Embodiment 1

[0023] Embodiment 1: carbonization of rape straw

[0024] Collect rape stalks, dry them in the sun, cut the rape stalks into small pieces below 10cm, dehumidify them on the top of the carbonization furnace, and then enter the pyrolysis pool. The pyrolysis temperature in the decomposing pool is 350°C, and the pyrolysis time is 70 minutes. After the pyrolysis is completed, the charcoal is stuffed. The charcoal stuffing time is 10 minutes, and then cooled to 100-200°C to produce charcoal. Each ton of rape straw (dry weight) can get 300kg of carbonized material, 210kg of vinegar liquid, 18kg of tar, and 650m of combustible gas 3 .

[0025] The carbonization furnace of the present invention can use the application number 201320368810.3 as a crop straw carbonization device, figure 1 A schematic structural diagram of the device is shown, and the crop straw carbonization device is mainly composed of a pyrolysis tank 1, which is a tower-type pyrolysis tank. In order to facilitate in...

Embodiment 2

[0026] Embodiment 2: the carbonization of edible mushroom residue

[0027] Collect edible fungus slag, dry it in the sun, cut the edible fungus slag into small pieces below 10cm, dehumidify on the top of the carbonization furnace, and then enter the pyrolysis pool. Yes; the pyrolysis temperature in the pyrolysis pool is 380°C, and the pyrolysis time is 70 minutes. After the pyrolysis is completed, the charcoal is stuffed. The charcoal stuffing time is 10 minutes, and then cooled to 100-200°C to produce charcoal. For each ton of edible fungus residue (dry weight), 360kg of carbonized material, 230kg of vinegar liquid, 8kg of tar, and 600m of combustible gas can be obtained. 3 .

Embodiment 3

[0028] Example 3: Carbonization of forestry residues

[0029] Collect forestry residues, dry them in the sun, cut the forestry residues into small pieces below 10cm, dehumidify them on the top of the carbonization furnace, and then enter the pyrolysis pool. Yes; the pyrolysis temperature in the pyrolysis pool is 300°C, and the pyrolysis time is 70 minutes. After the pyrolysis is completed, the charcoal is stuffed. The charcoal stuffing time is 10 minutes, and then cooled to 100-200°C to produce charcoal. For each ton of forestry residues (dry weight), 330kg of carbonized material, 250kg of vinegar liquid, 30kg of tar, and 700m of combustible gas can be obtained 3 .

Abstract

The invention discloses a method for rapidly and continuously carbonizing agricultural straws. The method comprises the following steps of cutting straws up, putting into a carbonization furnace, dehumidifying the straws at the top of the carbonization furnace, then feeding into a pyrolysis pool, pyrolyzing and carbonizing at 300-400 DEG C, and then smouldering carbon, cooling and discharging the carbon after pyrolysis and carbonization are finished. According to the method, before pyrolysis, the straws are dehumidified through heat generated by a pyrolyzing furnace, so that energy consumption is saved, and the equipment for dehumidification is not required, furthermore, dehumidification and pyrolysis can be finished in continuous steps, the step of dehumidifying the straws and then transferring into the pyrolyzing furnace for pyrolysis is eliminated, both steps and energy source are saved; after carbonization of every ton of straw raw material (by dry weight), 300kg-360kg of carbide, 200kg-260kg of vinegar, 8kg-30kg of tar and 600-750m<3> of combustible gas can be obtained.

Description

technical field [0001] The invention belongs to the field of straw pyrolysis, in particular to a method for continuous and rapid carbonization of agricultural straw. Background technique [0002] Carbonization of agricultural straw is the key to the development and utilization of agricultural straw resources. At present, straw carbonization on the market, first, only a small amount of straw scraps are mixed in the process of biomass carbonization, and straw carbonization cannot be completely used to obtain straw carbonization materials; second, the temperature in carbonization is difficult to control, resulting in low utilization rate of straw There are large differences in stable quality and low output, and the problem of a large amount of existing agricultural straw storage cannot be quickly solved. Moreover, the carbonized product prepared by the existing carbonization method has high ash content, low carbonized product yield, slow carbonization speed, and high equipment...
