Abstract

The invention discloses a coking process and device. The coking process comprises the following steps: mixing waste oil with coal in a pretreatment device through impurity removal, and then separatingpretreated coal and liquid through vacuum filtration; the pretreated coal enters a pre-pyrolysis device after being crushed and screened, and grease and water are separated from liquid through oil-water separation; the separated oil enters a pre-pyrolysis device to be mixed and reacted with the pretreated coal, and separated water is subjected to filter pressing to obtain filter pressing water and mineral substances; filtering the reacted oil and coal mixture in vacuum, collecting the filtered oil, and coking the filtered coal in a coke oven to obtain coke; the collected filtered grease is subjected to filter pressing to obtain coal slime and filter-pressed grease, the coal slime and the filtered coal are loaded into a coke oven together for coking, low-boiling-point substances are separated from the filter-pressed grease through distillation firstly, then medium-boiling-point substances are separated through rectification, and the rectified grease of the high-boiling-point substancesreturns to the pretreatment device for recycling. A new way of bituminous coal coking processing is developed, the coal types of coking coal are expanded and the shortage of coking coal resources isimproved.

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...
