Description
Technical Field
The utility model belongs to the technical field of the material is dried, especially relate to the hot-blast furnace of cyclic utilization flue gas with gas or fuel as the fuel for the stoving.
Background
In a drying process system, a traditional gas or oil hot blast stove heats natural air by burning fuel through a burner to obtain hot flue gas, usually mixes certain natural wind with the hot flue gas, outputs the hot blast stove and inputs the hot blast stove into drying equipment through a pipeline; in order to improve the energy utilization rate, part of the flue gas discharged by the drying process system can return to the drying system for recycling; in a traditional drying process system, the recirculated flue gas and the flue gas output by the hot blast stove are input into a drying device to dry materials in a parallel connection mode, namely, the two flue gases are equivalent to two independent flue gases.
As above, the traditional drying process with parallel input has complex process flow and low system thermal efficiency.
Disclosure of Invention
The utility model discloses a hot-blast furnace of novel structure is taken promptly to the purpose, and circulation flue gas and hot-blast furnace series combination simplify process flow, improve the system thermal efficiency.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a novel hot-blast furnace, includes combustor, boiler barrel body, inner skleeve, wind guide vane, hot air exitus, circulation flue gas entry, characterized by, the central point of the tip of boiler barrel body one end puts and is provided with combustor mounting flange, the combustor install in mounting flange is last, the inner skleeve is located the boiler barrel body, and concentric with the boiler barrel body, by the different more than two sections of diameter, according to hot-blast flow direction by little diameter setting to big, every section all with boiler barrel body fixed connection, one section length of embedding each other between every section with wind guide vane fixed connection forms the mixed wind passageway, be provided with the through-hole on the inner skleeve, be provided with circulation flue gas entry on the outer wall that the boiler barrel body is close to combustor one end, hot air exitus sets up on the other end boiler barrel body that combustor mounting.
Furthermore, in order to accelerate the flow of the circulating flue gas and facilitate the sufficient mixing of the circulating flue gas and the hot flue gas generated by the hot blast stove in a hearth of the hot blast stove, two ends of the air guide blade are respectively and fixedly connected to the mutually embedded positions of the two adjacent sections of inner sleeves and are obliquely arranged with the inner sleeves.
Further, the through holes are uniformly distributed on the inner sleeve wall.
The utility model has the advantages that: through the inlet setting of circulation flue gas and the setting of inner skleeve merogenesis embedding setting, wind guide vane's slope setting and the setting of through-hole on the inner skleeve, the heat energy that can effective reuse circulation flue gas realizes fuel economy to tail gas emission has been reduced, energy-concerving and environment-protective effect has been reached.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can smoothly implement the present invention.
A novel hot blast stove comprises a burner 01, a stove cylinder 02, an inner sleeve 03, air guide blades 04, a hot blast outlet 09 and a circulating flue gas inlet 05, it is characterized in that a burner mounting flange 06 is arranged at the central position of the end part of one end of the furnace cylinder body, the burner 01 is arranged on the mounting flange 06, the inner sleeve 03 is positioned in the furnace cylinder body 02, concentric with the furnace cylinder body 02, composed of more than two sections with different diameters, arranged according to the diameter from small to large in the hot air flowing direction, each section is fixedly connected with the furnace cylinder body 02, a section of length is embedded between each section and is fixedly connected with the air guide blade 04 to form an air mixing channel 07, a through hole is arranged on the inner sleeve 03, a circulating flue gas inlet 05 is arranged on the outer wall of one end of the furnace cylinder body 02 close to the burner, the hot air outlet 09 is arranged on the furnace cylinder body 02 at the other end opposite to the mounting flange of the burner. Two ends of the air guide blades 04 are respectively fixedly connected to the mutually embedded positions of the two adjacent inner sleeves and are obliquely arranged with the inner sleeves 03, and different modes such as welding, riveting and the like can be selected according to the connection mode of the air guide blades 04 and the inner sleeves 03.
The through holes are uniformly distributed on the wall of the inner sleeve 03, and different or same shapes and numbers can be selected.
Combustion-supporting air with certain mixed fuel gas or fuel oil is combusted by the combustor 01 and is sprayed forwards, and flame is distributed in the inner sleeve 03 along the axial direction; all circulating smoke of the drying process system enters a circulating smoke channel 08 formed between the furnace cylinder body 02 and the inner sleeve 03 through a circulating smoke inlet 05, the cross section of the circulating smoke channel 08 is gradually reduced from the furnace head to the furnace tail, and the circulating smoke enters the inner sleeve 03 from the circulating smoke channel 08 through an air mixing channel 07 to be mixed with the combusted high-temperature smoke; the mixed flue gas is input into the drying equipment through a hot air outlet 09 and a pipeline.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
