Technical field
The utility model relates to field of Environment Protection, is specifically related to a kind of sludge treating system.
Background technology
At present, in field of Environment Protection, the common methods of sludge treatment has following several: the 1. sanitary landfill of mud, and this method of disposal is simple, easily row, cost are low, and mud does not need again high dehydration, strong adaptability.But also there are some problems in Sludge landfill, espespecially the formation of loading embeading percolation liquid and gas.Percolate is a kind of liquid that is heavily polluted, if site selection of landfill or move improper can polluted underground water environment.The gas that landfill yard produces mainly is methane, can not set off an explosion and burn if do not take appropriate measures.2. the direct soil utilization of mud, the mud soil directly utilizes because of less investment, energy consumption is low, working cost is low, organic moiety can change into the soil improvement agent advantage that becomes to grade, be considered to have most a kind of disposal options of development potentiality, scientific and reasonable soil utilization, but the negative effect that reduce mud brings.The utilization of forest land and municipal administration greening is because being difficult for causing the pollution of food chain to become the effective means that the mud soil utilizes.Mud is used for reparation and the reconstruction in the soil (soil that need to reclaim such as mining site soil, forest harvesting field, refuse landfill, area of heavy damage, earth's surface etc.) of serious disturbance, reduce the potential threat of mud to the human lives, not only disposed mud but also recovered ecotope.3. the burning of mud is directly burned behind the wet sludge anhydration again and is used comparatively generally, directly burns not only very difficultly through the mud of mummification, and also is extremely uneconomic on energy consumption.Method for sludge treatment take burning as core is one of method for sludge treatment the most thoroughly, and it can make the whole carbonizations of organism, pathogen kill, to greatest extent reduce mud volume; Investment is large but its shortcoming is treatment facility, and processing costs is high, and cost of equipment maintenance is high, and produces the strong carcinogen Dioxins.
In sum, existing sludge treatment mode still exists following defective: 1. the level of automation of sludge handling process is low; 2. process the pollution that does not thoroughly still exist environment; 3. expend fuel many, waste energy.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of sludge treating system, this sludge treating system adopts automatic equipment to process the second stage employ fully of the energy in the mud, have level of automation high, save thoroughly characteristics of the energy and sludge treatment.
The technical solution of the utility model is: a kind of sludge treating system comprises that mud receives warehouse, low temperature pyrolyzer reactor, mechanical presses desiccation apparatus, dewatered sludge stacking field and fluidized-bed combustion boiler, mud receives in the warehouse and is provided with worm conveyor and sludge lifting pump, the sludge lifting pump outlet is communicated with the low temperature pyrolyzer reactor, the below of low temperature pyrolyzer reactor is provided with the mud material-stored pool, in the mud material-stored pool agitator is installed; Be provided with the sludge pump group between mud material-stored pool and the mechanical presses desiccation apparatus, dewatered sludge is stacked the exit that the field is positioned at the mechanical presses desiccation apparatus, and fluidized-bed combustion boiler and dewatered sludge are stacked between the field and be provided with chapelet and rotary conveyor.
Described mechanical presses desiccation apparatus is provided with water port, and water port links to each other with waste disposal plant.
Described mud receives on warehouse, low temperature pyrolyzer reactor and the mechanical presses desiccation apparatus and is equipped with the foul smell collection tube, the top that dewatered sludge is stacked the field is provided with gas skirt, the gas skirt top is connected with the foul smell collection tube, communicates with fluidized-bed combustion boiler after the foul smell collection tube converges.
The utlity model has following beneficial effect: owing to taking such scheme, mud is by external automobile transportation, directly be dumped into mud and receive warehouse, by worm conveyor and sludge lifting pump mud being delivered to the low temperature pyrolyzer reactor reacts, pass into simultaneously steam, conditioned mud discharging is installed agitator and is prevented sludge settling to the mud material-stored pool of its below in the mud material-stored pool.Mud in the mud material-stored pool carries out the mechanical presses dehydration again in the sludge pump group rises to the mechanical presses desiccation apparatus, moisture percentage in sewage sludge is reduced to water ratio about 30% by about 80%, the dewatered sludge that obtains is discharged into dewatered sludge and stacks a stacking, be transported to the fluidized-bed combustion boiler internal combustion through chapelet and rotary conveyor again, the abundant second stage employ of the energy of mud.The utility model level of automation is high, saves the energy, and sludge treatment is thorough.
