This utility model opens wide type heat exchanger and packed tower convolution normal pressure straight-heating boiler, with capacity operation and low work(
Rate runs two kinds of operational modes, can be selected according to different operating modes.Wherein：
During capacity operation：Frequency conversion burner 1 run before, it is desirable to the preset water level liquid level in water tank 4 do not had combustion barrel 3 and
Heat-exchanging tube bundle 5 and it is not less than minimum warning line；Water inlet pipe 13 is intake, and frequency conversion burner 1 starts and is gradually incremented by by low-power
To total power burning；Combustion product gases carry out heat exchange along combustion barrel 3 and heat-exchanging tube bundle 5 with the water in water tank 4, and this process is commutative
60%~80% (related to the length and quantity of combustion barrel and heat-exchanging tube bundle) of total burning capacity, water temperature is improved simultaneously in water tank 4
Produce some vapor；Flue gas carry remaining non-heat-shift by outlet set cylinder 15 discharge and with liquid level in water tank 4 on steaming
Vapour phase mixes, and mixed gas enters filler 7 upwardly through filler grid 6, enters with the shower water from upper spray pipe group 9
Row heat and mass exchange, the commutative flue gas after-heat of this process more than 90% and remove most of steam；Flue gas continues
Upwards final heat transfer is carried out with condensing tube group 10, residual steam can be condensed and reentered in filler 7 by this process；Flue gas Jing
The wire mesh demister 11 crossed in chimney 12, remove flue gas entrainment remaining mist, finally from chimney 12 discharge low temperature, drying,
The flue gas of cleaning.
While said process is carried out, water inlet is preheated by condensing tube group 10, is sprayed by the transmission of shower group 9
Spill, heat exchange is carried out and into water tank 4 with above-mentioned flue gas and the mixing hot gas of steam in filler 7；Water inlet in water tank 4 to
The direction of outlet pipe 2 is advanced, and heat of continuous absorption heat-exchange tube bank 5 and combustion barrel 3, carries eventually through outlet pipe 2 during this
Supply user.
During low power run：In normal operation, because the reason such as reduction of user's water consumption causes inflow to subtract
Few, the Parameters variation feeds back to frequency conversion burner 1 by feed water flow gauge (not shown) so as to reduces combustion intensity and presses
Actual inflow adjusts flame, reaches and matches with inflow.Now combustion product gases are conducted by combustion barrel 3 and heat-exchanging tube bundle 5
Energy account for more than the 90% of total amount of heat, after-heat is swapped with flue gas in filler 7 and condensing tube group 10.Due to filler reality
Border usage amount is 1.5~2 times of calculated value, increases the heat and mass time, and low inflow is sufficient for after-heat
Exchange.
Water level is less than warning liquid level in the water temperature in water tank 4 exceedes warning water temperature or water inlet wretched insufficiency causes water tank 4
When, temperature monitoring probe and water level monitoring probe feedback data, frequency conversion burner 1 quits work, until restarting.
This utility model opens wide type heat exchanger and packed tower convolution normal pressure straight-heating boiler, has the characteristics that：Energy-conservation：Change
The thermal efficiency can reach 95%~98%, 20~60 DEG C of flue gas exit temperature (different according to inflow temperature)；Environmental protection：Exiting flue gas
Low temperature, drying, cleaning, discharge the requirement that numerical value meets national standard；Overall ease for use：Avoid building in addition water tank (in water tank
With can cause thermal loss in the transmission of boiler), globality be more convenient for routine use, safeguard；Adaptability：Adapt to different quality,
It is insensitive for water hardness；The suitability：Suitable for the various operating modes such as heating, bathing；Safety：Various monitorings and feedback system
Automatic running can be carried out according to Monitoring Data, it is safe and reliable.
Although above with general explanation and specific embodiment having made detailed description to this utility model,
On the basis of this utility model, it can be made some modifications or improvements, this is to those skilled in the art apparent
's.Therefore, the these modifications or improvements on the basis of without departing from this utility model spirit, belonging to this utility model will
Seek the scope of protection.
