Preferably, the smoke evacuation pipe is of conical design.
The utility model has the advantages that: the utility model discloses simple structure, the pipe of will discharging fume locates the inside water that makes the pipe of discharging fume heat the pot internal portion of pot, and then improve the heat utilization efficiency, design the bottom of the pot body as hemispherical structure or bowl form structure, thus increase heat transfer area, improve the thermal efficiency, set up the water storage cavity in the pot body and preheat the cavity in addition, make the boiler produce steam fast, do not influence the use of steam, do not need to heat in advance, unlike traditional steam boiler need a large amount of time to go out steam, the practicality is strong; most importantly, the waste hot gas generated in the combustion process is temporarily stored by the waste hot gas temporary storage bin, and the heat contained in the waste hot gas preheats the water in the water storage tank, so that the water can be quickly vaporized in one step underwater; the secondary utilization of the waste hot gas is realized, the waste is reduced, and the cost is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1, a high-efficiency energy-saving steam boiler comprises a boiler body 1, a water storage cavity 2 is arranged in the boiler body, and a combustion chamber 3 is arranged below the boiler body, and is characterized in that: a smoke exhaust pipe 4 of the combustion chamber extends to the outside of the pot body from the lower bottom of the pot body through the water storage cavity, a waste hot gas temporary storage bin 5 is arranged on the smoke exhaust pipe extending to the outside of the pot body, a steam outlet 6 is arranged at the upper end of the pot body, the lower bottom of the pot body is of an upward convex hemispherical or bowl-shaped structure, a preheating chamber 8 is divided at the lower end of the water storage chamber through a partition plate 7, the preheating chamber extends to a steam outlet at the upper end of the pot body through a steam exhaust pipeline 9, a through hole 10 is arranged on the partition plate, a first valve 11 for communicating the preheating chamber with the water storage chamber is arranged at the through hole, a water storage tank 12 is arranged in the waste hot gas temporary storage bin, the water storage tank is characterized in that a water guide pipe 13 is arranged at the lower end of the water storage tank and connected with the water storage cavity, a second valve 14 is arranged on the water guide pipe, and a water inlet pipe 15 connected with a water source is arranged at the right end of the water storage tank.
Preferably, rollers 16 are connected to the lower part of the pot body.
