Description
Technical field
The present invention relates to a kind of gas cleaning separating device, specifically a kind of taking agricultural crop straw the Multifunctional separation equipment for high-temperature biological mixed gas in main biomass waste resource pyrolysis gasification system.
Background technology
China is a large agricultural country, has produced the biomass waste resource such as a large amount of agricultural crop straws, chaff slag in agriculture production and processing of farm products.Traditional utilizes mode mainly as home energy source, feed, fertilizer, industrial raw material and material of construction.Along with the fast development of agrotechnique modernization and rural economy, life in the countryside level significantly improves and the sudden change of the mode of production of living, rural households select the ratio of commercial energy resource improving constantly, agricultural crop straw is constantly declined as the quantity of the energy, and commercial energy resource (as coal, liquefied gas etc.) has become main cooking energy.Cultivation institute is in order to biomass straw, and weeds feed is substituted by commercial feed, and the required biomass organic fertilizer of agriculture production is substituted by inorganic fertilizer, and life of farmers and agriculture production stalk used sharply declines.Meanwhile, agricultural crop straw output is with farm crop, particularly the increase of food crop output and increasing rapidly.Drug on the market causes that stalk is abandoned in field, house courtyard for agricultural crop straw, even directly burned in field.Abandon and can affect environment and initiation fire at the stalk in house courtyard and field, cause pollution of waterhead.Crop straw burning can polluted air in the open, harm people ' s health, especially on airport, near Highway burning can affect traffic safety, causes the aircraft grounding, car tracing cauda collision, shade tree such as is burnt at the adverse consequences.Although various places government has all put into effect the regulation of forbidding Open Burning Crop Residue at present, open incineration agricultural crop straw still remains incessant after repeated prohibition, and environment causes severe contamination, causes tremendous economic loss to society.
When the biomass waste resources such as stalk are wasted; the current main fossil energy such as the combustion gas that uses in China's industrial and agricultural production, fuel oil, heat energy, coal, oil reduces day by day; famine; energy dilemma has become the bottleneck problem of the world and social development, is current problem in the urgent need to address.
China has a large population and a few land, particularly the arable land of agricultural has approached red line.In agriculture production, need a large amount of agricultural chemicals, inorganic fertilizer by life-time service for improving grain, reach prevention and elimination of disease and pests, improve the object of grain yield.Due to the life-time service of agricultural chemicals, inorganic fertilizer, utilization ratio is low, causes residual in soil and farm crop.Cause soil, water source, grain, vegetables, fruit to pollute.Pesticide residue in grain, vegetables, fruit have jeopardized health of human body safety, affect the raising of life in the countryside level and quality.
Along with social fast development, people more and more add attention for energy-saving and emission-reduction and ecological environmental protection, constantly seek to use the new energy, control atmosphere pollution, and energy-saving and emission-reduction, reduce Greenhouse effect.The technology that is comprehensively converted into available stock with biomass waste resources such as agricultural crop straw, ight soil, chaff slags has caused showing great attention to of departments at different levels of government.
The biomass waste resource trans-utilization technology that the comprehensive trans-utilization technology of biomass pyrolytic is current comparative maturity.In the high temperature powdered carbon producing in gasifying biomass, charing pyrolytic process and high-temperature gas mixture body, be mixed with the available materials such as amount of heat, biological tar, biological acetic acid, biological flue gas, biological flue gas before use must be by heat, biological tar, biological acetic acid separated out, and by biological hot gas cooling.The most of water washing cleaning separating device that adopts of separating equipment for purification of the high-temperature biological mixed gas in current existing biomass pyrogenation gasification, pyrolysis charring device.In purification separation process, biological tar, biological acetic acid and heat are discharged with washing water,, pyrolysis conversion product can not get separating effectively completely, collecting utilization, causes the waste of secondary pollution and twice transformation resource.
