Embodiment 1

[0023] The technological process of this embodiment is as follows:

[0024] ①Concentrate the MSG waste liquid, and concentrate the solid content from 8% to 30%, which is called the concentrated liquid;

[0025] ② Potassium chloride and sulfuric acid are proportioned in a molar ratio of 1: 1.05, and steam is introduced to react at 120° C. to generate potassium bisulfate and hydrogen chloride gas, and the hydrogen chloride gas is absorbed into 31% industrial hydrochloric acid by water;

[0026] ③ The concentrated solution is mixed by 70% and potassium bisulfate by 30%, which is called mixed acid;

[0027] ④ neutralize the mixed acid and gaseous ammonia, control the degree of neutralization at 1.1, and the neutralized material is called feed liquid;

[0028] ⑤ Add trace element compounds to the feed liquid, the ratio is 85% feed liquid, 5% magnesium sulfate, 3% zinc sulfate, 3% borax, 2% manganese sulfate, 2% ferrous sulfate, this fertilizer is the finished product with high nit...

Embodiment 2

[0030] The technological process of this embodiment is as follows:

[0031] ① Concentrate the waste liquid of monosodium glutamate, and concentrate the solid content from 8% to 35%, which is called concentrated liquid;

[0032] ② Potassium chloride and sulfuric acid are proportioned in a molar ratio of 1: 1.05, and steam is introduced to react at 125° C. to generate potassium bisulfate and hydrogen chloride gas, and the hydrogen chloride gas is absorbed into 31% industrial hydrochloric acid by water;

[0033] ③ The concentrated solution is mixed by 80% and potassium bisulfate by 20%, which is called mixed acid;

[0034] ④ neutralize the mixed acid and gaseous ammonia, control the degree of neutralization at 1.2, and the neutralized material is called feed liquid;

[0035] ⑤ Add trace element compounds to the feed liquid, the ratio is 90% feed liquid, 1% magnesium sulfate, 2% zinc sulfate, 2% borax, 1% manganese sulfate, 3% ferrous sulfate, this fertilizer is the finished prod...

Abstract

The invention discloses a method for producing a chelated organic potassium sulfate liquid flush fertilizer by using monosodium glutamate wastewater, which comprises the following steps: (1) concentrating the monosodium glutamate wastewater; (2) mixing potassium chloride and sulfuric acid according to a molar ratio, introducing vapor, and reacting to obtain potassium bisulfate and hydrogen chloride gas; (3) mixing the concentrated solution 70 to 90% with the potassium bisulfate 10 to 30%; (4) carrying out a neutralization reaction of mixed acid and gaseous ammonia and controlling the neutralization degree at 1.1 to 1.3; and (5) adding trace element compounds including magnesium sulfate, zinc sulfate, borax, manganese sulfate and ferrous sulfate. The method can transform potassium chloride fertilizer into potassium sulfate fertilizer and fully utilize amino acids and organic matters in the monosodium glutamate to chelate with trace elements added therein such as magnesium, zinc, boron, iron and manganese. The fertilizer is a full-nutrition liquid fertilizer to overcome the disadvantages of potassium sulfate solid fertilizer that cannot produce high-nitrogen and high-potassium additional fertilizer, and is specifically suitable for drip irrigation.

Description

technical field [0001] The invention relates to a method for producing agricultural fertilizers, in particular to a method for fertilizing by using monosodium glutamate waste liquid to produce potassium sulfate organic type chelating liquid. Background technique [0002] Monosodium glutamate waste mother liquor is a kind of high-concentration organic wastewater, which pollutes the environment very much. The waste mother liquor contains rich nutrients, which can be comprehensively utilized to produce feed protein, ribonucleic acid, organic compound fertilizer, agricultural fungicides and recycled nutrients, etc., reaching The dual effects of governance and comprehensive utilization. [0003] Document retrieval result shows, the document report that utilizes monosodium glutamate waste liquid to produce organic-inorganic compound fertilizer is more common in China, as: " organic-inorganic compound fertilizer and production method thereof produced by monosodium glutamate tail li...
