Description
Technical field
The invention belongs to Ferrous Metallurgy chemical technology field, relate to a kind of inhibition desalination agent, particularly to one
Plant dry type TRT inhibition desalination agent and preparation method thereof.
Background technology
Blast furnace gas excess pressure power generating turbine plant, is called for short TRT, is mainly used in institute in blast furnace ironmaking process
The pressure that the side-product (blast furnace gas) produced is had can be with the recovery of heat energy, recyclable blast furnace air
The 30%-50% of energy, remarkable in economical benefits needed for machine, be a kind of well energy-conserving and environment-protective dress of iron and steel enterprise
Put.
The medium of TRT device is the coal gas after blast furnace roof removing dust out, although use dry
Formula dedusting, but gas phase media also can remain a number of dust and saturated steam.In addition,
Coal gas also has can not be fully erased in equipment mist of oil, and produce many because blast furnace raw material is impure
Plant sour gas (such as hydrogen sulfide, hydrogen chloride, carbon dioxide etc.).Therefore eventually enter into TRT device is
Gu the multiphase flow of gas-vapour-composition.After coal gas enters TRT unit, the sour gas in coal gas is dissolved in
Condense in water and form one layer of acid moisture film at blade surface, blade surface is caused corrosion failure, after corrosion
Metal surface smoothness drastically decline so that corrosion product, greasy dirt, dust etc. are attached on blade,
Simultaneously as the decline of gas temperature, flow velocity, pressure etc., some salt forming component in coal gas also can be
The positions such as the moving vane of device, stator blade and import and export flue form a large amount of stratiform Structure Phenomenon, dust stratification
Thickness is up to 100-150.Owing to dirty is uneven at each position of equipment, device dynamic equilibrium is destroyed,
Causing TRT generated output to reduce, spindle vibration value constantly increases until automatically mediating, the turnaround of unit cycle
Short, most notably within 3-5 days, need maintenance down.
Summary of the invention
It is an object of the invention to provide a kind of dry type TRT inhibition desalination agent and preparation method thereof, this inhibition
Desalination agent can effectively prevent the Korrosionsmedium in flue gas to flue and the corruption of TRT turbines vane
Erosion, prevents the fouling on blade of impurity and salt forming species.
In order to achieve the above object, dry type TRT inhibition desalination agent of the present invention presses mass fraction, by 40～50%
The dispersion of double iodate octadecyldimethyl ether ammonium salts, 30～the organic mixture of 40%, 15～20% auxiliary
Furtherance membrane and 5～10% methanol compounding form；Wherein, organic mixture be glycerol phosphate,
Methylbenzene a pair of horses going side by side three nitrogen and PESA mix with the mass ratio of 2:2:1.
Described dispersion secondary film formers is organic phosphate.
Described dispersion secondary film formers is sodium ethylenediamine tetramethylenephosphonate, ethylenediamine tetramethylene phosphonic acid
Or diethylenetriamine penta.
The preparation method of a kind of described dry type TRT inhibition desalination agent, by double iodate octadecyldimethyl
Ether ammonium salt, organic mixture, dispersion secondary film formers and methanol add in container, are sufficiently mixed and stir
Mix uniformly, obtain the inhibition desalination agent of dry type TRT.
Compared with prior art, the beneficial effects of the present invention is:
Dry type TRT inhibition desalination agent of the present invention is by double iodate octadecyldimethyl ether ammonium salts, organic
Mixture, dispersion secondary film formers and methanol are compounding to be formed, and therefore operation is simple for its preparation method.
And this dry type TRT inhibition desalination agent can form corrosion-mitigation scale-inhibition protecting film on TRT turbines vane, keep
Blade and other metal surface, position are smooth, stop impurity attachment, and to TRT turbines vane metal without appointing
What corrosion, destroys crystallization behavior and the orientation of inorganic salts on TRT turbines vane, prevents it from depositing.
It addition, the dry type TRT inhibition desalination agent of the present invention has specific aim to TRT turbines vane polymorphic type fouling,
On-the-spot application performance is stable.In use, the dry type TRT inhibition desalination agent of the present invention only need to use dosing pump
It is filled into gas-pipe line continuously, instant vaporization can form corrosion-mitigation scale-inhibition film, reach anticorrosion-antiscaling effect,
The most easy to use.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, described in be explanation of the invention
Rather than limit.
Dry type TRT inhibition desalination agent of the present invention, it is characterised in that: by mass fraction, by 40～50%
The dispersion auxiliary of double iodate octadecyldimethyl ether ammonium salts, 30～the organic mixture of 40%, 15～20%
Film former and 5～10% methanol compounding form；Wherein, organic mixture is glycerol phosphate, first
Base benzene a pair of horses going side by side three nitrogen and PESA mix with the mass ratio of 2:2:1.Dispersion secondary film formers is for having
Machine phosphate, preferably sodium ethylenediamine tetramethylenephosphonate, ethylenediamine tetramethylene phosphonic acid or divinyl three
Amine pentamethylene phosphonic acids.
Wherein, double iodate octadecyldimethyl ether ammonium salt molecular structures are:
The preparation method of this dry type TRT inhibition desalination agent is by double iodate octadecyldimethyl ether ammoniums
Salt, organic mixture, dispersion secondary film formers and methanol add in container, are sufficiently mixed and stir,
Obtain the inhibition desalination agent of dry type TRT.
Using the dry type TRT inhibition desalination agent of the present invention, its chemical feeding quantity can be according to TRT device fouling condition
Depending on, general chemical feeding quantity is 80-100ppm, joins in the blast furnace gas pipeline before TRT device portal,
Residual temperature by blast furnace gas gasifies, and the medicament after gasification uniformly mixes in flow of gas with flue gas
Enter turbine, it is achieved medicament is direct effective suppression to causing TRT device foulant under gaseous state
And dispersion.The dry type TRT inhibition desalination agent of the present invention have simultaneously film forming, clean metallic surfaces and in
With the function of acidic materials, turbine blade service life can be obviously prolonged.
The corrosion-mitigation scale-inhibition mechanism of the dry type TRT inhibition desalination agent of the present invention is specific as follows:
1, after the agent of dry type TRT inhibition desalination sprays into blast furnace gas, realize by gas temperature and kinetic energy moment
Gasification and uniformly mixing.
2, the agent of dry type TRT inhibition desalination is crystallizing with the inorganic salt crystal generation eutectic in coal gas or absorption
On surface, twist cell, destroys crystallization behavior and the orientation of inorganic salt；Change the crystalline state of crystal,
Avoid intergranular bonding and form tridimensional network, stop continuously forming and growing of crystal, it is therefore prevented that coal
Salt crystal (dirty) in gas is at site deposition such as turbine Bigpian, rotors.
3, the active component in the agent of dry type TRT inhibition desalination, can cleaning blade surface, elimination metal surface
Electric charge, stops impurity to adhere on blade.
4, the agent of dry type TRT inhibition desalination blade surface formed corrosion-mitigation scale-inhibition protecting film, stop salt component and
The material contact blade surfaces such as sour gas, keep blade and other metal surface, position of device smooth.
5, the agent of dry type TRT inhibition desalination can absorb the sour gas in coal gas, reduces acidic gas concentration,
Reach corrosion mitigating effect, prevent spot corrosion.
6, the dry type TRT inhibition desalination agent of the present invention is applicable to integrated iron and steel works' blast furnace gas excess pressure power generating
Turbine, is filled into gas-pipe line continuously with dosing pump, to TRT device because of the coal gas group after dry dust removal
The fouling caused is divided to have good scale effect.
