Abstract
The utility model relates to an enclosed energy-saving lime kiln, which is characterized in that a fire chamber (7) is in an oblong shape; at least four inner arches (5) are arranged in the fire chamber; the lower end of a hollow cone cylinder (4) above the fire chamber is small, and the upper end is large; a sealing cover (1) is arranged above the cone cylinder; a material inlet (2) and a plurality of smoke outlets (3) are arranged on the sealing cover. The utility model has the advantages of low cost of coal, high content of about 90 percent of lime calcium oxide produced by the enclosed energy-saving lime kiln, and low pollution source generated by burning a ton of coal. Thus, the enclosed energy-saving lime kiln has great significance to the development of coal and lime burning industry.
Description
Technical field
The utility model relates to a kind of closed energy-saving limestone kiln.
Background technology
At present, fire at lime and still to adopt the mode lime calcining of naked light kiln in the industry, its kiln body mainly is made up of arch, type fire storehouse, a garden and garden type kiln platform and the big hollow cone cylinder of a bite top handle in the outer arch, one.With this klining system generally be can burn in three to five days ripe, its advantage be put up a kiln simple.But shortcoming is can not scale, the producing of safety, can't be energy-conservation, ecotope is caused severe contamination.
Summary of the invention
The purpose of this utility model provides the closed energy-saving limestone kiln that a kind of energy-conservation, quality product improves, reduces environmental pollution.
The technical solution of the utility model is: the structure in closed energy-saving limestone kiln is: fiery storehouse is three-dimensional rectangle, in fiery storehouse, be provided with arch at least four, the hollow cone cylinder of top, fire storehouse is that little upper end, lower end is big, there is sealing cover awl cylinder top, sealing cover becomes with strip calcium barnacle, and sealing cover is provided with feeding mouth and a plurality of venthole.The transverse width in fire storehouse is 0.9～1.1 meter, and longitudinal length is 1.9～2.1 meters, and is high 0.7～0.8 meter.
Energy-saving lime kiln characteristics of the present utility model are: 1, increase to several by a single arch, its objective is and can (every kiln) produce product and the kiln phenomenon that do not occur collapsing (every kiln can go out about 150 tons of products) in a large number; 2, dwindle Huo Cang (about 3 to 4 meters of traditional round fiery storehouse diameter), dwindle the bottom of hollow cone cylinder and increase the top and can enlarge between the calcium stone incendiary space mutually; 3, by increasing the vertical sealing cover of kiln body, the flue dust that heat energy and heat energy produced that enables to utilize utilizes once more, thereby reaches the loss of maximum control heat energy and the generation of pollution.
Energy-saving lime kiln of the present utility model is compared with the prior art: 1, one ton of lime of the every production of traditional kiln, need coal-fired cost at 180 yuan, and energy-saving lime kiln of the present utility model is produced one ton of lime, only needs 130 yuan coal-fired cost; 2, the calcium-oxide content of traditional kiln production is about 80%, and the calcium-oxide content of energy-saving lime kiln production of the present utility model is about 90%; 3, one ton of source of pollution that coal produces of the every burning of traditional kiln are 40,000 milligrams, and one ton of coal produced pollution of the every burning of energy-saving lime kiln of the present utility model source is 20,000 milligrams.Therefore the invention of energy-saving lime kiln of the present utility model will be significant to there being bituminous coal lime to fire the development of industry.
Description of drawings
Fig. 1 is an energy-saving lime kiln structural representation of the present utility model;
Fig. 2 is energy-saving lime kiln A-A of the present utility model (part) cut-away view;
Among the figure, 1-sealing cover, 2-opening for feed, 3-ventilation opening, arch in the 4-hollow cone cylinder, 5-, 6-fire storehouse, 7-kiln platform, 8-fire box.
Embodiment
As shown in the figure, the fiery storehouse 6 of energy-saving lime kiln of the present utility model is three-dimensional rectangle, and the transverse width in fiery storehouse is about 1 meter, and longitudinal length is about 2 meters, highly about 0.8 meter.Be provided with in six in fiery storehouse and encircle 5, the distance between arch and the arch is about 15 centimetres.The hollow cone cylinder 4 of top, fire storehouse, big for little upper end, lower end, about 3 meters of lower end diameter is bored cylinder and is placed on the kiln platform 7.There is sealing cover 1 awl cylinder top, and sealing cover is diluted to the mud shape with brick one-tenth or lime and sticks with paste, and sealing cover is provided with feeding mouth 2 and a plurality of venthole 3 (a plurality of distributions on circumference).
Sintering procedure, put into required calcium stone from feeding mouth after, seal feeding mouth with cover plate, in the fire box of fiery storehouse, stack raw coal, seal fire door after, can light and fire, burn when calcium stone sends dazzling white light, promptly finish and fire.
Claims (3)
1. closed energy-saving limestone kiln, it is characterized in that fiery storehouse (7) is rectangular parallelepiped, in fiery storehouse, be provided with arch (5) at least four, the hollow cone cylinder (4) of top, fire storehouse is that little upper end, lower end is big, awl cylinder top has sealing cover (1), sealing cover to be provided with feeding mouth (2) and a plurality of venthole (3).
2. closed energy-saving according to claim 1 limestone kiln, the transverse width that it is characterized in that fiery storehouse is 0.9～1.1 meter, longitudinal length is 1.9～2.1 meters, and is high 0.7～0.8 meter.
