Problems solved by technology

[0003] The current refining method refers to oil processing enterprises, and uses three-phase decanter centrifuges and disc centrifuges to complete. This method is unreasonable and uneconomical, because edible oil processing enterprises process high oil content in materials, and the purpose of the enterprise Mainly for purification, the unrefined remaining oil is not discarded, it will be recycled and concentrated to enter the next step of purification
In addition, all the food waste enters the three-phase decanter centrifuge, which has long running time, high degree of wear and high energy consumption.

Embodiment Construction

[0039] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not indicated are usually the conditions in routine experiments.

[0040] see figure 1 , the kitchen waste degreasing method of the present invention comprises the following steps:

[0041] (1) The kitchen waste is evenly conveyed to the drum sieve by a shaftless screw, and sieved and washed with circulating water at 45-50°C to obtain a kitchen slurry that removes large impurities. The drum sieve here is an invention The drum sieve disclosed in the patent application CN105381871A;

[0042] (2) The kitchen slurry is separated into a solid phase substance larger than 1mm and a ...

Abstract

The invention discloses a kitchen waste oil removing method. The kitchen waste oil removing method comprises the following steps that 1, kitchen waste is uniformly delivered to a rotary drum screen through a shaft-free helix and is washed with circulating water of 45-50 DEG C to obtain kitchen slurry without large impurities; 2, the kitchen slurry is subjected solid-liquid separation through a rotary fine grille and then is separated into solid-phase substance greater than 1 mm and kitchen slurry oil-water mixed liquid smaller than 1 mm; 3, the kitchen slurry oil-water mixed liquid is fed into a gravitational oil removing tank through an oil-water mixture inlet to separate crude oil; 4, the crude oil separated from the gravitational oil removing tank is fed into a three-phase horizontal screw decanter centrifuge through a pump for further purification and separation, and separated solid residues and waste water flow back to the gravitational oil removing tank. The kitchen waste oil removing method can achieve oil separation and recovery of kitchen waste.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a method for removing oil from kitchen waste. Background technique [0002] Food waste contains 2% to 4% of oil, and hog oil or waste oil contains about 40% of oil. In order to extract crude oil that can be further processed, a set of practical methods is needed. [0003] The current refining method refers to oil processing enterprises, and uses three-phase decanter centrifuges plus disc centrifuges to complete. This method is unreasonable and uneconomical, because edible oil processing enterprises process high oil content in materials, and the purpose of the enterprise It is mainly about purification, and the remaining unrefined oil is not discarded, but will be recycled and concentrated to enter the next step of purification. In addition, all the food waste enters the three-phase decanter centrifuge, which has long running time, high degree of wear and high energ...
