this phenomenon is referred to as metal erosion.Metal erosion is a spontaneous process, and very serious.
Metal erosion can be divided into following several types:
1. electrochemical corrosion.Metal forms battery and the corrosion that causes in the aqueous solution, be topmost research object in the anticorrosion field.
2. chemical attack.The for example high-temperature oxydation of iron and steel fire door, and anhydrous solution forms battery.
3. biological corrosion.The for example bacterial corrosion of underground buried tube.
By its corrosion product type, metal erosion can be divided into again following two kinds:
1. film-forming type.During as aluminum oxidation, generate aluminum oxide film, the further oxidation that metal has been delayed in resistance.Metal when high-temperature slightly and the reaction of airborne oxygen generate oxidation film, when rete was very thin, oxygen can easily see through, oxidation makes speed that film thickens have nothing to do with film thickness and is constant.
2. film-forming type not.For example steel plate is in salt solution, the Fe that anode produces
2+Film forming on the spot, must meet the OH that negative electrode produces leaving the anode place.Ion precipitation becomes Fe (OH)
2, then at skin, be oxidized to iron rust FeOOH, or Fe
20
3.nH
20, can not generate the further corrosion of film barrier metal closely on the steel face.
Electrochemical corrosion can be summarized as following 3 points
1, can only cause metal material to destroy and can not make to external world the short circuit galvanic cell of useful work.
2, the power of corrosion cell effect is from the chemical affinity of corrosion reaction.
3, in corrosion cell, must have a kind of equilibrium potential of cathodic reduction reaction of material at least higher than the equilibrium potential of the anodic solution of the metal of corrosion failure reaction.
In the aqueous solution,, due to the potential difference of different metal, can produce battery.Even at same metallic plate, difference in oxygen concentration between etc., all can produce potential difference and cause corrosion because difference, the difference of composition of weld line, the concentration of electrolyte solutions of its local internal stress are poor, in temperature difference, solution.
Take steel plate as example, the corrosion cell reaction is:

3(corrosion product)
Oxygen reduction reaction in acid, neutral, alkaline medium is most important reaction for anticorrosive coating, in the corrosion of general atmosphere and marine environment, all belongs to this type of.Due at the alkalogenic OH in negative electrode position.Ion, can make grease type, the saponification of alkyd type paint film peel off.In addition, because should reaction must participate in by aerobic, and very low at seawater depths oxygen concentration, therefore the metal erosion reaction is very slow.Daily some corrosion of seeing is because the oxygen concentration difference causes, as under rivet, rusty scale is inferior all because of the oxygen supply, becomes less anode.Dew on steel plate drips, and outer oxygen supply is many and form negative electrode, and Central oxygen-supply is few and become anode, and corrosion pit as shown in Figure 1.
The corrosion that is caused by the oxygen concentration difference shown in Figure 1
The driving force of corrosion cell is two interelectrode potential difference △ E.So the corrosion current of this battery is
I=
R in formula
a---anode resistance;
R
cOne cathode resistor
R
e---electrolyte solution resistance;
R
w---external circuit resistance.
Corrosion current is larger, and corrosion rate is faster.
The protection of metal erosion
, in order to reduce corrosion, must reduce corrosion current, at original E
c-E
eIn constant situation, can adopt resistance to control S rj (good thick-layer paint film), anodic control (anodic passivity), cathodic control (retardance cathode reaction).The mixing that also can take to have anodic control, resistance control and cathodic control concurrently is controlled, and controls corrosion.
People have taked many measures to reduce the loss of corrosion, but so far still with organic coating for the most effective, most economical, application is the most general.Coating is a kind of chemical materials; be coated on object plane and can protect it not to be subjected to the erosion of environment; also can give simultaneously (as car paint) attractive in appearance, livery (as the Chinese red of bay mechanical hazard parts), camouflage (as weapons such as battlebuses) etc.; and coating decoration is convenient; needn't need large-scale baker as enamel; electroplate to need the equipment such as electroplating bath, also needn't only limit the use of under water as cathodic protection, underground submergence position.Coating object can be as big as bridge spanning the sea, drilling platforms, and is little to bicycle, tin can etc., so range of application is wide; And the maintenance coating is convenient, is far from enamel, electroplates and can compare.The coating of very thin only part millimeters thick, play etch-proof effect really effectively.
Usually, the coating of rich zinc and crome metal, copper is traditional anti-corrosion of metal material, but these anti-corrosion of metal materials have certain limitation at aspects such as environmental protection, resource and costs.Therefore, explore the novel anticorrosion material green, that cost is low and have considerable economic and social benefit.
Nano material refers to the material of the characteristic size of material component in the 1-100nm scope.When the size of a particulate is little during to nanometer scale, its microstructure and properties both had been different from the microsystem of atom, molecule, also was different from the bulky grain material meta system that shows eigen character, but a transition system between both.The nanoparticle size is little, and specific area is large, has very high surface energy, thereby its chemical property is had a significant impact.After experiment showed, that the particle decentralization is brought up to a certain degree,, along with reducing of particle diameter, be positioned at the atomicity of particle surface and the ratio of total atom number and sharply increase, when particle diameter was reduced to 5nm, the surface atom proportion can reach 50%.Because the surface atom number increases, in particulate, atomicity reduces, enable with in electron energy level divide, the level spacing (1 * 12 after division
-2-1 * 10
-5EV).Nano material has small-size effect, surface-interface effect, quantum size effect and macro quanta tunnel effect due to himself structural feature, thereby with the conventional material of same component, compare, have many unusual performances at aspects such as catalysis, optics, magnetic, mechanics, demonstrate good development prospect aspect heavily anticorrosion.
