Problems solved by technology

There are already methods for carbonizing raw materials such as branches and straws to prepare biochar, but most of them have low carbonization rates, usually no more than 80%, and the biochar produced has poor parameters such as specific surface area and porosity. The problem of uneven quality limits the reuse of branches and straw

Embodiment 1

[0030] A method for reusing willow waste and old branches, comprising the steps of:

[0031] (1) Branch pretreatment:

[0032] a. Put the waste branches collected by willow weaving or weaving into categories according to specifications, and then rinse them repeatedly with clean water to remove sand, mud and other impurities on the surface for later use;

[0033] b. Put the waste and old branches treated in operation a into a press, squeeze out the moisture inside the waste and old branches with external force, and perform shape correction on them, then take out the waste and old branches for later use;

[0034] (2) Surface coating removal treatment:

[0035] Put the waste branches treated in step (1) into the coating removal solution, heat to keep the temperature of the coating removal solution at 33~34°C, then take it out after soaking in heat for 15 minutes, and then rinse the waste branches with deionized water under high pressure Surface, after finally draining the surfa...

Abstract

The invention discloses a waste willow artwork branch recycling method. The waste willow artwork branch recycling method comprises the following steps: (1) preprocessing the branch; (2) removing a surface coating; (3) processing at high temperature and high pressure; (4) processing by using an acid-base solution; (5) modifying; (6) carbonizing. The waste willow artwork branch material is processed in a targeted manner, the surface and the inner organizational structure of the branch are changed, the content and the proportion of the internal substance are regulated, the process parameters in the carbonizing are controlled, so that the overall carbonation ratio is effectively improved, the carbonation quality is improved, the carbonation ratio of the branch is finally more than 99.5%, the specific surface area of the prepared bio-carbon is not less than 3500 m<2> / g and increased by more than 20% in comparison with the prior art, the proportion of micropores in the prepared bio-carbon is more than 96.5%, a quite excellent adsorption characteristic is shown, and the use value is very high.

Description

technical field [0001] The invention belongs to the technical field of straw material processing technology, and in particular relates to a method for reusing waste wicker branches. Background technique [0002] Funan County, affiliated to Fuyang City, Anhui Province, is an early inland development area, located in the northwest of Anhui Province, on the north bank of the junction of the upper and middle reaches of the Huaihe River. Funan County is known as "Famous Specialty Products County" and "Natural Resource Bank". It is a major grain production county in the country, the hometown of willow weaving in China, and the only agricultural (forestry) circular economy demonstration pilot county in the country. Funan is the national willow weaving county. Township, willow products are sold abroad. [0003] Willow products are common containers and handicrafts in people's daily life, but like most commodities, they have a certain service life. After the structure is damaged, th...
