Abstract

The invention discloses equipment for producing biochar from rice straw. The equipment comprises a feeding box, a pulverizator, a reaction vessel, a discharge delivery pipe, a pyrolysis box, a heating stove, a first cooler and a second cooler. Meanwhile, the invention discloses a technology for producing the biochar. The method comprises steps as follows: firstly, the rice straw enters the feeding box through a feed inlet and then enters the pulverizator for pulverization; the pulverized rice straw enters the reaction vessel through a discharge valve and is processed, the processed rice straw is cooled by the first cooler, is sent to the pyrolysis box through the discharge delivery pipe for high-temperature pyrolysis and then is conveyed to the heating stove for carbonization, and the carbonized rice straw is discharged from a discharge port after cooled by the second cooler. The production technology is simple, the energy consumption of the equipment is low, and the cost is lower than that of other methods by 8% or more; the production cycle is short, the controllability of a production process is high, and apparent specific gravity of the obtained biochar is high.

Description

technical field [0001] The invention belongs to the technical field of biochar production equipment and technology, and relates to rice straw biochar production equipment and a process for producing biochar. Background technique [0002] With the increase of crop production year by year, the development of rural urbanization and the further improvement of farmers' living standards, the output of crop straw has increased significantly. At the same time, the proportion of straw used as firewood has gradually declined, and a large amount of surplus straw has been abandoned on the fields and roadsides. Or ditches, or burning at the head of the field, has brought great hidden dangers to the ecological environment and the safety of life and property. my country is a major rice producing country, and a large amount of rice straw is produced every year. Rice straw is a by-product obtained after rice threshing and seed harvesting. The threshing stem and attached dry leaves become str...
