Description
Technical field
The invention belongs to sludge disposal technology, more particularly, to a kind of environmentally-friendly sludge desiccation apparatus.
Background technology
Treatment of Sludge principle is minimizing, stabilisation, harmless resource utilization.The main method of sludge treatment is mainly soil
Using, agricultural sludge, landfill, recovery energy and comprehensive utilization.Either any method, sludge drying are all important
One step, volume and quality are greatly reduced after sludge drying, and bacterium and pathogen are effectively removed, while nutritional ingredient and calorific value
Be 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 makes the sludge in desiccation machine be heated, moisture
Evaporation.Thermal medium does not contact directly with sludge in drying process, thus heat transfer efficiency than it is relatively low, moisture evaporation speed is low.And one
As the moisture percentage in sewage sludge that dispatches from the factory be substantially 80-85%, cannot meet the needs of actual using indirectly drying.Direct heat drying is
The application of thermal convection current drying technique.Enter after thermal medium heating in desiccation machine and mixing is directly contacted with sludge, sludge heating, moisture
Evaporation.Thermal medium is directly contacted and is contaminated with sludge in the process, and the exhaust steam and waste water of discharge need to be through innoxious places
Discharged after reason.The technology rate of heat transfer and moisture evaporation speed are higher.But at present still based on introduction of foreign technology and equipment, because
This selects rational 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.
The content of the invention
It is an object of the invention to provide a kind of environmentally-friendly sludge desiccation apparatus, it is with drying efficiency is high, energy saving and ring
The characteristics of guarantor, to solve the above problem present in mud drying process in the prior art.
For this purpose, the present invention uses following technical scheme：
A kind of environmentally-friendly sludge desiccation apparatus, it includes closed garbage raw material workshop, air-introduced machine, heat exchanger, sludge baking
Dry cylinder and pyrolysis gasification furnace, wherein, low temperature foul smell leading-in end, high temperature foul smell outlet side and high temperature tail are provided with the heat exchanger
Gas upstream end, the garbage raw material workshop introduce pipeline by foul smell and are connected with low temperature foul smell leading-in end, and the air-introduced machine is set
Introduced in the foul smell on pipeline, 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, the sludge drying being connected with the pyrolysis gasification furnace is connected with the high temperature foul smell outlet side
Pipeline, the sludge Drying for being contained with sludge to be dried is set on the sludge drying pipeline.
Especially, tail gas outlet side is additionally provided with the heat exchanger, vent gas treatment is connected with 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 handled.
Especially, the pyrolysis gasification furnace uses bilingual stove, and the exhaust pipe enters the dual firing chamber of the bilingual stove.
Especially, the foul smell temperature in the sludge drying pipeline is 150 DEG C~200 DEG C.
Especially, the garbage raw material be house refuse, any or both mixture of river sludge.
Beneficial effects of the present invention are that the environmentally-friendly sludge desiccation apparatus can realize sludge compared with prior art
Desiccation, removes the foul smell in rubbish workshop, and high efficiency utilizes the fume afterheat that pyrolysis oven produces, external energy is not required in drying process
The input of amount, will not produce subsequent contamination.Not only technique is simple, it is easy to accomplish；And energy saving, environmental protection, sludge drying efficiency
It is high.
