Description
Technical Field
The invention relates to a preparation method of a mushroom bran waste biomass fuel, perfects the preparation method of the mushroom bran waste biomass fuel, and provides a new idea for the development of the edible mushroom industry.
Background
The mushroom bran, also called edible mushroom cultivation waste or residual material, is a residual substance in a culture medium after the cultivation of the edible mushroom, and the cultivation of the edible mushroom usually takes sawdust and straw as raw materials. In the process of cultivating edible fungi, after the fungus chaff is subjected to enzymolysis by the edible fungi, mycelium residues of the fungus chaff are changed into component compounds such as crude fibers with changed structures and qualities. Substances such as sawdust, cottonseed hulls, wheat bran and the like containing a large amount of cellulose and hemicellulose are generally used as culture substrates of edible fungi, the culture substrates can enable the edible fungi to secrete cellulase and xylanase, macromolecular substances are decomposed into small molecular substances [ Liu Ying, Zhang Jiang, Wang hong Dynasty, and the like ] under the action of enzyme, and a fungus furfurylase extraction and preparation method is researched [ J ]. Hunan agricultural science 2010(1):88-89 ], so that the edible fungi can grow better, and a certain amount of xylanase and cellulase are remained in fungus chaff left after the edible fungi are harvested. The degradation of lignin is realized by lignin degrading enzyme in the process of planting edible fungi. The fungus bran is pretreated by a hydrothermal or acid catalyst to provide accelerated enzymatic hydrolysis, which is further beneficial to biological processes [ Mahualian, Gong Zheng Jie, Chenxin, etc.. 3 edible fungus bran cellulase and xylanase partial enzymological properties [ J ]. Anhui agricultural science 2010,38(28): 15479-.
With the continuous deepening of agricultural industrialization, the edible fungus cultivation is industrialized, the cultivation amount is greatly increased, the amount of fungus chaff generated every year is correspondingly increased, and the edible fungus chaff is concentrated, so that sufficient attention is paid to the resource utilization of the edible fungus chaff. At present, a large amount of residual mushroom bran waste materials after industrial edible mushroom production are important components of biomass resources. The mushroom bran waste is prepared into a solid biomass fuel with a certain shape and high density by a fuel forming machine by adopting a mechanical pressurization method, namely the mushroom bran waste forming fuel. The mushroom bran after the growth of the oyster mushroom is pressurized and densified to prepare a columnar solid fuel, the fuel value of the columnar solid fuel is between 3400 and 4000 kilocalories and is close to half of 7000 kilocalories of standard coal, the ash content is about 5 percent, the sulfur content is less than 5 per thousand, and the columnar solid fuel is a high-volatility solid fuel [ Zhao Safan, Han Zhun, Wang Xin Jian, and the like ].
At present, most domestic fungus chaff waste fuel forming machines use foreign briquetting technology and feed forming machines for reference, and the defects of unreasonable structure, low production efficiency, high energy consumption and the like of the fungus chaff waste forming fuel machines in China are directly caused, so that popularization and application are influenced. The mushroom bran is waste after the cultivation of the edible mushrooms, and has the characteristics of uniform granularity, loose structure, low water content and the like. The fungus chaff has produced certain economic benefits in the planting of edible fungi, and if the fungus chaff is further utilized efficiently, the planting income can be additionally increased.
Disclosure of Invention
The invention aims to provide a preparation method of a mushroom bran waste biomass fuel, which is used for pretreating mushroom bran waste to reduce water and volatile substances, and then the mushroom bran waste enters a commonly used mushroom bran waste combustion forming machine at present to improve the production efficiency and reduce the energy consumption of the forming machine.
In order to solve the technical problem, the preparation method of the mushroom bran waste biomass fuel comprises the following steps:
(1) airing the mushroom bran waste at normal temperature: drying fresh fungus chaff used by edible fungus production enterprises in the natural ventilation place, wherein the fungus chaff is spread as far as possible or arranged in a staggered or # -shaped way, aiming at removing most external moisture, and the drying can be stopped when the surface of the fungus chaff becomes hard. In summer and autumn in southern areas, the air-drying is carried out for 5-7 days because of higher natural temperature, large ventilation quantity and high water loss speed; in winter and spring, the product should be kept for 10-15 days. The operation can greatly reduce the water content on the surface of the mushroom bran, and the original 50% water content can be reduced to about 35% after the mushroom bran is aired for 7-15 days, so that the use energy consumption of subsequent drying and forming equipment is remarkably reduced.
If the waste mushroom sticks are used, the polypropylene film wrapped by the waste mushroom sticks is removed, and most of external moisture is dissipated because the early mushroom sticks are aired, so that the mushroom stick main bodies are separated from the film, and the external film is easier to remove. The waste mushroom bran from bed, box or pot cultivation of edible mushrooms does not require this step.
