Definitions

  • ABSTRACT The method of removal of smoke particularly in confined areas by spraying an aqueous solution of a surfactant into the smoke.
  • an object of this invention is to provide a novel and improved method of erasing smoke easily without use of any special device.
  • an aqueous solution of a surfactant is sprayed into the smoke to settle the smoke particles.
  • the surfactants usable for this purpose are, for example, dialkyl sulfosuccinates, alkyl sulfates, alkyl benzenesulfonates, ricinolic ester sulfates, alkyl esters, of oz-sulfofatty acid, monosodium a-phosphonofatty acid esters, dialkyl phosphates and polyoxyethylenealkyl sulfates (degree of polymerization: 2-20) as anion surfactants, and polyoxyethylenealkyl phenols (degree of polymerization: 2-20), polyoxyethylenealkyl ethers (degree of polymerization: 2-20) and tripolyoxyethylenealkyl phosphates (degree of polymerization: 2-20) as nonion surfactants.
  • the smoke erasing rate in this example is given by Curve 1 of the drawing with respect to the spray time.
  • EXAMPLE 2 The test was carried out under the same conditions as that of Example I, except that l% aqueous solution of the surfactant was used in place of the 0.5% solution.
  • the smoke erasing rate was measured as shown by Curve 2 of the drawing and it was 68% after 30 seconds and 77% after 60 seconds and indicated clearly an increase in the smoke erasing effect over Example I.
  • EXAMPLE 3 This test was carried out for the purpose of comparison under the same conditions as that of Example 1, except that the same amount of water was used in place of the surfactant solution.
  • the smoke erasing rate was measured as shown by Curve 3 of the drawing. More specifically, it was 20% after seconds and 36% after 60 seconds and clearly indicated the effect of surfactant in comparison with the above examples.
  • EXAMPLE l7 One killogram of nylon and killograms of Japanese sedar wood were smoked and the smoke was fed into the chamber of Example 1. 1% aqueous solution of sodium di-Z-ethylhexyl sulfosuccinate was sprayed in the chamber and the concentrations of hydrogen cyanate and ammonia were measured by gas chromatography. It was found that the concentration of hydrogen cyanate was reduced from 1,000 p.p.m. to p.p.m. and the concentration was reduced from 4,600 p.p.m. to 30 p.p.m. within three minutes respectively.
  • the improvement comprising the steps of forming a aqueous solution containing up to about l% of a surfactant wherein said surfactant constitutes at least one substance selected from the group consisting of dialkyl sulfosuccinates, alkyl suflates, alkyl benzenesulfonates, recinolic ester sulfates, alkyl esters of a-sulfofatty acid, monosodium a-phosphonofatty acid es ters, dialkyl phosphates. polyoxyethylenealkyl sulfates, poiyethylenealkyl phenols, polyoxyethylenealkyl ethers and tripolyoxyethylenealkyl phosphates and then spraying said solution into the smoke filled area to settle the smoke particles.
  • a surfactant constitutes at least one substance selected from the group consisting of dialkyl sulfosuccinates, alkyl suflates, alkyl benzenesulfonates,
