These features of the present utility model and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment mono-;
Fig. 2 is the connection diagram of flow disturbing cover and smoke-intake pipe in embodiment bis-;
Fig. 3 is the structural representation of flow disturbing cover in embodiment bis-.
[specific embodiment]
The utility model provides a kind of steam generator, comprise coil pipe, burner, steam-water separator and watering, coil pipe is connected between steam-water separator and watering, and burner is provided with burner hearth, coil pipe is arranged in burner hearth, and burner hearth is provided with the smoke-intake pipe extending in coil pipe.Burner heating offers the flue gas of burner hearth, and flue gas enters the deaerated water heat exchange in burner hearth and coil pipe by smoke-intake pipe, and deaerated water adds the steam water interface of thermosetting certain pressure by coil pipe, then enter steam-water separator and carry out carbonated drink separation.
Compare boiler heating, coil pipe is carrying the process of deaerated water to heat deaerated water, and the volume of coil pipe is less than the volume of boiler, and the water in coil pipe flows, and water capacity is much smaller, without risk of explosion.The coefficient of heat transfer of coil heat exchange is high, and the unit thermic load of mobile deaerated water and flue gas heat exchange is large, and the efficiency of heating surface is high, and the speed of steaming is fast, and the heat of waste is little.
Accompanying drawing below in conjunction with the utility model embodiment is explained and illustrated the technical scheme of the utility model embodiment, but following embodiment is only preferred embodiment of the present utility model, not all.Embodiment based in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection domain of the present utility model.
Embodiment mono-:
With reference to figure 1, shown steam generator, comprises coil pipe 3, burner 1, steam-water separator 2 and watering, coil pipe 3 is connected between steam-water separator 2 and watering, burner 1 is provided with burner hearth 4, and coil pipe 3 is arranged in burner hearth 4, and burner hearth 4 is provided with the smoke-intake pipe 41 extending in coil pipe 3.After flue gas and burner 1 heat exchange, by smoke-intake pipe 41, enter burner hearth 4 and carry out heat exchange with coil pipe 3, the deaerated water of watering is squeezed into coil pipe 3 by water pump, deaerated water in coil pipe 3 in mobile process by flue gas, form the mixture of steam and water, steam-water separator 2 is separated by both, and steam is sent to gas utilization unit from the steam (vapor) outlet 21 of steam-water separator 2 upper ends, and high-temperature water can flow to deoxygenation water tank by discharge outlet 22 soft water is carried out to heat exchange deoxygenation.
The axial short transverse setting along burner hearth 4 of coil pipe 3 in the utility model, the upper end of coil pipe 3 is provided with water inlet 31, water inlet 31 connects watering, the lower end of coil pipe 3 sets out the mouth of a river 32, delivery port 32 connects steam-water separator 2, the bottom of burner hearth 4 arranges smoke-intake pipe 41, the top of burner hearth 4 is provided with outlet flue 42, the flue gas of high temperature flows from the bottom up in burner hearth 4, fluid in coil pipe 3 flows from top to bottom, so the fluid in coil pipe 3 and flue gas generation heat convection, ordinary hot exchange relatively, the efficiency of heat convection is high, faster the water in heat(ing) coil.The high-temperature flue gas heat exchange of the bottom of coil pipe 3 and bottom, the top, bottom of coil pipe 3 and the flue gas heat exchange of lower temperature, so the temperature of coil pipe inner fluid contact raises gradually, exit reaches the highest temperature, has rationally reduced hot loss of energy.
Wherein coil pipe 3 comprises wrong row's convection current coil pipe, in convection current coil pipe, between adjacent two ring ducts, keep certain distance, flue gas is through out-of-date, flue gas is had to perturbation action, can improve flue gas Reynolds number, form disorderly, irregular turbulence flow flied, and in wrong row's convection current coil pipe, conduit periphery contacts flue gas completely, increased heat exchange area, can reduce the exhaust gas temperature of outlet flue 42, using energy source effect improves.
