Preparation method of synthesizing biomass formed fuel by using pharmaceutical mushroom dregs

Abstract

The invention relates to a preparation method of synthesizing a biomass formed fuel by using pharmaceutical mushroom dregs. Antibiotic mushroom dregs are prepared into the biomass formed fuel by a raw material crushing and screening unit, a prilling and molding unit, and a conveying and air-drying unit. By making full use of the characteristics of the mushroom dregs that the content of organic matters is high (greater than 90%) and the heat value is high (3600-4000Kcal / kg, the water content is less than or equal to 20%), the mushroom dregs are compressed and molded to obtain the biomass fuel. Through the process, wastes (mushroom dregs) which are low in energy density are compressed to granular or bulky fuels which are large in specific gravity and hard in texture. The product processed by the steps has the characteristics of being easily on fire, low in ash content, clean and sanitary and the like, and the product meets the technical requirements of national biomass solid formed fuel so as to be further used as a raw material for a biomass power generation plant to replace part of straws for incineration power generation and heating, so that harmless treatment and resource utilization are realized and the fuel cost of a production enterprise is lowered.

Description

technical field [0001] The invention relates to a preparation method for synthesizing biomass briquette fuel by using pharmaceutical fungus residue. Background technique [0002] Since 2008, according to the requirements of the "Pharmaceutical Industry Pollution Prevention and Control Technology Policy", the mycelium waste generated in the pharmaceutical production process is included in the hazardous waste management and must be incinerated or safely landfilled. Antibiotic residues are also clearly listed in the list of hazardous waste and treated as hazardous waste. Bacterial residues are incinerated as hazardous waste, and special incinerators are required. According to preliminary estimates, the cost of waste residue treatment per ton is about 2,000 yuan. In Shijiazhuang alone, hundreds of thousands of tons of fungal residue are produced every year. Even if calculated on the basis of 300,000 tons a year, the processing cost is as high as 600 million yuan. [0003] The...

Problems solved by technology

The existing incineration treatment method is unacceptable to the enterprise in terms of cost. If it is processed in this way, the treatment cost will exceed its profit level, resulting in high production costs, which ultimately makes it difficult to implement this method in practice.

[0004] If all the fungal residues are incinerated, according to the above conservative estimate, the annual production in Shijiazhuang City is 300,000 tons, and the corresponding incineration disposal facilities are required to have a capacity of 300,000 tons. According to statistics, the current compliance incineration disposal units in Shijiazhuang City The incineration disposal capacity is less than 50,000 tons, and the gap in incineration disposal facilities is obvious, which also makes it difficult to implement this method

[0006] The content of organic matter such as protein in antibiotic bacteria residue (dry basis) is as high as 90%, which is a relatively good renewable resource raw material. It is a great waste of resources to achieve the purpose of harmlessness only through simple incineration.
