Problems solved by technology

There are also endless reports about biomass fuels, such as Chinese patent publication number CN105542893A using herbivorous animal manure, agricultural waste, waste oil, calcium oxide, calcium sulfate, propionic acid, kaolin, diatomaceous earth, bentonite, calcium peroxide, Aluminum hydroxide, propylene glycol, polyvinyl alcohol, oxygen enhancer, anti-shock and anti-explosion agent, combustion accelerant, and loosening agent have prepared biomass fuel with combustion and no harmful gas. Chinese Patent Publication No. CN103666623A adopts straw powder, peanut shell and wood powder The method of mechanical processing and direct molding has prepared biomass fuel with high calorific value. However, the problem of bagasse fuel at present is mainly the processing of bagasse. Bagasse is neither soluble in water nor organic solvents, and cannot be melted when heated. Generally, acid and alkali treatment are easy to cause water pollution, and the cost of enzymatic hydrolysis alone is high, and the product after bagasse combustion is easy to agglomerate, causing blockage of the combustion furnace and low combustion efficiency

Embodiment 1

[0017] A bagasse fuel in this embodiment consists of the following ingredients in parts by weight: 100 parts of modified bagasse, 40 parts of waste oil, and 20 parts of bulking agent.

[0018] A method for preparing bagasse fuel, the specific steps are as follows: Weigh each component by weight, put 100 parts of bagasse in phosphoric acid with a concentration of 6%, at a temperature of 125°C, and an acid treatment time of 10 minutes, and let the water content After it is 40%, it is pulverized, the particle size is 1mm, and then the bagasse after pulverization and 20 parts of zinc chloride are ball milled and modified at a rotating speed of 1000r / min, and then added to the cellulase aqueous solution for 10min enzymatic hydrolysis, the temperature Keep it at 30°C, then blow dry the hydrolyzed bagasse to a moisture content of 10%, and finally add 40 parts of waste oil and 20 parts of a 150-mesh bulking agent mixed with diatomite, zeolite and attapulgite at a high speed of 1000r / mi...

Embodiment 2

[0020] The preparation method of the bagasse fuel in this embodiment is the same as that in Example 1, except that the bagasse fuel consists of the following components in parts by weight: 100 parts of modified bagasse, 30 parts of waste oil, and 15 parts of loosening agent.

Embodiment 3

[0022] This example is the same as Example 1, except that the bulking agent is mixed with the same quality of vermiculite, zeolite, diatomite and attapulgite, and the particle size is 200 mesh.

[0023] The bagasse fuel of Examples 1-3 was tested for physical properties, and the results were as follows: After detecting the combustion temperature, it was found that the combustion temperature of the bagasse fuel prepared in Examples 1-3 could reach 1310-1360°C, and the combustion temperature of common fuels was between 930°C, the combustion temperature is increased by about 30%, and the calorific value of the bagasse fuel prepared in the detection of combustion calorific value embodiment 1-3 is 4700-5100 kcal / kg, and the combustion of each ton of bagasse fuel is equivalent to 0.6 tons of standard coal, and No PM2.5 smoke was generated during the combustion process.

Abstract

The invention discloses a bagasse fuel and a preparation method thereof, and particularly relates to the field of new energy. The bagasse fuel uses bagasse as a main raw material, illegal cooking oiland a bulking agent are added, the method which combines phosphoric acid treatment, mechanical ball milling treatment and cellulose enzymolysis is used for bagasse treatment, then drying, pressing andcooling are conducted, and the bagasse fuel is prepared. The bagasse fuel prepared through the method is environmentally friendly and clean in combustion; the added illegal cooking oil has the functions of improving combustion energy and supporting combustion; the added bulking agent has the effects of preventing the bagasse against burning caking and improving the combustion efficiency.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a bagasse fuel and a preparation method thereof. Background technique [0002] The development of biomass energy has become an important way to reduce environmental pollution and alleviate the contradiction between energy supply and demand. According to different sources, biomass suitable for energy utilization can be divided into five categories: forestry resources, agricultural resources, domestic sewage and industrial organic wastewater, urban solid waste, and livestock and poultry manure. Biomass energy has the characteristics of renewability, low pollution, wide distribution, and total abundance. Bagasse is the main waste of the sugar industry, and it is also an important renewable biomass raw material. Biomass pellet fuel is the energy utilization method of biomass solid form, and it is also the simplest and most direct way of biomass energy utilization. on...
