Problems solved by technology

[0003] The technical problem to be solved by the present invention: In view of the low combustion calorific value and large consumption of biomass fuels, insufficient combustion and a lot of ash during use, the flue gas generated during combustion seriously corrodes combustion equipment and endangers human beings. For safety issues, it provides a method of feeding cattle with cotton stalks and corn, collecting cow dung and soaking it with biogas liquid to convert it into sludge, then extracting humus from the sludge, using Enteromorpha and corn silk to hydrolyze and ferment to prepare combustible phytoalcohol, and finally Phytoalcohol, humus and open-cell foaming agent compound injection molding, the method for finally making biomass fuel

example 1

[0019] Firstly, the cotton hemp stalk was mixed into the silage corn to feed the cattle according to the doping amount of 10%, and the feeding was continued for 20 days, the feces discharged by the cattle during the feeding period were collected, and the cow dung was exposed to the sun for 15 days to obtain dry cow dung; Build a square reaction tank with a side length of 10m and a depth of 1m, transfer 2000kg of dry cow dung obtained above into the reaction tank, and then pass the biogas liquid in a 50t biogas tank into the tank, and ferment naturally at 35°C for 30 days Until the cow dung is converted into sludge; then fish the sludge converted from cow dung in the reaction tank, mix the sludge and potassium aluminum sulfate dodecahydrate at a mass ratio of 100:1 and let it stand for 14 hours to separate the solid and liquid, and extract the upper liquid Finally, the lower layer of humus is obtained, which is for subsequent use; after mixing Enteromorpha and corn silk in a mas...

Abstract

The invention relates to a preparation method of ash-free high calorific value biomass fuel, and belongs to the technical field of biomass fuel preparation. The preparation method comprises the steps of firstly using rich content of microorganisms in cow rumen to conduct the preliminary degradation of cotton rods and corn with high fiber content, using biagas fluid for deep layer degradation to transform the macro-molecular organic compounds into low molecular weight organic matter, and remove inorganic impurities, thus not only increasing the organic carbon content in humus, but also decreasing the length of organic carbon chain to enhance combustion efficiency, using phytol as a volatile combustible, and mixing the phytol with the humus, using butter as the phytol curing agent, and under the effect of an open porous foaming agent acquiring the biomass fuel with rich pores on the surface. The ash free high calorific value biomass fuel prepared by the method has the advantages of having the features of full combustion, leaving no residues after combustion, having high calorific value reaching more than 24.62MJ / kilogram, generating no toxic gas during combustion, having no corrosive effect to combustion equipment, and having a wide application prospect.

Description

technical field [0001] The invention relates to a method for preparing an ash-free high calorific value biomass fuel, belonging to the technical field of biomass fuel preparation. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass briquette fuel, which uses agricultural and forestry waste as raw materials, and through crushing, mixing, extrusion, drying and other processes, it is made into various shapes such as lumps, granules, etc., which can be directly A new type of clean fuel to burn. So far, the development ...
