Abstract

The invention discloses a device and process for high-quality processing of waste oil cooking coal. The device includes a decontamination and purification tower, a grease storage tank, and a preprocessor connected in sequence. The crusher is connected in sequence with the first grading screen, the first lifting machine, the first hoist is connected to the preprocessor, the bottom of the preprocessor is connected to the first filter press, the side is connected to the middle tank of grease, the bottom of the first filter press is placed to place mineral storage tanks, and the bottom of the side is connected to the filter press pool; the pulverizer is sequentially Connect the second grading screen and the second hoist, the second hoist is connected to the high-quality processor, the middle grease tank and the grease storage tank are respectively connected to the top of the high-quality processor. The invention uses waste oil as the medium of lignite upgrading and processing, turns waste oil into treasure and recycles it, develops a new way of waste oil utilization and high-quality coal processing, changes the heating and dehydration mode of gas heat transfer, and is widely used The temperature conditions are more optimized, the device and process have a wide range of applications, are conducive to environmental protection, and realize the classification and cascade utilization of coal.

Description

technical field [0001] The invention relates to a high-quality processing device and process for cooking waste oil and fat, and belongs to the fields of waste oil utilization technology and coal processing. Background technique [0002] The return of waste oil to the dining table will seriously endanger people's health. It comes from a wide range of sources, such as frying oil, waste oil, hog oil, and expired oil. "Gutter oil" generally refers to the oil produced and processed from non-food raw materials such as kitchen waste, meat processing waste, and livestock and poultry products that fail inspection and quarantine. Because animal and vegetable fats and oils will produce highly toxic aflatoxin, benzopyrene and other carcinogens through high-temperature oxidation, which will cause great harm to people's health. Therefore, researching and developing the utilization of waste oil has important social value and significance to benefit and protect people's healthy life. [0...
