Description

Technical Field

[0001] The patent of this invention belongs to comprehensive treatment equipment for food waste, specifically to a device for treating food waste by a fermentation and decomposition method, and belongs to the field of environmental protection. Background Art

[0002] With the rapid development of my country's economy, the improvement of people's living standards and the acceleration of urbanization, the amount of urban garbage is also growing rapidly. Large cities produce more than 4,000 tons of domestic garbage every day, of which food waste accounts for 50%. As a key point in my country's waste treatment field, how to effectively treat these organic, water-rich and perishable food waste has always been the focus of the industry.

[0003] In recent years, driven by the rapid development of the catering industry, the output of restaurant kitchen waste has risen rapidly. The national restaurant kitchen waste output has increased from 78.28 million tons in 2010 to 108 million tons in 2018. In 2018, the investment scale of national restaurant kitchen waste treatment has reached 3.434 billion yuan. With the improvement of various links, the market space will be further expanded. The final products produced by the treatment of restaurant waste include feed, biodiesel, fertilizer, etc. At present, the scale of final treatment products of restaurant waste in my country is not high, the output is small, the application is limited, and the development potential is great. The utilization rate of restaurant waste is still not high. At present, the national output is only 1 million tons, accounting for less than 1% of the total diesel. Many states in the United States have used biomass diesel, with an annual output of more than 3 million tons. France, Brazil and other countries require that diesel must be mixed with 5% biodiesel. With the release of the future market, my country's biodiesel will also usher in rapid development. Summary of the invention

[0010] By using this application, the reactor is used to make the food waste rot and decompose under the action of biological bacteria, and the high oil and high water content in the food waste are separated from the food residue.

Due to the friction between the wear-resistant orifice plate and the second end plate, the drain hole is prevented from being blocked due to the accumulation of solid waste at the drain hole. The water storage cavity formed by the water hole can also solve the problem of uneven water discharge.

[0016] Furthermore, the gas collecting bin includes a bottom plate fixedly connected to the top of the kettle body and a top plate fixed on the bottom plate, an air collecting cavity is formed between the top plate and the bottom plate, an air collecting hole connecting the inner cavity of the kettle body and the air collecting cavity is provided on the bottom plate, one side of the bottom plate extends outward beyond the kettle body to form a discharge part, a drainage hole and the first exhaust pipe are provided on the discharge part, the top of the first exhaust pipe is higher than the top of the drainage hole, the first exhaust pipe and the drainage hole both penetrate downward through the bottom surface of the discharge part, and the drainage hole is connected to the oil-water separator.

The drainage hole opening and closing device is used to control the opening and closing and opening degree of the drainage hole to control the flow rate of the discharged liquid.

[0075] The liquid discharged from the reactor enters the oil-water separator, and the odorous gas generated in the reactor first enters the gas collection bin, and then is blown into the deodorizer by the fan for treatment. The condensate generated in the gas collection bin is discharged from the drain hole and also enters the oil-water separator.

[0076] In the deodorizer, the odorous gas is first washed with water, then irradiated with ultraviolet rays, and finally discharged after being adsorbed by activated carbon.

[0077] In the oil-water separator, the waste oil separated from the waste water is separated through the oil recovery device, and the waste water after the waste oil is separated is discharged from the oil-water separator and enters the waste water treatment system for further treatment.

[0078] When the reactor is not in operation, the inner cavity of the reactor is cleaned by using a cleaning water pipe.
