Biomass continuous pyrolysis control system and biomass continuous pyrolysis control method

Abstract

The present invention relates to a biomass continuous pyrolysis control system and a biomass continuous pyrolysis control method. The system comprises hoppers, a continuous pyrolysis reactor and charcoal boxes which are connected orderly, a first-grade condenser communicated with the continuous pyrolysis reactor and the charcoal box simultaneously, a second-grade condenser communicated with the first-grade condenser, and an air storage tank connected with the second-grade condenser and communicated with the continuous pyrolysis reactor. The hoppers comprise a first-grade hopper and a second-grade hopper in which the distance sensors are arranged respectively, a feeding port of the first-grade hopper is equipped with a first valve, and a second valve is arranged at the communication position of the second-grade hopper and the first-grade hopper. The charcoal boxes comprise a first-grade charcoal box and a second-grade charcoal box in which the distance sensors are arranged respectively, the first-grade condenser is communicated with the first-grade charcoal box, and a third valve is arranged at the communication position of the first-grade charcoal box and the second-grade charcoal box. A fourth valve is arranged at a discharging port of the second-grade charcoal box, the distance sensors are all connected with a controller, and the first to fourth valves are all connected with the controller. According to the present invention, the accurate control of feeding and discharging is realized.

Description

technical field [0001] The invention relates to the field of biomass energy utilization, and more specifically, to a biomass continuous pyrolysis control system and method. 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 extensive use of fossil fuels has caused serious pollution to the environment. The problem of energy shortage and environmental deterioration has become a hot topic in the society. Biomass energy is the fourth largest energy source after fossil energy such as coal, oil, and natural gas. It is currently the main supplementary fossil fuel resource in the world. It has the advantages of stable source, huge output, renewable, storable, and carbon cycle. And biomass is the only renewable energy that can be converted into gas, liquid, and solid energy forms, so it has received extensive attention from all over the world. [0003]...
