FOAM GENERATING (MODIFICATIONS) Russian patent published in 2003 - IPC

FIELD: civil engineering, in particular, devices for foam generation. SUBSTANCE: the foam generator has ducts for supply of foaming agent and gaseous component, mixing chamber, dispersing chamber filled with dispersing material, foam generating nets. The dispersing chamber is made in the form of a bent tube. The foam generator includes the ducts for supply of foaming agent and gaseous component, foam generating nets, mixing chamber, dispersing chamber filled with dispersing material and has inner partitions. The inner partitions of the dispersing chamber are installed for multiple variation of the direction of foam flow inside the dispersing chamber. The foam generator has ducts for supply of foaming agent and gaseous component, foam generating nets, mixing chamber, axially symmetric, round in cross-section dispersing chamber filled with dispersing material and having inner partitions. The inner axially symmetric partitions are made to the shape of the walls of the dispersing chamber with a diameter decreasing in the direction to the axis and are positioned coaxially. The partitions are attached to the chamber walls or to one another through the inner ribs and installed for provision of multiple variation of the direction of foam flow inside the dispersing chamber. The foam generator includes the ducts for supply of foaming agent and gaseous component, foam generating nets, mixing chamber, dispersing chamber filled with dispersing material. It is provided with several dispersing chambers, each made in the form of a prism or cylinder, or part of a cylinder with the end walls in the foundations of the mentioned figures and holes in the lateral faces near the foundations, the chambers are positioned to provide for foam displacement through the holes in the lateral faces from the mixing chamber to the foam generator outlet branch pipe through all the dispersing chambers. EFFECT: enhanced homogeneity of foam, simplified manufacture and use of the foam generator. 42 cl, 16 dwg
