Embodiment 1

[0061] The agricultural and forestry biomass raw materials in this example are rice straw and corn straw, the mass ratio is 3:7, the moisture content is 17.5%, and the total is 100kg.

[0062] Production methods for carbon-based liquid fertilizers include:

[0063] (1) Pretreatment: crush the straw to a length of 10-20cm.

[0064] (2) Carbonization: send the crushed straw in step (1) into a regenerative rotary bed carbonization furnace, wherein the carbonization temperature is 600° C., and the carbonization time is 40 minutes. The high-temperature oil and gas produced by carbonization are transported to the high-temperature oil-gas separation system through the pipeline. The biochar produced by carbonization is 28.5kg, which enters the leaching system after being discharged by the double helix.

[0065] (3) High-temperature oil-gas separation: Pass the high-temperature oil-gas generated in step (2) into the oil-gas separation system, cool it with water, and separate out 41.8...

Embodiment 2

[0072] The agricultural and forestry biomass raw materials in this embodiment are rice husk and reed, the mass ratio is 7:3, and the average moisture content is 8.7%, totaling 100kg.

[0073] Production methods for carbon-based liquid fertilizers include:

[0074] (1) Pretreatment: crush the reed stalks to a length of 10-20 cm.

[0075] (2) Carbonization: Send the reed straw and rice husk crushed in step (1) into a regenerative rotary bed carbonization furnace, where the carbonization temperature is 450°C and the carbonization time is 45 minutes. The high-temperature oil and gas produced by carbonization are transported to the high-temperature oil-gas separation system through the pipeline. The biochar produced by carbonization is 22.5kg, which enters the leaching system after being discharged by the double screw.

[0076] (3) High-temperature oil-gas separation: Pass the high-temperature oil-gas generated in step (2) into the oil-gas separation system, cool it with water, a...

Embodiment 3

[0083] The agricultural and forestry biomass raw material of this embodiment is bagasse, with a moisture content of 17.2%, and a total of 100kg.

[0084] Production methods for carbon-based liquid fertilizers include:

[0085] (1) Carbonization: Bagasse is sent into a regenerative rotary bed carbonization furnace, where the carbonization temperature is 700°C and the carbonization time is 30 minutes. The high-temperature oil and gas produced by carbonization are transported to the high-temperature oil-gas separation system through the pipeline. The biochar produced by carbonization is 25.5kg, which enters the extraction system after being discharged by the double screw.

[0086] (2) High-temperature oil-gas separation: Pass the high-temperature oil and gas generated in step (1) into the oil-gas separation system, cool it with water, and separate out 42.9kg of pyrolysis gas, 4.4kg of pyrolysis oil and 27.2 kg of wood vinegar kg. Among them, a part (24.9kg) of the generated py...

Abstract

The invention relates to a carbon-based liquid fertilizer. The carbon-based liquid fertilizer is prepared from the following components in parts by weight: 1 to 3 parts of wood vinegar, 2 to 6 parts of a biomass charcoal extract, 1 to 2 parts of biogas slurry, 0.5 to 3 parts of a suspending concentrate, 3 to 8 parts of a nitrogen-phosphorus-potassium fertilizer, 1 to 3 parts of potassium humate, 0.5 to 2 parts of alginic acid, 0.5 to 2 parts of chitin and 0.5 to 2 parts of amino acid. The invention also relates to a system and a method for production of the carbon-based liquid fertilizer. Through application of the carbon-based liquid fertilizer, the yield of a crop is more obviously improved, and the usage amount of a chemical fertilizer can be effectively reduced.

Description

technical field [0001] The present invention generally relates to the technical field of agricultural resource utilization, in particular to a carbon-based liquid fertilizer, its production system and method. Background technique [0002] At present, agriculture has entered the period of modernization, and the development of modern agriculture must equip modern agriculture with modern agricultural assets. Increasing fertilizer application is an important link to ensure increased grain production and the quality and safety of agricultural products. Fertilizers used in agriculture are mainly divided into chemical fertilizers (ie chemical fertilizers) and organic fertilizers. Chemical fertilizers are man-made fertilizers using chemical and physical methods. They contain one or several nutrients needed for crop growth. Long-term use will easily lead to damage to the soil structure, reduced production potential, increased metals and toxic elements, and reduced microbial activity...
