Description

Kitchen waste pulping, smashing and filtering all-in-one machine

Technical Field

The utility model relates to a refuse treatment equipment, a kitchen garbage mortar crushing filters all-in-one specifically says so.

Background

The recycling treatment of the kitchen waste plays a crucial role in the environment development, and the pollution of solid waste organic matters can be greatly reduced. Biogas generated after anaerobic fermentation and degradation of the kitchen waste can be converted into electric energy and heat energy through a cogeneration generator set, the electric energy can be connected into a power grid for production and living to be practical, the heat energy can supplement partial heat energy requirements of municipal heating facilities after being supplied to the waste treatment equipment for use, and the situation that economic benefits and social benefits win together is realized. The biogas slurry generated after fermentation can be widely used as liquid organic fertilizer in the fields of agricultural irrigation, garden planting and the like after denitrification, desalination and desulfurization treatment.

The current situation of kitchen waste disposal lies in that the waste is solid waste formed in the process of domestic consumption of residents. In recent years, with the improvement of living standard of people, the generation amount of kitchen waste tends to increase. The daily kitchen waste production in China exceeds 2 million tons, the daily kitchen waste production in Shanghai city is 1200 tons, and the daily kitchen waste production in Beijing is 1600 tons. At present, the main disposal mode of kitchen waste in China is as follows: farmers or individual transporters in suburbs of cities recycle through large catering business spots and then transport the products to suburbs of small-sized farms for feeding livestock; most of the kitchen waste generated by common residents is mixed with household waste for landfill disposal. Both of these methods are environmentally damaging. When the livestock is fed by the kitchen waste, bacteria in the kitchen waste can be infected to the livestock, the livestock can be eaten by people on a dining table, and people at the top end of a food chain can be infected with diseases. The kitchen waste which is not collected in a classified manner is directly buried, and due to high organic components, the kitchen waste has large impact load on a landfill site, so that underground and surface water bodies are polluted to form a germ-breeding land. If a reasonable treatment method cannot be found for such huge amount of kitchen waste, not only is waste of resources but also pollution to the environment is caused, so that reasonable treatment and utilization of the kitchen waste are very important.

The current resource situation of kitchen waste is one of the contents of urban waste management, and the influence on urban economy, society, ecological environment and normal life of residents is increasing. Therefore, city managers and many experts and technologists in various countries around the world are always looking for the way of kitchen waste. After many years of efforts, people realize the concentrated treatment of the kitchen waste, and the method is favorable for realizing the re-utilization and the maximum recovery of the flying kitchen waste, namely the recycling of the kitchen waste. At present, the current situation of recycling kitchen waste is serious, and the harm of foreign kitchen waste is far less serious than that of China, so that the kitchen waste can be attributed to different dietary structures and management systems. China has developed catering industry, consumers have a dinner gathering habit, and a large amount of food waste is easily caused by a special dining table culture. The introduction of the Aries sea is that in the aspect of treatment aiming at the existing garbage, foreign countries are mostly formed 'who pollutes who pays' modes, the measure promotes source decrement, and the treatment cost collected from the source can be used for subsidizing the operating profit of the kitchen garbage disposal plant. Therefore, the development trend of treatment technology is generally 'reduction and harmlessness' in foreign countries, and the aim of eliminating garbage is achieved. The pollution discharge main body in China, namely the catering industry, has already formed a rule of collecting money for garbage collection personnel, and the kitchen garbage disposal cost is difficult to be pushed in a short period due to the difference of one inlet and one outlet. The shortage of the expenditure requires that the kitchen treatment mode of China is advanced to 'resource' and the kitchen waste is transported into a treatment plant, so that profitable products are produced to maintain the continuous operation of the treatment plant.

The kitchen waste recycling treatment has distinct characteristics, and the required treatment method is different from the household waste. It is known that in recent years, the components of kitchen waste are also changing: wherein the protein and fat content is continuously rising. The increase of the waste oil and fat has adverse effect on the subsequent biological treatment, so that the oil removing strength needs to be increased in the pretreatment. In the kitchen waste treatment process, because the treatment process is different from the target product, the production lines also have various advantages and disadvantages and places needing attention. The currently applied technologies mainly include: anaerobic fermentation technology, aerobic composting technology, high-temperature aerobic fermentation technology, wet and hot biological treatment complete technology and the like. The anaerobic fermentation technology is a widely recognized mainstream technology, realizes the recycling of garbage, accords with the national energy policy, and has the advantages of low operation cost, capability of keeping kitchen waste away from a food chain and the like. However, the process occupies a large area, has high investment and long starting time, the outlet of the biogas needs to face the barrier problem of the energy industry, the reduction is not obvious, and the biogas slurry and the biogas residues still need to be treated; the aerobic composting technology is more mature, the process cost is low, the operation is simple and easy to control, but the defects of incomplete sterilization, non-ideal treatment effect, large occupied area, long period and the like exist; the high-temperature aerobic fermentation technology has the advantages of thorough sterilization, high product quality, good sanitary condition of treatment places, suitability for scattered on-site treatment and the like, but the operation problems of excessive auxiliary material addition, difficulty in large-scale production, high energy consumption and the like need to be considered; the complete technology of the moist heat biological treatment has the highest resource degree, and the process has high product value, small occupied area and low investment.

So at present kitchen garbage is widely used for fertilizer processing, but at the in-process discovery of processing, kitchen garbage water content is great, and it is bigger to smash back water content, and present kitchen garbage treatment facility can not make the water in the kitchen garbage well obtain effective separation, and kibbling processing residue water content is higher, is unfavorable for fertilizer processing.
