Description

Negative pressure type plasma odor and wet garbage temporary storage box taking solar energy as energy source

Technical Field

The invention belongs to the field of household garbage transfer, and particularly relates to a negative pressure type plasma odor and wet garbage digestion temporary storage box taking solar energy as energy.

Background

The garbage classification is an important link and a key field of ecological civilization construction, and is an important gripper of ecological civilization (the environmental economic research center of the university of double denier, the assistant principal and the subordinate principal Lixieqing, the strength of the garbage classification witness system [ N ]. the China environmental newspaper, 2019-11-15 (003)). In recent years, China accelerates the implementation of a garbage classification system, the national garbage classification work is started from point to surface, the effect is shown, 46 key cities try first, and the garbage classification is promoted to make positive progress. In 2019, the domestic garbage classification work is started comprehensively in cities on the national level and above, 46 key cities from 2020 bottom will be built into the garbage classification treatment system basically, and cities on the national level and above before 2025 bottom will be built into the garbage classification treatment system basically.

The implementation of garbage classification is not only a policy requirement, but also an urgent requirement of people on a beautiful living environment. Generally, domestic waste implements the "four classification" criterion: harmful garbage, recoverable matters, wet garbage and dry garbage. Harmful garbage: the waste lamp tube is a domestic waste which causes direct or potential harm to human health or natural environment, such as waste batteries, waste lamp tubes, waste medicines, waste paint and containers thereof. Recyclable materials: the waste paper is a domestic waste which is suitable for recycling and reusing, such as waste paper, waste plastics, waste glass products, waste metal, waste fabrics and the like. Wet garbage: namely perishable garbage, which refers to perishable biomass domestic wastes such as food material waste, leftovers, overdue food, melon peel and fruit stones, green plants of flowers, traditional Chinese medicine dregs and the like. Drying the garbage: that is, other garbage means other domestic waste except recyclable materials, harmful garbage and wet garbage. The temporary storage and transportation process of various wastes has many problems, wherein the temporary storage problem of wet wastes is particularly obvious, the wet wastes are very easy to decay and rot, generate odors which are difficult to bear by people, and are particularly easy to breed mosquitoes and flies. In the high temperature state in summer, the odor and nausea degree in the process of house refuse decay are further aggravated under the combined action of a large number of microorganisms, mosquitoes and flies and small animals, so that diseases are spread, health is damaged, and the living environment is also worsened (invar and excitement. conquer the difficulty of classification and disposal of wet refuse [ N ] in China environmental report, 2019-09-05 (005)). Therefore, the odor of the wet garbage is simply and effectively treated, and the dissipation of odor substances of the wet garbage is reduced. The method has positive effects of improving the enthusiasm of people classification and reducing bad experiences of residents in the garbage classification process.

At present, a plurality of odor decomposition technologies are available, and among them, the technologies widely used include adsorption technology, condensation technology, thermal oxidation technology, catalytic oxidation technology, plasma technology, and the like. Due to the limitations of a single technology, a process of combining multiple technologies is widely used in industry, wherein the plasma catalysis combination technology is proved to have outstanding effects in odor treatment (chuyinlong, liushifeng, guyanpeng, wangjian.
