Problems solved by technology

But incineration creates new problems: air pollution, heavy metal pollution, dioxin pollution, etc.
It not only solves the way out of garbage, but also achieves the purpose of recycling. However, the amount of domestic garbage compost is large and the nutrient content is low. Long-term use will easily cause soil compaction and groundwater quality to deteriorate. In addition, urban garbage in my country is collected in a mixed manner, which contains plastics. There are quite a lot of non-compostable materials such as glass, metal, etc. Therefore, in the early stage of adopting this method, the collected garbage has to be specially classified to screen out non-compostable materials such as plastic, glass, metal, etc. Therefore, the use of this method The waste disposal method has low efficiency and low yield, which leads to poor waste reduction effect
[0009] As mentioned above, the above-mentioned various garbage disposal methods are not suitable for the development theme of energy saving and environmental protection in my country's current and future society due to the various shortcomings. Garbage treatment technology that is non-toxic, harmless, and can also make rational use of garbage is imperative

Embodiment Construction

[0042] Such as Figures 1 to 5 Shown: a pretreatment method before domestic waste incineration for power generation, which includes the following steps:

[0043] Such as figure 1 , 2 Shown: the first step, the domestic waste crushing and dehydration stage;

[0044] First, the domestic garbage A is transported to the unloading hall 10 by the garbage truck C, then the domestic garbage A is dumped into the garbage treatment workshop 20, and the domestic garbage A is crushed and magnetized in the garbage treatment workshop 20. selection and dehydration.

[0045] Wherein, the entrance of this unloading hall 10 is provided with damper 11, and this damper 11 works and produces wind wall, and then the smell in this unloading hall 10 can not be distributed to this unloading hall 10 outside, this unloading hall 10 and The garbage processing workshop 20 is connected, and between the unloading hall 10 and the garbage processing workshop 20, a discharge hall curtain sealing machine 12 ...

Abstract

A pretreatment method before power generating by incinerating municipal solid waste is used for processing the municipal solid waste into nontoxic incinerating matter and comprises the following steps of: firstly crushing and dehydrating the municipal solid waste, subsequently drying the municipal solid waste and treating the tail gas, and finally preparing a nontoxic incinerating matter by mixing the municipal solid waste with a certain proportion. After the pretreatment method is adopted, a large amount of municipal solid waste can be treated as nontoxic incinerating matter, the pollution of the municipal solid waste to the environment is reduced, the inconvenience of daily municipal solid waste treatment is also reduced, the space needed when the municipal solid waste is treated is reduced further and the defect that the piling of municipal solid waste causes pollution to the environment is solved excellently; furthermore, the pollution of the municipal solid waste to the environment is reduced, simultaneously, the municipal solid waste is prepared to the combustibles used for incineration power generation and the consumption of the resource is saved.

Description

technical field [0001] The invention relates to a garbage treatment method, in particular to a household garbage incineration that firstly crushes household garbage and dehydrates it, then dries the household garbage and treats the exhaust gas, and finally makes the household garbage into non-toxic incinerators. Pretreatment method before power generation. Background technique [0002] Garbage is solid waste generated in human daily life and production. Due to the large amount of discharge and complex and diverse components, it brings difficulties to treatment and utilization. If it cannot be disposed of in time or improperly disposed of, it will pollute the environment and affect environmental sanitation. Garbage disposal is to quickly remove garbage, and conduct harmless treatment, and finally make reasonable use of it. [0003] With the acceleration of urbanization in our country, environmental issues are gradually being paid attention to, energy saving and environmental...
