Method for preparing carbon, gas, oil and solution in scale by thermally cracking biomass material

Abstract

The invention discloses a method for large-scale preparation of carbon, gas, oil and liquid by thermal cracking of biomass materials; the method includes the following production steps: material pulverization-drying and molding-thermal cracking-cooling and separation; in the invention, waste heat in a cooling system and a thermal cracking system is induced into a drying and molding system for drying materials, biomass fuel gas obtained by cooling and separation is burned to provide heat for thermal cracking, surplus biomass fuel gas is stored and used as industrial or domestic fuel. In thermal cracking, a plurality of thermal cracking reactors are taken as one batch to form one row which is positioned in a thermal cracking furnace. The method can raise comprehensive heat utilization efficiency of the system, greatly reduce unit energy consumption of products, improve the operating efficiency of the system, achieve outstanding energy-saving effect, shorten molding time of products, reduce heat emission and effectively control thermal pollution, thus achieving significant environmental production benefits. The method can realize large-scale production and has the capacity of treating tens of thousands of tons of raw materials every year.

Description

Technical field [0001] The invention relates to a method for preparing carbon, gas, oil, and liquid by using biomass thermal cracking technology. The preparation method can realize industrialized large-scale continuous production. Background technique [0002] As a problem in the world today, energy issues have attracted great attention from all countries. my country's per capita recoverable reserves of oil, coal, and natural gas are only 11%, 55%, and 4.3% of the world average; energy efficiency and unit product energy consumption are 40% higher than the world's advanced level, and the gap is obvious. How to realize the adjustment and optimization of the energy structure on the basis of improving energy efficiency has become the key to whether our country can achieve sustainable development. To this end, the state vigorously encourages the development of renewable energy and has formulated the "Renewable Energy Law" and a series of related policies to support it. Regarding bioma...

Problems solved by technology

The existing preparation methods mainly have the following two defects: 1. It is difficult to achieve large-scale production. On the one hand, it takes a long time from the crushing of biomass materials to the molding of products, especially the cooling time occupies most of the time of the entire production process. , making it difficult to scale production, and limiting the use and promotion of the system process

At the same time, due to the structural defects of the thermal cracking reactor, the increase of the overall output is restricted, and the raw materials that can be processed are only a few tons per day, so only small-scale production can be carried out; 2. The internal heat utilization efficiency of the system is low, which can only reach about 30%. , poor economic benefits, and weak market competitiveness; 3. While a large amount of heat energy is not fully and effectively recycled, it also brings serious thermal pollution, which has a bad impact on the health of operators and the surrounding environment
