Problems solved by technology

However, the current preparation of straw biochar is generally carried out in a furnace. This method is not suitable for large-scale production and use of biochar due to uneven heating temperature control and uneven carbonization of straw, resulting in insufficient uniformity of biochar after preparation.

Abstract

The invention discloses a device for preparing biochar by means of straw. The device for preparing the biochar by means of the straw can greatly improve the biochar preparation efficiency and the automation degree, a rotatable ceramic carbonization disk is adopted for carbonization, not only can accurate control of a carbonization temperature be ensured, but also automatic loading and unloading can be achieved, the labor intensity of a labor is reduced, meanwhile, to-be-carbonized straw blank bars are placed in the ceramic carbonization disk in a radical direction, not only can occupied spacebe reduced, but also the condition that each straw blank can be subjected to carbonization accurately and evenly is ensured, the carbonization effect is excellent, the carbonization performance is ensured, and in a carbonization process, accurate temperature monitoring and control can be conducted, so that the carbonization effect is ensured.

Description

technical field [0001] The invention relates to a device for preparing biochar by utilizing straw, and belongs to the technical field of straw carbonization equipment. Background technique [0002] Biochar refers to the high-temperature treatment of biomass under anoxic conditions, the oil and gas in the biomass are burned, and the rest is biochar. Biochar is almost pure carbon, and it will not disappear for hundreds to thousands of years after being buried in the ground. It is equivalent to sequestering carbon into the soil and helping to slow down global warming. It has aroused widespread interest in biochar all over the world. Many scientists believe that using biochar to capture carbon is quite stable, it can "lock" carbon in the ground for hundreds of years, and make the soil more fertile; in addition, it can also reduce the emission of greenhouse gases such as nitrogen dioxide and methane . [0003] Currently, the modern method of making biochar is to heat plant wast...
