Technical field
The utility model relates to technical field of waste heat recycling, particularly a kind of waste heat of boiler tail gas recycle device.
Background technology
At present, containing amount of heat in the tail gas that boiler emission goes out, temperature is higher, if tail gas is directly discharged in air, not only a large amount of heat energy can be wasted, and meeting atmosphere pollution, cause environment temperature to raise, therefore, need to recycle the waste heat of tail gas.Current tail gas waste heat recovery use apparatus, structure is more complicated, and manufacturing cost is high, and recovery utilization rate is not high yet.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide one effectively can reclaim the simple and lower-cost waste heat of boiler tail gas recycle device of using waste heat from tail gas, structure.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of waste heat of boiler tail gas recycle device, comprise boiler, first blower fan, second blower fan, first pipeline, second pipe, tail gas escape pipe and tail gas funnel, first set pipe is set with outside described tail gas funnel, the second sleeve pipe is set with outside described tail gas escape pipe, described tail gas escape pipe and described tail gas funnel are connected, described first sleeve pipe and the second sleeve pipe are connected, described second sleeve pipe is provided with air outlet slit, the air outlet slit of this second sleeve pipe connects the first blower fan, this first blower fan is connected with the second blower fan by the first pipeline, described second blower fan is connected with described boiler by second pipe again, described boiler is connected with described tail gas escape pipe again, the tail gas funnel connected with tail gas escape pipe has an offgas outlet.
Further, described first sleeve pipe and the second sleeve pipe all adopt stainless steel to make.
Further, the wall thickness of described first sleeve pipe and the second sleeve pipe is 2mm.
Further, described first sleeve pipe and the second sleeve pipe are all coated with aluminium skin outward, and are equipped with rock wool layer between the first sleeve pipe and aluminium skin and between the second sleeve pipe and aluminium skin.
Further, described first sleeve pipe is enclosuring structure away from one end of the offgas outlet of tail gas funnel.
Further, the external port of described second sleeve pipe is open-ended structure.
The beneficial effects of the utility model are: be set with first set pipe outside the tail gas funnel in the utility model, the second sleeve pipe is set with outside tail gas escape pipe, the tail gas that boiler is discharged is discharged via tail gas escape pipe and tail gas funnel successively, when tail gas is through tail gas escape pipe and tail gas funnel, because air enters boiler via the first sleeve pipe be enclosed within tail gas funnel and the second sleeve pipe be enclosed within tail gas escape pipe, thus the tail gas in tail gas escape pipe and tail gas funnel produces heat exchange with the air entered, thus the air themperature entering boiler is raised, contribute to improving fuel gas temperature in boiler, improve the production efficiency of boiler, the waste heat of tail gas is also recycled utilization, both the energy had been saved, be conducive to environmental protection again.And total of the present utility model is comparatively simple, and cost of manufacture and production cost are also lower, higher to the recovery utilization rate of using waste heat from tail gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1, a kind of waste heat of boiler tail gas recycle device, comprise boiler 1, first blower fan 2, second blower fan 3, first pipeline 4, second pipe 5, tail gas escape pipe 6 and tail gas funnel 7, first set pipe 8 is set with outside described tail gas funnel 7, the second sleeve pipe 9 is set with outside described tail gas escape pipe 6, described tail gas escape pipe 6 is connected with described tail gas funnel 7, described first sleeve pipe 8 and the second sleeve pipe 9 are connected, described second sleeve pipe 9 is provided with air outlet slit 91, the air outlet slit 91 of this second sleeve pipe 9 connects the first blower fan 2, this first blower fan 2 is connected with the second blower fan 3 by the first pipeline 4, described second blower fan 3 is connected with described boiler 1 by second pipe 5 again, described boiler 1 is connected with described tail gas escape pipe 6 again, the tail gas funnel 7 connected with tail gas escape pipe 6 has an offgas outlet 71.
Furtherly, described first sleeve pipe 8 and the second sleeve pipe 9 all adopt stainless steel to make.
Furtherly, the wall thickness of described first sleeve pipe 8 and the second sleeve pipe 9 is 2mm.
Furtherly, be all coated with aluminium skin outside described first sleeve pipe 8 and the second sleeve pipe 9, and be equipped with rock wool layer between the first sleeve pipe 8 and aluminium skin and between the second sleeve pipe 9 and aluminium skin.The structure that aluminium skin adds rock wool layer has good heat insulation effect, can reduce the loss of heat.
Furtherly, described first sleeve pipe 8 is enclosuring structure away from one end of the offgas outlet 71 of tail gas funnel 7.
Furtherly, the external port of described second sleeve pipe 9 is open-ended structure.
During work, under the effect of the first blower fan 2 and the second blower fan 3, air is successively by the second sleeve pipe 9 of suit on the first sheathed sleeve pipe 8 on tail gas funnel 7 and tail gas escape pipe 6, then enter the first blower fan 2 from the air outlet slit 91 of the second sleeve pipe 9, then after the first pipeline 4, second blower fan 3 and second pipe 5, enter boiler 1 successively.Concrete, air enters from the space between the outer wall and the inwall of the second sleeve pipe 9 of the space between the outer wall and the inwall of the first sleeve pipe 8 of tail gas funnel 7 and tail gas escape pipe 6.While air enters, tail gas discharged by boiler 1.After tail gas is got rid of from boiler 1, successively through tail gas escape pipe 6 and tail gas funnel 7, discharge via the offgas outlet 71 on tail gas funnel 7.When tail gas is through tail gas escape pipe 6 and tail gas funnel 7, because air enters boiler 1 via the first sleeve pipe 8 be enclosed within tail gas funnel 7 and the second sleeve pipe 9 be enclosed within tail gas escape pipe 6, thus the tail gas containing amount of heat in tail gas escape pipe 6 and tail gas funnel 7 produces heat exchange with the air newly entered, thus improve the temperature of the air entering boiler 1, contribute to improving fuel gas temperature in boiler, thus improving the production efficiency of boiler 1, the waste heat of tail gas is also recycled utilization.
