If the specific posture changes, the directional indication will also change accordingly.

[0027] like Figure 1-Figure 6 As shown, a steam generating device comprises:

[0028] A furnace body 100, wherein a heating chamber is disposed in the furnace body 100, a heating source is disposed at one end of the furnace body 100, and the furnace body 100 includes a heating zone 101 and a preheating zone 102;

[0029] A smoke exhaust pipe 200, the smoke exhaust pipe 200 is located in the preheating zone 102 and communicates with the heating chamber;

[0030] The coil 103 is located in the heating chamber, and the water inlet of the coil 103 is arranged in the preheating zone 102, the water outlet of the coil 103 is arranged in the heating zone 101, and the water outlet of the coil 103 is provided with a steam-water separator 300, and the steam-water separator 300 is connected with a steam outlet pipe 307.

[0031] In this embodiment, the arrangement of the coil 103 in the furnace body 100 increases the amount of heated water as much as possible within the limited space of the furnace body 100, so that more steam can be generated; the heat source on the furnace body 100 generates hot air, which passes through the heating chamber and is discharged through the exhaust pipe 200, and the water inlet on the coil 103 is arranged in the preheating zone 102, that is, the water in the coil 103 will first absorb the heat of the preheating zone 102 (the waste heat of the exhaust flue gas), and then flow to the heating zone 101, absorb the heat generated by the heating source, improve the heating efficiency, and minimize the energy loss.

[0032] It is worth mentioning that the coil 103 refers to a hydrophobic pipe that is coiled multiple times on the same plane, and then the multiple coils 103 are interconnected to form.

[0033] It should be noted that one end of the furnace body 100 is connected to a gas pipe, so as to achieve open flame heating in the heating chamber.

[0034] Preferably, heat absorbing fins 104 are provided on the coil 103 located in the heating zone 101, and the heat absorbing fins 104 increase the contact area between the coil 103 and the surrounding medium (such as high-temperature flue gas or direct flame generated by combustion), thereby accelerating the heat transfer process from the heating source to the water.

[0035] Further preferably, the furnace body 100 includes an inner furnace 105 and an outer furnace 106, the heating chamber is located in the inner furnace 105, a first thermal insulation interlayer 107 is arranged between the inner furnace 105 and the outer furnace 106, and the first thermal insulation interlayer 107 is filled with thermal insulation material to minimize the heat loss in the furnace body 100.

[0036] Preferably, a circulating water tank 400 is further included, the water inlet of the circulating water tank 400 is connected to the water outlet of the steam-water separator 300 , and the water outlet of the circulating water tank 400 is connected to the water inlet of the coil 103 .

[0037] In this embodiment, in order to fully utilize energy, the liquid separated by the steam-water separator 300 is temporarily stored in the circulating water tank 400, and the liquid collected in the circulating water tank 400 flows to the water inlet of the coil 103. The liquid coming out of the oil-gas separator still has a certain residual temperature, which can reduce the heat required for boiling and absorb heat and boil faster.

[0038] It should be noted that the liquid in the circulating water tank 400 is used as a supplementary water source, and a direct water inlet is provided on the coil 103 for supplying water into the coil 103 .

[0039] Further preferably, the circulating water tank 400 is connected to the water outlet of the steam-water separator 300 via an inverted bucket drain valve 401 , so that only liquid enters the circulating water tank 400 .

[0040] Further preferably, the steam-water separator 300 is connected with a first sewage pipe 301 , the first sewage pipe 301 extends through the circulating water tank 400 , and the first sewage pipe 301 in the circulating water tank 400 is spirally arranged.

[0041] In this embodiment, the liquid discharged through the drain pipe also has temperature. In order not to waste this part of the temperature, a first drain pipe 301 on the steam-water separator 300 is arranged to be discharged after passing through the circulating water tank 400. The water in the circulating water tank 400 contacts the pipe wall of the first drain pipe 301 and absorbs the heat in the first drain pipe 301. The spiral arrangement increases the residence time of the liquid in the first drain pipe 301 in the circulating water tank 400.

[0042] Of course, a direct drainage pipe is also provided at the bottom of the circulating water tank 400, and when the internal pressure is too high, the internal water is directly discharged to the outside.

[0043] Further preferably, a second sewage pipe 302 is connected to the bottom of the steam-water separator 300 .

[0044] In this embodiment, the first sewage pipe 301 can provide heat to the circulating water tank 400, and the second sewage pipe 302 serves as a fuse to prevent the internal pressure of the steam-water separator 300 from being too high.

[0045] Further preferably, the water outlet on the steam-water separator 300 is connected to an inner drainage pipe 303, the inner drainage pipe 303 is located in the circulating water tank 400, two rows of first drainage holes 304 are arranged at the bottom of the inner drainage pipe 303, an outer drainage pipe 305 is sleeved on the outside of the inner drainage pipe 303, a closed drainage cavity is formed between the inner drainage pipe 303 and the outer drainage pipe 305, and a second drainage hole 306 is provided on the outer drainage pipe 305 and connected to the drainage cavity.

[0046] In this embodiment, the inner drainage tube 303 is located inside the circulating water tank 400 and directly receives the water from the steam-water separator 300. There are two rows of first drainage holes 304 at the bottom of the inner drainage tube 303. The function of these holes is to evenly disperse the water flow into the circulating water tank 400 to avoid impact caused by concentrated water flow, and also to help reduce bubbles in the water. The outer drainage tube 305 is sleeved on the outside of the inner drainage tube 303 to form a closed drainage cavity with the inner drainage tube 303. The water flowing out of the first drainage holes 304 first enters the drainage cavity, and then flows into the circulating water tank 400 through the second drainage holes 306 on the outer drainage tube 305. Such a double-layer tube design helps to control the direction of the water flow and increase the path length of the water before entering the water tank, thereby more effectively removing air or tiny bubbles entrained in the water.

[0047] Further preferably, the circulating water tank 400 includes an outer box 402, an inner box 403 is arranged inside the outer box 402, a second thermal insulation interlayer 404 is arranged between the inner box 403 and the outer box 402, a thermal insulation material is arranged inside the second thermal insulation interlayer 404, and a water storage cavity is arranged inside the inner box 403 to minimize the loss of heat in the circulating water tank 400.

[0048] Further preferably, it also includes an installation box 500, in which an installation cavity is provided, the furnace body 100 is located in the installation cavity, the smoke exhaust pipe 200 is provided at one end of the furnace body 100 and extends out of the installation box 500, the heating source is provided at the other end of the furnace body 100, and the circulating water tank 400 and the steam-water separator 300 are both provided on the side of the furnace body 100 and distributed along the length direction of the furnace body 100, the circulating water tank 400 is provided close to one end of the steam-water separator 300, and the steam-water separator is located at the other end of the furnace body 100.

[0049] In this embodiment, an installation cavity is also included to facilitate the relocation of the entire steam generating device. At the same time, the steam-water separator 300 is arranged close to the other end of the furnace body 100, so that the water in the coil 103 in the heating zone 101 can flow directly to the steam-water separator 300, thereby reducing the length of the flow path between the two. Similarly, the circulating water tank 400 is located at one end of the furnace body 100, so that the water in the circulating water tank 400 can flow into the furnace body 100 while reducing the length of the flow path.

[0050] It should be noted that, in the present application, the circulation control of the liquid can be achieved by installing a water pump on the pipeline.
