Household garbage closed-loop tunnel type harmless treatment center and method

Abstract

The invention discloses a household garbage closed-loop tunnel type harmless treatment center and method, and relates to the technical field of garbage treatment. The treatment center comprises an outer wall, an inner wall and a closed-loop tunnel; the front portion of the closed-loop tunnel is a low-position operation area, and the rear portion of the closed-loop tunnel is a high-position operation area; a garbage combustion mine car system is arranged in the closed-loop tunnel, so that transportation and incineration of household garbage in the treatment center are facilitated; and a plurality of flue gas purifiers are also included, are arranged in the inner wall and are used for purifying flue gas generated by garbage incineration. The invention further discloses the household garbage closed-loop tunnel type harmless treatment method which is applied to the treatment center. A garbage incineration area is arranged in the high-position operation area of the closed-loop tunnel, it is guaranteed that the flue gas generated by incineration cannot diffuse to the whole closed-loop tunnel, the treatment center is mostly arranged below the ground surface, and therefore the occupied area is small; and meanwhile, compared with the prior art, a pulverizer does not need to be additionally arranged for treating the garbage, and cost is effectively saved.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a closed-loop tunnel-type harmless treatment center and method for domestic garbage. Background technique [0002] Household garbage refers to solid waste generated in daily life or activities that provide services for daily life and solid waste that is regarded as domestic garbage according to laws and administrative regulations. With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, urban domestic waste has also increased in large quantities, making it more and more difficult to dispose of waste. The resulting environmental pollution and other problems have gradually aroused the widespread attention. [0003] In the prior art, domestic garbage is mainly disposed of by landfill and incineration. However, there are problems in landfill treatment, such as large-scale...

AI Technical Summary

Problems solved by technology

However, there are problems in landfill treatment, such as large-scale investment in landfill construction, large area, difficult site selection, and water pollution by waste seepage.

However, waste incineration power plants have become an explosive trend, but waste incineration power plants also have problems of huge investment, long construction period, and difficult site selection for NIMBY

In addition, financial subsidies for electricity prices are required to maintain operation. The tonnage of waste to be processed is expensive, and the amount of waste must be concentrated in large and medium-sized cities to meet 300 tons per day, which is severely restricted by region.

The majority of small and medium-sized towns must spend a lot of money to compress, transfer and sort many times, and the workload is relatively large

[0004]There are also small-scale waste incinerators developed all over the country, which have high costs, difficulty in meeting environmental protection standards, small daily processing capacity, manual operation and harsh environment and many other disadvantages
