Description

A kind of active carbon feedway

Technical field

The utility model relates to flue gas purifying equipment field, refers to a kind of active carbon feedway especially.

Background technology

Current, increasing rubbish has become the hang-up of urban development, and waste incineration and generating electricity is used widely as the processing method of a kind of innoxious, minimizing and resource.But, produce a lot of hazardous and noxious substances during incineration firing, as HCL, SO2, bioxin etc., must be processed by supporting flue gas purification system, prevent from causing gross pollution to environment.Remove bioxin and heavy metal, current mainstream technology is that the flue between reactor and bag dust collector sprays into active carbon and adsorbs it, then removes together with dust in bag dust collector.Therefore active carbon can evenly, continuous print adds conveying, be to realize the key that Dui bioxin and heavy metals emission control.

Because the consumption of active carbon is little, generally look garbage burning factory treatment scale at 5 ~ 15Kg/h(fixed), active carbon light specific gravity fine size simultaneously, therefore the feed conveying of active carbon is all the time all a difficult problem of flue gas purification system.

The addition method before adopted mainly contains following two kinds:

1) direct mechanical conveying adds.By special feeder (as conveyor screw or disk feeder), active carbon is added in flue, the method shortcoming is that fed distance is short, can only active carbon storehouse be placed on above flue, position limitation is large, simultaneously because flue negative pressure is large, very large suction is had, so feeding coal difficulty controls to feed.

2) Geldart-D particle adds.The active carbon got off by feeder by roots blower or pressurized air delivers to flue, and the method fed distance is far away, and to the not requirement of active carbon bin location, shortcoming is that blanking position is in malleation, and active carbon is easily revealed, and pollutes external environment condition, and feeding coal is also difficult to control.

Utility model content

The utility model proposes a kind of active carbon feedway, solve feed heavy handled problem in prior art.

The technical solution of the utility model is achieved in that a kind of active carbon feedway, comprise: active carbon storehouse, feeder and jetting system, described feeder is positioned at below described active carbon storehouse, and pass through pipeline communication, described jetting system to be positioned at below described feeder and to pass through pipeline communication, shutoff valve is provided with between described active carbon storehouse and described feeder, described jetting system comprises venturi-type eductors and is positioned at the roots blower at described venturi-type eductors rear, be communicated with described feeder above described venturi-type eductors, front is communicated with reaction flue, thus active carbon is through described active carbon storehouse, described feeder, injectedly after described jetting system enter flue.

Further, above described active carbon storehouse, be fixed with roof scrubber, excessive and contaminated environment when preventing active carbon material loading.

Further, described feeder is screw feeder or disk feeder.

Further, space is left in described venturi-type eductors and described feeder junction.

Further, described venturi-type eductors comprises the conical jet pipe, delivery pipe and the feed pipe that are positioned at inside, described delivery pipe is between described jet pipe and reaction flue, and the cross-section structure of then taper diastole is shunk in first taper, described feed pipe is positioned at above described venturi-type eductors, distance L between the front end of described jet pipe and described delivery pipe is 20mm, and now emitted dose is maximum.

Further, the mouth of pipe wind speed Vi=0.5 ~ 0.6 times velocity of sound of described jet pipe, now the mixture ratio of active carbon and air is maximum.

Active carbon, by adopting the improvement of venturi-type eductors and corresponding structure and annexation, sprays and enters into flue by described active carbon feedway of the present utility model easily.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the connection structure schematic diagram of a kind of active carbon feedway of the utility model embodiment;

The structural representation of the civilian mound eductor that Fig. 2 is the feedway of active carbon shown in Fig. 1.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As depicted in figs. 1 and 2, a kind of active carbon feedway, comprise: active carbon storehouse 1, feeder 3 and jetting system, feed seat in the plane 3 is below active carbon storehouse 1, and pass through pipeline communication, jetting system to be positioned at below feeder 3 and to pass through pipeline communication, shutoff valve 2 is provided with between active carbon storehouse 1 and feeder 3, jetting system comprises venturi-type eductors 4 and is positioned at the roots blower 5 at venturi-type eductors 4 rear, be communicated with feeder 3 above venturi-type eductors 4, front is communicated with reaction flue 6, thus active carbon is through active carbon storehouse, feeder 1, injectedly after jetting system enter flue 6.

Further, above active carbon storehouse 1, be fixed with roof scrubber 7, excessive and contaminated environment when preventing active carbon material loading.

Further, feeder 3 is screw feeder or disk feeder.

Further, space is left in venturi-type eductors 4 and feeder junction.

Further, venturi-type eductors 4 comprises the conical jet pipe 41, delivery pipe 42 and the feed pipe 43 that are positioned at inside, delivery pipe 42 is between jet pipe 41 and reaction flue 6, and the cross-section structure of then taper diastole is shunk in first taper, feed pipe 43 is positioned at above venturi-type eductors 4, distance L between the front end of jet pipe 41 and delivery pipe 42 is 20mm, and now emitted dose is maximum.

Further, the mouth of pipe wind speed Vi=0.5 ~ 0.6 times velocity of sound of jet pipe 41, now the mixture ratio of active carbon and air is maximum.

Active carbon feedway of the present utility model have employed feed and carries the design be separated, active carbon in active carbon storehouse 1 is after feeder 3 is quantitatively discharged, space is left between feeder 3 and jetting system, during injection, the negative pressure that feed pipe place produces due to airstream and by extraneous air inspiration, better convey materials, solve and carry due to malleation in the past, negative pressure affects the difficult problem that operational throughput controls, this apparatus structure order, do not need to adopt special material, process easy, convey materials speed is fast, continuity is good, in disperse state, be convenient to the absorption of follow-up bioxin and heavy metal.

In addition, this active carbon feedway can also be applicable to the conveying of material of other light specific gravities, fine size.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
