Description
Apparatus field
This utility model relates to a kind of sludge at low temperature cracking apparatus, is specifically related to domestic sludge deep dehydration and low temperature pyrolyzer
Anhydration and incineration equipment.
Background equipment
At present, along with improving constantly for the treatment of rate of domestic sewage, city river view and living environment are changed really
Kind, but how the mud that produces of sewage treatment plant is disposed and is increasingly becoming one of problem that each big city leader has a headache most.At present
The sewage treatment plant of China ninety percent is above that the mud after dehydration is directly transported to refuse landfill and carries out landfill disposal, but due to
Dehydrated sludge moisture content is typically 75～about 80%, and its anti-shear ability is very poor, causes the garbage loading embeading vehicle cannot normal work
Make, in consideration of it, the refuse landfill of various places all starts to reject dewatered sludge.
For problem above, the process of current domestic mud has carried out some and has improved, wherein based on anhydration and incineration
One of processing method wanted, and applied in some engineerings, but actual motion gets off, and its operating cost is higher,
Seriously constrain the popularization in China medium-sized city of the specific resistance to filtration engineering.
Utility model content
(1) plant issue to be solved
For solving the problems referred to above, the utility model proposes a kind of sludge at low temperature cracking apparatus.
(2) equipment scheme
Sludge at low temperature cracking apparatus of the present utility model, include successively interconnective modifying device, deep dehydrator,
Desiccation machine, low-temperature cracking furnace and cracking gas combustion furnace, described deep dehydrator is barrier film high pressure filter press, described dry
Change machine is blades type drying machine.
Further, it is provided with a certain proportion of FeCl3 and CaCO3 in described modifying device.
Further, described desiccation machine mainly uses conduction oil or steam heat conduction.
Further, described cracking gas combustion furnace connects conduction oil or steam.
Further, in described low-temperature cracking furnace, it is set to oxygen-free environment, and added with special-purpose catalyst.
(3) beneficial effect
This utility model is compared with existing equipment, and it has the advantages that sludge at low temperature of the present utility model splits
Solution equipment, the cracking gas Main Ingredients and Appearance of generation is the alkane of short chain, hydro carbons, and calorific value is higher, and burning is convenient, produces pollution little, and
The cracking gas produced fully enters combustion furnace burning, and the heat of generation is used for heating conduction oil to promote mummification.And this practicality
It is not required to during novel sludge anhydration burning add auxiliary fuel, is not required to use the techniques such as complicated fluidized bed incinerator, tool
Have simple to operate, the advantages such as cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly that the equipment scheme in this utility model embodiment or existing equipment, below will be to embodiment
Or the required accompanying drawing used is briefly described in existing equipment description, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, from the point of view of the conventional equipment personnel of this area, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is block flow diagram of the present utility model.
Detailed description of the invention
A kind of sludge at low temperature cracking apparatus, includes interconnective modifying device, deep dehydration successively
Device, desiccation machine, low-temperature cracking furnace and cracking gas combustion furnace, described deep dehydrator is barrier film high pressure filter press,
Described desiccation machine is blades type drying machine.
A certain proportion of FeCl3 and CaCO3 it is provided with in described modifying device.
Described desiccation machine mainly uses conduction oil or steam heat conduction.
Described cracking gas combustion furnace connects conduction oil or steam.
Oxygen-free environment it is set in described low-temperature cracking furnace, and added with special-purpose catalyst.
Sludge at low temperature cracking apparatus of the present utility model, has the advantages that sludge at low temperature of the present utility model splits
Solution equipment, when coming into operation, it is achieved the mud mechanical dehydration again after being dehydrated each sewage treatment plant so that it is moisture content is by former
75～80% come are reduced to about 60 ~ 65%, and its moisture contained can reduce half, and volume may decrease to original about 60%,
Greatly reduce the energy consumption of follow-up mummification cracking burning process input.Use modifying device that former dewatered sludge is entered before deep dehydration
Row is quenched, i.e. adds a certain proportion of FeCl3 and CaCO3 in the mud of modifying device, makes the cell wall of antibacterial destroy,
Intracellular moisture separate out, quenched after mud enter barrier film high pressure filter press.
Mud after deep dehydration sends into blades type drying machine by conveying worm, by blades type drying machine by its mummification
To 10～20% moisture content, it uses heating agent can be conduction oil or water vapour, and heat energy comes from follow-up combustion furnace.
Mud temperature after mummification probably at about 950C, sends into low-temperature cracking furnace by airtight conveyer, due to this
Engineering is oxygen-free environment in using low-temperature cracking furnace, and uses special-purpose catalyst, can make dewatered sludge in the range of 200 ~ 2500C
I.e. there is cracking reaction, mud can be finally decomposed to cracking gas and lime-ash.This part lime-ash moisture content is low, substantially by inorganic matter
Composition, is widely used as the making raw material of the building materials such as brickmaking.
The cracking gas Main Ingredients and Appearance that this utility model produces is the alkane of short chain, hydro carbons, and calorific value is higher, and burning is convenient, produces
Pollute little.The cracking gas that this utility model produces fully enters combustion furnace burning, and heating conduction oil is for mummification.
The utility model has the advantages that technique is simple, equipment is small, owing to using deep dehydration and low temperature pyrolyzer device,
It is not required to add auxiliary fuel during sludge anhydration burning, and is not required to use the devices such as complicated fluidized bed incinerator, Ke Yibao
Card is in the case of sludge calorific value is relatively low, it is achieved add without auxiliary fuel, overall operation low cost, reduced investment.
Embodiment described above is only to be described preferred implementation of the present utility model, not to this practicality
Novel spirit and scope are defined.On the premise of without departing from this utility model design concept, this area ordinary person couple
Various modification that equipment scheme of the present utility model is made and improvement, all should drop into protection domain of the present utility model, this reality
By the novel equipment content being claimed, all record in detail in the claims.
