Abstract

The invention relates to an online humic acid high-temperature rapid activation shotcrete device and a shotcrete process, and belongs to the technical field of activated humic acid compound fertilizer. An online humic acid high-temperature rapid activation spraying device, comprising a first mixing reaction pool and a second mixing reaction pool, the first mixing reaction pool and the second mixing reaction pool are connected through an upper port and a lower port, and the second mixing reaction pool A baffle plate is arranged in front of the outlet of the upper passage in the pool, a feeding port is arranged on the upper part of the first mixing reaction pool, and a discharging device is arranged in the second mixing reaction pool. A venturi tube is arranged inside the feeding port, and a tee is arranged above the venturi tube. A flow stabilizer is arranged above the interior of the first mixing reaction tank. The discharging device is F-shaped, the opening direction of the air inlet in the horizontal direction is away from the upper port, the feeding port is located below the air inlet and the opening direction is the same, and the air inlet and the feeding port are respectively connected with the discharging pipe, The other end of the discharge pipe is provided with an atomizing nozzle.

Description

technical field [0001] The invention relates to an online humic acid high-temperature rapid activation spraying device and a spraying process, and belongs to the technical field of activated humic acid compound fertilizer. Background technique [0002] Activated humic acid can improve soil structure, stimulate crop growth, improve crop quality, improve fertilizer utilization, and improve crop disease resistance. The use of activated humic acid can promote the scientific and rational fertilization of my country's agriculture, serve modern agriculture, provide crops with a reasonable diet, improve crop immunity, reduce crops' dependence on pesticides, achieve zero growth in the use of chemical fertilizers and pesticides, ensure food security, and allow farmers to continue to increase production increase income. According to statistics, the reserves of humic acid in weathered coal, lignite and peat in my country are only more than 200 billion tons, and the number of humic acid ...

AI Technical Summary

Problems solved by technology

[0003] At present, conventional humic acid activation methods include oxidation activation, alkalization activation, etc., all of which undergo a series of process equipment such as activation extraction, solid-liquid separation, evaporation and drying under liquid phase conditions, which have cumbersome processes, high energy consumption, and pollution. Large, high cost and other disadvantages, and the conventional activation methods are mostly carried out at normal temperature and pressure, the reaction time and production cycle are long, the activation effect is poor, the activation performance of the product is low, and the application is inconvenient. Therefore, it is urgent to find A humic acid activation method and device more conducive to production
