METHOD OF PREPARING EMULSION OF WATER IN OIL TYPE FOR EMULSION EXPLOSIVE COMPOSITION AND DEVICE FOR ITS PREPARATION Russian patent published in 2010 - IPC C06B21/00 C06B47/14 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of emulsion explosive substances. Method of preparing water in oil type emulsion for emulsion explosive composition includes preparation of water solution of salts of oxidisers and fuel phase, which consists of fuel and emulsifier, and mixing of obtained water solution of salts of oxidisers and obtained fuel phase in static mixer. Water solution of salts of oxidisers is prepared by mechanical mixing, exposure to ultraviolet waves with frequency 18-150 kHz by means of submerged metal waveguides and recirculation of flow through ultrasonic flow disperser with frequency of ultrasonic waves 18-150 kHz. Fuel phase is prepared with flow recirculation. Obtained mixture of water solution of salts of oxidisers and fuel phase is dispersed in ultrasonic flow disperser with frequency of ultrasonic waves 18-150 kHz. Also claimed is device for said method realisation.

EFFECT: reduction of energy consumption of production of water in oil type emulsion and increase of detonation ability of explosives which contain such emulsion.
