Abstract

The invention discloses a sludge treatment system, which comprises a drying treatment device used for drying sludge, a mixed material grinding device used for mixing the dried sludge with pulverized coal to grind a mixed material, and a gasification treatment device used for gasifying the ground mixed material; the drying treatment device is provided with a discharge port, which is communicated with the feed port of the mixing and grinding device, and the discharge port of the mixing and grinding device is communicated with the inlet of the gasification treatment device. According to the system, the sludge is subjected to drying treatment to remove moisture in the sludge, so that the problem that the heat value of the sludge with high moisture content is low is solved, the sludge disposal amount of a gasification furnace is increased, the dried sludge and pulverized coal are co-gasified by utilizing a mature dry pulverized coal gasification furnace, new disposal equipment is not needed, the sludge disposal cost and the operation cost are reduced, and synthesis gas with high combustible components is generated; the sludge treatment system can be used for synthesizing chemicals or used as clean fuel gas while the gasified residues and other inorganic matters can be used for making bricks, and the resource utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of solid waste disposal, in particular to a sludge treatment and disposal system. Background technique [0002] In recent years, with the rapid development of my country's national economy and the continuous improvement of living standards, the treatment capacity of urban sewage and industrial wastewater has continued to increase, and sediments, particles, floating objects and various forms of pollutants in sewage are separated as sludge However, the investment in sludge disposal facilities is relatively high. The cost of sludge treatment and disposal in sewage plants in my country accounts for 24% to 45% of project investment and operating costs, while developed countries in Europe and the United States The proportion of national sludge treatment and disposal costs in the total investment of sewage treatment plants has even reached 50% to 70%. In addition, the sludge has complex components and contains a lar...
