Description
Technical field
The present invention relates to a kind of foam suppressing airborne dust and injection apparatus thereof, belong to dedusting technology field.
Background technology
The technique processed as iron ore powder sintering dressing, sintering region is the district that ironmaking region airborne dust is the most serious
One of territory.In sintering region, sintering deposit from central cooler out, is had bad luck by finished belt, is transported to blast furnace
Use (or leaving raw material stock ground in).In sintering deposit conveying engineering, due to having bad luck between belt, chute
At position, airborne dust easily occurs, welding.Although sintering finished region covering and at belt on belt feeder
Installing dust arrester on chute, but airborne dust situation still happens occasionally, anti-dust effect has much room for improvement.
In order to reach more preferable dust removing effects, fundamentally reduce the generating capacity of dust, typically can be to sintering deposit
Transportation is sprayed chemical dust suppressant.For chemistry dust suppression, chemical dust suppressant can be generally divided into moistening
Type, binding type and coagulation type three class, dust suppression mechanism be mainly moistening, consolidate, solidifying cake three kinds effect.State
The achievement in research of outer relevant chemical dust suppressant a lot, as the U.S. Coherex dust suppressant, Japanese poly-third
Olefin(e) acid salt dust suppressant, Germany magnesium chloride and quick lime dust suppressant and the polyacrylate of Australia, complete
Methylcellulose dust suppressant etc. is used widely.China current dust suppressant research still have one compared with abroad
Determining gap, be mainly reflected in surfactant monomer few, of poor quality, dust suppression efficiency is low, and (relatively clear water is the highest
60%-90%), dust suppressant high in cost of production aspect.And, the technical field of existing dust suppressant injection apparatus
In, the main pooled applications of equipment in mine, coal works, road surface dust suppression etc., press down in sintering deposit transportation
The research of dirt almost without.
Summary of the invention
It is an object of the invention to provide a kind of foam suppressing airborne dust and injection apparatus thereof, existing to solve
There are the problems referred to above in the presence of technology.

Its effect of foam dust suppression agent is to produce substantial amounts of foam in the mixture of water and air, and this is a kind of
Another typical material that do, stable chemical nature, similar, when foam solution is sprayed to the foam that shaving cream produces
Time on Ore or stockpile, cause void-free foam coverage and blocking dirt source, make dust be moistened and press down
System.The mechanism of action of foam dust suppression is similar to water spray dust with mode, mainly has height due to foaming agent
The surfactant of frothing capacity, further comprises dust wetting agent and binding agent, but compared with the latter, its
Improve liquid phase distribution, thus reduce usage amount, improve the capture effect to inhalable particles.
It is generally believed that the depositing dust of inhalable particles is realized by phagocytosis and moistening inhalable particles,
Additionally also likely to be present " shrapnel " effect, i.e. when lather collapse, its fragment meeting and inhalable particles
Thing contacts, by it moistening and cohesion.Specifically, the efficient surfactant in chemical blowing agent, it
Molecular structure in there are hydrophilic and two compatibility gene groups of oleophylic, it is easy to by hydrone exclusion and from
Inside is to external migration and is enriched in surface, forms hydrophilic group hydrophobic group inwardly low free energy surfaces outwardly,
Thus reduce the surface tension of water.There is data to show, as long as adding the foam of 0.1%, water can be made
Surface tension is from 71dyn/cm2Drop to 30～40dyn/cm2.For dusting solid thing, due to water
Reduction in surface tension, absorption result reduces the interfacial free energy between dust and water, thus improves fall
The effect of dirt.What is more, foaming agent nozzle exit pressure one timing bubbling process in, Interfacial Adsorption shape
The surface tension become can reduce foam particle diameter, increases bubble amt, improves collision trapping probability, helps
In improving depositing dust ability.On the other hand, the thin dirt being dried is difficult to collide because of the repulsion of surface charge
Cohesion, and containing binding agent in foaming agent, can effectively change the free energy current potential of particle surface, carry
The surface activity of high dust, makes micronic dust and dust collision rift be condensed into larger-diameter grit, thus accelerates
Sedimentation.
Industry water passes through booster water pump and stop valve, is transported in concentration regulation electromagnetic pump；Dust suppression medicament leads to
Cross stop valve, be transported in concentration regulation electromagnetic pump.Industry water and dust suppressant regulate electromagnetic pump in concentration
In, form the water pharmaceutical mixture of normal concentration.Compressed air is carried by stop valve.Compression sky
Gas, water and pharmaceutical mixture carry out pressure balance by corresponding pressure-regulating valve and pressure-regulating valve respectively
Regulation, it is ensured that both pressure is equal.So, the compressed air that pressure is equal and water and pharmaceutical mixture
Fully bubble in bubble chamber, form cystose dust suppressant.Stop valve is passed through in foam dust suppression agent, arrives spray
Mouth.Foam dust suppression agent is sprayed on the sintering deposit on finished belt work surface by nozzle uniformly uniformly,
Reach the anti-dust effect in sintering deposit course of conveying.
The beneficial effects are mainly as follows: in sintering deposit course of conveying, spraying dust suppressant can be effective
Reduce sintering deposit dust raising phenomenon generation, improve sintering finished conveyor zones and sintering deposit Belt Conveying periphery
Environment, to realize sintering region clean produce have great importance.
