Abstract

The invention discloses a coking process and a device. Waste grease is mixed with coal in a pretreatment device through decontamination, and then pretreated coal and liquid are separated by vacuum filtration; The liquid is separated from oil and water to separate oil and water; after separation, the oil enters the pre-hydrolysis device and the pretreated coal is mixed for reaction, and the separated water is subjected to pressure filtration to obtain pressure filtered water and minerals; the reacted oil and coal mixture The filtered oil is collected, and then the filtered coal is coked in a coke oven to obtain coke; the collected filtered oil is subjected to pressure filtration to obtain coal slime and filter press grease, and the coal slime and the filtered coal are put into the coke oven together for coking, and then pressed. Filter the grease to separate low boilers by distillation first, and then separate medium boilers by rectification, and the rectified grease with high boilers is returned to the pretreatment device for recycling. The invention develops a new way of coking and processing of bituminous coal, expands the coal types of coking coal, and improves the shortage of coking coal resources.

Description

technical field [0001] The invention relates to a coking process and device, belonging to the fields of waste oil utilization 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, the research and development of waste oil utilization methods benefit and protect people's healthy life, which has important social value and significance. [0003] Coal occupies a dominant position in the ener...
