New carbonization furnace for biochar production

Abstract

The invention provides a novel carbonization furnace for producing charcoal. A combustor is arranged in a furnace body, a furnace cover is arranged in the upper part of the furnace body, a charging opening is formed in the top of the furnace cover, a top cover is arranged at the charging opening, a smoke outlet is formed on a bottom plate of the furnace body and is communicated with a smoke treatment device through a smoke outlet pipeline, an air inlet is formed in the lower part of the furnace body, the air inlet is connected with an air blower through a pipeline, a furnace door is arranged in the middle part of the furnace body, the furnace door is moveably connected with the furnace body, and a lower sealing gasket is arranged between the furnace door and the furnace body. According to the novel carbonization furnace provided by the invention, the furnace door is arranged on the furnace body of the carbonization furnace. An operator enters into the carbonization furnace from the furnace door. After a combuster is ignited, the operator rapidly exits from the furnace door without a wall-climbing operation. The height of the furnace body is no longer limited, and the furnace body can be easily made big enough, so that the carbonizing production capacity is improved and the production efficiency is improved, and moreover, the smoke outlet of the carbonization furnace is communicated with tail gas treatment equipment, and air discharged by the carbonization furnace is purified and discharged again, so that the environment is prevented from being polluted.

Description

[0001] Technical field: [0002] The technical field of mechanical equipment for biochar production of the present invention specifically relates to a novel carbonization furnace for biochar production. [0003] Background technique: [0004] Biochar is a solid product produced by low-temperature thermal cracking of biological organic materials (biomass) in anoxic or anaerobic environment. Biochar can be used as a high-quality energy, soil amendment, as a reducing agent, fertilizer slow-release carrier and carbon dioxide sequestration agent. It has been widely used in carbon sequestration and emission reduction, water purification, heavy metal adsorption and soil improvement, etc. To a certain extent, it provides solutions to hot issues of global concern such as climate change, environmental pollution and soil function degradation. [0005] The biomass used in the production of biochar comes from a wide range of sources. In our country, a large amount of agricultural and forestry wast...

AI Technical Summary

Problems solved by technology

This kind of carbonization furnace, because the burner is located in the furnace body, and the surroundings of the furnace body are closed, after manually igniting the burner, the operator needs to turn over the wall from the furnace body, which leads to the height of the furnace body not being too high and the volume of the furnace body not being too large , the production capacity of the carbonization furnace is limited, and the production efficiency is relatively low. At the same time, the biomass particles made of dry agricultural and forestry wastes are flammable. Manually igniting the burner in the furnace is relatively dangerous, and it is easy to cause casualties
