Description
Technical field
The utility model relates to a kind of glass kiln waste heat boiler that has shot-cleaning mechanism, belong to the boiler technology field.
Background technology
In the prior art, glass kiln production line (float glass) comes melting glass by combustion of liquid or gaseous fuel, have the compositions such as alkali metal in the frit behind the flue gas process production line that burning produces, and sulfur content is higher in the flue gas, flue dust has stronger corrosivity, cementability.The characteristic of flue dust is that density is little, thin and light, bonding capacity is good, high adsorption capacity, unsuitable sedimentation between Electrostatic Absorption and particulate, contain multiple alkali metal particulates such as SiO2, MgO, CaO, Fe2O3, Al2O3, P2O3, Na2O, TiO, K2O in the ash, these particulates present the different junction characteristics of being stained with under different cigarette warm areas, flue gas sulphur content and wetness action.Have a strong impact on the recycling of glass kiln fume afterheat, glass kiln waste heat boiler does not search out a kind of reliably economic ash removal method so far, how to remove dust stratification on the heating surface effectively continuously and be the key point that such waste heat boiler can stable operation.As far as we know, such waste heat boiler was tested following multiple dedusting method at present:
1, dust collection by sound wave:
To the sound wave of heating surface space input certain frequency, with stronger disturbance, reach the effect of removing fouling of heating surface at set intervals to flue gas stream.Its shortcoming is: deashing continuously, and very big in the different parts dust removing effects difference of heating surface, there are a lot of blind areas, and, can bring a large amount of cold airs into during the input sound wave because the boiler negative pressure is bigger, had a strong impact on the thermal efficiency of boiler; The heating surface of different parts differs greatly because of the applied stress value that vibration causes, its anti-fatigue life difference.
2, compressed air or high steam purge dedusting:
Purge to heating surface space input compressed air or high steam at set intervals, reach the effect of removing fouling of heating surface.Its shortcoming is: deashing continuously, and very big in the different parts dust removing effects difference of heating surface, there are a lot of blind areas; Import a large amount of cold air or steam, had a strong impact on the thermal efficiency of boiler; The active force that wind at a high speed or steam have compacting to compress to the above-mentioned grey type of pressing close to tube wall; Especially steam can not use, water vapour bring the junction characteristic of being stained with that will increase this class ash greatly into, the ash that makes moist will have a strong impact on the dust collection effect of low-temperature space; A large amount of compressed air or steam will consume a large amount of energy, and will be very uneconomical.
3, explosion, shock wave dedusting:
Its principle and dust collection by sound wave are similar, and just the explosive combustion with a certain amount of fuel produces outburst shock wave replacement sound wave, has above-mentioned shortcoming equally, and the difficult control of explosive force, and local heating's face easily is damaged.
4, mechanical vibrator dedusting:
Its operation principle is: periodically impact the bar that shakes that closely contacts with heating surface by beater, make the heating surface tube group form body vibration, and the vibrating machine ripple along the heating surface pipe transfers to each geometric point, thereby reach the dedusting purpose.Its advantage be mechanical wave generation, be delivered on time and the Spatial Dimension and be evenly distributed, spread the ash of class for big particulate, pine, as the cement dust in the kiln heat recovery boiler, has extremely good dust removing effects, be extensive use of, shortcoming is that high adsorption capacity, unsuitable such dust ash-removal effect of sedimentation between, Electrostatic Absorption good to nanoscale, bonding capacity and particulate is poor.
5, water jetting dedusting:
Its operation principle is: water is directly injected on the boiler heating surface, the principle of water flushing, this method has certain effect, but a lot of shortcomings are arranged: water is seriously polluted, boiler is wanted frequent blowing out, the cold and hot destruction of boiler is serious, boiler corrosion increases the weight of, in a word, this is a kind of method that is not able to.
6, complex method dedusting:
Its operation principle is: adopt above-mentioned dust collection method more than 2 kinds or 2 kinds simultaneously on a cover glass kiln waste heat boiler.
This method, system complex, investment, maintenance cost are big, and ash-removal effect is also very undesirable.
Summary of the invention
