Description
Technical field
The present invention relates to the gas purification equipment for purifying in equipment that utilizes of the waste resources such as a kind of industrial organic solid-state castoff, agricultural biomass discarded object, specifically a kind of taking agricultural crop straw the purification device in main living beings waste resource pyrolysis gasification system.
Background technology
China is a large agricultural country, has produced the biomass resource such as a large amount of agricultural crop straws, chaff slag in agricultural production and processing of farm products.Traditional utilizes mode mainly as home energy source, feed, fertilizer, the raw material of industry and construction material.Along with the fast development of agricultural technology modernization and agricultural 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 improving constantly, agricultural crop straw is constantly declined as the quantity of the energy, and commercial energy (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 agricultural production is substituted by inorganic fertilizer, and life of farmers and agricultural production stalk used sharply declines.Meanwhile, agricultural crop straw output is with crops, particularly the increase of cereal crops 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 contaminated 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 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 crisis 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 agricultural production, need a large amount of agricultural chemicals, inorganic fertilizers to be used for a long time for improving grain, reach prevention and elimination of disease and pests, improve the object of grain yield.Due to the long-term use of agricultural chemicals, inorganic fertilizer, utilization rate is low, causes residual in soil and crops.Cause soil, water source, grain, vegetables, fruit to pollute.Residues of pesticides 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 effects.The technology that is comprehensively converted into available resources with living beings 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 thermal cracking of living beings refers to the thermal cracking of living beings (comprising sawmilling, firewood, weeds, pine needle leaf, crop material, edible fungi residues) under the condition of anoxic or limited oxygen supply completely, finally forms the process of fuel gas, tar, acetic acid and heat.The thermal-cracking method of living beings comprises that limit oxygen heat-transmission solution, limit oxygen charcoal (gas) heat-transmission solution, over dry heat up in a steamer pyrolysismethod, according to the difference of reaction condition and product, biomass pyrolysis device divides again biomass pyrogenation gasification stove, the biomass pyrolytic carbon (gas) of the oxygen that is limited to change stove and anoxybiotic carbonization charcoal (gas) is changed stove etc.
Biomass pyrolytic technology is the biomass resource trans-utilization technology of current comparative maturity, but the purification of pyrolysis conversion product, separation, collecting device in existing biomass pyrogenation gasification device are perfect not enough, and conversion product collection utilization rate is not high.The for example purification of pyrolysis conversion product, separation, the collecting device in existing biomass pyrogenation gasification device mostly adopts wet (washing pouring) method purification separation.Existing drip washing device efficiency is low, purifies not thoroughly, and drip washing can not get effective utilization with treatment fluid, and in gas, is mixed with a large amount of liquid particles after drip washing, and gas is caused to secondary pollution, thus cause can be to follow-up equipment the infringement such as corrosion.
