Description
Technical field
The invention belongs to Minepit environment protection and mine safety production technical field, be specifically related to a kind of for atomizing de-dusting, blow out construction process depositing dust and other froth breaking type dust-inhibitor relating to wet spray depositing dust and preparation method thereof.
Background technology
Dust is pit mining, storage, handling, transport and store up the fine particle produced in process, can be suspended in air for a long time, cause ambient atmosphere visibility meter to reduce, cause operator to suffer from pneumoconiosis disease, and may cause mine safety production accident.According to statistics, in dust-settling technology used at present, wet spray depositing dust is one of technology generally used.But due to the hydrophobic property of dust granules, atomized water spray depositing dust can only by effects such as collision, interceptions, and the dust granules making granularity slightly large lands, and dust-laying effect is subject to certain impact undoubtedly.Exploitation and use dust-inhibitor, by improve dust wetting property, reduce spray water surface tension, impel dust especially microfine dust be wetting and reunite, can dust-laying effect be improved.For this reason, dust-inhibitor exploitation and be used in mine dust suppress in more and more paid much attention to.Dust-inhibitor, in raising atomizing de-dusting effect, especially improves the dust-laying effect aspect of respirable dust, has played more and more important effect.
But because dust-inhibitor forms primarily of tensio-active agent, many moist type tensio-active agents often have certain latherability, cause, in prepared dust-inhibitor, usually there are some foams; In addition, because dust-inhibitor is the liquid that various ingredients mixing forms.As everyone knows, mono-component liquid can not produce foam, and the polycomponent mixing liquid containing two or more often can produce foam; And dust-inhibitor is in preparation and production process, in dissolving, mixing, whipping process, inevitably brings some air into, make to form foam in dust-inhibitor; In addition, when atomizing de-dusting, because strong atomizing, also can make to produce bubble in dust-inhibitor.The existence of foam, not only can affect uniformity and the disperse properties of mixing solutions, but also may affect the character of spraying droplet further.
By observing many wet spray depositing dust processes, finding that the lathering property of dust-inhibitor is good, foam can be caused too much, because produce more foam after spraying, and affecting the wetting behavior of droplet to dust granules, even affect atomizing de-dusting effect.Time serious, bring certain influence even can to the normal operation of fog system.And the foam in spray process is too much, can affect the atmospheric visibility of operationlocation to a great extent, bring extreme influence, even cause mine safety production accident to the normal production of operator.So, suitably controlling latherability and the foam degree of dust-inhibitor, even keeping the safety in production all most important for keeping the performance of dust-inhibitor.

Simultaneous test 2
Joined by dispersion liquid containing multiple defoamer in the obtained dust-inhibitor of embodiment 1 ~ 6, measure the foam height of froth breaking type dust-inhibitor, measuring method, with simultaneous test 1, the results are shown in Table 3.
The foam height (cm) of what table 3 recorded the add froth breaking type dust-inhibitor that multiple defoamer obtains
As can be seen here, the composite obtained dispersion liquid containing defoamer of multiple defoamer, the lathering property adding froth breaking type dust-inhibitor obtained in dust-inhibitor has obvious decline, show as the foam height that after adding defoamer, dust-inhibitor produces obviously to decline, and time standing, the speed of bubble collapse increases, and causes the foam height after 30min significantly to reduce
Simultaneous test 3
Dispersion liquid containing defoamer adds froth breaking type dust-inhibitor obtained in dust-inhibitor, should not affect the wettability of dust-inhibitor to dust.Therefore, five kinds of froth breaking type dust-inhibitors are selected to carry out studying the wettability of seven kinds of different coal dusts respectively.Adopt on kapillary and determine the moisture uptake of coal dust to different dust-inhibitor solution to osmose process, the results are shown in Table 4.
Table 4 measures the froth breaking type dust-inhibitor that obtains to the moisture uptake (g) of coal dust
Can find out, the wettability of froth breaking type dust-inhibitor provided by the invention to coal dust remains essentially in a certain degree.That is, after defoamer adds in dust-inhibitor and makes froth breaking type dust-inhibitor, certain scope is basically stable to the moisture uptake of coal dust.This shows, does not affect the wettability of dust-inhibitor to coal dust after adding defoamer, and froth breaking type dust-inhibitor can carry out the wetting of coal dust completely and suppress.
As can be seen here, froth breaking type dust-inhibitor provided by the invention can be eliminated foam in dust-inhibitor or keep the foam appropriateness in dust-inhibitor, to ensure the uniformity of dust-inhibitor, stability and the wettability to dust.During use, froth breaking type dust-inhibitor can carry out quick humidification and reunion to dust equally, impels dust especially respirable dust agglomerate landing, reaches the object of efficient depositing dust, improve atomizing de-dusting efficiency, especially improve the dustfall efficiency of respirable dust.When particularly using froth breaking type dust-inhibitor in narrow and small closed space, down-hole, be unlikely because a large amount of foaming, affect the atmospheric visibility of operationlocation, ensure the operational safety of operator.This shows, froth breaking type dust-inhibitor can be widely used in most occasion and carry out atomizing de-dusting.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
