Kitchen garbage fermentable treatment device and treatment method

Abstract

The invention relates to the technical field of garbage treatment, and discloses a kitchen garbage fermentable treatment device. The kitchen garbage fermentable treatment device comprises a fermentation tank, a feeder, a temperature and PH value detector, a one-way valve, a biogas storage device and a deodorization device. Biogas generated by fermenting kitchen garbage is accumulated in the fermentation tank, then ascends, and then pushes a rotating impeller, so power is transmitted to the stirring impeller through a transmission device; the stirring impeller is enabled to stir the kitchen garbage at a certain speed in the fermentation tank, so the spreading and heating uniformity of the biogas in the fermentation tank is improved, and meanwhile, the emission and ascending rate of the biogas is increased; and thus, a biogas collection speed is accelerated, and the decomposition rate of the kitchen garbage is increased. Hot water in a sterilization tank is introduced into the fermentation tank to heat the fermentation tank and keep an optimal reaction temperature, so the decomposition rate is further increased, and decomposition time is shortened; and thus, kitchen garbage treatmentefficiency is further improved, the utilization rate of biogas is increased, the consumption of external energy sources is reduced, and garbage treatment cost is lowered.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a device and method for fermentable treatment of kitchen waste. Background technique [0002] Kitchen waste refers to the kitchen waste generated by residents in the process of daily life and food processing, catering services, and unit meals. Kitchen waste includes discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, and packaging materials. Etc., because kitchen waste is easy to ferment, deteriorate, and rot, it not only produces a large amount of toxins and emits odor, but also pollutes water bodies and the atmosphere when accumulated on the surface, and breeds harmful bacteria. Therefore, if kitchen waste is not disposed of in time, it will not only affect a The city's appearance and environmental sanitation, but also the spread of diseases, endangering human daily life and physical and mental health. Kitchen waste contains a lot of biomass ener...

Problems solved by technology

[0003] Usually, in order to speed up the fermentation of food waste, it is necessary to stir the food waste in the fermentation tank, and the stirring device needs to be driven by an external motor, which increases energy consumption and processing costs. The generated biogas heats the fermenter. Although the consumption of other energy sources can be reduced to a certain extent, the utilization of biogas combustion energy is not sufficient, resulting in a low utilization rate of biogas.
