Embodiment

[0035]Put the prepared biomass on an electronic balance to weigh and record the value, weigh three parts and put them into the third layer, the second layer, and the first layer of the feeding storage device 1 in sequence. Connect the instrument and equipment to the nitrogen cylinder, connect the instrument plug, turn on the main power of the pyrolysis device, blow nitrogen gas (flow rate 150ml / min) through the pipeline, check the air tightness of the device, ensure that no other gas enters, and continue to purge the nitrogen gas 5min, remove the oxygen in the pyrolysis chamber, create a nitrogen environment pyrolysis chamber 4, make the pyrolysis chamber 4 reach an oxygen-free or anoxic environment, set the fixed bed pyrolysis reaction temperature to 450°C, turn on the power of the instrument, and use the thermoelectric With the heating of the couple, the temperature in the pyrolysis chamber 4 increases gradually. When the temperature rises to the preset pyrolysis chamber 4 t...

Abstract

An oil producing device integrating biomass drying, crushing and pyrolysis is provided. The device includes a fed material storage device, a furnace chamber, a pyrolysis chamber, a crusher, a condenser and a ventilation pipeline. The pyrolysis chamber is disposed in the furnace chamber. A feeding device is disposed on the pyrolysis chamber. The crusher is disposed in the pyrolysis chamber. The inlet of the condenser is connected to the outlet of the pyrolysis chamber, and the outlet of the condenser is connected to the ventilation pipeline. After a raw material is fed into the pyrolysis chamber, the raw material is crushed and stirred by the crusher in the pyrolysis chamber, and a thermocouple in the pyrolysis chamber adjusts the temperature in the pyrolysis chamber through a temperature controller. A pyrolysis product is fed into the condenser from the outlet of the pyrolysis chamber through a pipeline, biological oil after condensation is collected and residual carbon is collected atthe bottom of the pyrolysis chamber. Gas that cannot be condensed is conveyed to the fed material storage device through the ventilation pipeline, and waste heat of the gas is utilized to dry the biomass in the fed material storage device. The oil producing device is beneficial to sufficient biomass pyrolysis, and increases the yield of the biological oil by about 15%, heat can be recycled and air pollution is reduced.

Description

technical field [0001] The invention relates to the field of biomass energy recovery and utilization, in particular to a pyrolysis oil production device with high yield, high efficiency and energy recycling using biomass as a raw material. Background technique [0002] Fossil energy is non-renewable energy, and the use of fossil energy has produced serious pollution, so the development of new clean energy has become a research hotspot today. Biomass is renewable, widely distributed, and has large reserves. From the perspective of carbon life cycle, biomass pollution is very low. Bio-oil produced by pyrolysis of biomass is a renewable and clean energy, which has become a research hotspot in the field of energy. [0003] Biomass pyrolysis technology is a process in which biomass is decomposed into solid residual carbon, liquid bio-oil and combustible gas by providing a moderate pyrolysis temperature under anaerobic conditions or a small amount of oxygen supply. Among them, t...
