Abstract

The invention provides a slag heat drying sludge incineration treatment system and a treatment method. The system comprises a boiler and a sludge sowing fan; a furnace slag discharging port is formed in the bottom of the boiler, a sludge feeding port is formed in the side wall of the boiler, an air outlet of the sludge sowing fan is communicated with the sludge feeding port by means of a sludge sowing pipeline, a hot air outlet is also formed in the side wall of the boiler, a set of furnace slag treatment equipment is connected to the furnace slag discharging port, a cold air suction inlet used for sucking cold air and realizing cooling of furnace slag in the equipment is formed in furnace slag treatment equipment and is communicated with the furnace slag discharging port, and the hot air outlet is communicated with an air inlet of the sludge sowing fan. The slag heat drying sludge incineration treatment system and the treatment method provided by the invention have the beneficial effects that air heating is completed by utilizing the incinerated furnace slag, and then sludge drying is completed by utilizing heated air; the heat energy utilization rate is high, the technological process is fully simplified, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to an incineration treatment system and treatment method for slag-discharging heat-dried sludge. Background technique [0002] As of 2015, the daily treatment capacity of urban sewage plants in my country has reached 137.84 million cubic meters, and the annual sludge production is about 35 million tons. It is estimated that by 2020, my country's municipal sludge production will reach 60 million to 90 million tons. At the same time, printing and dyeing, textile and other industrial enterprises also produce a large amount of sludge. [0003] At present, my country's existing sludge treatment technology mainly adopts the following three methods: [0004] 1. The sludge is sent directly to the boiler for combustion through a pump or conveyor. Although the process is simple, this method is only suitable for processing capacity due to the high moisture content of the ...
