[0034] Such as figure 1 As shown, an equipment for producing liquid fertilizer by using concentrated biogas slurry, the equipment includes concentrated biogas slurry storage tank 1, complexing kettle 2, synthesis kettle 3, stabilization kettle 4, pulverizer 5, primary stirring tank 6, colloid mill 7, secondary mixing tank 8, homogenizer 9, fertilizer storage tank 10 and filling machine 11; the storage tank 1 is connected with the complexing kettle 2, and the complexing kettle 2 is connected with the synthesis kettle 3 through a precision filter, The pulverizer 5 is connected to the synthesis kettle 3, the synthesis kettle 3 is connected to the stabilization kettle 4 through a precision filter, the stabilization kettle 4 is connected to the first-stage stirring tank 6 through a precision filter, and the first-stage stirring tank 6 and the second-stage stirring tank 8 are set in the middle The colloid mill 7 and the secondary mixing tank 8 are connected to the homogenizer 9, and...

Embodiment 2

[0054] 40 to 60 parts of the concentrated biogas slurry in the concentrated biogas slurry storage tank 1 are first brought into the complexing tank 2, the stirring mechanism 2-1 of the complexing tank is started, and the pH is stabilized between 5.5 and 6.5 by adding an acid-base regulator. Control the temperature in the kettle to 60°C. After stabilization, it is discharged into the synthesis kettle 3 through the precision filter 2-2 of the complexation kettle; the stirring mechanism 3-1 of the synthesis kettle is started, and the chelating agent and plant growth regulator are first put in, and then the urea, nitric acid Ammonium, potassium nitrate, calcium nitrate tetrahydrate, ammonium dihydrogen phosphate, magnesium sulfate heptahydrate, ferrous sulfate, zinc sulfate, borax, ammonium molybdate, manganese sulfate, and copper sulfate are pulverized by the pulverizer 5 and added to the synthesis kettle 3 in turn During the process, control the temperature in the kettle to 60°C ...

Embodiment 3

[0059] Each component of liquid fertilizer of the present invention is by weight: (every part is 1kg)

[0060] 40 parts of concentrated biogas slurry, 2 parts of urea, 1 part of ammonium nitrate, 5 parts of potassium nitrate, 0.2 parts of calcium nitrate tetrahydrate, 3 parts of ammonium dihydrogen phosphate, 0.2 parts of magnesium sulfate heptahydrate, 0.1 part of ferrous sulfate, 0.05 parts of zinc sulfate 0.05 part of borax, 0.005 part of ammonium molybdate, 0.05 part of manganese sulfate, 0.05 part of copper sulfate, 0.01 part of plant growth regulator, 0.005 part of chelating agent, 0.01 part of acid-base regulator, 0.01 part of deodorant, 0.005 part of fungicide parts, 0.001 parts of defoamer.

[0061] Others are the same as embodiment 1 or 2.

Abstract

The invention relates to equipment for producing liquid fertilizer through concentrated biogas slurry and a method for producing liquid fertilizer. The equipment comprises a storage tank, a complexing kettle, a synthesizing kettle, a stabilizing kettle, a smashing machine, a stirring tank, a colloid mill, a homogenizer, a fertilizer storage tank and a filling machine. The method for producing the liquid fertilizer mainly comprises the steps of adjusting acidity of the concentrated biogas slurry, removing heavy metal and then chelating to manufacture the liquid fertilizer favorable for crops to absorb. The liquid fertilizer is prepared from the following ingredients in a formula in parts by weight: 40 to 60 parts of concentrated biogas slurry, 2 to 6 parts of urea, 1 to 4 parts of ammonium nitrate, 4 to 12 parts of potassium nitrate, 0.2 to 0.5 part of calcium nitrate terahydrate, 3 to 6 parts of ammonium dihydrogen phosphate, 0.2 to 0.5 part of magnesium sulfate heptahydrate, 0.1 to 0.2 part of ferrous sulfate, 0.05 to 0.1 part of zinc sulfate, 0.05 to 0.08 part of borax, 0.005 to 0.1 part of ammonium molybdate, 0.05 to 0.1 part of manganese sulfate, 0.05 to 0.1 part of copper sulfate, 0.01 to 0.01 part of plant growth regulator, 0.005 to 0.01 part of chelating agent, 0.01 to 0.03 part of acid-base regulator, 0.001 to 0.001 part of deodorant, 0.005 to 0.01 part of sterilizing agent and 0.001 to 0.002 part of defoaming agent. The liquid fertilizer has the advantages of scientific and reasonable formula, simple manufacture and very obvious application effect.

Description

technical field [0001] The invention relates to a device for producing liquid fertilizer and a method for producing liquid fertilizer, in particular to a device for producing liquid fertilizer by using concentrated biogas slurry and a method for producing liquid fertilizer. Background technique [0002] At present, biogas slurry concentration is an effective, harmless and resourceful measure for biogas slurry in large-scale biogas projects. It mainly uses technical means such as sedimentation, filtration, and membrane treatment to reduce the number of large amounts of turbid and unusable biogas slurry, and double the concentration; after concentration, the biogas slurry is clear, odorless, and has good fluidity and good commerciality. Become a liquid nutrient directly used by crops; concentrated biogas slurry contains a large number of beneficial small molecular organic substances, such as amino acids, fulvic acids, nucleic acids, monoacids, cellulose and other active substa...
