Embodiment 1

[0087] Set relevant parameters: feed rate 10ml / min, reactor volume 100ml, feeding volume 50ml, 11 reactors (numbered 1-11 reactors according to feeding order), reaction temperature 300°C, heating rate 15 ℃ / min, reaction time 30min;

[0088] System action execution process: Livestock and poultry manure is used as the raw material, and the material is fed by the feeding system. First, the No. 1 reactor is controlled to feed 50ml, and it is heated for 20 minutes to reach the reaction temperature of 300°C. At this time, 4 reactions of No. 2-5 The kettle was filled with material (50ml). The reaction time is 30min, and the time period is full of No. 6-No. 11 reactors. When the reaction time is reached, the second valve device 17 below the No. 1 reactor is opened to discharge the material. After the discharge is completed, the second valve device 17 is closed. And open the first valve device 16, No. 1 reactor feed, open the second valve device 17 when No. 2 reactor reaches reaction ...

Embodiment 2

[0090] Set relevant parameters: feed rate 20ml / min, reactor volume 200ml, feed volume half of reaction volume 100ml, 8 reactors, reaction temperature 280°C, heating rate 20°C / min, reaction time 20min;

[0091] System action execution process: Fiber materials such as corn stalks are used as raw materials, and the materials are fed by the feeding system. First, 100ml is fed into the No. 1 reactor, and it is heated for 14 minutes to reach a reaction temperature of 280°C. At this time, No. 2 and No. 3 2 reactors have been filled with material (100ml), and reactor No. 4 is 4 / 5 full (80ml). The reaction time is 20min. During this time period, the 4 reactors numbered 4-7 and the reactor No. 8 are full of 4 / 5 (80ml), and the reactor No. 8 continues to feed. When the reaction time is reached, the reactor No. 1 reacts The second valve device 17 below the kettle is opened automatically and carries out discharging, and after discharging finishes, the second valve device 17 closes and open...

Description

technical field [0001] The invention relates to the technical field of bio-crude oil preparation, in particular to a device and method for continuously preparing bio-crude oil. Background technique [0002] Biomass hydrothermal liquefaction (Hydrothermal liquefaction) uses biomass such as microalgae, crop straw, tree branches and leaves, livestock and poultry manure, and kitchen waste as raw materials, and uses water as the reaction solvent. A technology that rapidly converts biomass into bio-crude oil under temperature and pressure. Bio-crude oil is a mixture of complex organic components with extremely high carbon content and properties similar to crude oil produced by hydrothermal liquefaction of biomass. Hydrothermal liquefaction technology prepares bio-crude raw materials without drying, and can directly undergo hydrothermal reaction to avoid drying energy consumption. In addition, the latent heat loss caused by the phase change process of water evaporation can be avo...
