Method for manufacturing carbon and carbon fertilizers by aid of straw

[0032] Example 1

[0033] Method for preparing charcoal and charcoal fertilizer from straw , Including the following steps:

[0034] 1) Put Straw Crush to a length of 50-55mm, and let stand for 24h;

[0035] 2) After crushing the above Straw Compressed into lumps to make the resulting Straw The moisture content in the block is ±0.2g / cm 3 ;

[0036] 3) Combine the gains in step 2) Straw The blocks are laid in the open carbonization kiln to ensure that Straw The upper surface of the block is flat to avoid raw material vacancies and make Straw Block filling the carbonization kiln while at the same time Straw The upper surface of the block is covered with a layer of 4cm thick scraps; first, evenly arrange the ignition positions on the upper surface of the scraps. When ignition, first point the carbonization kiln near the periphery of the carbonization kiln wall, and turn on the induced draft fan to control the carbonization kiln. Oxygen supply, after 30 minutes of ignition of the su

[0043] 2) After crushing the above Straw Compressed into lumps to make the resulting Straw The moisture content in the block is ±0.2g / cm 3 .

[0044] 3) Combine the gains in step 2) Straw The blocks are laid in the open carbonization kiln to ensure that Straw The upper surface of the block is flat to avoid raw material vacancies and make Straw Block filling the carbonization kiln while at the same time Straw The upper surface of the block is covered with a layer of 4-6cm thick scraps; first, evenly arrange the ignition positions on the upper surface of the scraps, and then point the carbonization kiln near the circumference of the carbonization kiln wall during ignition, and turn on the induced draft fan to control the carbonization kiln during ignition. The amount of oxygen supply

[0048] Example 3

[0049] Repeat Example 2, the difference is that the gibberellin is replaced with triiodobenzoic acid, and other conditions remain unchanged to obtain a carbon-based active organic fertilizer. According to the detection method of NY798-2004-T, the moisture content of the obtained carbon-based active organic fertilizer is 0.02%, the pH is 6, and the organic matter content is 66%.
