Description
Technical field
The utility model relates to a kind of boiler afterheat recycle device.
Background technology
At present, no matter all there are thermal efficiency problem on the low side in coal-burning boiler, gas fired-boiler or oil burning boiler.One of them major reason is that a large amount of heat energy slattern in atmosphere with fume emission.Along with becoming increasingly conspicuous of the nervous problem of global energy, this problem more and more receives publicity and payes attention to.This energy waste directly causes heat cost high on the one hand, and on the other hand, high-temperature flue gas carries a large amount of heats and dust emission causes environmental pollution and atmosphere temperature to raise in atmosphere.
Utility model content technical problem to be solved in the utility model is, a kind of boiler afterheat recovering device is provided, and by the boiler combustion discharged flue gas is recycled, reduces fuel cost, improves heat utilization ratio, alleviates environmental pollution.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme.
A kind of boiler afterheat recovering device comprises the wall body that has heat-insulation layer, it is characterized in that: wall body one side is provided with into mouth, and opposite side is provided with outlet flue; Also offer into air scoop on the wall body respectively and go out air scoop; The inwall of diaphragm plate, vertical clapboard and wall body is divided into mutually independently three spaces with the wall body inner chamber, one is and goes out the hot-air channel that air scoop is communicated with, it is two for being communicated with the logical heat-exchanging chamber of mouth and outlet flue respectively, its three for and advance the air chamber that air scoop is communicated with; Adopt heat pipe for some and be arranged in the heat-exchanging chamber, the air inlet port of adopting heat pipe is insinuated in the air chamber, and the port of giving vent to anger of adopting heat pipe is insinuated in the hot-air channel.
Entering the air scoop outer end, air inflow is being installed regulates blinds and air cleaner.
Near advancing the adopting on the heat pipe of mouth place, be fixed with protective layer.
Also comprise the guide plate that is fixed on the wall body inwall, guide plate and vertical clapboard trend are 30-50 degree angle.
Good effect of the present utility model is: (1), utilize boiler combustion discharged flue gas heat that air is heated, get back to the indoor recycling of boiler combustion with hot-air is defeated again, can fuel savings cost about 70%.(2), the boiler combustion flue gas is mobile through turning back in this device, the not only heat utilization that is absorbed, the discharging flue-gas temperature reduces (being reduced to below 100 ℃ by original about 330 ℃), and dust wherein falls after rise and is collected removing, reduced discharging dust in flue gas density, environmental-protecting performance is very outstanding.(3), belong to atmospheric unit, security performance is good.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Shown in Fig. 1-4, the utility model comprises the wall body 1 that has heat-insulation layer, and wall body 1 one sides are provided with into mouth 5, and opposite side is provided with outlet flue 11.Also offer into air scoop 9 on the wall body 1 respectively and go out air scoop 14.Wall body 1 lower end offers clean-out door 16.In wall body 1 lower end supporting leg 15 is installed.
The inwall of diaphragm plate 6, vertical clapboard 2 and wall body 1 is divided into mutually independently three spaces with wall body 1 inner chamber, one is and goes out the hot-air channel 7 that air scoop 14 is communicated with, it is two for being communicated with the logical heat-exchanging chamber 12 of mouth 5 and outlet flue 11 respectively, its three for and advance the air chamber 8 that air scoop 9 is communicated with.Adopt heat pipe 13 for some and be arranged in the heat-exchanging chamber 12, the air inlet port of adopting heat pipe 13 is insinuated in the air chamber 8, and the port of giving vent to anger of adopting heat pipe 13 is insinuated in the hot-air channel 7.
Entering air scoop 9 outer ends, air inflow is being installed regulates blinds and air cleaner 10.Near advancing the adopting on the heat pipe 13 of mouth 5 places, be fixed with protective layer 4, avoid the too high flue gas of temperature to adopting the erosion of heat pipe 13.Guide plate 3 is fixed on the inwall of wall body 1, is 30-50 degree angle with vertical clapboard 2 trends.The effect of guide plate 3 has two, and one is used to be connected and fixed wall body 1, its two, will import heat-exchanging chamber 12 inside from advancing the flue gas that mouth 5 enters, reducing smoke flow velocity, and prolong smoke stroke, the uniform distribution flue gas flow direction improves the thermal absorptivity of adopting heat pipe 13.
According to the specification difference of supporting boiler, the form that the is provided with difference of hot-air channel 7, for large-sized boiler, the form that is provided with of the hot-air channel 7 of this device is shown in Fig. 3,4, the longitudinal component of hot-air channel is near wall body 1 one sides.This form helps strengthening as required the space of hot-air channel.
For miniature boiler, the form that is provided with of the hot-air channel 7 of this device as shown in Figure 1, 2, this form has good heat insulating, the characteristics that heat utilization ratio is high because the longitudinal component of hot-air channel is surrounded by heat-exchanging chamber 12.
As shown in Figure 5, when using the utility model, the exhaust opening of boiler 18 is connected with the mouth 5 that advances of this device, will be transported in the Slag Room 19 of boiler 18 from the hot-air that this device goes out air scoop 14 discharges by pipeline.Fill with water in the scarfing cinder pond 17 below Slag Room 19, with the gap closing between Slag Room 19 and the scarfing cinder pond 17.
The high-temperature flue gas of discharging from boiler 18 exhaust openings enters the heat-exchanging chamber 12 from the mouth 5 that advances of this device, through after the heat exchange from outlet flue 11 dischargings.Normal temperature air is through entering air chamber 8 from air inflow adjusting blinds and air cleaner 10 from advancing air scoop 9, flowing through to adopt enters into hot-air channel 7 after heat pipe 13 is gathered heats again, and high temperature air goes out in the Slag Room 19 that air scoop 14 is discharged to boiler 18 recycling from this device.
