Description

Technical Field

[0001] This utility model relates to the field of coal-to-oil technology, specifically to a wastewater treatment device for coal-to-oil production. Background Technology

[0002] Coal-to-oil (CTO) uses coal as a raw material to produce oil products and petrochemical products through chemical processing. It includes two technical routes: direct coal liquefaction and indirect coal liquefaction. Direct coal liquefaction involves catalytically hydrogenating coal under high temperature and pressure to synthesize liquid hydrocarbon fuels, removing sulfur, nitrogen, and oxygen atoms. Indirect coal liquefaction first gasifies the coal and then converts it into hydrocarbon fuels through Fischer-Tropsch synthesis. Due to its large reserves and relatively stable price, coal has become the preferred fuel for power production in China. However, the wastewater generated from CTO has high levels of organic pollutants and strong biological toxicity; direct discharge would seriously harm the ecological environment, necessitating the use of wastewater treatment equipment.

[0003] Patent application number CN202120105343.X discloses a wastewater treatment device for coal-to-oil conversion. By setting an observation port, the progress of static stratification can be observed, preventing the upper layer of oil from being extracted. The pH value of the wastewater is detected in real time by a pH meter and adjusted according to the displayed value. A coke powder filter is set to remove soluble oils from the wastewater, realizing multi-stage oil removal.

[0004] However, the aforementioned wastewater treatment device for coal-to-oil processes lacks a pretreatment device and a filtration system.
