FIELD: wood-working industry, in particularly, means of impregnation of wood fallings with protective compositions. ^ SUBSTANCE: the wood is placed in the installation body near the electrode-radiation source, the impregnation liquid is sprayed for delivery to the wood, and an electromagnetic action is accomplished on it on the wood by single-pole electromagnetic pulses at a power of at least 1 MW, duration less than 1 NS and repetition frequency of at least 1 kgHz. The installation for wood impregnation has a body, electrode connected to the source of electromagnetic action and a vessel for the impregnation liquid, the electrode is positioned is the center of the body and serves as the radiation source, a device for spraying of the impregnation liquid is positioned in the upper part of the body, it represents a circular collector with nozzles connected through a pump to the vessel for the impregnation liquid. A grate-holder is positioned in the lower part of the body for vertical disposition of the wood between the body walls and the electrode-radiation source, and under the device for spraying of the impregnation liquid the body bottom is provided with an opening for rejection of the surplus impregnation liquid connected to the filter installed outside the body and through the second pump-to the vessel for the impregnation liquid, the source of electromagnetic action represents a generator of nanosecond pulses with a duration of less than 1 ns, power of at least 1 MW and repetition frequency of at least 1 kHz. ^ EFFECT: simplified method of wood impregnation and installation for its realization, provided a high quality of impregnation. ^ 2 cl, 1 dwg |
