At present, there are many research methods for improving the quality of coal by reducing the water content, especially the dehydration and upgrading of lignite. Chinese patent CN104178191A mentions that lignite accounts for 40% of the global reserves and 13% of China's reserves. Due to the high moisture content (about 20% -60%), low calorific value, easy weathering and spontaneous combustion, high transportation cost per unit energy, not conducive to long-distance transportation and storage

Abstract
The invention discloses a device for boiling coal with waste oil and a method for using the same. The device includes an impurity removal and purification tower, a grease storage tank, and a waste oil coal boiler connected in sequence, and the crusher is sequentially connected with a lifter and a waste oil coal boiler, and the waste oil coal boiler has a mixer, a discharge valve, a solid outlet Feed port, filter screen, coal pusher, solid discharge port is connected to the conveyor belt, the bottom of the waste oil coal cooker is connected to the first filter press, the side is connected to the second filter press, the conveyor belt is connected to the coal bunker, and the first filter press Mineral storage tanks are placed in the lower part, the side bottom is connected to the filter press pool, the coal slime storage tank is placed in the lower part of the second filter press, the side bottom is connected to the fractionation tower, the top of the fractionation tower is connected to the collection tank, and the bottom is connected to the grease storage tank. The present invention uses waste oil as the medium of lignite upgrading and processing, turns waste into treasure and recycles waste oil, and develops a new way of waste oil utilization and lignite upgrading; lignite dehydration can be realized at room temperature, and the operation is simple and convenient, and the application Wide range, no waste, good for environmental protection.
Description
technical field [0001] The invention relates to a device for boiling coal with waste oil and a method for using the same, and belongs to the fields of waste oil utilization technology and coal processing. Specifically, it relates to a device and a use method for dehydrating and demineralizing lignite by using waste oil such as frying oil, gutter oil, hogwash oil, and expired oil as a medium to improve lignite coal quality. 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 o...
