Abstract
Disclosed is a gaseous phase scale inhibitor for multiple types of gas booster fans. The gaseous phase scale inhibitor comprises the following components of, by mass, 30%-45% of polyaspartic acid, 5%-10% of diethylenetriamine, 5%-10% of ethylene distearamide, 30%-45% of hexamethylenediamine tetramethylene phosphonic acid and 1% -10% of petroleum ether. The scale inhibitor is added into a blast furnace gas pipeline in front of an inlet of a compressing blower through a metering pump and atomized fast by means of residual temperature of blast furnace gas and kinetic energy of the gas. The atomized scale inhibitor enters a fan cavity channel and makes complete contact with the surface of a fan rotor along with the gas, and the purposes of protection and scale inhibition for the fan rotor and blades in the gaseous (atomized) state are achieved. The gaseous phase scale inhibitor for the multiple types of gas booster fans is suitable for scale inhibition for blast furnace gas, coke oven gas, converter gas and other multiple types of gas booster fans.
Description
Technical field
The invention belongs to Ferrous Metallurgy chemical technology field, be specifically related to a kind of gas phase scale inhibition for polymorphic type coal gas booster fan
Agent.
Background technology
Coal gas booster fan is that iron and steel enterprise's Gas Pressurization Station is for improving gas pressure and flow velocity, it is achieved a kind of weight of user's request
Want instrument.Chemical analysis in coal gas is complex, and ash is more, and coal gas of converter reclaims from fall cover, and the scrubbed tower in road, electricity remove
Though dustiness basically reaches requirement after dirt processes, pipeline carries, gas holder precipitates.But, due to the seriality produced, coal gas increases
Pressure fan must run for 24 hours continuously, and the coal gas amount of accumulative conveying is many, and dust quantity is the most at the adhesion amount of impeller, once
Dust fouling just makes pressure reduce, and flow reduces, and unit produces vibration, needs maintenance down, and deashing processes.Cause the biggest labor
Fatigue resistance and economic loss.There are the problems referred to above in integrated iron and steel works' coal gas booster fan, brings to the normal safety in production of production
The biggest impact, it is desirable to solve this problem by ancillary method.
Summary of the invention
Present invention aims to the defect of above-mentioned existence, it is provided that a kind of gas phase scale inhibition for polymorphic type coal gas booster fan
Agent, this antisludging agent can effectively prevent the impurity in flue gas and salt forming species from depositing fouling on flue and booster fan.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of gas phase antisludging agent for polymorphic type coal gas booster fan, by mass percentage, composed of the following components: poly-sky
Winter propylhomoserin 30～45%, diethylenetriamines 5～10%, ethylene group bis-stearamides 5～10%, hexamethylene diamine tetramethylene
Phosphoric acid 30～45% and petroleum ether 1～10%.
By mass percentage, composed of the following components: poly-aspartate 30～40%, diethylenetriamines 5～8%, ethylene group
Bis-stearamides 5～10%, hexamethylene diamine tetramethylene phosphoric acid 30～40% and petroleum ether 4～10%.
By mass percentage, composed of the following components: poly-aspartate 38～40%, diethylenetriamines 5～6%, ethylene group
Bis-stearamides 5～10%, hexamethylene diamine tetramethylene phosphoric acid 35～40% and petroleum ether 6～10%.
By mass percentage, composed of the following components: poly-aspartate 39%, diethylenetriamines 8%, ethylene group are double hard
Acyl amine 5%, hexamethylene diamine tetramethylene phosphatase 24 0% and petroleum ether 8%.
Compared with prior art, the invention have the benefit that
1. utilize microgranule footpath dust in chemical method dispersion coal gas, increase aerosol stability:
Organic macromolecule polymer (Polysucciuimide) present in polymorphic type coal gas booster fan antisludging agent due to the present invention is logical
Crossing coal gas and be carried along into blower fan tract, may be uniformly dispersed in coal gas by fan rotor rotation function, such material chemistry is special
Property determine that it on various molecule surfaces at gas phase rapid adsorption and can produce electrostatic repulsion and make each microgranule disperse, it is to avoid sedimentation,
Return thick.This antisludging agent can greatly strengthen the stability of " aerosol " so that after dust particle passes through the entrance of blower fan workshop section
Continuous gas piping.
2. can change fan rotor metal surface state reach suppress dust particle deposition effect:
Ethylene group bis-stearamides in the polymorphic type coal gas booster fan antisludging agent of the present invention has permeates by force, and wetting action can
So that fan rotor metal surface forms uniform lipophilic-hydrophobic property " molecular film ", " molecular film " Solid micro should can be substantially reduced
Surface and interface tension force between thing and metal, reduces the metal surface absorption affinity to dust particle." molecular film " adds continuously at medicament
Time be in the dynamic steady state of " formed-peel off-formed " all the time at blade surface.Generation-the stripping process of film can also make possibility
The dust particle of deposition sheds into subsequent pipeline with film, stops rotor dust.
3., when using, this antisludging agent adds in the blast furnace gas pipeline before compression fan entrance by dosing pump, by blast furnace gas
Residual temperature and coal gas self kinetic energy rapid atomization, medicament after atomization enters blower fan tract, with coal gas and fan rotor surface
Completely attach to, it is achieved to fan rotor and blade protection and the purpose of scale inhibition under gas (mist) state.Polymorphic type coal gas booster fan
Antisludging agent is applicable to the scale inhibition of the polytype booster fans such as blast furnace gas, coke-stove gas, coal gas of converter.
