Continuous external-heating vertical type biomass pyrolysis carbonization apparatus

Abstract

A disclosed continuous external-heating vertical type biomass pyrolysis carbonization apparatus comprises a charging system, a pyrolysis carbonization reactor, a biological carbon discharging system, a purification system and the like. By employing a two-grade charging structure and a two-grade discharging structure which are cooperated with raw material self gravity for playing a role, the seal of the apparatus is guaranteed, and the continuity of the pyrolysis carbonization reaction is realized; by employing a speed-adjustable two-grade spiral charging conveyor and a spiral discharging conveyor, the raw material movement speed and the reaction detention time can be accurately controlled, and thus the quality stability and controllability of biological carbon are guaranteed; and the pyrolysis carbonization reactor comprises four temperature zones capable of independently controlling the temperature, the reactor can be set to be heated successively from top to bottom according to different needed temperature at each stage of the pyrolysis reaction, so that the needless high temperature at the initial stage of the pyrolysis reaction is avoided, and energy is effectively saved. The apparatus provided by the invention is simple in integral structure and easy to realize, the main product is biological carbon, the yield is high and the quality is stable.

Description

Technical field: [0001] The present invention relates to a continuous external heating vertical biomass pyrolysis carbonization device, in particular to a continuous external heating vertical biomass pyrolysis carbonization device whose main purpose is to obtain biochar products and which is sealed by a secondary feeding and secondary discharging structure. Biomass pyrolysis carbonization device. Background technique: [0002] With the rapid growth of the world's population and the development of economy and technology, people's demand for energy has increased sharply, and the impact of climate change and other effects brought about by the use of fossil fuels has also aroused widespread concern. In order to solve the above problems, the global interest in the field of renewable energy has been growing in recent years. Biomass is considered to be the world's main renewable and clean energy that supplements fossil fuel resources and improves the ecological environment, and is...
