Abstract
As a result of the improvement of the irrigation system with the purification of exhaust gases with subsequent activation of irrigation water with carbon dioxide, it will allow us to abandon significant structural elements developed in the previous similar irrigation system, such as a compressor for pumping air and a mixer for saturating irrigation water with purified carbon dioxide, which will reduce the cost and simplify the low-volume irrigation system during its further operation.
Introduction.In the Volgograd region, up to 10% of arable land falls on saline soils. Russian and foreign scientists have proved what a positive effect carbon dioxide (CO2) has on improving the soil structure.
Object. The object of the study is the principle of purification of diesel engine exhaust gases from exhaust gases from toxic substances by means of an oxidizing catalyst and the mode of intake of purified gas with its supply to the irrigation system to activate irrigation water with subsequent delivery to water outlets, thereby ensuring its solubility in the soil for reclamation of salt pans.
Materials and methods. The research material was the structural elements of the drip irrigation system and a separate device installed in the irrigation system for cleaning exhaust gases by means of an oxidizing catalyst with subsequent activation of irrigation water with purified carbon dioxide. The development of the theoretical foundations of the solonetz process by K.K. Gedroits was used, in the formation of unfavorable water-physical and chemical properties, to establish the leading role of exchange-absorbed sodium in solonetzic soils.
Results and conclusions. The introduction of an oxidizing catalyst into the design of the irrigation system will make it possible to clean the exhaust gases from toxic substances. After passing through the oxidizing catalyst, the exhaust gases react with precious metals located in the ceramic cells of the catalyst device, the exhaust gases are converted into carbon dioxide and water (CO2 + H2O). Then the purified carbon dioxide is mixed with irrigation water during water intake and transported to distribution and irrigation pipelines and fed into the soil.
