Equipment and method for producing industrial pure hydrogen by utilizing antibiotic fermentation waste residues

Abstract

The invention relates to equipment for producing industrial pure hydrogen by utilizing antibiotic fermentation waste residues, which comprises a preparation tank 3, a pre-treatment tank 5, a buffer tank 6, a ball mill 8, a gasification furnace 9, a transformation tower 11, a desulfurization tower 12, a decarburization tower 13, a hydrogen extraction tower 14 and a plurality of pumps 15. A method for producing the industrial pure hydrogen by utilizing the antibiotic fermentation waste residues comprises the following steps: alkalifying the antibiotic fermentation waste residues, regulating the PH value to 9.0, then entering the wet ball mill or a rod mill, mixing with coal and pulping, and producing coal water slurry to be pumped into a coal water slurry intermediate storage tank; and mainly using Shenhua coal to prepare coal water slurry, pulping the coal water slurry by a slurry pump to the gasification furnace to enable the coal water slurry to react with pure oxygen to generate water gas, wherein the temperature in the gasification furnace is 1300-1350 DEG C, the retention time is 10 seconds, and the pressure is 1.3 MPa, decomposing the water gas into CO, H2, CO2, CH4 and other matters, and producing the industrial pure hydrogen through the processes of transformation, desulfurization, decarburization and the like. The equipment and the method have the benefits that the environment can not be polluted, and the waste residues can be transformed into the industrial pure hydrogen.

Description

technical field [0001] The invention relates to a device and method for producing industrially pure hydrogen by utilizing antibiotic fermentation waste residue. Background technique [0002] As we all know, pharmaceutical companies produce a large amount of solid waste. Among them, the mycelium residue and waste activated carbon produced by antibiotic fermentation are hazardous wastes because they contain a certain amount of antibiotics. It is a difficult problem for environmental protection. How to dispose of these hazardous wastes and turn them into treasures , is a major issue in the environmental protection industry. [0003] At present, the antibiotic fermentation waste produced by pharmaceutical companies is generally treated by incineration technology. Although incineration can decompose a large amount of harmful waste and convert it into harmless substances, this method requires a large investment, and it is easy to cause secondary pollution during the incineration ...
