The utility model is the opposite making according to the heating radiator principle, and heating installation the inside is a hot water, makes the atmosphere temperature rising of outside, and the utility model to be the flue gas of heat pass through internally, through storage smoke-box, heat pipe, the water of outside is heated up.Perhaps directly use chimney as heat pipe, wrap up chimney, the water in the casing is heated up with casing.
The utility model is a flue gas waste heat recovery apparatus, it is fuel oil, coal, gas boiler special equipment, be installed in boiler mouth or the flue, can absorb the most of heat in the flue gas, improved temperature with its water that exchanges mutually, demand according to the user can be used as boiler replenishing water or domestic water, be the fuel saving expense like this, reduce production costs, reduce toxic emission, energy-conserving and environment-protective kill two birds with one stone again, removed the part incrustation scale simultaneously, reduce hardness of water, when making boiler replenishing water, prolonged the service life of boiler
The beneficial effects of the utility model are, by the heat energy recycle of this device with waste, are to improve energy utilization rate, reduce production costs, and one of means that the protection environment is direct, the most economic have reached energy-conservation, consumption reduction, the purpose of environmental protection.Soften hardness of water simultaneously, improved the service life of boiler.
Description of drawings
In conjunction with the accompanying drawings and embodiments the utility model is further specified down with novel face.
Fig. 1 is the utility model structural representation.
Among the figure, 1. casing, 2. water inlet, 3 advance mouth, 4. thermometer, 5. water yield indicator tube, 6. outlet flue, 7. delivery port, 8. precipitation switch, 9. gap, 10. standby joint, 11. support columns, 12. heat pipes, 13. storage smoke-boxes.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, it has a top is cylindrical, the bottom is conical casing 1, be respectively equipped with water inlet 2 and gap 9 on the top of casing 1, water inlet 2 is connected with running water pipe, water filling in casing 1, gap 9 make unnecessary water excessive in the time of can preventing still intaking after sealing is expired, in order to avoid the excessive damage equipment of hydraulic pressure.Bottom, side at casing 1 then is provided with delivery port 7, in order to discharging the water after the heating, it can the connecting pipe pump when being used as boiler replenishing water, and tubing pump connects check-valves again, the check-valves outlet links to each other with the boiler feedwater mouth, so just the heat of high-temperature flue gas can be fully utilized.For ease of the water level in the observation casing 1, (the waterline position of She Dinging as required) installs water yield indicator tube 5 in appropriate location, top, casing 1 side, in order to observe water level, Yi Bian take the respective handling measure, discharges water or intakes.For the water temperature in the observation casing 1, thermometer 4 also is installed on casing 1, its position can arbitrarily be provided with as required, is principle not influence to use.Be provided with sedimentation switch 8 in casing 1 conical lower section, can in time discharge in the time of impurity such as incrustation scale can occurring after water heating, the one side influence is normal to be used.The cylindrical lower portion side of casing 1 also has standby joint 10, can connect standby joint (as being used as the heating installation feedwater, bathing pool feedwater or the like) according to the domestic water needs, installs and uses simultaneously with delivery port 7.。
At the casing 1 built-in high-temperature flue gas harvester that is equipped with, this device comprises two storage smoke-boxes 13 up and down, the storage smoke-box 13 of top links to each other with the boiler outlet flue, and the outlet flue 6 of bottom storage smoke-box 13 links to each other with deduster, and two 13 of storage smoke-boxes pass through many heat pipes 12 and are communicated with.Store up smoke-box 13 above high-temperature flue gas enters successively like this, discharge from issuing storage smoke-box 13, can constantly heat the water in the casing 1 in the whole process, thereby thermal energy storage is got off for other place uses through heat pipe 12.The quantity of heat pipe, casing, the storage smoke-box, the size of heat pipe all is to decide according to the size of boiler
In use, at first want flushing cisterns body inside, owing to reasons such as manufacturing, transportation, storage, installations, can leave over oxide skin, welding slag and other construction foreign material in this equipment box, to ensure the safe operation of this equipment, next checks water yield indicator tube 5, thermometer 4, water inlet 2 advances mouth 3, outlet flue 6, delivery port 7, precipitation switch 8, whether the sealing of standby joint 10 is intact, checks whether the motor circuit meets national electricity consumption regulation and whether check-valves uses correctly.
This equipment belongs to non-pressure vessel, can give the feedwater of this equipment with running water, and when feedwater, water yield indicator tube arrives the top and gets final product.Connect standby joint when being used as domestic water as required.When boiler normally uses, its flue gas this waste-heat recovery device of flowing through, the conductive force by heat pipe and storage smoke-box raises water temperature, can in time give boiler replenishing water.In time being full of casing after finishing to boiler feedwater gets final product.
Concrete structure of the present utility model is not limited in above-mentioned example.For this equipment, the position of its water inlet 2 is except that the top that is arranged on casing 1, and the position that also can be arranged on its side or bottom or other convenient water inlets gets final product.Outlet flue 6 also is to adjust interface as required with the position of advancing mouth 3 simultaneously, such as they can be all in top or the bottom or the side of casing 1, also can distinguish top and the bottom or top and side or various ways such as bottom and side, can store up the water in the circulation heating casing 1 in the smoke-boxes 13 two as long as guarantee high-temperature flue gas, if boiler is bigger simultaneously, storage smoke-box 13 quantity can be increased to three or four or more.And the also replaceable pipeline that becomes an independent smoke pipe or other Gong high-temperature flue gas to circulate of two storage smoke-box 3 and the heat pipes 12 that are communicated with their.Fell if it is crossed about might not being in the position of storage smoke-box 13, about the position of storage smoke-box is exactly.Not necessarily circular cone is capable in the bottom of casing 1 could collect incrustation scale, if handle assembly just crosses all circles, have one higher slightly, the precipitation switch is installed in the bottom, also can emit incrustation scale.The quantity of support column 11 is unfixed, can adjust as required.
