Comprehensive application technique for biomass pyrolysis carbon gas

Abstract

The invention relates to a comprehensive application technique for a biomass pyrolysis carbon gas. In the comprehensive application technique, smash forming equipment (1), a pretreatment device (2), a high-temperature pyrolysis device (3), a gas-liquid separation system (4), a gas purification system (5), high-pure flammable gas (6), original carbon (7), activated carbon (8), liquid collection (9) and liquid deep processing (10) are mainly utilized. Straw or sawdust and the like are processed into required shape and size by using the smash forming equipment (1); the formed material is processed through the pretreatment device (2) so as to improve the characteristic of the material; the treated material is fed to a high-temperature pyrolysis device (3) so as to be heated, and the biomasses such as straw or sawdust and the like are decomposed into carbon and gas at a certain temperature within a certain period of time, wherein the gas parts are separated into liquid and gas by the gas-liquid separation system (4); the gas is fed to the gas purification system (5) for purification, and high-pure hydrogen and carbon monoxide after purification are stored in a gas storage device (6); the original carbon enters into a collection device (7), is processed into the activated carbon through an activated device (8); and the liquid parts enter into a liquid collection device (9) and are extracted and classified through a liquid deep processing system (10), and products such as biopesticide and the like are processed by adding auxiliaries according to requirements. Continuous industrial production is carried out in the whole process and automatically controlled; and required operators are less, and the energy consumption is low. More than 10 steres of biomass to be pyrolyzed is achieved each day, and at least 2000 steres of flammable gas and 3 steres of activated carbon as well as other products are produced.

Description

technical field [0001] The invention relates to high-temperature decomposition of straw, sawdust and other biomass into active carbon, high-purity combustible gas (hydrogen, carbon monoxide), biological pesticide and other substances. To achieve the purpose of environmental protection and produce higher value-added products. Background technique [0002] A large amount of biomass straw and bamboo and wood waste are produced in my country every year, which are basically burned and discarded, causing environmental pollution and waste of resources. Although there have been a small number of engineering applications of biomass gasification technology in recent years, most of them produce combustible gas and charcoal for heating. The technology is backward, the efficiency is low, and the added value of the product is low. The invention can realize continuous and uninterrupted production, has high degree of automation, low energy consumption, high added value of products and zero...
