One step, volume and quality are greatly reduced after sludge drying, and bacterium and pathogen are effectively removed, while nutritional ingredient and calorific value
It is maintained, can further fill, compost, burning and land use.
Sludge heat drying can be divided into direct heat drying, indirect thermal drying technique according to thermal medium and the sludge way of contact.Between
Connect the application that heat drying is heat transfer drying technique.The heating and drying machine wall of thermal medium keeps the sludge in desiccation machine heated, moisture
Evaporation.Thermal medium does not contact directly with sludge in drying process, so heat transfer efficiency is relatively low, moisture evaporation rate is low.And one
As factory moisture percentage in sewage sludge be substantially 80-85%, be not able to satisfy actual demand using indirectly drying.Direct heat drying is
The application of thermal convection drying technique.Enter in desiccation machine after thermal medium heating and directly contacts mixing with sludge, sludge heating, moisture
Evaporation.Thermal medium is directly contacted with sludge and is contaminated in the process, and the exhaust steam and waste water of discharge need to be through innoxious places
It is discharged after reason.The technology rate of heat transfer and moisture evaporation rate are higher.But at present still based on introduction of foreign technology and equipment, because
This selects reasonable drying process, safe and stable, inexpensive and handle sludge on a large scale, is that current sludge drying is badly in need of solution
Certainly the problem of.

It is introduced on pipeline in the foul smell, the high-temperature tail gas of the pyrolysis gasification furnace is connected by exhaust pipe and the high-temperature tail gas upstream end
The heat source as heat exchanger is connect, is connected with the sludge drying being connected with the pyrolysis gasification furnace on the high temperature foul smell outlet side
Pipeline, setting is contained with the sludge Drying of sludge to be dried on the sludge drying pipeline.
Particularly, it is additionally provided with tail gas outlet side on the heat exchanger, is connected with vent gas treatment on the tail gas outlet side
Pipeline, the vent gas treatment pipeline will introduce tail gas treatment device by the high-temperature tail gas of heat exchanger and handle.
Particularly, the pyrolysis gasification furnace uses bilingual furnace, and the exhaust pipe enters the dual firing chamber of the bilingual furnace.
Particularly, the foul smell temperature in the sludge drying pipeline is 150 DEG C~200 DEG C.
Particularly, the garbage raw material is any or both mixture of house refuse, river sludge.
The beneficial effects of the utility model are that the environmentally-friendly sludge desiccation apparatus can be realized dirt compared with prior art
The desiccation of mud removes the foul smell in rubbish workshop, and high efficiency utilizes the fume afterheat of pyrolysis oven generation, does not need in drying process outer
The input of portion's energy will not generate subsequent contamination.Not only simple process, it is easy to accomplish；And energy conservation, environmental protection, sludge drying
It is high-efficient.
