Description
Technical field
The utility model belongs to electric cleaner technical field, is specifically related to the flexible flap dust collecting structure of a kind of labyrinth type.
Background technology
Metallurgy, electric power and other industrial furnace produce a large amount of exhaust gas dusts in production run process.At present, the removal of industrial smoke dust utilizes (dry type or wet type) electric cleaner equipment to realize in a large number.Existing electric cleaner to the arresting efficiency of dust up to 99.9%, but at Electric Field in ESP in exhaust gas dust trapping process, dry electric precipitation device can flee from electric field because the reasons such as vibration dust-cleaning, flue gas stream cause dust secondary fly-up, part also can not fled from electric field by the Charged that electric field traps in time simultaneously, discharged by deduster air outlet, thus cause dust-collecting efficiency not improve.
For wet electrical dust precipitator, spray spout sprays a large amount of atomized drop, and drop is after dust is combined in flue gas, and major part can be trapped by electric field.The drop do not trapped by electric field and exhaust gas dust finally flee from electric field, discharged, cause dust-collecting efficiency to improve by deduster air outlet, and outlet water smoke also can be caused to drip content overproof simultaneously.
Existing cleaner is head it off, except adopting methods such as optimizing rapping, flow field, water spray and electric field, can arrange trough plate structure, for collecting escape dust in air outlet.But general trough plate structure is simple, rearranged by " U " shape troughing plate, although portion collection effect can be played, for the secondary fly-up or spray water mist avoiding collected dust is escaped, trough plate does not establish rapping or spray equipment, its dust or drop collection efficiency lower.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model there are provided the flexible flap dust collecting structure of a kind of labyrinth type, improves tradition (dry type or wet type) electric cleaner dust-collecting efficiency.
For achieving the above object, the utility model adopts following technical scheme:
The flexible flap dust collecting structure of a kind of labyrinth type, be arranged on the outlet of last electric field of electric cleaner 1 or be arranged in the air outlet 3 of electric cleaner 1, the flexible flap dust arrester installation 2 of described labyrinth type comprises driving wheel 4, driven pulley 9, flexible flap 7 is connected to driving wheel 4, on driven pulley 9, driving wheel 4 is connected with motor reducer 5, driven pulley 9 is immersed in tank 12, flooding nozzle 11 and lower flooding nozzle 13 is furnished with in tank 12, the sewage draining exit of tank 12 is connected with sedimentation basin 14, the supernatant outlet on sedimentation basin 14 top is connected with modified pond 15 entrance, modified pond 15 is exported and is connected by flushing pump 16 water supplement port of pipeline with tank 12.
The surface uniform of described flexible flap 7 outputs hole 8, and the hole 8 of the flexible flap 7 of adjacent two layers adopts misalignment effects, make flue gas by time form labyrinth structure, the dust of electric field of escaping out or drop are by being captured down with the collision of flexible flap 7.
Described driving wheel 4, driven pulley 9 Surface Machining decorative pattern 10.
Olive shape is formed outside described driving wheel 4, driven pulley 9.
Described flexible flap 7 sidepiece is provided with directive wheel 6.
Described upper flooding nozzle 11, lower flooding nozzle 13 are strong flushing nozzle.
The beneficial effects of the utility model: the utility model significantly improves the secondary arresting efficiency of Electric Field in ESP exit escape dust, thus the overall dust-collecting efficiency improving tradition (dry type or wet type) electric cleaner.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the flexible flap dust collecting structure of a kind of labyrinth type, be arranged on the outlet of last electric field of electric cleaner 1 or be arranged in the air outlet 3 of electric cleaner 1, for the built equipment that puts into operation, by installation after the transformation to air outlet 3 shell and supporting construction, this device is for improving the overall dust-collecting efficiency of tradition (dry type or wet type) electric cleaner 1, the flexible flap dust arrester installation 2 of described labyrinth type comprises driving wheel 4, driven pulley 9, flexible flap 7 is connected to driving wheel 4, on driven pulley 9, driving wheel 4 is connected with motor reducer 5, utilize motor reducer 5 as power source, under driving wheel 4 with the effect of driven pulley 9, drive flexible flap 7 to rotate, driven pulley 9 is immersed in tank 12, flooding nozzle 11 and lower flooding nozzle 13 is furnished with in tank 12, the sewage draining exit of tank 12 is connected with sedimentation basin 14, the supernatant outlet on sedimentation basin 14 top is connected with modified pond 15 entrance, modified pond 15 is exported and is connected by flushing pump 16 water supplement port of pipeline with tank 12.
The surface uniform of described flexible flap 7 outputs hole 8, and the hole 8 of the flexible flap 7 of adjacent two layers adopts misalignment effects, make flue gas by time form labyrinth structure, the dust of electric field of escaping out or drop are by being captured down with the collision of flexible flap 7.
