Embodiment 1

[0020] Corn stalks and sorghum stalks are used as main raw materials. After being chopped according to the above process, the dust and waste materials that do not meet the requirements for carbonization materials are screened and removed. After drying and dehydration, the moisture content is controlled at 15%. 4 meters, 2 meters in width, and 3 meters in the above-mentioned furnace carbonization chamber 8, add the undersieve straw fines and other agricultural and forestry wastes that are not suitable for carbonization materials into the gasification chamber 7 in the furnace to ignite , start the blower to blow air (gasification agent) into the air inlet pipe 14 at the bottom of the gasification furnace chamber, so that the gasification material added to the gasification furnace chamber 7 undergoes gasification reaction to generate a high-temperature combustible gas at 500-700 ° C. Under the action of the suction fan outside the furnace, the high-temperature combustible gas is s...

Embodiment 2

[0023] With branches and cotton stalks as the main raw materials, after being chopped according to the above process, the dust and waste materials that do not meet the requirements for carbonization materials are screened and removed, and then after drying and dehydration, the moisture content is controlled at 15%, and then long In the carbonization furnace cavity 8 in the above-mentioned furnace with a width of 6 meters, a width of 3 meters, and a height of 4 meters, the above-mentioned undersieve cotton stalk fines and other agricultural and forestry wastes that do not meet the carbonization materials are added to the gasification furnace cavity 7 in the furnace Ignition, start the blower to blow air (gasification agent) into the air inlet pipe 14 at the bottom of the gasification furnace chamber, so that the gasification material added to the gasification furnace chamber 7 undergoes gasification reaction to generate high-temperature combustible gas at 500-700 °C , under the ...

Abstract

The invention includes a method to produce biological carbon and its double-furnate charring furnace. The method is: shatter, filter, dry and place the materials meeting the requirements in to cavity of charring furnace separately, ignite the material in cavity of gasification furnace to make gasification, putout the biological carbon dry distilled and charred in the cavity of charring furnace through the outlet for product. The main structure of double-farnace charring furnace includes there are mouth of pipe in the middle of upper furnace, and cavity of gasification furnace and cavity of charring furnace in the furnace. Its has biological fuel gas with hest value of 800-1000kg / m3, can be reused, after being scatter and add into watersoluble high molecular sticker, is useful to prolong the time of exhaustion of delay the fossil fuel resure; it makes good use of waste in farming and forestry, saves energy, has simple and reasonable structure of double-furnace charring furnace, convenient operation and large quality of processing material, high speed and efficiency of caring in furnace.

Description

Technical field: [0001] The invention relates to a method for producing biomass charcoal in a gasification furnace cavity and a carbonization furnace cavity separately arranged in the same furnace from agricultural and forestry wastes such as biomass stalks, tree branches and fruit shells. Specifically, after the above-mentioned materials are sliced, chopped or pulverized, and dried, they are added to the gasification furnace chamber and carbonization furnace chamber separately arranged in the furnace. The material undergoes gasification reaction to produce high-temperature combustible gas, and then the generated high-temperature combustible gas is sucked into the carbonization furnace cavity of the furnace to carbonize the material in the carbonization furnace cavity to produce biochar. Background technique: [0002] The composite carbonization furnace in the prior art has a utility model patent number: ZL03221637.8. Its production method is to crush and dry agricultural an...
