The technical scheme adopted for realizing the purposes of the patent is as follows: the system for treating the organic biochemical sludge containing oil in the coal-to-liquid by using the water-coal-slurry gasification furnace comprises the following treatment flows and equipment facilities: the sludge blending tank is characterized in that a pipeline is arranged at the bottom of the sludge blending tank, organic biochemical sludge which is not dehydrated and contains oil can automatically flow to a sludge cutting machine through the pipeline, an inlet valve and an outlet valve are respectively arranged on an inlet pipeline and an outlet pipeline of the sludge cutting machine, an outlet pipeline of the sludge cutting machine is connected to an inlet of a sludge conveying pump, an inlet valve and an outlet valve are respectively arranged on an inlet pipeline and an outlet pipeline of the sludge conveying pump, a flushing water pipeline and a valve are arranged at the branch of the inlet pipeline, an outlet pipeline of the flushing water pipeline is connected to an inlet of a coal pulverizer, a discharge pipeline of the coal pulverizer is connected to an inlet of a coal slurry drum screen, a discharge pipeline of the coal slurry drum screen is connected to an inlet of a coal slurry tank, a coal slurry tank is internally provided with a coal slurry stirrer, a discharge pipeline of the coal slurry tank is connected to an inlet of a high-pressure coal slurry pump, and an outlet pipeline of the high-pressure coal slurry pump is connected to a coal slurry feeding port of a gasification furnace.
This patent can obtain following beneficial effect: the coal-to-liquid byproduct non-dehydrated organic biochemical sludge is doped to prepare the water-coal-slurry which is used as a raw material of a water-coal-slurry gasification furnace, and high-temperature and high-pressure reaction treatment is carried out in the gasification furnace, so that the harmless treatment of the non-dehydrated oil-containing organic biochemical sludge of the coal-to-liquid byproduct is successfully realized, organic components such as carbon, hydrogen and the like contained in the sludge are fully recycled, and the environmental protection benefit and the economic benefit are remarkable.
The organic biochemical sludge without dewatering oil does not need to be dewatered by a dewatering machine, so that the electricity cost of the dewatering machine, the chemical cost of the flocculating agent and the transportation cost of the dewatered biochemical sludge are saved.
The organic biochemical sludge without dehydrated oil is used as coal grinding water, so that the using amount of the water produced by the coal grinding machine is reduced, and the water cost is saved.
Saves the disposal cost of the oily organic biochemical sludge and eliminates the environmental protection risk of the organic biochemical sludge in the transportation and disposal processes.
