Description
Technical field
The present invention relates to straw environment protection charring process field, be specifically related to a kind of device that agricultural crop straw is carried out smokeless environment-friendly carbonization process.
Background technology
China is a large agricultural country, agricultural production can produce a large amount of agricultural crop straw, as a example by Caulis et Folium Oryzae, the yield of national Oryza glutinosa in 2012 is about 2.01 hundred million tons of (Chinese agriculture yearbooks, 2012), Caulis et Folium Oryzae along with 1-1.5kg is produced (Karimi etc., 2006, Biomass and by per kilogram Oryza glutinosa
Bioenergy), therefore annual Caulis et Folium Oryzae yield 2.01-3.01 hundred million tons.If by Returning Application of Crop Straw, on the one hand quantity is the biggest and unrealistic；The more important thing is, the most of Organic substance being restored to field will gradually be decomposed by the microorganisms, and discharge CH in air4、N2O and CO2Isothermal chamber gas (Zou etc., 2005, Global
Biogeochemical Cycles).Directly being burnt by crop material, will produce the particulate matters such as substantial amounts of PM2.5 and PM10, at crop harvesting a large amount of crop straw burning in season, the PM2.5 of generation has become the important sources of atmosphere pollution, more becomes the most nationwide problem of environmental pollution.Field naked light burns the PM2.5 of Semen Tritici aestivi, Semen Maydis and rice straw generation up to 7.2-39.0 g/kg (Zhu Bin etc., 2005, Research of Environmental Sciences), the research such as Wang shows, biomass combustion has respectively reached 3.0-16.8% and 4.0-19.0% (Wang etc. to the contribution of PM2.5 in Beijing and Guangzhou air, 2007, Atmospheric
Environment)。
Under conditions of anaerobism or anoxybiotic, organic materials is pyrolyzed, the solid matter of a kind of similar black wood charcoal, commonly referred to as biomass carbon (Lehmann, 2007, Nature) can be generated.Biomass carbon is organic materials products of incomplete combustion, and it is rich in the nutrient needed for the crops such as K, Ca, Mg and P, can improve soil fertility (Lehmann and Rondon, 2006, Biological
Approaches to Sustainable Soil Systems)；And be typically alkalescence, can serve as the modifying agent of acid ground, reduce soil aciditiy (Yuan etc., 2011, Bioresource
Technology), the yield of crops is improved；Biomass carbon surface, with a large amount of negative charges, significantly improves nitrogenous fertilizer and phosphate fertilizer utilization efficiency (Jiang Jun etc., patent of invention, ZL 201210488366.9 by changing soil property;Jiang etc., 2015, Soil and Tillage
Research).Biomass carbon specific surface area and surface charge density are high simultaneously, have the strongest absorption property rich in organo-functional group, heavy metal and organic pollution, can be used on organic and inorganic wastewater process (Pan etc., 2014, Chemosphere;Yuan Min etc., 2012, ecological and rural environment science journal) it can also be used to reparation (Jiang etc., 2012, Journal of of heavy-metal contaminated soil
Hazardous Materials;Jiang etc., 2012, Chemosphere).And carbon can effectively be sealed up for safekeeping by biomass carbon, the biomass carbon in being manured into soil has the highest stability, is difficult to be decomposed (Steinbeiss etc., 2009, Soil Biology & by soil microorganism
Biochemistry), biomass carbon is to increasing carbon base in soil reserves, reduce Global Emissions of Greenhouse Gas, ecosystem carbon is maintained to balance significant (Lehmann, 2007, Nature), biomass carbon possibly even becomes the important way (Pan Genxing etc. of the carbon transaction alleviating climate change, 2010, ecological and rural environment journal).
But the PM2.5 produced during straw smoldering is 2.4-11.5 times of naked light, up to 67.6-104.6 g/kg (Zhu Bin etc., 2005, Research of Environmental Sciences).If biomass carbon preparation process is not taked the measure of purifying smoke, will result in more serious air pollution on the contrary.It addition, the many devices being currently used for preparing biomass carbon use Outside Heating Method, needing to consume mass energy, if utilizing the heat of release in agricultural wastes pyrolytic process to make its carbonization, also will be substantially reduced energy resource consumption and the preparation cost of biomass carbon.
Summary of the invention
Solve the technical problem that:The invention provides a kind of device that agricultural crop straw is carried out smokeless carbonization process.The biomass carbon utilizing crop material to produce can be used for improveing soil, processing waste water, seal carbon etc. up for safekeeping.This device is the feature produced according to crop material smoldering and flue gas, improve our existing straw carbonizing apparatus (Utility modelPatent, CN201962245U), increase flue gas purification system, be finally reached optimization carbonization process, improve biomass carbon product quality, eliminate the purpose of the airborne particulates (PM2.5 and PM10) produced in carbonization process.
Technical scheme:A kind of device that agricultural crop straw carries out smokeless carbonization process, forms including retort and purifier two parts；Described retort includes the bell clamping insulation material asbestos board, body of heater shell, carbonization chamber, base plate, and ash mouth, chimney, fire door and air inlet, carbonization chamber bottom is provided with stoveGrateInsulation material refractory brick it is filled with between body of heater shell and carbonization chamber, air inlet is positioned on the opposite body of heater of fire door and ash mouth, the both sides on retort top are located at by chimney, and bell is rotationally connected with body of heater shell by hinge, and bell is closed by the buckle being located on body of heater shell, ash mouth is positioned at the bottom of body of heater, fire door is located on ash mouth, and whole body of heater is placed on base plate, and the central authorities of bell are provided with thermometer；Described purifier includes flue gas threeway, axial flow AC blower fan, PPR adaptor, spray head, corrugated tube, PPR threeway, control ball valve, magnetically-actuated circulating pump, outside ball valve, stainless steel frame and collecting vessel, described retort chimney is connected by drain flue with the flue gas threeway of purifier, and flue gas threeway is provided with axial flow AC blower fan, and axial flow AC blower fan is connected with PPR threeway by reducing the PPR adaptor of bore step by step, the another two ends of PPR threeway are connected with corrugated tube and spray head respectively, and spray head scalable water smoke size is also provided with control ball valve；Spray head is connected with collecting vessel bottom outside ball valve through hose connection magnetically-actuated circulating pump, the connect flexible pipe of the magnetically-actuated circulating pump other end；Corrugated tube imports collecting vessel around stainless steel frame spiral.
