Abstract
The invention discloses a sludge dividing device with cutting blades. The sludge dividing device with the cutting blades comprises a pipeline body and the two cutting blades. The two cutting blades are perpendicularly arranged in an intersecting mode and welded to the inner portion of the pipeline body. The pipeline body is welded to the lower portion of a sludge inlet incinerator pipeline. According to the sludge dividing device with the cutting blades, the structure is simple, the manufacturing cost is low, the possibility that sludge sinks to the bottom is reduced due to the design of the cutting blades, damage caused by a funnel cap is remarkably reduced, and the operation stability of a fluidized bed boiler is improved.
Description
technical field
The invention belongs to the technical field of the clean incineration disposal of mud, relate in particular to a kind of feed arrangement with the shunting of cutter section mud.
background technology
The processing of mud is the industrialization running means take economic benefit as main drive, comprehensively more multiple method for sludge treatment and feature thereof.The advantage of sludge incineration is to realize rapidly and to greatest extent minimizing, and it has not only solved the outlet of mud but also take full advantage of the energy in mud, and needn't consider the inactivation treatment of pathogen.The heat energy recoverable of sludge incineration, toxic pollutant is oxidized, and the heavy metal activity in ashes reduces greatly.
Because dewatered sludge moisture content is generally in 80% left and right, in Practical Project, usually, the fewer actual conditions of mud handling capacity are more, if burn after adopting mummification, system complex investment is high.If mud is directly dropped in existing fluidized bed incinerator and is burned, because burning mixed mud amount is smaller, very little on the impact of original boiler, therefore, in Practical Project, adopt mud through sludge pump closed conveying to the direct process technology scheme of burning disposal in fluidized-bed combustion boiler.
But, mud directly adds fluidized-bed combustion boiler to occur: thus bulk mud may directly be fallen the problem that causes the quenching of blast cap chilling to damage above blast cap, has accelerated the infringement of blast cap, affects the normal operation of fluidized-bed combustion boiler, often blowing out maintenance, causes great economic loss.
Therefore, under this background, the one band cutter section mud part flow arrangement that research and development and exploitation have autonomous property right has great importance, pipe interior structure is through improving, on the one hand reduce as far as possible mud transporting resistance, make on the other hand mud size be decreased to approximately original 1/4, can greatly reduce like this possibility that mud sinks to the bottom, significantly reduce the infringement of blast cap, the stable operation that improves boiler.
summary of the invention
The object of the invention is to overcome current sludge incineration and directly enter the sludgd deposition of incinerator bulk to the problem that causes blast cap chilling quenching well damage on blast cap, a kind of band cutter section mud part flow arrangement is provided, and this device makes mud high efficiency shunting before entering incinerator.
The object of the invention is to be achieved through the following technical solutions: a kind of band cutter section mud part flow arrangement, it is mainly made up of pipe main body and two cutter sections, and wherein, two cutter sections are in vertical distribution, and are welded in pipe main body.
Further, the material of described cutter section and pipe main body is all 2520 stainless steels (06Cr25Ni20); Described cutter section is tapered blade, and width is 40-60mm, is highly 60-100mm; Described pipe main body length is 80-120mm, is welded in mud and enters incinerator pipeline bottom; Welding material is 2520 stainless steels (06Cr25Ni20).
The invention has the beneficial effects as follows, before mud is normally transported to band cutter section mud part flow arrangement, the cutter tangent plane that mud is cut through blade cutter, make its sludge volume that originally entered boiler reduce to original 1/4, alleviated weight simultaneously, and make the dispersed burner hearth that is distributed to, the infringement of the bottom of avoiding directly falling into burner hearth to blast cap.The design that cutter is cut blade can significantly not increase the resistance that mud is carried, meanwhile, mud is split into 4 parts rapidly through cutter tangent plane, and the mud that enters burner hearth is effectively disperseed, enter after burner hearth anhydration and incineration rapidly, thus the avoided bulk sludge blockage cross section of pipeline and the possibility sinking to the bottom.
The present invention is simple in structure, and cost is low: with respect to additive method, the method does not need to spend a large amount of man power and materials, saves a large amount of time, and does not need to buy expensive equipment, reduces the cost of equipment.
Accompanying drawing explanation
Accompanying drawing is a kind of structural representation with cutter section mud part flow arrangement of the present invention:
In figure, pipe main body 1, cutter section 2.
The specific embodiment
Describe the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, band cutter section mud part flow arrangement of the present invention comprises pipe main body 1 and two cutter sections 2, and wherein, two cutter sections 2 are square crossing and distribute and be welded in pipe main body 1; The material of cutter section 2, pipe main body 1 and welding material is all 2520 stainless steels, and wherein, cutter section 2 is tapered blade, and width is 50mm, is highly 80mm; Pipe main body length is 100mm, is welded in mud and enters incinerator pipeline bottom.Mud is transported to pipeline bottom by delivery pump, flows into from the sharp side of cutter section 2 by pipe main body 1, and mud entered cutter section 2 and is split into 4 entrances and enters respectively in boiler as shown in the arrow in figure.The existence of cutter section 2 can significantly not increase the resistance that mud is carried, and therefore, can not make a significant impact the flow of sludge delivery pump, and improve mud shunting diffusivity.Operational excellence in actual engineering operation.
Embodiment:
By application of installation of the present invention in certain pharmaceutical factory's biochemical sludge fluidized combustion engineering.In this engineering, the water content of mud is 70%～80%, burning amount is 100 tons/day, before not installing apparatus of the present invention additional, wet mud is delivered directly to fluidized-bed combustion boiler in sludge bin through sludge pump and burns, and sludge carrier pipe road diameter is Φ 219 × 7, because bulk mud directly enters in fluid bed, owing to not spreading out in time, low temperature sludge may directly contact high temperature blast cap, causes the frequent chilling of blast cap to quench and damages.Within the time of half a year, multiple blast caps damage, and have caused 2 blowing outs maintenance.This device is welded on to the bottom of raw sewage pipeline, mud enters before boiler, and mud is split into 4 parts rapidly through cutter tangent plane, and the mud that enters burner hearth is effectively disperseed, and enters after burner hearth anhydration and incineration rapidly, the possibility of also having avoided mud to sink to the bottom.In half a year after installation apparatus of the present invention, do not have similar fault and occur, incinerator normal operation.
