The specific embodiment
Shown in accompanying drawing 1, the present embodiment comprises controller 6, blower fan 1, condensing heat exchanger 2, captation 3, condensing heat exchanger 2 is contained in captation 3, blower fan 1 is electrically connected to controller 6, also comprise the ultrasonic humidifying module 5 being connected with captation 3 bottoms or bottom, in the present embodiment, ultrasonic humidifying module 5 is arranged on the bottom of captation 3, and ultrasonic humidifying module 5 is electrically connected to controller 6.
As shown in Figure 4, described ultrasonic humidifying module 5 comprises shell 51, atomizing piece 53, atomizing piece sealing ring 54 and circuit board 55, sheet 53 is arranged in shell 51, the condensed water of captation 3 bottoms is gathered on atomizing piece 53, atomizing piece sealing ring 54 is arranged on atomizing piece 53 and circuit board 55 junctions, prevent that condensation flow is to circuit board 55, the condensed water after circuit board 55 energising work on atomizing piece 53 is pulled out away from the water surface and produces water smoke.
Further, described ultrasonic humidifying module 5 also comprises the body seal circle 52 being positioned on shell 51, body seal circle 52 is for being tightly connected between ultrasonic humidifying module 5 and its installing component, as ultrasonic humidifying module 5 in the present embodiment is arranged on the bottom of captation 3, body seal circle 52 makes ultrasonic humidifying module 5 be connected with captation 3 sealed bottoms, prevents that condensed water from flowing out from the junction of the two.
Preferably, also comprise the liquid level detection device being connected with captation 3, liquid level detection device is electrically connected to ultrasonic wave module 5 or controller 6, in order to prevent that condensed water in captation 3 is from the smoke inlet main heat exchanger that flows backwards back, liquid level detection device is less than or equal to the floor level position of captation 3 smoke inlets.Monitoring by liquid level detection device to condensate water level, just opens or closes ultrasonic wave module when water level reaches certain position, can save electrical power consumed and can extend the service life of ultrasonic wave module 5 again.
Described liquid level detection device is liquid level sensor 9 or liquid-level switch 4, and described liquid level detection device is arranged in captation 3 or is arranged on outside captation 3, when being arranged on captation 3 when outer, need to be communicated with captation 3 by conduit 8.
Further, owing to containing the impurity such as dust in air and combustion gas, after burning and condensation, can to captation 3 bottoms, cannot discharge with condensation flow, so have the interface 10 that is connected to water heater bottom blow-down valve 7 at captation 3, the impurity blowoff valve 7 of can regularly outwarding winding is discharged to blowoff valve 7 by interface 10.
Operation principle: as shown in Figure 1, flue gas enters condensing heat exchanger 2 through captation 3 and carries out heat exchange, on condensing heat exchanger 2 surfaces, produce condensed water, condensing heat exchanger 2 has absorbed condensing water vapor latent heat, condensed water constantly produces and merges in captation 3, the condensed water of captation 3 bottoms contacts with ultrasonic humidifying module 5, when controller 6 monitors water level when enough high by liquid-level switch 4 or liquid level sensor 9, can control ultrasonic wave module 5 and carry out humidification, constantly the condensed water in captation 3 is cast aside to the water surface and produced water smoke, as water heater, working and water smoke can discharged through discharge flue, as water heater quits work, can control blower fans 1 by controller 6 and start and discharge water smokes or close ultrasonic wave module 5 and by the time open again ultrasonic wave module 5 during water heater working and discharge water smokes.As can be seen here, this condensing type water heater need not be that the discharge of condensed water increases a condensate pipe specially, easy for installation, elegant in appearance, greatly improves user's desire to purchase, accelerates the paces that China's propulsion energy-saving reduces discharging.
Referring to accompanying drawing 2, described liquid level detection device is liquid-level switch 4, liquid-level switch 4 is arranged in captation 3 and directly and is electrically connected in ultrasonic humidifying module 5, when controller 6 sends after humidification requirement to ultrasonic wave module 5, ultrasonic wave module 5 can be carried out humidification or stop humidification according to the situation of liquid-level switch 4 oneself, without controller 6, according to water level situation, controls whether humidification of ultrasonic wave module 5 again.
Referring to accompanying drawing 3, described level gauge is liquid level sensor 9, liquid level sensor 9 is arranged on the outer conduit 8 that passes through of captation 3 and is communicated with captation 3, liquid level sensor 9 is electrically connected to controller 6, and the water level that controller 6 monitors according to liquid level sensor 9 is controlled ultrasonic wave module 5 and whether blower fan 1 works.
In order to accelerate the atomization speed of captation 3 interior condensed waters, the quantity of described ultrasonic wave module 5 can be set to more than 2 as required, as 3,4,5 etc.
The maximum methane of generation condensed water of take is example, the thermal efficiency that the whole condensations of steam that fuel gas buring forms produce is 10.9%, general condensed type combustion gas water heater can only be cooled to condensed water 45% ~ 65% steam, and the thermal efficiency that condensed water produces is 4.9% ~ 7.1%.The water of 50 ℃ of take is example, its latent heat of vaporization is 2372kJ/kg, and ultrasonic humidifying technology is to utilize high frequency oscillation by dried up of water throwing and generation water smoke, rather than aquation is become to steam, very little 0.05 kW/ (kg.h) that only has so ultrasonic humidifying consumes energy, by the power consumption of unit conversion [0.05 kW/ (kg.h)=0.05*3.6MJ/kg=180kJ/kg] ultrasonic humidifying, only account for the 1/13(180/2372 ≈ 1/13 of the latent heat of vaporization), on whole thermal efficiency impact very little [(4.9% ~ 7.1%)/13=0.38% ~ 0.55%], so do not have, do not worry that ultrasonic humidifier can be the Efficiency Decreasing of condensing type water heater.Condensed water is cast aside the water surface and is produced water smoke by ultrasonic wave, then is discharged through smoke exhaust pipe by blower fan 1, thereby reaches the object that need not arrange specially condensed water.
With 20kW, with the condensed type combustion gas water heater of methane, calculate, according to chemical equation:
CH
4+ 2O
2=CO
2+ 2H
2o, the about 2m of condensed type combustion gas water heater of 20kW
3methane produce 4m
3steam, by 65% water vapor condensation Cheng Shui, the quality of condensed water is: (36/16) is * 65% ≈ 2.1 (kg/h) (2*0.7174), ultrasonic humidifying power is 2.1*0.05 ≈ 0.105kW, and the ultrasonic humidifier that is equipped with 105W just can solve the condensed water elimination problem of a 20kW condensed type combustion gas water heater.
