Embodiment

[0013] Embodiments The method for comprehensive utilization of energy from wood processing residues. The raw material is crop straw, which is processed into 5-25 mm long straw sections with a pulverizer. After that, the processed straw sections are put into a carbonization furnace, and controlled Carbonization temperature, time, and air supply, adjust the yield of gaseous products, liquid products and solid products, wherein the carbonization temperature is between 600 and 800°C, the carbonization time is 1 to 2 hours, and the equivalent ratio of oxygen supply (The volume fraction of the oxygen in the air and the oxygen required for the complete combustion of the fuel) is between 0.1 and 0.2. The gas phase products produced by carbonization are condensed to separate liquid substances (vinegar and tar) and gaseous substances (combustible gas). The gaseous substances can be used directly as fuel gas, and the liquid substances are separated by precipitation to separate water, tar ...

Abstract

The invention provides an energy regeneration comprehensive utilization method of lignification biomass materials such as crop straws, the processing residue of wood and bamboo, and logging slash in forest regions, which belongs to the wood science technical field, the method gives carbonization treatment to the raw materials, adjusts the yields of gaseous products (flammable gas), liquid products (vinegar liquid and tar oil) and solid products (biomass carbon) through the control of carbonization temperature, time, and supply amount of air, and energy regeneration comprehensive utilization is carried out to the materials for satisfying the requirements of different users. The method is characterized by the wide sources of raw materials, the low price, being easy to be got, the strong operability, and being safe and reliable, can better realize the energy regeneration comprehensive utilization of lignification biomass materials, and according to the requirements of users, the yields of gaseous products, liquid phase products and solid products can be adjusted.

Description

technical field [0001] The invention relates to a method for comprehensive utilization of lignified biomass materials as energy. The energy utilization of chemical materials belongs to the field of wood science and technology. technical background [0002] Lignified biomass raw materials are the fourth largest energy after coal, oil, and natural gas, accounting for 14% of the world's total energy consumption. In the world, with the rapid development of economy, the demand for energy is also increasing rapidly, resulting in a relative shortage of energy. Recently, the National Development and Reform Commission issued the "Eleventh Five-Year Plan" Guidelines for Comprehensive Utilization of Resources, emphasizing the need to focus on the development of agricultural waste, "three leftovers" of forest trees, and secondary small fuelwood and other lignified biomass resource utilization issues. [0003] my country is a large agricultural country with abundant straw resources. Ri...
