Seaweed Biomass Rotary Kiln Dry Distillation Oil Production System

Abstract

The invention discloses a seaweed biomass carbonization oil-making system of a rotary kiln in the technical field of biological carbonization. In the seaweed biomass carbonization oil-making system, an input end of a circulating fluidized bed combustion furnace is respectively connected with a starting fuel feeding device, a combustion furnace bed material feeder, an output end of a carbonization furnace return feeder and an output end of a combustion furnace return feeder; an output end of the circulating fluidized bed combustion furnace is connected with a combustion furnace cyclone separator; a first output end of the combustion furnace cyclone separator is respectively connected with a dust remover and a steam turbine. The seaweed biomass carbonization oil-making system can implement carbonization heat self-supply balance when the seaweed is used to carbonize and make oil, become an energy self-balance system for seaweed biomass carbonization oil-making, overcome the defect of poor combustion effect in a small space of a small boiler, and improve the combustion efficiency. The seaweed biomass carbonization oil-making system is good in low-load stable combustion and high in the burn-off rate.

Description

technical field [0001] The invention relates to a system used in the dry distillation technical field of a specific solid raw material or a special form of solid raw material, in particular to a dry distillation oil production system of a seaweed biomass rotary kiln. Background technique [0002] Nowadays, people are increasingly facing the severe challenge of lack of energy resources. Global oil demand will grow at an annual rate of 1.9%. In 2025, the average daily global oil demand will rise from 77 million barrels in 2001 to 121 million barrels, of which the growth in the United States and developing Asian countries will account for about 60%. US Department of Energy Energy Information Administration. International Energy Outlook 2004, Tsinghua University Press, 2004. According to the 2003 statistics of the Oil and Gas Journal of the United States, the remaining recoverable oil reserves in the world are 156.7 billion tons, or about 1,148.6 billion barrels. According to t...
