Abstract
The utility model provides a centrifugal dehydration mummification system hot -blast furnace improvement structure, it includes hot -blast furnace shell (1), hot -blast furnace inner bag (2), hot -blast furnace inner bag (2) are adorned in hot -blast furnace shell (1), intermural formation circulation canal in hot -blast furnace inner bag (2) outer wall and hot -blast furnace shell (1) is equipped with circulated air import pipe (101), its characterized in that on hot -blast furnace shell (1) conch wall: the exit that hot -blast furnace inner bag (2) are located hot -blast furnace furnace (3) one side is provided with airflow distribution plate (4). This structure makes coldly, hot -blast does not mix in furnace, has improved the pressure in the furnace, and it is stable to make in the hot -blast furnace air current flow, simultaneously, in the furnace fuel burning abundant, mix at a distance from the gas mixing of intracavity fully, the system is more high -efficient, more energy -conserving.
Description
Technical field
The utility model belongs to waste reduction and disposal equipment technical field, specifically just relates to centrifugal dehydration anhydration system hot-blast stove structure-improved, can improve the stability that hot-blast stove runs.
Background technology
Along with the fast development of national economy, the process of industrialization of China is also constantly accelerated, but because China's industrial structure belongs to extensive style production model, expensive environmental cost has been paid while causing economic development, especially atmosphere quality goes from bad to worse, haze weather not only occurs, PM2.5 is serious not up to standard, the life and health of people is made to be subject to great threat, therefore, environmental problem more and more receives popular concern, and in various environmental pollution, the pollution of of greatest concern is air, air is difficult to take precautions against owing to can be entered human body by human body respiration, it is the key factor affecting health of people.The pollutant main source mineral of current air can be right burning, how the discarded object in fossil energy combustion process and unnecessary excess energy are recycled and extensively pay close attention to by everybody.
At present, dehydrate integral system and be widely used in all kinds of mud, wet-milling, drying and other treatment industry containing wet solid particle, can effectively reduce the discharge of the pollutant to air, its range of application is also among constantly expanding.The vitals dehydrated in integral system is hot-blast stove, its Main Function produces heat by the fuel in combustion furnace, forms overheated gas, and be delivered in centrifugal dehydration anhydration system by hot-blast stove fire door, the mud that dry moisture content is larger, mud granule after formation mummification.In addition, hot-blast furnace body arranges return air inlet, the circulated air that after making to carry out heat exchange in system, temperature is lower is got back in stove and is again heated.As shown in Figure 1; the structure of traditional hot-blast stove take into account circulated air melt down in heat again; certain fuel can be saved; but the circulated air of this structure enters burner hearth inside when mixing, because of close to flame combustion district, air-flow in its region of easy disturbance; aflame flame can be made to be dispelled, elongate even to press and go out; cause that furnace pressure is chaotic, fuel combustion is insufficient or CO gas content transfinites causes system-down etc., cause system run all right to reduce, energy-saving effect is not remarkable.
Utility model content
The purpose of this utility model is exactly for the inadequate technological deficiency of existing centrifugal dehydration anhydration system hot-blast stove job stability, design a kind of centrifugal dehydration anhydration system hot-blast stove structure-improved, existing hot-blast stove structure is improved, air current flow in hot-blast stove is stablized, improve the adequacy of hearth of hot-blast stove combustion, save the energy.
Technical scheme
Above-mentioned centrifugal dehydration anhydration system hot-blast stove structure-improved, it comprises hot-blast stove shell, hot-blast stove inner bag, hot-blast stove inner bag are contained in hot-blast stove shell, circulation canal is formed between hot-blast stove inner bladder outer wall and hot-blast stove outer casing inner wall, hot-blast stove shell shell wall is provided with circulated air inlet tube, it is characterized in that: be provided with airflow-distribution board inside the exit that described hot-blast stove inner bag is positioned at hearth of hot-blast stove.
Further, described airflow-distribution board is taper, and the vertex of a cone is towards hot-blast stove furnace bottom side.
Further, described airflow-distribution board is covered with pore.
Further, described hot-blast stove furnace bottom is equipped with burner.
Beneficial effect
A kind of centrifugal dehydration anhydration system hot-blast stove structure-improved that the utility model provides, existing hot-blast stove structure is improved, this structure makes hot and cold wind not mix in burner hearth, improve the pressure in burner hearth, air current flow in hot-blast stove is stablized, and meanwhile, burner hearth fuel combustion is abundant, gas and vapor permeation in mixed cells is abundant, system more efficiently, more energy-conservation.
Accompanying drawing explanation
Accompanying drawing 1 is existing hot-blast stove structural representation.
Accompanying drawing 2 is structural representations of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in Figure 2, a kind of centrifugal dehydration anhydration system hot-blast stove structure-improved, it comprises hot-blast stove shell 1, hot-blast stove inner bag 2, hot-blast stove inner bag 2 are contained in hot-blast stove shell 1, circulation canal is formed between hot-blast stove inner bag 2 outer wall and hot-blast stove shell 1 inwall, hot-blast stove shell 1 shell wall is provided with circulated air inlet tube 101, it is characterized in that: be provided with airflow-distribution board 4 inside the exit that described hot-blast stove inner bag 2 is positioned at hearth of hot-blast stove 3.
Described airflow-distribution board 4 is taper, and the vertex of a cone is towards hot-blast stove furnace bottom side.
Described airflow-distribution board 4 is covered with pore.
Described hot-blast stove furnace bottom is equipped with burner 5.
The utility model in hearth of hot-blast stove, near exit arrange a taper with the airflow-distribution board 4 being uniformly distributed aperture, when the hot gas that burning is produced is by airflow-distribution board 4, air-flow is more stable; Change circulated air return air inlet position, the circulated air making temperature lower with form a mixed cells by the thermal current intersection after airflow-distribution board 4.This structure makes hot and cold wind not mix in burner hearth, improves the pressure in burner hearth, to make in hot-blast stove air current flow stablize, and meanwhile, burner hearth fuel combustion is abundant, and the gas and vapor permeation in mixed cells is abundant, system more efficiently, more energy-conservation.
