Technical Field
The utility model relates to a boiler structure field especially relates to a steam generator and steam generator.
Background
The steam generator needs to generate enough steam during heating, and the conventional steam generator only depends on heating to vaporize liquid water, so that the vaporization effect is poor. In order to increase the steam generation rate, it is only possible to increase the heating amount, increase the volume of the equipment and reduce the flow rate of water, but the above method needs to increase the manufacturing or using cost of the steam generator. Therefore, a steam generating device which can improve the steam generation rate and has simple structure and low cost is lacked at present.

the steam generating device comprises a heating pipe and a throttling device, wherein the heating pipe comprises a steam generating part, one end of the steam generating part is communicated with the throttling device, and the other end of the steam generating part is communicated with a steam outlet. The throttling device can reduce the flow of water before the water enters the steam generating part, so that the pressure of the water after the water enters the steam generating part is reduced, the water is more easily vaporized, and the steam generation rate is improved.
Preferably, the throttle device is provided with a throttle hole. The throttling hole can throttle water to reduce the pressure of the water, meanwhile, the water is changed into separated water drops after passing through the throttling hole in a spraying mode, the heat exchange efficiency with the surrounding high-temperature environment is improved, and the water is more easily vaporized.
Preferably, the throttling device is a plate with a throttling hole arranged in the heating pipe. The throttling device is directly arranged in the heating pipe, so that the equipment space is saved, and the manufacturing cost and the processing difficulty are both lower.
Preferably, a pressure reducing part is arranged between the throttling device and the steam generating part. The pressure reducing part can further reduce the pressure of water flow in the heating pipe, so that the water is reduced in pressure and is more easily vaporized after passing through the throttling hole.
Preferably, the pressure reducing part is formed by bending a heating pipe. The bending form can increase the flow resistance of water flow and reduce the flow speed, so that the flow speed is lower after the water flow reaches the steam generation part, and the water pressure is correspondingly reduced.
Preferably, fins are provided on the outer side of the steam generating part. The fins can more fully absorb heat within the combustion chamber.
Preferably, the heating pipe is provided with a preheating part, and the throttling device is arranged between the steam generating part and the preheating part. The preheating part can heat the water flow before the water flow enters the steam generating part, so that the water temperature approaches the critical temperature of vaporization, and the steam generating rate of the steam generating part is further improved.
Preferably, fins are arranged on the outer side of the preheating part. The fins can more fully absorb heat within the combustion chamber.
A steam generator comprises the steam generating device.
The utility model discloses following beneficial effect has:
1. the throttling device reduces the pressure of water flow entering the steam generating part, improves the vaporization rate of the generator, has simple structure and low manufacturing cost, and can still have higher steam generation rate under the conditions of not increasing the heating quantity of the steam generator and not increasing the volume of equipment;
2. the throttling device can increase the contact area of water flow and the surrounding environment in a spraying mode, so that the water flow is more easily heated and vaporized, and the steam generation rate is further improved;
3. the preheating part can initially heat water flow, so that the water enters the steam generating part after the water temperature rises, and the vaporization rate of the generator is further improved.
