Process for industrially producing carbon, gas, oil and electricity through biomass energy forming and destructive distillation

Abstract

The invention discloses a process for industrially producing carbon, gas, oil and electricity through biomass energy forming and destructive distillation. The process comprises the following steps of: raw material pretreatment: crushing raw materials; forming: pressing the crushed raw materials into formed particles in a certain shape; drying: controlling the moisture content in the formed particles at 3%-5%; destructive distillation: thermo-chemically converting the dried formed particles into granular carbon, gas and liquid under the condition of air isolation or in the presence of little air; acid washing: performing acid washing on the gas produced through the destructive distillation; cooling and separation: cooling the acid-washed gas and performing gas-liquid separation on the gas and the condensed liquid, and then performing wood tar-pyroligneous separation on the cooled liquid; and alkali washing: performing alkali washing on the cooled gas. The process is capable of converting the biomass raw materials into high-grade good-quality fuels and industrial raw materials.

Description

Technical field: [0001] The invention relates to the development field of biomass energy, in particular to the technology of biomass energy molding, pyrolysis and dry distillation industrial production of carbon, gas, oil and electricity. Background technique: [0002] At present, biomass energy is the energy stored in biomass, which is the energy stored in biomass by green plants converting solar energy into chemical energy through chlorophyll. Biomass energy has always been an important energy source for the survival of human society. It has dual characteristics of renewable and environmental friendliness. It has been widely valued by the world and has become one of the key development directions of new energy. It has the following characteristics: [0003] 1. Renewable and rich in resource stock [0004] Biomass energy resources are abundant. It is estimated that the annual energy stored in plants is about 10 times that of the world's main fuel consumption, and the amou...

Problems solved by technology

[0011] 5. High volatile content, easy to burn

[0014] 1. Biomass molding and pyrolysis dry distillation mostly use wood resources as raw materials. The limitation of wood resources and rising prices make this production fall into a predicament;

[0015] 2. The molding process of biomass molding and pyrolysis carbonization is mostly screw extrusion, which has high production energy consumption and short life of molding machine parts. The friction at the end of the screw rod makes the temperature rise and the wear speed is accelerated. There are 60-80h, the level of continuous production is low

[0016] 3. Biomas
