Description
Technical field
The utility model relates to the application of flue gas of refuse burning waste heat and technical field of sludge treatment, relates in particular to a kind of system of utilizing fume afterheat lignin-sludge.
Background technology
In general, in order not cause the secondary pollution of environment, need to after the second-stage treatment of sewage disposal, add one sludge treatment technique.The target of sewage disposal separates and realizes again by impurity in water is condensed into solid form from fluid.This concentrated qualitative change is called mud, because having comprised a large amount of objectionable impuritiess, need to properly dispose.The principle of sludge treatment is " minimizing, stabilization, innoxious and resource utilization ", and main methods comprises sanitary landfill, compost, mummification, burning etc.Sanitary landfill and compost method are simple, Yi Hang, cost are low, but easily cause secondary pollution, do not meet the principle of Sustainable development.Mummification is using artificial thermal source carries out deep dehydration to mud treatment process with industrial equipment, is very limitting for the volume that reduces mud.Taking burn as the method for sludge treatment of core be one of method for sludge treatment the most thoroughly, it can make the whole carbonizations of organism, pathogen kill can reduce sludge volume to greatest extent; But the investment of present sludge incineration treatment facility is large, and processing costs is high, and cost of equipment maintenance is high.
Utilize the system (notification number: CN203116031U) of waste incineration and generating electricity fume afterheat burning sludge to disclose a kind of system of utilizing waste incineration and generating electricity fume afterheat burning sludge, include incinerator, mud burning treatment apparatus, e Foerderanlage and smoke eliminator, the resource that makes full use of garbage burning factory, has reduced drying process.Although this system device is simple, directly not burn not only very difficultly through the mud of mummification, efficiency is low, and in energy consumption, is also extremely uneconomic.
Summary of the invention
The purpose of this utility model is to overcome described in above technology not enough, and the sludge treating system of the simple and less energy consumption of a kind of system is provided.
The utility model is achieved through the following technical solutions:
A kind of system of utilizing fume afterheat lignin-sludge, comprise incinerator, it is characterized in that: the rotary kiln that also comprises front end dewatered sludge, rear end burning sludge, the exhanst gas outlet of described incinerator connects the tail end air intake of rotary kiln by high-temperature flue gas pipeline, the front end of described rotary kiln is provided with material inlet, and the front end air outlet of described rotary kiln is connected to incinerator by low temperature exhaust gas pipeline.The high-temperature flue gas of waste incineration enters from rotary kiln tail end, makes the front end mummification of mud at rotary kiln, burns at the tail end of rotary kiln.After high-temperature flue gas dewatered sludge, become low temperature exhaust gas, return incinerator, tail gas is reused, environmental protection and saving.
Further, between described rotary kiln front end venting port and low temperature exhaust gas pipeline, be provided with low temperature exhaust gas blower fan, high-temperature flue gas be drawn onto to the mummification of mud place, and the low temperature exhaust gas after dewatered sludge is extracted into low temperature exhaust gas pipeline.
Further, the junction of described low temperature exhaust gas pipeline and incinerator is provided with low temperature exhaust gas and returns spout, can fast tail gas be sucked back to the burner hearth of incinerator.
Further, the caudal end egress of described rotary kiln is provided with out mouth mask, prevents that the lime-ash dust that sludge incineration produces from flying upward.
The utility model system is simple, without increasing sludge drier and smoke processing system, utilize waste incineration high-temperature flue gas directly mud to be dried and to be burned, sludge treatment one-time-reach-place, avoided Complex Heat device thermosteresis, overall thermal loss is few, and thermo-efficiency is high, energy consumption is little, and running cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of the system of utilizing fume afterheat lignin-sludge described in the utility model;
In figure: 1-incinerator, 2-rotary kiln, 3-material inlet, 4-high-temperature flue gas pipeline, 5-low temperature exhaust gas pipeline, 6-go out mouth mask, 7-low temperature exhaust gas blower fan, 8-low temperature exhaust gas and return spout, 9-ash slag bath, 10-flue gas purification system, 11-chimney, 12-induced draft fan.
Embodiment
By the drawings and specific embodiments, the utility model is further detailed below.
As shown in Figure 1, the system of utilizing fume afterheat lignin-sludge described in the utility model, mainly comprises incinerator 1, rotary kiln 2.The front end of rotary kiln 2 is provided with material inlet 3, by material inlet, mud is delivered to rotary kiln 2.The tail end air intake of rotary kiln 2 is communicated with the venting port of incinerator 1 by high-temperature flue gas pipeline 4, and the caudal end egress of rotary kiln 2 is provided with out mouth mask 6, goes out mouth mask 6 and is provided with grey slag bath 9 below.The front end venting port of rotary kiln 2 is provided with low temperature exhaust gas blower fan 7, and the other end of low temperature exhaust gas blower fan 7 is connected to the low temperature exhaust gas pipeline 5 that is communicated with incinerator 1 burner hearth.The exit of low temperature exhaust gas pipeline 5 is provided with low temperature exhaust gas and returns spout 8, and accesses incinerator 1.Incinerator 1 is communicated with flue gas purification system 10, notifies chimney 11 to discharge after gas cleaning, between flue gas purification system 10 and chimney 11, is provided with induced draft fan 12.
The high-temperature flue gas of approximately 1000 DEG C is extracted out from the boiler first channel of incinerator 1, sends into the tail end of rotary kiln 2, and mud is sent into the front end of rotary kiln 2 from material inlet 3.Once high-temperature flue gas arrives rotary kiln 2, will be absorbed by low temperature exhaust gas blower fan 7, suck rotary kiln 2 front ends and exit, then return spout 8 and suck back the bottom of incinerator 1 by low temperature exhaust gas.High-temperature flue gas and mud inverse motion, the energy that sludge incineration produces is all directly used in mummification.The waste gas of incinerator 1 mixes with the smoke height turbulent flow of rotary kiln 2, has guaranteed the perfect combustion of all gas, avoids producing excessive nitrogen protoxide.
The tail gas of approximately 300 ° of C is extracted out from the front end of rotary kiln 2, is admitted in the burner hearth of incinerator 1 by low temperature exhaust gas pipeline 5.The lime-ash that sludge incineration produces drops to grey pit by going out mouth mask 6, and incinerator 1 and rotary kiln 2 share grey slag bath 9.Mud burns with rotary kiln 2 separately, does not affect the processing power of incinerator 1.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
