Description
Technical field
The utility model relates to a kind of two thorax heat accumulating type lime shaft kiln smoke pre-heating and recovery channel structure, belongs to two thorax heat accumulating type lime shaft kiln technical fields.
Background technology
Two thorax heat accumulating type lime shaft kilns are widely used in industrial circle.Two thorax lime shaft kilns have two kiln thoraxes, kiln thorax burning when work, and another kiln thorax uses as chimney, two kiln thorax alternate combustion, at interval of a period of time, as 15 minutes, commutation was once.In two thorax heat accumulating type lime shaft kilns, flue gas is guided to deduster from Yao Ding, and combustion air is delivered to kiln top from Ventilator Room, and flue gas, the combustion air pipeline on kiln top share.Combustion air enters kiln thorax, kiln top flue gas is discharged and taken one's place to flashboard control by kiln from kiln thorax, and kiln is taken one's place to the every commutation of valve plate once, and burning kiln thorax and the kiln thorax that do not burn exchange once.In the time of No. 1 kiln thorax burning, connecting No. 1 kiln thorax side pipe road is combustion air, and connecting No. 2 kiln thorax side pipe roads is flue gases; In the time of No. 2 kiln thorax burnings, connecting No. 2 kiln thorax side pipe roads is combustion airs, and connecting No. 1 kiln thorax side pipe road is flue gas, and each circulation change once.Because the calcining principle of two thorax heat accumulating type lime shaft kilns is two kiln thorax alternate combustion, can utilize this calcination characteristics recovered flue gas heat.
The flue gas of two thorax heat accumulating type lime shaft kilns of China and countries in the world and the pipeline path that combustion air is walked are all fixed at present, no matter how two kiln thoraxes convert, what what flue passed through all the time is flue gas, combustion air pipeline passed through all the time is combustion air, does not change with the conversion of kiln thorax.This structure makes to scatter and disappear in a large number by the heat of flue, and heat cannot be absorbed, and even burns out dust-collecting bag, necessary improvement because flue-gas temperature is too high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of two thorax heat accumulating type lime shaft kiln flue gas heat exchanging pipe, and this flue gas heat exchanging pipe can absorb the heat in flue gas better, saves the energy, increases economic efficiency and environmental protection more.
The technical scheme solving the problems of the technologies described above is:
A kind of two thorax heat accumulating type lime shaft kiln flue gas heat exchanging pipe, it comprises chimney, flue gas diffuses flashboard, two burning commutation flashboards, connect kiln thorax pipeline No. 1, connect kiln thorax pipeline No. 2, flue gas diffuses flashboard and is connected with two burning commutation flashboards respectively, two burning commutation flashboards respectively be connected kiln thorax pipeline No. 1, connecting No. 2 kiln thorax pipelines is connected, improvements are, it also has two gas pipelines, one end of two gas pipelines connects respectively flue gas and diffuses flashboard and two burning commutation flashboards, the other end of two gas pipelines respectively has respectively two subtubes, two subtubes of each gas pipeline are connected with deduster with combustion fan respectively, on each subtube, by-pass valve control is installed.
Above-mentioned pair of thorax heat accumulating type lime shaft kiln flue gas heat exchanging pipe, is provided with checker brick in described two gas pipeline inner chambers, is evenly equipped with the passage of up/down perforation on checker brick, and passage is arranged along the axially parallel of gas pipeline.
The beneficial effects of the utility model are:
Two gas pipelines changed into by original combustion air pipeline and flue by the utility model, each gas pipeline has respectively two subtubes to be connected with deduster with combustion fan, on each subtube, by-pass valve control is installed, combustion air and the flue gas of such two burning kiln thoraxes can be used alternatingly improved gas pipeline.In two gas pipelines, checker brick are installed, when gas pipeline is walked flue gas, the heat of flue gas is passed to checker brick, and flue gas is lowered the temperature; When gas pipeline is walked combustion air, the heat of checker brick is passed to air, and air is heated.This transformation not only can recovered flue gas waste heat, can also prevent from burning out because flue-gas temperature is too high dust-collecting bag.Meanwhile, because temperature after flue gas heat exchange is lowered, in the time selecting dust-collecting bag, just can select low temperature sack cleaner, reduce the investment of deduster.The utility model is simple in structure, transformation is easy, result of use is remarkable, can absorb better the heat in flue gas, saves the energy, has improved the economic benefit of enterprise, is also conducive to environmental protection.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of checker brick.
In figure, mark is as follows: chimney 1, flue gas diffuse flashboard 2, burning commutation flashboard 3, No. 1 kiln thorax pipeline 4 of connection, connection No. 2 kiln thorax pipelines 5, gas pipeline 6, gas pipelines 7, the subtube 8 that connects combustion fan, the subtube 9 that connects deduster, by-pass valve control 10, checker brick 11, passage 12.
Detailed description of the invention
The utility model comprises that chimney 1, flue gas diffuse flashboard 2, two burning commutation flashboards 3, connect No. 1 kiln thorax pipeline 4, connect No. 2 kiln thorax pipelines 5, gas pipeline 6, gas pipeline 7.
In figure, show, chimney 1, flue gas diffuse flashboard 2, two burning commutation flashboards 3, connect No. 1 kiln thorax pipeline 4, to connect No. 2 kiln thorax pipelines 5 identical with original pair of thorax heat accumulating type lime shaft kiln structure, flue gas diffuses flashboard 2 and is connected with two burning commutation flashboards 3 respectively, two burning commutation flashboards 3 respectively with is connected No. 1 kiln thorax pipeline 4, No. 2 kiln thorax pipelines 5 of connection and is connected.
In figure, show, improvements of the present utility model are, original combustion air pipeline and flue are changed into gas pipeline 6, gas pipeline 7, one end of gas pipeline 6 and gas pipeline 7 connects respectively flue gas and diffuses flashboard 2 and two burning commutation flashboards 3, the other end of gas pipeline 6 and gas pipeline 7 respectively has respectively two subtubes, these two subtubes are respectively the subtube 8 that connects combustion fan, the subtube 9 that connects deduster, they are connected with deduster with combustion fan respectively, and by-pass valve control 10 is installed on each subtube.The combustion air of two burning kiln thoraxes and flue gas can be used alternatingly improved gas pipeline 6 and gas pipeline 7.
