The utility model discloses a novel energy-saving lime kiln, which relates to an improvement on the lime kiln. The novel energy-saving lime kiln comprises a kiln body (11), an expansion tank (14), a pump set (15) and an oil storage tank (18), wherein the oil storage tank (18) and the expansion tank (14) are connected into the kiln body (11) through an oil inlet pipeline and an oil returning pipeline; the pump set (15) is installed on the oil inlet pipeline; the novel energy-saving lime kiln is characterized by further comprising a radiator (16); and the radiator (16) is installed on the oil inlet pipeline. The novel energy-saving lime kiln solves the problem that the heat efficiency of the conventional lime kiln is low, and has the advantage of high heat efficiency; the heat consuming index is lower than 860kcal/kg; and the novel energy-saving lime kiln is an ideal kiln with an excellent environment-friendly index.
Description
Technical field
The utility model relates to the improvement technology in limestone kiln.
Background technology
The limestone kiln is an equipment of producing lime, and the popular limestone kiln mainly contains basic kiln type such as earth kiln, power-saving kiln, mechanical vertical kiln (kiln is closed in Japanese river), beam-type limekiln (Italian Fu Kasi kiln), two thorax kiln (Switzerland's wheat Wurz kiln), sleeve kiln (German Bake Bach's kiln), rotary kiln on the domestic and international market at present.
Existing limestone kiln is generally designed aspect ratio and is no more than 6: 1, and the preheating zone is shorter, thus kiln top temperature about 300 ℃, one ton of waste gas that lime produced of every production is generally 1350m
3About, if this part heat adds warm air with interchanger, thermo-efficiency has only 30%.
The utility model content
The utility model provides a kind of novel energy-conserving limestone kiln, and the utility model has solved the low problem of thermo-efficiency that existing similar technology exists.
For addressing the above problem, the utility model adopts following technical scheme: comprise kiln body 11, expansion drum 14, pump group 15 and storage tank 18; Storage tank 18 and expansion drum 14 through advance, used oil pipe is connected in the kiln body 11, and pump group 15 wherein is installed on the in-line; Also comprise scatterer 16, scatterer 16 is installed on above-mentioned in-line.
The utlity model has the high advantage of thermo-efficiency.Heat consumption index can reach below the 860kcal/kg, is the good desirable kiln type of environmental protection index.
Description of drawings
Fig. 1 is the utility model structural representation.
Nomenclature among the figure: blower fan 1, sealing ash discharging gear 2, main induced draft fan 3, chimney 4, sack cleaner 5, pulverized coal feed pipe 6, servo hopper 7, spiral gauger 8, injector 9, divider 10, kiln body 11, distribution device 12, skew bridge 13, expansion drum 14, pump group 15, scatterer 16, oiling motor-mount pump 17, storage tank 18 from coal-making system.
Embodiment
As shown in Figure 1, a kind of novel energy-conserving limestone kiln comprises kiln body 11, expansion drum 14, pump group 15 and storage tank 18; Storage tank 18 and expansion drum 14 through advance, used oil pipe is connected in the kiln body 11, and pump group 15 wherein is installed on the in-line; Also comprise scatterer 16, scatterer 16 is installed on above-mentioned in-line.
The utility model technical characterstic:
1. the preheating zone prolongs technology
The aspect ratio of the utility model has reached 7: 1; General design aspect ratio is no more than 6: 1, and the utility model amplifies aspect ratio, for having reserved long preheating zone in the limestone kiln; The cold Wingdale of kiln is gone in the waste heat heat exchange that can make full use of useless flue gas, has improved thermo-efficiency.Adopt this design, omitted the heat exchanger that general limestone kiln need keep the outer flue gas of kiln,, make full use of in the preheating of kiln sodalime stone, greatly reduce heat energy consumption the waste heat behind the lime kilning.
General limestone kiln because the preheating zone is shorter, so kiln top temperature about 300 ℃, one ton of waste gas that lime produced of every production is generally 1350m
3About, if this part heat adds warm air with interchanger, thermo-efficiency has only 30%, and through prolonging the preheating zone, directly with the Wingdale heating, thermo-efficiency reached more than 60%, for this reason, the heat consumption index of ash per ton can reduce 3.99kgce/t.
2. adopt the beam type calcining technology
Its core is exactly the middle part in the limestone kiln, up and down several burning beams of staggered arrangement.Several burners of burning beam set inside are evenly distributed on the section in limestone kiln burner.Burner directly is sprayed onto fuel on the section of limestone kiln and calcines, and has guaranteed that whole limestone kiln section can be by even heating, realize the stable of lime quality index.Simultaneously, because in when design, just confirmed the position of calcining zone according to the situation of raw material and fuel, so beam-type limekiln the calcining zone drifting problem can not take place.
The beam type calcining technology is in the world one of advanced lime calcining technology, and the burning beam of the utility model adopts the novel type of cooling, both guaranteed the stable of calcining zone with evenly, realized the waste heat recovery of cooling oil again.This technology fully reclaims the waste heat of thermal oil, has improved the thermo-efficiency in limestone kiln, can reduce hear rate 7.1kgce/t.
3. novel seal goes out gray technology
This kiln adopts the novel seal ash discharge, can guarantee the sealing effectiveness of ash discharge, can guarantee strict control ash discharge temperature again.Through cooling air lime thoroughly is cooled to below 80 ℃, is guaranteeing to have reduced heat waste under the lime handling equipment prerequisite in normal work-ing life.This technology can reduce general high temperature ash discharge limestone kiln hear rate 1.4kgce/t.
4. heat recovery technology
The thermal oil scatterer of general beam-type limekiln in the atmosphere that heat is all dispelled through cooling fan, has caused unnecessary heat waste, and the utility model has adopted a kind of new waste heat recovery new radiator.This scatterer at first carries out heat exchange with combustion air to thermal oil, and heated combustion air gets into the limestone kiln and participates in burning, and remaining heat just with the cooling fan cooling, has improved the overall thermal efficient in limestone kiln.
5. the monotubular kiln type of simplifying
The utility model belongs to the monotubular kiln, and the kiln tube can be for circular, rectangle and accurate orthogonal form, and is simple in structure.This kiln type does not have shaped brick, can use the standard square on the market fully, has practiced thrift investment, has simplified the expense of building by laying bricks or stones, has prolonged the work-ing life of anti-material.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
