Embodiment Construction

[0011] Such as figure 1 As shown, the present invention includes a drying mixer 3, a fluidized suspension furnace 4 and a high-efficiency cyclone dust collector 7, which are placed near the cement clinker burning system to dry and incinerate the sludge 1. The specific process is introduced as follows: the fresh sludge 1 with a water content of 75% directly enters the drying mixer 3, and the drying heat source of the mixer 3 comes from the tertiary air 2 heated by the kiln head of the cement clinker firing. After adding cold air, it enters the drying The temperature of the gas in the mixer 3 is 250°C. The sludge 1 exiting the drying mixer 3 is sent to the suspension furnace 4 with a fluidized bed, and the waste gas exiting the mixer 3 enters the suspension furnace 4 for further combustion. Coal powder 6 is supplemented in the furnace of the suspension furnace 4 so that the dried sludge 1 can be completely incinerated therein, and another part of the tertiary air 2 from the kiln...

Abstract

The treatment apparatuses of industrial and domestic sludge comprise stoving stirrer, fluidized shower furnace and high-efficiency cyclone dust collector near cement clinker baking system. The treating process includes stoving of fresh sludge with water content up to 75% in the stoving stirrer, baking in the shower furnace while making-up fuel, and feeding the output matter of the furnace to cement clinker baking system via cyclone cylinder. In the process, organic component is used as fuel, bacteria and foul gas are burnt completely, and inorganic components are coated with cement clinker.

Description

technical field [0001] The invention belongs to a method for treating sludge, in particular to a method for treating industrial and domestic sludge. Background technique [0002] With the development of industry and the improvement of people's living standards, environmental protection has attracted more and more attention. The sludge after a large amount of industrial and domestic sewage treatment is in urgent need of proper treatment, so that its harm to human beings can be minimized to zero. Some of the existing sludge disposal methods need to occupy a large amount of land and have hidden dangers of secondary pollution; some need to deal with a large number of residues; Therefore, there are more or less shortcomings in the existing sludge disposal technology. With the improvement of environmental protection requirements, it is urgent to completely realize the harmless and resourceful treatment of sludge. Therefore, a sludge disposal method was invented, which uses the ...
