Summary of the invention
The utility model mainly provides a kind of heat can fully recycled in flue gas, fire box temperature is significantly improved, energy-conserving and environment-protective band flue gas, air heat exchanger large stove, solve the energy consumption existed in prior art high, the thermal efficiency is low, directly cause fire box temperature not enough, and heat during fume emission is not fully recycled, not only cause energy waste, and nuisance is fully volatilized the technical problem of after stain air etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of band flue gas, the large stove of air heat exchanger, comprise furnace shell and be supported on the pot on furnace shell, furnace shell and pot enclose burner hearth jointly, on furnace shell, setting-in burner and flue collector, the upper port of burner extends in burner hearth corresponding with the bottom of pot, it is outer and be communicated with fuel gas source and air channel by blender that the lower port of burner extends to furnace shell, the upper port of flue collector is communicated with burner hearth, the lower port of described flue collector is communicated with heat exchanger, be interspersed with set of heat exchange tubes on the heat exchanger, set of heat exchange tubes serial communication is on air channel.By heat exchangers in series on flue collector, when flue gas enters flue and enters heat exchanger, namely heat exchange is carried out by heat exchanger, due to heat exchanger being interspersed with set of heat exchange tubes, heat exchanger carries out heat exchange with set of heat exchange tubes again, again because set of heat exchange tubes is that serial communication is on air channel, set of heat exchange tubes carries out heat exchange with the air in air channel again, thus the air themperature entering blender is raised, hot-air not only makes fire box temperature raise, also impel combustion gas can Thorough combustion simultaneously, fire box temperature is further enhanced, the thermal efficiency is high, save energy consumption, and the flue-gas temperature reduction owing to discharging, nuisance in flue gas is reduced, be beneficial to environmental protection.
As preferably, described heat exchanger comprises the housing of serial communication on flue collector, set of heat exchange tubes is vertically interted between two sidewalls relative on housing, the lower port of flue collector is communicated with on one end port of housing, the other end port of housing is communicated with one end of auxiliary flue, and the other end of auxiliary flue is connected with air.Heat converter structure is simple, by arranging the docking of auxiliary flue on the heat exchanger, is beneficial to the directed point discharge of flue gas.
As more preferably, described housing is cylindrical with being located in immediately below furnace shell, set of heat exchange tubes coaxial vertical interts between the end face and bottom surface of housing, air channel level is communicated with the lower port of set of heat exchange tubes, the upper port of set of heat exchange tubes is communicated with the lower port of blender by flaring transition conduit, and fuel gas source is communicated with on the outer corresponding blender bottom surface of transition conduit.When columniform heat exchanger shell is positioned at immediately below furnace shell, is easy to lay and pipeline connection, flue gas and heat exchanger can be made to carry out sufficient heat exchange, save energy consumption further.
As more preferably, several flue collectors uniform on the outer corresponding furnace shell of described blender.Multiple flue collector is set by uniform on furnace shell, namely evenly discharges flue gas timely by flue collector heat exchanger, improve the heat exchange efficiency of heat exchanger when guaranteeing that fume emission is unimpeded.
As more preferably, described housing is vertical at below furnace shell corresponding to blender periphery, set of heat exchange tubes level is interted between two sides that housing is relative, air channel vertical connection the external port of set of heat exchange tubes, the inner port level of set of heat exchange tubes is communicated with on the sidewall of blender, and fuel gas source is communicated with in the lower port of blender.Need the side that also heat exchanger shell can be vertically set on blender according to structure, thus can remaining space be made full use of, make overall structure compact and reasonable more.
As preferably, described set of heat exchange tubes comprises several thermal conductive pipes run through on the heat exchanger, and thermal conductive pipe is uniform on the heat exchanger that air channel is corresponding.The set of heat exchange tubes be made up of several thermal conductive pipes, structure is simple, when each thermal conductive pipe is uniform on the heat exchanger, guarantees that heat exchange is evenly abundant.
As preferably, be arranged with the loop bracket of truncated cone-shaped outside burner corresponding in described burner hearth, the outside wall surface of loop bracket is supported on furnace shell internal face by fire clay, and on the internal face of loop bracket, interworking is provided with reflection basin.Carrying out supporting reflex basin by arranging loop bracket in burner hearth, collecting heat by reflection basin and to the bottom of a pan reflection, reducing energy loss further, improving the thermal efficiency.
As preferably, on the edge, bottom surface of described furnace shell, vertical support several stove pin.Stove pin can guarantee that furnace shell obtains gentle support.
Therefore, the large stove of band flue gas of the present utility model, air heat exchanger has following advantage: fire box temperature can bring up to about 200 DEG C, the air themperature entering burner hearth after flue gas heat exchange can reach 100 DEG C, and flue-gas temperature declines about 50% simultaneously, energy-conservation up to 45%.
