PP-II-23REAKTOR-FIBRIDATORLagusseva E.I., Pankratov E.A., Nikiforov V.A.The Tver State Technical UniversityQuay А.Nikitin, house 22, Tver, Russialagusseva@yandex.ruReactionary casting of fibrids by the method of gas-fluid polycondensation is oneof the most perspective and ecologically clean. Fibrids have anizometrichnoe texturewith incorrect form, high specific surface and ability for binding together in the masswith the leaflike materials formation. That’s why they are adjusted to the syntheticpapers production and electrotechnical and constructional function, filter materialsand elements, not weaved materials [1, 2].SuspensionThe construction of reactor-fibridator wasdeveloped. It is vertical cylindrical reactor (pic. 1),which includes reaction chamber 5 and a gas-formingchamber located under it. The gas-forming chamber1HMDAconsists of sprayer blender 9 and evaporatoroverheater310. The reaction chamber is realized indifferent variants of basic design: with grate at the gas2phase input (pic. 1) and non-grate one of confusordiffuserAirtype (pic. 2), sprayer and split way of liquidCAphase feed. It provides liquid-gas interface, diffusion ofacidylable and acidylating monomers from volumetowards phase interphase (reaction space), thechemical process of monomer polycondensation1 – reaction chamber;2 – sprayer blender;3 – evaporator-overheater;CA – dicarboxylic acid dichlorides;HMDA – hexamethylenediaminePic. 1. The reactor-fibridator==n H 2 N-R-NH 2 + n Cl-C-R'-C-ClOOO=O=-HN-R-NH-C-R'-C-n + 2n HCland neutralization of low-molecular product of polycondensationHCl + NaOH NaCl + H 2 O ,it also provides the fibrids molding from gel-like polymer firm during its creation inturbulazed three-phase foam conditions by means of shift voltage.The engineering calculation of the generation gas-phase box and of thereactionary box of the reaktor-fibridator technique is developed.374
