[0018] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the utility model.

[0019] It should be noted that when a component is referred to as "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are only for the purpose of illustration.

[0020] As shown in the Figure 1 accompanying drawings, the steam recovery device for a boiler of the present utility model includes a cylinder body 1. The upper and lower ends of the cylinder body 1 are respectively provided with a top cover 2 and a bottom plate 3, so as to form a sealed cavity, and water is injected into the cavity. An annular heat conduction pipe 4 is installed at one end of the cylinder body 1 close to the top cover 2. An steam inlet pipe 9 penetrating through to the outside of the cylinder body 1 is formed on the heat conduction pipe 4. The steam inlet pipe 9 is communicated with the steam discharge pipeline of the boiler, so that steam enters the heat conduction pipe 4. A condensation box 5 is installed at one end of the cylinder body 1 close to the bottom plate 3. A plurality of heat dissipation pipes 6 are communicated between the heat conduction pipe 4 and the condensation box 5. The heat dissipation pipes 6 are evenly distributed around the heat conduction pipe 4, so that steam enters the condensation box 5 along the heat dissipation pipes 6. The heat dissipation pipe 6 includes a first section 61 close to the heat conduction pipe 4 and a second section 62 close to the condensation box 5. The first section 61 is vertical, and the second section 62 is spiral. When the steam just enters the heat dissipation pipe 6, the temperature is relatively high, and the straight pipe is convenient for passage. After the steam flows through a certain distance, the temperature decreases, and it enters the spiral pipe for slow travel so as to fully dissipate heat. The heat passes through the heat dissipation pipe 6 into the surrounding water to heat the water. A plurality of heat dissipation fins 63 are spacedly connected to the outside of the first section 61 of the heat dissipation pipe 6 to increase the heat dissipation area and improve the heat dissipation efficiency.

[0021] A water inlet pipe 7 is connected to the top cover 2 to supplement water when the water volume in the cylinder body is insufficient. An outlet pipe 8 is connected to the bottom of the cylinder body 1 to recycle the hot water in the cylinder body 1. An outlet steam pipe 10 penetrating through to the outside of the cylinder body 1 is connected to the condensation box 5 to discharge the excess gas. A condensation water pipe 11 penetrating through to the outside of the cylinder body 1 is installed at the bottom of the condensation box 5 to discharge the liquid condensed from the steam. Valves are installed on the water inlet pipe 7, the outlet pipe 8, the steam inlet pipe 9, the outlet steam pipe 10 and the condensation water pipe 11 to facilitate the control of the flow of gas and liquid.

[0022] A motor 12 is installed on the top cover 2. A rotating shaft 13 extending into the cylinder body 1 is connected to the output shaft of the motor 12. A stirring blade 14 is installed on the rotating shaft 13. When rotating, it stirs the water in the cylinder body to make the water temperature uniform. A temperature detection device 15 for detecting the water temperature in the cylinder body 1 is installed on the cylinder body 1, so as to have real-time control over the temperature in the cylinder body, facilitate the adjustment of the steam flow rate, and better recover the steam heat.

[0023] When in use, open the valve on the steam inlet pipe to allow steam to flow into the heat conduction pipe. The steam enters the condensation box from the heat conduction pipe along the heat dissipation pipe. The heat of the steam seeps out from the heat dissipation pipe to heat the water in the cavity. The liquid formed after the steam condenses flows out from the condensate water pipe at the bottom of the condensation box, and the remaining gas is discharged from the steam outlet pipe, reducing heat loss and recycling the heat of the steam.

[0024] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
