Description
Technical field
The utility model relates to a kind of fuel oil or gas-steam boiler, particularly relates to the high-efficiency steam boiler with flue gas waste heat utilization device.
Background technology
Fuel oil or gas-steam boiler have because of it during advantages such as energy-conservation, efficient, safe ready are widely used in daily life and produce, the high-temperature flue gas that the fuel oil of burner ejection or combustion gas generate at stove chamber inner combustion flows in heat exchange smoke pipe by smoke box, high-temperature flue gas is discharged from exhaust opening after the heat exchange smoke pipe of flowing through, in the heat exchange smoke pipe of flowing through, high-temperature flue gas carries out heat exchange by outer surface and the cold water in body of heater of heat exchange smoke pipe, cool water heating is become to steam, finally by jet chimney, be transported to each application scenario.Existing common steam boiler, the tail gas that its exhaust opening is discharged conventionally also has certain temperature, and directly energy had both been wasted in discharge, and the tail gas of discharge also affects air quality.
Utility model content
For overcoming above-mentioned defect, the utility model aims to provide a kind of tail gas that utilizes and the cold water entering in boiler furnace is carried out to preheating, the high-efficiency steam boiler of raising the efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high-efficiency steam boiler, comprise body of heater, described body of heater is connected with a burner, the top of described body of heater has an exhaust opening, and described exhaust opening top is provided with a waste-heated water-tank, and described waste-heated water-tank has a water inlet pipe and an outlet pipe, described water inlet pipe is connected with water source, and described outlet pipe is connected with in body of heater.
Described waste-heated water-tank comprises the water tank of a sealing, is provided with the some tail gas smoke pipes that vertically distribute in described water tank, and the bottom of described tail gas smoke pipe is connected with the heat exchange smoke pipe of body of heater inside, and the upper end pass-out of described tail gas smoke pipe is in water tank.
Described waste-heated water-tank's top is provided with an exhaust gas cleaner, and the top of described exhaust gas cleaner is provided with a rain cover.
Described waste-heated water-tank's upper end is also provided with a logical air pipe.
Described waste-heated water-tank's bottom is also provided with a dewatering orifice.
Adopted high-efficiency steam boiler of the present utility model, utilize waste-heated water-tank to carry out waste heat recycling to the tail gas of discharging in boiler, the thermal efficiency of boiler is improved greatly, by exhaust gas cleaner, last tail gas is purified again, reduced the pollution of emission gases to atmosphere simultaneously.

In figure: 1-body of heater, 2-burner, 3-exhaust opening, 4-waste-heated water-tank, 5-water inlet pipe, 6-outlet pipe, 7-water tank, 8-tail gas smoke pipe, 9-exhaust gas cleaner, 10-rain cover, 11-leads to air pipe, 12-dewatering orifice.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of high-efficiency steam boiler, comprise body of heater 1, described body of heater 1 is connected with a burner 2, the top of described body of heater 1 has an exhaust opening 3, the high-temperature flue gas of burner 2 ejection flow through burner hearth, heat exchange smoke pipe in body of heater 1, finally from exhaust opening 3, discharge, high-temperature flue gas is when the burner hearth of flowing through, heat exchange smoke pipe, carry out heat exchange with the cold water in body of heater 1, make the cool water heating in the body of heater 1 of high pressure become steam, in sum, basically identical with existing common steam boiler structure form.
The innovative point of high-efficiency steam boiler of the present utility model is mainly that described exhaust opening 3 tops are provided with a waste-heated water-tank 4, described waste-heated water-tank 4 has a water inlet pipe 5 and an outlet pipe 6, described water inlet pipe 5 is connected with water source, and described outlet pipe 6 is connected with in body of heater 1.Water source cold water is out flowing into waste-heated water-tank 4 after pretreatment, after preheating by waste-heated water-tank 4, become again in warm water water flowing body of heater 1, like this, warm water in body of heater 1 and burner hearth, heat exchange smoke pipe carry out the time that heat exchange becomes high-temperature steam and can greatly shorten, and have improved the thermal efficiency of boiler.
As shown in Figure 2 and Figure 3, described waste-heated water-tank 4 comprises the water tank 7 of a sealing, in described water tank 7, be provided with the some tail gas smoke pipes 8 that vertically distribute, the bottom of described tail gas smoke pipe 8 is connected with the heat exchange smoke pipe of body of heater 1 inside, and the upper end pass-out of described tail gas smoke pipe 8 is in water tank 7.According to actual conditions, conventionally the number of tail gas smoke pipe 8 can be identical with the number of heat exchange smoke pipe and corresponding one by one, be every heat exchange smoke pipe respectively tail gas smoke pipe 8 be corresponding thereto connected, cold water in high-temperature tail gas in tail gas smoke pipe 8 and waste-heated water-tank 4 carries out becoming warm water after heat exchange, then becomes high-temperature steam by again carrying out heat exchange with burner hearth, heat exchange smoke pipe in outlet pipe 6 inflow bodies of heater 1.
For making the tail gas finally entering in atmosphere reach discharge standard, another innovative point of high-efficiency steam boiler of the present utility model is that described waste-heated water-tank's 4 top is provided with an exhaust gas cleaner 9, and the top of described exhaust gas cleaner 9 is provided with a rain cover 10.At the tail gas of the tail gas smoke pipe 8 rear discharges of flowing through, after the purification through exhaust gas cleaner 9, reach discharge standard completely, avoided the pollution of tail gas to atmosphere.
