Embodiment 1

[0022] In the process of producing penicillin, a pharmaceutical company produces 8,900 tons of mycelium or / and fungal residue raw materials with a water content of 80% per year. In this embodiment, the mycelium and fungal residue are made into boiler biomass fuel. It should be noted that the present invention adopts the waste produced when the enterprise produces antibiotics. The waste can be mycelium or mycelia, or a mixture of mycelium and mycelium, and the mixing ratio of the two is not limited.

[0023] see figure 1 , is a schematic diagram of the preparation process and application process of the present invention.

[0024] The mycelia or / and the fungus residue raw material 1 are dehydrated, and the dehydration equipment 2 is a known equipment, such as a centrifugal dehydrator and a filter press dehydrator; in this example, a centrifugal dehydrator is used.

[0025] The dehydrated mycelium or / and bacterium slag 1 are dried, and the drying equipment 3 is a known equipment...

Embodiment 2

[0028] On the basis of Example 1, the mycelia or / and the fungus residue 1 are dehydrated, and the dehydration equipment 2 is a known equipment, such as a centrifugal dehydrator and a filter press dehydrator; this example adopts a centrifugal dehydrator.

[0029] The dehydrated mycelium or / and bacterium slag 1 are dried, and the drying equipment 3 is a known equipment. This example adopts a rotary drying furnace, and the heat of this rotary drying furnace utilizes a circulating fluidized bed coal-fired boiler to discharge The hot flue gas is used to dry the mycelium or / and the fungus residue 1 . Dehydration and drying to the moisture content of mycelium or / and bacterium slag 1 is less than or equal to 25% (percentage by weight), adds boiler fuel coal 5 and mixes, and the moisture content of the boiler biomass fuel that makes is less than or equal to 25% (percentage by weight) percentage). The amount of fuel coal added to the boiler is not strictly limited, and it only needs to...

Embodiment 3

[0031] The mycelia or / and fungal slag raw materials with a water content of 60% are added to boiler fuel coal and mixed to obtain boiler biomass fuel, wherein the amount of boiler fuel coal added is such that the water content of the boiler biomass fuel is less than or equal to 25%.

[0032] In order to further illustrate its application process of boiler biomass fuel prepared by the present invention, please combine figure 1 and figure 2 . figure 2 Shown is figure 1 The concrete example of the coal-fired boiler 8 in the present invention, the coal-fired boiler of the present invention is known equipment, can adopt chamber-fired boiler, circulating fluidized bed boiler, layer fired boiler etc., more ideally adopt circulating fluidized bed coal-fired boiler 11 .

[0033] The method of using the boiler biomass fuel 6 in the circulating fluidized bed coal-fired boiler 11 will be briefly described below. It should be noted that there is no strict limitation on the type of bo...

Abstract

The invention provides a boiler biomass fuel. Components of the fuel are mycelium or/and mushroom dregs, as well as 0 to 80 percent of boiler fuel coal. The weight percentage of moisture contained by the boiler biomass fuel is less than or equal to 25 percent. The preparation method comprises the step of mixing the mycelium or/and the mushroom dregs with the boiler fuel coal. The invention uses the mycelium and the mushroom dregs produced while enterprises produce penicillin, streptomycin, terramycin, tetracycline, lincomycin, gentamicin and kanamycin after simple treatment as boiler fuels, can avoid environmental pollution, and effectively utilizes heat value in the mycelium and the mushroom dregs.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to the treatment of mycelia and slag produced in the production process of antibiotics, in particular to a boiler biomass fuel made of mycelium or / and slag and coal. [0002] The present invention also relates to the preparation method of the boiler biomass fuel. Background technique [0003] In the process of producing penicillin, streptomycin, oxytetracycline, tetracycline, lincomycin, gentamycin, kanamycin and other antibiotics, pharmaceutical companies produce a large number of mycelia or / and bacteria residues. These mycelia, In the fungus residue, protein accounts for 30-50%, fat accounts for 0.6-5.5%, a small amount of antibiotics and other physiologically active substances remain, and it also contains a variety of amino acids and a large amount of water. [0004] At present, the treatment methods taken by pharmaceutical companies for the mycelia or / and bacteri...
