Abstract
A boiler energy saving device comprises a boiler body, a discharge flue and an air heat exchanger. A combustion chamber is formed in the boiler body. The discharge flue is arranged on one side of the combustion chamber, the upper portion of the discharge flue is communicated with the combustion chamber, and the bottom of the discharge flue is communicated with a discharge pipe. An induced draft fan is arranged on the discharge pipe. The air heat exchanger is disposed in the middle of the discharge flue, an inlet end of the air heat exchanger is connected with an air blower through a fan tube, and an outlet end of the air heat exchanger is communicated with the combustion chamber through a hot air outlet pipe. The boiler energy saving device is simple in design and remarkable in effect. Since the air heat exchanger is added in the discharge flue of the boiler body, waste gas, at the temperature of 150-180 DEG C, discharged from the discharge flue is utilized to preheat cool air which is supplied into the boiler by the air blower to 120 DEG C, and accordingly, coal combustibility is improved, load of the induced draft fan is reduced, and power consumption is lowered.
Description
Technical field
The utility model relates to a kind of energy-saving device of boiler.
Background technology
Production period outdoor temperature is generally below 10 ℃ in the winter time for coal-burning boiler, and particularly season severe winter, outdoor temperature was especially lower than 0 ℃, and air blast is blown into the cold air of boiler because temperature is too low, can reduce fire box temperature, affect burning of coal, thermal losses increases, and has increased fuel cost; And the flue dust temperature that boiler flue is discharged is up to 150-180 ℃, be not used and drain in vain, further increased the waste of fuel.
Summary of the invention
The purpose of this utility model is the problem existing for prior art, provides a kind of energy heater blower to be blown into the energy-saving device of boiler of burner hearth cold air temperature,
The technical solution adopted in the utility model is: a kind of energy-saving device of boiler, by body of heater, smokejack, air heat exchanger, formed, in described body of heater, be provided with combustion chamber, one side of combustion chamber is provided with smokejack, smokejack top and combustion chamber UNICOM, smokejack bottom and smoke exhaust pipe UNICOM, smoke exhaust pipe is provided with air-introduced machine, in the middle of described smokejack, be provided with air heat exchanger, described air heat exchanger inlet end is connected with air blast by air blower tube, and described air heat exchanger outlet side is by hot-blast outlet pipe and combustion chamber UNICOM.
The utility model beneficial effect: simplicity of design, effect is remarkable, in boiler exhaust gas road, increase an air heat exchanger, utilize the 150-180 ℃ of high-temp waste gas of discharging in smokejack, preheating drum blower fan is blown into the temperature of the cold air of boiler, can make cold air be preheating to 120 ℃ of above high temperature, has improved coal burning, alleviate air-introduced machine load simultaneously, reduce power consumption.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accompanying drawing is the utility model structural representation.
In figure: 1 body of heater, 2 combustion chambers, 3 smokejacks, 4 air blower tubes, 5 air heat exchangers, 6 air blasts, 7 hot-blast outlet pipes, 8 smoke exhaust pipes, 9 air-introduced machines.
The specific embodiment
A kind of energy-saving device of boiler as shown in the figure, by body of heater 1, smokejack 3, air heat exchanger 5, formed, in described body of heater 1, be provided with combustion chamber 2, one side of combustion chamber 2 is provided with smokejack 3, smokejack 3 tops and combustion chamber 2 UNICOMs, smokejack 3 bottoms and smoke exhaust pipe 8 UNICOMs, smoke exhaust pipe 8 is provided with air-introduced machine 9, in the middle of smokejack 3, be provided with air heat exchanger 5, air heat exchanger 5 inlet ends are connected with air blast 6 by air blower tube 4, and air heat exchanger 5 outlet sides are by hot-blast outlet pipe 7 and combustion chamber 2 UNICOMs.
