Abstract
The utility model discloses a gas heater water-wheel axial fan arranged inside the flue channel or the air channel of the gas heater by utilizing the driving of the water power. The shell(1) takes a column, one end of which is provided with a water inlet(2), while the other end id provided with a water outlet(9). The tap water enters into the shell(1) cavity to drive the vane(4) of the axial water turbine to rotate before entering into the heat interchanger. One end of the main shaft extends from the center of the other side end cover(8) of the shell, while a vane wheel(13)of the axial fan is fixed on the top of the shell through a nut(14). The shaft(3) rotates to drive the vane wheel(13)of the axial fan to move which boosts the pressure of the air, thereby making the smoke gain the energy which is exhausted from the flue channel.
Description
Affiliated technical field
The utility model relates to a kind of axial-flow blower that utilizes hydro powered, the gas water-heater water wheel axle flow fan that especially utilizes tap water pressure head potential energy to be used as power.
Background technique
At present, the mode that flue gas formula gas water-heater discharges flue gas is discharged in known pressure two kinds: a kind of is with a motor-driven gas fan air to be boosted to send into to enter heat exchanger after burner and combustion gas mixing are burnt and tap water carries out heat exchange, discharges from flue again; Another kind is with a motor-driven induced draft fan flue gas to be boosted the back from the flue discharge behind heat exchanger, and the shortcoming of this dual mode is to consume electric energy.
Summary of the invention
Discharge flue gas formula gas water-heater at existing Strong system and flue gas is discharged the shortcoming that needs consumed power, the utility model provides a kind of hydro powered water turbine to drive the gas water-heater water wheel axle flow fan of draught fan impeller rotation, can be discharged to the flue gas of gas water-heater outdoor through gas exhaust duct.
The utility model solves the scheme that its technical problem takes: the cylindrical shell of cylinder type is fixed on the inwall of air channel or flue with supporting rib, the cylindrical shell two ends are established cylindrical shell water intake and cylindrical shell water outlet respectively, the preceding elder generation of heat exchanger that tap water enters gas water-heater enters cylinder lumen pushing shaft flow water turbine impeller drive main axis rotation from the cylindrical shell water intake, flow out the heat exchanger that enters gas water-heater from the cylindrical shell water outlet again, main shaft stretches out from the opposite side end cap central position of cylindrical shell, the axial fan impeller is fixed on its end with nut, main axis rotation drives the rotation of axial fan impeller boosts air-flow, makes flue gas obtain the energy of discharging.The main shaft sliding supported condition, two sliding bearings are installed in the central position of a side end cap and opposite side end cap respectively, the seal arrangement sealing that the gap between main shaft and the opposite side end cap constitutes with sealed letter, seal ring and gland.
The beneficial effects of the utility model are to utilize the potential energy driving water turbine rotating band moving axis streaming draught fan impeller rotation of tap water pressure head that gas is boosted, and make flue gas obtain the energy of discharging, and do not consume electric energy.
