Embodiment

[0052] The implementation of this example is as follows. The test scale is 500kg / h (500kg of material throughput per hour, 1-2 tons of material oil per day).

[0053] (1) Drying: In order to avoid excessive moisture in the material being brought into the bio-oil, the material must be dried. This embodiment uses a 7.5KW Shandi brand dryer with a motor power of 700kg per hour. . The moisture content of the dried material is required to be no more than 8%.

[0054] (2) Crushing: In order to increase the yield of biomass oil, the material needs to be pulverized. This is necessary to increase the heating rate. Because the particle size of the material is small enough to ensure a high heating rate is one of the important conditions. In this embodiment, rice husk is used as material; its particle size is 1-1.5 mm.

[0055] (3) Feeding. Conveying materials is one of the important technical links in the pyrolysis process. Because biomass pyrolysis is the biomass (material) under...

Abstract

The invention discloses an oil making method through rapid heat cracking, which comprises the following steps: drying and grinding the raw materials; transmitting the disposed materials into rector to crack; separating the product to obtain the biological oil.

Description

technical field [0001] The invention relates to a method for preparing biomass oil, in particular to a method for processing 500 kilograms of rice husk powder per hour by using rapid pyrolysis technology to produce one ton of biomass oil per day. Background technique [0002] Energy is one of the important material foundations for the existence and development of human society. Over the past 200 years, energy has mainly relied on energy systems based on coal, oil, and natural gas. However, the depletion of these resources and the continuous deterioration of the environment have brought serious consequences to the earth and threatened the survival and development of human beings. Entering the 21st century, energy issues related to national security and sustainable economic and social development have become the central issues facing all countries in the world today. [0003] As the fourth largest energy resource in the world's primary energy consumption, biomass energy has ...
