Abstract
The invention discloses environmental friendly sulfur-fixation and dust-fixation biomass briquette. A sulfur-fixation combustion improver is added. By cooperation of components in the combustion improver, flue gas generated during the briquette combustion process is turned into coal gas, flame is increased, and emission of lots of fume and harmful gas is reduced. Meanwhile, biomass generated by fermentation is modified with a sodium hydroxide solution, lye releases -OH which enters lignin of biomass' cell walls to destroy pyranoid ring in lignin, separate cellulose and hemicellulose tangled in lignin and relieve a spatial three-dimensional cross-linked network structure of lignin and hemicelluloses. Through recombination, a complex spatial network structure is formed, and cohesiveness is raised, briquetting pressure is then reduced, and abrasion of equipment is relieved. The prepared biomass briquette has excellent sulfur-fixation and dust-fixation effects and high biomass utilization rate, is energy-saving and environmental friendly, has good slag form after combustion, and can be used as boiler coal or used for a domestic small civil boiler.
Description
Technical field
The present invention relates to Filter Tuber For Clean Coal applied technical field, be specifically related to a kind of environmental protection sulphur-fixing and dust-fixing biomass coal and preparation method thereof.
Background technology
Biomass such as straw is the primary solids garbage of China's agricultural production, and stacking processes and occupied a large amount of agriculture plantation, and crop straw burning can cause air pollution, and the minimizing degree of compost is low.In order to realize the recycling of garbage, strengthen the dynamics of digestion agricultural stalk, have people to be added in clean moulded coal as binding agent by straw.
Biomass coal is that disposable energy of coal and regenerated biological energy biomass are organically combined; it it is a kind of novel composite fuel; it it is the new product that combines of energy technology, emission-reduction technology and clean coal technology; accelerate biomass coal industrialization; effective new way is opened for agricultural, industrial organic wastes energy; to energy-saving and emission-reduction, preserving the ecological environment has great importance, and meets country and reduces discharging potentiation long-range developmental program.But the biomass coal produced in prior art is due to the defect of biomass self rigidity, easy swelling cracking after extruded with coal dust, and pure inflammable, the burning persistency difference of biomass coal etc., thus take effective technology scheme by addition modified for biomass or add effective additive and improve the function of existing biomass coal, it is achieved reduce discharging CO2、SO2, reduce flue dust and PM2.5, save the multiple-effect of coal resources.
" preparation of biomass coal and Micro-Structure Analysis " literary composition is to solve biomass rigidity to cause a difficult problem for biomass coal swelling cracking, microbial fermentation technology is utilized to process biomass straw, using fermenting, modified biomass blend as additive by a certain percentage with fine coal, and cold moudling prepares biomass coal.Result shows: modified biomass quality of fermenting is closely knit, expands compression performance and is improved, and after activation, big particle diameter is the filament being wound around mutually, reuniting, and it is preferable that small particle sprawls effect, and has covering property；Fermentation makes straw tissue become loose, and beneficially coal grain is combined with biomass, it is to avoid biomass have a rigidity and cause moulded coal swelling cracking；After before modified, caloric value change is less, for 0.07kJ/g.Biomass coal optimum proportioning is: coal 80%, fermentation of biomass 15%, bentonite 5%；The comprcssive strength preparing moulded coal reaches 1.4MPa, and drop strength is up to 98.65%, and heat stability reaches 88.4%.
But it is the highest to the utilization rate of biomass in literary composition, briquetting pressure big equipment attrition phenomenon is serious, the modified moulded coal comprcssive strength prepared and drop strength is relatively low is unfavorable for long-term storage and transport, excessive being obviously unfavorable for realizes saving coal resources and reducing discharging CO coal usage ratio2、SO2Reduce flue dust and the combustion requirements of PM2.5, blindly increase that the content of biomass inevitably results in again that the smog of moulded coal is big, efficiency of combustion is low, calorific value is little cannot meet thermal discharge and require that high place uses, it is therefore desirable in addition modified to obtain biomass coal fuel energy-conservation, efficient, that clean to existing moulded coal production technology.
