Abstract
The utility model provides a jacket hot flue gas distribution device of an external heated rotary furnace. A rotary furnace outer jacket is divided into a three-section structure which comprises an inlet jacket, a straight-section jacket and an outlet jacket, a flue gas divider shaped like a Chinese character 'ren' is arranged in the center of a hot flue gas inlet in the inlet jacket, the lower portion of the flue gas divider is closed, and due to the action of the divider, hot flue gas flows towards two sides in the circumferential direction after entering the jacket. A circle of annular plate is arranged in the inlet jacket and on the outer side of a rotary furnace barrel, and a plurality of circular holes are evenly formed in the annular plate in the circumferential direction. Due to the arrangement of the flue gas divider and the circular plate with the holes evenly formed in the circumferential direction, the hot flue gas enters the inlet jacket, disperses in the circumferential direction, then axially moves and finally evenly flows out of the outlet jacket in the circumferential direction, it is guaranteed that the full-section hot flue gas in the jacket is distributed evenly and materials are heated evenly, and therefore heating efficiency and product quality are improved.
Description
Technical field
The utility model relates to the jacket structured of a kind of external heat type rotary furnace.
Background technology
In the industries such as chemical industry, metallurgy, building materials, Roarykiln is widely used in dry, the reaction of material, the operation such as cooling.In the dry and course of reaction of rotary furnace, generally need to provide heat by heat-carrying agent.According to heat-carrying agent, whether can directly contact with material, be divided into two kinds of rotary furnaces of internal heat type and external-heat.External heat type rotary furnace is normally at rotary furnace cylindrical shell arranged outside chuck, and in chuck, carries high warm flue gas to provide heat to reaction in furnace or dry run.Conventional external heat type rotary furnace chuck only arranges gas approach and exhanst gas outlet at present, hot flue gas is from import enters chuck, just directly to outlet, flow vertically, only a small amount of flue gas along the circumferential direction spreads, therefore hot flue gas is at body of heater circumferencial direction skewness, thereby cause in stove the material inequality of being heated, affect the efficiency of heating surface and product quality.
Summary of the invention
The shortcoming existing for existing external heat type rotary furnace, the utility model provides a kind of chuck of external heat type rotary furnace hot smoke distribution device, has guaranteed that hot flue gas is uniformly distributed in chuck, thus material is heated evenly and has improved the efficiency of heating surface and product quality.
The technical solution of the utility model is: a kind of hot smoke distribution device of chuck of external heat type rotary furnace, it is characterized in that rotary furnace external jacket is divided into three-stage structure: import chuck, straight section chuck, outlet chuck, the chuck at hot gas approach place is import chuck, the chuck of hot smoke outlet is outlet chuck, and all the other are straight section chuck.The center at hot gas approach place on import chuck, arranges the chevron shaped flue gas shunting device that a bottom is sealed, and due to the effect of current divider, hot flue gas flows along circumferential both sides after entering chuck.On current divider, a circular hole is respectively opened on both sides, to guarantee current divider chamber inside and outside air pressure balance.
In import chuck, rotary furnace cylindrical shell arranged outside one ring plate, on ring flat-plate, along the circumferential direction evenly open a plurality of circular holes, due to ring flat-plate being set, so import chuck has been divided into two chambeies: exocoel and inner chamber, and ring flat-plate docks with straight section chuck, so import chuck inner chamber and straight section chuck chamber UNICOM.When hot flue gas enters after import chuck, due to the effect of ring flat-plate, hot flue gas cannot directly flow to outlet vertically, can only along the circumferential direction by the perforate on ring flat-plate, enter equably import chuck inner chamber, then by straight section chuck, to outlet chuck, flows.
Outlet chuck is arranged on the other end of straight section chuck, in outlet chuck, rotary furnace cylindrical shell outside arranges the ring flat-plate that a circle is evenly opened a plurality of circular holes equally, therefore exporting chuck has also been divided into two chambeies: exocoel and inner chamber, and outlet chuck inner chamber and straight section chuck chamber UNICOM.When hot flue gas flows along straight section chuck to outlet chuck, effect due to ring flat-plate, hot flue gas cannot directly flow along beeline thermotropism exhanst gas outlet, can only flow to vertically after the inner chamber of outlet chuck, by the perforate of ring flat-plate, along the circumferential direction enter equably again the exocoel of outlet chuck, and then flow out from hot exhanst gas outlet.
Effect of the present utility model: because hot gas approach is provided with flue gas shunting device, import chuck and outlet chuck are provided with along the circumferential direction the evenly Circular Plate of perforate, after making hot flue gas enter import chuck, first along the circumferential direction spread, move vertically again, finally along the circumferential direction from exporting chuck, flow out equably again, thereby guaranteed that the hot smoke distribution of the interior full section of chuck is even, material is heated evenly and has improved the efficiency of heating surface and product quality.
Accompanying drawing explanation
Fig. 1 is the jacket structured schematic diagram of import.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is import chuck, straight section chuck and exports jacket structured schematic diagram.
The specific embodiment
As shown in Figure 1 and Figure 2, the center at hot gas approach 1 place on import chuck 3, arranges the chevron shaped flue gas shunting device 2 that a bottom is sealed, and due to the effect of current divider 2, hot flue gas flows along circumferential both sides after entering chuck.On the straight flange of current divider 2, open a circular hole, to guarantee current divider chamber inside and outside air pressure balance.
As shown in Figure 1, in import chuck 3, rotary furnace cylindrical shell 5 arranged outside one ring plates 4, on ring flat-plate 4, along the circumferential direction evenly open a plurality of circular holes, due to ring flat-plate 4 being set, therefore import chuck 3 has been divided into two chambeies: exocoel and inner chamber, and ring flat-plate 4 docks with straight section chuck 6, so import chuck 3 inner chambers and straight section chuck 6 chamber UNICOMs.When hot flue gas enters after import chuck 3, due to the effect of ring flat-plate 4, hot flue gas cannot directly flow to outlet vertically, can only along the circumferential direction by the perforate on ring flat-plate 4, enter equably import chuck 3 inner chambers, then by straight section chuck 6, to outlet, flows.
As shown in Figure 3, outlet chuck 7 is arranged on the other end of straight section chuck 6, in outlet chuck 7, rotary furnace cylindrical shell 5 outsides arrange the ring flat-plate 4 that a circle is evenly opened a plurality of circular holes equally, therefore exporting chuck 7 has also been divided into two chambeies: exocoel and inner chamber, and outlet chuck 7 inner chambers and straight section chuck 6 chamber UNICOMs.When hot flue gas flows along straight section chuck 6 to outlet chuck 7, effect due to ring flat-plate 4, hot flue gas cannot directly flow along beeline thermotropism exhanst gas outlet 8, can only flow to vertically after the inner chamber of outlet chuck 7, by the perforate of ring flat-plate 4, along the circumferential direction enter equably again the exocoel of outlet chuck 7, and then flow out from hot exhanst gas outlet 8.
