Equipment for producing biochar from rice straw and technology for producing biochar

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 b
