Problems solved by technology

[0005] For the above-mentioned deficiencies that exist in the prior art, the purpose of the present invention is to provide a kind of high-tower production process for the production of nitro-fulvic acid compound fertilizer, to solve the existing high-tower nitro-compound fertilizer production process, because the high-tower is high temperature Melting and mixing, nitrate nitrogen is easy to decompose and release oxygen when heated at high temperature, and can form an explosive mixture when mixed with reducing agents, organic substances, flammable substances such as sulfur, phosphorus or metal powder, which can explode when heated rapidly, posing a safety hazard , and it is difficult to realize the problem of producing nitro compound fertilizer rich in fulvic acid

Abstract

The invention provides a process method for producing a nitro fulvic acid compound fertilizer by virtue of a high tower. The compound fertilizer is prepared by virtue of a high-tower fusion-spraying granulation equipment system. The process method specifically comprises the steps of dissolving, mixing, reacting, granulating, cooling, sieving and enveloping, so as to obtain the finished nitro fulvic acid compound fertilizer. According to the process method, the problem that organic matters such as fulvic acid cannot be heavily added in the existing high-tower production process of the compound fertilizer is solved; and by utilizing novel raw materials and process, the effective content of fulvic acid in the nitro fulvic acid compound fertilizer produced by virtue of the high tower is more than or equal to 3.5%. The compound fertilizer produced by virtue of the process method contains the following components in parts by weight: 30-80 parts of a nitro-nitrogen fertilizer, 8-40 parts of a phosphate fertilizer, 0-50 parts of a potassium fertilizer and 9-25 parts of vitality elements. The compound fertilizer contains rich elements such as nitrogen, phosphorus and potassium, is capable of activating soil, can be directly absorbed and utilized by soil and can meet diversities of types, numbers and proportions of nutrients required by different crops.

Description

technical field [0001] The invention relates to the field of agricultural compound fertilizer production, in particular to a process method for producing nitrofulvic acid compound fertilizer in a high tower and the compound fertilizer. Background technique [0002] With the saturation of the overall domestic chemical fertilizer production capacity, the differentiation of compound fertilizer products in the market has become increasingly prominent, and the types of special compound fertilizers suitable for crop growth and development have gradually increased. However, the compound fertilizer market has also been affected to a large extent. The production and application of chemical fertilizers in the country are constantly increasing. Increased application of chemical fertilizers has played an important role in the development of agricultural production. The cost of fertilizers has increased, the utilization rate of chemical fertilizers has decreased, soil salinization, soil ...
