Production method of straw carbon

Abstract

The invention discloses a production method of straw carbon. The straw carbon is obtained by performing compression forming on combustible plants such as straws and continuously carbonizing the straws in a carbonizing furnace. The method comprises the following steps: compressing raw materials, putting the compressed raw materials into a circulating feeding device, feeding the raw materials into the carbonizing furnace, adjusting the temperature in the carbonizing furnace, discharging water and tar from the raw materials and gas such as CO generated in a production process, adjusting the temperature in the carbonizing furnace to be 650 DEG C, at the moment, and performing dry distillation on the raw materials at the high temperature to form the carbon; discharging a finished product from the furnace and cooling for later use. According to the method, the circulating feeding device serves as a carrier for feeding the raw materials into the furnace and a carrier for discharging the finished product from the furnace, is capable of feeding the raw materials into the furnace while discharging the finished product, and is cyclically used to ensure the continuous production; a gas decomposition device is capable of decomposing water, steam, combustible gas and the like generated in the carbonizing process of the raw material from the raw materials, and the substances generated in the carbonizing process are discharged from the carbonizing furnace in a heated vaporization manner; the problems of low carbon density and heat value and high rejection rate and cost of an existing product are solved.

Description

technical field [0001] A method for producing straw charcoal, specifically relating to a method of dehydrating and gasifying plant stalks, stems and leaves such as crop stalks, leaves, husks, rice husks and weeds as raw materials to convert them into charcoal production method. Background technique [0002] Today's rural areas have implemented a family-based joint production contract responsibility system, and with the acceleration of agricultural mechanization, cattle, horses, donkeys, and mules are no longer raised as livestock power, and straw is no longer used as feed and becomes abandoned; as farmers With the improvement of living standards, gas, electricity, and coal have entered thousands of households as energy sources. A large number of plant stalks, stems, and leaves such as straw, leaves, husks, chaff, and weeds have been discarded or even rotted, becoming a source of pollution in rural areas. Some farmers A large amount of straw is burned, which seriously pollut...

Problems solved by technology

The disadvantage is that the operation is complicated and the carbonization effect is not good.

[0005] The traditional straw carbonization method has high production costs, and its production equipment wears out quickly, which is prone to excessive carbonization or insufficient carbonization, and its products have low carbon density, low calorific value, high defective rate, and high production costs.
