Abstract
The utility model discloses a waste heat recovery device for a boiler, which comprises the boiler, a chimney, a flue and a waste heat recoverer, wherein a water inlet of the boiler is communicated with a cold water pipeline, and the water outlet is communicated with a heat-supply pipeline; and a user water outlet pipeline is communicated with the boiler. The technical point is that the flue led from a smoke vent of the boiler is divided into a by-pass flue and a waste heat recovery flue through a three-way reversal valve, with the by-pass flue communicated with the inlet of an induced draft fan and the waste heat recovery flue communicated with the inlet of a smoke pipe; the waste heat recoverer consists a box body and an S-shaped smoke pipe in the box body; the outlet of the smoke pipe is communicated with the inlet of the induced draft fan through a pipeline; the outlet of the induced draft fan is communicated with the chimney; a user waste heat recovery water outlet pipeline is communicated with the box body; the box body is communicated with the boiler through a water return pipeline; and valves are arranged on the user water outlet pipeline and the user waste heat recovery water outlet pipeline. The waste heat recovery device has the advantages of simple and reasonable structural design, convenience in maintenance and fuel saving, and can effectively recover flue gas heat to achieve the purpose of energy saving.
Description
Technical field:
The utility model relates to a kind of energy saver of waste heat recovery recycling, is specifically related to a kind of boiler afterheat recovering device.
Background technology:
Boiler in use can produce a large amount of high-temperature flue gas, can waste a large amount of heat energy if directly emit, so people are with the heat recovery of waste-heat recovery device with high-temperature flue gas, and utilize again, but there is the shortcoming of recovering effect difference in present waste-heat recovery device, and the good waste-heat recovery device of indivedual recovering effect because of its complex structure, cost height, loaded down with trivial details, maintenance difficult be installed be difficult to promote.
Summary of the invention:
The utility model is intended to overcome the deficiencies in the prior art, and the boiler afterheat recovering device that a kind of reasonable in design, cost are low, be convenient to keep in repair, can effectively reclaim flue gas heat is provided.
Boiler afterheat recovering device of the present utility model, comprise boiler, chimney, smokejack and waste-heat recoverer, the water inlet of described boiler is communicated with cold line, delivery port is communicated with user's heat supply pipeline, user's water outlet pipeline is communicated with boiler, the technical scheme that adopts for achieving the above object is: the smokejack of drawing from the outlet flue of boiler is divided into bypass smokejack and waste heat recovery smokejack through three-way diverter valve, described bypass smokejack communicates with the entrance of air-introduced machine, described waste-heat recoverer is made of casing and the interior snakelike smoke pipe of leading thereof, described waste heat recovery smokejack communicates with the entrance of leading smoke pipe, the outlet of leading smoke pipe communicates with the entrance of air-introduced machine by pipeline, the outlet of air-introduced machine is communicated with chimney, user's waste heat recovery water outlet pipeline is communicated with casing, casing communicates with boiler by return piping, is provided with valve respectively on user's water outlet pipeline and the user's waste heat recovery water outlet pipeline.
The beneficial effects of the utility model are: this boiler afterheat recovering device, between smokejack and air-introduced machine, waste-heat recoverer is set, flow through snakelike in the waste-heat recoverer of high-temperature flue gas carried out heat exchange with the interior water of casing when leading smoke pipe, in the intensification current back boiler after heat exchange, thereby reduce quantity combusted, the saving resource of fuel, reach purpose of energy saving.When waste-heat recoverer needs repairing, can allow high-temperature flue gas flow to chimney, allow recirculation water directly flow back in the boiler by the bypass smokejack, in order to allow waste-heat recoverer quit work, and then conveniently it is keeped in repair.The utility model structural design advantages of simple, be convenient to the maintenance, can effectively reclaim flue gas heat.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with Fig. 1 the specific embodiment of the present utility model is described:
This boiler afterheat recovering device, comprise boiler 1, chimney 4, smokejack 6 and waste-heat recoverer, the water inlet of described boiler 1 is communicated with cold line 13, delivery port is communicated with user's heat supply pipeline 12, user's water outlet pipeline 14 is communicated with boiler, the smokejack 6 of drawing from the outlet flue of boiler 1 is divided into bypass smokejack 8 and waste heat recovery smokejack 7 through three-way diverter valve 11, described bypass smokejack 8 communicates with the entrance of air-introduced machine 3, described waste-heat recoverer is made of casing 2 and the interior snakelike smoke pipe 5 of leading thereof, described waste heat recovery smokejack 7 communicates with the entrance of leading smoke pipe 5, the outlet of leading smoke pipe 5 communicates by the entrance of pipeline with air-introduced machine 3, the outlet of air-introduced machine 3 is communicated with chimney 4, user's waste heat recovery water outlet pipeline 9 is communicated with casing 2, casing 2 communicates with boiler 1 by return piping 10, is provided with valve respectively on user's water outlet pipeline 14 and the user's waste heat recovery water outlet pipeline 9.
The cold water of cold line 13 enters in the boiler 1 by the water inlet of boiler 1, after boiler 1 heating, in the delivery port inflow user heat supply pipeline 12 by boiler 1, for the user heats.When carrying out waste heat recovery, regulating three-way diverter valve 11 makes smokejack 6 communicate with waste heat recovery smokejack 7, the high-temperature flue gas that boiler 1 produces enters through smokejack 6 and waste heat recovery smokejack 7 successively and leads in the smoke pipe 5, meanwhile close the valve on user's water outlet pipeline 14, open the valve of user's waste heat recovery water outlet pipeline 9, make water inflow casing 2 high-temperature flue gas interior and that lead in the smoke pipe 5 that reflux from the user carry out heat exchange, the water that heats up through heat exchange flows back in the boiler 1 by return piping 10, thereby reducing heating boiler is water intensification institute burnt fuel, and then reaches purpose of energy saving.The low-temperature flue gas of finishing after the heat exchange sucks in the chimneys 4 through air-introduced machine 3, and is discharged by chimney 4.When waste-heat recoverer needs repairing, regulating three-way diverter valve 11 makes smokejack 6 communicate with bypass smokejack 8, high-temperature flue gas is in bypass smokejack 8 and air-introduced machine 3 enter in the chimney 4, and by chimney 4 discharges, meanwhile open the valve of user's water outlet pipeline 14, close the valve of user's waste heat recovery water outlet pipeline 9, the water that refluxes from the user is directly flowed back in the boiler 1, just do not have high-temperature flue gas and water to pass through like this in the waste-heat recoverer, thereby be convenient to it is keeped in repair.
