Embodiment 1

[0030] Embodiment 1: The production steps of utilizing tobacco waste to produce organic water-soluble fertilizer are as follows:

[0031] (1) The method of obtaining the tobacco leachate is: collecting and filtering the waste liquid produced in the production of cigarettes. The waste liquid is first soaked in alcohol to dissolve the organic matter such as fructose and amino acids, and then distill and recover the alcohol. The rest is tobacco Leachate.

[0032] (2) Sterilize the tobacco leach solution at 100° C. for 40 minutes in an enamel reaction kettle, and concentrate to form a base solution rich in organic matter and potassium, with a moisture content of 70%;

[0033] (3) Heat up to 130°C, add 12% boric acid and 6% zinc sulfate according to the mass of the base solution, stir at a speed of 480r / min, stir for 2.5h, and completely dissolve the chelate;

[0034](4) measure the pH value, adjust the pH value to pH equal to 6.5 with ammonia water;

[0035] (5) Grind with a col...

Embodiment 2

[0037] Embodiment 2: The production steps of utilizing tobacco waste to produce organic water-soluble fertilizer are as follows:

[0038] (1) The method of obtaining the tobacco leachate is: collecting and filtering the waste liquid produced in the production of cigarettes. The waste liquid is first soaked in alcohol to dissolve the organic matter such as fructose and amino acids, and then distill and recover the alcohol. The rest is tobacco Leachate.

[0039] (2) Sterilize the tobacco leach solution at 121° C. for 30 minutes in an enamel reaction kettle, and continue to concentrate after dropping the temperature to form a base solution rich in organic matter and potassium, reaching a moisture content of 60%;

[0040] (3) Heat up to 130°C, add 15% boric acid and 10% magnesium sulfate according to the mass of the base solution, stir at a speed of 560r / min, stir for 3h, and completely dissolve the chelate;

[0041] (4) measure the pH value, adjust the pH to pH equal to 6.0 with...

Embodiment 3

[0043] The appearance of the obtained organic water-soluble fertilizer is a brownish-yellow liquid with a sweet smell of tobacco. The content of organic matter exceeds 200g / L, the content of nitrogen, phosphorus and potassium exceeds 100g / L, the content of boron exceeds 25g / L, and the content of magnesium exceeds 20g / L. L, very suitable for drip fertigation in agriculture. The dosage is 3-10kg per mu, so that the crops will turn green quickly, the sweetness of the crops will increase, and the yield will increase significantly. Embodiment 3: The production steps of utilizing tobacco waste to produce organic water-soluble fertilizer are as follows:

[0044] (1) The method of obtaining the tobacco leachate is: collecting and filtering the waste liquid produced in the production of cigarettes. The waste liquid is first soaked in alcohol to dissolve the organic matter such as fructose and amino acids, and then distill and recover the alcohol. The rest is tobacco Leachate.

Abstract

The invention discloses a medium and trace element-containing organic water-soluble fertilizer produced from tobacco wastes. The medium and trace element-containing organic water-soluble fertilizer produced from tobacco wastes is produced through the following steps: 1, collecting and filtering a tobacco alcohol leachate generated in the production process of cigarettes; 2, sterilizing and concentrating the tobacco leachate at 100-121 DEG C to form a substrate liquid being rich in organic matters and containing potassium; 3, heating the substrate liquid to 130 DEG C, adding a medium and trace element source, stirring the liquid and the source at 480-560 r / min for 2-3 h until the source is completely dissolved and chelated, and adjusting the pH value of the obtained solution; and 4, grinding the above obtained solution, and allowing the ground solution to stand for removing bubbles. The tobacco leachate wastes are used to produce the novel organic water-soluble fertilizer, so the environmental protection problem in tobacco production is fundamentally solved, sewage discharge is avoided, complete recycling of the wastes generated in the production process of the cigarettes is realized, zero pollution discharge is realized, and a new high-value utilization technology for changing the tobacco wastes into valuables is developed.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a tobacco organic water-soluble fertilizer. Background technique [0002] my country's tobacco planting area and output rank first in the world, and about 25% (901.5 million tons) of unsuitable tobacco dust, tobacco stems and tobacco extracts are produced in the annual tobacco leaf processing. Bring serious pollution and harm to the environment, and also cause a waste of resources. These wastes cannot be used for cigarette production, and are usually discarded, incinerated and discharged at will; some enterprises reuse their wastes by extracting nicotine, solanesol, vegetable protein, ethanol or nicotinamide, etc. However, most of these methods remain in the experimental stage and have not been widely promoted in industrialization; because tobacco waste contains bioorganic components and secondary metabolites such as fructose, protein, amino acids, and nicotine, as well as a large amou...
