Abstract

The invention discloses a device and a method for producing biological fuel oil by quickly cracking biomass, relates to a device and a method for producing biological fuel oil and aims to solve the problems of low energy utilization ratio, high operating cost and poor practical production continuity existing in the conventional biomass thermal cracking process and the problem of the absence of accurate heat carrier heating temperature regulating function in the conventional biomass thermal cracking process device. In the scheme of the device, the bottom of a heat carrier heating device is communicated with a heat carrier inlet end of a cracking reactor through an accurate heat carrier temperature control device; the cracking reactor is communicated with a separator; the separator is communicated with a condenser; the condenser is communicated with a heat energy supply device; and the heat energy supply device is communicated with the heat carrier heating device. In the scheme of the method, products produced by the thermal cracking reaction of biomass powder comprise thermal cracking gas and carbon; a heat carrier enters a heat carrier collecting box; and uncondensed thermal cracking gas enters a non-condensable gas burner to burn, and then smoke gas is produced and enters the heat carrier heating device. The device and the method are used for producing biological fuel oil.

Description

technical field [0001] The invention relates to a device and method for producing biofuel. Background technique [0002] Bio-oil produced from biomass is a new type of liquid energy that is extremely versatile and can replace petroleum to a certain extent, and is renewable. It can be directly used as fuel instead of petroleum to a certain extent, and it can also be mixed and emulsified with gasoline and diesel in a certain proportion to make a clean and environmentally friendly "bio-fuel + diesel" mixed emulsified fuel. Experiments have shown that this fuel can Used on ordinary diesel engines, it not only saves oil, but also reduces greenhouse gas emissions caused by burning oil in large quantities. [0003] Biomass pyrolysis refers to the rapid heating of biomass to pyrolyze biomass in the absence of oxygen or anoxic conditions to produce pyrolysis gas and charcoal, and rapid cooling of pyrolysis gas to convert condensable components into liquid biofuels the process of. ...
