Internal-heating continuous type biochar equipment

Abstract

The invention discloses a set of internal-heating continuous type biochar equipment and belongs to the technical field of renewable energy sources. According to the technical scheme, the set of internal-heating continuous type biochar equipment comprises a feeding hopper (2), a continuous carbonizing furnace (7), an operating platform (17) and a three-way discharge port (13); the middle part of the operating platform (17) is fixedly connected with the carbonizing equipment main body (7), the upper part of the operating platform (17) is in slide connection with a crane (18), a material active compactor (6) is arranged at the top part of the operating platform (17), and detecting probing holes (9) are uniformly distributed around the lower part of the operating platform (7); and the upper part of the three-way discharge port (13) is rotatably connected with a perturbator (19) in the continuous carbonizing furnace (7). According to the set of internal-heating continuous type biochar equipment, the raw material is fed into the carbonizing furnace body through the feeding hopper, the temperature in the furnace body is raised, the pyrolytic reaction is carried out, and the produced biochar is conveyed down out of the furnace body. By adopting the set of internal-heating continuous type biochar equipment, the problems that the raw materials cannot be fed continuously and full carbonizing cannot be realized in the production of biochar can be solved, and the productivity is improved; and the set of internal-heating continuous type biochar equipment is suitable for different biomass materials. The set of internal-heating continuous type biochar equipment provides guarantee for promoting the development of the biochar industry in China.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and in particular relates to a complete set of internal heating continuous biochar equipment, in particular to the equipment for producing biochar by means of pyrolysis using crop straws as raw materials. Background technique [0002] my country's annual output of straw is about 700 million tons, about 50% of these straws are used as firewood, and about 16% are burned in the open air, causing serious environmental pollution, and there are still more than 4 billion tons of organic waste every year. The output of garbage has an impact on the environment. In the context of global energy conservation and emission reduction, my country has also proposed a rigid target of reducing carbon dioxide emissions by 40-45% compared with 2005 by 2020. Therefore, rational disposal of these biomass wastes is one of the urgent problems to be solved. The thermal cracking process of agricultural biomass bas...
