River channel sludge recycling system

Abstract

The invention relates to the technical field of river channel cleanout and particularly relates to a river channel sludge recycling system. The river channel sludge recycling system comprises an extraction device, a cleaning device, a solidifying device, a cutting device, a drying device, a conveying device and a cement producing device, wherein the extracting device is used for extracting sludge, the cleaning device is used for removing waste from the sludge, the solidifying device is used for solidifying the sludge into blocky sludge, the cutting device is used for cutting the blocky sludge into powdery sludge, the drying device is used for drying the powdery sludge, the conveying device is used for conveying the powdery sludge, and the cement producing device is used for producing cement from the powdery sludge. The river channel sludge recycling system is used for recycling the sludge, so that the wasting of resources is avoided, and secondary pollution is prevented.

Description

technical field [0001] The invention relates to the technical field of river dredging, in particular to a river mud resource recovery system. Background technique [0002] Silt is deposited in still water or slow flowing water environment, formed by physical, chemical and biochemical actions, unconsolidated soft fine-grained or very fine-grained soil, which belongs to modern recent sediments. [0003] River dredging is to use mechanical equipment to blow and stir the silt deposited on the bottom of the river into turbid water, which flows with the river, so as to dredge the river, make the river deeper, wider, clearer, and restore the normal function of the river. . But let the silt flow away with the river water. On the one hand, because the river silt contains a lot of nutrients, it will cause a waste of resources if it flows away directly. On the other hand, the soil will be lost directly, resulting in a waste of a lot of land resources, which is harmful to the ecologica...

Problems solved by technology

But let the silt flow away with the river water. On the one hand, because the river silt contains a lot of nutrients, it will cause a waste of resources if it flows away directly. On the other hand, the soil will be lost directly, resulting in a waste of a lot of land resources, which is harmful to the ecological environment. Cause irreparable damage. In the third aspect, most of the sludge contains heavy metals and organic pollutants, which will inevitably cause secondary pollution to the surrounding environment.
