Description

Kitchen waste heating, filtering and treating device and method

Technical Field

The invention relates to the technical field of kitchen waste treatment, in particular to a kitchen waste heating, filtering and treating device and a kitchen waste heating, filtering and treating method.

Background

In recent years, along with the rapid development of economy and society and the acceleration of urban process, restaurant enterprises rapidly develop, the yield of kitchen waste is rapidly increased, while due to the light and thin conventional management consciousness and lack of corresponding treatment facilities, a large amount of untreated kitchen waste and swill-cooked waste oil flow into society through various ways, thereby not only influencing urban environmental sanitation, but also bringing serious hidden danger to food sanitation safety of people, and at present, the kitchen waste mainly has the following paths that firstly, the kitchen waste is intensively transported to a household waste landfill for landfill treatment; secondly, burning after centralization; thirdly, after unified collection, carrying out aerobic composting by utilizing an aerobic reaction; fourth, anaerobic fermentation is carried out; fifthly, evaporating to dryness after collection to be used as feed.

However, due to the lack of enough kitchen waste treatment facilities, a large amount of kitchen waste is directly fed into a household garbage landfill without being treated, the landfill is subjected to the following problems and hidden dangers, on one hand, due to the extremely high oil content and water content of the kitchen waste, high-fat water in the landfill operation can block a broken stone diversion layer, so that the internal percolate is not smoothly led out, the free water head of an impermeable layer of the landfill is increased, the possibility of percolate leakage is increased, and serious events such as groundwater pollution are extremely likely to occur; on the other hand, compared with household garbage, the anaerobic digestion gas production rate of the kitchen garbage is extremely high, generated methane is accumulated in the kitchen garbage and suddenly rushed out when reaching the critical point of the kitchen garbage, the methane is mixed with the external air to ensure that the methane concentration is suddenly increased, if the covering soil layer or the landfill depth of the garbage is increased, the gas permeability is more influenced, the accumulated methane in the garbage accumulation is rapidly increased, the explosion limit of the garbage is most likely to be reached, thereby causing the explosion of the landfill site and causing serious safety accidents, and the water content of the kitchen garbage is usually about 90 percent due to the fact that the kitchen garbage is different from the household garbage in incineration, and the heat value of the kitchen garbage is extremely low, so the kitchen garbage is not suitable for incineration treatment; although the aerobic composting can convert garbage into high-quality fertilizer to be applied to farmlands, due to the characteristics of kitchen garbage, the kitchen garbage is directly subjected to aerobic fermentation treatment at home and abroad, particularly, large-scale treatment plants 2 are fewer in successful operation cases, mainly due to the limitation of fertilizer market demands and seasonal fluctuation thereof, the problem that the finished product of the aerobic composting is difficult to go out of the way is mainly solved, meanwhile, the water content of the kitchen garbage is usually more than 80%, the kitchen garbage with high water content is easy to fall and fill the whole stacking space in the aerobic fermentation process, so that microorganisms are in an anaerobic fermentation state, the degradation speed is reduced, odor such as hydrogen sulfide is generated, and the aerobic fermentation process is seriously influenced; the kitchen waste contains a large amount of oil and salt, the life activity of microorganisms is restricted, the period of the fermentation process is prolonged, the quality of a fermentation product is reduced, the anaerobic fermentation mode is to utilize methane generated by anaerobic decomposition to generate electricity, the resource utilization of the kitchen waste is realized, however, the process has extremely high equipment requirements, especially strict requirements on the front-end sorting process, certain scale of the kitchen waste is ensured, the scale benefit can be realized, the treatment cost is reduced, complicated and numerous equipment makes the early investment of the kitchen waste huge, the treatment difficulty of waste residues and biogas slurry generated in the treatment process is high, the treatment cost is high, and the method of finally evaporating the kitchen waste residues and biogas slurry to prepare the feed has the characteristics of high mechanization degree, less equipment and small investment, but the hidden danger of animal protein denaturation and homology effect still exists because the harmful bacteria in the kitchen waste can be killed by high-temperature digestion, the problem of genetic variation exists for a long term, in addition, the nutrition component of the final product of the process can not meet the nutrition requirements of the livestock at different stages, and the process is not accepted by the protein and is a serious odor and polluted by the dry and wet water in the field .

The invention provides a kitchen waste heating, filtering and treating device and a kitchen waste heating, filtering and treating method aiming at various conditions.
