Description

Swinging controlled pyrolysis carbonizing kiln
Technical field
This utility model relates to scrap digestion field, particularly relates to swinging controlled pyrolysis carbonizing kiln.
Background technology
Fixed-end forces typically refers to solid waste is converted into, by physics, chemistry, biology, materialization and biochemical method, the process being suitable to transport, store, utilize or dispose.How auspicious the technology of fixed-end forces is multiple, have landfill, compost, burn, pyrolysis etc..Wherein burn and pyrolysis belongs to heat treatment technics.Heat treatment technics occupies dominant position the most in the world.Make a general survey of the developing history of developed country's solid waste heat treatment technics, be broadly divided into three phases.
One is incineration technology (first generation solid waste heat treatment technics).Solid waste burning technique functions comes from the Britain in industrial revolution period.First sludge incinerator was born in Britain in 1870 in the world, and came into operation.Supreme century 70, incineration technology is through century-old skill upgrading and performance improvement, and the exploitation application of the progress of flue gas ash removal technology and desulfurization removing nitric technology, and its performance reaches its maturity, and burns the atmospheric pollution brought and is also greatly reduced.In this stage, the type of furnace of sludge incineration is mainly grate furnace and fluid bed furnace.China uses sludge incineration technology to be the Japanese Martin furnace that Shenzhen in 1985 introduces first, and the most domestic rubbish power processes and all uses mud fields landfill.Solid waste burning technology is the most ripe through the development of more than 100 years.But it is to the process of atmospheric pollution or unsatisfactory.Facts have proved.Although can temporarily remove two English by high-temp combustion.But temperature reduces during waste heat recovery.Cause two English to regenerate and stick in a large number in flying dust.This be there is presently no effective treatment technology, become serious environment hidden danger.As sludge incineration power plant, 5, Wuhan City produces about 500 tons of flying dusts every day.Containing a large amount of two English in flying dust.So far cannot obtain standardization processing, become the generally worry of the public.
Two is pyrolytic gasification technology (second filial generation solid waste heat treatment technics).In view of sludge incineration technology deficiency in terms of processing atmospheric pollution.Western countries start the research and development second filial generation solid waste heat treatment technics based on pyrolytic gasification from the seventies in last century.The most former hydraulic stretching forming machine key common technology of pyrolytic technique and the applied research exploitation of technique are the weakest.On the other hand, in the face of the most urgent international and domestic end product price station, forcing middle end product parts cost control pressures, reducing the material consumption in industrial processes and being considered reason is in isolation air (oxygen) and the environment of uniform temperature, makes Hydrocarbon decomposes.Form the materials such as gas phase (pyrolysis gas), liquid phase (pyrolytic behavior) and solid phase (solid residue).It is different from incineration technology and all process materials are knocked down hearth combustion, thus bring the environmental problems such as secondary pollution.Pyrolysis is that by pyrolytic process the organic pollution processed in material is changed into the gaseous state cleaning fuel based on biogas and hydrogen, more in addition heat energy utilization, and remaining polluter also therefore is solidificated in pyrolysis residue.Through 30 years of researches and development, solid waste pyrolytic technique has been successfully applied to the cities, field such as existing at solid waste and biomass recycling use in developed country.In terms of innoxious, minimizing, stabilisation and the resource of fixed-end forces (particularly mud and mud) with the obvious advantage.1985, first solid waste pyrolysis power plant (process mud mud and industrial waste is main) was put into operation in Boolean, Germany height city.Over 30 years, this project is the most properly functioning.And become the whole world fixed-end forces clean technologies the bad care and education of infants educate and visit base.
Three is " plasma " treatment technology (third generation solid waste heat treatment technics).Plasma processing techniques.Also known as " zero-emission effect " technology.Being developed by German company, first plasma sludge disposal technology project put into operation in Poland in 2009, and day processes 190 tons.Mud is after plasma heating furnace processes, and product is liquefied natural gas and residue, without Air Pollutant Emission.
Enter 21 century, along with quickly propelling of Urbanization in China.The generation amount of mud and mud also sharply increases, and becomes the environmental problem that various places are urgently to be resolved hurrily.According to statistics, between calendar year 2001 to 2014 year, I increases sharply to 32.3 hundred million tons from about 900,000,000 tons because of the generation amount of Industrial Solid Waste, increases by 12% every year.But China's solidification disposal of waste industry is started late, the most still using landfill process, the application that compost, place's burning method dispose solid waste is the most universal.
At present, the basal conditions of industry at China's solid waste: one be industrialization level and the market concentration the lowest;Two is owing to fixed-end forces industry is the most at an early stage of development.Rung by factor shapes such as support on policy, concept, technical matters.Competition lattice are the most finally established for two innings.The market competition is in disordered state.Domestic sludge burns field.Jinzhou environment, the wide world, TEDA in Tianjin, pioneering group, the throwing of Shanghai ring, Veolia, Sang De environment (former conjunction adds resource), big bright environmental protection, Feng Quan environmental protection, the green power in Shenzhen, Hangzhou Na Jiang Deng Shiyujia enterprise account for row 7 part poles, whole market;Composting process aspect, the most only Sang De environment Shu Gan large enterprise.The competitor's quantity possessing considerable strength in China's fixed-end forces industry is the most very limited, and the non-state-owned enterprise such as Sang De environment, rare, the big bright environmental protection of Jinzhou ring becomes increasingly conspicuous based on technology and pusher side advantage, competitive strength.And a few big city environmental sanitation group is by means of fund, regional superiority.And introduce overseas containing workshop.Mega project also takes up certain market share.
