Abstract
The invention relates to a preparation system of biomass gas and biomass charcoal. The preparation system of the biomass gas and the biomass charcoal comprises a feeding unit, a pyrolytic reaction unit, a discharging unit and a pyrolytic reaction control system, wherein the three working units are successive, the pyrolytic reaction unit is provided with a pyrolytic reaction body, a screw propulsion device and an air supplying device are arranged in the pyrolytic reaction body, the pyrolytic reaction body is a rectangular cavity with a metal shell, and the pyrolytic reaction body cavity is vertically divided into two separable parts. Due to the arrangement of a heat insulation layer in the pyrolytic reaction body, the metal shell and a high-temperature reaction medium are effectively separated, and requirements for heat resistance of material of the pyrolytic reaction body cavity are reduced. Ordinary steel material can be adopted to reduce cost and effectively relieve temperature distortion of the metal shell, and therefore heat loss is reduced. Due to the fact that the pyrolytic reaction body is vertically divided into two parts, a bottom quick-wear part of the reaction body can be dismantled easily, and maintenance and replacement are convenient.
Description
Technical field
The present invention relates to the preparation system of a kind of biological fuel gas, biomass charcoal.
Background technology
The energy is the basis that modern society depends on for existence and development, and the supply capacity substantial connection of the energy the sustainable development of national economy, is one of basis of national strategy safety control.The situation is tense for the present energy resource supply of China, and the environmental quality burden is heavy.Due to the fossil energy reserves reduce day by day, oil price fluctuation is large, to the worry of energy security problem and to the concern of Global warming, the development clean reproducible energy has become urgent problem, the new forms of energy industry presents high development.According to industrial background and the general situation of development of the renewable energy source of extensive demonstration, the Biomass Gasification ﹠ Power Generation take biomass energy as representative, biomass hydrogen energy, biomass green liquid fuel will become following important substitute energy.Biomass energy belongs to clean energy, and the resource of the biological renewable energy of China is very abundant, and the extensive popularization and application of biological renewable energy helps to improve the ecological environment and CO2 reduces discharging.
Biomass refer to the various organisms that utilize atmosphere, water, soil etc. to produce by photosynthesis, and namely all the lived organic substances that can grow are commonly referred to as biomass.Biomass comprise all plants, microorganism and take plant, microorganism as the animal of food and the waste of production thereof.Representational biomass such as farm crop, agricultural waste material, timber, timber waste and animal excrement.According to statistics, approximately 1,460 hundred million tons of the annual yield of biomass in the world, wherein the yield of biomass in rural area every year just has 30,000,000,000 tons, is after the fossil energies such as oil, coal, Sweet natural gas, the current global the fourth-largest energy.Biomass are huge with its output, can store and the advantage such as carbon cycle has caused the extensive concern in the whole world.China's biomass resource is very abundant, and total resources is not less than 3,000,000,000 tons of dry-matter/years, is equivalent to 1,000,000,000 tons of oil equivalent/years, is about 3 times of the present consumption of petroleum amount of China.Wherein, often being only agricultural crop straw and agricultural byproducts etc. just has more than 700,000,000 ton, as feed, fertilizer and industrial raw material, approximately 60% can be used as energy use except 30%.(Zhu Xifeng, Lu Qiang. Fast Pyrolysis of Biomass for Producing Bio-oil [J]. scientific and technological Leader, 2007,25 (27): 69-75).The Main By product rice husk in the paddy course of processing for example, since two thousand five, the annual production of China's paddy continuous 4 years is more than 1.8 hundred million tons.Rice husk accounts for 20% of paddy usually, calculates like this, produces more than 3,600 ten thousand tons, rice husk per year, amounts to more than 1,800 ten thousand tons of standard coals, and visible China rice husk quantity is very huge.(Li Linna, Ying Hao, Sun Yunjuan etc. the progress [J] of China's rice husk recycling. biomass chemical engineering, 2010,44 (1): 34-38).
