Description
One, technical field: the utility model relates to a kind of hot-blast stove that hot blast is provided.
Two, background technology: at present, used hot-blast stove ubiquity heat exchange efficiency is not high, the fuel of a kind of form of same burning, the quantity combusted of fuel is also identical, but the efficient of heat exchange differs greatly, and this mainly is that body of heater inner structure difference causes, and how cold air stays for some time in body of heater more, and can take away the interior heat of stove very soon, be the crux that improves the hot-blast stove thermal efficiency.
Three, summary of the invention:
1, goal of the invention: the utility model provides a kind of indirect heat exchange high temperature high-efficient hot air furnace, and its purpose is to solve the problem that aspects such as the existing hot-blast stove ubiquity thermal efficiency is not high, heat exchange effect is bad exist.
2, technical scheme: the utility model is achieved through the following technical solutions:
A kind of indirect heat exchange high temperature high-efficient hot air furnace, it mainly is made up of the heat exchange body on top and the combustion chamber of lower part, it is characterized in that: be provided with a circle cavity at the heat exchange body periphery and the air intake vent place of communicating on top, be provided with heat exchanger tube in the cavity, be provided with the plug-in unit of helical structure in the heat exchanger tube; Below heat exchanger tube, be connected with wind assembling set, be provided with the jet plate of band porous in the wind assembling set.
Heat exchanger tube is 1～4 row in cavity.
The air inlet place of outer furnace wall and internal protecting wall form eccentric structure.
Heat exchange body top is provided with smoke exhaust pipe, and smoke exhaust pipe communicates with heat exchanger tube chamber outward, is provided with outlet flue in plug-in unit heat exchanger tube lower end.
Outside the combustion chamber of lower part, be provided with secondary air chamber, secondary air chamber is by being connected with the combustion chamber air pipeline that enters in the combustion chamber that is oriented in a tangential direction obliquely.
3, advantage and effect: 1. jet flow, insert, radiation, heat convection technological synthesis are used.
2. quick heating can reach more than 300 ℃ in 20 minutes, and outlet hot blast temperature height, cost are low, just can reach more than 400 ℃ without special material.
3. the adjustable rotation combustion air of Du Te secondary, fuel combustion is abundant.
4. partial fume refluxes, and improves UTILIZATION OF VESIDUAL HEAT IN, reduces temperature in the stove.
5. thermal efficiency height can reach 70%～80%.
6. various ways combustion chamber.
7. adopt eccentric all bellows, the wind that enters is evenly flowed, thermally equivalent improves temperature.
Four, description of drawings: accompanying drawing 1 is the main internal structure schematic diagram of the utility model;
Accompanying drawing 3 is the utility model heat exchanger tube arrangement architecture schematic diagram;
Five, the specific embodiment: the utility model specific embodiments is as follows:
As shown in Figure 1, the utility model comprises that mainly two parts constitute up and down.Top is divided into the heat exchange body, and the bottom is divided into the combustion chamber.Be provided with air intake vent 1 on the outer furnace wall 13 of top heat exchange body, it communicates with cavity 11 in the outer furnace wall 13, and air upwards enters into cavity 11 from the air intake vent 1 of bottom, also is outer furnace wall 13 coolings when air is carried out preheating.Be provided with a circle heat exchanger tube 4 around internal protecting wall 14 in the cavity 11, the air intake of heat exchanger tube 4 is last, be provided with into the plug-in unit 12 of helical structure in the heat exchanger tube 4, gas curl rotation from up to down downwards, the time that makes gas increase stop in the body of heater reaches the contact area with body of heater, like this, to the further heat exchange of the air of preheating, enter the wind assembling set 6 of bottom then.The jet plate 7 that porous is arranged in the wind assembling set 6, air are sprayed to the hyperthermia radiation tube with high speed by the porous on the jet plate 7 in the wind assembling set 6 again.The hyperthermia radiation tube is at the relative position of jet plate 7, and generally this position temperature is higher, and the phenomenon of leaking often takes place to burn.The utility model requires low to the inner core material because gas at this behind high speed jet, in time take away heat, reduce the temperature of inner core, after the jet flow, hot blast enters top again, forms high-temperature hot air through radiation, heat convection, is discharged by air outlet 2.
Heat exchange body top is provided with a circle smoke exhaust pipe 3, and smoke exhaust pipe 3 communicates (chamber 15 does not communicate with cavity 11) with heat exchanger tube 4 chamber 15 outward, is provided with outlet flue 5 in plug-in unit heat exchanger tube 4 lower ends.Outside the combustion chamber of lower part, be provided with secondary air chamber 8, secondary air chamber 8 is by being connected with the combustion chamber air pipeline 16 that enters in the combustion chamber that is oriented in a tangential direction obliquely.Like this, the fuel in the combustion chamber can fully burn.
The combustion chamber of self-supporting energy hot-blast stove can be made into the pattern that adapts to different fuel, can be coal-fired (hand burning, machine burning or add under watch the formula coal burning machine), fuel oil, combustion gas.Flue gas enters the tubulation Heat Room by the smoke exhaust pipe of passing through on the inner core, is discharged by outlet flue again.
As shown in Figure 2, outer furnace wall 13 air inlet places and internal protecting wall 14 form eccentric structure.Can guarantee the wind thermally equivalent that enters like this.
The utility model can be provided with 1～4 row's heat exchanger tube 4, and accompanying drawing 3 is depicted as two row's heat exchanger tubes 4, what is set mainly according to the thickness of the internal diameter and the heat exchanger tube 4 of body of heater.
Fig. 4 is the concrete structure that is inserted into heat exchanger tube 4 plug-in parts 12, and plug-in unit shown in the figure 12 is a helical structure, and gas turns to current downflow by plug-in unit 12 in heat exchanger tube 4 inward turnings.One end of plug-in unit 12 has backing pin 16, by backing pin 16 plug-in unit 12 is ridden over the air inlet place of heat exchanger tube 4, and the other end is fixed.
