METHOD AND COMPLEX FOR OZONE TREATMENT OF GRAIN, SEEDS, AND ROOMS Russian patent published in 2008 - IPC A01C1/00 

FIELD: agriculture.

SUBSTANCE: method involves providing perforated pipeline before treatment of grain or seed mass placed within closed volume or rooms; producing ozone-and-gas mixture; blowing ozone-and-gas mixture via perforated pipeline through grain or seed mass or through rooms; after termination of blowing process, withdrawing secondary ozone-and-gas mixture for recycling; providing perforated pipeline by successively joining n-number of successively lowered perforated pipes, with pipe sizes increasing in the course of flow of ozone-and-gas mixture. Primary treatment of objects is effectuated using ozone-and-gas mixture produced by mixing ozone-and-oxygen mixture generated in ozonizing unit with carrier-gas, with pressure and concentration desired for treatment being provided. When secondary ozone-and-gas mixture is used for treatment of objects, said mixture is fed for mixing with newly produced ozone-and-gas mixture after delivery of the latter from ozonizing unit in the volume desired for maintaining constant ozone concentration in ozone-and-gas mixture for treatment of objects. Upon termination of treatment process, excessive ozone-and-gas mixture is decomposed in decomposer. Concentration of ozone is 90-200 g/m³. Complex has perforated pipeline, ozonizing unit and discharge pipe communicating with exhaust fan whose outlet is provided in roof or side walls delimiting volume above grain and seed mass or rooms. Complex also has device for mixing of ozone with atmospheric air, device for preparing of secondary ozone-and-gas mixture, and decomposer. Ozonizing unit consists of oxygen generator, ozone generator, high-frequency high-voltage power source and refrigerating machine. Outlet of ozonizing unit is connected to first inlet of mixing device including pressure fan. Outlet of mixing device is connected to perforated pipe. Outlet of exhaust fan is connected to inlet of device for preparing of secondary ozone-and-gas mixture and to inlet of destructor. Outlet of secondary mixture preparing device is connected to second inlet of mixing device.

EFFECT: increased efficiency in treatment of grain or seed and rooms with ozone-and-gas mixture.
