Mixed carbonization treatment method of plant fiber and sludge in garbage undersize

Abstract

The invention discloses a mixed carbonization treatment method of plant fiber and sludge in garbage undersize, which comprises multi-stage fine sorting, plant fiber crushing in undersize, mixing of plant fiber powder and sludge in proportion, and plant fiber The four-step process of carbonization treatment of the mixture with sludge makes domestic garbage and sludge into biomass combustible charcoal, which solves various shortcomings in the traditional technology of garbage undersize treatment. Its remarkable effects are: fast dehydration speed, reduced particle carbonization ash powder, stable particle formation, uniform tar removal, fast fiber carbonization speed, and small calorific value loss; thus completely realizing the recycling of waste and the realization of domestic waste. recycling and harmless disposal.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment of urban garbage, in particular to a mixed carbonization treatment method of plant fibers and sludge in garbage undersize. Background technique [0002] With the rapid development of my country's economy and industrialization, the scale of cities continues to expand, and the total amount of municipal solid waste is increasing day by day. Most counties and prefecture-level cities in my country are currently suffering from the inability to effectively dispose of domestic waste. Waste disposal has become a huge challenge for China's sustainable development. [0003] At present, there are two mainstream methods for the treatment of garbage and its undersize in various countries in the world: incineration method and landfill method, and auxiliary methods include high-temperature composting method and RDF derived fuel method. However, there are various deficiencies in the abo...

AI Technical Summary

Problems solved by technology

[0007] ① There is no pre-classification and sterilization and harmless treatment, and a large number of hidden dangers such as bacteria, viruses, and heavy metal pollution have not been eradicated; ② Garbage is piled up for a long time, and the seepage will pollute groundwater resources for a long time. This method is potentially harmful

③It will bring endless troubles

②Long fermentation treatment cycle and large floor area

③ Unable to remove sulfate ions, etc., causing soil compaction and polluting the land. ④ Volatile hydrogen sulfide produced during fermentation will pollute the atmosphere, especially some heavy metal elements in fertilizers will be enriched in the soil and enter the human body with the food chain, seriously endangering human beings good health

②After pyrolysis, a large amount of residue is produced, which brings the problem of secondary pollution of organic alkanes

Not only did it fail to meet people's requirements in terms of harmlessness, but also in terms of resource utilization, it did not tap potential huge resources to achieve resource recycling and bring more negative impacts on the environment
