Description
Technical field
This utility model relates to a kind of air stove, belongs to energy-saving heating equipment technical field.
Background technology
Air stove starts extensively to apply in China in late 1970s as the air stove of thermal power machinery, and it has become electric heat source and the regeneration product of conventional vapor power heat source in many industries.By long production practices, it has been realised that only utilize hot blast could improve heat utilization efficiency and hot working effect larger as medium and carrier.Tradition electric heat source and steam thermal power often configure multiple stage circulating fan in course of conveying, are allowed to finally still indirectly form hot blast and carry out operation of drying or heat.This process there will naturally be a large amount of waste energy and causes the shortcomings such as too much, the complex technical process of auxiliary device.The effect of air stove is blast heating to the temperature required, in order to improve the returns and efficiency of blast furnace；It works by " accumulation of heat " principle.Burn in combustor coal gas, and high-temp waste gas is by checker brick and is allowed to accumulation of heat, and after checker brick fully heat, air stove just can change air-supply into, and now relevant each valve that burns cuts out, and each valve of blowing is opened, and cold wind is heated through checker brick and sends.A kind of air stove disclosed in air stove of the prior art, such as Chinese patent literature CN1963358A, cold wind enters air channel and heats, is blown at air outlet, owing to air channel is too short, therefore causes heat utilization rate the highest.
Utility model content
Therefore, the purpose of this utility model is to overcome defect of the prior art, it is provided that the air stove that a kind of heat utilization rate is higher.
To achieve these goals, a kind of air stove of the present utility model, the outer gallbladder of tubular of the stainless steel being set in described enclosure including the shell of tubular of stainless steel, coaxial line, the inner bag of the stainless steel being set on the internal axis of outer gallbladder；The lower section of described shell is provided with combustor；Chamber between described shell and described outer gallbladder is separated into two chambers, first, second chamber the most from top to bottom by the first ring-type dividing plate；Described second chamber is provided with the second air inlet, and described combustor is provided with the first air inlet, and described first, second air inlet is connected to a blower fan by first, second pipeline respectively；It is separated into top-down three, the four, the 5th chambers by second partition and the 3rd dividing plate inside described outer gallbladder；Described inner bag is installed in described 4th chamber；Described inner bag includes the first inner bag portion of superposed tubular and is positioned at the second inner bag portion of tubular of bottom, the external diameter in described first inner bag portion is more than the external diameter in described second inner bag portion, between described first inner bag portion and described 5th chamber by multiple be vertically arranged multiple walk smoke pipe connect, between described 5th chamber and described 3rd chamber pass through multiple smoke pipes of walking being vertically arranged connect；The top of described 3rd chamber is provided with chimney；The lower end in described second inner bag portion be provided through described 5th chamber and be communicated in described combustor enter fire tube.
It is respectively arranged with valve on described first, second pipeline.
Described walk smoke pipe be evenly distributed on the circumference of described inner bag around.
Use technique scheme, air stove of the present utility model, combustion air and heat exchange air is sent into air stove respectively by blower fan, after combustion air enters combustor, flame and flue gas in combustor together enter inner bag, and it is downwardly into the 5th chamber by walking smoke pipe, then through walking smoke pipe entrance the 3rd chamber, discharging through chimney；Heat exchange air enters the second chamber, then enters the 4th chamber, take away in the flow process of the 4th chamber described in walk the heat of smoke pipe after enter the first chamber, be more outwards delivered to heating equipment through the first chamber.Owing to being provided with away smoke pipe, make the downward flowing of the most upwards turning back of flue gas, add air channel length, add flue gas flowing time in pipe such that it is able to fully carry out heat exchange, and then add the thermal efficiency, improve the utilization rate of heat energy.Walking smoke pipe to be vertically arranged, the ash in flue gas is difficult to hang on tube wall simultaneously, but vertical walk smoke pipe in vertically fall, therefore walk smoke pipe and be not easily blocked；Carry out accumulation of heat by multi-chamber, and carry out heat exchange by multi-chamber, it is also possible to make heat fully be utilized, improve the thermal efficiency of air stove.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in air stove of the present utility model combustion air and heat exchange air flow to schematic diagram.
Detailed description of the invention
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As it can be seen, the present embodiment provides a kind of air stove, the inner bag 3 of the stainless steel be set in the outer gallbladder 2 of the tubular of the stainless steel described shell 1 within including the shell 1 of tubular, the coaxial line of stainless steel, being set in inside outer gallbladder 2 on axis；The lower section of described shell 1 is provided with combustor 4；Chamber between described shell 1 and described outer gallbladder 2 is separated into two chambers, first, second chamber 5,6 the most from top to bottom by the first ring-type dividing plate 100；Described second chamber 6 is provided with the second air inlet 7, and described combustor is provided with the first air inlet 8, and described first, second air inlet 7,8 is connected to a blower fan 11 by first, second pipeline 9,10 respectively；Described outer gallbladder 2 is internal is separated into top-down three, the four, the 5th chambers 12,13,14 by second partition 200 and the 3rd dividing plate 300；Described inner bag 3 is installed in described 4th chamber 13；Described inner bag 3 includes the first inner bag portion 3a of superposed tubular and is positioned at the second inner bag portion 3b of tubular of bottom, the external diameter of the described first inner bag portion 3a external diameter more than described second inner bag portion 3b, between described first inner bag portion 3a and described 5th chamber 14 by multiple be vertically arranged multiple walk smoke pipe 15 connect, connected by multiple smoke pipes 15 of walking being vertically arranged between described 5th chamber 14 and described 3rd chamber 12；The top of described 3rd chamber 12 is provided with chimney 16；The lower end of described second inner bag portion 3b be provided through described 5th chamber 14 and be communicated in described combustor 4 enter fire tube 17.
