Abstract

The invention discloses a method and system for preparing a green nitrogen fertilizer by adopting plasmas. The method comprises the steps that collected energy is distributed and used for driving loaded energy to generate the plasmas through boosting, and the plasmas discharge electricity to generate oxynitrides; the oxynitrides are subjected to compression dissolution in absorption liquid to generate the nitrogen fertilizer. The system comprises an energy collecting device, an energy control device, an energy storage device, a boosting device and a nitrogen fertilizer generating device, and the nitrogen fertilizer generating device comprises a plasma generating module, a compression module and an absorption module. According to the method, renewable energy is taken as the drive by combining energy storage and control, compressed air is adopted for fully dissolving NOx generated from discharging of the plasmas, safe operation is ensured, and the nitrogen fixing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of plasma technology, and more specifically relates to a method and system for preparing green nitrogen fertilizer by plasma. Background technique [0002] Nitrogen is an indispensable element in the plant growth cycle and plays a vital role in the synthesis of chlorophyll in the green leaves and green stems of plants. Traditional agriculture uses chemical fertilizers to supplement the required nitrogen fertilizers. The use of chemical fertilizers increases agricultural costs and causes soil acidification and compaction, which affects the survival of soil microorganisms, not only destroys the soil fertility structure, but also reduces fertilizer efficiency. [0003] Atmospheric pressure plasmas are rich in energetic electrons, free radicals and other reactive species. These active ingredients collide and interact with each other, so that the free nitrogen in the normal state exists in the form of nitrogen oxides NOx ...
