The lattice model, which is a generalization of the pseudospin Blume-Emery-Griffiths model, is proposed for the description of the dipole particle intercalation in the layered crystalline medium. The processes of the dynamical reorientation (of the tunnelling-type) of the dipole momenta of intercalated particles are taken into account at the formulation of the model. The phase diagrams of the system are built in the mean field approximation. The transitions between the dipole-ordered and disordered phases as well as the phases with the different particle concentrations are described. The changes in the phase diagram topology depending on the relations between the interaction constants and tunnelling parameters are analyzed.
