Description

TECHNICAL FIELD

[0001] The utility model relates to oil water separation technical field, concretely relates to a novel kitchen garbage biological decomposition and oil water separation device. BACKGROUND

[0002] The existing kitchen garbage treatment is divided into two situations of front-end small-scale equipment on-site treatment and rear-end centralized treatment.

[0003] The front-end on-site treatment small-scale equipment usually adopts two kinds of equipment of crushing direct discharge and crushing dehydration, and the use of the two kinds of equipment will lead to a large amount of particulate matter and a large amount of oil discharged into the sewage pipe network, and the two situations of particulate matter deposition and pipeline deposition and oil adhesion to the pipe wall leading to the continuous reduction of the pipe diameter, which not only causes great damage to the sewage pipe network, but also leads to the waste of a large amount of oil with high economic value in the kitchen garbage.

[0004] In addition, a small amount of crushing dehydration oil water separation all-in-one machine in the market also has the problems of low oil collection rate and high residue and oil content in wastewater, and also has the problems of oil waste and pipeline damage.

[0005] The rear-end centralized treatment refers to the unified collection and transportation of kitchen garbage to the rear end for treatment, and the common treatment methods at present are centralized landfill, centralized incineration, centralized aerobic and anaerobic treatment, aerobic composting and steam drying for feed.

[0006] The centralized landfill treatment refers to the direct entry of a large amount of kitchen garbage into the landfill site without treatment, which will bring the following problems and hidden dangers to the landfill site. On the one hand, due to the high oil content and high water content of kitchen garbage, the high-fat water in the landfill operation will block the gravel drainage layer, cause internal percolate drainage, increase the free water head of the landfill site impermeable layer, increase the possibility of percolate leakage, and extremely likely cause serious events such as groundwater and soil pollution; on the other hand, compared with household garbage, the kitchen garbage has extremely high anaerobic digestion gas production, and the generated biogas is accumulated inside, which will suddenly rush out when reaching the critical point, mix with the external air, and cause the sudden increase of methane concentration. If the overlying soil layer of the garbage or the filling depth is increased, the air permeability will be more affected, the accumulated methane in the garbage pile will increase rapidly, and it is extremely likely to reach the explosion limit, thereby causing the explosion of the landfill site and causing serious safety accidents. This method also leads to the waste of a large amount of kitchen waste oil with high economic value.

[0007] Centralized incineration refers to the government's unified collection and transportation to the garbage incineration power plant for incineration. Due to the difference between kitchen waste and household garbage, the water content of kitchen waste is usually about 90%, and its heat value is very low, which requires a large amount of kerosene for combustion, resulting in high incineration cost, and is also easy to cause the production of dioxin, an organic compound and heavy metal, in the incineration process due to insufficient incineration temperature; like landfill, this processing method also leads to the waste of a large amount of kitchen waste oil with high economic value.

[0008] Centralized aerobic treatment refers to a technical solution that first separates the kitchen waste into oil, water and residue, collects part of the animal and vegetable oil in the kitchen waste, and then processes the residue through high-temperature biological fermentation to convert the organic matter in the kitchen waste into organic fertilizer. However, this solution has four major shortcomings: 1. The oil recovery rate is not high; 2. The high-temperature steam required for oil-water-residue three-phase separation has high energy consumption; 3. The high-temperature biological fermentation process has extremely high power consumption, usually requiring 150 degrees of power consumption per ton, which is extremely high in cost and not environmentally friendly; 4. The high oil and residue content in the wastewater makes it difficult to treat, resulting in a wastewater treatment cost of over 100 yuan / ton; in short, the process is complex, the benefits are low, the cost is high, and it needs to rely on government subsidies and is difficult to generate economic benefits.

[0009] Centralized anaerobic treatment refers to a technical solution that first separates the kitchen waste into oil, water and residue, collects part of the animal and vegetable oil in the kitchen waste, and then puts the residue into a high-intensity treatment tank for anaerobic treatment to convert the residue into combustible biogas and a small amount of residue. However, this solution also has five major shortcomings: 1. The oil recovery rate is not high; 2. The high oil and residue content in the wastewater makes it difficult to treat, resulting in a wastewater treatment cost of over 100 yuan / ton; 3. The anaerobic treatment cycle is extremely long, with an average of more than 30 days per cycle, and the efficiency is low; 4. The required site is huge and the equipment investment is huge; 5. The waste residue and biogas produced during the treatment process are difficult to treat and have high treatment cost; therefore, this solution also has the shortcomings of low benefits, high cost, and reliance on government subsidies and difficulty in generating economic benefits.

[0010] Although aerobic composting can convert waste into high-quality fertilizer for application to farmland, due to the characteristics of kitchen waste itself, there are few successful cases of directly aerobic fermentation treatment of kitchen waste, especially in large-scale treatment plants, mainly due to the constraints of fertilizer market demand and its seasonal fluctuations, the end product of aerobic composting faces the problem of difficulty in finding a way out of the fertilizer market, at the same time, the moisture content of kitchen waste is usually more than 80%, high-moisture kitchen waste is prone to fill the entire space of the pile during aerobic fermentation, causing microorganisms to be in an anaerobic fermentation state, thereby slowing down the degradation rate and producing hydrogen sulfide and other odors, which seriously affect the aerobic fermentation process; while kitchen waste contains a large amount of oil and salt, which also restricts the life activity of microorganisms, resulting in a prolonged fermentation process and a decrease in the quality of the fermentation product, and even the final output contains excessive salt and cannot be used, and further incineration treatment is required;

[0011] As for the method of finally steaming kitchen waste to make feed, although this process has the characteristics of high mechanization, few equipment, and small investment, but high-temperature cooking can only kill harmful bacteria in kitchen waste, but cannot "denature" animal protein, and the hidden danger of "homologous effect" still exists, and a large amount of odor is discharged during the treatment process, causing serious air pollution.

[0012] Therefore, the current domestic kitchen waste treatment industry needs a new type of equipment with low procurement and use cost, high waste oil recovery rate, and simple operation. Practical new type
