Embodiment 1
[0030] Example 1 Exemplary Production Method of Corncob Granular Carbon
[0031] This example exemplarily describes the method of producing corn cob granular carbon using the semi-closed granular carbonization furnace described in the Chinese invention patent No. ZL200710086505.4, including material selection, material processing, furnace charging carbonization, cooling out of the furnace, Steps such as metering and packing, but not limited thereto.
[0032] Material selection: Naturally air-dry the corncobs of agricultural and sideline products to reduce the water content to below 20%.
[0033] Material processing: use any crushing method in the prior art to process and crush the above-mentioned qualified corncobs, and the diameter of the crushed corncobs is 2-10mm. The crushed corn cob particles can be sieved, and the corn cob particles that do not meet the requirements can be reprocessed.
[0034] Furnace charging and carbonization: put the processed corncob particles int...
Embodiment 2
[0038] Example 2 The production process of carbon-based protected land soil conditioner
[0039] 600 kg of biomass granular carbon, 70 kg of calcium superphosphate, 5 kg of potassium dihydrogen phosphate, 80 kg of shell powder, 4.5 kg of chitosan, 70 kg of sodium nitrophenolate, 100 kg of zeolite powder, ferrous sulfate (containing iron 20%) of 0.5 kg and 70 kg of humic acid are mixed, and ZLC-300 mixer and KP-300 organic fertilizer granulator are used for pressure granulation, and other types of mixers and granulators can also be used for mixing and granulation.
[0040] Described calcium superphosphate, potassium dihydrogen phosphate, shell powder, chitosan, sodium nitrophenolate, zeolite powder, ferrous sulfate, humic acid are all available on the market, and are all sold in agricultural material stores. It is a commonly used material in agriculture.