(2) Crushing the mushroom bran waste: mechanically crushing the mushroom bran into uniform particles with the particle size of 3-5mm, and sieving to remove micro particles.
(3) Adjusting the pH value: the pH value of the waste mushroom bran of the edible mushrooms is usually slightly acidic (5.5-6.5), so that the pH value needs to be adjusted to 7.5-8.3 by adding alkali liquor, and the waste mushroom bran is slightly alkaline in neutral, so that a proper pH environment is provided for the subsequent addition of polyglutamic acid. Common alkaline substances such as calcium hydroxide and gypsum can be adopted, and the adding proportion is 2-5% (mass percentage).
(4) Adding 1.0-2.0 liters of colloidal solution when the water absorption of gamma-PGA per square meter reaches a saturated state: polyglutamic acid (gamma-PGA) is a water-soluble, non-toxic, biodegradable biopolymer; the water-absorbing material can absorb moisture in the surrounding environment, has larger expansion volume, and can also absorb heavy metals in the environment, such As Pb2+, Cu2+, Cd2+, Cr2+, Al3+, As4+ and the like to form precipitates. The common general opinion among people is that the edible fungi has large heavy metal content and is derived from cultivation materials; therefore, heavy metals in the waste mushroom bran remain, and these substances are also converted into environmental pollutants when being made into fuels at a later stage. For example, part of heavy metal (Cd) in the calcium superphosphate added to the cultivation material is enriched into the edible fungi through the growth and transformation of the edible fungi, and part of the heavy metal still remains in the fungus chaff waste material [ old subphyline, adsorption of five harmful heavy metals by common edible fungi and hazard analysis and evaluation [ D ].2016, south China university of agriculture ]. When the pH value of the polyglutamic acid is neutral and alkaline, the molecular form is in an extension state, the viscosity is increased, and the adsorption performance is improved. The invention adds gamma-PGA water extract to be uniformly mixed with the mushroom bran waste, after the gamma-PGA absorbs enough water to expand, the space around the gamma-PGA can be enlarged, the gap of the mushroom bran waste is enlarged, and the evaporation of the air-dried water is increased (the polyglutamic acid is added in the mushroom bran waste, the water can be absorbed and moisturized, after the polyglutamic acid absorbs enough water to expand, the space around the mushroom bran waste can be enlarged, the gap of the mushroom bran waste is enlarged, the diffusion of other volatile substances is facilitated, and the energy consumption of later-period drying is reduced); meanwhile, the gamma-PGA and various heavy metals in the fungus chaff are subjected to chelation reaction. After the operation for 3-5 days, the water content in the fungus chaff waste can be reduced to about 30%.
(5) Airing for 3-5 days: removing water introduced by adding the colloidal solution and water in the mushroom bran waste, and simultaneously giving time for the gamma-PGA in the colloidal solution to have chelation reaction with various heavy metals in the mushroom bran so as to fully contact and react.
(6) Processing and forming to prepare the biomass fuel: oven drying the waste mushroom bran under heating, squeezing, and oven drying at 60-65 deg.C for 4 hr or oven drying at 75-85 deg.C for 2 hr. Because the fungus chaff is pretreated (dried in the sun for 2 times and added with Gamma-PGA) in the earlier stage, the working condition of processing and forming is greatly reduced; at present, domestic enterprises are generally processed and molded under the condition of drying for 5-6h at 90-100 ℃, the energy consumption for preparing the biological fuel is reduced, the energy consumption required by early airing is taken from the nature, the burden of the enterprises is not additionally increased, and the purchase cost of the gamma-PGA produced by microbial fermentation is low (150 yuan/kg).
The method has the advantages of high efficiency, universality, rapidness, convenience and safety, the fungus chaff is pretreated on the basis of not increasing the production input cost of enterprises and extra energy consumption, the combustion performance of the biomass fuel obtained by adopting the fungus chaff waste material by the method meets the national relevant standard, the energy consumption of fuel preparation can be greatly reduced, the production benefit of the enterprises is improved, a new thought is provided for the domestic edible fungus industry, the production efficiency of the biomass fuel prepared from the fungus chaff is improved, and the combustion characteristic of the biomass fuel prepared from the fungus chaff is improved. The method can obviously reduce the energy consumption (electric energy) for preparing the biological fuel, and the energy consumption required by the previous airing is taken from the nature, so that the enterprise burden is not additionally increased; the biomass fuel prepared by the method can replace the traditional fuels such as coal, fuel gas, fuel oil and the like, the production cost of the fuel particles is as low as 600 yuan/ton, the market demand of the fuel particles is large, the average selling price is 750 yuan/ton and 1000 yuan/ton, and the enterprise revenue is increased.
