Abstract

The utility model relates to an effective coal dust deduster with self block eliminator. Coal dust dredging rings (5) are arranged on the inner walls of a primary processor (1) and a secondary processor (2); a coal dust stirrer (6) rotating along an inner chamber axle center line and a net-shaped bottom plate (7) are arranged in the secondary processor (2). The utility model plays a function of preventing coal dust from escaping along the inner wall of a processor by installing coal dust dredging rings in the two processors, and causes the coal dust to obtain concentrated processing. The stirring device is arranged in the secondary processor and the net-shaped bottom plate is matched for stacking soil and ceramic filling materials, which causes the utility model to be capable of dredging blockage by stirring and enlarging spray under the condition of coal dust detention.

Description

Self block eliminator efficient fuel coal smoke dust collector

[technical field] the utility model belongs to the smoke treatment device technical field of structures.

[background technology] existing smoke treatment device in particular for the fountain processor to coal smoke, mainly is water film dedusting, bag-type dust and electrostatic precipitation, and water film dedusting is owing to be to only depend on water that flue dust is washed, and dust removing effects is very undesirable; Bag-type dust needs a large amount of cloth bags and cloth bag is carried out brute force bleed, and the cloth bag waste is big in the short time, and electric weight expends also big, and the dedusting cost is too high; And electrostatic precipitation relies on power consumption fully, and the dedusting cost is also very high.At present, the mode that also has employing to place filler in deduster is carried out dedusting, but because after equipment moved a period of time, most of flue dust is not absorbed to be taken away by current, is jammed in the filler, causes flue gas to pass through.Flue dust is also because the straight barrel type shape of processor inwall makes that under the effect of edge air-flow principle flue dust is along rising on the barrel edge, causes flue dust to escape along wall and can't handle.

[summary of the invention] the purpose of this utility model provides a kind of flue dust easily to be taken away by shower water for the weak point that overcomes above-mentioned prior art existence just, filling adsorption is strong, the flue dust air-flow flows in processor easily, can effectively solve the self block eliminator efficient fuel coal smoke dust collector of obstruction.

The purpose of this utility model is achieved by the following technical solution.

This self block eliminator efficient fuel coal smoke dust collector is that primary processor and secondary processor inwall are provided with flue dust and dredge ring, is provided with in secondary processor along the flue dust agitator and the netted base plate of the rotation of inner chamber axial line.

The flue dust agitator is made up of transmission device, axis and puddler; The netted base plate of secondary processor is provided with the filler with granular native Tao Zuowei.

The utility model is dredged ring and has been played the effect that prevents that flue dust from escaping along the processor inwall by flue dust is set in the bi-level treatment device, and flue dust is focused on.Because the delay of flue dust results in blockage easily, and agitating device is set in secondary processor, and be equipped with netted base plate and stack native pottery filler, make it under the situation that flue dust is detained, can dredge obstruction by stirring and strengthen to spray.

Further set forth the utility model content below in conjunction with Figure of description and embodiment.

[description of drawings] Fig. 1 is the utility model structural representation.

The industrial products that [specific embodiment] primary processor 1 of the present utility model and secondary processor 2 had both been formed by the sheet metal assembly welding, also can directly adopt brick in soot emissions place, cement structures builds up, sprinkler head 3 is located in the primary processor 1 and is communicated with outer water tube, asbestos yarn 11 is many and hangs from above sprinkler head 3 times around whole primary processor inner chamber, flue dust is dredged the inner chamber top and bottom that ring 5 is separately positioned on processor, the section type shape that its flue dust is dredged ring 5 can be multiple moulding, general common is rectangle or triangle, tube connector 4 is the conveyance conduits that the processing flue dust of primary processor 1 are transported to secondary processor 2, be provided with sprinkler head 17 in the secondary processor 2, powerful sprinkler head 23 and dewatering plate 16, flue dust is dredged ring 5 and equally also is arranged on secondary processor 2 inner chambers by upper-lower position, near on flue dust dredge ring 5 lower end and also be provided with flue dust agitator 6, this agitator is by transmission device 8, axis 9 and puddler 10 are formed, and axis 9 places on the bearing block 20; Filler 12 is the lighter potter's clay particle of proportion, and it is deposited on the netted base plate 7, and the thickness of heap is decided by the difference of flue dust kind, and it stacks thickness can be thick in whole agitator 6 is flooded.Upper and lower side at secondary processor 2 also is respectively equipped with air gauge 13,14, negative pressure state whether occurs in the space in order to observation post.

Working method of the present utility model is: flue dust gas enters primary processor 1 from import 21, dredge the effect of ring 5 during rising owing to flue dust, flue dust is risen by central authorities, and can't escape along barrel, some asbestos yarns 11 through hanging from above when central authorities rise in the tube chamber, the moisture film that is produced under the spray effect of sprinkler head 3 make the abundant melt water of flue gas of coarse grain flue dust and strong adhesion and are taken away through row's mouth 26 by current.The flue dust gas of handling through primary processor 1 flows into secondary processor 2 via tube connector 4, flue gas is still dredged ring 5 processing after tube central authorities rise through flue dust in secondary processor, fully contact with potter's clay granular filler 12 through netted base plate 7, sprinkler head 17 is with misty rain shape spray irrigation filler, make filler drenched and fully and the flue gas contact-impact make flue dust be detained to get off, wherein part is dashed by current, flows into circulating sedimentation tank, and clarification is used to resupply spray.Last flue dust gas forms the national specified discharge standard gas that meets up to standard after the I and II processor processing, discharged by air exhauster 22 suctions through delivery pipe 25.The filler 12 that soil is made pottery and done is generally chosen profile for circular, and diameter is approximately 10-35mm, and about every cubic metre of 250-300kg, its proportion is lighter, can float on the surface, and corrosion resistant, heatproof, intensity suit, and there is micropore on the surface, and absorption affinity is strong, and cheap.For being deposited in the filler space, the flue dust that prevents to handle results in blockage, epimere and hypomere at secondary processor are respectively arranged with air gauge 13,14, stop up in case produce, then the upper and lower pressure reduction of air gauge strengthens, pressure-sensitive pipe starts power supply 19 automatically makes flue dust agitator 6 rotate and open powerful shower water shower nozzle 23 and clean, make delay flue dust and water mix the back and sink, flow to circulating sedimentation tank through row's mouth 27.Access hole 24 is exclusively used in use is overhauled in processor inside.
