Problems solved by technology

However, due to the low heat conduction efficiency of biomass, the reaction time is long, the energy consumption of pyrolysis is increased, and the material near the center of the reactor cannot be effectively heated and there is often a phenomenon of sandwiching, and the product quality is not easy to guarantee.
In addition, due to the high temperature of the newly generated biochar, it cannot be directly removed and collected. Natural cooling is often used in production, so a very long cooling residence time is required. Some technologies use the form of adding circulating water to the outer layer of the carbon auger. Cooling, but due to the low thermal conductivity of biochar, the overall cooling effect is very poor, seriously affecting production efficiency

Abstract

The invention discloses a multi-channel high-efficiency pyrolysis device comprising five parts: a feed system, a pyrolysis system, a heat insulation system, a cooling system and a carbon discharging system. The device makes full use of a high-efficiency biomass pyrolysis way of a multi-channel pyrolysis reaction channel and a multi-channel cooling way, and a high-efficiency production way having high-efficiency pyrolysis and rapid cooling carried out simultaneously is formed; the device is beneficial to high-efficiency thermal conductivity and rapid cooling of biomass, increases the pyrolysis efficiency, facilitates carbon collection, reduces energy consumption, and improves the production efficiency.

Description

technical field [0001] The invention relates to a multi-channel simultaneous reaction high-efficiency heat conduction device, which is suitable for biomass pyrolysis reaction, in particular to a multi-channel high-efficiency pyrolysis device. Background technique [0002] Biomass pyrolysis refers to the process in which biomass is heated to cause molecular cracking to generate biochar, condensable liquid and combustible gas in an oxygen-free or low-oxygen environment. Biochar is widely used in metallurgy, chemical industry, national defense, agriculture, and environmental protection; condensable liquids include wood vinegar and wood tar, and wood vinegar is a natural plant growth regulator, which has the functions of promoting plant growth, sterilizing, and preventing insects. , anti-corrosion, deodorization, improvement of soil environment and other functions; wood tar is a high-quality chemical raw material for the production of waterproof and anti-corrosion, and is mainly...
