Abstract
The invention discloses a device for smokeless carbonizing treatment on crop straws. The device consists of a carbonization furnace and a purifying device, wherein the carbonization furnace comprises a furnace cover clamped and inserted with an insulating material asbestos board, a furnace body shell, a carbonization chamber, a bottom plate, an ash discharging port, a smoke pipe, a furnace door and a wind inlet; and the purifying device comprises a smoke tee, an axial flow AC blower, a PPR adapter, a spray header, a corrugated tube, a PPR tee, a control ball valve, a magnetic drive circulating pump, an outside ball valve, a stainless steel frame and a collecting barrel. The air pollution problem in the carbonization process is greatly solved, and plenty of generated PM2.5 and PM10 particulate matters are completely absorbed through a spraying and spiral purifying secondary system. The quality of the produced biomass charcoal is high. Because the input quantity of the oxygen in the whole carbonization process is low, the shortcoming of inaccurate oxygen quantity controlled by men is avoided; and except a small quantity of the ash contents are generated in the furnace mouth due to ignition, the other straws are uniformly carbonized and the biomass charcoal almost has no ash content.
Description
Technical field
The present invention relates to straw environment protection charring process field, be specifically related to a kind of device agricultural crop straw being carried out to smokeless environment-friendly charing process.
Background technology
China is a large agricultural country, a large amount of agricultural crop straw can be produced in agriculture production, for straw, the output of national paddy in 2012 is about 2.01 hundred million tons of (Chinese agriculture yearbooks, 2012), the straw along with 1-1.5kg is produced (Karimi etc., 2006 by per kilogram paddy, Biomass and Bioenergy), therefore annual straw output is 2.01-3.01 hundred million tons.If by Returning Application of Crop Straw, quantity is too large and unrealistic on the one hand; The more important thing is, the most of organism being restored to field will be decomposed by the microorganisms gradually, and discharge CH in air
4, N
2o and CO
2isothermal chamber gas (Zou etc., 2005, Global Biogeochemical Cycles).Directly burnt by crop material, will produce the particulate matters such as a large amount 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 atmospheric polluting material, more becomes nationwide problem of environmental pollution in recent years.The PM2.5 that field naked light burns the generation of wheat, corn and rice straw can reach 7.2-39.0 g/kg (Zhu Bin etc., 2005, Research of Environmental Sciences), the research such as Wang shows, biomass combustion reaches 3.0-16.8% and 4.0-19.0% (Wang etc. respectively to the contribution of PM2.5 in Beijing and Guangzhou air, 2007, Atmospheric Environment).
Under the condition of anaerobism or anoxybiotic, organic materials is carried out pyrolysis, a kind of solid matter of similar black wood charcoal can be generated, be generally referred to as biomass charcoal (Lehmann, 2007, Nature).Biomass charcoal is organic materials products of incomplete combustion, it is rich in the nutrient needed for the farm crop such as K, Ca, Mg and P, the fertility (Lehmann and Rondon, 2006, Biological Approaches to Sustainable Soil Systems) of soil can be improved; And general in alkalescence, the modifying agent of acid soil can be used as, reduce soil acidity (Yuan etc., 2011, Bioresource Technology), improve the output of farm crop; Biomass charcoal surface, with a large amount of negative charge, 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).Simultaneously biomass charcoal specific surface area and surface charge density high, be rich in organo-functional group, heavy metal and organic pollutant have very strong absorption property, can be used on organic and process (Pan etc., 2014, Chemosphere of inorganic wastewater; Yuan Min etc., 2012, ecological and rural environment science journal), also can be used for reparation (Jiang etc., 2012, the Journal of Hazardous Materials of heavy-metal contaminated soil; Jiang etc., 2012, Chemosphere).And carbon can effectively be sealed up for safekeeping by biomass charcoal, biomass charcoal in being manured into soil has very high stability, not easily decomposed (Steinbeiss etc. by soil microorganisms, 2009, Soil Biology & Biochemistry), biomass charcoal is to increase carbon base in soil reserves, reduce Global Emissions of Greenhouse Gas, maintain the significant (Lehmann of ecosystem carbon balance, 2007, Nature), biomass charcoal even may become the important way (Pan Genxing etc. of the carbon transaction alleviating climate change, 2010, ecology and rural environment journal).
But the PM2.5 produced in stalk smoldering process 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 do not take the measure of flue in biomass charcoal preparation process, more serious atmospheric pollution will be caused on the contrary.In addition, the many devices at present for the preparation of biomass charcoal adopt Outside Heating Method, need to consume mass energy, if utilize the heat discharged in agricultural wastes pyrolytic process to make it carbonize, also will greatly reduce energy consumption and the preparation cost of biomass charcoal.
Summary of the invention
the technical problem solved:the invention provides a kind of device agricultural crop straw being carried out to smokeless charing process.The biomass charcoal utilizing crop material to produce can be used for improvement soil, processes waste water, seals 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 (
