Problems solved by technology

However, the viscous nature of biomass pitch makes it difficult to be carbonized by uniform heating, and the solid charcoal particles produced during the carbonization process are mixed in the viscous biomass pitch and are difficult to separate, so that they are gradually enriched, which will lead to The viscosity of the bitumen further increases until the compaction solidifies in the carbonization equipment, forcing production to be interrupted

Abstract

The invention discloses a biodiesel residue treatment device which comprises a pyrolysis tank, a heating jacket and a rotatable scrape-coating mechanism arranged in the pyrolysis tank. The scrape-coating mechanism can receive a biomass asphalt raw material and uniformly scrape-coat the same on a heating wall to form a thin layer, the biomass asphalt raw material thin layer is heated and pyrolyzedon the heating wall to generate higher fat acid and higher fat acid pyrolysis gas, the pyrolysis gas is condensed into liquid from a pyrolysis tank top extraction portion by a vacuum device for the convenience of further treatment to be converted into biodiesel, pyrolysis residue is a carbonizing layer which is shoveled down from the heating wall by an arc-shaped plate at the front end of the scrape-coating mechanism and discharged from the bottom of the pyrolysis tank, and the pyrolysis residue can be converted into a high-quality activated carbon material after conventional treatment like activation.

Description

technical field [0001] The invention relates to a biodiesel residue treatment device. Specifically relates to a device for advanced treatment of biomass asphalt residue produced in the biodiesel preparation process to prepare biodiesel cracking products and activated carbon. Background technique [0002] Biodiesel has broad application prospects as a renewable alternative to fossil fuels. It is biodegradable, non-toxic, environmentally friendly, and has good lubricity; and compared with other fossil fuel substitutes, such as methanol, ethanol, etc., it has a higher unit calorific value and flash point, and it is easier to store, use, and transport. Safety. Therefore, among biofuel substitutes, biodiesel has received more attention, and its technology is more advanced and mature. [0003] The process of biodiesel preparation converts fatty acid glycerides into fatty acid methyl esters and glycerol by physical or chemical means. The fatty acid glycerides are derived from a...
