Problems solved by technology

[0004] In southern Jiangxi, a large number of dead cedar bark and dead navel orange tree raw materials are discarded on the mountain and have not been fully utilized. Some rot on the mountain, and some are picked up by farmers and directly used as firewood at home, seriously polluting the environment

Embodiment 1

[0017] A preparation method of a novel environmentally friendly biochar includes the following steps:

[0018] (1) Raw material selection: select bamboo chips, wood chips, cedar bark, orange tree decay, and other biological waste materials. Bamboo chips account for 15% of the total raw materials, and cedar bark accounts for 5% of the total raw materials. The proportion of total raw materials is 4%;

[0019] (2) Mixing and screening: all raw materials are mixed and crushed, and then sent to a suspended vibrating classifier for screening and classification, retaining 2-7mm particles;

[0020] (3) Drying and separation: The screened materials enter the tumble dryer, after being dried by an open flame, they are separated by an induced draft fan to extract light particles for use and remove heavy particles. The fan flow rate is 25000-35000m. 3 / h, speed 1000r / min, total pressure 1800~1300Pa;

[0021] (4) High-pressure forming: the granules that are dehydrated and dried are fed into a high-...

Embodiment 2

[0025] A preparation method of a novel environmentally friendly biochar includes the following steps:

[0026] (1) Selection of raw materials: select bamboo chips, wood chips, cedar bark, orange tree shavings, and other biological waste materials. Bamboo chips account for 18% of the total raw materials, and cedar bark accounts for 4% of the total raw materials. Both account for 5% of the total raw materials;

[0027] (2) Mixed screening: All raw materials are mixed and crushed, and then sent to a suspended vibration classification screening machine for screening and classification, retaining 2-7mm particles;

[0028] (3) Drying and separation: The screened materials enter the tumble dryer, after being dried by an open flame, they are separated by an induced draft fan to extract light particles for use and remove heavy particles. The fan flow rate is 25000-35000m. 3 / h, speed 1000r / min, total pressure 1800~1300Pa;

Embodiment 3

[0033] A preparation method of a novel environmentally friendly biochar includes the following steps:

[0034] (1) Selection of raw materials: select bamboo chips, wood chips, cedar bark, orange tree shavings, and other biological wastes. Bamboo chips account for 20% of the total raw materials, and cedar bark accounts for 5% of the total raw materials. Both account for 5% of the total raw materials;

[0035] (2) Mixed screening: All raw materials are mixed and crushed, and then sent to a suspended vibration classification screening machine for screening and classification, retaining 2-7mm particles;

[0036] (3) Drying and separation: The screened materials enter the tumble dryer, after being dried by an open flame, they are separated by an induced draft fan to extract light particles for use and remove heavy particles. The fan flow rate is 25000-35000m. 3 / h, speed 1000r / min, total pressure 1800~1300Pa;

Abstract

The invention relates to the field of agricultural biological recycling, and provides a novel method for preparing environmentally friendly biochar, making full use of a large number of dead navel orange trees in southern Jiangxi, and making biochar that meets international environmental protection requirements, and also has a unique fragrance, including raw material selection. , Mixing and screening, drying and separation, high-pressure molding, entering the kiln for carbonization, and smelting and exiting the kiln. The present invention uses a large amount of bamboo, sawdust, and the unique Chinese fir bark and navel orange tree dead in southern Jiangxi as raw materials, which are dried, pressed and carbonized. There are no chemical raw materials and additives in the production process, and the finished product has unique fir tree and The unique natural fragrance of navel orange meets international environmental protection requirements, providing high-end energy supply for the popular self-service barbecue.

Description

[0001] The invention relates to the field of agricultural biological recycling and utilization, in particular to a preparation method of biochar. Background technique [0002] With the growth of population and the development of productivity, the demand for energy of mankind is increasing, and it is urgent to find new energy. The state protects natural forests, and deforestable forests are declining. Only by making full use of waste regeneration, processing bamboo, wood chips and orange stems and other biological wastes from bamboo and wood processing into machine-made charcoal can reduce the waste of forest resources. [0003] Japan’s annual charcoal consumption is close to 90,000 tons, and its domestic production is about 15,000 tons. Southeast Asian countries supply about 20,000 tons. The remaining 50,000-60,000 tons are imported from China. The demand is very large, and with natural charcoal resources Still gradually decreasing. [0004] In southern Jiangxi, a large number of o...
