Low-voltage high-temperature automatic energy saving steam boiler is made of boiler body system and automatic water-storage injector system two parts as shown in drawings.
Wherein said boiler body system comprises: body of heater (22), combustor sub-assembly (17), Pressure gauge (1), smoke exhaust pipe (2), automatically controlled instrument box (24), safety valve (27), superheated steam Wen Xianbiao (28) and level sensor (9) etc.Described automatic water-storage injector system comprises water storage box (32), water pump assembly (33), check-valves (34), water level displaying tube (40), water source sensor (41) and inlet pipe, drain pipe etc.Maximum characteristics of the present utility model are in the inner chamber body of body of heater (22), are provided with a top vaporium (25) and water body chamber, bottom of being separated by steam division board (4); And at indoor three heat-exchanging chambers (10,8,5) that are provided with from bottom to top of described water body, directly crossing fire tube (6), (11) and S shape by several respectively between these three heat-exchanging chambers crosses fire tube (17) and is connected, make the heat energy that produces after the burner hearth burning, forward middle heat-exchanging chamber (8) down to by the supreme heat-exchanging chamber of heat-exchanging chamber (10) (5) under the burner hearth warp, finally aerial through smoke exhaust pipe (2) discharging, prolonged heat energy carries out heat exchange with water in water body time greatly; Greatly improve the utilization rate of heat energy.
Now work and the automatically controlled water filling program with this boiler is expressed as follows:
1. open the water source valve, allow running water or the tank water of drop is arranged, automatically pour in the water storage box (32) of boiler, when the water level of this water storage box (32) reach a certain height, under the effect of ball-cock assembly (31), will close water inlet, at this moment also can be by water level in water level displaying tube (40) the range estimation case of water storage box outer side edges.
2. connect power supply, and start the switch in the automatically controlled instrument box (24), make operating circuit be in opening state.
3. water filling water pump assembly (33) is started working, and boiler intracavity (23) is constantly injected in the source, water source in the water storage box (32), and the green indicator lamp of the demonstration water filling state in the automatically controlled instrument box is glittering at this moment.(in this injecting process, along with the interior water level of water storage box (32) descends, the ball-cock assembly (31) in its case also descends thereupon, and running water replenishes continuously, up to irritating to the working water level of furnace chamber, along with the rising and the outer water source of cut-out of water storage box water level.)
4. cut off the water supply in the external world, when water storage box was anhydrous, water source sensor (41) can not signal spread out of with starting in the water storage box, water pump assembly and combustor sub-assembly also can't start.
5. when the water level in the boiler is annotated certain altitude, the probe in the level sensor (9) passes to the electric-controlled switch of water pump assembly (33) with signal, and water pump assembly is quit work.
6. the out-of-work while of water pump assembly, burning unit (17) also receives the signal of startup work, and the blower fan of combustor begins to start air-supply, and the electroceramics electrode begins sparking; Begin the Residual oil molecule in the stove is discharged, prevent prominent sudden and violent; The motor electroceramics valve of combustor oil pump is opened atomizer commencement of fuel injection, ignition automatically after 10 seconds.(under the unsuccessful state of igniting for the first time, when the electric eye of combustor can not pass to combustor with the burning signal, the combustor autostop, atomizer also stops oil spout automatically simultaneously.The oil pump magnetic valve also cuts out automatically.This moment, operating personnel can press the electric-controlled switch startup of combustor with hand.)
7. boiler startup, when entering the normal combustion state, when vapour pressure reached design limit pressure, pressure controller can be passed to signal the burning unit, this unit stove of can autostop having a rest.When the steam pressure in the boiler was lower than qualification pressure, pressure controller passed to combustor with signal; This chance is started automatically, makes boiler guarantee the normal pressure delivering vapor.
8. when the water in the boiler was evaporated to the qualification low water level, the low-level probe in level sensor this moment (9) spread out of signal water pump assembly is started, supplementary water injection in boiler; Autostop is cut off the water when arriving certain altitude, and so going round and beginning again constantly produces steam.
9. when water level in the boiler surpassed lowest water level and peak level, the peak level probe and the lowest water level probe of level sensor can send signal, and the work of burn-out machine is to guarantee the safe operation of boiler.
In the Actual combustion process, bending pipe and hearth wall that flame one side heat in the burner hearth (13) is penetrated furnace bottom and bottom acutely seethe with excitement stove inner bottom part water, beginning heat is transmitted, simultaneously again by and following heat-exchanging chamber (10) and burner hearth between the some straight fire tube (11) of crossing enter down heat-exchanging chamber (10), and in the time of heat-exchanging chamber (10) stop down, make straight fire tube (11) and the peripheral water body of heat-exchanging chamber (10) in the furnace chamber carry out the heat exchange second time; When treating down that the interior heat energy of heat-exchanging chamber (10) gathers certain space, cross fire tube (7) along S shape again and rise to switch room (5), these heat energy bodies in uphill process for the third time with the water body generation heat exchange of furnace chamber (23), the heat energy body also rises to heat-exchanging chamber (5) again, finishes the 4th heat exchange; In heat-exchanging chamber on this (5), the heat energy body carries out heat exchange to the water body in the furnace chamber on one side, Yi Bian again the spiral steam output pipe of being located in the heat-exchanging chamber is carried out heat exchange; After this, the temperature of heat energy body sharply descends again along with the promotion of combustor blast, and the straight fire tube (6) of crossing along its underpart enters middle heat-exchanging chamber (8), carries out the 5th heat exchange with water body in the furnace chamber; Finally aerial through smoke exhaust pipe (2) discharging.
Just because of five heat exchanging process so, greatly prolonged the heat exchange of heat energy body in stove, also this five heat exchanging process have just been eliminated light oil in combustion process, the high-decibel voice that produces because of the whirlwind effect.Make this boiler that bigger heat energy utilization rate and the anti-pollution effect that abates the noise be arranged.
