The industry such as Iron And Steel Industry, calcium carbide industry, aluminum oxide industry, refractory materials are all lime consumption rich anies influential family.The industry that nearly 2 years these industries are all high speed developments, annual output is substantially all with more than 20% speed increment, but their need main raw, subsidiary material--lime does not really have corresponding growth, so caused the anxiety of lime, thereby irritated starting in a large number of social native limestone kiln, the severe contamination having caused again environment in full flourish of native firing.In this case, country and local government have put into effect policy and the rules of the native firing of a series of regulations in succession, but are difficult to realize desired result, and reason is to have irritating of demand.Therefore wanting to infuse the end administers the pollution of native firing, must carry out the problem that demand is solved in Modern New Technology limestone kiln.
So-called Modern New Technology limestone kiln is exactly to have environmental protection, power saving function and mechanize, modernization limestone kiln that level of automation is higher.But existing limestone kiln exists and yields poorly, especially, in the situation that adopting low-heat value gas, single kiln output can not break through 500 tons of day output.
Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of novel many fuel rings beam-type limekiln, to overcome described defect of the prior art.
[summary of the invention]
For addressing the above problem, the object of the present invention is to provide many fuel rings beam-type limekiln that a kind of calcination efficiency is high, calcining is even, can effectively improve single kiln day output, take and solve existing limestone kiln and adopt in the situation that low-heat value gas is fuel calcination efficiency low, the problem that day output is low.
For achieving the above object, the technical scheme that the present invention takes is: a kind of many fuel rings beam-type limekiln, the inner core that it comprises kiln shell and is positioned at kiln shell; Between described kiln shell and inner core, form an annular burning district; In described annular burning district, be provided with upper strata burning beam and lower floor's burning beam, this upper strata burning beam and lower floor's burning beam go to upper and lower two rows and are interspersed; Described upper strata burning beam and lower floor's burning beam extend in inner core through edge, annular burning district from the sidewall of kiln shell respectively; Stretch on the upper strata burning beam in annular burning district and lower floor's burning beam and be respectively arranged with some burners.
Many fuel rings beam-type limekiln of the present invention is further set to: extend outside kiln shell the end of described upper strata burning beam and lower floor's burning beam, and forming respectively a upper strata beam stationary platen He Yi lower floor beam stationary platen, this upper strata beam stationary platen is connected with kiln shell by fastening piece with lower floor beam stationary platen.
Many fuel rings beam-type limekiln of the present invention is further set to: the top of described kiln shell is provided with a hopper, and the below of hopper is provided with a bell; Described hopper and material loading guide rail docking are provided with feeding cart on described material loading guide rail; This material loading guide rail extends to the bottom in limestone kiln.
Many fuel rings beam-type limekiln of the present invention is further set to: the bottom of described kiln shell is provided with an ash discharging gear and a storage ash bucket; In the bottom of described storage ash bucket, be provided with a vibration ash hoist.
Many fuel rings beam-type limekiln of the present invention is also set to: on described upper strata burning beam and lower floor's burning beam, be connected with combustion-supporting gas pipeline and gas pipeline.
Compared with prior art, the present invention has following beneficial effect:
1. the calcining penetration power of many fuel rings beam-type limekiln of the present invention is strong, and evenly, calcining zone and preheating zone are longer, can effectively reduce product hear rate, significantly improve the quality of products in calcining;
2. the nozzle of many fuel rings beam-type limekiln of the present invention is positioned at annular burning district, its flame and high-temperature gas directly spray to and are positioned at the material bed of annular burning district, below, High Temperature Gas physical efficiency after burning is uniformly distributed in kiln, there is not gas flow dead angle, therefore also eliminate calcining dead angle, and then improved calcining uniformity coefficient;
3. many fuel rings beam-type limekiln of the present invention can significantly improve Wingdale capacity by strengthening the width of annular calcining zone, thereby improve the day output of calcining kiln, its its day output list kiln can reach more than 800 tons, economic benefit is very outstanding.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of many fuel rings beam-type limekiln of the present invention.
Fig. 2 is along the sectional view of A-A in Fig. 1.
Fig. 3 is along the sectional view of B-B in Fig. 1.
[embodiment]
Refer to Figure of description 1 to shown in accompanying drawing 3, the present invention is a kind of many fuel rings beam-type limekiln, and it is mainly comprised of kiln shell 1 and two portions such as inner core 2 of being positioned at kiln shell 1.
Wherein, between described kiln shell 1 and inner core 2, form an annular burning district 3, in this annular burning district 3, take in Wingdale 6, and Wingdale 6 is calcined.In described annular burning district 3, be provided with upper strata burning beam 4 and lower floor's burning beam 5, this upper strata burning beam 4 and lower floor's burning beam 5 go to upper and lower two rows and are interspersed.Described upper strata burning beam 4 and lower floor's burning beam 5 respectively from the sidewall of kiln shell 1 through annular burning district 3 along extending in inner core 2.Stretch on the upper strata burning beam 4 in annular burning district 3 and lower floor's burning beam 5 and be respectively arranged with some burners (not shown).
Further, described upper strata burning beam 4 and the applicable pluralities of fuel of lower floor's burning beam 5 are produced, as coal dust, coal gas, heavy oil etc.Extend outside kiln shell 1 end of described upper strata burning beam 4 and lower floor's burning beam 5, and form respectively upper strata beam stationary platen 7 He Yi lower floor beam stationary platens 8, and this upper strata beam stationary platen 7 is connected with kiln shell 1 by fastening piece with lower floor beam stationary platen 8.On described upper strata burning beam 4 and lower floor's burning beam 5, be connected with combustion-supporting gas pipeline 17 and gas pipeline 18.
The top of described kiln shell 1 is provided with a hopper 9, and the below of hopper 9 is provided with a bell 10; Described hopper 9 and material loading guide rail 11 docking are provided with feeding cart 12 on described material loading guide rail 11; This material loading guide rail 11 extends to the bottom in limestone kiln.Qualified Wingdale raw material unloads material bin 9 by feeding cart 12 by material loading guide rail 11, and evenly pours annular burning district 3 into by bell 10.
