Abstract
The utility model discloses a sludge low temperature carbonization system which comprises a sludge storage pool, a heat exchanger, a carbonization reaction tower, a combustor, a centrifuge and a carbonized product storage tank. The system is characterized in that a high pressure slurry pump is arranged between the sludge storage pool and the heat exchanger; a feeding inlet of the carbonization reaction tower is connected with a discharge hole of the heat exchanger; a discharge hole of the carbonization reaction tower is sequentially connected with the heat exchanger and the centrifuge; a top exhaust tube of the carbonization reaction tower is connected with the combustor through a pipeline. By adopting the system, sludge can be subjected to carbonization in an anaerobic low temperature state, organic components in the sludge are split under anaerobic conditions, carbon dioxide can be separated from solid, combustible gas volatile organic compounds can be generated, the dehydration property of the sludge is improved, sludge carbonization is achieved without combustion, and the carbonized substances can be recycled and reused as novel resources.
Description
Technical field
The utility model relates to Sludge Disposal Techniques field, is specifically related to a kind of sludge at low temperature carbonization system.
Background technology
At present, the sludge disposal that sewage work produces adopts landfill, burning, solidify etc., because moisture percentage in sewage sludge is very high, sludge drying needs mass energy, adopt landfill to take a large amount of land resources, and can produce the problem of leachate contamination, so apparatus system that should more employing recyclings, to improve the benefit of mud management, realize the cycling and reutilization of mud.
Utility model content
The purpose of this utility model is to provide a kind of sludge at low temperature carbonization system, under anaerobic low-temperature condition, mud is carried out to carbon element reaction, organic constituent cracking under oxygen free condition in mud, carbonic acid gas is separated from solid, produce inflammable gas volatile organic matter, improve dewatering performance of sludge, without burning, realize mud carbon element, carbide is as new resources regeneration.
The purpose of this utility model is achieved through the following technical solutions: a kind of sludge at low temperature carbonization system, comprising: mud storage pool, interchanger, carbonation reaction tower, burner, separating centrifuge and carbonated product storage tank; It is characterized in that, between described mud storage pool and interchanger, be provided with high pressure slurry pump; The opening for feed of described carbonation reaction tower is connected with the discharge port of interchanger, and the discharge port of carbonation reaction tower connects interchanger and separating centrifuge successively, and the top vapor pipe of carbonation reaction tower is connected with burner by pipeline.
Described centrifugation motor spindle is provided with liquid discharge pipe.
Described burner is connected with combustion gas storage tank by pipeline.
In sum, the beneficial effects of the utility model are: organic constituent cracking under oxygen free condition in mud, and carbonic acid gas is separated from solid, produces inflammable gas volatile organic matter, interchanger recycling heat energy; 200～240 ℃ of low-temperature decomposition; Improve dewatering performance of sludge, carbonization mud is easy to dehydration; Without burning, pollute little cost low, do not produce the obnoxious flavoures such as dioxin and carbonic acid gas, carbon granule is small, easily recycling; Without burning, realize carbon element, carbide recycles completely as new resources.
