Description
Technical field
What the present invention relates to is a kind of glass kiln waste heat boiler that has shot-cleaning mechanism, belongs 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
The objective of the invention is to overcome the deficiency that prior art exists, and provide a kind of steel ball that utilizes to fall to impacting the waste heat boiler of shot-cleaning type glass kiln that waste heat boiler heating surface carries out dedusting, this boiler can be removed the dust on the heating surface continuous, stable, effective, economical, reliably, make waste heat boiler, especially at glass kiln waste heat boiler can safety, reliably, economically the operation, can carry forward vigorously of the application of glass kiln waste heat boiler, advance glass kiln melting industry energy-saving emission-reduction technology revolutionaryly at glass production industry (especially float glass furnace).
The objective of the invention is to finish by following technical solution, it is mainly by boiler heating surface, boiler smoke passage and dust-removing device for boiler are formed, described dust-removing device for boiler is a kind of shot-cleaning device, and it is included in that install the top of waste heat boiler heating surface, at least onely can evenly sow steel ball on the waste heat boiler heating surface and produce the steel ball sowing mechanism of the effect that impacts; One is installed in and is used to collect the steel ball collecting mechanism that impacts to fall behind the waste heat boiler heating surface below the waste heat boiler heating surface; One is that link to each other with the steel ball collecting mechanism and the steel ball after collecting can be promoted to the in-house steel ball of steel ball sowing transport establishment continuously.
