Abstract
The present invention relates to a method for inhibiting the fermentation of urban house refuse. Kiln dust generated in the process of cement production or raw material powder used for the cement production is added to urban house refuse or sorted kitchen remains according to a certain proportional requirement, and all the materials are stirred and harmoniously mixed by a stirrer. Adding amount changes along with different temperature, different seasons and different components of refuse, and an optimum adding range means that the ratio of urban house refuse to the kiln dust or the raw material powder used for the cement production is (5 to 10): 1. The method can effectively inhibit the fermentation of urban house refuse and extend the stacking time thereof, so the method solves the problems of easy putrefaction, odor and pollution in the process of piling urban house refuse. The method adopts the kiln dust generated in the process of cement production or the raw material powder used for the cement production as additive agents, and house refuse enters a cement producing system with the additive agents, and final products are cement clinkers. Refuse waste slag has no need of secondary treatment, and the cement raw material powder or the kiln dust can be produced without additionally increasing investments. The method changes refuse into resources at the time of making refuse treatment harmless.
Description
Technical field
What the present invention relates to is a kind of method of utilizing the cement production process inhibiting urban house refuse fermentation.Belong to urban garbage disposal technology field.
Technical background
The processing of domestic waste has become the topic that the whole society pays close attention to, utilizes the cement production process disposal of refuse, can accomplish real resource and innoxious.The main production raw material in cement plant is the cement slurry of alkalescence, and its output is very big, the new type nonaqueous cement factory of 5000t/d scale, and raw material output can reach about 8000t/d.The high temperature of manufacture of cement and alkaline operating mode are thoroughly cleared up Toxic, the generation of containment pernicious gas and the regeneration of noxious material.Final residue becomes the cement partial elements after the waste incineration, has formed clinker, does not need to carry out after-treatment again.Utilizing cement production process to handle in the process of domestic waste, the stacking problem of rubbish is a difficult point, and the rubbish ratio is easier to fermentation, produces foul gas and waste water, has a strong impact on and produces and living environment.
Summary of the invention
The objective of the invention is to problem, propose a kind of method of utilizing the kiln ash that produces in the new type nonaqueous cement factory production process or manufacture of cement with raw material powder inhibiting urban house refuse fermentation at above-mentioned existence.Technical solution of the present invention: according to adding kiln ash or the manufacture of cement raw material powder that produces in the cement production process in the kitchen excess of certain ratio after domestic waste or sorting, and stir, mix with mixer, addition changes with the difference of temperature, season, waste component, and suitable interpolation scope is a domestic waste: kiln ash or manufacture of cement raw material powder=5～10: 1.Rubbish fermentation mainly is because the bacterium decomposing organic matter becomes it into organic acid and alcohol, further resolves into gases such as methane at last again.Kiln ash and raw material have higher specific surface area, after adding in the domestic waste, can adsorb the moisture content in the rubbish, completely cut off between the rubbish and being in contact with one another between the bacterium, alkalescence has played the effect of kill bacteria simultaneously, has fundamentally contained the fermentation of rubbish.The main gas that rubbish fermentation produces is CH
4, be in the end the stage decompose organic acid by methane bacteria and produce, and kiln ash and raw material can be taken off the organic acid branch of earlier fermentation generation, avoid the formation of foul smell.The sewage that produces in the urban garbage disposal process is delivered to grinding machine and is evaporated, and the organic matter in the sewage of evaporation back enters firing system with raw material.
Good effect of the present invention: when utilizing New Type Dry-process Cement Production PROCESS FOR TREATMENT domestic waste, adopt the effectively fermentation of inhibiting urban house refuse of this method, prolong its pilling up time, solve perishable, smelly, pollution problem that domestic waste occurs in stacking process.Additive is kiln ash or the manufacture of cement raw material powder that produces in the cement production process, raw material or the output of kiln ash in the cement plant are very big, house refuse enters cement production system with it, final product is a clinker, the rubbish waste residue need not after-treatment, and the production of cement raw meal or kiln ash does not need to add in addition investment.When realizing that garbage disposal is innoxious, reach resource.
Embodiment 1, December 5
In 1 ton of domestic waste, add the kiln ash that produces in 0.1 ton of production process, and stir, mix with mixer.
Embodiment 2, December 5
In 0.7 ton of house refuse, add the kiln ash that produces in 0.1 ton of production process, and stir, mix with mixer.
Embodiment 3, December 5
In 0.5 ton of house refuse, add the kiln ash that produces in 0.1 ton of production process, and stir, mix with mixer.
Above-mentioned enforcement 1,2,3 has all obtained the effect of effective inhibiting urban house refuse fermentation.Prolong its pilling up time, solve perishable, smelly, pollution problem that domestic waste occurs in stacking process.
Claims (1)
1, a kind of method of inhibiting urban house refuse fermentation, it is characterized in that in domestic waste, adding kiln ash or the manufacture of cement raw material powder that produces in the cement production process, and stir, mix with mixer, add kiln ash or manufacture of cement raw material powder in domestic waste, its addition is a domestic waste: kiln ash or manufacture of cement raw material powder=5～10: 1.
