Embodiment 1

[0020] Disclosed is a Nandi biomass fuel, which is obtained by mixing carbonized material obtained by pulverizing and carbonizing Nandi stalks with corn stalk powder obtained by crushing corn stalks, adding them to a biomass molding machine and pressing them.

[0021] Further, the mixing mass ratio of the carbonized material to the corn stalk powder is 1.2:3.

[0022] Further, the preparation method of the carbonized material is:

[0023] (1) Modification

[0024] Crush the stalks of Nandi to 90 meshes to obtain the powder of Nandi stalks. After soaking the powder of Nandi stalks in a strong oxidizing acid solution with a mass fraction of 3.5% for 2.5 hours, the mixing ratio of the powder of Nandi stalks and the nitric acid solution is 120g: 400mL, then add potassium acetate with a mass of 1.2% to the nitric acid solution, stir at a speed of 200r / min for 2 hours, then filter, wash with water until neutral, and dry in vacuum to obtain modified Nandi stalk powder;

Abstract

The invention discloses a triarrhena lutarioriparia biomass fuel, and relates to the technical field of biological environment protection. The triarrhena lutarioriparia biomass fuel is prepared through mixing a carbonized material which is obtained by grinding and carbonizing triarrhena lutarioriparia stalks with corn stalk powder which is obtained by grinding corn stalks, and adding the mixture into a biomass forming machine to carry out pressing. The triarrhena lutarioriparia biomass fuel is prepared through interaction of the triarrhena lutarioriparia stalks and the corn stalks, so that waste materials are utilized; and meanwhile, the triarrhena lutarioriparia stalks are carbonized to a certain extent, so that a carbon content in the biomass carbon fuel can be effectively adjusted and alagging rate of the biomass carbon fuel can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of biological environmental protection, and in particular relates to a Nandi biomass fuel. Background technique [0002] my country is a country with a large output of straw, and the pollution of crop straw has always been the bottleneck of agricultural development. According to the biomass conversion pathway, current biomass energy utilization technologies include physical conversion, biological conversion and chemical conversion. The physical conversion is mainly physical compression and briquetting treatment to prepare biomass solid briquette fuel. [0003] The corn stalk biomass fuel prepared by the prior art has relatively low combustion heat, which leads to the disadvantages of high production cost and low utilization rate. Contents of the invention [0004] The purpose of the present invention is to provide a kind of Nandi biomass fuel aiming at the existing problems. [0005] The present inventi...
