Harmless mushroom dreg treatment device with drying inactivation function and treatment method

Abstract

The invention discloses a harmless mushroom dreg treatment device with a drying inactivation function and a treatment method. According to an existing incineration method for treating antibiotic mushroom dregs, a large amount of mushroom dregs can be treated in a short time, extra fuel needs to be added in the combustion process for the mushroom dregs with a large water content, and therefore energy consumption and cost are high. The harmless mushroom dreg treatment device comprises a mushroom dreg bin (1), a venturi gas-powder mixer (3) is mounted at the top of the mushroom dreg bin, an inlet of the venturi gas-powder mixer is connected with a quicklime powder bin (4) and a Roots blower (2), an outlet of the mushroom dreg bin is connected with an inlet of a high-pressure dehydrator (5), an outlet of the high-pressure dehydrator is connected with an inlet of a crusher (6), and an outlet of the crusher is connected with an inlet of a conveyor (7). An outlet of the conveyor is formed in the top of a mushroom dreg dry powder bin (8), a discharging pipe is installed at the bottom of the mushroom dreg dry powder bin and connected with an inlet of an incinerator (9), and an outlet of the incinerator is connected with an inlet of a waste heat boiler (10). The harmless mushroom dreg treatment device with the drying inactivation function is provided.

Description

technical field [0001] The invention relates to the technical field of hazardous waste disposal, in particular to a device and a treatment method for harmless treatment of fungus residue with drying and inactivation functions. Background technique [0002] With the development of China's social economy, the amount of hazardous waste produced in the process of urban development has increased year by year. How to properly dispose of solid waste has become an urgent problem in the process of social development. The bacterial residue produced by the antibiotic pharmaceutical industry is a typical example. Hazardous waste, according to relevant statistics, a medium-scale antibiotic factory, with an annual output of about 60,000 tons of fungal residue, and the annual discharge of fungal residue in my country has already exceeded 1 million tons; [0003] At present, in the existing technology, pharmaceutical factories use conventional incineration methods to treat antibiotic residue...

Problems solved by technology

[0003] At present, in the existing technology, pharmaceutical factories use conventional incineration methods to treat antibiotic residues. This method can process a large amount of residues in a short time, and the volume reduction rate can reach 95%, eliminating drug residues such as antibiotics in the residues. , this method has many disadvantages, such as the difficulty of treating the bacteria residue with high water content, and the need to add additional fuel in the combustion process, resulting in high energy consumption and cost; the bacteria residue is processed by landfill technology, that is, the antibiotic residue Sent to a hazardous waste safe landfill for safe landfilling, however, safe landfill is a disposal method that places or stores hazardous waste in soil, and is more suitable for disposal of hazardous waste that cannot recover active ingredients or energy, for moisture Compared with antibiotic residues with a relatively high content of various organic matter, direct and safe landfill not only requires a large area and high disposal costs, but also produces secondary pollution and serious waste of precious resources;

[0004] In addition, the organic matter content of the antibiotic residue is about 90% on a dry basis, so anaerobic fermentation technology can also be used to recover biogas and prepare organic fertilizers. The difficulty of this technology is that the antibiotics remaining in the bacteria residue may also inhibit the anaerobic fermentation strains , resulting in a reduction in biogas production. At the same time, when the biogas residue and biogas slurry produced by anaerobic digestion are used as agricultural fertilizers, their biosafety still needs to be evaluated, which further limits the promotion of anaerobic fermentation technology for fungal residues; With the rapid development of industry, more than one million tons of antibiotic residues are produced every year. At present, there is no safe and effective treatment method. Therefore, it is urgent to develop a treatment technology with high treatment efficiency, large treatment capacity, low cost and environmental protection.
