Description
Technical field
The utility model is related to boiler processing technique field, especially a kind of spiral high-efficiency hot-blast stove.
Background technology
Hot-blast stove turns into the product of electric heat source and conventional vapor power heat source, profit as thermal power machinery in many industries
With hot blast heat utilization efficiency and hot working effect could be larger improved as medium and carrier.At present, traditional hot-blast stove is in conveying
Because air channel is straight-through during natural wind, wind speed flow velocity is fast, short in residing time in furnace, makes air heating effect difference, it is necessary to match somebody with somebody
Many circulating fans are put, natural wind is largely flowed into the multiple circulating-heating of progress, heating process wastes more equipment, manufactures work
Skill is complicated, and production cost is high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, reduction production cost, slows down air
Flow velocity, the good spiral high-efficiency hot-blast stove of air heating effect.
To solve the above problems, a kind of spiral high-efficiency hot-blast stove described in the utility model, including body of heater, flue and anti-
Canopy, it is characterised in that：Be provided with heat-insulation layer on the outside of the body of heater, the heat-insulation layer bottom is provided with hot air discharging duct, and with it is described
Spiral interlayer is provided between body of heater；The upper of furnace body connects the flue by flange, and opened upper end is provided with the outside of the flue
Spiral of air layer, its over top connects the rain cover；The spiral interlayer is connected with spiral of air layer.
The spiral angle angle of the spiral interlayer is set to 40 ° -45 °.
The spiral angle angle of the spiral of air layer is set to 22 ° -30 °.
The utility model has advantages below compared with prior art：
（1）The utility model makes it due to being respectively equipped with spiral interlayer and spiral of air layer outside original body of heater and flue
It is simple in construction, reduce production cost.
（2）The utility model enters natural wind along 22 ° of -30 ° of progress screws of spiral angle due to spiral of air layer, subtracts
Slow air velocity, meanwhile, spiral angle makes air stop in body of heater for 40 ° -45 ° of spiral interlayer, flowing is uniform, heat-insulation layer
Play heat insulation effect, it is ensured that higher heating effect.
Brief description of the drawings
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structure schematic cross-sectional view of the present utility model.
In figure：1. body of heater, 2. heat-insulation layers, 3. hot air discharging ducts, 4. spiral interlayers, 5. flues, 6. spiral of air layer, 7.
Rain cover.
Embodiment
As shown in figure 1, a kind of spiral high-efficiency hot-blast stove, including body of heater 1, flue 5 and rain cover 7, the outside of body of heater 1 is provided with
Heat-insulation layer 2, the bottom of heat-insulation layer 2 be provided with hot air discharging duct 3, and between body of heater 1 provided with spiral angle angle be set to 40 °~
45 ° of spiral interlayer 4；The top of body of heater 1 connects flue 5 by flange, and the outside of flue 5 is provided with the spiral angle angle of opened upper end
Degree is set to 22 °~30 ° of spiral of air layer 6, its over top connecting rain-proof cover 7；Spiral interlayer 4 is connected with spiral of air layer 6.
During work, body of heater 1 is connected with flue 5 by flange, make in connection procedure spiral of air layer 6 spiral angle with
The spiral angle of spiral interlayer 4 is corresponding；Connect coal in backward body of heater 1 to burn, while air enters spiral of air layer 6, subtract
Slow speed air flow, when the flue gas in body of heater 1 enters flue 5, is preheated, flue gas passes through to the air of spiral of air layer 6
Flue 5 is discharged, and rain cover 7 prevents that rainy day rainwater from entering；Air enters spiral interlayer 4 after preheating, in 40 °~45 ° of spiral
In angle, air Uniform Flow, furnace body outer wall is heated to air, makes air heats good, heat-insulation layer 2 prevents heat flowing water,
It ensure that higher heating effect, hot-air are discharged after flowing to the bottom of spiral interlayer 4 by hot air discharging duct 3, into hot profit
Use equipment.