Both at home and abroad on the research of pyrolysis biomass charcoal making mainly at final temperature, heating rate, biomass components etc. on aspects such as the impacts of charcoal processing and biomass carbon performance study, in biomass carbon performance study, research and utilization biomass carbon improves the more of soil and preparing active carbon.The also coproduction to charcoal processing He gas processed of some researcheres is studied.The research of researcher both at home and abroad is mainly carried out on temperature programming electric furnace, thermal analyzer, sets heating rate, outlet temperature, then analyze carbon yield, fixed carbon content, carbon structure etc. during experiment.The research of this project finds that the key factor affecting biomass pyrolytic is the heat that the external world passes to biomass, and heating rate, outlet temperature are the sign factor of heat output.But the document relating to being pyrolyzed biomass charcoal making heat transfer research at present is the most relatively fewer, biomass pyrolytic is being modeled in the document of heat transfer research, more with biological particles as object of study, and size is less, and more more complex than to the heat transfer of biological particles to the phenomenon of Heat of biomass in reality.The industrialization of biomass charcoal making it is pyrolyzed after the purpose of research should be to promote now, energy density should be used during commercial Application high and there is the biomass material of the biggest size, the utilization strengthening molding biomass is a kind of development trend, so research external heat source is highly significant to the heat transfer of molding biomass.The pyrolysis thermal source of researchers mostly is electric power at present, and electricity is a kind of high-quality energy, should be taken into account its economy during the consumption high-quality energy, so industrial applications intermittent fever solution thermal source is considered as using fume afterheat etc..Flue gas phenomenon of Heat on the phenomenon of Heat of biomass and the temperature programming equipment with electricity as thermal source has bigger difference.High-temperature flue gas conducts heat to molding biomass biomass in the way of radiation and convection current, and flue gas temperature after biomass are conducted heat reduces.And temperature programming equipment mainly conducts heat to biomass in the way of radiation, after biomass are conducted heat, temperature programming equipment still continues to raise according to certain heating rate.Even so, but both phenomenon of Heats there is also important relation in pyrolysis impact, and the intermediary of both contacts is the heat of transmission, i.e. transmission gives biomass how many heats and pyrolytic process will cause great impact.
Charcoal is one of energy basic in commercial production and daily life, and in recent years due to the increase of demand, forest department, for protecting forest resources and ecological balance, forbids that indiscriminate felling of trees and becoming a useful person is made charcoal so that Linesless charcoal imbalance between supply and demand day is becoming tight.Then biomass carbon arises at the historic moment, and effectively alleviates the situation that Linesless charcoal is in short supply.Biomass carbon, compared with conventional charcoal, has the advantage that with garbage for raw material to replace timber, turns waste into wealth, turn harm into good, and is conducive to protecting forest resources and maintaining ecological balance, alleviates the pollution to environment.
Biomass pyrolytic carbonization equipment includes two types, i.e. kiln formula thermal decomposition coke oven and fixed-bed type pyrolysis charring reacting furnace.Wherein kiln formula thermal decomposition coke oven is the novel furnace of development on the basis of tradition earth kiln charring process, the gas-liquid product in pyrolytic process can be reclaimed while producing charcoal, being concentrated mainly on the research of kiln formula carbonization body of heater the most both at home and abroad utilizes modernization process and manufacture means to improve on tradition body of heater, a lot of kiln formula retort patent has occurred.This kind of charcoal processing mode is wayward to temperature rise, and based on experiential operating, charcoal processing difficult quality reaches optimal, and with burn a part of coal or timber to realize external heat.Charcoal processing place in the wild, can only add the cost of transportation of raw material and product, and charcoal processing pyrolysis gas can only discharge, and causes the waste of energy.
Fixed-bed type carbonization device can be divided into again outer fuel heated type and internal combustion type according to the difference of heat transfer type: external heating type fixed-bed pyrolysis carbonization system comprises heating furnace and pyrolysis oven two parts, external heat body of heater thermotropism solution stove provide pyrolysis required energy.Heating furnace many employings tube furnace, its great advantage is that temperature is easy to control, accurate, can improve Biomass Energy Utilization rate, improves pyrolysis product quality, but need to consume the energy of other form.The combustion system of internal combustion type fixed-bed pyrolysis retort is similar to traditional kiln formula retort, need to light biomass fuel in stove, and the heat relying on fuel own combustion to be provided maintains pyrolysis.Internal combustion type retort is the different of heat transfer mode from the maximum difference of external-heat, and external-heat is conduction of heat, and internal combustion type retort is conduction of heat, thermal convection current, the combination of three kinds of transfer modes of heat radiation.Internal combustion type fixed-bed pyrolysis retort pyrolytic process does not consume any additional heat, reaction itself and raw material drying all utilize biomass self heat production, the thermal efficiency is higher, but biomass material consumes bigger, and in order to maintain the anaerobic environment of pyrolysis, burning insufficient, heating rate is relatively slow, and in pyrolytic process, temperature rise is wayward.
