Description
Przedmiotem wynalazku jest srodek zwilzajacy, przeznaczony do zmniejszania zapylenia w przemysle weglowym, cementowym oraz w elektrowniach.The subject of the invention is a humectant intended to reduce dust in industry coal, cement and power plants.
Przy urabianiu wegla wystepuje silne jego zapylenie, zjawisko to jest bardzo szkodliwe dla czlowieka.When coal is mined, there is a strong dusting of it, this phenomenon is very harmful to people.
W celu zmniejszenia zapylenia przy kombajnach instaluje sie urzadzenia zraszajace. Woda kopalniana bardzo slabo zwilza pyly weglowe, dodanie wiec srodka zwilzajacego do wody zraszajacej powoduje znaczne skrócenie czasu zwilzania pylków i lepsze efekty odpylenia.Sprinklers are installed next to combines to reduce dust. Mine water very much it does not moisten coal dust so adding a wetting agent to the spray water causes a significant reduction in time of wetting pollen and better dusting effects.
Opisany w patencie nr 80448 srodek do wiazania pylu weglowego sklada sie z zawierajacej wode mieszaniny zelowatego wodorotlenku magnezowego, bedacego substancja nosnika, soli hygroskopijnych, zwilza- czy i siarczanu wapniowego w ilosci 3—50% wagowych.The coal dust binding agent described in Patent No. 80448 consists of a water-based mixture of gel-like magnesium hydroxide, which is a carrier substance, hygroscopic salts, and calcium sulfate in an amount of 3 to 50% by weight.
Znany jest równiez srodek zwilzajacy z patentu nr 77261, który zawiera 20-60% wagowych, najkorzystniej 40% wagowych soli sodowej sulfobursztynianu dwu-2-etyloheksylowego oraz 40-80% wagowych, najkorzystniej 60% wagowych, soli rozpuszczalnych w wodzie o charakterze kwasnym, obojetnym lub zasadowym, najkorzyst¬ niej chlorek wapnia.Also known is a wetting agent from Patent No. 77261, which contains 20-60% by weight, most preferably 40% by weight of sodium di-2-ethylhexyl sulfosuccinate and 40-80% by weight, most preferably 60% by weight of water-soluble salts of an acidic, neutral or basic nature, most preferably it is calcium chloride.
W przemysle weglowym stosowano srodki zwilzajace, zawierajace kerylobenzenosulfonian sodu w postaci stalej i w postaci roztworów. Srodki te okazaly sie jednak malo skuteczne w szczególnosci w twardych wodach, posiadaja równiez slabsza rozpuszczalnosc od nowoczesnych srodków zwilzajacych.In the coal industry wetting agents containing sodium kerylbenzene sulphonate in the form of solid and in the form of solutions. However, these measures have proved to be little effective, in particular in hard waters, they also have lower solubility than modern wetting agents.
Istota wynalazku jest srodek zwilzajacy stosowany zwlaszcza do likwidacji zapylenia skladajacy sie z 4-10 czesci wagowych polietoksylowanych alkoholi, zawierajacych od 6-22 atomów wegla w lancuchu alkilowym i od 2-40 moli tlenku etylenu w lancuchu polietylenoglikolowym, 1-10 czesci wagowych polietoksylowanego alkilofenolu zawierajacego od 4—40 moli tlenku etylenu w lancuchu polietylenoglikolowym i/lub od 0,5-10 czesci wagowych rozpuszczalnika organicznego, korzystnie metanolu, etanolu, etylocelosolu, butylocelosolu oraz wody w ilosci uzaleznionej od wymaganej konsystencji srodka.The essence of the invention is a wetting agent used especially for the elimination of dust, consisting of 4-10 parts by weight of polyethoxylated alcohols containing 6-22 carbon atoms in the alkyl chain and from 2-40 moles of ethylene oxide in a polyethylene glycol chain, 1-10 parts by weight of polyethoxylated an alkylphenol containing from 4 to 40 moles of ethylene oxide in the polyethylene glycol chain and / or from 0.5-10 parts by weight of an organic solvent, preferably methanol, ethanol, ethyl cellosol, butyl cellosol and water in an amount depending on the required consistency of the agent.
Spelnienie szerokiego wachlarza wlasnosci wymaga odpowiedniego dobrania skladników srodka zwilzajace¬ go i ich synergetycznego dzialania. Otrzymano srodek o dobrych wlasnosciach zwilzajacych i odpowiednich wlasnosciach fizykochemicznych. Dobór srodków typu niejonowego uwarunkowalo dobre wlasnosci zwilzajace2 100 461 w bardzo twardych wodach oraz odpornosc na alkalia i kwasy. Przez dodanie rozpuszczalnika otrzymano srodek bardziej stabilny o odpowiednio niskiej lepkosci, koniecznej dla wlasciwej pracy urzadzenia rozpylajacego, oraz ulatwia to wszelkie operacje przy transporcie.Fulfilling a wide range of properties requires the appropriate selection of the ingredients of the wetting agent it and their synergetic action. A product with good wetting and suitable properties was obtained physicochemical properties. The selection of non-ionic type agents resulted in good wetting properties2 100 461 in very hard waters and alkali and acid resistant. An agent was obtained by adding the solvent more stable with sufficiently low viscosity necessary for proper operation of the spraying device, and this simplifies all transport operations.
Srodek zwilzajacy wedlug wynalazku stanowi jednorodny roztwór, który rozpuszcza sie w wodzie calkowicie i mozliwie szybko w duzym zakresie stezen w temperaturze 10-30°C. Posiada bardzo dobre wlasnosci zwilzajace w wodzie kopalnianej, której twardosc wynosic moze do 300°N. Jest to srodek nietoksycz¬ ny i nieszkodliwy na skóre i blony sluzowej. Do oceny wlasnosci zwilzajacych srodka zastosowano metode polegajaca na okreslaniu czasii toniecia 0,2 g pylu weglowego trudno zwilzajacego sie w 200 cm3 roztworu srodka zwilzajacego o temperaturze 25°C Zaleznosc wlasnosci zwilzajacych od stezenia srodka zwilzajacego w roztworze przedstawiono w tabeli I. Ze wzrostem stezenia substancji aktywnej do stezenia 0,15% nastepuje wyrazny spadek czasu toniecia pylu czyli wzrost wlasnosci zwilzajacych roztworu.The wetting agent according to the invention is a homogeneous solution that is dissolved in water completely and as quickly as possible in a large concentration range at 10-30 ° C. It has very good wetting properties in mine water, the hardness of which can be up to 300 ° N. It is a non-toxic agent ny and harmless to the skin and mucosa. The method was used to assess the wetting properties of the agent based on the determination of the sinking time of 0.2 g of hard-wet coal dust in 200 cm3 of solution wetting agent at 25 ° C. Dependence of wetting properties on wetting agent concentration in the solution are presented in Table I. The concentration of the active substance increases to 0.15% a significant decrease in the dust sinking time, i.e. an increase in the wetting properties of the solution.
