Abstract
The utility model relates to a high temperature hot air furnace which is used for heating cold air. The utility model comprises a furnace body and a furnace seat. An air interlayer, an air guiding hole, and an air outlet are arranged at the outer circumference of the furnace body; a bundle of heat conducting pipes arranged in a transverse recuperative way; two ports of each heat conducting pipe are communicated with the air interlayer; a group of air blocking rings with openings are arranged in the air interlayer; the direction of the openings of the air blocking rings is same with the direction of the ports of the heat conducting pipes, and the openings of the air blocking rings are staggered; both sides of an air inlet of each heat conducting pipe are provided with flow blocking plates. The utility model has the advantages of good heat conduction performance and fast temperature rise, and can improve the using efficiency of equipment.
Description
The utility model relates to the employed a kind of high temperature hot-blast furnace of a kind of heating cold wind.
The traditional type hot-blast stove comprises body of heater and stove seat substantially, is surrounded by air jacket around the described body of heater, is welded with the heat exchange gusset in the chuck, and described air jacket is provided with air-vent and air outlet.The shortcoming of above-mentioned hot-blast stove is: the cold wind that is input in the chuck can not get abundant heating, and heat exchange efficiency is low, waste fuel.
The purpose of this utility model provides a kind of high temperature hot-blast furnace that a kind of heat exchange effect is good, increase cold air flow process, fuel saving.
The utility model is achieved in that a kind of high temperature hot-blast furnace, comprise body of heater and stove seat, there is air blanketing the outside of described body of heater, and be provided with air-vent and air outlet, the below of body of heater is the combustion chamber, it is characterized in that: be provided with the heat pipe that a branch of horizontal dividing wall type is arranged in the burner hearth of described body of heater, the two-port of this heat pipe communicates with air blanketing, be provided with one group of wind loop that has opening in the described air blanketing, the opening direction of this wind loop is consistent with the port direction of heat pipe, and be staggered, the air intake port both sides of described heat pipe are provided with the flow-stopping plate that links to each other with wind loop.Described heat pipe is the arch that raises up.The combustion chamber of described body of heater below is provided with a fuel-feed pipe.
The utility model mainly is to be provided with the heat pipe that a branch of horizontal dividing wall type is arranged in the burner hearth at body of heater middle part, the port of this heat pipe communicates with the air blanketing of body of heater periphery wall, be provided with one group of wind loop that has opening in the described air blanketing, the opening direction of this wind loop is consistent with the heat pipe direction, and be staggered up and down, therefrom heat pipe is divided into multilayer, the both sides of the inlet air port of every layer of heat pipe are provided with the flow-stopping plate of setting, after cold wind enters air blanketing from the air-vent of body of heater bottom, make cold wind direct puncture burner hearth in the heat pipe enter the air blanketing on opposite by wind loop and flow-stopping plate guiding, enter the upper strata from the opening of wind loop, heat pipe from the upper strata passes again, make cold wind S-shaped streamline heating in burner hearth, discharge by the air outlet on the air blanketing at last.Heat pipe in the described burner hearth is arch, can avoid in use heat pipe to stay like this and is out of shape.
The utility model compared with prior art has following advantage: heat-conductive characteristic is good, has increased heat exchange area, makes the time of staying of cold wind in hot-blast stove long, can fully carry out heat exchange.Because what the utility model adopted is the transverse tube dividing wall type, and heat pipe all is in the encirclement of flame, therefore, temperature rises fast, can improve the service efficiency and the fuel saving of equipment simultaneously.
Drawing is described as follows:
Fig. 1 is the utility model sectional structure schematic diagram.
Fig. 2 is that shell sectional structure schematic diagram is looked on Fig. 1 left side.
Fig. 3 is Figure 1A-A sectional structure schematic diagram.
Below in conjunction with accompanying drawing the utility model is done further narration:
Referring to Fig. 1, as can be seen from Figure, the utility model comprises stove seat 1 and body of heater 13, and the below of body of heater 13 is combustion chamber 5 and is provided with into coal stove door 4 and a feed pipe 3 that wall is with refractory material 2 around this combustion chamber 5.The top of described body of heater is the truncated cone-shaped contraction section, in the body of heater, the periphery wall on top is air blanketing 9, described air blanketing 9 is by the shell 6 of body of heater and the fusion of burner hearth inner bag 7 upper and lower ends and form, and is provided with air outlet 14 and air-vent 10 respectively in the upper and lower part of shell 6.Be provided with the heat pipe 8 that a branch of horizontal dividing wall type is arranged in the burner hearth 12 of described body of heater, the two-port of this heat pipe is passed burner hearth inner bag 7 and is communicated with air blanketing 9, be provided with one group of wind loop 11 that has opening in the described air blanketing 9, thereby the cold air that enters from air-vent 10 can not directly be discharged from air outlet 14 along air blanketing 9.Referring to Fig. 2, as can be seen from Figure 2, described wind loop 11 is placed in the air blanketing 9, and the opening 17 of every layer wind loop is consistent with the mouth of pipe direction of heat pipe, and the both sides of the air inlet of described heat pipe are respectively equipped with flow-stopping plate 15.After cold wind flows out from heat pipe 16, because the effect of wind loop 11 and flow-stopping plate 15, cold wind can only enter the upper strata air blanketing from the opening 17 of wind loop 11, heat pipe 18 by the upper strata passes the air blanketing that burner hearth enters the opposite, after heated cold wind enters the contraction section on body stove top, just in air blanketing, make curvilinear style and upwards flow, discharge by air outlet at last.Fig. 3 is Figure 1A-A sectional structure schematic diagram.As can be seen from Figure, described flow-stopping plate 15 is erected in the air blanketing 9, and surround the air intake port of heat pipe, the described feed pipe that communicates with the combustion chamber 3 is oriented in a tangential direction, it can and easily burn particle and inject or be blown into the combustion chamber from feed pipe 3 with oil pump or blower fan and produce rotation some waste oil, makes burning more abundant.
