For achieving the above object, the utility model adopts following technical scheme:
The burn steam boiler of the dregs of a decoction, comprises;
Burner hearth, the inside of burner hearth has a combustion chamber, and the sidewall bottom of burner hearth offers an opening; Burner hearth outside is provided with water inlet pipe, steam output pipe and smoke exhaust pipe;
Be fixed on burner hearth and be positioned at the feed hopper of open outer side, this feed hopper top has a charge door, its side is provided with and the discharging opening of open communication near a side of opening, feed hopper is provided with a pressure fan to feed hopper inner blower away from the side of opening, is provided with a feed rotor in feed hopper inside between the air outlet of pressure fan and discharging opening;
Heat exchanger tube, this heat exchanger tube is positioned at the inside of combustion chamber, and its one end is communicated with water inlet pipe, and the other end is communicated with steam output pipe.
This steam boiler also comprises the deduster that is connected in smoke exhaust pipe outside, air-introduced machine and the chimney of order.
Deduster inside is provided with multiple spray heads, and the bottom of deduster is connected in water inlet pipe by pipeline, on the pipeline of connection water inlet pipe and deduster, is also provided with a filter.
The beneficial effects of the utility model are:
Than prior art, the utility model rotates owing to adopting pressure fan to blow feed rotor, realizes air and dregs of a decoction fuel is carried simultaneously, and can make air and dregs of a decoction fuel fully mix combustion chamber is inner, improve the efficiency of combustion of dregs of a decoction fuel, and simplified the structure of steam boiler.Meanwhile, the utility model can also reduce the discharge of harmful substance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 10, burner hearth; 11, combustion chamber; 12, opening; 13, water inlet pipe; 14, steam output pipe; 15, smoke exhaust pipe; 20, feed hopper; 21, feed rotor; 22, pressure fan; 23, charge door; 24, discharging opening; 30, heat exchanger tube; 40, deduster; 41, spray head; 50, air-introduced machine; 60, chimney; 70, filter.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, for the steam boiler of a kind of dregs of a decoction that burn of the present utility model, it comprises burner hearth 10, feed hopper 20, heat exchanger tube 30, wherein, burner hearth 10 inside have a combustion chamber 11, the sidewall bottom of burner hearth 10 offers an opening 12, and burner hearth 10 outsides are provided with one for connecting the water inlet pipe 13 at extraneous water source, for supplying with the steam output pipe 14 of steam to equipment and inner the combustion chamber of burner hearth 10 11 flue gas producing being drained into the smoke exhaust pipe 15 of external environment.
Feed hopper 20 is fixed on the bottom outside of burner hearth 10, and its bottom lock is provided with a discharging opening 24 near burner hearth 10 1 sides, and this discharging opening 24 is in the same size with the opening 12 of burner hearth 10, and after feed hopper 20 is fixed on burner hearth 10, discharging opening 24 overlaps with opening 12.The top of feed hopper 20 has charge door 23, and dregs of a decoction fuel particle adds from this charge door 23; Feed hopper 20 is provided with a pressure fan 22 away from the side of opening 12, the air outlet conducting of this pressure fan 22 is to the inner chamber of feed hopper 20, feed hopper 20 inside are provided with a feed rotor 21, this feed rotor 21 is between the air outlet and discharging opening 24 of pressure fan 22, in the time opening pressure fan 22, it not only can send into air to the combustion chamber of burner hearth 10 11 inside, can also blow feed rotor 21 rotates simultaneously, the rotation through feed rotor 21 from charge door 23 adds of dregs of a decoction fuel particle is carried, and after mixing fully, enters into combustion chamber 11 with air.Heat exchanger tube 30 is positioned at the inside of combustion chamber 11, and its one end is communicated with water inlet pipe 13, and the other end is communicated with steam output pipe 14, and the cold water that water inlet pipe 13 is carried forms steam after being heated rapidly in combustion chamber 11 inside, exports from steam output pipe 14.
